international support for their military intervention. foreigners trapped in yemen are desperate to leave. about 350 indian citizens left for gentleman abusivedjibouti in this ship. >> there is an invasion by the houthi rebels and ex-president al saleh groups are there trying to invade and to take hold of the provincial palace in order

just to show two things first of all, that aden is in their hands, that's what they wanted. and they want also to declare to everyone that -- that's what they wanted really. and they don't care about shelling and bombarding and using all kinds of artillery against civilians, against houses, and they're shelling everywhere. they don't care about anything. they are militias who don't have any conscience unfortunately. very much worried about what is going to happen in the coming few hours. if there is no kind of

intervention or support. >> a spokesman for the houthis explained their presence in the south of yemen. >> we've been in aden from the beginning but there were not enough of us to take control of the city from groups loyal to hadi and al quaeda. we were also in the provincial palace in the beginning. today, reinforcements have arrived. nine british nationals have been arrested for trying to enter syria illegally from the turkish side of the border. it's not clear why they were trying to cross the border but an estimated 600 britons have joined the conflict in syria and in syria, rebels have seized a crossing from jordon. the rebels were joined by the al quaeda-linked group al knews

of the 18,000 civilians who were there. now, remember amongst those are 3,500 children. and their lives are in danger. >>reporter: the palestinian refugee camp has been under siege since 2013 with tiny amounts of aid getting through. human rights groups say women are dying in child birth and children of starvation. isil has fought the free syrian army sections around the camp before but was pushed out into nearby districts. activists are concerned that though isil has left the camp this time around it fighters are bound to return in a bid to push into the center of the capital. >> al-nusra now, they are besieged -- and the other syrian opposition fighters like the free syria army and areas like east of here and the

the iraqi prime minister has confirmed that most of tikrit has been retaken from isil. fighters from the group have been driven out of the central city but at least three outer neighborhoods remain under their control. >>reporter: iraqi soldiers hoist their country's flag atop buildings in the city of tikrit the government is hailing this as a massive victory in the fight against the so-called

islamic state group. within hours of recapturing the city the prime minister headed there promising to restore normalcy as soon as possible. >> we will work to return displaced families. god willing, iraq will be liberated from isil and their crimes. >>reporter: the northern city of tikrit had been under isil control for several months now. it's seen as hugely strategic because it provides a gateway to mosul where it's believed the group's main leaders and operation centers are based. the fight against isil is not so straightforward. as with much of iraq's conflicts, sectarianism is life. tikrit is a sunni city yet the iraqi army used shia militia to enter it who in turn made their presence very clear raising flags with shia slogans on their vehicles and even on top of

government institutions. >> the pmf and the army are now inside tikrit and it will be liberated entirely soon. >>reporter: dead bodies said to be of isil fighters line the roads in the center of tikrit a sign of how bloody the battle was. capturing tikrit is a major boost for iraq's army who seemingly folded under the advances of isis a year ago. isil has found support in the north of iraq because of oppression felt by sunni residents there. there already have been reports that sunni homes have been destroyed almost immediately after the army recaptured the city. recapturing a city is one thing but winning back the trust of iraq's sunnis may be more difficult. in russia rescue workers

>>reporter: many people were convinced he could fix nigeria's problems. he was the former vice president, highly educated with a ph.d. in zoology. he promised to deal with boko haram when he was campaigning but critics say the problems only got worse. >> the area that did worst of all was the area of securing nigerians. it's a very sad thing. so many people died and it was as if the government didn't care. but at the end of his tenure corruption became the culture of nigeria. of course the oil sector became awash in corruption. >>reporter: thousands of people died under jonathan's watch and hundreds of thousands were displaced. weeks before facing re-election, the government says it reclaimed all the territories once controlled by the group.

>> president jonathan did not cause the boko haram crisis. it was an inherited crisis. there will also be security crises crises crises. these territories have been more or less taken by from boko haram haram. >>reporter: when he conceded defeat, he said he'll be remembered for setting the country on a path to true democracy. >> i promised the country free and freer elections. i've kept my word. for nigerians to participate in the democratic process is my legacy. >>reporter: he'll go down in history as the first sitting president in history to lose an election and hand over power but also to have presided over the worst peacetime crisis in the country's history.

boko haram. >>reporter: many of his old allies are now working with the opposition leader who won the seat as president. france's foreign minister says negotiations under iran's nuclear program are close to the finishing line but the final steps are the most difficult. iran and six world powers have extended the talks for a second time in switzerland after tuesday's deadline expired. simon wood reports. >>reporter: it's clear the talks which stretched from late tuesday and well into the early hours wednesday morning have made progress on a number of key issues. but it's not clear there has been enough progress for a full framework agreement. leaving the talks, the iranian foreign minister spoke of his optimism. >> we've been working since 7:30 this in the morning. we have accomplished quite a bit but people needed to get some

rest and start over early in the morning. i hope that we can finalize the work on wednesday and hopefully start the process of drafting tomorrow. >>reporter: the russian foreign minister was also up beat as he headed out of the hotel in the early hours. he and both the chinese and french foreign ministers are no longer directly participating in the negotiations. but there was a warning from the british foreign minister that there's still difficult work to do. >> i think we have a broad framework of understanding but some key issues still have to be worked through and some are quite detailed and technical. but we're on it now and we'll keep going at it. >>reporter: negotiations to conclude some kind of framework agreement have continued on wednesday and secretary of state john kerry met one on one with

his iranian counterpart with the sense that talks are entering their final crucial hours. it seems that on balance, the sides are going to fall short on the kind of agreement they really wanted to achieve here. the iranian deputy foreign minister speaking to his media has indicated the sides are now working towards the release of a press statement at the end of wednesday but he says there are also key difference on things like sanctions and research and development of key nuclear technologies critics say since china's president came to power in 2012 at least 500 human rights activists and disdents have been arrested and jailed and now there's growing concern about the fate of five female activists detained more than three weeks ago. they were arrested ahead of a protest being planned for international women's day. >>reporter: this is one of the five activists now detained. the 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 on like this and could trigger so much response from the government. i'm puzzled. this sends us a message. >>reporter: it's understood that three activists are being held northeast of beijing. the detention center can accommodate 4,000 inmates. the other two women have been moved to a police headquarters. one is being treated for hepatitis and 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 allows the police unlimited discretion to detain and arrest suspects for almost any action. >> detaining on the charge of picking quarrels and provoking trouble when the event they were planning was two days away. even by chinese legal standards, there's absolutely 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 that no one has the right to ask china to release relevant people. if the women are charged and

convicted, they face up to three years in jail. the mother of one of the activists had 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. marshal law has been lifted for the first time in ten months. here's more from bangkok. >>reporter: it's a vaguely worded paragraph in the constitution which came into place after the coupe of 2014. the prime minister has had article 44 replace marshal law which is a rather specific seven-page document in the thai

context. it allows the leader of the government sweeping powers in any situation that he judges it necessary to take over the powers of the judiciary, legislature, et cetera. there are criticisms already coming in from human rights groups that this marks as the human rights watch group puts it descent into dictatorship for thailand a new vaccine is being unveiled in india as a cheaper method to preventing death in young children. it's expected to be available next month and is the first to be produced in the developing world. >>reporter: it's children who live in poor areas like this one in new deli who are most at risk of infection. many of them preventible.

her 5-year-old daughter died a few months ago from severe diarrhea and says it's impossible to protect her family from threats like this. >> of course i'm angry because if the water was clean, if the outside was clean, why would my daughter die? why would my children fall ill? we don't have money to treat her in a fancy hospital. for poor people like us this is what happens. >>reporter: unsanitary conditions lead to more than 300,000 child deaths from diarrhea in india every year. one-third of those are caused by this the rhoda virus which causes severe diarrhea in infants and young children. most of india's poor don't have access to affordable vaccines. now this lab has the first vaccine for the virus made outside europe and the u.s. at about $18 vaccines on the market are too expensive for most families whose children are likely to be infected.

the new vaccine will cost about $3 making it more available for those in india and across the developing world. in clinical trials the new vaccine is shown to be about 58% effective, similar to other vaccines. but its makers say it's only part of the overall solution. >> it's just impossible to clean up everything overnight. but this part of the sanitation program if you combine it with this and combine it with the sanitation you'll get maybe 100%. >>reporter: those who work with the poor agree saying simple steps can make a big difference. >> like boiling water, like hand washing, breast feeding is also really important because mothers use dirty water with milk powder. so we can really make a big dent in reducing the number of children that die through these simple interventions. >>reporter: health workers are trying to deliver that message

on the ground hoping that along with the potential of a cheap vaccine, children in these areas won't become another statistics . bolivia is a multi-lynning wall country. now the government is trying to ensure schools reflect the country's diversity by teaching a wider variety of languages. >>reporter: it's a very basic conversation but until recently spanish and perhaps english or french were the only languages taught in plifbolivian schools when

more than half of the country speaks indigenous languages. recognizing its indigenous heritage was consolidated with the election nine years ago of the country's first indigenous president. bolivia is already a multilingual and multiethnic society but for centuries that diversity was suppressed. but not anymore. now it's coming back. even being celebrated. bolivia is also looking outwards. all schools teach another european language mainly english. the aim is to help nonspeakers recognize an understand at least some of what they're hearing every day. >> basically they should learn enough to go to the market to buy food since many there are from the country side and they

speak amongst themselves. all those who speak the language speak spanish but not all who speak spanish know their language. >>reporter: those languages previously consigned to the country side are coming here with massive migration in recent years to the city high above la paz. >> the migrant here in el alto needs to know his identity and identity is language. it's essential to country, everything he knows. if you don't speak your language, you don't know your culture and you lose your identity. >>reporter: in the past many people indigenous included the original language was a sign of backwardness. and the policy has faced obstacles obstacles. but he bes with dialogue, those obstacles can be overcome.
