scientists have remodeled this and they are saying that the prevailing currents could have taken the debris all wait to reunion island some 4,000 kilometers to the northwest and just off the east coast of mad madagascar. >> for 17 months families of the passengers and crew aboard malaysia airlines flight 370 worried and cried over an airliner that disappeared without a trace. but finally confirmation that a piece of wreckage did come from that flight. >> today, 515 days since the plane dills disappeared it is with a very heavy heart that i must tell you that an international team of experts has conclusively confirmed that the aircraft

debris found on reunion island is from mh 370. >> the part washed up on the island of reunion in the indian ocean last week. the piece want sent to the french military aviation operation where authorities also looked at it. in the expert's view, there are strong presumptionings that the flapron found belonged to mh 370 for two reasons. boeing representatives confirmed that it came from a boeing 777. on that basis it was possible to establish a link. >> families knew there would be a high chance the part would be from mh 370. before the announcement was made, some said the discovery would not bring closure.

>> one piece doesn't mean the plane has been fully discovered. there must be more debris to be found. one piece is not enough at all. >> it's not the end of it. they found something it's not the end. they need to find the whole thing. yes, we still want them back. >> delivering on the wish to find the whole aircraft will be difficult. a six week air search found nothing. even if more parts wash up, getting definitive answers could prove impossible. china suffered the biggest loss of people when mh 370 went missing. relatives of the missing say not enough has been done to find out what happened. 153 people are believed chinese nationals were on board. pretty early days at the moment in terms of this investigation. it is promising. but you can understand why

there's been so much mixed reaction from the chinese. >> reporter: yes, if you thought this latest development would offer a slender shred of comfort to help bring closures to these families, i'm afraid you are wrong. they are still scathing about malaysian airlines, they don't believe anything its officials have said so far. some of the families i into he can to today who have been protesting outside the beijing offices of malaysian airlines say they believe that the wreckage that was found on reunion island was planted there. that may seem fanciful, but their emotions have swung from hope to despair. it's the hope that continues to get them down. so they have become hostage to these fanciful notionings. let's listen to what some of the

families had to say to me a short time ago. >> translator: it's not true. a lot of things would have been easy to find, but they didn't find them. like the chairs, baggage other stuff that's much lighter. >> translator: during this time we cannot believe anything. because the aircraft has gps. the airline doesn't want us to know the truth. that's why we can't believe them. >> very distressing to watch that. what's being made of the way this announcement, this confirmation has been handled because the french and dga are not giving official confirmation, they have further visions today and malaysia said this is it, this is part of the plane. >> reporter: yes, the french have been much more cautious, as you say in their response. some of the families wonder why the malaysian airline officials and malaysian government have

been so category cal in their judgment. they don't dispute this is the wreckage. they think it was planted there. on the issue of come peppization, many of the families i spoke to they are refusing to accept the interim payment of $50,000. to do that is to accept their loved ones are dead, not coming back and they can't do that at the moment. >> we'll leave it there for now. thank you very much. as many as 200 people are feared drowned after a boat capsized in the mediterranean sea. 25 bodies have been recovered so far. the u.n. refugee agency says about 400 people were rescued. gerald tan has the story. >> reporter: a family reaches safety. this one-year-old girl was taken on to a rescue boat where

medical teams are standing by. the trauma is etched on her face. she was among hundreds of migrants packed on a fishing boat which had capsized. it issued a distress call less than 30 kilometers off the libyan coast. rescuers from the italian coast guard, the irish navy and medical charity doctors without borders, arrived to see the striken boat overturned. they rushed to one side of the boat causing it to capsize. what followed was a furious search and rescue operation. helicopters and ships joined in. they have saved hundreds of people and also recovered many bodies. it's unclear exactly how many people were on board the overloaded boat. but it is clear what drove their decision to get on. >> what's important is to understand that there are no other roots for these people to

take to flee from the conflicts from the violence they are fleeing from. it's 60% of the people making this treacherous journey across the mediterranean fleeing from afghanistan, syria sew somalia. they have no safe roots to do this. they are risking life and limb to make this voyage. >> more than 2,000 have died attempting to reach europe by boat. as rescuers comb the waters for survivors, they know this won't be the last time. gerald tan, al jazeera. in yemen pro government forces have expanded their strong hold in the south. it comes a day after pro government forces took control of the provinces from houthi rebels. they are pushing north.

netanyahu disagrees. i do not doubt his sincerity. but i believe he is wrong. >> reporter: the president warned if congress blocks u.s. sanctions from being lifted, it could lead to war with iran. those opposed were the ones that pushed for the war in iraq. now he's making a new argument, an economic one. >> we have to cut off countries like china. since they are major purchasers of our debt, such actions can trigger severe disruptions in our own economy and by the way raise questions internationally about the dollar's role as the world's reserve currency. >> they dispatched the head of the iaea to brief the senate. it didn't change the mind of one of the key critics. >> i would say most members left here with greater concerns about

the inspection regime than they came in with. >> reporter: the key to getting support is convincing the majority of their voters they need to make their voices heard. the student whose watched the speech, all said he convinced them. but he has to do more than that. he needs them to act. >> there is a facebook group for americans that's au against the iran deal. i think i might set off. >> i will send a small e-mail. >> now the fight is on for e-mails and phone calls. not yet ringing off the hook for all members on capitol hill. >> thank you very much. >> both leaders know if they are going to win that has to change and in their favor. still to come on al jazeera it's one year ago now until the

370. as many as 200 migrants are feared drowned off an overcrowded fishing boat. 25 bodies have been recovered. about 400 people have been rescued. u.s. president is appealing to americans to back the iran nuclear deal saying that without it, there will be war in the middle east. mr. obama has been presenting his case at the american university. japan is marking the grim anniversary of 70 years since the hiroshima atomic bombing. 55,000 people, including representatives from a hundred countries observed a moment of silence at the historic hiroshima peace memorial park. the bomb dropped by the united states in 1945 killed tens of thousands of people and changed the face of global warfare.

jeffrey kingston is the director of asian studies at temple university and joins me live via skype from japan. thank you for joining us here on al jazeera. let's talk through the event itself and the significance of it remembering 70 years on. >> well, annually, they will have a commemoration ceremony about this being the 70th year. as the atomic bomb survivors are the average age is 80, i think that the event this year was a little bit more important, a little more poignant than it has been in recent years. august 6 reinforces japanese deep sense of passivist passivism. that's why the mayor and prime

minister abe invited world leaders to visit hiroshima nagasaki to they can see what's at stake as they lobby for nuclear disarmament. >> we did hear mr. abe vowing to redouble japan's efforts to halt nuclear proliferation. as you say japan's commitment to passivism is about to change if this new security law is accepted. >> yes. prime minister abe has been cratering in public opinion polls because he's been trying to get through legislation that most japanese people oppose. so a lot of people feel that he is in a sense undermining the passivist national identity. he's undermining the constitution.

constitutional scholars are unanimous that the new bills are unconstitutional. so the optics have been bad for prime minister abe. he views the occasion of the speech to remind people that he is also opposed to war. but i don't think a lot of people believe that. i think a lot of people are very much worried about where abe is leading the nation. and building closer security relationship with the united states somehow somewhere japan will be dragged into a war at washington's behest. that explains why there is such a strong backlash. >> i want to pick up on this point. do many japanese recognize the point that the country's security needs have changed somewhat to what was taking place 70 years ago and why pass i havismipassivism was put into place.

the major risk is events taking place with china. >> yeah, that's the case that abe has been trying to make to the japanese people. not only in the parliamentary enter prelocations, but also doing a full court press with the mass media. he hasn't convinced people that this legislation is the answer to japan's problems. one of the problems is that the legislation is vague. there are few constraints little oversight. a lot of discretionary authority is given to the prime minister. i think a lot of people may recognize the new threat environment in asia and it's a dangerous neighborhood. at the same time, they have deep reservations about this particular legislation because it's not very detailed and they are concerned that another government in the future might not use these powers responsibly. >> okay. jeffrey kingston speaking to us

from japan. thank you. >> thank you. more help is arriving after the government appealed for assistance. landslides cyclones have killed 74 so far. relief teams have been struggling to reach remote area areas. we have lost that. when we get it, we'll get it to you. let's turn our attention to the northeast of nigeria where attacks by boko haram is hurting farmers. the armed group imposes its version of islamic law. >> reporter: earning a living as a farm hand, less than $2 a day working on someone else's farm.

hoping for answers. >> reporter: for 21 years he has been frying to find out who killed his son. >> translator: every day i'm with hatred and ask myself why. who was behind the bombing. somebody has to be responsible. >> reporter: he died on july 18 1994 in an attack against a you're community center in argentina. 85 people were killed and hundreds of others injured. it was argentina's deadliest attack and the authorities were clear calling it terrorism. until now no suspects have been convicted for the attack against this jewish community center 21 years ago. even though the government has accused people from being behind the bombing who did it locally has been filled with incompetence and accusations of

cover up. >> reporter: now they will stand trial for allegedly corrupting the investigation. they have been researching the attack for years and says that the argentina state is responsible for covering up what is known here as the local connection. >> translator: this attack was not possible without the help of the local police or intelligence services. >> reporter: iran has always denied its involvement. last year the prosecutor accused the president of changing the government strategy and conspiring to cover up a probe on iran's involvement in the attack. on the day he was to present his results he was found dead. >> it ends after the explosion. but the real wave ends up when you put behind bars those

responsible. it continues because nobody knows what happened. i believe he died because of that. [siren] >> reporter: even though the trial was supposed to begin in february. they urged the judiciary to speed up the process. some say an attempt to show the results before presidential elections. people are thankful. he believes that this trial could bring him closer to the truth. back to rio de janeiro where the countdown has started for next summer's owe licks. the projects are all on schedule and rio will be ready to host one of the biggest sporting events. >> reporter: the clock is ticking. olympic authorities seem satisfied. the 2016 olympic games in rio de janeiro will start august 5
