>> is in nigeria the opposition challenger muhammadu buhari has been declared the winner of the presidential election. >> hello there you're watching al jazeera live from london. also coming up in the next 30 minutes. talks of iran's nuclear program will continue past the deadline of midnight. but officials say they must conclude by dawn. the saudi military continues it's offensive against the houthies in yemen but civilian

casualties are mounting. and a prosecutor and two gunmen are dead. >> nigeria has a new president. opposition candidate muhammadu buhari has been the winner. the former military ruler defeated incumbent president goodluck jonathan. this marks the first time in nigerian history that a president has been democratically voted out of power. well yvonne ndege there are a lot of challenges facing buhari. when he was speaking to a lot of people celebrating today, it's corruption, it's poverty and security and the fight against the boko haram.

what does the election mean for nigeria's future? how will he tackle all of these problems? >> well, barbara he has huge challenge toss overcome. the security that we've seen in this country. corruption has been an issue. billions of dollars have been lost over the last few years by the government because of corrupt practices that have been allowed to continue. there is also the issue of unemployment unemployment stands around 25% of the population. there is also a massive power crisis, a huge lack of electricity in nigeria which makes the cost of doing even the basic things so incredibly expensive. now a long time ago we managed to get inside the offices of president buhari is in the building behind me. we saw him at his desk, and we asked him what he's planning to

do next. he told us that he's preparing his victory speech once the final results are officially announced by the electoral chairman, and then the hard work of trying to fix this country begins. there have been so many challenges over the last 16 years since this country was ruled by the ruling party the people's democratic party. that's the party that lost the election president goodluck jonathan. and there is a lot that needs to be repaired. we spoke to people who are incredibly excited about this new change, and obviously president elect buhari will have to talk about the changes that people want to see. >> one of the remarkable things about this result is that it has been a democratic handover of power. what reaction was there to the result of the victory of buhari and how the election went. what reaction has there been to it? >> barbara, that's right.

the political significance of this event cannot be understated kins the end of military rule 16 years ago the country has been ruled by one party. many people doubted whether you could have a peaceful exchange of power. many said that it could not happen. many said that there would be tension and many said that there would be violence. many talked about civil war breaking out if this was not seen peacefully, if this election was not free, fair, and transparent. the reaction we're getting are people excited telling the president-elect what they want, how they want things to change. we've been around to various locations in abuja many people are out on the street incredibly happy and excited. here are some of the people that we spoke to just outside of president-elect buhari's house.

>> corruption. we have a problem of corruption. too much corruption. no security. we need to take care of nigeria. >> now there is still quite a process to go even though buhari has been elected by nigerians today president goodluck jonathan, who has conceded defeat, and called and congratulateed buhari will remain in power until the constitutional date of power which is the end of may. at the end of may president election buhari will be sworn in as the president of the republic of nigeria.

>> yvonne ndege from nay jeer i can't, thank younigeria. two al jazeera journalists have been detained in their hotel since tuesday. al jazeera is demanding their immediate release. >> talks on the future of iran's nuclear program will continue past the deadline of tuesday. the u.s. said that the negotiation has progressed that it merits staying until wednesday. simon mcgregor wood is in lausanne where the talks are taking place. it was an artificial deadline,

this midnight deadline, but i guess they have to stop at some point. have they created a new deadline? do we know what is going to happen over the next few hours? >> well, i don't think we do, but it's five minutes past the original deadline. it's suddenly become more flexible than it was with statements from the state department saying that we're not there yet. there are significant differences but we've made enough progress to push through the deadline. now we're into the early hours of april 1st, and we' hearing the french foreign minister is saying things like they're going to leave at 5:00 in the morning. 9the german foreign minister may hereof at 6:00, and john kerry

may also leave. it's not clear if that is brinksmanship for negotiating tactics, but we're in a critical period of this talks. the only real conversation that we've had with any of the participants today came from an iranian deputy foreign minister who broke cover early this hotel, and he was quickly surrounded by a gaggle of journalists. this is what he had to say about the progress of the talks so far. >> we'll have a deal when all issues are resolveed. there are unresolved issues at this moment that have not been resolved. we're concentrating on finding the best solutions which are mutually agreed by everyone. these efforts would be continued until we have those solutions. so we do not have any deadline,

6:00, 7:00 9:00. for us the whole day can end in the next morning so we're sparing no effort to find the best solutions. >> you we really don't know what the sticking points are but there have been a difference of opinions like the speed that the international sanctions will be lifted. and the extent that the iranians could do research and development and technology beyond that ten-year period where it's widely believed that it will be frozen and not allowed to do. we may not be getting a full

deal. it's very important that president obama gets some kind of deal very soon to present to the congress. many who do not like the deal at all are threatening to impose further sanctions on in april and if this happens many believe that this whole process will unravel all together. many issues for the hours ahead. >> simon mcgregor wood, thank you. saudi-led airstrikes targeting houthi rebels have continued in yemen. they have intensified their attacks north of the city of aden an area that they believe that houthi fighters want to

capture. we'll have more on the situation in yemen but first hashem ahlbarra. >> airstrikes in southern yemen. they say that the houthies and those loyal to deposed president ali abdullah saleh are advancing to try to capture 9 the sea port of aid. they are the ones who provide intelligence on houthi fighters seen here trying to set up a checkpoint on the outskirts of aden. moments later the checkpoint is hit. armed vehicles tanks, missiles launchers are also struck. >> there is a houthi presence inside and around the city of aden. we have intensified our attacks north of aden.

the houthi are desperate to get into the cities so they can take over. >> saudi arabia has said its military campaign will take some time accusing iran of helping the houthis to destabilize the region. >> iran has trained houthies. if they're currently present in yemen they will receive the same fate as the houthies. let me stress we will not allow anyone to provide assistance to the houthis in the air or in the city. >> president hadi is rallying international support in its pain. >> for the time being airstrikes continue across yemen showing no signs of slowing down.

there are no indications though, that the saudis will send troops into yemen in the near future. al jazeera. >> al jazeera has been told that a yacht belonging to yemen's ousted president ali abdullah saleh has been smuggled out of the country. sources say that the yacht that you can see here was loaded on to this cargo ship, which was then allowed a permit to leave shower. this is believed to be the second yacht owned by saleh to be smuggled out of the country. his whereabouts remain unknown. still to come on the program, a turkish prosecutor dies after the operation to rescue him from armed men. details coming up on al jazeera.

>> al jazeera america, weekday mornings. catch up on what happened overnight with a full morning brief. get a first hand look with in-depth reports and investigations. start weekday mornings with al jazeera america. open your eyes to a world in motion. >> now a reminder of the top stories here on al jazeera. there have been celebrations across nigeria after the country's main opposition candidate was declared the official river of the presidential election. talks on the future of iran's nuclear program will continue past the deadline of midnight tuesday. the u.s. said that the negotiations had made enough progress over the past few days to merit staying until wednesday. and saudi-led airstrikes targeting houthi rebels in yemen, the coalition has

intensified its attacks north of the city of aden. an area which it believes houthi fighters want to capture. let's go to our top story that's nigeria's elections. i find iting were that buhari did topple a democratically elected president. what makes him a suitable leader now? >> when he overthrow the government in 1984, it was i was a young student at the time. what he did in the few years when he was president was tackle some of the biggest challenges, corruption, and provided an element of leadership in nigeria, and it would appear

that he was overthrown by his military. the interesting thing is that leading to this election, some of the establishment evening military, did not want to see him lead because they know that he will tackle the corruption. >> so you mentioned corruption, and how it sort of already has been a track record. but security a mass issue, the fight against boko haram. how will he do in that challenge. >> he'll probably do better than jonathan. when boko haram was there national security is something if you want to provide leadership, good luck jonathan would have called on nigerians to fight boko haram. did he not.

buhari spoke their language and acted as parent of the nigerian nation. being from military, particularly someone who is a doer brings slightly more optimism. i know more people are cautiously interested in him. but as i said before, he is the better of the two devils. >> this is a democratic transition of power. >> extremely important. >> and hopefully there won't be any violence. we have not seen hint of it yet. >> if there is any credit to be given to goodluck jonathan, the outgoing president, he did it timely. he conceded defeat and asked his supporters to rally behind--that's important for that country. they badly need it. to fight boko haram they need to come together as a nation.

they have support on the continent, and all of us are watching them. >> certainly a key player. we'll have it leave it there. thank you so much. >> thank you. >> a turkish prosecute who are was taken hostage in an armed group has died after being rushed to hospital. he was investigating the death of a teenager during protests two years ago. the gunmen had demanded that police officers involved admit their guilt live on tv or the prosecutor would be killed. bernard smith has more details from istanbul. >> istanbul's main criminal court, police special forces storm the room where a prosecutor was being held at gunpoint by two armed men. the gunmen were killed in the shootout. the prosecutor critically injured was rushed to hospital. the doctors were unable to save

him. >> where isthe attackers were also focusing on the prosecutor. >> the prosecutor had been investigating the death of a 14-year-old teenager who had been hit by a tear gas canister during the protest during the summer of 2013. the parents and others say that the investigation into his death has been too slow. the hostage takers wanted the prosecutor to reveal the names of the police officers suspected of firing the tear gas. >> we learned that this action was in connection with the investigation belkin elvi is our son, our brother. >> the investigation of how this

unfolded is how the armed gunmen were able to get their weapons into the courthouse. everybody going into the court is searched except for lawyers. >> belki n elvin's parents asked the gunmen not to use the guns. blood cannot return blood. >> obama will allow the delivery of f-16 planes as well as other military aid which had been suspended following the 2013 coup in the country. obama said he would continue to ask the u.s. congress for $1.3 billion in military aid for egypt each year. well, rosalind jordan joins us live from washington, d.c. roslind, why has the president changed this by now? >> well, that's very precise about what the bomb administration has decided to do. they're giving this equipment

the chance to upgrade egypt's tanks, the f.-16 fighter jets. they're giving this equipment for what they say are national security reasons. and certainly they're looking at the ongoing instability in the sinai peninsula as well as the intelligently going stability in neighboring libya. this has nothing to do with whether the u.s. believes egypt is doing enough to improve it's human rights record, and improve its treatment of journalists. whether it's doing enough to improve its treatment of political opponents. the obama administration is basically saying that it does not believe that egypt has made improvements in these areas and, in fact, it's going to restrict how egypt can use the aid that the u.s. is going to be requesting for it in future years basically as a way of saying you need to get your house in order. >> roslind jordan with the latest from washington, d.c.

thank you. >> the round up now to some of the other main headlines. the head of libya's tripoli-based government has been sacked by his own ministers. he was dismissed after being accused of misleading parliament about finances. they say he was sacked following complaints by the central bank and other ministers. but his dismissal should not impact u.s.-sponsored peace talks. german airline lufthansa said that it knew six years ago that the co-pilot that literally crashed a passenger plane into a month killing 150 people suffered from a serious depressive episode. search operations continue in the site of the crash of the german germanwings flight. they say that the andreas lubitz had passed all medical tests and was cleared to fly.

peru's government has declared a state of emergency for three regions effected by heavy rains and landslides and flood. 15 tons of aid has been dispatched to the effected area. peru weather forecasters say they forecast the chance of el niño conditions starting in may, which can trigger flooding in some parts of the world. argentina's powerful transportation union has kick odd a off a 24-nationwide strike. they want the income tax threshold to be raised to help keep up with double digit inflationed. our latin american editor lucia newman has more. >> here in the buenos aires city airport flights have been canceled until this 24-hour

general strike ends. unlike the last general strike in november, this one has the support and was, in fact, organized by the country's powerful transportation unions. that means that argentina is effectively paralyzed. no planes, no trains, no buses. unions also block the highway access to the capital. they are demanding that the government increase the non-taxable salary limit. but that is not all. >> this is against an economic reality in which workers' buying power is reduced every day because of high inflation. half of the workers make less than half of what they need to maintain a household says this union leader. >> this is the fourth national strike in as many years and clearly the same is put the social agenda back on center stage. although the death of prosecutor

alberto nisman has dominated headlines, they have been fighting corruption, crime and double digit inflation. argentina's trade unions are among the world's most powerful, as they've shown in the past. they're capable of forcing governments out of power. and as these all important elections draw nearer union leaders are telling us that this national strike is just the beginning. >> an inquiry into the deaths of 34 south african miners killed by police in 2012 has submitted it's findings to president jacob zuma. from johannesburg here is erica wood. >> in the week leading up to the shooting ten people had been killed during the strike, including miners, security guards and two police officers. by the 16th of august hundreds of heavily armed police had been

deployed with journalists and cameras watching they began to fire. [ gunfire ] 34 mine workers were killed and others were injure: it was the single worst incident involving security forces in south africa since the end of apartheid. more than 50 witnesses testified including union leaders miners, police and the deputy president. the inquiry wanted to know who ordered the shooting and under the tangled relationship between the government, unions, and mine owners. some observers say what happened had been brew forgive years. >> after 20 years of democracy after the end of apartheid many people feel they have not yet reaped the benefits of democracy. >> south africa has more than 80 strikes each year. most are in the mining sector. last year 70,000 platinum miners stopped work for a record five months. and each time they strike workers ask for the same things.

>> it's about paying workers a living wage, it is about improving continues. >> 80% of the world's platinum comes from south africa, and much of the gold and diamonds, too. the mining companies that extract them are usually foreign owned and operated. the workers and business sector has called for labor laws to be changed, but they want opposite things. >> when the people stood up demanding what it due so them, the government showed its true colors and was willing to spill blood in defense of profits and privilege. >> south africa is suffering from an electricity crisis that is already hurting business, and any labor reform could tip the balance of investment in an already slowing economy. the question is were there any lessons learned from americana

be applied? they want those behind the killings to be held responsible so nothing like that day can happen again. erica woods johannesburg, south africa. >> you can find more about that and other stories that we've been covering on our website www.aljazeera.com. >> had it not sparked fire, this story would be like that of many other low-intensity conflicts over resources waiting to erupt across this oil, gas and fresh-water rich country. back in 2010, the canadian province of new brunswick granted a texas-based company, southwestern energy, licenses to explore for shale gas - in
