they could if we did not stop them first. so this is a just war, a war waged proportionally in last resort and in self-defense. >> obama says terrorists threaten americans at home and abroad. he points to last year's attack on the u.s. embassy in libya and the boston bombings in april. he says strikes by unmanned aircraft are legal under domestic and international law. and that he has put checks in place, but he vows his administration will review proposals to extend oversight. the president acknowledges u.s. drones have caused civilian deaths. but he says there would be more civilian casualties if the country did nothing. he argues the strikes are preferable to a ground war. some members of congress and others have questioned whether carrying out drone attacks are legal. pakistan's presumptive prime minister is facing increasing public anger over drone strikes

in his country. nhk world's reporter has the details. >> reporter: pakistani opposition party in this month's election were critical of the u.s. drone attacks against islamic militants in pakistan. sharif has said he will stand against barack obama's drone attacks. he is expected to resume the post of prime minister for the third time. >> drones indeed challenge our sovereignty. also, we have taken this matter very seriously. >> reporter: pakistan's sovereignty is a key topic when people discuss pakistan's relations. anti-u.s. sentiment when the u.s. military killed osama bin

laden in pakistan two years ago without informing the pakistani government. the cities of u.s. drone strikes that followed fueled that anger. the people also criticized government officials who agreed to cooperate with barack obama's anti-terror policies. pakistan drilled this month that the unmanned drone attacks were in violation of the country's sovereign sovereignty. it also said they should consider canceling diplomatic relations with the u.s. or even shooting the drones down if the u.s. continues the attacks. however, pakistan's military depends heavily on the u.s. for financial assistance. some military officials are opposed to upsetting the relationship with the united states.

>> the drone decisions are made by the army. they're not made by the politicians. and i think they will continue because the army will continue to cooperate with the americans. >> reporter: sharif must first persuade the men in uniform before he can start negotiating with barack obama. obama's latest speech on thursday justifying the drone strikes is expected to further ignite anti-u.s. sentiment in pakistan. sharif will feel the pressure as soon as he comes into office. nhk world, islamabad. police in britain have arrested two more people in connection with the killing of a soldier in london. a man and a woman are suspected of conspiracy to murder. investigators believe they may have helped the two men carrying out the attack. british media say those suspects

were known to security services. two men approached the soldier on wednesday near a military barracks in southeast london. they were armed with weapons including a meat cleaver. then they hacked him to death. the british ministry of defense identified the victim as lee rigby, a veteran of the war in afghanistan. he was 25 years old and had a 2-year-old son. police arrested the two men soon after the attack but have yet to name them. they say one is 22 years old. the other, 28. media in britain have identified the 28-year-old as a british-born man of nigerian descent. they say he's a convert to islam. reports say the men were known to the internal security service mi-5 but were not considered serious threats. after announcing the arrest of the two latest suspects, police called their investigation complex and fast moving. prime minister david cameron has moved to calm fears, saying attacks by extremists would only bring the british people together.

>> we will never give in to terror or terrorism in any of its forms. >> members of british muslim groups denounced the attack as a barbaric act that has no basis in islam. >> these voices of extremism have no place in our mosques or societies. they operate in the margins, and they thrive on getting maximum attention. >> president obama released a statement condemning what he called an appalling attack. he says the u.s. stands resolute with the united kingdom against violent extremism and terror. a four-lane bridge crossing a river in the u.s. state of washington has collapsed, throwing vehicles and people into the water. local media say three people were injured. the highway bridge is located about 100 kilometers north of seattle. at least two vehicles fell into the water. no fatalities have been reported. the bridge over the river was

built in 1955. in his state of th union address in february, u.s. president obama discussed aging infrastructure. he proposed a program to repair deteriorating facilities including what he called nearly 70,000 structurally deficient bridges. let's now get the latest business stories from ron madison. ron. >> thank you very much. let's get straight into the markets this hour because the tokyo stock market did have yet another day of highly volatile trading. it did manage, though, to post a gain after thursday's sharp decline. the nikkei index ended at 14,612. that was a gain of just about 0.9%. that was also up about 128 points. it managed to rebound from a sharp selloff that it suffered in the previous session. now, the nikkei showed big swings showing gains and losses more than 1,000 points between the intraday high and low. tokyo's main benchmark opened higher rising above 15,000 at one stage after u.s. markets did not fall that much overnight.

housing sales data apparently lending a bit of support. but the nikkei did face strong selling pressure in the afternoon as the yen regained a bit of strength. at one stage the benchmark traded even below 14,000. some investors do remain cautious following two sessions of volatile trading. trading may stay unstable for a while. let's get a check and see how chinese markets have performed this week. on the mainland, the shanghai composite posted 0.5% gain on friday, almost 0.6%, 2,288. on thursday it fallen to the lowest point in a week after china's manufacturing activity declined in may. since friday last week, the benchmark has managed to go up just about 0.25%. in shanghai, it closed at 22,618. that was the lowest closing level in just about a month. worries over the future of the chinese economy continuing to weigh on sentiment. the benchmark finished lower for a fourth straight session,

extending its losses to 2% for the week. let's get insight into the chinese market. for that we're going to speak with dickie wong from kingston securities in hong kong. very good day to you, dickie. thanks for joining us. >> hi, ron. >> we saw that huge tumble in asia's markets due to the weak pmi data which showed a contraction down to a seven-month low. that's your take on the current situation, and what's your outlook now considering all that's happened? >> right. well, i think selling may go away may be true at least for the local hong kong stock market, i think. after the recent home run in april, the hang seng index has been up for more than 22,000 points. twentiy definitely the market is waiting for some kind of pullback, and this is definitely a good excuse for the market to pull back from the previous high last week, like worse than expected pmi

data and also most of the positive news like earnings reports were already reflected in the stock market. and also the overall stock market like in japan, pullback from the new high. so this is definitely a good excuse. but to me, i think in may, it may be a pullback but not a big slump because now the hang seng index is trading at 11 times four pe whereas the last five years on average it's more than 13 times. so this is a good valuation. and even for the china stock market, the shanghai composite index is trading at even lower, only nine times forward pe. so i think this is just a fullback and not a big slump in may. the hang seng index may find some kind of support at 22,300 at the short term speaking. >> dickie, thank you very much

for your insight there. dickie wong, executive director of research at kingston securities in hong kong. long-term interest rates not exempt from all the volatility that we've been seeing this week. the benchmark ten-year government bond yield rose and briefly touched the 1% level on thursday. that was the first time that's happened in more than a year. prime minister shinzo abe pledged that he'll make every effort to avoid a spike in long-term interest rates. he said on friday that massive government bond buying could affect the market, although the boj is doing it to pull the country out of deflation. he said a surge in long-term interest rates could impact people's everyday lives. so he says he wants the central bank to communicate closely with market players. >> translator: the bank of japan is only buying bonds circulating in the market. the japanese government will never force the central bank to purchase bonds and shoulder the government debt.

>> abe also said the government will work to secure market confidence by going ahead with efforts to restore fiscal health. and bank of japan governor kuroda said it is desire bible that the long-term bond market stabilizes. >> translator: the central bank aims to prevent rapid fluctuations in long-term interest rates as far as possible. by taking a flex ible approach, that is to make our bond purchases have a bigger and more appropriate impact on the economy. we have pledged to buy about $500 billion worth of bonds annually. >> kuroda said the central bank aims to achieve stabilization of the financial and capital markets through dialogue with market participants. and that is going to wrap it up for biz this hour. let's close things out with a check of the markets.

japanese leaders have welcomed reports that north korean authorities are willing to hold dialogue to ease tensions. they say they'll coordinate with their counterparts in the u.s., south korea and other nations. state-run media in china reported on a meeting between an envoy of north korean leader kim jong-un and a senior chinese communityist party official. they say the envoy expressed a

willingness to hold talks with relevant nations. japan's chief cabinet secretary, suga, says it would be a positive step if the north stopped provocative acts and moved toward dialogue. >> translator: our basic policy toward the north is dialogue and pressure. the window for talks is always open. >> suga says north korean authorities would need to take concrete action toward denuclearization to secure dialogue. levels of carbon dioxide are on the rise in japan. average density of the greenhouse gas recently exceeded the international standard and all of the country's observation points. the meteorological agency is monitoring its levels at three locations. they are ofunato city in northeastern japan, yonaguni island, and minamitorishima

southeast of tokyo. the observation data showed that in april, the monthly average level of co2 at all the monitoring sites exceeded 400 parts per million. that's the threshold set by the u.n. intergovernmental panel on climate change, or ipcc. the global average concentration of co2 is about 390 ppm. meteorological agency officials estimate that at the current rate, it will exceed 400 ppm within a few years. agency officials say average co2 density is increasing at a faster rate than in the 1990s. he is asking people to set the thermostats on their air conditioners a little higher than usual and take other measures to reduce co2 emissions. japan's national judo federation has been hit by another scandal. the all-japan judo federation is investigating alleged sexual harassment charges brought by a

female judoka against a federation director. the athlete says the director forcibly hugged and tried to kiss her in an elevator in a tokyo train station in december 2011. she says she decided to take the matter to a lawyer when the federation failed to take actn after she discussed the matter with the other directors. the chairman of the federation's public relations board announced the probe on friday. >> translator: we'll announce who was involved and what measures we'll take in the future. >> the japan olympic committee took disciplinary measures against the federation in march for the physical abuse of female athletes by national team coaches. doctors and other health care workers in rural china are overwhelmed by work. officials say that per capita,

their number amounts to less than one half of participants in city so being a country doctor is a challenge. for one petitioner, it means regarding her own health. our reporter reports. >> reporter: she practices medicine in a southwestern village. her husband drives her to patients' homes. the husband always travels with her because of her chronic leg ailment. here she visits a farming family. she is checking up on an elderly woman who can leave her bed. she visits almost every day. >> translator: i can't walk so the doctor's house calls are a tremendous help. i'm so grateful.

>> translator: it's not easy traveling all the way here. but when i see the villagers' smiling faces, it feels worthwhile. >> reporter: about 3,000 people live in the village of xihe. two of every three residents here are in their 60s or older. so a lot of them find they need more medical treatment. she's been the village's only doctor for more than 20 years. after acquiring her doctor's license, she returned to her home village to open a clinic. when she was 8 months old, a congenital illness caused her left leg to become paralyzed. at the time, the village had no hospital or clinic. so her parents carried her on their backs to a hospital in a

neighboring town. >> translator: i didn't want anyone to go through what i experienced. that's why i decided to become a doctor. i want to treat people in this village who have disabilities or illnesses. >> reporter: the endless days of work are taking their toll on her body. she needs medical care herself. her husband worries about her health. >> translator: as my wife gets older, she gets more tired. of course i worry about her strength. i do whatever i can to support her. >> reporter: recently she had to stay in hospital for a month to receive treatment for her leg. the victimllage couldn't find a

doctor to fill in for her. she went back to work the day after she was discharged from the hospital. locals worry that without her, they would lose their medical service. >> translator: doctors wouldn't come here because of the low wages and poor working conditions. i'm asking the government to do more for the health care of rural villagers. >> translator: i feel rejuvenated when i see my patients smile. i'm determined to continue working for people here. >> reporter: all the residents count on the dedication of just one doctor. but someone like her might not always be there to help them. it illustrates the need for

authorities to take action to improve the situation in rural areas. >> we spoke with mr. yamamoto and asked him if villages with only one doctor are common in china. >> it's basically the norm. a survey shows that as of last year in the countryside, there were 1.3 doctors for every 1,000 residents. in fact, some have no doctor at all. but in cities, there are three doctors for every 1,000 residents. also, it's very evident there is a trend among medical students to avoid setting up a practice in farming villages. the med students are entitled to choose which hospital to work for when they graduate. so many are for facilities in urban areas. that's no surprise. after all, working conditions are better there, and a promising career path awaits them. as for persuading more doctors and nurses to relocate to remote

villages, the government hasn't had much success. china's medical system needs a major reform. >> let's now bring in robert speta for a check of the weather. robert, it's a beautiful friday here in japan. will conditions stay like this over the weekend? >> well, shery, it does look like thankfully most of the weekend across japan, that is, fair weather will be overhead. temperatures throughout the 20s here. it will cool off in tokyo down to about 20 on saturday. it's going to rebound going into sunday as this high pressure continues to dominate. not just japan. the korean peninsula as well. much of central and eastern china, on the other hand, you're not going to be sharing in on this. right now southeastern china's getting a break from the action. you can see that cloud cover coming out of the west. that is the next low-pressure area that first will affect chongqing on friday. then it's going to push off towards the northeast and bring about 250 millimeters of rainfall as well over towards shanghai. much of central and north eastern china.

so this is going to be bringing the risk of flooding and even landslides as it continues to push overhead. even the tail end will develop showers near coastal areas towards the south. we want to continue to watch that. by next week very well could affect much of mainland japan. for now, like i said, partly cloudy skies across much of the region. don't be surprised if you do see an isolated thunderstorm pop up here, especially due to the afternoon and daytime heating but nothing at all widespread. let's take a look over toward the americas. widespread showers for the memorial day weekend across much of new england. if you have any barbecue plans out here towards the northeast or you're going out to any of the festivals or parades, well, unfortunately, it's going to be some showers on tap for you. behind it into the great lakes region, much fairer weather. the thing here is that it's going to be colder because this high pressure's coming in all the way from northern canada, bringing all that cold air with it. actually some frost warnings across much of michigan over towards wisconsin, especially away from the great lakes. once again into these inland areas and higher elevations, you

could see a little bit of the white stuff on the ground when you wake up in the morning. it definitely will melt off by the later morning hours. but really that's going to continue to extend to the south. that's interacting with warm air out of the gulf of mexico. what we'll be seeing across much of northern texas and western oklahoma, yet again, we're going to be seeing yet more rain showers and the risk of some severe thunderstorms coming out of this. yesterday we had two reports of tornadoes there in central texas. and that threat is going to continue to pop up here throughout your day on friday. but the main threat is going to be damaging winds possibly around 90 to 100 kilometers per hour and even large hail. farther towards the northwest, things cooling off in the pacific northwest. even mountain snow in your forecast there. 16 for you in vancouver. and also as well as seattle. let's take a look towards europe. really the main topic here is three different low-pressure areas we are continuing to watch. rotating around the center mass there in central europe. let's first talk about the east. in eastern europe, we're continuing to watch around the

baltic states some heavy rain showers, severe winds continue to push out of that. that's going to continue to charge off towards the east. farther towards the south, even in the alpine regions, you have actually some heavy snowfall warnings in effect. very winterlike indeed. low-lying areas going to be seeing heavy showers. that snow will be on top of some of the mountains. the other system that's going to be bringing foul weather is across the uk and france pulling in moisture out of north atlantic. some of these could cause localized flooding. very chilly. in london, on friday, just nine degrees. it does not feel like late may. we'll have high pressure come in from the west. take a look at sunday. starting to get back up towards average. that is a look at your world weather. here's the extended forecast.

and that's all for this hour. i'm shery ahn. thank you for watching.
