will be a historic moment. the e.u. high representative made the announcement with the foreign minister. details of how iran's nuclear programme will be restricted over a 25-year period. the sentry finaling cut from 90,000 to 6,000. >> the stockpile will be limited for specific durations, and there'll be no other enrichment facility. and this is the fate of the once secret bunker built inside a mountain. >> it will be converted from an enrichment site to nuclear physics and technology center. >> does this count as a framework agreement the white house promised by the missed deadline of end of march. iran's minister insists that nop of it is bind -- none of it is

binding. >> no agreement has been reached. we do not have an obligation yet. >> 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. >> the secretary of state spent more time on this than any other issue. the negotiation process cap already be judged. >> it's important to note na iran to date honoured the commitments that it made under the joint plan of action that we agreed to in 2013. i ask you to think about that against the back drop of those who predicted that it would fail and not get the job done. >> nuclear talks will continue with tough bargaining between now and the final deadline at the end of june. this is an important milestone,

and not just on the nuclear issue. iran and western leaders may be beginning to build a new relationship after 36 years of mistrust and hostility. simon mcgregor-wood has the latest from lausanne. >> it's a general sense in lausanne that late on thursday night, that the side succeeded in concluding a significant deal. we had to remember that only 24 hours ago the mood here was negative. people were hearing that failure was not ruled out. everyone is surprised that in the end, the parties were able to conclude not just a broad vague framework of understandings, which we were warned we might get, but something more than that. there was detail in the agreement, there was numbers. we talked about the number of centrifuges going down to

specific numbers and percentages of iranian enrichment. all sorts of interesting frameworks of numbers of years, regimes that had to be in place. lots of details to be worked out between now and june 30th when it had to be codified and a lot can go wrong between now and then. this is a better deal than people expected 24 hours ago. i think it will be important for the americans and president obama, who need a good deal to confront the skeptics if you line in congress who have been unhappy with the process, and are threatening to come back and try to impose new sanctions on iran. this agreement gives president obama ammunition to persuade them not to do that. >> the united states is heralding the deal with iran, but the agreement in switzerland is the start of the process. it may be harder for president obama to convince congress about

the potential benefits. the white house correspondent has that story. >> u.s. president obama was supposed to talk about the economy in kentucky. he delayed his trip wanting to make sure the american people heard his perspective on the nuclear deal first. >> i'm convinced that if the framework leads to an extensive deal it will make our county really lies and world safer. >> he believes he can make the deal on his own. many in congress disagrees. senator bob corker says he'll bring up a bill forcing the president to get their approval writing: right now it's not clear that the president has enough support that they will be able to

override a veto in cop cess. he's making a case to the government. >> if congress kills the deal not based on analysis and not offering alternatives the united states will be blamed for the failure of diplomacy. international unity will collapse, and the path will widen. >> those in favour rules out the president has public opinion on his side. >> a lot of polls suggest americans support talks, they are not confident that a deal will be effective. >> the president expressed the same cynicism but argues he needs to give diplomacy a chance. it's not clear that the u.s. congress will let him. >> israeli prime minister binyamin netanyahu condemned the agreement saying a deal based on the framework threatens the survival of israel. imtiaz tyab has been following

the developments from west jerusalem. >> israeli prime minister binyamin netanyahu has been the fiercest critic about the negotiations between western powers and iran trying to make this agreement that they have now reached, to move forward. mr binyamin netanyahu has consistently 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 palay made his statement after the agreement was announced, that he spoke at length about israel's concern. while he and binyamin netanyahu don't see eye to eye on this issue, that he reaffirmed the u.s.'s commitments to israel's security. whatever the case mr binyamin netanyahu again, as we have been saying has been a fears critic

of any nuclear deal with iran and says a deal with iran not only threatens israel but the middle east and as he put it, the rest of the world as well. >> there has been celebrations in the streets of tehran in support of the agreement. people cheered for the president, and the prospect of sanctions being lifted. years of international embargoes hurt every spect of the economy. >> kenya's interior americans says 147 people have been killed of al-shabab gunmen stormed the juste campus on thursday. government officials say all four were tilled. i there's now an overnight curfew. kenyan troops tried to flush out al-shabab fighters holed up inside the college. the attackers stormed the

[ siren ] >> it is close to the border. the ken yen army has been in somalia since 2011. al-shabab, a group linked to al qaeda, says they must leave. many were taken hostage, others escaped. the university is about 100 metres down there. gunfire is going on for hours. we are told the attackers are on the roof took place, and the upper floors. that's making it difficult for the soldiers to fight them out of there. >> meanwhile soldiers tried to keep bystanders and journalists away. >> i'm malcolm webb. a journalist. we managed to get the number of a hostage hidden inside.

she was hidden with five friends. >> it was hard to hear what she was saying but easy to hear the terror in her voice. she said she had to be quiet, and hung up. nearby in the hospital pain grief and horror. >> the government had been worned the university was a -- warned the university was a vulnerable target. attacks led many to question why nothing was done. measures are taken now. >> i, the inspector general of the national police do hereby issue curfew orders in the counties of garissa and others. >> reporter: but for the families of the dead students it's too late. kenyans, once again, have to come to terms with the loss of so many.
