today we have reached a critical milestone. >> agreement in switzerland. the u.s. and other world powers finally come to terms on iran's nuclear program. attack in kenya. al shabaab gunmen storm a university targeting christians and turning it into a killing field slaughtering at least 147 people. a ghost town in iraq. >> we want officials to tell us to get back to our homes or not. >> sunni residents want to

return home to a city battered and bruised by isil and 33 years after their war in the south atlantic. >> i still hope to one day set foot on what should be our territory. >> britain and argentina are still bickering of the falkland ulklandlkland s -- the eu 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. its centrifuges cut from 19,000 to 6,000 and limited to one facility. >> iran's enrichment capacity enrichment level, and stock pile 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 become converted from an enrichment site into 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, so 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. al jazeera, lausanne. >> our senior washington correspondent joins us now. the president came out, praised the framework deal. why does hand ball this will work? >>reporter: two principle reasons, antonio. number one is breakout time. limiting the uranium stock piles

iran has and its able to to enrich uranium with centrifuges. so if iran suddenly decided to build a bomb it would take them at least a year to do so and give the international community time to develop a response. the second thing is inspections with the white house and again outside experts are saying unprecedented inspections, intrusive inspections. this would stop iran presumably hopefully, from going the secret coverity route from trying to build a bomb. they're going to have so much leeway inside a ran that that is unlikely to happen. >> one question of course mike is what will congress do. they have threatened to add sanctions if a deal wasn't reach. how are members reacting to the deal? >>reporter: well that's the first thing they're focusing on. you mentioned at the top, john boehner also wanting to take a look at the sanctions. how quickly they're removed or

the benchmarked by which they would be removed. congress really isn't going to have a say so on lifting sanctions. it's built into the law that the president can have a waiver of the sanctions and the president has signalled he intends to do that. but it's not out of the question that congress would try to impose even more sanctions. also as soon as congress gets back from its recess on april 14th they're likely to take up a bill that would give congress the accept or reject this deal. the president has said he's going to veto that. but he's part of the argument the president made this afternoon today in washington in the rose garden. >> this framework would cut off every pathway iran could take to develop a nuclear weapon. iran will face strict limitations on its program and iran has also agreed to the most robust and intrusive inspections and transparency regime ever negotiated for any nuclear program in history.

>> the president went on the say that if congress kills this or tries to kill this the united states is going to lose face in front of the middle east and its allies. >> on the other hand some of our main allies are not happy about this. the president had to do international outreach today. >>reporter: that's right. one of the first calls he made was to the king of saudi arabia and perhaps to calm some of the anxiety the saudi arabiaens are feeling. he also talked to america's more traditional allies france germany, the u.k. and then on his way to a much delayed event in kentucky this afternoon, finally making that call to benjamin netanyahu. the white house insists there's

no daylight between these countries in terms of the long term arrangement and security between the united states and israel we reached out again to the former head of the iaea for reaction to the nuclear talks. he says he's hopeful an agreement has been reached. we asked him if he bes israel's concerns over iran are well founded. >> i can understand them and i can understand their resentment of the statements which were made and which -- also the lead leading ayatolla expresses. at the same time my feeling has always been he was speaking more to arab countries and not

ayatollah. >>reporter: this deal reduces the number iran can run to around 6,000. iran is also not allowed to enrich uranium above a concentration of 3.67% for at least 15 years. the iaea says iran is already limiting its production of

reactive grade fuel for its power plant. but there are concerns iran has kept some of its nuclear activities hidden. this is why the access given inspectors is so important. if iran breaches the agreement, the world wants to have enough time to react. >> here now to discuss the deal is iran's lead negotiator during nuclear talks a decade ago. he's now a research scholar with princeton university. you were part of these negotiations. you were the lead negotiator 12 years ago. why did this deal work now when that one did not? is it all because of more moderates in power in iran? >> actually during 2003 to 2005, the current president was the top nuclear negotiator

and -- key negotiators. today is the same. therefore, that time it was the president. today is a moderate. i think the only reason that made the deal possible was a change in u.s. position. during 2003 to 2005 we were ready to have the same principles agreed today in lieu san but the u.s. was insisting zero enrichment in iran no single centrifuge in iran. >> so you think the u.s. has moderated its position. >> is u.s. moderator agreed principally to it. >> and enrichment was an important part of the conversation. president obama gave his speech today, it was actually broadcast live in iran which has never

happened to be so i assume that's a good sign. he said as we just heard this cuts off every pathway to a bomb. but is that true? because critics in israel and the u.s. say it's not and part of it is because they say that iran is keeping enrichment facilities beyond what they need for peaceful nuclear energy. >> i think president is correct because you have only two ways to make nuclear bombs. one way is from heavy water facility. in heavy water facility if you do not have reprocessing facility it's impossible to make nuclear bombs. >> to get it to weapons grade. >> exactly. the second is making nuclear bomb from enrichment. to have that you need to enrich to above 90%. as long as you enrich below 5% there will never be a risk of proliferation from enrichment

facility. >> the president also said that if iran cheats the world will know it. >> to bring confidence the iranians have accepted the maximum level of transparency in the history of proliferation. >> and you think they'll follow through with that? >> they are fully commitmented after the joint plan of action agreed november 2014. they have no failure during the year and a half. i believe they will be fully commitmented. >> quick final question the foreign minister seemed very happy, almost exuberant about the deal. i would be nervous that i cut a bad deal. >> i believe everybody was happy today. john kerry was very happy.

the other foreign ministers from p5+1 were very happy. president obama was very happy. iranian foreign minister was happy. i believe american nation they are happy because 60% of americans wanted a peaceful nuclear deal. >> and i know you have said that you believe this deal will make iran less aggressive. it's very good to have you with us. thank you very much. >> thank you as i mentioned, some iranians have been celebrating hoping this means a quick end to economic sanctions. coming up this evening we'll have a closer look inside the country from an iranian journalist. kenyan authorities say they have now accounted for all the survivors of a massacre after gunman from the somali terror group al shabaab rampaged through a university campus. a wanted poster was issued for the suspected master mind of today's attack.

police say at least 147 people mostly students were killed. >>reporter: it was supposed to be a place of learning but instead became a battle ground. kenyan troops tried to flush out al shabaab fighters holed up inside garissa university college. they stormed the building in the morning while students were sleeping. security forces were deployed. garissa is close to kenya's border with somolia and has been targeted before by al shabaab an al quaeda linked group. >>reporter: many of the injured

suffered gunshot wounds an inside the hospital where they were treated, pain grief, and horror. [screaming]. >> they started shooting. there was one gunman firing from the doorway so i had to jump out of the window and that's when i was hit by a bullet in the leg. >>reporter: this attack will undoubtedly lead to questions about whether enough security was being provided at the university. >> 90% of the threat is eliminated as i speak to you now. at a cost. a very very heavy cost with regard to human life lost. as it stands now, we are able to rescue over 500 students. >>reporter: a dusk until dawn curfew is now in place in

garissa. kenyans once again are trying to come to terms with the loss of so many. 'em ma hayward, al jazeera the obama administration is condemning the attack in kenya. the secretary of state issued statements offering condolences saying the united states stands with the people of kenya and that the u.s. will continue to work with kenya to end terror attacks in the east african country. president obama is scheduled to travel to kenya later this year al shabaab, the group behind today's attack in kenya. coming up who are they and how big a threat to they pose and later, iraqis venture back to their battered neighborhoods near tikrit. hoods near tikrit.

kenya's president tonight is urging kenyans to remain calm as government forces confront terrorism on its soil. the attack on garissa university today is the deadliest in kenya

since the 1998 al quaeda bombing at the u.s. embassy that killed more than 200 people. al shabaab has claimed responsibility for thursday's attack on the university. thomas drivewayton takes a closer look at the armed ayton takes a closer look at the armed group. >>reporter: al shabaab con yours up something terrifying. conjure -- in december 2013, al shabaab killed 65 people in the west gate shopping center. in 2012 the group pledged ali

allegiance to al quaeda. the.com faith of saudi arabia and is a branch of sunni islam. u.n. backed forces have managed to drive al shabaab out of most urban areas but it's estimated 7 to 9,000 fighters are still active in somolia's country side and on its border with kenya. al shabaab rose to power amid the chaos caused by somolia's 20-year civil war. the east african nation has not had a functioning national government for more than two decades and al shabaab gained support in part from people promising security. but the group has brutalize people including stoning women accused of adultery and cutting off the hands of accused thieves. they also recruit foreign fighters and even children as

young as 10 to join its ranks. the director of youth point africa joins us from london. very good to have you with us. al shabaab's leader was killed in a drone strike in september. the group has had serious internal divisions and both the kenyan and somali armed forces have made advances against them. >> it shows that the terrorist group is very desperate.

it's hitting softer targets.

>> within the past week a siege and a massacre at a hotel in moeing i didgadishu mogadishu. >>reporter: the group at its weakest is at its most dangerous. the group can attack and show it has great capabilities. and we know already that the al shabaab movement has been weakened because it's severed relationships with al quaeda. that relationship is not ongoing. and more than likely this group will want to make a closer relationship with isil.

i think the worry here is that all these groups smaller groups be it boko haram in nigeria, the al shabaab movement or smaller movements across west africa is that they would start working together. that would be the worry. and isil provides that umbrella for them to do so. and of course a united strength would pose huge problems across the african continents for which we are already seeing the ripples of that. >> how deeply involved is the united states in the effort to fight and eradicate al shabaab and does the international community need to be more involved? >> the united states has always been the forefront of all the intelligence that cuts across africa in terms of dealing with groups like these.

after a week of war in yemen, houthi rebels score a victory. >> it's a shame for those in power right now. and two weeks after the brutal public mob murder of a woman in afghanistan, some soul searching. searching.

welcome back to al jazeera america. the role of the u.s. in the conflict in yemen deepened thursday. an agreement calls for american military planes to refuel saudi jets that are bombing houthi fighters. u.s. surveillance planes were

already providing intelligence to the saudi coalition. meanwhile a day of advances for the opponents. houthi fighters reportedly gained control of the city center in aden. this video shows rebels on the top of the presidential palace there. gunmen have arrived by sea. saudi arabia controls that waterway but denies the soldiers are there >> we don't have troops in aden. the issue of using ground troops is always something that's on the table but the decisions will be made depending on the circumstances and the need. >> saudi arabia suffered its first casualty since beginning its assault on yemeni rebels a week ago. they say houthis attacked their border killing one guard and wounding five others an al quaeda leader and hundreds of others were freed in a prison break today. yemeni officials say fighters from al quaeda in the arabian

peninsula stormed the prison early thursday to set the men free. a top commander of al quaeda was arrested in 2011 and was freed. thousands of yemenis have either fled or are hiding in their streets. the capital is essentially in lockdown making live difficult for businesses. >>reporter: a food store open for business is a rare sight in a city under bombardment. the war in yemen has not only forced people to flee their homes but has also made many businesses shut their doors. >> there are very few people left here. everyone has fled and those who have stayed live alone without their families. so hardly anyone comes to buy anything anymore. >>reporter: what makes things more difficult is his shop is not far from the airport and a military air base.

prime targets in saudi-led air strikes against houthi fighters who currently control the capital. in yemen, almost 1 million children under the age of five are malnourished and the world food program says 13 million yemenis rely on dirty or polluted water for drinking. >> there's no doubt that this war has gravely affected yemenis. even though food and other products are available, the average yemeni can no longer afford to buy most things. add to that the fact that many families are now displaced. it's making poverty and unemployment rise drastically. >>reporter: he finally has a customer but he only buys a bottle of war. now i'm lucky if a make $20 a day. how can i pay my rent or electric bill? if the situation stays like that i'm sure i'll be out of business in days. >>reporter: every day is a

battle here for survival. a major set back today for syria's al assad. syrian rebels seized control of theed border crossing with jordan. it's a crucial supply route for syria's military and is also a major commercial artery used by traders from syria, jordan, and lebanon so it could impact the region. it will likely clear the way for the syrian rebels to take over more government positions. tunisia wants help tracking thousands of its citizens who may be fighting in iraq and syria. the tunisian government says -- other syrian rebels. leaders in tunis say a constitutionconsulate

will help with that >> last month government forces and shia forces reclaimed the city from isil but many of the sunni residents forced to flee during the conflict are now pointing fingers at shia militiamen accusing them of abuse. >>reporter: birds singing are the only sounds of life in

. >> are there hidden agendas about the time? we want officials to tell us if we can get back to our homes or not. we want answers. >>reporter: both the shiite militias and iraqi security forces we've spoken to say isil is to blame. >> it is isil who blew up these houses before leaving. >> we are calling on the families to return and we're waiting for them to help. >>reporter: when military operations began in neighboring tikrit those still left in

al-dor fled the violence. it may now be safe to return but they still fear the militias controlling their city. a peaceful political rally was rocked by a suicide blast in afghanistan today. this was the scene in the east of afghanistan. at least 16 people were killed and 40 others injured. the demonstrators were calling for the removal of a local governor. the president of afghanistan condemned the attack calling it a cowardly attack meanwhile, the president met thursday with the family members of a woman killed by a mob of men after being falsely accused of burning a copy of the koran. there was no evidence. jennifer glass has this report

from kabul and we must warn thank you video you're about to see is disturbing. >>reporter: the last half hour of farkhunda's life must have been terrifying. an angry crowd calling for her blood. and that's what they got. hundreds cheered her killing. many filming it on their mobile phones where we got this footage. even in death they could not let her rest burning her remains in a nearby river bank. she was accused of burning the koran. but farkhunda was innocent and the backlash was immediate. at her funeral, women activists carried her coffin breaking with afghan tradition. and thousands demonstrated not just in kabul but in germany, london and new york. all demanding justice. that's what her family wants too. her mother says she made sure

all eight of her daughters including farkhunda were educated so they could contribute to society. >> the government should be held accountable for every drop of farkhunda's blood. she's not just my daughter, she's the daughter of the nation. >>reporter: her brother says the police on the scene should have saved her. instead the police chief initially told the media that farkhunda had mental problems and encouraged her parents to lie. >> he told us to say the same thing, that if we didn't angry people would burn the whole city. that we had to calm people down. >>reporter: farkhunda was killed in this busy part of kabul in broad daylight. her mother says the killing isn't a reflection of the whole nation but the false of just a few bad people. a few money meters away the spot where her body was burned as become a shrine and those praying here say those

responsible should be punish. >> it was a shameful act for our nation and our people and for those in power right now. >>reporter: the presidential commission initially found farkhunda innocent saying the killers were illiterate and the police failed to do their duty. how poor the security system to protect women in afghanistan. because when you talk to the police officers some of them will actually think mentally that it was her right to be killed. that's why they didn't act quickly. >>reporter: 27 people are in custody including 16 afghan policemen. ten or eleven are still at large and charges are expected to be filed soon.

afghan president ghani met with farkhunda's parents today but some critics say he waited too long. does the afghan government have the power, the desire and the capacity to do anything about farkhunda's killing? >> the afghan government certainly has the obligation to do something about farkhunda's killing and the incredible violence against women throughout the country. we need to see more training of police and more female police officers. we also need to see justice in police action as well as the action of people who instituted the silence and killed farkhunda. >> her killing has a lot of afghan women up in arms. how dangerous is it for them to do what they're there to do?

>> it's incredibly dangerous for women's rights defenders in afghanistan. on tuesday we're launching a report specifically about -- there have been car bombs, the killing of family members, targeted assassinations specifically at women defending women's rights who speak up about this. so the incredible courage it takes for these women to speak up not only about this incident but about levels of violence and discrimination is incredible. women in afghanistan have stood up to make sure that we're talking about this and to demand justice. >> and it's a problem in many other places around the world but hopes were high when the taliban was deposed after 9/11 but afghanistan is still ranked one of the worst countries in the world for women. >> after the fall of the taliban

in 2001 there were advances for him for education, voting. we saw a modest decline in violence against women but unfortunately in the last number of years we've seen an increase in violence against women and a backlash globally against women claiming their rights so as they access more of their rights they're more likely to become targets of violence. >> three quarters of afghan women despite being able to enroll in school they're still illiterate today and the majority of girls end up as child brides in afghanistan. do you expect to see progress in the near term? >>reporter: education of women and girls is a critical step forward for that and the forced marriage of girls is a huge human rights problem and a violation and there's multiple steps that the afghan government needs to take to ensure that not only do women and girls not experience violence like mob violence but of course the violence of forced marriage or

ignorance or lack of education so they can't access their rights. i think the afghan government has an opportunity with the new president to ensure their rights are being upheld and protected and to really prioritize the rights of women and girls. >> the new first lady is very accomplished with two masters. do you think her example will help? >> i think so. i think that it's important to have visible role models in women but there are a number of qualified women in afghanistan that need to be in positions not just as the first lady but need to be appointed in the administration as vice presidents in the supreme court and at all levels of government as fits their qualifications. so the more women we see in these roles, the more important it is for us to see these women and the more it means that women and girls can see those examples. but it also means women are a critical part of the decision-making process including not only questions of

family and education but in future peace talks and negotiations with the taliban or making decisions. >> it's good of you to join us. thank you they were promising to bring equal rights -- five female activists are behind bars facing charges for protests they were never even able to carry out and when we tried to speak with one of their families we were turned away by the chinese government. >>reporter: this is one of the five activists now detained. a high-profile advocate of gay and women's rights. she and other campaigners have helped raise awareness on issues ranging from domestic violence to more public toilets for women. they were planning a protest against sexual harassment when they were arrested almost a month ago. her lawyer says he's astonished

by developments. >> i was shocked. such a gentle way of expression could be cracked down like this and trigger so much response from the government. i'm puzzled. >>reporter: it's understood that two other activists are being held at the detention center northeast of beijing. it can accommodate 4,000 inmates. the other two women have been moved to a police hospital. one woman is being treated for hepatitis, the other has a heart condition. the women are affiliated to a nongovernmental organization whose offices were raided by chinese security agents last week. they took away files and computers before changing the door lock. police wouldn't respond to our request for comment. the women are accused of disturbing social order or in the words of the police picking quarrels and provoking troubles. it's a crime with no clear

definition but it allows police unlimited discretion to detain and arrest suspects for almost any action. >> detain on the charge of picking quarrels and provoking trouble when the event they were planning is two days away. so even by chinese legal standards, there's nothing to detain them on because the event they were planning hadn't even taken place yet. >>reporter: as international pressure mounts on china to free the activists, beijing has warned no one has the right to ask china to release relevant persons. if the women are charged and convicted they face up to three years in jail. the mother of one of the activists agreed to talk to us but when we arrived at her village outside beijing, police were guarding the only entrance and told us to leave. lawyers for al jazeera english, our sister network, have gone to court trying to

free two journalists being head by the nigerian government. they were embedded with the nigerian military when they were detained some ten days ago. they are reportedly being held for operating without accreditation. the court order was filed after they were denied access to their phone and contact with the outside world investigators have now found the second black box from the german wings flight. coming up what clues it may hold. y hold.

concerns was the verdict of the united international organization on thailand's aviation industry. already about 100 charter flights to japan alone have been canceled and some 30,000 tickets either refunded or modified. china and south korea have followed the lead and banned new flights. singapore is imposing strict inspections. experts say it's not unimaginable that the european union and u.s. authorities do the same. thailand's transport minister says that the aviation sector here has struggled for more than a decade to meet international safety requirements. now the government wants to use sweeping new powers to deal with the situation urgently. >> i need to use special measures to tackle many issues. that's why we need article 44. we will use it constructively. >>reporter: article 44 is a

paragraph in the interim constitution last year that gives the ruling council known as the national council for peace and order or ncpo power over all branches of government. that you are argument is that these extra powers are needed in certain circumstances. >> you need to strike a good balance between using executive power the right way and using power the wrong way. and in the end i think the combination of executive and democratic power used carefully would get us out of this transitional period. >>reporter: but the political opposition is concerned. they point out that this is an important time for different voices to be heard because the new constitutions seem to be debated and elections held. >> article 44 is also a symbol of -- to use this even once

means that you are expressing that you are in a system which is a dictatorship. >>reporter: martial law has been in place for ten months and they have come under international pressure to lift it. now it has and seemlessly replaced it with article 44. it's been nearly a year since a ferry sunk off the coast of seoul, south korea killing more than 300 people mostly high school students. today relatives of the victims shaved their heads in protest saying government officials are trying to buy them off instead of thoroughly investigating the incident. yesterday the government announced it would pay the victim's families $400,000 each in compensation 33 years have now passed since britain went to war with argentina over the falklands
