hello. you're watching "gmt" on bbc world news. our top stories. the starting gun has been fired. britain's election campaign is under way. prime minister david cameron has left downing street and is right now meeting the queen at buckingham palace. >> reporter: this is expected to be one of the closest, most unpredictable polls in recent history. the deadline looms on a deal over iran's nuclear problem, and key differences still remain. we'll take you live to switzerland to assess the chances of success.

also live as results are expected to start coming in state by state in the presidential election. goodluck jonathan and muhammadu buhari are in the tightest race since the end of military rule 60 years ago. also another crucial day for greece. >> lucy the greek prime minister right here. they've submitted their new reform plans just in the nick of time. now, if these plans are accepted by its creditors and the rest of europe, they'll release the next big chunk of rescue cash. but let me tell you, time is ticking. come april, greece will run out of this. welcome to "gmt." it is 1:00 p.m. in switzerland and 12:00 noon here in london. the last audience with the queen

for david cameron. campaigning for the u.k. general election is finally under way. polling day is in 5 1/2 weeks. at the moment the result is too close to call. well, let's take you straight to phillipa tomas. too close to call, unpredictable. does it feel exciting? >> reporter: it really does feel very exciting lucy. i was standing here on the day that margaret thatcher left office in 1990. then in 1997 when tony blair brought labor government back to britain after 18 years. i think this feels like the most exciting election since then. and we are in the middle of this historic moment. just a few minutes ago, we saw david cameron come out of number 10 downing street get into the car heading off to see the queen. he just had those smiles and nods for the cameras. he's meeting the queen for what could be his last audience as

prime minister. he is the queen's 12th prime minister. he will over the last five years have gotten very used to these audiences. i believe we can show you the live pictures that we have. we have helicopters up in the air. it was a very short journey between downing street and buckingham palace. there you have that lovely wide shot where you can see buckingham palace at the end of the mall. the prime minister is there. not expected to be a long audience. and this is really the formal start of britain's election campaign. with me is political correspondent rob watson. just a reflection on the moment that we're in. >> absolutely. there is a palpable sense of excitement. and i think it is in part because it's looking like an incredibly close race. if i could just say before we get on to that, there's also something exciting. it's the kind of secular equivalent of a sacred moment in a democracy like britain's. you have to pinch yourself and remind yourself that 45 million people are eligible to vote about that. and now the power is in their

hands. but of course, to get back to what we were saying earlier, i mean, the excitement is as in any good story, we don't know who's going to win. if you have to tell anyone it doesn't matter where they are in the world, what makes this exciting is we don't know who's going to win. that's unusual. by and large, some of those elections that you talked about, we knew who was going to win. we knew that tony blair was going to win in 1997. we knew that mrs. thatcher was going to get re-elected several times. now, who knows? >> reporter: rob i want to talk to you more about that and what's at stake in just a few minutes. but as rob was saying to you, as we watched these live pictures and we wait for david cameron to come back to downing street from buckingham palace and talk to us here. there is so much at stake. voters are thinking about the economy. they're thinking about their own well being. voters in scotland are thinking still about whether they should be part of the united kingdom or

not. a lot of voters are very exercised about whether britain should stay part of the european union or pull out. and if david cameron gets back into downing street, he's promised a vote on that. really a lot to think about. then you have all the electoral math and our political correspondent has been looking at that aspect of it. just what might happen in the five or six weeks' time when we get back here and someone's got to go through that door as prime minister. >> becoming the prime minister is simple if you can win more than half the seats in the house of commons. margaret thatcher managed that three times in a row. that's the result from 1983. well over half the mps were conservatives, which meant if they did what she said she could win every vote. tony blair also managed it three

times. that's the 1997 general election result. well over half the mps were from the labor party. but at the last general election david cameron fell short. so he needed the liberal democrats to get him over that crucial halfway line so he could be certain that he could win votes in the house of commons. but what has either of those two big parties, labor or the conservatives, together with the lib dems emerge from the e general election without more than half the seats between them? well, then the smp could surface as a powerful player here. westminster or perhaps the greens or maybe parties from northern ireland. it could all get pretty messy. but then the polls suggest this place is no longer dominated by two big parties like it once was. instead, the politics of the u.k. have become much more complicated. it all means that this general

election could be the first step in a long negotiation to decide who gets to move in there and just how secure they'll be once they get inside. >> reporter: and just to remind you, there's a second reason why we are standing outside the door to number 10. rob watson david cameron isn't the only key politician to come out this morning. >> absolutely. any minute now, i say that maybe advisedly, we're expecting nick clegg to come out, who's the deputy prime minister and also the leader of the democratic party. >> reporter: and here he is. >> and right on cue. >> reporter: yes the leader of the liberal democrat there is. making his own way to the palace. why does he go too? >> he's going to parliament because he's deputy prime minister and because he's a part of the privy council. it's a very sort of senior advisory body. if one reflects about nick

clegg's journey, his longer political journey, he really does have the toughest challenge of the three big parties. the liberal democrats, they have been at least as far as the opinion polls are concerned, they've been taking a real kicking from the voters as a result of going into coalition with the conservatives. so i think there's no doubt that his -- i don't know his entire personal political future is on the line. but so, too, of his party. >> reporter: rob watson thank you very much. you had the dramatic moment there. the helicopters are still overhead. the election campaign getting under way. a lot of excitement here this morning. >> thanks so much. there sure is that extra sense of excitement this time because we simply don't know at the moment who will win. police in bangladesh have arrested two people in connection with the murder of washikur rahman. police believe he might have

been targeted because of writing against religious fundamentalism. the former israeli prime minister has been found guilty of fraud and breach of trust. in 2012 he was acquitted of accepting cash-stuffed envelopes from an american supporter when he was mayor of jerusalem and cabinet minister. an update for you now on that gas explosion in new york last week. two bodies have now been found at the site. it was reported that two were missing from a restaurant hit by the blast. an hour before the explosion, inspectors said the gas work inside one of the buildings was faulty. 11th hour negotiations are under way. the clock is ticking down now on a deadline to get a deal with iran on its nuclear program. foreign ministers from six world powers have been trying to put together the final probably trickiest pieces to get it signed off, which could end over a decade of tensions. however, we have just heard that

russia's foreign minister has left saying he'll only return if an agreement looks likely. let's take you to our chief international correspondent who joins us now from the talks in switzerland. what can we read into the fact that sergei lavrov has left? >> reporter: he was quoted when he arrived yesterday when asked whether he was optimistic. he said, well, i'm not paid to be optimistic. john kerry standing beside him said, well at least you're not paid enough. there is a russian delegation here. sergei lavrov had his meetings last night and this morning. he was at the first key meeting today between the six world powers. there's still a lot of technical detail to go through. of course, all of it is profoundly political. they are very, very close. closer than they have ever been in what's been a 12-year standoff over iran's nuclear program. as is the nature of these kinds

of negotiations, when you're coming down to the wire the posturing starts, the positions start hardening before they come to the last stretch and really indicate whether a deal can be made. that's where we are at this phase. >> what are the key differences right now? >> reporter: well there are many key differences. this is a highly technical document. it's all about how many centrifuges, what kind of an inspection, what kind of break-out capacity will iran have. the united states and its allies want to make sure that iran has about a year before it could actually, if it wanted to pursue a bomb which it says it doesn't, that there would be a year before it would have the capability of doing that. but anyone you ask here whether it's the iranians or any of the world powers what are the key obstacles they mention. one of them is sanctions. which sanctions will be lifted and when. for iran the most important sanctions are the u.n. security council resolution sanctions. for them it's not just financial, the kind which would

give them popular support in iran, it's also about iran's place in the world. it's also political. secondly, it's about research and development. iran, while accepting there will be curbs on its nuclear program, still wants to pursue research and development. they're now discussing how much research iran can do what will be the cutoff period what will be the duration of a deal. so that's what they're focusing on. really details. but the devil is in the details, they always say. this is a place where all the great metaphors are coming into place. but the gaps still being described as really quite important. >> okay. thanks so much for the update. don't forget you can follow her on twitter. do stay with us here on bbc world news. still to come how porpoises use a string of sound under water to close in on their prey. break the ice, with breath freshening cooling crystals.

an update for you now on our developing story in nigeria. votes being counted there. it's being seen as a very tight race between the current president goodluck jonathan and the former military ruler muhammadu buhari. we're expecting some of the first results from now. we should have an idea of who's ahead by the end of the day. let's bring you straight up to date with peter, who's there for us. we were told we might start getting some results from some states right now. has that started happening? >> reporter: hi, lucy. not quite. we were told that at midday on thereabouts local time that some of the results would start to come from some of the 36 states and the federal capital territory. they haven't started to come yet because there's no coalition going on at the national center here just yet. but the head of the independent national electoral commission told the bbc house of service yesterday that the final results

will be announced or are likely to be announced on tuesday, but that this evening we should have an idea of how things are going. but both parties have been coming out to claim that they are leading in the polls. it's causing a bit of tension between their supporters as my colleague will ross now reports. >> reporter: nigerians have to show extreme levels of patience when they were made to queue all day to vote for their president. then there were logistical challenges. now another longer than expected wait for the outcome. here one set of results is rushed to the capital under tight security. as well as some incidents of violence in the north, there was a protest in the niger delta after the opposition said

militias backed by the governing party disrupted voting there. the head of the electoral commission says he'll look into those allegations. he hopes election results will start to come out later on monday but says people must wait for the official announcements. >> the commission warns strongly against premature publication or announcement of results by unauthorized persons and media channels particularly on online sites. >> reporter: these have been the most exopinionspenseive elections ever to be held in africa. the prize, of course is enormous. the winner gets to control the largest economy on the continent. but we are now entering what feels like a dangerous stage. both main political parties are confident of victory, and that's fueling expectation across the country as well as tension. will

will ross, bbc news. >> reporter: well, lucy the winner of the polls might get to control the largest economy in africa, but many people here wonder why anyone would like this job in the first place because if you look at the problems they'll have to meet they'll have to meet with the boko haram insurgency in the northeast of the economy. the nigerian economy heavy byily based on oil with prices falling low. there are no hospitals here. the schools are not enough. a very wealthy country, of course, but that wealth doesn't really trickle down to the ordinary people. whoever does win these elections has a lot of work to do. >> peter, thanks for updating us. the germanwings chief operating officer is in marseille. he's meeting relatives of the victims. an assistance center has been set up to provide psychological and logistical support for

relatives and friends. let's take you to our correspondent who's covering this for us in paris. hugh, of course, there's still so much talk about why andreas lubitz may have deliberately steered this plane into a mountain. such a hard time for friends and families grappling with that. can you first update us as to what you've heard from germany? we know the prosecutor may have new information to share today. >> well we know that the prosecutor is due to give a press conference later today. i understand that the medical clinic where we know lubitz was treated has now handed over its files to investigators. as we know there's been all sorts of speculation in the german media about what happened at the clinic, what he was being treated for. was it depression? was it his eye problem? and the nature of the sick notes, which we know were at his flat and were torn up one for the day of the crash.

but there's been a lot of speculation, not much in the way of hard evidence. maybe this afternoon we'll get something from the prosecutor which will allow us to say with a bit more clarity what medical problem, what psychological problem, if any, lubitz was facing. in the meantime as you say here in france focus goes on remains on the crash site. this morning marseille on this center, which germanwings is setting up for all these distressed relatives who are passing through. >> such a terrible time for them, hugh. what do we know of the investigation so far? how much dna has been collected, for instance? >> well it's a grim sort of body count, really. the latest is about 80 strands of dna have been formally identified. so more than half of the 150 victims. what is happening, of course is that bodies or pieces of bodies i'm afraid, are being brought down to the nearest town

collected there, kept in a place which has not been identified for journalists. it's a very private place. then elements are then taken to paris for identification. the relatives who passed through, the relatives who have been contacted have been given swabs themselves. that allows investigators to make the match. of course, dental records, pieces of jewelry are also being used in this grim but necessary task. >> thanks for updating us from paris. some rather dramatic pictures now we've received from the himalayan region of kashmir that had terrible weather there. lots of rain. it's pretty unseasonable for this time of year. there has been a pretty devastating landslide there. people are saying they think ten people could have been killed when this landslide literally buried houses while people were sleeping. other problems of course crops have been damaged. hundreds of people have had to leave their homes because the rivers as you can see, the levels just getting higher and

higher. police are using shovels to try and locate survivors, but things right-hand turn aren't looking great right now. you can see someone here being rescued. a lot of concerns in this part of india as well and in the himalayas about the rain. right across parts of india, they're experiencing more extreme rainfall than they would normally expect for this time of the year. to denmark, where researchers have discovered that porpoises can adjust the beams of sound they use to hunt. the animals hunt with clicks and buzzes detecting echoes from their prey. researchers showed them switching from a narrow to a wide beam like adjusting a torch, as they honed in on fish. here's more. >> reporter: like many under water hunters, porpoises detect prey using sound, clicking to pick up echoes. when they're chasing one fish

they switch from a click to an intense buzz receiving a stream of echoes as they pursue it. this study shows that they can actually adjust the width of a beam of sound they produce. a team used under water microphones to measure sound from hunting porpoises. this revealed the animal's beam widened, trapping the fish in a broad search light of sound. the scientists say that uncovering these secrets will help them develop ways of using sound as a deterrent to keep porpoises, dolphins and whales from becoming trapped in fishing nets. victoria gill bbc news. now to our top story. british prime minister david cameron has just come back from his audience with the queen. we understand any moment now he'll be speaking from outside number 10 downing street officially now campaigning for the general election. it's incredibly exciting not

only because it always is when an i election campaign starts but this time it's looking to be incredibly closely fought. at the moment it's simply too close to call with the possibility of no party winning a majority. let's take you now to david cameron. >> i've just had an audience with her majesty the queen. until that day, i will be going to all four corners of all four nations of our united kingdom with one clear message. together we are turning our country around. and for your sake your family's sake, the sake of your children and their future we must see this through together. five years ago when i walked through that black door millions of people were unemployed. there was no economic security for families and there were worries about whether our

country could pay its debts. britain was on the brink. five years later, because of our long-term economic plan and the difficult decisions that we've taken, we have more people in work than ever in our history. living standards are on the rise. and britain is more economically secure. of course, we haven't fixed everything. but britain is back on her feet again. a thousand jobs are being created every single day. three quarters of a million more businesses are up and running. and last year our economy grew faster than any other major economy in the advanced world. that means more people getting that job offer and more families hopeful of a better future. and to me that's what the next five years should be about. not statistics but the jobs i want to create for our young people, the taxes i want to cut

so people have more of their own money in their pockets to spend as they choose. the homes i want to build so that people can buy and own them. the better schools i want to establish so that more parents know what it's like to have a great education for their children. and the dignity and security that i want to provide for britain's elderly. ♪ ♪ ♪

this half hour, the starting gun has been fired. britain's election campaign is officially under way. prime minister david cameron has been to buckingham palace and informed queen elizabeth that the u.k. parliament has been dissolved. we'll take you live back to downing street. would you recognize if your child was overweight? a new study says parents are failing to see that their kids are obese, and that's putting their health at risk. aaron is back with a new series for us today. >> yeah, all this week we're going to be looking at crowd

funding. for entrepreneurs, is it really free money? and for their backers, how sure can you be that your donation is being well spent? so today we start in new york where one part of the process is catching some savvy start-ups by surprise. welcome back to "gmt." our top story today is the official start of campaigning for the u.k. general election. the british parliament has been dissolved. prime minister david cameron has just come back from a traditional audience with the queen. let's take you to phillipa tomas, who is outside downing street. it seems the starting gun has been fired. just take us through what he said in his very short statement. >> reporter: well, there were no surprises in the statement because the conservatives want to run this campaign on the theme that they have started bringing britain's economy, as

mr. cameron said, back from the brink. after the recession of 2008 britain, like so many other countries, hit so hard. this coalition government has been a place from 2010 to today. what david cameron said explicitly here is pritbritain was on the brink, we had a long-term economic plan. all the indicators are pointing in the right direction. starting to grow again, unemployment is down inflation is now zero. basically the plea to the voters from david cameron here on downing street was you can trust us, we're on the right track, give us another chance. of course, he's going to be hit back now by all the opposition parties, including his former coalition partner in the liberal democrats saying no austerity has been too tough for this country, and you may be feeling all right, prime minister, but there are a lot of british voters who are not sharing in this recovery yet. >> it does feel like there's

that extra sense of excitement today. not just because campaigning is under way, but at the moment we don't know who will win. what are the polls saying? >> reporter: well in a way it's anybody's to predict. what the polls are telling us and this is pretty consistent, is neither of the two big parties, the conservatives or labor, have the strength at the moment with the polls as they are to form a majority government or any sort of comfortable majority. so what the polls are pointing to right now before the six weeks of campaigning is the possibility of another coalition government who will be invited back to lucbuckingham palace in six weeks' time. we simply don't know whether you could have something again like a conservative liberal democrat coalition or whether labor could come in perhaps with some sort of backing from scottish nationalists.

you spent all that time in scotland when the independence referendum was under way last year. we know that there's been this upsurge in support for the scottish nationalists. they could end up being power brokers. that's even before we've started talking about the other parties in northern ireland or the u.k. independence party here in england or the greens. there are so many parties swirling around and it could be in a coalition situation that every single member of parliament really matters. we haven't got the comfortable assumption of old that either labor or the conservatives is going to form a majority government in britain. we're in very different political waters. >> we really are looking at the changing face of british politics. thank you so much for joining us. pakistan, india, and china are now evacuating their citizens from yemen after a first night of saudi-led

coalition air strikes gwen theagainst the shia rebels. these pictures coming to us in the past three hours or so. some are families arriving back home in islamabad. the saudis suspended their operations for two hours on sunday around the red sea port to enable the safe passage of these people. india also saying it sent two ships to rescue its citizens caught up in the yemen conflict. and a chinese ship is also reportedly docked to evacuate chinese diplomats and other staff. arab coalition war planes have carried out its third successive night of air strikes. on sunday arab league countries agreed to create a joint military force in response to the crisis. well, let's bring now bbc arabic's television editor.

bbc, of course has been covering this crisis in yemen extensively. you've been following this for months now. firstly, what is happening on the ground? have any gains been made by either side? >> well the situation is very chaotic. especially in the main cities. the saudis and the coalition are trying to bomb areas under the houthi control and the former president's supporters just to free an area for president hadi to come back and to use it as a platform for his ruling. now there is nobody controlling the country. you have the houthi rebels. you have the supporters of the president who's not in the country, maybe. we don't have too much information about what's happening on the ground except that the civilian casualties are increasing day after day.

latest reports of the weekend, like 36 people were reported killed in the bombings. the saudis are saying that the houthis are using civilians' buildings to put their air defense weapons there to fire against the airplanes. we can't -- there's no way we can confirm or deny this information. >> were you surprised how quickly the saudis were able to put together a coalition? >> well no and yes at the same time. saudi arabia has always said yemen is a national security issue. it's not only a concern. it's national security. if we look at the map, we can easy see that yemen is sitting on the southern part of saudi arabia. in the southern part of saudi arabia itself you have a shia community that caused a lot of trouble for the saudis. by having a shia-controlled

yemen, this will directly affect the situation inside saudi arabia. this is what they're not going to tolerate. this is the strong message they're trying to say. this is not iraq. this is not syria. this is a matter of national security and we will continue. now, on the ground they will be able to do something. this is another question because after five days of fighting and bombings, the houthis are still managing to expand their operations in many areas. >> complicated situation. not good for civilians on the ground. must be terrifying for people there. edgar, thank you very much for joining us. aaron is with us now with business. how many times have we said this aaron? another critical day in greece. more than a dozen, i think. >> probably more than a dozen. let me explain once again, lucy. thank you. hello there. look it's another crucial day of course for greece because the lenders -- greece's lenders, have new reform plans put forward by prime minister alexis

tsipras' put forward. he got them in just in the nick of time. today is the deadline to secure much-needed bailout funds. greece needs 7.2 billion euros. that's about $7.8 billion. we say now because greece is locked out of the capital markets, meaning it can't go to the international investors to raise money. and with its coffers running dry, the government is pretty much scraping the bottom of the barrel to pay for things like pensions and salaries. let's head straight over to athens. the chairman of the athens chamber of commerce joins us. always good to see you, my friend. listen, me me start with this. there are some reports in the press, in greece which is saying that these negotiations in brussels today are characterized as involving amateurism on behalf of greece. i'm wondering, does this greek government, do they get it? do they understand what they're

dealing with here? >> aaron, good afternoon. first of all, i need to say that this evening, later on in the parliament there is a full session so that the prime minister will inform the other parties as to the detailed contents of these reforms which the greek government is proposing to lenders and eu partners. so this is a renegotiation period that's been going on for approximately six weeks now. so we need to be a little bit more silent until we have the full evidence of what it contains and hopefully by the end of this week, although i think it's going to be rather difficult because of the catholic easter vacations, to have a solution by the end of this week but at least at the beginning of next week we have to have a final settlement of this renegotiation process because on the 8th of april, we

have a sizable amount of money to pay to the imf totaling 450 million, which at the moment is very difficult, even by scraping the barrel to find these funds. >> let me stick with that. you and i have been on these programs. we've been talking about this it feels like for years. we've said it many times before but we're saying it again now. the possibility of greece running out of money by april is there. it's floating around. how dire how serious is this situation right now? >> it is very serious because i need to remind our viewers that we haven't had any funds coming in from eu partners since august of 2014. so we need to have this installment coming in the 7.2 billion in total, as you mentioned earlier on. it is extremely difficult because of the political

instability which was created throughout the period of the snap election. and the fact there was a tremendous delay in actually collecting the due taxes. there is a shortfall as far as public funds are concerned. this is why the government needs to literally scrape the barrel in order to find the necessary funds not only to repay overseas dues but also to fulfill its commitments locally to public sector and the pensioners. >> and very very briefly, i know you said we've got to see what these reforms, what the new reforms entail but we're hearing things like higher tacks on cigarettes and alcohol, more privatization. your gut feeling, do you think there will be enough in those documents, enough reforms? >> well aaron, if we reach more of a political solution rather than a financial solution i think these will suffice. question is whether mrs. merkel and other northern european leaders will provide this

political solution that will give some breathing time to the new government in order to make this strong and deep reforms the country needs. >> okay. once again, we'll wait and see. we'll talk to you soon. no doubt. thank you, mate. we'll keep across all of that. let's talk about this. africa's biggest economy, that's nigeria, is eagerly awaiting the results of one of the most tightly contested presidential elections since military rule ended there in the late '90s. the country has been hit by a tax by the islamist group boko haram in the north as well as falling oil prices. earlier i sat down with a west africa expert from the risk advisory firm and asked her if there was a clear winner to take on the economy between the two main candidates muhammadu buhari and goodluck jonathan. >> the two party parties really manifested before the oil dropped. none of them have presented a

credible plan to respond to the major hit that government finances have taken. >> that's surprising, given the current situation. you were telling me foreign reserve's lowest level in ten years. we have foreign investors fleeing the country basically. i'm just wondering, is nigeria at a crisis point? >> i would certainly say i do think nigeria is at a crisis point, but it's not insurmountmentinsur mount insurmountable insurmountable. we need to take account that the key indices have been driven by political uncertainty. a lot of investors up until now, people could tell you an incumbent president was coming back. i think a lot of the insurgency is driving that investor lack of confidence. >> those results later today. those nigeria election results. millions of people all around the world, they are getting their businesses up and

running through crowd funding. the popularity of crowd funding is soaring, but one part of the process is catching some entrepreneurs by surprise. in the first installment of our week-long series on crowd funding, we have this from new york. >> reporter: the woman being photographed has just finished telling her personal story of struggling with body image. >> that's really pretty. don't move. >> reporter: elisa and her daughter lily are making a feature-length documentary. they're funding their documentary with money from the crowd funding site kick starter. they were hoping to raise $100,000, but they ended up with $135,000. >> another reason why we didn't just go for the one big sum of money from someone else is it really enabled people to be empowered and be part of something and part of a movement or something they care about.

and that's something we really care about. >> reporter: typical of many crowd funding campaigns, every backer was promised something in return. the more money you give the bigger your reward. this can become so onerous for entrepreneurs that some opt to hire outside companies to package and ship merchandise to their backers. >> how many do you think we've done so far? >> reporter: lily and elisa are doing it themselves. >> we've just begun to send them out. i think we have yet to discover some of the surprises that are along the way. but we had to make sure before we even began raising the money that we had budgeted for all the rewards and a big chunk of money as going to the rewards. that was something that was surprising when we were planning the campaign, but we realized we had to do that at the last minute. >> reporter: it's not just money that needs to be budgeted for. it's also the logistics of planning and executing the delivery of the rewards.

>> people have been able to raise the amount they wanted to raise, but they falter on the actual delivery on issues like packages on issues like fulfilling the actual amount of orders. so it's a trivial process. a lot of us think of crowd funding, it's all about raising money. but the back of operations is a lot more important. >> reporter: it may seem like crowd funding sites basically amount to free money, but with that money comes some obligations. so when a successful campaign closes do closes to the public, for the people behind the scenes, there's still yet much work to be done. bbc news new york. okay. follow me on twitter. i'll tweet you back. that's it with business for now. a quick development to bring you. we understand andreas lubitz's medical file has been handed over to investigators, and the prosecutor in the german city will be bringing us a statement

>> reporter: that drone is now in donetsk. their resources are so limited, they're very concerned about losing them or sending them too far where they can't get them back.

>> reporter: so it's another ten kilometers to go until we get to that village, which is quite far. it's not clear how much battery the drone has. if it runs out, then it will be pretty much impossible for them to find it. >> reporter: they found it. he's walking this way.

>> there in eastern ukraine. parents are failing to recognize that their children are overweight until they hit extreme obesity. that's according to in new research here in the u.k. obesity has become the new normal in society. here's our health correspondent dominic hughes. >> reporter: official figures tell us one-third of pupils in their final year of primary school in england are overweight or obese, but it seems many parents are failing to spot when weight becomes a problem. in a study involving nearly 3,000 children in england, researchers found that 31% of parents underestimated where their child's body mass index, a measure of height and weight sat on government scales of

obesity. of nearly 400 children who according to their bmi were very overweight, just four parents correctly identified that weight was a problem. >> i think we don't see what we see every day. what's around us becomes normal. the world has shifted and actually when there's much more obesity around parents just don't recognize it particularly when their families or community are more likely to carry a lot of weight. >> reporter: only at the extremes of weight did parents realize something was wrong, and that lack of recognition was most marked among those who were black or south asian from a more deprived background, or whose child was a boy. researchers say that if parents don't see there's an issue, they may not be willing or motivated to help their children tackle something that can have a serious impact on their health in later life. dominic hughes bbc news. finally for you, president obama has returned from a golfing holiday. he came down the steps just a
