>> and discovery that the co-pilot of the jet crashed into the alps had been treated for suicidal tendencies. saudi led coalition forces are continuing air two strikes on sanaa. this was the scene as positions were bombed. hitting a area for glaised displaced people. hashem ahelbarra reports. >> these are the victims of a suze of saudi led air strike. dozens were killed or injured. it is the highest death toll since the military intervention in yemen. the houthis say the victims were civilians who were forced out of

their villages in the fast and sought refuge on this camp on the border with saudi arabia. saudi arabiaian officers say houthis are to blame. >> translator: moving to areas where you have civilians we stress we to our best to prevent civilian carnlts. we reply to a source of fire, we have no confirmation this was a refugee camp. >> reporter: the saudi led air strikes targeted houthi provisions in southern areas. their aim to prevent them from advancing towards the seaport area of aden. ammunition batteries and antiaircraft areas were also hit. capital of sanaa to denounce the air strikes. >> this congregation aggression does

not affect us, we are a strong people. >> reporter: the coalition says its military campaign will continue until houthi soldiers loyal to deposed president ali abdullah saleh lay down their weapons and join talks to a solution to the crisis. hashem ahelbarra, al jazeera yemen. back to the news of the displaced person's camp. we don't know it's clear to say who definitively launched this attack. an aerial attack, if that is the case, what sort of effect is that likely to have on the coalition on its progress on its cohesion amongst its members? >> well, i mean in terms of cohesion in terms of the

coalition itself i don't think it will put a stop to the strikes and i think they'll continue and try and shift the blame. >> collateral damage that -- >> these things happen if war. let's look at the bigger picture but the houthis and saleh they are already starting to use this and the attacks on sanaa of foreign aggression on the country. it is a pr coup. >> the southern port of aden currently under naval blockade, is it working, is the crucial question what happens next with people talking about the possibility of ground troops? >> i think the attacks are continuing, and the attacks will continue ton houthis.

i don't think though, i think it will be -- continues on the houthis. to stop them, pull out of the cities which a lot of yemenis are calling for to put a stop to this, what accommodation next a potential ground war, if the saudis do invade, it will prove to be very difficult for them. the only other option is some sort of militia or troops on the ground from the yemeni side and that doesn't seem to exist at the moment. >> of course even if the houthis did pull back, even if the houthis somehow were defeated. president abd rabbu mansour hadi in sharm el sheikh presumably, he didn't come back from the arab league conference, there would be no certainty he would be able to come back and rule. >> exactly, very difficult. he's always never particularly had a power base in yemen. he has always relied on the

international community for years, which is one of the reasons the yemeni community finds itself in the situation it's now in. who back him to the hilt, i don't think that's going to happen. >> okay, anu bakar al shemai, thank you very much for joining us. now early election results from nigeria's presidential poll suggests that opposition challengeers muhammadu buhari has a slight lead. election forecast to be the closest since the end of military rule in 1999. let's get the latest from yvonne ndege, yvonne you are watching the count. what is the latest? are we any closer to anything definitive? >> well, we are a little bit closer jonah. as i speak the chairman, the boss of the independent electoral commission is reading

out the results in this election and so far we know that the main opposition presidential candidate muhammadu buhari is in the lead, we know of the 36 states in nigeria he is currently leading in ten of those states, closely followed by eight states gone to president goodluck jonathan. it is still early stages because we are awaiting results from 18 states including are lagos which has 20 million people. that could be the deciding state. in addition, there are a lot of the information each has to read the number of people registered to vote, the number that were accredited to cast number of objected ballot papers and so on, so forth. on top of that once there's a clear winner in terms of the overall percentage, the winner

of the presidential race also has to get more than 25% of the votes in two-thirds of nigeria's 36 states. so we've still got some way to go. but if everything that we're seeing at the moment is right it is look going for the opposition. my calculation and it's a rough calculation is that at the moment, muhammadu buhari is leading with about 2.2 million votes ahead of the incumbent goodluck jonathan. >> yvonne bring us back to the basics of this election. the government oil prices, battling boko haram in the north is this a country hungry for change, do you think? >> reporter: people are divided about the whole issue of change. yes, there are many issues like the ones you've pointed out affecting the country. insecurity in the northeast but the biggest issue as you mention ed for nigerians is corruption. there are huge problems with

electricity supply. people are tired of excuses that's what they've told us as we've been covering the election and all aspects of issues that affect nigerians with the current government. the ruling party led by goodluck jonathan has been in charge of this country for 16 long years since the end of military rule and the word change has been floated almost everywhere you go. does that represent a real change? some would say no in many ways because a lot of the most senior officials within the opposition were once part of the ruling party. they were all members of the people's democratic party. they fell out with president jonathan and joined the opposition so some people are saying well, is this really going to be a change if muhammadu buhari wins? or willing the same problems affect and bedevil nigerians? so it's too early to say really where this situation is going to

head and whenever whoever wins this election will be able to achieve democracy given fact that all the candidates in this race and the two key candidates do have a lot of common politically speaking. >> fascinating stuff. yvonne ndege in abuja thanks. it's been nearly a week since the nigerian military are detained two al jazeera journalists. being held in maiduguri. al jazeera is demanding their release. linda thomas are is assistantgreenfield isassistant searkt.

hammond took a walk presumably discussing the remaining sticking points. >> in negotiations of such complexity and such high stakes it is not unnatural for brinksmanship to go on until the last minute until the 11th hour because each party is hoping the other will budge at the last minute. but i think the negotiators understand very clearly they are running out of time and this process is no longer sustainable. >> talks are continuing on the main areas the future of iran's research and development and the lifting of international sanctions but the time behind that deadline is fast running out. james bays, al jazeera lausanne. >> still ahead acknowledge rally for their rite to try unapproved drugs. >> and old hands generating new energy in the philippines the grandmothers bringing solar

>> people in lagos appear to be getting on with mayor lives. the streets look busy but residents tell us it's quieter than usual. the next few days are crucial. people don't know what is going to happen after final results are announced. many nigerians say they don't want to see election violence. they just want their country to move on. there is anticipation in many parts of nigeria. for most people remain calm saying they will only believe official results released from the election commission. >> rule well and let the nation be good about that. >> reporter: many know the threat of postelection violence is very real. more than 1,000 people died when the main opposition leader, muhammadu buhari led to incumbent leader goodluck jonathan back in 2011. four years on it's deja vu for nigerians. now it's also the continent's

parent company lufthansa has always stressed that mr. lubitz went through assessment, physical and mental assessment tests passed them and they considered him to be 100% able to take controls of the plane. of course we know he took the controls of the plane locked out his captain and plunged that plane in its fatal drop into the alps. francois hollande will be meeting angela merkel chancellor of germany in berlin obviously to talk about this issue and many others. francois hollande was the first leader to talk about these fatalities. and we know also there will be a memorial to be held in germany in clone germany the base for germanwings on april the 17th. the chancellor angela merkel and the minister joaquim gauk will

leave the premises and apparently the nsa police that guard that particular entrance, apparently, opened fire. the fbi is now the lead investigating agency and is trying to figure out whether or not criminal charges should be filed against the surviving person in this incident. >> the u.s. government is under pressure to speed up the way new drugs are approved so that terminally ill patients could take advantage of them earlier. kimberly halkett reports now. >> ten months ago jay smith was at the height of his career as an executive with a major company, and. >> a year later we're in the

would dramatically alter the way medicines are regulated in the united states allowing for possibly lifesaving developmental drugs to be fast-tracked for the patients who need it. ten states have already gathered terminally ill patients access to drugs without approval. laws are already in place in other countries. >> in europe, drugs tend to get approved earlier and in this country, it would save so many lives, it's doable. >> reporter: the u.s. government last year allowed u.s. ebola patients to receive life saying medicines. the smith say they simply want the same opportunity. >> that is what we're trying to for, if i have to wait i won't be arnld. around. >> reporter: they say they're
