welcome to the news hour. our top stories, heavy fighting in yemen's southern city of yemen as houthi fighters try to take control of it. >> plus. >> this is a moment for everyone throughout the country to be vigilant as we confront our enemies. >> kenya's president vows to

step up security after a deadly siege at a university where students are still being held hostage. isil fighters pushed back from a yahr yarmouk re -- refugee camp in syria. houthi rebels of taking control of yemen has reached its second week. on the ground as rebels continue to battle forces loyal to president hadi. there are conflicting reports from the city of aden about the houthi storming the home of the president. there were reports earlier that troops were seen getting off

ships in a port in yemen, yet, many officials say there are no ground troops in yemen. early on thursday al quaeda fighters stormed a prison in the east of yemen and freed hundreds including one of their leaders. and saudi arabia is reporting its first casualty. one of its soldiers was killed by gun fire from across the yemeni border war has let to a lockdown in the capital of syria and only a few businesses remain open. >>reporter: a food store that's open for business in what's become something of a rare sight in a city under bombardment. the war in yemen has not only forced people to flee their homes but as 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. hardly anyone comes to buy anything anymore. >>reporter: what makes things more difficult is that the shop is not far from the airport and a military air base. prime targets and saudi-led air strikes in yemen, almost 1 million people under the anal of 5 are malnourished and the world food program says most yemenis depend on polluted water for drinking. >> even though food and other products are available, the average yemeni can no longer afford to buy anything. add to that the fact that many families are now displaced making poverty and unemployment rise drastically. >>reporter: and ali finally has a customer but all he buys a cup

of water. >> if the situation stays like this i'm sure i'll be out of business within days. >>reporter: as the war rages on for the ordinary citizen, every day is a battle for survival >> joining us for more than the situation in yemen is mohammed khobati who was an adviseor for the last three yemeni prime ministers. >> aden is the main city in the south of yemen and was the third or second busiest port in the

world. it overlooks the aribabian sea and the aden gulf. so them taking over aden shows they've taken over the first capital. >> is there significance to them taking the presidential palace? >> i think it's just to boost morale. it's on the sidelines and far away on the tip of the peninsula of aden. so they have managed to cross over there. and i think if they could claim it they would claim they're controlling because they're up on the mountains mountains.

they are taking the mountains all around just to claim sort of a victory to boost morale because they are, you know facing iran now. >> we're expecting to hear from the saudi defense minister later today about this offensive which is now in its second week. i mean this is an air offensive for the time being. what do you think is going to come out of this speech by the defense minister? are they going to move to the next stage which a lot of people expect would be ground invasion of the coalition force? >> it should be ground but not a typical ground invasion. i think they need boots on the ground to help the yemenis who are fighting across the area. obviously the former dictator saleh, is obviously trying to mix cards. he appeared today to try to get al quaeda, and we know they're

backed by him, this second city in the south which is a sea port again, so that he could say that everything is just you know great. because he was all the time threatening to push yemen into anarchy and chaos. if they don't hunt this man, he's a big mischief maker and he'll continue to disrupt the whole situation there >> all right. thank you very much. joining us on the situation in yemen. in other news, al thatshabaab

most students were asleep. the gunmen shot dead security guards before firing at security guards. witnesses say there was panic and confusion amongst students. >> it was around 5:00 and guys started jumping up and down and running for their lives. it's unfortunate that where they're going is where these people are coming from. ed al shabaab says it's holding students hostage. >> residents around the school tell me that the place looks like a war zone. >>reporter: al shabaab has carried out numerous attacks

against kenya. in may last year two explosions hit the city of mombasa and in june they killed people in another town. they opened fire in a bar while people watched the world cup on television. there have been numerous other attacks in kenya's president says his country is fighting what he calls a war on terrorism. in february teachers took part in protests in the capital nigh row bee calling for soldiers andnairobi calling for soldiers and police. kenya's president says his country suffered unnecessarily because of a shortage of security staff. he's deployed extra military

personnel to end the hostage standoff. >>reporter: the university siege is the fourth major attack in northeastern kenya in the last year. there have been other smaller attacks. the population in this area have been discontent about it. a lot of people feel the government is not looking after them properly. meanwhile, the government says it's doing everything it can and putting more troops into the area and taking added security measures. following the deaths of the hostages in the university the president spoke to the nation. let's take a listen to what he said. >> on my own behalf and behalf of my government i extend condolences to the families of those who have perished in this attack. we continue to pray for the quick recovery of the injured and the safe rescue of those still being held hostage. i also assure the nation that my government has undertaken

appropriate deployment to the affected area and is fully aware of the situation. i also take this opportunity to urge kenyons to stay calm as we resolve this matter and to provide the authority that any information we may have in connection with any threats to our security. >>reporter: meanwhile, communities here are very taken by what's happened. lots of the students from the university come from the town itself. others come from towns throughout the area that's been affected by this conflict. these communities are looking for answers to why this happened why their young relatives and students weren't safe here when they came to study and try to make their lives better and ended up losing their lives in a conflict that they never wanted to be part of the kenyon government is offering a reward of $200,000

for information leading to the arrest of this man. they believe he's behind the attack on the university. mahmood is said to be a leader of al shabaab and on the run in kenya. he claimed responsibility for last september's assault on a bus in which 28 people died iran's foreign minister says significant progress has been made over nuclear talks in switzerland. marathon meetings are continuing two days past their deadline. what we expect today is a statement and the fact that we

have all reached common understanding on how to resolve the issues. but the agreement, a written agreement, is something that needs to be drafted by all participants and agreed upon in a multilateral process and that will take hopefully three months to finalize hopefully less. >>reporter: so a joint statement allowing a more detailed agreement to be written down by june 30th. at that point, there may even be a u.n. security council resolution to enshrine it in law. if there is an agreement, it will be presented by the iranian foreign minister and the european union's foreign policy chief. but exactly where and when this will happen is for now, anyone's guess. as before the sticking points seem to be iran's desire for

quick and meaningful sanctions relief and their insistence on research and development. >> iranians wants all six resolutions to be terminated. the p 5 plus 1 has other ideas about whether or not that's a good idea . and on research and development, iran would like to increase the amount over the duration of any deal signed. >>reporter: for president obama who has been briefed by his team a solid agreement is essential to keep a skeptical congress at bay and prevent new sanctions on iran. on thursday a deal seems within reach but it's not clear how comprehensive it will be. coming up on the news hour calls for change in afghanistan after the brutal mob killing of a woman plus

and in sports andy murray marches on at the miami masters. details late in the program. te in the program. iraqi government forces and allied troops have retaken the northern city of tikrit from the islamic state of iraq. the city was seized by isil last summer and the campaign to take it back has lasted more than a month. iraqi prime minister visited tikrit on wednesday and promised to help displaced people return home just 20 kilometers away from tikrit, some people are demanding they be allowed to go home. isil has left and the city has been destroyed. but shia militias fighting along side iraqi forced ruined their

homes deliberately. >>reporter: birds singing are the only sounds of life here. belongs are scattered amid the rubble of homes. stores are shuttered. this mosque destroyed. 120,000 people used to live in this city about 20 kilometers outside tikrit. >> now they're living in tents, portable containers and unfinished houses in several iraqi cities. >> we're financially and physically challenged. our morale is devastated. many families are living in hysterical ways. >>reporter: in march, iraqi security forces and shiite militias pushed isil out and then left to launch their offensive in tikrit leaving only the shia militias in this battered city of booby trapped and looted homes. sunni refugees say the shiite

militias not isil systemically destroyed their homes to keep them out of the town forever. >> are there hidden agendas about the town? we want officials to tell us if we can go home or not. we want answers. >>reporter: both the shia militias and the iraqi security forces we spoke 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 on them to help. >>reporter: when military operations began in tikrit, those still left in el dor fled to avoid more violence. it may now be safe enough for them to return but they say they still fear the militias controlling their city. in egypt, gunmen have killed at least 15 soldiers and injured

dozens of people after multiple attacks in the northern sinai peninsula. the region has seen an increase in violence since the overthrow of president mohammed morsi in 2013. turkish have arrested ten people with suspected links to a terrorist group. on tuesday a prosecutor was killed when police tried to rescue him from gunmen who had taken him hostage. and on wednesday, gunmen tried to storm police headquarters in istanbul an israeli soldier has been wounded in the occupied west bank. local media is reporting the stabbing happened at a checkpoint. here's the latest from jerusalem. >>reporter: according to them a palestinian along with five others tried to penetrate in

their words the separation wall and israeli group of soldiered happened on them during what was described as a routine patrol and that's when the altercation occurred. as we know an israeli soldier was wounded in this altercation and the palestinian man who allegedly attacked the soldier has been taken into custody as well as the five other men who were with him at least 17 people are dead and 36 others injured after an explosion at a protest in eastern afghanistan. the bombing took placeout outside the acting governor's home. a local member of the parliament was among those wounded. the taliban denies responsibility for the blast meanwhile, the murder of a woman by a mob in afghanistan has sparked calls for better training for police and better

treatment for women. jennifer glass has more. >>reporter: the last half hour of her life must have been terrifying surrounded by an angry crowd calling for her blood. and that's what they got. long live islam the men shout as they beat her with sticks and stones jumping on her body. hundreds cheered her killing. many filming it on their phones where we got this footage. even in rest they could not let her rest burning her remains in a nearby river bank. she was accused of burning the cokoran. thousands demonstrated at her funeral, 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 her daughters were educated so they could contribute to society. >> the government should be held accountable for every drop of her 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 she had mental problems and encouraged her parents to lie. >> he told us we should say the same thing, that if we didn't then angry people would burn the whole city that we had to calm people down. >>reporter: she was killed in this busy part of kabul in broad daylight. there's a new sign here now, martyr avenue. her mother says the killing isn't a reflection of the whole nation but the fault of just a few bad people. a few hundred meters away the spot where her body was burned has become a shrine and those

praying here say those responsible should be punished. >> it was a shameful act for our nation and people. it is a shame for those in power right now. >>reporter: the presidential commission appointed to investigate the killing officially found her innocent. it said the killers were illiterate and the police failed to do their duty. >> how poor the system to protect women in afghanistan. when you talk to 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. six or seven are at large. it is expected they will be charged soon >> a second black box from the crashed germanwings plane has been found. a cockpit voice recorder

suggested that the co-pilot deliberately downed the plane. german investigators have also uncovered evidence -- 150 people were killed in the crash. the plane was flying from barcelona to germany a russian trawler has sunk killing at least 50 people. more than 100 people were on the board the ship when it sank. search teams worked in freezing water to rescue survivors now for decades the german economy has been the largest in europe with an economic and industrial base built on stability and growth. dominick caine has been to visit one small company which says german values are the key to success. >>reporter: for 20 years, she has been turning out high-grade steel products. it has a staff of 57 workers and

plan and there was money given to west germany to restart and economy to strengthen the economy and that's what we need for europe and for greece too. >>reporter: one analyst told me it's wrong to think leaders in berlin can compel other governments to do what they want. >> not only germany but all the european institutions are in effect -- to introduce the basic structural reforms. so the german power in europe is conditional. it has its limits. and germany cannot do everything it would like to do. >>reporter: but thoughts like that do not pacify people in greece who say eu imposed austerity policies have killed jobs and livelihoods. many say germany should still

pay reparations from the war in the 1940s. modern german governments have rejected that saying they pay more into the eu budget by billions every year. still ahead on the news hour we'll be live in switzerland where we've heard there will be announcement shortly on the iran nuclear talks that have been going on for some time now. extended past the deadline. we'll have the latest with our diplomatic editor. also nigeria's newly-elected president turns to problems facing his country, including the economy. why the care takers of a third of the planet's woodlands aren't taking enough care.

welcome back. there are conflicting reports from the southern city of aden in yemen about whether or not rebels have stormed the presidential palace there. the coalition campaign against rebels began last week kenya's government says two al shabaab gunmen have been shot dead in a hostage standoff. and iran and six world powers could be close to reaching an agreement over a nuclear deal. iran's foreign minister said a draft statement still needs to be written let's get the latest on those talks from switzerland. james, i understand that some kind of announcement is expected very soon. what are you hearing? >>reporter: yes, we've been told to prepare for announcement.

journalists have been sent e-mails telling us that there will be a press event taking place here about ten-minute's drive from here from a technical college. we don't know exactly what they're going to announce though. we don't know if it will a joint statement, an understanding, or what the white house and state department were originally promised a framework agreement with concrete details that the administration can take to capitol hill to persuade senators there's no need for further sanctions. what is certain at this stage is there's going to be some sort of press announcement taking place in a facility on the edge of town. we have no exact timing for that. i can tell you that many of the journalists who have been spending with us here days camped out in the hotel behind

me are now being put on press buses and those buses are taking them to that facility. i'll warn you that past experience, almost certainly when they get the other end are going to have to go through security screening and wait for some considerable time. i suspect this is not imminent. my guess is it's a couple of hours away. >> james, thank you very much. of course we'll bring you that announcement as soon as it happens now, the u.n. palestinian refugee relief agency is demanding an immediate end to the fighting in the yarmouk state in syria. antigovernment fighters have been defending yarmouk which is home to thousands of people. >>reporter: smoke rises from what is said to be yarmouk refugee camp in southern

damascus. those nearby listen anxiously to the sound of fun fire. isil stormed the camp fighting with antigovernment palestinian militias. it was the last people the desperate people of yarmouk needed. >> since early afternoon, there were fierce clashes in the vicinity 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 around the camp before but was pushed out into nearby districts. activists are concerned that though isil has left the camp this time around its fighters are bound to return

in a bid to push into the center of damascus. >> across the country, the syrian government is continuing its aerial bombardment. this was the scene in the newly rebel held city of idlid. activists say the regime is still using chlorine gas. a claim which syria denies.

i haddlib -- can you tell us who's in control at the yarmouk refugee camp? >> it's obviously a very worrying situation. it's very clear that the situation is deteriorating and the fighting that is taking place is affecting the population that has already been deeply marked by years of siege, of activities by armed groups inside the camp. and i was this month inyarmouk myself a couple of weeks ago and it was evident for everybody to see there that the population is at a breaking point. that people lining up for distribution and receiving food aid and medical assistance from us have gone through sort of a

depth of trauma and experiences of anxiety and hardship that are very difficult to properly convey. so of course when we heard about the current fighting and the development on the ground our thoughts were immediately, of course, with the population knowing that further displacement would, of course affect them in the most dramatic ways possible. exactly what is happening on the ground is very fluid and changing constantly so our teams were trying to get into yarmouk today had to turn back because of the intensity of what was going on. but we'll remain closely and carefully engaged there on the ground. >> many people have of course fled yarmouk in the last few years but many remain inside. what sort of life do they face daily and is aid able to reach these people trapped inside the camp? >> it's a life of immense dispair and suffering. you know the -- despair and suffering. the palestinian refugee who is

have been there for decades were people who were proud, educated self-sufficient, in charge of their lives, running businesses. and when i saw them lining up to receive food assistance and medical support during my visit, it really hurt in ways that i find difficult to describe. and their intake of food and overall assistance is of course far below what they would require normally. we were able last year to provide assistance on 131 out of 365 days. that is clearly insufficient. there's a clear link between the presence of armed groups inside the camp at the levels of suffering people are exposed to.

the conflict environments are always very challenging in terms of access and it's clear there's a link between the presence of armed groups inside the camp and the possibility for civilians there to access distribution points. it is clear also that the military engagements between government and opposition groups has at times prevented aid from getting in. so we are constantly in the search for proper access points or distribution points. it is our fundamental outlook not to give up in the face of these constraints.

are also among the worst climate change offenders. here's more on that story. >>reporter: this new satellite map generated from over 400,000 images is the most detailed researchers have ever had. those green dots are the places

where forests have been wiped out. you can see canada and russia really lighting up. between 2011 and 2013 those two countries accounted for most tree loss the world over. canada and russia lost a combined average of 6.8 million hectors of forest each year. that's an area the size of ireland. globally in 2013, forest cover equivalent to the size of cambodia was lost. that's more than 18 million hectors. global forest watch says the lost forests contained vast stocks so losing them is a big deal when it comes to green house gas emissions. >> joining us is the head of the forest program at the world resources institute in

washington. he's joining us from washington. tell us about the areas around the world where we're seeing such huge losses. what other factors are contributing to the losses? >> well the new information that we published today on globalforestwatch.org is very sobering showing that we're continuing to lose very large amounts of forests each year. the number is growing each year over the last decade. the tropics are seeing the highest rates of forest loss but as you said earlier in the report, we've seen this extraordinary surge in tree cover loss in russia and canada. a lot of that is linked with fires but also due to infrastructure development, the presence of the oil and gas industry logging and other industry moving into those northern forests. there is though some striking good news and numbers that really surprised us here as we

compiled the analysis. we've seen indonesia which was seeing the highest rate of forest lost in the tropics -- this may be due to a combination of factors related to the economy in asia as well as sustained efforts by the government of indonesia and partners like norway to address some of those issue >> the example of indonesia is certainly very interesting. what do you think governments like those in canada and the u.s. can do what measures do you think could help reduce these losses? >> well the country that comes out top of the list in terms of the highest rate of loss of tree cover is russia. and russia's forests are, i'm sorry to say, a bit of a wild west. so you've got somewhat uncontrolled expansion of infrastructure and people moving into those areas. law enforcement is quite weak. across canada and alaska and parts of the united states also

we continue to see quite high rates of tree cover loss. and as concern about climate change grows, really these countries need to redouble their efforts to address some of these issues. better monitoring better planning for the use of land better fire control efforts, addressing some of the illegal activities perhaps in russia would all help to address this. >> okay. thank you very much nudgeal, for that. california's governor has ordered a 25% cut in water use statewide. it's the first such order in the state's history. one reason one of their rivers is dying. industrial agriculture is blamed for causing the crisis. jennifer london reports. >>reporter: on a late afternoon day, this family is fishing for dinner near fresno california. chances are they won't catch anything.

the state's second largest and longest river is dying. topping american rivers list of the nation's most endangered rivers. >> it's really low. >>reporter: to find out why, i met with conservation expert john caine for a kayak trip on the river >> the most important reason why the river is in such bad shape today is it simply doesn't get enough water to be a healthy river. >>reporter: why is that? >> it doesn't get enough water to be a healthy river because so much water is diverted for agriculture. >>reporter: california's central valley is home to the nation's bread basket. crops that go here help feed the world with farms large and small making up 7 million acres of irrigated farmland. over the course of its 366-mile run, the river and its tributaries are dammed -- lemon orchard. >> are you the reason why it's the most endangered river in the

country? >> if you want to go back to when it was decided that the water was going to be diverted to go south to benefit a tremendous amount more people and grow crops that grow all over the world, you could say that was -- that killed the river. >>reporter: every day people drive right over the river. but what you can't see from the bridge is that there's no water here and there has not been for years. as you come down the slope and look this way, this was once the mighty river. at one time there was enough water here to carry steam boats 80 miles up river all the way to fresno. today all you'll find here is plenty of sand a couple of shells, and some footprints. and the parts of the river that have water are so low the once legendary migration of 500,000 salmon -- have had mixed results. >> so he's not a very big guy.

>>reporter: those living and working here worry about a future tied to the troubled river. >> i get to work and make a living off this river and it would be very detrimental to me. >>reporter: the state water board is in charge of water rights in the state of california. how has it been allowed to get to this point? >> everybody wants these things to happen of course quickly. in the end, there will be many people who will not like the specific answer but what we're going to do in this process is make sure we're relying upon the best science for the protection of fish and wild life and balance it again with the uses for agriculture. >>reporter: conservationists like john caine say increasing the river's flow even a small

amount can balance those needs. >> the river can be saved. the plan only calls for 25% of the river's natural flow to stay in the river. >>reporter: still, even that might be a hard sell during the state's historic drought which has only made a bad situation worse for both the farms and the fish so many people rely on. jennifer london al jazeera. all right. some breaking news out of kenya now where there are apparently developments in the northeast where al shabaab had taken hostage several students in the university. at least 15 people are reported killed. the siege began at dawn earlier today and we're getting news now that the situation might be over. let's bring in malcomb webb who joined us on the phone from kenya. what can you tell us? >>reporter: a short while ago there was a very heavy fire

fight and we could hear heavy weapons being fired and that's now all stopped. it's calm. we've spoken to two different people who were inside the university campus and they say it's over and most of the remaining hostages inside have been killed. he doesn't have any exact numbers and these aren't officially confirmed yet but the eyewitness we spoke to there, one young student, 22 years old, she says she's been stepping over more bodies than she can count to get out of the place that she was hiding. someone else said he saw over 100 bodies in there. there are a lot of ambulances rushing down the road presumably taking the injured hostages and soldiers to the military medical facility here. >> this is quite extraordinary. so eyewitnesses telling you that most of the hostages who are remaining inside the university have been killed. we had earlier, of course seen a lot of people escape. do we know malcomb, how many

were still left inside? how many of the students were still being held hostage by the armed men? >>reporter: we don't know. but this morning we spoke to a hostage who was inside and he estimated that there was possibly more than 300 in there and since then we've seen several escape. we've seen a few dozen come out on buses and they're being bus bussed away from the university to the military facility. the eyewitnesses in there now saying there are dozens of bodies and it has not ended well at all. >> well it looks like it anyway. we'll get confirmation on this obviously in the next few hours. no word from authorities but eyewitnesses telling malcomb webb that the remaining hostages inside the university have been killed. we're not sure how they died whether it was a gunman that killed him or whether it was during the fire fight with the

security forces that they died. but, of course as soon as we have more information we'll bring that to you. malcomb, this is the siege that had been going on since dawn today for many many hours. what was the security presence like there? the army i understand was involved? >>reporter: they were involved. initially when the attackers came at dawn we've been told just two armed guards were both killed by the attackers. a lot of soldiers and military vehicles have been going down the road. we've heard from reliable sources that in previous months the government was specifically warned about the security risk to the university here and also to training colleges. the whole of northeastern kenya is unstable and at risk of attack but some people thought that these institutions were particularly vulnerable because they have a large number of people here who are not from this area. they're kenyons who are not

ethnic ethnically somali. smeiomali kenyonan . >> dramatic developments once again out of kenya where malcomb webb has been speaking to witnesses who say that the remaining hostages inside the university have been killed. this happened during -- we don't know whether it was during a fire fight with the kenyan security forces who were inside the university. al shabaab gunmen had taken hostage several students inside the campus located northeast of kenya. many managed to escape but many more remained inside.

we'll bring you more information on this breaking news story out of kenya if and when we have it. right now we're going to take a short break. short break.

i'm thinking that -- it wasn't really their fault because the decision was -- at a time where really the fear was real because at the time the decision was being made don't forget that up to 300 to 400

people a day were dying because of the disease. there were lots of flights being canceled from west africa and considering that the african league of nations was going to have a lot of west african countries i'm sure -- making that decision. >> the fine of $1 million to just 50,000 is a big reduction. does this embarrass -- >> well it's a huge embarrassment. because, you see, you've seen them reduce the sentence given for one other incident. they have also for some weird

reason -- they vice president given to eastboundingorial tennis now. a third seat has booked his place in the semifinals of the miami masters. he got off to a shaky start losing the first set 3-6. he did fight back in the second to take it 6-4. murray cruised through after that and sealed the win. he'll now face thomas berlich in the last four serena williams won her 700th career match to reach the semifinals in miami.
