moment. the e.u. high representative made the announcement with the iranian foreign minister, details of how iran's nuclear program will be restricted in phases over a 25-year period. it's centrifuges cut from 19,000 to 6,000 limiting to one facility. >> iran's enrichment capacity, enrichment level and stockpile will be limited for specific durations. and there will be no other enrichment facility. >> reporter: and this the fate of the once secret bunker built inside a mountain. >> it will be converted from an enrichment site in to a nuclear physics and technology center. >> reporter: so does this count as the framework agreement the white house had promised by the missed deadline of the end of march? iran's foreign minister insists for now, none of it is binding. >> no agreement has been reached. we do not have any obligation

yet. >> reporter: but he added this. >> we didn't put all of this time and energy and many sleepless nights to write a piece of paper hopefully by june 30th, that we are going to just look for an excuse to violate and abandon. >> reporter: the u.s. secretary of state has spent more time on this than any other issue. john kerry says the negotiation process can already be judged. >> it is important to note that iran to date, has honored all of the commitments that it made under the joint plan of action, that we agreed to in 2013. and i ask you to think about that against the backdrop of those who predicted that it would fail and not get the job done. >> reporter: nuclear talks will continue with tough bargaining between now and the final deadline at the end of june. but this is an important milestone and not just on the

nuclear issue. iran and western leaders may just be beginning to build a new relationship after 36 years of mistrust and hostility. james bays, al jazerra lausanne. and simon mcgregor wood has the latest from lausanne. >> reporter: the general sense here in lausanne late on thursday night is that the sides succeeded in concluding a significant deal. we have to remember that only 24 hours ago the mood here was very negative and people were saying, including the german foreign minister was that failure was not being ruled out as a distinct possibility. but i think that everyone is surprised that in the end the parties were able to conclude not just a broad vague framework of understandings, which we are being warned we might get but something a bit more than that. there was detail in this agreement. there was numbers we talked about the specific number of centrifuges going down to very specific numbers very specific percentages.

of iranian enrichment, all sorts of interesting frameworks of the number of years certain regimes of inspection would have to be in place clearly there are lots of details to be worked out between now and june 30th when all this has to be codified in minute detail and a lot can go wrong between now and then. but i think this is a better deal than people were expecting only 24 hours ago. and i think that will be particularly important for the americans, particularly for president obama who needs a good deal to confront the skeptics if you like, in congress, who all along have been unhappy with this process and are threatening to come back and try to impose new sanction on his iran. i think this agreement gives president obama some ammunition to try to persuade them not to do that. the united states is harolding the deal with iran, but the agreement is switzerland is just the start of the process. it may be harder for president obama to to convince a hostile congress about the potential

benefits. our white sox correspond end he want patty culhane has that story. >> reporter: president obama was supposed to be talking about the economy in kentucky, but he delayed his trip for hours wanting to make sure the american people heard his perspective on the deal first. >> i am convinced if this leads to a comprehensive deal it, will make our country our allies and our world safer. >> reporter: he believes he can make the deal on his own. many in congress disagree. republican senator bob corker says he will bring up a bill to force the president to get their approval in two weeks. writing, rather than bypass congress and head straight to the u.n. security council as plans the administration should first seek the input of the american people. there is growing bipartisan support for congressional review of the deal and i am confident i've strong vote. >> reporter: right now it's not at all clear that the president has enough support from members of his own party that we they won't be over to over ride a

veto in congress. he's make ago case to the american public, arguing if congress kills this deal, the only other option is war. >> if congress kills this deals not based on expert analysis and without offering any reasonable alternative. then it's the united states that will be blamed for the failure of diplomacy. international unity will collapse and the path to conflict will widen. >> reporter: those in favor of the deal point out that the president has public opinion on his side. >> a lot of polling suggests that they are not necessarily confident that i deal is going to be it. >> reporter: the president expressed the same cynicism but argues that he needs to give diplomacy a chance, but it's not yet clear if the u.s. congress will let him. patty culhane, al jazerra washington. israelii prime minister benjamin netanyahu has condemned the agreement. he says a deal base on the framework threatened the survival of israel. following the latest developments from west

jerusalem. >> reporter: israeli prime minister benjamin netanyahu has wents fiercest critic about these negotiations between western powers and iran trying to make this agreement that they have now reached to move forward. mr. netanyahu has consistency said that any kind of deal or agreement needs to involve a major, as he put it, roll back of iran's nuclear ambition. and it's quite telling that when president obama made his statement after the agreement was announced that he spoke at length about israel and israel's concern. mr. obama said that while he and mr. netanyahu don't see eye to eye on this issue that he reaffirmed the u.s.' commitment to israel's security. whatever the case, mr. netanyahu again as we have been saying has been a very fierce critic of any kind of nuclear deal with iran.

has been taken what's been going on? >> reporter: well, there is great excitement here in the very far east of indonesia. the investigation team from the indonesian government has just announced to this group of people from myanmar the people from myanmar right here and also others from cambodia and some thailand lay owes, can go home. they are going bring them on safety from ghost pwo*ets from the government because they are worried that they are not safe higher anymore. they have been speaking to journalists and also the government team. horrific stories of abuse and also about their working conditions. some of them here have been working for many years on these boats, many long hours days of work and no rest. they were not allowed to sleep they have hardly any food, and worse they were not even paid. they get some hand outs after a couple of months on the boat. they got just some pocket money but no proper salary. so you can imagine the excitement here now that they have heard that they can go home.

the government will take them very shortly now on these boats. they have divided them in groups this group is from cambodia. they have now just decided that it's time to go home and many have been want this is for many, many years they told us that they were so happy so relieved. there were actually real reports of slavery. the government has told me just now that after talking to these people they can conclude that there were cases of slavery here forced labor. people here didn't even know that they were ending up here in the east of indonesia, they were looking for jobs in thailand. they contacted an agent in myanmar, they were brought to thailand, they thought they were going to work in restaurants but then they were shipped to indonesia and ended up in this very tough fishery business. so the first thing they want to do when they are going to go home is to meet their family. they have been missing them so much. and they are bringing their belongings, you can see sorry. you can see here, how they are bringing their bags, this is all the they got. this is all that they have been gathering in the last couple of
