>> the finer the store the bigger the challenge. >> al jazeera america presents: "the life and crimes of doris payne". sunday, 10:00 eastern. >> hello, this is the news hour live from london. confusion over the yemeni president's whereabouts as houthi rebels advance on aden and it's airport. leaders travel to the scene of tuesday's plane crash. driving isil from tikrit. venezuela's restricted to

grocery shopping once a week. heinze merges are kraft. what the mega merger means for the world's two best known food brands. >> there have been reports of gunfire on the outskirts of the city. earlier houthi fighters captured an air base defeating hadi's troops. the foreign minister has echoed the call to help fight the rebels, but the president's exact whereabouts are unknown with some reports saying that he fled by sea and others saying he's still in the city. we have more on the fight for

yemen. >> reporter: it shocked many people but houthies have advanced this far south. taiz yemen's third largest city especially the locals. every day this week they have taken the stand. >> we swear we'll drive out all houthies from taiz and teach them a lesson that they'll never forget. >> houthi fighters reply with gunfire and tear gas several people were killed, many more injured. paramedics say that some of the shooters wore police uniforms. other reports say the security officers themselves, the ones meant to be keeping the peace to join the houthies. these forces are said to be loyal to yemen's long-time ruler ali abdullah saleh who was ousted in the recent up rising

and appears to be backing the houthies. people here are no longer sure who they can trust. the houthi rebel group has morphed from a small unit into a larger force. in september it took over the capital of sanaa. president abd rabbuh mansur hadi escaped to aden in the south and it's in the south where most of the fighting is taking place now. the tribes hearsay they're protecting their region against the rebels. saudi arabia has sent soldiers to protect its border in yemen. the saudi foreign minister had this to say. >> we hope that this can be done peacefully. if it is not done peacefully certainly countries of the region and the arab world will

take the necessary measures to protect the region from the aggression. >> they insist they're fighting for a fair distribution of wealth for everyone, not just shias or their own community. some people in the south don't believe them and aren't taking any chances. these volunteers are grouping in large numbers to take on the houthies with guns tanks, and ammunition. al jazeera. >> the adviser to the last three prime ministers. we saw some of the efforts to fight back against the houthies but they seem to gain ground very quickly at one stage in the airport, now it seems that they got the airport back. what are the chances of hadi supporters regaining the upper hand. >> i think the position right now is very difficult.

people have got to understand and there should an message that more half of the country is not under their control at large. the vice president went, and at time these people did not want to bring down aden. i think the similar if the the president would have a strong base so if the saudis want and the gcc want to push back against them, we now know there is now resistence. this is very close they might

be able to reach the saudis. >> we really don't know what has happened to president hadi. it seems that he left his compound there are reports that it has been looted. if he does not make an appearance again does that make it more difficult. >> that's why he should have a base again if he appears and there is more fighting, 60% of the country is still not under the houthies this is quite a far area from them. 700 kilometers from aden, there he can stage a comeback so people can see him. >> is the come back predicated on the military-- >> not military, but clear the message. the most defining thing is the

air force. as we've seen in the past five days if the military air strips were hit this would an strong message for his people to go back to the dialogue table again. >> why do you think that the dialogue unraveled so quickly? what's happened there. >> i don't know, sorry to say it looks as if the yemeni government--the yemeni people have been sold out. is yemen being thanked as a sugarcoating? we feel they have been let down by the international players. but with the original players

it will let them down, well done iran. go for aden. so we should say congratulations for the iranians. if the saudis don't really understand, the whole situation will not be stable. everybody should know that that this important area. and i know americans may have sold us out but there is oil passing through. will the egyptians be happy about this? i don't know. but it's more of a concern of the saudis and gcc at large. >> we will put your point of the americans selling the yemenis out, they may disagree with that interpretation, but thank you for your views on that subject. >> thank you.

>> air crash investigators still don't know have a clue of caused the crash on tuesday. the leaders of france, germany and spain have flown in to show their support. the day's development, the cockpit recorder, badly damaged showing the severity of the impact. the device is now in paris and they say they've been angle to able to recover some information from it. the data recorder is still missing. >> brought together by tragedy the leaders of france, germany and spain arrive in this small town in the alps. they've come to pay their respects to the vickers of the plane crash and to get the latest on the investigation. their presence underlines the

international disaster. >> we need to understand what happened. we must do so. we owe this to the families of the victims and the countries involved. >> all day long helicopters have been ferrying searchers to and from the crash site. the wreckage is scattered over the area of eight football fields. nothing could be recognized as a plane. it may take weeks for investigators to examine the whole of the crash fight. it is still unclear what caused 9525 to plunge from the sky but this voice recorder may hold some clues. >> there has been some difficulty reading the data. we've been age to extract some

information from it, but it's a little bit early to say what happened. >> 150 people were on board the aircraft at the time of the crash. no one survived. retrieving and identifying the bodies is a grim and painstaking task. >> the identification of the victims is essential. we have to start with that. we owe that to the family of the victims. it won't be done in five minutes. it will take weeks. and everyone should be aware that this will take a long time. >> darkness has descended on day two of this operation during which the casing of the flight's data recorder was found but we're still no closer to answering that question, why a well-maintained plane flown by experienced pilots in good weather crashed killing all those on board. >> the u.s. coalition airstrikes is underway with the offensive to retake tikrit from the

islamic state in iraq and the levant. iraq requested u.s. air support for its operation to recapture saddam hussein's hometown. the iraqi government forces have been trying to push isil out of tikrit for the past three weeks. going now to tom ackerman in washington, d.c. what more can you tell us about that operation? >> well, it's interesting that prime minister al abadi. >> it said that operations were on going and there was a communication that said this involved both airstrikes and surveillance for the iraqi

force. it's clear that the iraqis thought they would not be able to break out of their one week lull in the operation without being able to capture tikrit without this amount of air support. >> originally they said that they were happy that the iranians were involved in this operation, and taking a backseat, if you like. what's changed their mines to join in on this one? >> well, it's not clear but the american spokesman had been clear in saying there has been absolutely no coordination with the iranians on the ground, and they're only deal with the iraqi government forces. what is also interesting, some of the shia militias have been

quoted specifically saying they do not want american support that they can do this operation to oust isil by themselves, and that the americans support is not desired and rejected. there is a difference of opinion with the central government in baghdad. >> thank you very much, indeed, with a live update from washington. >> over the border isil fighters said to be among rebel forces who have taken the city of al sham. the battle has been raging for four days. they have listed it as an endangered site since. >> nigeria will close its land and sea borders until after saturday's vote. and landslides kill nine and

destroy hundreds of homes in peru. and india looks for its place in the cricket cup final. >> two governments battling it out have resumed peace talks in morocco's capital of rabat. the u.n. backed government has based in tibruk, the house of representatives will still be based in tibruk. the presidential council will look work in the interim period.

there is still little trust for the struggling factions looking for power. >> more casualties of war. they continue to bury their men. two brothers and their cousin, these men died fighting groups affiliated with the islamic state in iraq and the levant but libya has another war front one where libyans are killing each other. misrata is part of the libya dawn coalition which believes their rivals are linked to moammarga muammar qaddafi's regime. >> we're fighting against those groups, and we're still insisting that we'll finish our battle, but still we're offering our hand for negotiation. >> the future of libya is ac mandarin stake. these university students grew up under a dictatorship. they fought for freedom but after that libyans failed to

unite. >> we want security. we want our country to be like any other. we have been dieing in the thousands. every day we lose someone because of the war. >> people here are hopeful that the rival factions will be able to reconcile and agree to a deal at u.n.-brokered talks in morocco. but they also say bringing peace on the ground may be the real challenge. >> if there is an agreement in morocco between libyan dawn and dignity, the question is can it be implemented. that's because these groups have been watt war. not one group can control. >> peace and security, that's what libyans want. a lot of blood has already been spilled. libyans have been at war with each other. there is a dangerous power struggle in this country. >> none of the factions have been able to rule this country

alone. now they're being asked to share power to end the conflict that has caused so much pain and suffering. al jazeera misrata. >> trial of two al jazeera journalists in egypt have been adjourned since april 22nd. mohamed fahmy, baher mohammed have already spent 400 days in jail with their colleague peter greste. now they're out on bail, but now they're accused of aiding the banned muslim brotherhood. charge that they and al jazeera deny. a suicide car bombing in heart of afghanistan's capital has killed seven people and injured 37 others. it comes after prime minister ashraf ghani met with president barack obama to slow down the

troop withdrawal. well, the closure of nigeria's land and sea borders during the election is indicative of the electoral commission is on call to hold the election on saturday. there have been fears that people are jittery about the prospect of another postponement. you'll recall that the election was postponed by six weeks because the military said it needed more time to fight boko haram. this announcement by the ministry of foreign affairs indicate that everything is on course. that the election will go ahead. it came with the approval of president goodluck jonathan, and there is a line in there making sure that non-nigerians do not participate in the process. authorities are concerned about foreigners coming into the country during the election process. now in a separate development a

court has been adjourned that was hearing evidence against the main opposition presidential candidate. there were attempts to try and disqualify him from running in these elections on the basis he has not been able to produce the secondary school certificate, a requirement in the constitution if you're running as president. that case has been adjourned until the end of april. he will be able to participate in saturday's poll. >> now nigeria's government has denied reports that 400 women and children have been kidnapped. the residents say that boko haram took children and their teachers from primary schools and used them as shields when they were force in their retreat. last year the armed group abducted 300 school girls from the town ever chibok, and most of them are still missing. we go to an expert on boko

haram. let's go back to the report of the disappearance of 500 people from damasak. first the government admitted to it happening and now they're denying it. what's going on here? >> i think we need an independent confirmation regarding these reports. sometimes these reports are very difficult to confirm, but sources on the ground saying that 500 people have gone miss from damasak. i know that damasak is very close to niger and it is very difficult sometimes to provide security. >> so what if boko haram has taken these people? what is their idea? what are they trying to do? >> they're looking for soft spots that even if these territories have been taken back by nigerian military, they are still active. they are still a threat.

that's number one. number two they're still looking for publicity. that's why they're targeting aspects that are easily attract international attention. gender-based violence against women and children. this will get the attention of the international community. this shows that boko haram is still alive and active. >> how much support to they have? >> i don't think that they really have any serious kind of support. most of these villages are really not protected. they're very very vulnerable. that is why boko haram is able to infiltrate: speak the language. they know the area. they ngo have the local content and knowledge, and these villages are very vulnerable. >> do they pay people to shelter them? how do they sort of protect themselves? what is their method?

>> it's very difficult. the only thing for people to find security in other places. but at the same time, boko haram will pay some of their fighters. they're able to pay as $700 a month to their fighters, particularly in a country where the minimum wage is just low. they have the ability to access recruit from young unemployed people. >> at the moment is it possible that the government has denied that this has happened because they don't want these kinds of stories in the international media or national media at a time when the election is coming up. >> at the moment, they have serious concentration on the

election. the international attention is on the election. at the same time looking at the context with that kind of news coming out for a government that could not defeat boko haram for six years. asking for six years extension. that kind of news can undermine the effort of the government. they have really made some gains, but that kind of news can undermine what is happening and i think you should expect that type of narrative to come out. >> thank you very much. >> thank you. thank you. >> south sudan's government said it's investigating u.n. reports that dozens of children were abducted last month. unicef say children continue to be at risk of recruitment. there are 12,000 child soldiers. >> this is home to roughly

24,000 people, including many children who haven't been going to school since fighting began a little over a year ago. the children are also threatened with abduction. much they recruit child fighters in a country. stephen prepares for his final school exams. he's worried he has not ready. his town has not seen any fighting for a while. his >> we are afraid if we go into town, even to school we might be recruited into the armies. >> united nations peace keepers escort 150 students from the camp to their examine center in town teachers here tell us that the students need to be better prepared. >> they give it their best any way. and

>> just this year dozens of young men are said to have been abducted from a center not far from here. it makes those living in protected areas afraid to go back to their homes. >> unicef reported that abductions, 89 teenage boys, maybe more, are said to have been taken by a militia group allied to the government. we were not allowed to go there. >> some of those children are returning to their homes either for meals or short periods of times, in some cases even to sleep. they are then required to go back for military training during the day. >> commanders say they're investigating but overall they have been successes in child protection while militia group allied to the government has relieved 600 children in the past two months. but the united nations say that there are still around 12,000 minors in the warring armies, and the allies militias. >> it might seem like, the

opposition. there are child soldiers in their ranks. but if you look at the condition that the country is in, sometimes for them to be in the army is safer than for them to be out there in the civil population because they will be victimized. >> if this these students pass their examines they'll go to secondary schools and they'll feel fortunate that they're learning and not fighting. >> still to come in this hour we meet the mexican farmers who have abandoned their fields to demand better play. plus dancing to a new tune. the greeks put their independence on show as they continue to stand up to europe. and why this golf course is causing an olympic-sized controversy.

>> sunday. you know his music but what about the man? >> i was given a gift. >> up close and personal. behind the scenes of the biggest hits... >> she was a troubled girl. >> brightest stars... >> kids don't want to "own", they just want to "play". >> and the future of music. >> the record business is in trouble. >> every sunday night, >> i lived that character. >> go one on one with america's movers and shakers. >> we will be able to see change. >> gripping. inspiring. entertaining. talk to al jazeera. sunday, 6:30 eastern. only on al jazeera america. >> a reminder of the top stories on al jazeera. houthi rebels close in on the

southern city of aden on there has been gunfire on the outskirts of the city and houthi had captured the airport until it was retaken by troops loyal to hadi. leaders visit the crash site in france that killed 150 people. u.s. army sergeant to abandoned his post in afghanistan and was taken captive by the taliban has been charged with decertification. bowe bergdahl was captured in 2009. he was released last year in a controversial prisoner swap. he has been found guilty of the misbehaving and and could be

sentenced. >> panic in the town. people running in every direction not knowing where to go. there is an alert right now authorities are telling people that they have to leave because there might be another mudslide coming this way. >> this woman and her children run for safety. they're terrified. this man can hardly catch his breath. >> they say the reservoir has collapsed and the water is heading this way. >> the police guide residents to go up the hill. >> we're telling people to go in that direction. >> but then calm returns. a police patrol rolled by saying it was a false alarm. residents here are on alert way into the night.

carrying shovels and picks. people are beginning to clean up the debris. they're afraid that a home left in a ravine might collapse. >> look at the hole it's made. seven meters deep. power lines are down in other areas. >> a series of powerful mudslides destroyed dozens of homes and vehicles in the eastern region in central peru. to save their lives people ran and climbed on trucks as the water levels from the rivers rose. authorities say there are children among the dead. ask you teams are sending tents water and blankets for the victims. in some areas drinking water has been cut off. power lines are down. and police say several people are still missing. government authorities say the main supply route for the capital will be blocked for five or six days. police and army you wants have been deployed in the region,

dozens of trucks remain stranded throughout the night they say the alarm is far from over. this has happened before, and with all the rumors we're hearing we are alarmed. >> many like him remain on alert alert. forecasters say for rings rains will continue to fall until the end of the week in ten provinces, leaving this area especially vulnerable to more mudslides. >> striking farm workers are holding talks with land owners in one of mexico's important agriculture regions. the workers are demanding better pay and conditions, but the owners say that their hands are tied. tied. we have more from san quintin valley. >> farm owners are due to meet

with workers. these arm workers are paid $8 to $10 a day and live in basic and camped conditions. what they're demanding is $20 a day and better working conditions, and they say they can't afford to wait any longer. >> our demands are simple. they are the same thing that thousands of us have been asking for for years. but no one has wanted to find and answer. no one is worried about us. now we're tired of going hungry, low wages we've sided to rise up. >> the produce here is exported to the u.s. but even with that they say they don't earn enough from the fruits and vegetables that they're selling but it is in the interest of both sides to come together because the harvest here is currently going to be lost. >> supermarkets are introducing sweeping new measures as food

short shortages continue in venezuela. shoppers are allowed to shop on certain days of the week. >> private supermarkets have introduced a new system. with this new system the idea is that venezuelans can limit their shopping to just one day according to their i too. for example on a monday, people whose id ends with one or two would be allowed to buy the items that have gone scarce. like milk, sugar or even flower. the government is also planning on introducing fingerprint scansers. this will control speculative shopping or hording. the idea behind this is to stop what has become a problem. with people shipping out close to 40% of what the country

imports across to the borders to brazil columbia and even by water to the caribbean. people whose i.d. ends in two and three have hit the jackpot. they've come to the supermarket to discover there are two of the items missing from most shelves: : soap and fabric softener. >> heinze owned by warren buffet is buying kraft foods whose stock is now soaring. >> it is a marriage of ketchup and jell-o and convenience. the merging will create the fifth largest company in the world. it will create cheese jell-o, coffee and peanuts. heinze is best known for its catch up and it's orida. the news sent kraft stock up

30%. the deal bringing together two century-old companies together. >> the 3 g group has capitalized so it is able to modernize any sort of department of industrial area of kraft foods. so this marriage is good because one has a lot of capital. the other is looking for a sort of reorganization which is a re-energization. >> it address a huge company one that can save money by product lines and manufacturing. but shifting appetites have consumers have moved away from processed foods, that is largely what both companies make. kraft hinds will maintain

headquarters where heinze is based. >> in myanmar a protest march turned violent. the crackdown has raised international concern over return to tactics used by the former military government. >> reporter: the student protesters detained since they were arrested after their march 10th rally arrived at the court in a column of trucks. their families and other activists were there showing their support for the detainees. the students were rallying two weeks ago against an education bill one that limits students' freedom. but the rally was brought to a violent end when baton-wielding police smashed back as protesters tried to push through police lines preventing them from continuing their march. the violence continued on and police even attacked a truck used by the students. the action by the police caused

international condemnation, but the government said that the police action was justified. back at the court the parents of those detained said they don't even know what charges their children face. >> i want them to be lenient on the children and free some students who don't need to be detained. >> as the world watches the images of this violence some are beginning to question how well the reforms in myanmar are going. earlier in the month the united nations expressed concern over the government's commitment to human rights. but the focus of those outside of the court right now is to see their children are set free. scott haidler al jazeera, bangkok. >> benjamin netanyahu has received a former request to formal request to form israel's next government. he'll have six weeks to put together his next coalition.

his re-election was largely due to the right-wing rhetoric in the run up to the vote. jordan will be the third arab state to pursue nuclear energy. it has just signed a deal with russia to build two nuclear reactors. we have these reports. >> reporter: it's taken years of research and negotiations to get to this point. jordan and russia have signed an agreement worth $10 billion setting the legal basis for building jordan's first nuclear power plant. russian state owned nuclear firm will build a two-unit power plant with 2,000 mega watt capacity, the first of which will be operational by 2022. over the last few years energy-poor jordan has sunk in-depth. turmoil in egypt has cut off its supply of cheap natural gas and

the conflict in iraq has done the same with oil shipment from there. jordan spends billions of dollars generating electricity each year now the government believes nuclear is the way to go. >> nuclear power is one of the solutions. >> but there is widespread opposition to building a nuclear power plant here not only from civilians and environmentalists who are concerned about the planet's safety, but from politicians, too. parliament will vote on a law for the new deal and will be under pressure by the government to approve it. three years ago jordan's parliaments approved a recommendation to suspend the country's nuclear program on the grounds that it was hazardous

for the environment. this has been ignored with the signing of the new deal with russia. the government adamant about producing it's own energy, and there is little lawmakers can do to block this project. russia has 70 years of nuclear energy experience and maintains it's reactors are the world's safest. >> among the preparation work has been carried out including studying different sites. and therefore i can guarantee the nuclear pow power plant for jordan will be built for safety. >> jordan i want ports 90% of imports 90% of its normal needs. jordan wants to become less dependent on foreign energy.

>> two top ukrainian officials have been arrested during a televised government meeting. they are under suspicion of extorting bribes. hours earlier a powerful regional governor was sacked. it is part of a wider anti-corruption crackdown. greece is celebrating its independence day. they tried to use the event to forget about the ongoing economic problems caused by huge debts. we have reports from athens. >> the hardware is european. the independence it up holds is greek. they have recently been at odds. europe demands austerity in return to financial aid putting greek independence at doubt.

prime minister alexis tsipras recently smoothed over european tensions with chancellor angela merkel. >> there are moral and honest leaders who helped us through the woods and into the clearing. our prime minister looked the germans in the eye. he didn't beg. >> it's an opportunity to feel proud that we're greek. lately people have been trying to make us feel bad about ourselves. we'll fight through to better days. >> debt has clouded greece's relationships before. like today greece had trouble paying it back. >> then as now europeans went through a phase of disillusionment with the greeks. many who traveled here to fight for their freedom lost faith in

their cause. greece nearly fell back in the hands of the ottoman empire. but ultimately the on again-off again relationship between greeks and europeans held. the new government vows to bring honesty back into politics. >> today we remember that nothing has been given to our people for free. everything was fought for. when people stake their claim in a determined way no matter how strong their adversary if right is on their site there is no limit what they can achieve. >> greece wants to dictate their own fiscal discipline. those details are due next week. >> we have sports and the cricket cup. plus 250 underwater specimens go

on display.

>> we go to sport. >> thank you very much. in a few hours time australia will take on india in the semifinals in the cricket world come. it's the 23,478 one rankings against the defending champions. the winner will face new zealand on sunday. australia would look to get some revenge over india. india knocked them out of the

last semifinals. >> i thought india would be tough to beat because they've been in condition for so long. they've played a lot of cricket in australia and they've shown that in this tournament. >> yes the indians have been in australia sips february. and they turned it around in the world cup winning all seven of their matches so far. >> and it's been tough but you know, if we look at the way the last month has gone, it's been really good. we have to make the last four months we spend here by winning the semifinals and the finals. we don't mind staying for five months. >> now while the out come of the match may be too close to call, one thing you can say about

india and australia they're feisty affairs. the most notorious incident came in february 1981. the indian captain said that he was verbal by abused. that prompted him to order his batting partner to follow him off the field. and then they would abuse indian player dravid and. the most notorious episode came in january 2008 where he was called a monkey. he was banned for three test matches, and then his punishment was revoked. david warner was accused of racially abusing all he did was to ask him to speak english.

the club is taking a break for the next week and a half with international football taking center stage. there have been important qualifyiers. germany held at home by australia. they took the eighth equalizer to prevent a defeat for the world champions. bendtner would score a hat trick against the united states. he insulted the french nation and was heavily criticized for it. he said he had no intention of leaving. >> i wouldn't have come to france if i didn't like it and i wouldn't have signed a new contract and played this long if i didn't like it.

all the things being said is just to drag me down. i'm happy at the top. >> golf is back in the olympic games after a 112-year absence it's finally cleared the last legal hurdle. a brazilian judge has rejected a second attempt to halt construction on the olympic golf course. many are unhappy that it's being watered during rio's current drought. less than 500 days until rio 2016. organizers are insistent that today's building sites will be next year's impressive venues for the games. but there is a halt ahead for one of the main olympic venues. >> idyllic from above but up close it tells a different

story, in 500 days it will be hosting olympic sailing events. >> we expect and trust that we will have the bay and it's waters ready to host athletes from the entire world and these waters will be equal for everybody. >> at this market shopping center in rio items fished out by divers have been put on display to raise awareness to the environmental issues associated with the problems. the bay receives the majority of the city's raw sewage, and as part of its bid the city would clean up 90% of it, but the mayor admits this goal is no longer achievable. >> it's obvious that it is the responsibility of all of us, all of us meaning the government. society has also it's part. i think we missed the opportunity to clean the bay. >> west of the city at the main olympic park officials say all the venues are on time and on

budget. >> different than the other games, 60% of our budget comes from the private sector. so we're using the public-private partnerships to reduce the high cost of public money. so that's our on our part. we're delivering the games with a huge legacy, and savings public money. >> after the rush preparing for last year's fifa world cup in brazil officials are adamant that they won't face the same problems. test events will start in july, building towards the opening ceremony on august 5th next year. everyone hoping that it will be smooth sailing until then. al jazeera. >> now, in australia going into the cricket world cup against india, but they have the support of billion indias and one fish. the in the indian city of chinai

they have picked australia ahead of the game. he has picked the winner before all knock out games so far. will australia knock them off their perch? >> you can blame my producer for that pun. >> indeed. it wasn't a perch. staying with the fish thing we'll talk about the rain forest at coral reefs occupying 1% of the ocean floor but hold a quarter of marine species. we go to a new marine ex-addition in london that highlights why they're important. >> it's a window to underwater world. it does not often feature living objects but this new show is a chance to look into the past and the future. the teams brought together corals that are nearly 200 years old with examples of diverse creatures that make reefs their home.

the aim is to highlight the role reefs play in our ecosystem. >> they are dependent on the coral reefs for their economic well-being either by fisheries or using them as tourist industries or has coastal protection because coral reefs are build up of limestone so they can break the waves from storms and protect cities from storm damage. >> one of the highlight of the exhibition is this, a virtual dive, and it means you can get as close as possible to the coral without actually being on the sea bed. and it does give you a good impression of how much maureen life the reef supports as well. experts say over the last 35 years half the world's coral reefs have disappeared, often do to oceans becoming more acidic through pollution. but new activity like dredging near australia's new barrier reef is worrying environmentalists, too. these pictures come from a huge

underwater project. >> three cameras are synced together the computer that controls the cameras and then the underwater-propelled vehicle allows the diver to move along the reef crest. the cameras take pictures every few seconds so over a typical dive we'll record the health of the coral reefs over two kilometers. >> which gives you an idea of how pain taking it will be to happen all the world's reefs but they say it will be worth it. al jazeera london. >> a quick reminder you can keep up to deet with all the news at our website. the address for that is www.aljazeera.com. that's it from me, lauren taylor for this news hour. i'm be back with another full round up of the day's news. join me for that. thank you very much for watching the news hour. bye for now.
