closer. more revelations about the co-pilot of the crashed germanwings plane as it's revealed ahe was treated for suicidal tendencies. also. >> i'm daniel schwindler in bolivia, where we're seeing a very colorful renaissance of indigenous architecture. >> saudi led forces have expanded their campaign against houthi fighters in yemen. egyptian ships have shelled houthi fighters advancing on aden. it's the first time naval forces have been used. but one strike hit a camp housing internally displaced people. the camp is in the northern haja province. at least 40 people have been killed there doctors without borders put that number at 29. a saudi led coalition has been bombing houthi positions.

backed by forces loyal to ousted president ali abdullah saleh. southern city of aden attack was repelled. tribesmen around the town of bahar in the central province of shabwa. houthi weapons stores and air deferences were targeted, al jazeera's hashem ahelbarra filed this report. >> these are the victims of a camp dozens were killed or injured. highest death toll since the start of the military intervention in yemen. the houthis say the victims were civilians who were forced out of their villages in the past and sought ref umg in refuge in this camp

in yemen. say the houthis or the blame. >> we stress we do our best to prevent civilian casualties. we reply to a source of fire, we have no confirmation, this was a refusingrefugee camp. >> targeted houthi fighters, the aim is to prevent them from advancing to the sea port city of aden. ammunition depots, antiaircraft batteries were also hit as was this command center run by the houthis. houthi supporters took to the streets of the capital sanaa to denounce the air strikes. >> this aggression does not effect us. it only increases our determination and our strength because we are a strong people. >> reporter: the coalition says its military campaign will

continue until houthi fighters and soldiers loyal to deposed president ali abdullah saleh hand over their weapons and join talks for a political solution to yemen's crisis. hashem ahelbarra, al jazeera. >> denied that the attack led to camp deaths. >> they are always trying ohave what's called a human shield. houthis they are going to places where there is some population, or reservation houses. they are putting their resistance there. also some airplanes coming they are hitting the residential places or refugee camp or whatever. >> with me now to talk more about developments in yemen is

yemeni journalist anu bakar el shami. the grimmest development of the war so far dozens of people killed allegedly displaced people in a camp in northern yemen, both sides blaming each other. we heard the foreign minister there, saudi foreign minister. an aid tack, if it is the responsibility for the coalition who have the jets of course in the air what is that likely to do to the integrity of the saudi led coalition and the operation at a whole? >> i think it would be a propaganda victory for the houthis and the forces. i guess this shows the rest of the world that yemens, this is a foreign congregation against yemen that they are at risk. yes it will have the effect on

locals in yemen especially places like sanaa yet not as many civilian targets being hit they will be next, they will have the fear of getting struck by these strikes. >> it is the collateral damage that is common in any conflict. is it do you think a tactic of the houthis to store their weapons and arm amounts in civilian-pobtedpopulated areas? >> there have been numerous reports over the last few days of antiair craft stores in civilian areas. it is not beyond the realm of possibility. in the capital itself there are many, many bases army bases security installations in

residential areas. so any attack like this brings on the fear that attacks on military targets or potentially security targets could therefore then strike civilians and meet civilian deaths. >> couple other big developments in the day egyptian war ships firing on houthis marching towards aden in the south and pakistan the first nonarab nation to offer troops to the coalition. what does this tell us about the operations of the saudi led coalition at all is it succeeding or likely to succeed? what is next? there is word of ground troops. >> if there are ground troops in my own opinion that would lead to a quagmire. from experiences of the 1960s. these places are very dangerous for foreign forces to come into. it's very hard for them to come in. i think any incursion like that would lead to protracted

conflicts. >> we'll leave it there, thanks so much. u.s. secretary of state john kerry has told al jazeera that foreign ministers are working quote, very hard to reach a deal with iran on its nuclear future. last full day of talks before tuesday's deadline. foreign minister sergey lavrov will leave unless there's a possibility for agreement being reached. james bays is in lausanne. >> is it going well secretary kerry? >> we are working hard, working hard. >> reporter: u.s. secretary john kerry is spending most of his time here in lausanne trying to turn out an agreement.

nigerian capital with the latest on the vote count but first here's a report from haru mutasa. >> reporter: grace worries about the next few days. she works at a market in the commercial capital lagos. now that voting in nigeria's presidential and parliament elections is over she hopes for one thing: >> i want peace i don't want fight. i want to initially have peace and no fighting and to stay at our seller market. that's what i want. >> people in lagos appear to be getting on with their lives. the streets look busy but relatives 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. nigerians don't want election day violence they just want their lives to move on. saying they will only believe

official results. >> any one they want, rule this way. let the nation feel 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, mohamedu bohari, four years on it's deja vu for nigerians now it's also the continent's largest economy so people wait. they will find out soon who has one. haru mutasa, al jazeera lagos. >> yvonne ndege joins us. yvonne, early results trickling in, it's perhaps too early to get a clear idea what's going on. bring us up to speed.

>> jonah you're absolutely right. eight states including the set has been announced at the international conference center in abuja by the head of the nigerian electoral commission. we know the presidential candidate there muhammedu boharu is winning. there are still another 28 states for which the results are to come down here to the international conference center and there are a lot of statistics to get through and numbers for the electoral commission to make public the number of voters who are registered in these 36 states of nigeria have to be announced the number of accredited voters. each of the presidential candidates and exactly how many votes each of the 14 presidential candidates scored. also the number of spoiled and cancelled ballots, the number of

rejected votes have to be announced and once that process is through then the tabulation of which candidates got more than 25% in the 36 states have to be announced. and to win this race, the candidate has to get more than 25% of the vote, in at least two-thirds of nigeria's 36 states. now i asked the electoral commission boss earlier when he was here, how long is this process going to take? and he told me quite frankly be prepared to spend the night here. because the numbers from the biggest states in nigeria like lagos in the south like karno in the north which have populations anywhere from 15 to 20 million are supposed to arrive. nationally we know that at least 60 million people took part in this election. in over 150,000 polling stations across the country. so we have a long way to go before i think an official and definitive result is announced. >> complicated staff and a long
