Video games take off as a spectator sport

Editorial: "Give video games a sporting chance"

EVERY sport has its idols and superstars. Now video gaming is getting them too. Professional gaming, or e-sports, exploded in popularity in the US and Europe last year.

The scene has been big in Asia - particularly South Korea - for about a decade, with top players such as Lim Yo-Hwan earning six-figure salaries and competing for rock-star glory in Starcraft tournaments that attract audiences in the hundreds of thousands.

The phenomenon is taking off in the West partly because of improved video-streaming technology and large financial rewards. Video games are becoming a spectator sport, with certain players and commentators drawing massive online audiences.

And where people go, money follows. The second world championship of League of Legends - a team-based game in which players defend respective corners of a fantasy-themed battle arena - was held in Los Angeles in October. The tournament had a prize pool of $5 million for the season, with $1 million going to winning team Taipei Assassins, the largest cash prize in the history of e-sports.

League of Legends has also set records for spectator numbers. More than 8 million people watched the championship finals either online or on TV - a figure that dwarfs audience numbers for broadcasts of many traditional sports fixtures.

But gamers don't need to compete at the international level to earn money. Video-streaming software like Twitch makes it easy for players to send live footage to a website, where the more popular ones can attract upwards of 10,000 viewers - enough for some to make a living by having adverts in their video streams. Gamers can go pro without leaving their homes.

Currently, e-sports productions are handled by gaming leagues - but that could soon change. Last November saw two moves that will make it even easier to reach a global online audience. First, Twitch announced it would be integrating with Electronic Arts's Origin service, a widely used gaming platform. This would let gamers stream their play at the click of a button, making it easy for people around the world to watch.

Also in November came the latest release from one of gaming's biggest franchises, Call of Duty: Black Ops 2, which has the ability to live-stream via YouTube built into the game itself. Another feature allows the broadcast of in-game commentary for multiplayer matches.

"I think we will reach a point, maybe within five years, where spectator features are a necessity for all big game releases," says Corin Cole of e-sports publishing company Heaven Media in Huntingdon, UK.

David Ting founded the California-based IGN Pro League (IPL), which hosts professional tournaments. He puts the popularity of e-sports down to the demand for new forms of online entertainment. "After 18 months, IPL's viewer numbers are already comparable to college sports in the US when there's a live event," he says. "The traffic is doubling every six months."

Ting sees motion detection, virtual reality and mobile gaming coming together to make physical exertion a more common aspect of video games, blurring the line between traditional sport and e-sports. "Angry Birds could be this century's bowling," says Ting.

France braces for massive anti gay marriage protest

PARIS: Tens of thousands are set to march in Paris on Sunday to denounce government plans to legalise same-sex marriage and adoption which have angered many Catholics and Muslims, France's two main faiths.

Leading the charge is sassy phenomenon Frigide Barjot, whose real name is Virginie Tellenne and who has carved a career by creating a bizarre persona and cocking a snook at the establishment.

Her assumed name -- a play on the name of French film star Brigitte Bardot, a sex symbol in the 1960s -- translates as Frigid Loony.

Barjot has become a rallying symbol for the "March for All", articulating the feelings of many of those opposed to the government initiative.

"One cannot say that a child is born from two women," she says -- an argument espoused by opponents to the legislation in a country which is officially a secular republic but overwhelmingly Catholic.

The French parliament is to debate the bill -- one of the key electoral pledges of Socialist President Francois Hollande -- at the end of this month.

Preparations for the rally have gathered pace. Protesters across the country have hired as many as 90 coaches and five high-speed trains to head to Paris. They say they have distributed 4.5 million leaflets championing their cause.

There will be three different marches across the city which will converge near the Eiffel Tower.

Barjot said on Saturday she was expecting "between 200,000 and 300,000 people."

The march comes a day after France ordered tightened security in public buildings and transport as well as in places with large public gatherings after military action against radical Islamists in Mali and Somalia and threats of reprisals by the extremists.

A poll published Friday showed that 52 per cent of the French backed gay marriage but an equal number opposed same-sex adoption.

The head of the French Roman Catholic Church, Cardinal Andre Vingt-Trois, who has been vocal in his opposition of gay marriage, will not attend the protest. Nor will the chief rabbi Gilles Bernheim and Muslim Council head Mohammed Moussaoui take part in the street protests.

Far-right leader Marine Le Pen will also not be attending. Her National Front party is divided over the issue and has authorised those wanting to take part to do so despite officially taking the line that it was not backing the march.

Marchers have been instructed in leaflets not to react to provocation and told to "keep smiling in the face of invective ... seek discussion and if that fails, turn to the forces of law and order."

The controversy over the highly divisive issue gained momentum after the education minister asked Catholic schools to drop a plan to discuss the bill in schools, evoking France's traditional line of separation of the Church and the state.

French Muslim groups are joining in the opposition. The call has been led by the influential Union of French Islamic Organisations (UOIF) which urged co-religionists to join the march.

"This bill, if it passes, will disrupt family and social structures and civil law dangerously and irreparably," it said.

An earlier protest march on November 17 drew more than 100,000 people across France, with some 70,000 rallying in Paris alone.

Justice Minister Christiane Taubira has said the government will stick to the project, irrespective of the magnitude of the protest and has rejected calls for a referendum on the issue.

DENVER Baltimore's Justin Tucker kicked a 47-yard field goal 1:42 into the second overtime Saturday to lift the Ravens to a 38-35 victory over the Denver Broncos in the AFC playoffs.

The Ravens (12-6) forced overtime on a 70-yard touchdown pass from Joe Flacco to Jacoby Jones with 31 seconds left in regulation, after Jones slipped behind a pair of Broncos defenders along the sideline.

Late in the first overtime, Peyton Manning threw across his body on second down and Corey Graham picked off the ball to give the Ravens the ball on the Denver 45. Two plays later, the first overtime ended and the teams switched directions, and after three Ray Rice runs up the middle, Tucker sailed his game-winner through the uprights with room to spare.

Baltimore will travel to either New England or Houston for the AFC title game next Sunday, as linebacker Ray Lewis' career extends at least one more game.

Poisoned Lottery Winner's Kin Were Suspicious

Urooj Khan had just brought home his $425,000 lottery check when he unexpectedly died the following day. Now, certain members of Khan's family are speaking publicly about the mystery -- and his nephew told ABC News they knew something was not right.

"He was a healthy guy, you know?" said the nephew, Minhaj Khan. "He worked so hard. He was always going about his business and, the thing is: After he won the lottery and the next day later he passes away -- it's awkward. It raises some eyebrows."

The medical examiner initially ruled Urooj Khan, 46, an immigrant from India who owned dry-cleaning businesses in Chicago, died July 20, 2012, of natural causes. But after a family member demanded more tests, authorities in November found a lethal amount of cyanide in his blood, turning the case into a homicide investigation.

"When we found out there was cyanide in his blood after the extensive toxicology reports, we had to believe that ... somebody had to kill him," Minhaj Khan said. "It had to happen, because where can you get cyanide?"

Authorities could be one step closer to learning what happened to Urooj Khan. A judge Friday approved an order to exhume his body at Rosehill Cemetery in Chicago as early as Thursday to perform further tests.

Lottery Winner Murdered: Widow Questioned By Police Watch Video

Moments after the court hearing, Urooj Khan's sister, Meraj Khan, remembered her brother as the kind of person who would've shared his jackpot with anyone. Speaking at the Cook County Courthouse, she hoped the exhumation would help the investigation.

"It's very hard because I wanted my brother to rest in peace, but then we have to have justice served," she said, according to ABC News station WLS in Chicago. "So if that's what it takes for him to bring justice and peace, then that's what needs to be done."

Khan reportedly did not have a will. With the investigation moving forward, his family is waging a legal fight against his widow, Shabana Ansari, 32, over more than $1 million, including Urooj Khan's lottery winnings, as well as his business and real estate holdings.

Khan's brother filed a petition Wednesday to a judge asking Citibank to release information about Khan's assets to "ultimately ensure" that [Khan's] minor daughter from a prior marriage "receives her proper share."

Ansari may have tried to cash the jackpot check after Khan's death, according to court documents, which also showed Urooj Khan's family is questioning if the couple was ever even legally married.

Ansari, Urooj Khan's second wife, who still works at the couple's dry cleaning business, has insisted they were married legally.

She has told reporters the night before her husband died, she cooked a traditional Indian meal for him and their family, including Khan's daughter and Ansari's father. Not feeling well, Khan retired early, Ansari told the Chicago Sun-Times, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She said she called 911.

"It has been an incredibly hard time," she told ABC News earlier this week. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Ansari has not been named a suspect, but her attorney, Steven Kozicki, said investigators did question her for more than four hours.

Central African rivals agree unity government

LIBREVILLE: Central African Republic rebel groups on Friday signed a ceasefire deal with President Francois Bozize who agreed to set up a government of national unity and call new elections.

The accord was announced after three days of talks in the Gabon capital between the government and Seleka rebels who launched an offensive on December 10.

The rebels swept aside the impoverished country's army, but stopped just short of the capital Bangui.

The government and rebels signed a ceasefire accord. The two sides and Central African Republic's political opposition also signed two political accords allowing for the appointment of a prime minister from the opposition and setting out other power-sharing details, according to the United Nations.

The talks were organized by the Economic Community of Central African States (ECCAS) which had sent troops to the troubled country as Bozize faced mounting pressure.

Chad's President Idriss Deby, current ECCAS head, said the opposition and Bozize should start work on the transitional government "from tomorrow".

Under the accord, Bozize will be allowed to finish his mandate which ends in 2016 but he cannot replace the new prime minister during the transition period. Bozize has said he will not stand for a new term.

The agreement also calls for the withdrawal of "all foreign military forces" except those sent by the ECCAS countries. Seleka made this demand specifically to secure the withdrawal of about 200 South African troops sent in December.

The UN Security Council welcomed the signature of the ceasefire, in a statement, which "emphasized the necessity of an expeditious implementation of these agreements and called on all parties to implement them in good faith."

The 15-nation council "urged all parties to allow safe and unhindered access to peoples in need of humanitarian assistance as quickly as possible" and for all civilians held by armed groups to be released.

The violence in the country of some five million has affected more than 300,000 children, with child soldiers recruited and some girls forced to act as sex slaves, according to UN agencies.

The United Nations withdrew non-essential staff and the dependents of all workers in December as rebels neared Bangui.

The UN humanitarian department, OCHA, has voiced serious concern about the plight of civilians amid reports of widespread looting and violence.

The UN's World Food Programme, which has suspended its operations in the country, says hundreds of tonnes of food have been stolen from warehouses across the country.

Central African Republic has been notoriously unstable since its independence from France in 1960.

Bozize took power in a coup in 2003 and has since won two elections.

The rebels accused Bozize of failing to uphold earlier peace deals and had called for him to face war crimes charges at the International Criminal Court.

They also said he planned to modify the constitution to allow him to seek a third term in 2016.

Up to 500 soldiers from Gabon, Democratic Republic of Congo, Chad and Cameroon were sent after troubles in 2008. These troops have begun to pull out of the country.

Nearly 600 French troops are stationed in Bangui, officially to ensure the safety of the estimated 1,200 French nationals in the country.

Why death comes sooner in America

A report finds that Americans have "shorter lives and poorer health," coming in last in key areas behind 16 other rich nations

STORY HIGHLIGHTS

• Aaron Carroll: New study shows U.S. health and lifespan worst of 17 rich countries


• He says it's because of personal choices, systemic woes. Poverty high, health care uneven


• He says this particularly affects youth, plagued by sickness, violence, high mortality


• Carroll: Don't make it political. The richest country in the world must improve public health

Editor's note: Dr. Aaron E. Carroll is an associate professor of pediatrics at the Indiana University School of Medicine and the director of the university's Center for Health Policy and Professionalism Research. He blogs about health policy at The Incidental Economist and tweets at @aaronecarroll.

(CNN) -- A just-released report from the Institute of Medicine and National Research Council is making news by clearly illustrating that Americans have "shorter lives and poorer health." This is somewhat shocking, given how much we spend on health care each year — more than any of the 16 other rich countries surveyed in the study. What's even more upsetting is that this report focused quite heavily on people who are young. In the United States, even that group fared poorly.

Aaron Carroll

Why is this?

Some of the reasons involve choices make at a personal level. We eat too much, abuse drugs too often, wear seat belts too rarely and commit violence against each other to often.

Systemic issues are also to blame. We have higher levels of poverty than comparable countries, and our safety net programs are less capable of catching people when they fall. And too many also have too much trouble accessing the health care system, resulting in inefficient, ineffective and often absent care.

It's far too easy to let these dreadful statistics become obscured in a politically charged argument. Let's avoid that. This report is so stark that it's going to take a concerted effort on the part of the government, the media, the health care system and everyday citizens to turn things around. Our personal choices are bad. Our safety nets are bad. Our health care system is bad. It's all bad. How bad?

When compared with peer countries, the United States was the absolute worst with respect to still births, infant mortality and low birth weight. Some have tried to blame this on "coding" differences. In other words, they will claim that other countries will refuse to define a premature birth as we do, resulting in artificially high numbers in the United States. But when this report recalculated the rates to exclude such births equally in all countries, we still ranked last.

Things don't get better after birth. The chance that a child in the United States will die before age 5 is higher than in any of the other 16 peer countries. Injuries are the most common cause of death, but the United States also has the highest rate of deaths caused by negligence or abuse.

And violence is decidedly an American problem. Homicide is the third most common cause of death in children age 1-4.

From age 5-19, the trend continues. Kids this age in the United States have the worst health ranking of the 17 studied countries. More than one-third of U.S. children age 5-17 are obese or overweight, the highest of any peer country. The adolescent pregnancy rate in the United States is about 3.5 times the average of others. Additionally, the rates of sexually transmitted infections, including syphilis, gonorrhea and chlamydia are the worst compared to peer countries.

Nor are these children exempt from death. Injury deaths are more common in 15- to 19-year-olds in the United States than in any other studied country. Homicide claims the second highest number of lives in 15- to -24-year-olds, and 4 in 5 of those deaths involve guns. Males between the ages of 15 and 19 are five times as likely to die from violence in the United States than in other countries.

Even as young adults, ages 25-34, mortality remains consistently upsetting and preventable. Unintentional injuries remain the No. 1 cause of death. The risk of dying by violence remains seven times higher for males in the United States ages 20-24 than in other countries.

We have to work together to make these numbers better. Some of them can be improved with public health measures. We need to help Americans be less obese, to have fewer accidents and to commit less violence. There are lots of local studies and initiatives that propose ways to fix these things, but our public health system is woefully underfunded, and translating any promising findings to meaningful societal change poses a huge challenge.

We also need to improve our safety nets to help children at the lowest end of the socioeconomic ladder do better, even before they are born. Pregnant women, babies and children suffer from hunger and malnutrition far too often in the richest country in the world. Yet we still debate the merits of the federally funded WIC (Womens, Infants and Children) program, school lunches and food assistance to needy families.

Finally, we need to find a way to improve access to the health care system. The Medicaid program covers one in every three births and one in every three children in the United States, and it's still not enough. As some states balk at expanding Medicaid to cover many of the poorest uninsured, some are still talking about reducing funding to the already stretched program. There's no question that we have the capability, the knowledge and the resources to care for people. It's just a matter of doing it better.

There will be some who deny these results. Others will try to use them for political gain. That would be a mistake. We have to accept these findings and begin to work holistically to improve them. Being last just isn't the American way.

U.S. tells computer users to disable Java software

Updated 9:00 p.m. ET

WASHINGTON The U.S. Department of Homeland Security is advising people to temporarily disable the Java software on their computers to avoid potential hacking attacks.

The recommendation came in an advisory issued late Thursday, following up on concerns raised by computer security experts.

Experts believe hackers have found a flaw in Java's coding that creates an opening for criminal activity and other high-tech mischief.

CNET's Topher Kessler writes:

"The malware has currently been seen attacking Windows, Linux and Unix systems, and while so far has not focused on OS X, may be able to do so given OS X is largely similar to Unix and Java is cross-platform.

Even though the exploit has not been seen in OS X, Apple has taken steps to block it by issuing an update to its built-in XProtect system to block the current version of the Java 7 runtime and require users install an as of yet unreleased version of the Java runtime.

Luckily with the latest versions of Java, users who need to keep it active can change a couple of settings to help secure their systems. Go to the Java Control Panel that is installed along with the runtime, and in the Security section uncheck the option to "Enable Java content in the browser," which will disable the browser plug-in. This will prevent the inadvertent execution of exploits that may be stumbled upon when browsing the Web, and is a recommended setting for most people to do. If you need to see a Java applet on the Web, then you can always temporarily re-enable the plug-in.

The second setting is to increase the security level of the Java runtime, which can also be done in the same Security section of the Java Control Panel. The default security level is Medium, but you can increase this to High or Very High. At the High level, Java will prompt you for approval before running any unsigned Java code, and at the Very High level all Java code will require such approval, regardless of whether or not it is signed."

Java is a widely used technical language that allows computer programmers to write a wide variety of Internet applications and other software programs that can run on just about any computer's operating system.

Oracle Corp. bought Java as part of a $7.3 billion acquisition of the software's creator, Sun Microsystems, in 2010.

Oracle, which is based in Redwood Shores, Calif., had no immediate comment late Friday.

CDC: Flu Outbreak Could Be Waning

The flu season appears to be waning in some parts of the country, but that doesn't mean it won't make a comeback in the next few weeks, according to the Centers for Disease Control and Prevention.

Five fewer states reported high flu activity levels in the first week of January than the 29 that reported high activity levels in the last week of December, according to the CDC's weekly flu report. This week, 24 states reported high illness levels, 16 reported moderate levels, five reported low levels and one reported minimal levels, suggesting that the flu season peaked in the last week of December.

"It may be decreasing in some areas, but that's hard to predict," CDC Director Dr. Thomas Frieden said in a Friday morning teleconference. "Trends only in the next week or two will show whether we have in fact crossed the peak."

The flu season usually peaks in February or March, not December, said Dr. Jon Abramson, who specializes in pediatric infectious diseases at Wake Forest Baptist Health in North Carolina. He said the season started early with a dominant H3N2 strain, which was last seen a decade ago, in 2002-03. That year, the flu season also ended early.

Increasing Flu Cases: Best Measures to Ensure Your Family's Health Watch Video

Because of the holiday season, Frieden said the data may have been skewed.

For instance, Connecticut appeared to be having a lighter flu season than other northeastern states at the end of December, but the state said it could have been a result of college winter break. College student health centers account for a large percentage of flu reports in Connecticut, but they've been closed since the fall semester ended, said William Gerrish, a spokesman for the state's department of public health.

The flu season arrived about a month early this year in parts of the South and the East, but it may only just be starting to take hold of states in the West, Frieden said. California is still showing "minimal" flu on the CDC's map, but that doesn't mean it will stay that way.

Click here to read about how flu has little to do with cold weather.

"It's not surprising. Influenza ebbs and flows during the flu season," Frieden said. "The only thing predictable about the flu is that it is unpredictable."

Dr. William Schaffner, chair of preventive medicine at Vanderbilt University Medical Center in Nashville, Tenn., said he was expecting California's seeming good luck with the flu to be over this week.

"Flu is fickle, we say," Schaffner said. "Influenza can be spotty. It can be more severe in one community than another for reasons incompletely understood."

Early CDC estimates indicate that this year's flu vaccine is 62 percent effective, meaning people who have been vaccinated are 62 percent less likely to need to see a doctor for flu treatment, Frieden said.

Although the shot has been generally believed to be more effective for children than adults, there's not enough data this year to draw conclusions yet.

"The flu vaccine is far from perfect, but it's still by far the best tool we have to prevent flu," Frieden said, adding that most of the 130 million vaccine doses have already been administered. "We're hearing of shortages of the vaccine, so if you haven't been vaccinated and want to be, it's better late than never."

Muscle mimic pulls electricity from wet surface

Electricity has been squeezed from a damp surface for the first time, thanks to a polymer film that curls up and moves – a bit like an artificial muscle – when exposed to moisture. The film could be used to run small, wearable devices on nothing but sweat, or in remote locations where conventional electricity sources aren't available.

When a dry polymer absorbs water, its molecular structure changes. This can, in principle, be converted into larger-scale movement, and in turn electricity. But previous attempts at creating a material powered by a moisture gradient – the difference in chemical potential energy between a wet region and a dry region - failed to produce a useful level of force.

These unsuccessful tries used a polymer called polypyrrole. Now Robert Langer and colleagues at the Massachusetts Institute of Technology have turned to the material again, embedding chains of it within another material, polyol-borate. This more complex arrangement mimics structures found in muscles as well as in plant tissues that bend in response to changes in humidity.

Flipping film

The result looks like an ordinary piece of thin black plastic, but when placed on a wet surface, something extraordinary happens. As the material absorbs water, its end curls away from the surface and the film becomes unstable, so it flips over. The ends have now dried out, so they are ready to absorb more water, and the whole process repeats itself. This continuous flipping motion lets the film travel across a suitably moist surface unaided.

Langer found that a 0.03-millimetre-thick strip, weighing roughly 25 milligrams, could curl up and lift a load 380 times its mass to a height of 2 millimetres. It was also able to move sideways when carrying a load about 10 times its mass.

To extract energy from this effect, Langer's team added a layer of piezoelectric material – one which produces electricity when squeezed. When this enhanced film, weighing about 100 milligrams, flipped over, it generated an output of 5.6 nanowatts – enough to power a microchip in sleep mode.

Electricity from sweat

Though the output is small, it is proof that electricity can be extracted from a water gradient. "To the extent of our knowledge, we are the first to utilise a water gradient, without a pressure gradient, to generate electricity," says Langer.

Large-scale energy harvesting is unlikely as the size of the device needed would be impractical, but it could be used to power small devices such as environmental monitoring systems in remote locations. "It will be interesting for applications where the amount of energy needed may be low but where access to energy may be difficult," says Peter Fratzl at the Max-Planck Institute of Colloids and Interfaces in Potsdam, Germany, who was not involved in the work.

Another application, Langer suggests, would be to place the film inside the clothing of joggers or athletes. The evaporation of sweat could generate enough electricity to power sensors monitoring blood pressure and heart rate.

Python clings to Qantas wing on two-hour flight

SYDNEY: It was not quite a "Snakes on a Plane" scenario, but passengers on a Qantas jet watched in amazement as a three-metre (nine feet) python clung to the outside of their aircraft during a flight.

The Australian carrier said the flight from the Queensland city of Cairns to Port Moresby, capital of the Pacific island nation of Papua New Guinea, took off early Thursday morning with the unintended passenger tucked into its wing.

"The snake was seen by passengers once (the plane) reached cruising altitude," a Qantas spokesman told AFP.

"It was still on the aircraft when it arrived in Port Moresby but it had died by that stage."

Once they spotted it on the wing, passengers watched as the reptile engaged in a life-and-death struggle to maintain its grip on the plane despite the winds and chilly altitude temperatures for the two-hour journey.

Passenger Robert Weber told Fairfax Media Friday that while people at the front of the plane were unaware of the python, those at the back were "all totally focused on the snake and how it might have got onto the aircraft".

Unlike the 2006 "Snakes on a Plane" movie starring Samuel L. Jackson, this reptile did not affect the flight.

"There was no panic. At no time did anyone stop to consider that there might be others on board," Weber said.

He added that the snake had been nestled neatly at first, but once the wind caught the end of its tail, it was "pulling him straight out" and from then on it became a hopeless "life-and-death struggle".

"I felt quite sad for it, really," he said.

An expert said the snake was probably a scrub python, Australia's longest snake and one common in northern Queensland.

Qantas said it had never heard of anything similar happening before, adding that there was no way the reptile could have accessed the cabin.

(CNN) -- Rizana Nafeek was a child herself -- 17 years old according to her birth certificate -- when a four-month-old baby died in her care in Saudi Arabia. She had migrated from Sri Lanka only weeks earlier to be a domestic worker for a Saudi family.

Although Rizana said the baby died in a choking accident, Saudi courts convicted her of murder and sentenced her to death. On Wednesday, the Saudi government carried out the sentence in a gruesome fashion, by beheading Rizana.

Rizana's case was rife with problems from the beginning. A recruitment agency in Sri Lanka knew she was legally too young to migrate, but she had falsified papers to say she was 23. After the baby died, Rizana gave a confession that she said was made under duress -- she later retracted it. She had no lawyer to defend her until after she was sentenced to death and no competent interpreter during her trial. Her sentence violated international law, which prohibits the death penalty for crimes committed before age 18.

Rizana's fate should arouse international outrage. But it should also spotlight the precarious existence of other domestic workers. At least 1.5 million work in Saudi Arabia alone and more than 50 million -- mainly women and girls -- are employed worldwide according to the International Labour Organization (ILO).

Again according to the ILO, the number of domestic workers worldwide has grown by more than 50% since the mid-1990s. Many, like Rizana, seek employment in foreign countries where they may be unfamiliar with the language and legal system, and have few rights.

When Rizana traveled to Saudi Arabia, for example, she may not have known that many Saudi employers confiscate domestic workers' passports and confine them inside their home, cutting them off from the outside world and sources of help.

It is unlikely that anyone ever told her about Saudi Arabia's flawed criminal justice system, or that while many domestic workers find kind employers who treat them well, others are forced to work for months or even years without pay, and subjected to physical or sexual abuse.

Conditions for migrant domestic workers in Saudi Arabia are among some of the worst, but domestic workers in other countries rarely enjoy the same rights as other workers. In a new report this week, the International Labour Organization says that nearly 30% of the world's domestic workers are completely excluded from national labor laws. They typically earn only 40% of the average wage of other workers. Forty-five percent aren't even entitled by law to a weekly day off.

Last year, I interviewed young girls in Morocco who worked 12 hours a day, 7 days a week for a fraction of the minimum wage. One girl began working at age 12 and told me: "I don't mind working, but to be beaten and not to have enough food, this is the hardest part."

Many governments have finally begun to recognize the risks and exploitation domestic workers face. During 2012, dozens of countries took action to strengthen protections for domestic workers. Thailand, and Singapore approved measures to give domestic workers a weekly day off, while Venezuela and the Philippines adopted broad laws for domestic workers ensuring a minimum wage, paid holidays, and limits to their working hours. Brazil is amending its constitution to state that domestic workers have all the same rights as other workers. Bahrain codified access to mediation of labor disputes.

Perhaps most significantly, eight countries acted in 2012 to ratify -- and therefore be legally bound by -- the Domestic Workers Convention, with more poised to follow suit this year. The convention is a groundbreaking treaty adopted in 2011 to guarantee domestic workers the same protections available to other workers, including weekly days off, effective complaints procedures and protection from violence.

The Convention also has specific protections for domestic workers under the age of 18 and provisions for regulating and monitoring recruitment agencies. All governments should ratify the convention.

Many reforms are needed to prevent another tragic case like that of Rizana Nafeek. The obvious one is for Saudi Arabia to stop its use of the death penalty and end its outlier status as one of only three countries worldwide to execute people for crimes committed while a child.

Labor reforms are also critically important. They may have prevented the recruitment of a 17 year old for migration abroad in the first place. And they can protect millions of other domestic workers who labor with precariously few guarantees for their safety and rights.

Sheriff: Calif. teen planned attack on classmates

Updated at 9:40 p.m. ET

TAFT, Calif. A 16-year-old student armed with a shotgun walked into a rural California high school on Thursday, shot one student and fired at others and missed before a teacher and another staff member talked him into surrendering, officials said.

The teen victim was in critical but stable condition, and the suspect, whose pockets were stuffed with ammunition, was still being interrogated, Kern County Sheriff Donny Youngblood said at a news conference Thursday evening.

The suspect used a shotgun that belonged to his brother and went to bed Wednesday night with a plan to shoot two fellow students, Youngblood said.

Surveillance video shows the alleged shooter trying to conceal the gun as he nervously entered Taft Union High School through a side entrance after school had started Thursday morning.

When the shots were fired, teacher Ryan Heber tried to get the more than two dozen students out a back door and engaged the shooter in conversation to distract him, Youngblood said. Campus supervisor Kim Lee Fields responded to a call of shots fired and also began talking to the teen.

"They talked him into putting that shotgun down. He in fact told the teacher, `I don't want to shoot you,' and named the person that he wanted to shoot," Youngblood said.

"The heroics of these two people goes without saying. ... They could have just as easily ... tried to get out of the classroom and left students, and they didn't," the sheriff said. "They knew not to let him leave the classroom with that shotgun."

The shooter didn't show up for first period, then interrupted the class of 28 students.

Youngblood said the suspect alleges the two students he targeted had bullied him for more than a year, but the sheriff couldn't confirm the allegations.

"Certainly he believed that the two people he targeted had bullied him, in his mind. Whether that occurred or not we don't know yet," Youngblood said.

Youngblood did not release the student's disciplinary record, saying he didn't have it.

The shotgun is believed to belong to the boy's brother and was in the boy's home, Youngblood said.

The Sheriff's Department did not release the boy's name because he was a juvenile and had yet to be charged. But many students and community members said they knew the boy and said he was often teased, including Alex Patterson, 18, who went to Taft with the suspect before graduating last year.

"He comes off as the kind of kid who would do something like this," Patterson said. "He talked about it a lot, but nobody thought he would."

Trish Montes, who lived next door to the suspect, said he was "a short guy" and "small" who was teased about his stature by many, including the victim.

"Maybe people will learn not to bully people," Montes said. "I hate to be crappy about it, but that kid was bullying him."

Montes said her son had worked at the school and tutored the boy last year, sometimes walking with him between classes because he felt sorry for him.

"All I ever heard about him was good things from my son," Montes said. "He wasn't Mr. Popularity, but he was a smart kid. It's a shame. My kid said he was like a genius. It's a shame because he could have made something of himself."

The wounded student was flown to a hospital in Bakersfield and was listed in stable but critical condition Thursday evening. Officials said a female student was hospitalized with possible hearing damage because the shotgun was fired close to her ear, and another girl suffered minor injuries during the scramble to flee when she fell over a table.

Officials said there's usually an armed officer on campus, but the person wasn't there because he was snowed in. Taft police officers arrived within 60 seconds of first reports.

Bakersfield television station KERO reported receiving phone calls from people inside the school who hid in closets. About 900 students are enrolled at the high school, which includes ninth through 12th grades.

Wilhelmina Reum, whose daughter Alexis Singleton is a fourth-grader at a nearby elementary school, got word of the attack while she was about 35 miles away in Bakersfield and immediately sped back to Taft.

"I just kept thinking this can't be happening in my little town," she told The Associated Press.

"I was afraid I was going to get hurt," Alexis said. "I just wanted my mom to get here so I could go home."

Taft is a community of fewer than 10,000 people amid oil and natural gas production fields about 120 miles northwest of Los Angeles.

The attack there came less than a month after a gunman massacred 20 children and six women at Sandy Hook Elementary School in Newtown, Conn., then killed himself.

That shooting prompted President Barack Obama to promise new efforts to curb gun violence. Vice President Joe Biden, who was placed in charge of the initiative, said he would deliver new policy proposals to the president by next week.

Sen. Dianne Feinstein, D-Calif., said in a statement that her father had attended Taft Union and she has visited the school over the years.

"At this moment my thoughts and prayers are with the victims, and I wish them a speedy recovery," Feinstein said. "But how many more shootings must there be in America before we come to the realization that guns and grievances do not belong together?"

Judge: Holmes Can Face Trial for Aurora Shooting

In a ruling that comes as little surprise, the judge overseeing the Aurora, Colo., theater massacre has ordered that there is enough evidence against James Holmes to proceed to a trial.

In an order posted late Thursday, Judge William Sylvester wrote that “the People have carried their burden of proof and have established that there is probable cause to believe that Defendant committed the crimes charged.”

The ruling came after a three-day preliminary hearing this week that revealed new details about how Holmes allegedly planned for and carried out the movie theater shooting, including how investigators say he amassed an arsenal of guns and ammunition, how he booby-trapped his apartment to explode, and his bizarre behavior after his arrest.

PHOTOS: Colorado ‘Dark Knight Rises’ Theater Shooting

Holmes is charged with 166 counts, including murder, attempted murder and other charges related to the July 20 shooting that left 12 people dead and 58 wounded by gunfire. An additional 12 people suffered non-gunshot injuries.

One of the next legal steps is an arraignment, at which Holmes will enter a plea. The arraignment was originally expected to take place Friday morning.

Judge Sylvester indicated through a court spokesman that he would allow television and still cameras into the courtroom, providing the outside world the first images of Holmes since a July 23 hearing. Plans for cameras in court, however, were put on hold Thursday afternoon.

“The defense has notified the district attorney that it is not prepared to proceed to arraignment in this case by Friday,” wrote public defenders Daniel King, Tamara Brady and Kristen Nelson Thursday afternoon in a document objecting to cameras in court.

A hearing in the case will still take place Friday morning. In his order, Judge Sylvester said it should technically be considered an arraignment, but noted the defense has requested a continuance.  Legal experts expect the judge will grant the continuance, delaying the arraignment and keeping cameras out of court for now.

Sylvester also ordered that Holmes be held without bail.

Holmes’ attorneys have said in court that the former University of Colorado neuroscience student is mentally ill. The district attorney overseeing the case has not yet announced whether Holmes, now 25, can face the death penalty.

Hints of new dark force seen in galactic smash-ups

Colliding clusters of galaxies may hold clues to a mysterious dark force at work in the universe. This force would act only on invisible dark matter, the enigmatic stuff that makes up 86 per cent of the mass in the universe.

Dark matter famously refuses to interact with ordinary matter except via gravity, so theorists had assumed that its particles would be just as aloof with each other. But new observations suggest that dark matter interacts significantly with itself, while leaving regular matter out of the conversation.

"There could be a whole class of dark particles that don't interact with normal matter but do interact with themselves," says James Bullock of the University of California, Irvine. "Dark matter could be doing all sorts of interesting things, and we'd never know."

Some of the best evidence for dark matter's existence came from the Bullet cluster, a smash-up in which a small galaxy cluster plunged through a larger one about 100 million years ago. Separated by hundreds of light years, the individual galaxies sailed right past each other, and the two clusters parted ways. But intergalactic gas collided and pooled on the trailing ends of each cluster.

Mass maps of the Bullet cluster showed that dark matter stayed in line with the galaxies instead of pooling with the gas, proving that it can separate from ordinary matter. This also hinted that dark matter wasn't interacting with itself, and was affected by gravity alone.

Musket shot

Last year William Dawson of the University of California, Davis and colleagues found an older set of clusters seen about 700 million years after their collision. Nicknamed the Musket Ball cluster, this smash-up told a different tale. When Dawson's team analysed the concentration of matter in the Musket Ball, they found that galaxies are separated from dark matter by about 19,000 light years.

"The galaxies outrun the dark matter. That's what creates the offset," Dawson said. "This is fitting that picture of self-interacting dark matter." If dark matter particles do interact, perhaps via a dark force, they would slow down like the gas.

This new picture could solve some outstanding mysteries in cosmology, Dawson said this week during a meeting of the American Astronomical Society in Long Beach, California. Non-interacting dark matter should sink to the cores of star clusters and dwarf galaxies, but observations show that it is more evenly distributed. If it interacts with itself, it could puff up and spread outward like a gas.

So why doesn't the Bullet cluster show the same separation between dark matter and galaxies? Dawson thinks it's a question of age – dark matter in the younger Bullet simply hasn't had time to separate.

New window

The idea complements a previous study that saw evidence for dark forces at work in the Bullet cluster. In 2007 Glennys Farrar of New York University and colleagues said that the smaller cluster was moving too fast for gravity alone to be responsible. They suggested that some mysterious force related to dark matter might be hurrying it along.

Still, two clusters is not a lot to go on. Dawson, Bullock and colleagues are following up with about 20 more galactic collisions to see if they show any unusual behaviours. "I really think that we're almost to the point where we have enough observational data in hand," Dawson said. "We could close the book on self-interacting dark matter."

If the new force does exist, we might soon be able to see its effects on things influenced by dark matter, such as the behavior of black holes or the masses of the first stars, says Douglas Finkbeiner of Harvard University in Cambridge, Massachusetts, who was not involved in the new study.

"The simple thing isn't always the right thing, so I really appreciate that Will is trying to look into these other possibilities," he says.

Louis Strigari of Stanford University in California agrees. "Self-interacting dark matter is worth pursuing because we're still very ignorant," he said. "We're desperate to understand what dark matter is, so any new window is welcome."

Latino should have played lead in 'Argo'

Ben Affleck plays the lead role of Tony Mendez in "Argo," which he also directed.

STORY HIGHLIGHTS

• Oscar nominations on Thursday, and Ben Affleck expected to get one for "Argo"


• Affleck plays real-life Latino who helped diplomats escape in Iran hostage crisis


• Ruben Navarrette: Affleck should have used a Latino actor to play role


• He says it cheats actor out of a job, and the Latino community out of a hero's story

San Diego, California (CNN) -- The upcoming Oscars are no stranger to causes or controversy. And this year, there is a strong dose of both surrounding the film "Argo" -- and its star and director, Ben Affleck.

This controversy bubbled up when the buzz started that Affleck could get an Academy Award nomination for best director when the announcements are made Thursday.

"Argo" tells how an ingenious and daring CIA agent helped orchestrate the rescue of six U.S. diplomats from Tehran during the Iran hostage crisis of 1979-1980. In November 1979, about 300 Islamic students stormed the U.S. Embassy and 66 Americans were taken hostage. But six U.S. diplomats escaped and were hidden at the Canadian Embassy by the Canadian ambassador and his wife.

Ruben Navarrette Jr.

The CIA agent -- Antonio "Tony" Mendez, played by Affleck -- successfully led the mission to evacuate the Americans, which involved Mendez and his associates posing as a Canadian film crew that was eager to make a movie in Iran.

The real Tony Mendez was awarded the Intelligence Star for Valor, and other honors, for leading the rescue. He later wrote a memoir, detailing the events in Tehran.

"Argo" is loosely based on Mendez's book. Better make that, very loosely based. As movie critics and others have pointed out since the movie opened a few months ago, the filmmakers took lots of dramatic license with the story. Mendez's role is played up, while that of the Canadians who helped hide and protect the Americans is played down. Some scenes depicted in the film never happened. Some characters are composites of several real people.

In other words, it's what you would expect from a Hollywood feature film based on a historical event. It's not a documentary. It's meant to be taken with a grain of salt, and to be entertaining.

Still, there are some Latinos -- in and out of Hollywood -- who think that, in this case, the filmmakers, and especially Affleck, pushed the concept of creativity too far. They say Affleck missed an opportunity to put more Latinos on screen. Moreover, they say, Affleck improperly claimed, for himself, the choice role of Mendez when he should have cast a Latino actor instead. They insist that the director didn't just cheat a Latino out of an acting job but the Latino community out of a feel-good story about one of their own who won acclaim for a heroic deed.

The critics are right, and their cause is just. Affleck should have tried to cast a Latino to play Mendez. That's common sense, and it would have made "Argo" a better movie. Affleck also didn't do himself any favors by trying to dismiss the criticism with a glib remark that essentially said that it really doesn't matter that the actor playing Mendez isn't Latino since Mendez himself isn't, shall we say, overtly Latino.

At a recent forum intended to publicize the film, Affleck responded to a question from the audience about the controversy by noting that "Tony does not have, I don't know what you would say, a Latin/Spanish accent" and that "You wouldn't necessarily select him out of a line of 10 people and go 'This guy's Latino.' "

Ouch. At least Affleck didn't slip and say "line up."

"So I didn't feel as though I was violating something," he said, "where, here's this guy who's clearly ethnic in some way and it's sort of being whitewashed by Ben Affleck the actor."

Johnny Depp set a better example. Several months ago, Depp turned down the role of Mexican revolutionary Francisco "Pancho" Villa in another film. He said that the role should go to a Latino. I praised Depp at the time for showing that, besides being a great actor, he is also a person of character.

The exclusion of Latinos from Hollywood is an old story. This is still a black and white world, where Latinos rarely get cast in the leading role. We're the gardeners and housekeepers, the gang leader and drug dealers, the nannies and farm workers. That's it. There has been some progress, of course. But not enough -- not when you have a Latina in the Supreme Court, three Latinos in the U.S. Senate, and Latinos heading Fortune 500 companies.

I could blame the environment of Southern California, in which most Hollywood writers, producers and directors live and spend most of their time. When they get up in the morning and drive to work, most Latinos they encounter are subservient. We clean their homes, cook their breakfast, trim their hedges, park their cars and otherwise help them get through the day.

Still, you can push this argument too far, and wind up going down a dangerous path -- one that ultimately sets back the greater cause of trying to get television networks and film studios to create a broader range of meatier roles for Latino actors and actresses.

After all, it's a short walk from saying that a director should have cast a Latino to play a Latino to arguing that only Latinos can play Latinos. And, if that's the argument, then on what moral high ground do Latinos stand to also push -- as we should -- for Latino actors and actresses to be considered for generic and mainstream roles that could have gone to white actors? We can't have it both ways.

Even if Latinos succeed in making their point about this one director and this one movie, it could backfire. We could win this battle, and still lose the war.

But before Latinos can be fully integrated into America and not considered outsiders, we have to take every opportunity to push for inclusion and fairness. And acknowledging that Latinos have the skills to play themselves is a good start.

Leaked video shows teens joking about Ohio rape case

The threats are part of a series of online messages that have targeted individuals and authorities in Steubenville amid increased attention over two high school football players who are facing rape charges.

Jefferson County Sheriff Fred Abdalla said Wednesday he'd provided the FBI a copy of an anonymous Facebook post in which someone threatened to kill his family.

Steubenville Police Chief William McCafferty said he gave the FBI an email that he had opened Wednesday morning, which then disabled his computer.

FBI spokesman Todd Lindgren said he could not immediately comment.

The two teenage boys are set for trial next month in juvenile court on charges they raped a 16-year-old in August. Their attorneys have denied the charges in court.

Much of the evidence in the case played out on social media, in which the photos of the seemingly unconscious girl were posted online. A video published and then deleted from YouTube shows a third freshman, Michael Nodianos, joking about the alleged rape.

The hacking collective Anonymous has staged rallies in support of the alleged victim, and hackers were able to dig up and re-post the deleted YouTube video online.

According to the Steubenville Herald Star, Nodianos' attorney said someone hacked into his client's email and social media accounts, as well as the email accounts of his family members. He has since dropped out of Ohio State University, where he was slated to attend on a scholarship.

Arias Caught Lying to Cops in Recorded Phone Calls

Jodi Arias blatantly lied to police who asked her about Travis Alexander's death, telling them in recorded phone calls that she kept trying to call and message Alexander the week of his death but never heard back from him.

The phone calls were played as evidence during the fourth day of Arias' trial, in which she is charged with murder and could face the death penalty if convicted of killing Alexander in a "depraved and heinous" way. Arias has admitted to killing her former boyfriend, but claims it was self-defense.

During the phone conversations played in court, Arias can be heard telling Mesa, Ariz., detective Esteban Flores that she last talked to Alexander on Tuesday night, June 3, 2008, around 10 p.m. She had been in Los Angeles, about to leave to go to Utah to visit a new love interest, she said.

After June 3, he stopped calling her back, she said.

Photos of Key Players and Evidence in the Jodi Arias Murder Trial

"On Tuesday night (I talked to him), it was brief though, 10 o'clock maybe. I'd say 10 p.m. or 9 - 9:30. I was calling people because I was bored on the road. He was nice and cordial, but kind of acting like he had hurt feelings," she said.

"I may have called him Wednesday, from the road, and I sent him a couple of text messages, and a couple of pictures," she said, though Alexander didn't pick up and his voice mailbox was full. "That's unusual. He deletes all of his messages. I didn't want to be obsessive about it because we're not together anymore and I didn't like to call too much."

According to court records, Arias, 32, actually went to Alexander's home on in Mesa on Wednesday morning. There, the pair had sex and took graphic photos of one another with Alexander's camera.

Then, Arias is believed to have killed Alexander, 30, in his shower by stabbing him, slashing his throat from ear to ear, and shooting him in the head.

In the phone conversations, Arias told Flores that she considered calling Alexander's friends when he stopped returning her calls on Wednesday, but didn't want to act like "his mother."

Alexander's friends found his body five days later with stab wounds and a bullet wound, lying in blood in his home.

Flores asked Arias if she ever considered buying a gun, she said she was too scared of handguns.

"I've looked into handguns. I have a list of things I'm scared of that I'm trying to overcome," she said. "I got that from Travis, you know, to push yourself out of your comfort zone, and do things you're afraid of. But handguns are expensive and not really in my price range right now."

Arias is accused of stealing her grandmother's handgun and using it to shoot Alexander in the head during the attack.
The detective interviewed Arias by phone multiple times in June after Alexander's body was discovered by his friends on June 9.

Arias was indicted on July 9, 2008, and changed her story again before her arraignment, telling a TV news station that she was at Alexander's house when he was killed and witnessed two intruders kill him.

After she was arraigned, Arias told police she killed Alexander, but did it in self-defense. Arias's attorneys have said that Alexander was controlling and abusive toward Arias, and described him as a "sexual deviant."

In earlier testimony in court today, Arias's new love interest, Ryan Burns, testified that Arias showed up to his house on the morning of Thursday, Dec. 5, just 24 hours after she killed Alexander.

There, the pair cuddled, kissed, and watched movies, according to Burns.

Burns, who met Arias at a business conference in spring, 2008, said he exchanged frequent long phone calls and online conversations with Arias before inviting her to come visit him in West Jordan, Utah, in June. Arias lived in California at the time.

She arrived at Burns's home 24 hours after she was expected there, telling him that she got lost, drove the wrong way on a freeway for a few hours, fell asleep for awhile, and then got lost again, Burns testified today.

She never told him that she had confronted Alexander with a knife or gun and ended up killing him just hours before their date.

When she arrived, the pair quickly got physical, he testified.

"We went back to my house. We talked for awhile, and agreed that we were going to watch a movie. At some point we were talking and we kissed. Every time we started kissing it got a little more escalated. Our clothes never came off, but at some point she was kissing my neck, I was kissing hers, but our clothes never came off," he said.

Burns said that both he and Arias stopped kissing at the time, though they again became physically involved later in the evening when Arias climbed on top of Burns and began kissing him. Burns said that they stopped kissing because he did not want her to "regret the visit" because of her Mormon beliefs about sex.

He also told prosecutors upon questioning that Arias was physically strong.

"She's very fit," he said, describing their encounter when she climbed on top of him. "She's very strong. She has close to a six pack (of abs)."

Prosecutors likely asked about the strength of Arias because in testimony Tuesday Maricopa County medical examiner Kevin Horn said Alexander was stabbed so forcefully that the blade chipped his skull and his neck was cut all the way back to the spinal cord.

Burns, who is also a Mormon, said he noticed two bandages on Arias's hand when she arrived at his house, which she told him she got when a glass broke at her place of employment, Margaritaville.

During her visit, the pair also went to a business meeting and went out with Burns' friends where Burns described Arias as acting "shy" and a "little awkward."

"She was fine, she was laughing about simple little things like any other person. I never once felt like anything was wrong during the day. With a crowd she was a little awkward in social areas, but one on one she was very talkative and excitable," he said.

Pruney fingers give us better grip underwater

WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.

Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.

To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.

With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.

So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Japan plans US$2.1b military spend in stimulus package: official

TOKYO: Japan plans to spend $2.1 billion on its military over the next few months as part of a huge stimulus package, a defence ministry official said Wednesday, amid growing concerns over a rising China.

The cash is in addition to the regular military spending for 2012-13 and is separate from a boosted budget request for next fiscal year that ruling party policy makers called for on Tuesday.

"We will request 180.5 billion yen to be allocated to military spending from a stimulus package," a defence ministry spokesman told AFP, adding that some of the cash will be used to buy PAC-3 surface-to-air anti-ballistic missile systems and modernise four F-15 fighter jets.

The request for funds has to be approved by the finance ministry before being officially included in the stimulus the government is set to announce later this month, reportedly worth 13.1 trillion yen for this fiscal year to March.

The announcement came a day after Prime Minister Shinzo Abe's ruling Liberal Democratic Party said Japan will increase military spending for the first time in 11 years next fiscal year starting from April.

Japan is involved in a territorial tussle with China over a group of uninhabited islands in the East China Sea. Beijing has sent vessels to the area dozens of times and late last year dispatched a plane.

Nerves in Tokyo have also been rattled by an unpredictable North Korea. It sent a rocket over Japan's southern islands last month in what it insisted was a satellite launch. Tokyo and its allies said the launch was a covert ballistic missile test.

"Out of 180.5 billion yen, the defence ministry plans to use 60.5 billion yen to prepare for the changing security environment surrounding Japan," the spokesman said.

The defence ministry also plans to purchase three SH-60K patrol helicopters and to add a battery for an intermediate-range ballistic missile system, he said.
