Milestone. The u. N. Report says at least 6,000 people have been killed in the conflict. The children still at risk of ebola in liberia. We take you live to west africa to look at how much progress has been made in tackling the virus in the countries worst affected. Welcome to the program. Aaron is here looking at cutting Edge Innovations at the worlds biggest mobile phone expo. Its all about the new mobile congress. Weve got the latest between the big battle between samsung and apple. Samsung launches its new galaxy 1 s6 edge device. But is its threesided device enough to wow the competition. And competition from chinese and american rivals. Welcome to gmt. It is midday here in london 7 00 a. M. In washington and 3 00 in the iraqi Prime Minister salahuddin where a massive military operation is underway right now to retake the area from Islamic State. Iraqi forces are trying to recapture tikrit saddam husseins home city north of baghdad. This represents a big challenge, though for iraqi troops. Were getting reports now that Islamic State are using human shields to slow their advance. The Iraqi Government says around 30,000 troops are involved in the operation. That includes around 2,000 sunni volunteers, as well as shia and kurdish militias. Salahuddin was captured by Islamic State last summer during a push that also saw the jihadiists take mosul, the countrys second largest city. Reporter this is the biggest fight back yet against i. S. Thousands of Government Forces have been pounding i. S. Positions around the city of tikrit. Theyve been strengthened by sheer militia and local sunni tribes opposed to the extremists. Iraqs Prime Minister tried to address fears of reprisals against tikrits sunni population. I call upon you and all other commanders to deal with citizens well. Our goal is to liberate people from the oppression and heroism. We should protect the citizens and their properties. Reporter theres very real concern that this offensive will reignite sectarian conflict. Shia militias have promised to avenge the execution of hundreds of shia operating room recruits in the early days of the i. S. Advance. If the government takes back tikrit, next in its sights is mosul. These are i. S. Militants last year triumphantly showing off captured American Equipment there. In anticipation of an assault on the city aid agencies are already preparing for a mass strike of refugees. There have been several failed attempts to reclaim tikrit. If these forces succeed, it will be a big boost to government morale, but the government is a highly symbolic and strategic prize that i. S. Will fight hard to keep. Emily buchanan, bbc news. Lets take you to baghdad now. We can talk to former iraqi politician hamid alkafiy who is there for us. Thank you for joining us sir. A massive operation underway right now, as were talking. Why has the Iraqi Government made the decision to begin this operation at this moment . Iraq feels they have the strength now, the International Support, the local support. It has training. So it needs to move. In fact, its overdo because isis has been in charge in control of this city, as well as other cities since last year. So its really overdue. But iraq feels that it has the strength to go forward and liberate the city. So you believe the iraqi troops are ready for this . Because its very ambitious and many people say there hasnt been enough time for them to develop the skills they need. Well i dont think its very ambitious, because tikrit and salahuddin, the whole province is not totally in the hands of isis. Some parts of it are in the hands of the iraqi army and local volunteers. So its going the iraqi army will complete the takeover of tikrit and hopefully defeat the terrorists. Is iran involved in this operation . The ambitious sorry . Is iran involved in this operation . Iraq, iraqs friends are all involved. I am sure. Obviously, i cannot say if iran is involved or not. This is a question to be asked for government officials. I am not. But certainly, iraq feels it has the strength and the weapons and the support, local and International Support, to move forward and defeat the terrorists. What about what will happen on the ground given the warning today, the militias who are involved to not, for instance burn peoples property to not loot the sort of behavior that hes obviously concerned about . Yes, of course there is some concern, but, you know, i dont think this will happen, if an incident or two happens, then thats that cant be dealt with. But doesnt the air strikes that youve got the military youve got Paramilitary Forces on the ground who are not able to be controlled. True. These are volunteers who want to liberate iraq from the terrorists. Obviously, there are, among them, those who are looking for personal gains, but, you know, they are, they are watched and the Prime Minister has warned them that nobody can if anybody tries to you know, break the law, then he will be dealt with severely. So i dont think its a major concern, but the Prime Minister had to make things clear, to everyone that this is a war against terrorism and the army and the volunteers must be careful not to arm civilians or civilian property. Briefly sir, before we finish, what do you know of americas involvement in this . The americans have got their advisers, who have arrived in iraq you know, some time last year. And i am sure their advice has been taken and iraq wouldnt have moved without International Support and americans are first. And im sure their advice okay thank you very much for joining us. Thank you for joining us from baghdad. Lets get up to date some other news. We are getting reports that say at least 19 christians taken captive by Islamic State fighters in northeastern syria have now been released. All are said to be older than 50 indicating that age may have been a factor. The militants are Still Holding about 200 others who were kidnapped during raids in villages last week. Los Angeles Police have launched two separate investigations into the shooting of a homeless black man by officers. Police said they would not comment on the killing while the investigations were continuing, but dramatic footage shows the officers grappling with the victim. A voice is heard shouting drop the gun, before five shots ring out. Estonias Prime Minister has won a general election. It was dominated by economic issues, but also security concerns as russias actions in ukraine. His reform party secured 28 of the vote narrowly ahead of the central party, which is supported by most russianspeaking estonians and favors closer ties with moscow but his coalition has lost its overall majority. The israeli Prime MinisterBenjamin Netanyahu, is in washington ahead of a muchanticipated speech to congress on tuesday. Mr. Netanyahu was invited to speak by the Republican House speaker, john boehner. His visit, though has further worsened already strained ties with the obama administration. The israeli leader says hes hoping to boost support at home ahead of key elections in two weeks time. Lets take you straight to jerusalem. We can join our correspondent there, kevin conley. Elections just around the corner. Whats being made of this visit . This is a moment where all different strands of a story feel like theyre being knotted together all at once. So you certainly have the israeli elections and mr. Netanyahus desire to show his security credentials on the global stage. But he also believes that this is a crucial moment in the negotiations between the International Community and iran over tehrans nuclear ambitions. He feels he has a lot to say on that subject and congress is his chosen platform. Its also because of the way the whole story has evolved, become a pretty important moment in relations between israel and the United States as well. So all of those things are taken together to make this moment matter. And of course that also means, philippafill its a very very important moment for Benjamin Netanyahu, as a politician himself. After all the fuss leading top this speech he better make sure its a pretty good one when he stands up to speak to congress tomorrow. Given some of the comments that have been made, that has susan rice saying that this vis is actually destructive to u. S. israeli relations, what are we expecting him to say to congress particularly about iran . Mr. Met yannetanyahu would say, of course hes not going because of israeli elections, hes not going to seek political advantage, he is going because he believes theres an emerging possibility that the world powers the p5 plus 1, led by the United States, who were talking to tehran are preparing to do what he regards as a bad deal. A deal that would leave iran much too close to getting nuclear weapon. This is one of the signature things that Benjamin Netanyahu like, so he would see himself as having an important contribution to make. The white house, of course the obama administration, is hopping mad, frankly, because they see this as mr. Netanyahu, effectively, trying to rally conservative opposition in the United States, to a negotiation being led by the white house, by the obama administration. So theyre angry for that reason. And they also sense, i think, that conservatives in congress led by the republican speaker john boehner, are deliberately giving mr. Netanyahu a platform to give him a leg up in advance of both israeli elections. Of course, well be watching that speech all the way over in washington, back here in jerusalem, too. Kevin thanks for joining us from jerusalem. Do stay with us here on bbc world news. Still to come, Prince William is on a Charm Offensive in china, but he did raise some real issues with xi jinping.

Now says the conflict has claimed at least 6,000 lives. To underscore the ceasefire of the Ukrainian Government and the prorussian rebels the Ukrainian Government says another of its soldiers has been killed within the last 24 hours. Maintaining that ceasefire has been a focus of talks between the u. S. And russia on opposing sides, of course. John kerry, the u. S. Secretary of state has tweeted this picture today, of his meeting with the Russian Foreign minister Sergey Lavrov. The usual broad smile is missing, as you can see, and look at what john kerry tweeted. He said the pair had helped discussions on ukraine, syria, and iran talks. Well, that meeting was held in the swiss city of geneva. Both men are there addressing the u. N. Human rights council. Now lets talk to imogen. Just look at the frosty look on both of the two mens faces. Do we know what theyve talked about . Well they talked about ukraine, where we know there are great many differences between washington and moscow. And they talked about ukraine in the context of the latest devastating report from the United Nations, in excess of 6,000 people dead, hundreds of thousands, the u. N. Said cowering in basements without food or water being shelled mercilessly. The u. N. Says. So, of course, when Sergey Lavrov and john kerry got up to talk to the u. N. Human rights council, these were speeches in public. They then gave their public accounts of ukraine. And as you will hear and see now, what they chose to focus on was rather different. Well start with what Sergey Lavrov had to say. Translator the grave humanitarian situation in the donbass should be given the highest priority. To ensure the fundamental rights of its people the Ukrainian GovernmentMust Immediately lift the de facto blockade of this region restore economic ties payment of social benefits Banking Services and the freedom of movement between the donbass and other parts of the country. Do not allow yourselves to be misled. In crimea and in the separatist controlled areas of eastern ukraine, men, women, and children are being killed. Theyre being tortured. Theyre being raped and sexually assaulted. Detained arbitrarily, abducted for ransom forced into labor, prosecuted and persecuted because of who they are and where they worship. And that is what is happening. And its up to the hrc to shed light on it. And to help to hold accountable those who violate those human rights. Well john kerry there, highlighting what he sees as the very dreadful situation in eastern ukraine. And no doubt that washington does hold russia partially, at least, responsible for the conditions there. And we do have the United Nations report saying there is credible evidence that heavy weaponry and foreign fighters have been crossing the border from russia into eastern ukraine. But, in fact just before i came on air to talk to you, i talked to the head of the u. N. Human rights Monitoring Team for ukraine. And the thing that is concerning him most he says is that now, this shaky ceasefire should hold, give the hundreds of thousands of civilians some space to breathe and go back to their normal life and in the longterm, perhaps, heal very bitter divisions. Imogen thanks for that. Lets look now at what life is like for people in eastern ukraine. The u. N. Saying as imogen just said, hundreds of thousands of people have been now for months without power, heating, water, and food. And even where life continues somewhat as normal there have also been significant changes. Rupert wingfieldhayes has been one to mariupols new high schools to find out about newly created lessons in ukrainian patriotic education. Reporter this is the Biggest High School in the city of mariupol. Weve come here this morning to witness something very new, which is patriotic education. A little earlier, all the kids in the school lined up here in the hallway to sing the National Anthem. Then they go for an hours lesson on ukrainian nationalism, ukrainian history, and learning about patriotism. Someone who comes from britain, its very strange, because we dont tend to wave the flag and talk about patriotism, but here its a very very important subject, particularly because of what is happening with the rebellion, whats happening with russia. Weve seen kids reading poetry making speeches singing nationalist songs. And what they say, when you ask them is before this conflict began, we really didnt have a strong sense of being ukrainian. Now when there is a war in our part of the country, we are worried so much. So much emotion. And horrified for us. And im afraid that it can be returned to our country. Reporter since the conflict began last year there is this growing sense of nationalism and national pride. And this conflict is, in fact driving nationalism, both on the russian, prorussian side and as weve seen this morning, here now on the ukrainian side. Rupert with the teenagers there in mariupol. Now, relations between the uk and china have seem to have taken a significant leap forward after britains future king Prince William, met the chinese president , xi jinping, on the first visit to china by a member of the British Royal family in three decades. After meeting the president in beijing, the president has now arrived in shanghai to open the great festival marking the start of the year of cultural and Business Exchange between the uk and china. John is in shanghai for us. John, plenty of Photo Opportunities there, of course but is anything thorny being discussed while Prince William is there . Has he raised anything difficult with xi jinping . Reporter not certainly in front of the ears of the watching media, lucy. You wouldnt expect him to of course. And i think we can be pretty certain that those thorny issues will have been swept to one side. That meeting with xi jinping this morning from the british governments point of view that was all about delivering a warm message, trying to cement ties william delivering this formal invitation from the queen to president xi for a state visit later this year. And its being reported widely as an attempt, if youd like to build ties after a period of pretty frosty relations between beijing and london. The Prime Minister david camerons, meeting with the dalai lama a couple of years ago, hasnt gone down well in china. Questions about britains support for calls for greater democracy in hong kong havent gone down well in china either. But, of course the other focus of this visit is this trip to shanghai. The prince has arrived here now, opening this great festival of innovation, as theyre calling it, so its not just a dploeltic push, but its a big trade push as well selling brand britain to china. John thanks so much for that from shanghai. Prince william managing to slip in one comment, we understand on the illegal wildlife trade, which is something he cares very passionately about. Now, australians are well used to dealing with heat. Last year the country recorded its third warmest calendar year since National Records began over a century ago. But in one small town in the outback, theyve found an unusual way of coping with extreme temperatures as John Donnison reports. Reporter there are few places hotter than coober pedy. Temperatures in this outback town regularly exceed 50 degrees. And the extreme heat has led to a unique way of life. So welcome. Reporter thank you. Wow. People in coober pedy have gone underground. Bernadette roberts, like half the towns population lives in a dugout below the surface. And what sort of temperatures are you getting here in the height of summer outside . 50s, you know . You hear in the Southern States and Eastern States in about the 40s, we get the 50s. So thats a nice day. But once again, weve got our dugouts that we retreat into. Reporter and i guess for those living aboveground, its just the cost of keeping them cooler . The airconditioning. You would have to have your airconditioning 24 7. And that would be extremely expensive. Reporter and coober pedy people are well used to digging. Its a mining town. Each one of these piles, there are more than 2 million of them is where people have been mining for opals. All underneath coober pedy there is this incredible network of tunnels left by more than a century of opal mining. This town was built by miners. But whats unique here is that people chose not only to work underground, but to live here too. To escape the blistering heat of the outback. And its really noticeable. Its a good 10 to 15 degrees cooler down here than it is up above ground level. Reporter harry and annies home is cut into the rock face. Harry, a miner himself, says underground living was a natural way to go. I think it started because people were mining and when they mined, they thought, oh, its a lot cooler in there. Can we live in there . And a lot of them just lived in the mines, actually the shafts that theyd dug in sort of the hill. Reporter and for annie, there was no question of living aboveground. Because youre living in a dugout, that its nice and cool and everything and if you dont want to go outside, you dont. You hibernate. Reporter coober pedyans will emerge in a few months time. Australia has just experienced its hottest year on record. Global warming could see temperatures rise still further. Meaning dugout digs could be an idea that catches on.

In this half hour it may have fallen off the front pages, but the battle against ebola in west africa goes on. We report from liberia on the specialist teams, trying to track down the last two cases there. Well also take you live to sierra leone, which has seen 35 hurkz 3500 deaths from ebola. The local food Innovation Summit kicks off today. And the likes of lowcalorie antiaging chocolate and caloriecontrolled 3d food printing is stealing the line. But the underlying message is serious. Feeding the growing worlds population is a monumental challenge which means traditional products will have to become hightech. Welcome back to gmt. Lets turn our attention now to the ebola epidemic which has claimed thousands of lives in west africa. It was nearly a year since the World Health Organization first declared the outbreak in guinea. The disease quickly spread. It reached into neighboring sierra leone and liberia. So far 9,500 people have died from the virus in the three countries. The overall numbers of those infected stand at over 19,000. But, they have been falling. By the end of january this year confirmed cases fell to 100 in a week, for the First Time Since june last year. Infections have remained at this level since then. Aid agencies though, are warning that eliminating ebola for good is going to be a slow and difficult process. Well, in a moment were going to take you live to sierra leone. But first, lets take you now to liberia and the bbcs andrew hayden. Reporter this is the end game in liberia. A medical team hunting for the final traces of ebola. Could they be the last to suffer . Four caught the virus, three are dead. For the rest daily checkups. Theyre halfway through a 21day quarantine. Quarantine. It makes you to worry, it make you to you know, have fear. Youre counting the days now . We are, counting praying. Reporter dr. Masala is leading the last push to confirm the virus, and its working. No new cases confirmed for 11 days now. Reporter so this could be the last family . The last family but its the last family yeah. The last stretch, okay. So a lot of pressure on you to get this right. A lot of pressure, always. Reporter but then bad news. We race off to a nearby clinic. A sick woman has been found by one of the doctors team. Complaining of back pain joint pain was vomiting. Reporter once more shes one of their neighbors. It seems shes been hiding her illness. We have a case. As she rests, dr. Falllaah raises the alarm. Well its worrying news for you. Its another it should be very worrying. If it comes out positive. If it comes out positive its a new worry for us. It mean that yeah. Reporter more people to track down. Yeah. The civil right against ebola here was being waged like a military campaign but its changed now to into something more like detective work with people like dr. Fallah chasing down every last final lead and fighting against complacency. But later, dr. Fallah learns the woman tested negative for ebola. Its not the end of liberias struggle but hes getting closer. Andrew harding, bbc news monrovia. Lets take you now to sierra leone and join clive myrie, who is there for us. Clive, rather optimistic attitudes in liberia at the moment. Whats the situation on the ground where you are . Reporter you know theyre optimistic here as well but certain amount of frustration has because of a spike in the number of infections and transmissions. The trend, certainly since the beginning of the year has been down, and that has led to a lot of optimism. But a little bit of concern now, that some of the infection rates are beginning to go up. Im actually on board the British Auxiliary ship argas. Its been off the coast of west africa here for the last four to five months and the since were having a few problems with sound there, as you can imagine, being on a boat off the coast of west africa a little bit difficult with communications there and clive. But clive has also been on land in sierra leone. This is his report. Reporter we watch as a doctor tries to revive a young woman who suffered heavy blood loss after giving birth. But theres no pulse, as her head rests in her mothers lap. It seems nothing can be done to save her. Seconds later, its confirmed shes dead. Her name was amanata and she was 23 and shed given birth at home the night before. Outside, speaking to a matron and holding her newborn granddaughter, amanta says when her daughter fell hill they took her to a nearby clinic but they were turned away. There were no beds. This another tragic story in a land where ebola has cruelly exposed the shortcomings of a Health Care System that cant cope with everyday problems let alone a killer virus. A childs vaccination is a rite of passage, but in sierra leone, what should be routine is the sum laced with menace. This clinic has seen a 23 drop in vaccinations, because mothers are worried staff could pass on ebola. But the fear cuts both ways. Studios in freetown this afternoon. Reporter cecil is a pd are journalist who made his own news. His wife fell ill with traced of blood in her urine, but it wasnt ebola. She needed help. No one wanted to treat her, because they thought she may have ebola . Yeah. Yes. They couldnt actually touch her. They couldnt actually touch her. Reporter she went into a diabetic coma and died. But more than 200 medical staff have lost their lives to ebola, infected by patients they were treating. Its a Health Care System short of money, crippled by fear and unsure of itself that ebola has attacked. Years of chronic underinvestment means some Health Facilities dont have proper sanitation or even cleanrunning water. The hope is the Current Crisis will galvanize change. This dutchrun Lab Tests Blood samples for ebola in pregnant women in just six hours, much faster than usual, giving confidence to medical staff. This is the kind of Equipment Health care advocates say the government must invest in. Part of mitigating against any future level of impact that africa has had, means we must we must invest in health systems, and the time for investment is now. Reporter as amanatas body taken we the big question is will the daughter she left behind grow up in a land with a Health Care System that is finally fit for purpose. Clive myrie there in sierra leone. Lets try to return to clive now, who is on board hms argas off the coast of serer leone. Clive is there and will bring us reports throughout the day here on bbc news. I should tell you on tuesday, bbc africa is holding a special digital conference on ebola, and to kick things off, well be hosting a live facebook q a with david david, and dr. Bruise elwood the w. H. O. Special representative for ebola response. Hes been in so many press conferences, so his face im sure, is familiar to you. But what would you ask them if you could . Head to our Facebook Page now and post your questions for the live q a on tuesday. Thats at facebook. Com bbcworldnews. Time to catch up on the business. Aaron is with us now. Almost an upgrade on my mobile phone. Interested what youre going to bring me. Are you going to say what youre a typical user of. What do you think . Youre an apple. Im an apple. There are other phone devices and companies out there. Theres a new samsung . The jurys still out on that. Ill explain. Hello, lucy. There you go. Samsung say they have a new edge in their ongoing battle with apple. And this is it. Its actually called the galaxy s6 edge. Now, the phone has a threesided screen. Yeah, it does. A threesided screen and a whole host of new features including an upgraded camera also the ability to be charged wirelessly. The big question its a big one, is will it be enough for a company thats being kind of squeezed at the premium and budget ends of the market. Our tech guru now reports from barcelona on samsung and all the other big announcements at this years mobile world congress. Reporter its already putting powerful little computers in the hands of billions of people around the world. And in barcelona this week the mobile phone industry is trying to show jaded consumers its got something really different. The truth is that these days all mobile phones are pretty smart and most of them look pretty much the same. This is apples iphone this one is made by chinas huawei. And that makes it all the harder for the leading mobile phone makers to stand out from the crowd. Samsung knew it had to make a big noise this year. It may be number one, but profits are down and its under pressure from apple and cheaper chinese offerings. Here was its answer. These are the smartest phones in the world. Reporter but its this version with the curved edges that samsung hopes will win over its customers who felt some of its previous phones were a bit plasticy. The phone has apples irkiphone in its sights. We offer competition, because it offers consumers many different options. So for us looking a to the premium end of the durable glass, the color that youve never seen before in mobile phones before really i think, resonates with the consumers. Across town a fastgrowing rival was stepping up the competition. Huawei, unknown outside china a couple of years ago, is now a major smartphone server. The huawei watch. Reporter and here it unveiled its first smart watch. Chinese firms are now a real threat to the likes of samsung. If you rest on your laurels, other companies are willing to take the crown from you very quickly. And were starting to see that from the chinese with huawei here today, with xiaomi as well and theyre not really coming out with phones but with wearables and some of them are very desirable. Welcome to a new reality. Reporter htc, another firm struggling to make an impact with smartphones, was showing off a Virtual Reality headset, a video game. Staying ahead in the mobile industry means always being ready to change tact. Bbc news barcelona. Of course, well have more from barcelona over the next day or two. Okay here we go. Ive got some problems here. The next big thing. That is what every Innovative Company wants to come up but i tell you what when it comes to food is new and original as important as organic and simple . That is one of the many questions that the global food and technology Innovation Summit will look at over the next few days. So what foods could we see on our supermarket shelves in the coming years . Could it be what is it . Basel seed drink with honey. How about this . This is good. Antiaging chocolate. British scientists have created a 39calorie chocolate bar that will make you look up to 30 years younger we want some of that apparently, certain cocoa and a potent algae extract are the ingredients that become up these claims. Or what about meat without the guilt . The laboratorygrown beef burger is making strides towards tasting better and costing less to produce. Its not unrealistic to think that our meat could come from a lab and not a field too soon. Im not too sure about that. And furnt growing it in a lab, you could be printing it at home. Yes, in the future connections between your Wearable Health tech means that consumers could monitor exactly what calories they eat by deciding exactly what nutritional content go into their 3d printed food. Okay mike fairs is managing director and director of food Innovation Services and joins us. Mike, it all sounds very scifi but its great to have you with us. Hey, briefly, tell us what goes on at this gathering. Its only been going for about five years. What are they talking about . What goes on there . In short, the future of food. Its very important that as an industry, we look to where consumers are going to be thinking and what their needs are, as we go forward. So even some of the things youve mentioned there sound quite futuristic. But in five years, if you look forward to what consumers needs are around health and taste, well see some of these things becoming more mainstream. Okay. Well, look im holding a chinese product, its bubble tea, and it can travel around the world and you add your own water. Things like that. Is it about fun foods or the underlying message is pretty sure. Surely, this innovation has to do with or has to be a focus on sustaining or Sustainable Foods to feed the growing pls of mouths that weve got around the world. Yes youre absolutely right. Sustainability will be one of the key issues thats discussed. And you know if you look at where we are in the western world and what we consume and ask the question how sustainable is that, we will need to start looking at different sources of protein, so for example, insects is one example, is something that will be discussed. And although its elmmbryonic at this stage, there are 2 Million People that already eat insects. Well see that come into nuggets and cheese but theyll be made from something else. I grew up in australia. I had plenty of flies fly in my mouth by accident. Very tasty, indeed. Let me ask you this. Another big focus that we do a lot on this program is food wastage. In fact, last week we had another report out that highlighted Something Like a third of the worlds food in both developed and developing world is wasted. Is innovation looking at ways you know labeling packaging, i dont know that we can sort of reduce that number . Very much so. And its a frigening number when you look at that in tons. But there are technologies that are coming now into the forefront, to name one, theres a technology called High Pressure processing which actually extends the shelf life of foods, without cooking it. So you can get the same nutritional content, the same raw flavors and taste, but with an extended shelf life or created naturally through pressure. So the technology will play an important part in making some of the foods we currently consider to be short shelf life and give them an extended shelf life. There is also actually quite interestingly a number of popup restaurants opening up where theyre taking the food that can no longer be sold from farmers markets and theyre making this into restaurant menus for people to come along and try it. So the need is already there from a consumer point of view. Ugly fruit, ugly vegetables, lets stop plowing them back into the fields lets eat them. They taste the same. And you mentioned a few times, the word shelf, i want to ask you, give us an idea. For the viewers around the world watching this what do you think, rattle off some of the innovative food stuff that we may be seeing on our shelves in two, three, five years time. Sure. Weve already talked about insects. So that will definitely happen. That will come. And already has started. But take Something Like seaweed, a plentiful source around the world, its nutritionally very good for you, and because of where it comes from, it also has a great ability to season our food. We still want food that tastes great. But using seaweed and dried sea wood as a way of creating something natural and perhaps consuming less salt. Because health is such an important factor for us we see a lot of highprotein foods coming in, so whey proteins proteins that are grown from substrates and labs and so on and thats a little farther off, but certainly insects and some of the peruvian star cuisine might be an attraction well see some very unusual and different fruit and vegetables coming through too, that i have very good Nutritional Properties that we can still enjoy, but will give us a bit of a benefit and a bit of a kick from a health point of view. And mark you know people may think we rehearsed that, and you cant sea me but im holding in my hand a bag of dried seaweed. Thank you very much. Appreciate your time. Follow me on twitter, tweet me ill tweet you back. You can get me bbcaaron. Youve got to try this. I quite like seaweed. Do stay with us here on bbc world news. Still to come the hills are alive with the sound of music. Its aarons favorite movie. On the 50th anniversary of one of the worlds most popular musical musicals, is of course the sound of music and were looking back on the making of the movie. Of course you dont want to have worked on a film that is a flop. But we were very doubtful of the outcome. We were wrong. You can call me shallow. But, i have a wandering eye. I mean, come on.

The top stories this hour iraqi forces lost a military operation to recapture saddam husseins hometown of tikrit from Islamic State fighters. The latest we have one of the commanders of the ukrainian revolutionary guard forces involved in leading the operation and Islamic State is using human shields. A u. N. Report has highlighted the devastation and continuing loss of life in eastern ukraine. The report says at least 6,000 people have been killed in the conflict so far. Finally on gmt today, it is truly one of my favorite films. The sound of music, which was released 50 years ago, it became one of the most successful films of all time. It is the story, of course of the novice nun, maria, who captures the hearts of the von trapp family with her songs. It was shot in the austrian town of salsberg. Bethany bell has been to meet gael who worked as an assistant director on the film. The hills are alive with the sound of music reporter 50 years on the sound of music still enchants its fans and its immortalized salzberg in the austrian alps. Gael worked on the movie as an strant director. I met him at the site of the von trapp garden in the film. He told me that the rowing boat scene in which Julie Andrews and the children fall into the water almost ended in tragedy. One of the exciting scenes i worked on here is when the boat tipped over. We had arranged that Julie Andrews would step out of the boat that was tipping forward, grabbing the child, and saving little gretel. Unfortunately, Julie Andrews went overboard backwards and the child in the other direction, went down under right away. In the film you have an immediate cut and in the next seconds, there were a lot of people in the water trying to save the little girl. Poor gretel. It was a bad experience for the child. Reporter gaels job was to direct the local austrian extras. But there was a problem, because they didnt know the songs. Not even edelweiss. Well, i was asked to instruct the crowd to join in singing that song. And i had to tell them that we first have to teach them the song. He was very surprised and said it was an austrian tune it was the National Anthem . No it was not, it was rodgers and hammerstein. He says the movie is still a bit kitsch and too austrian for american tastes. We thought it would not be a success. Of course, you dont want to have worked on a film that was a flop. But we were very doubtful about the jut come. We were wrong. Reporter the sound of music is still not one of austrias favorite things but after 50 years, people are becoming reconciled to the film, which brings so many tourists here every year. Who knows, maybe one day, theyll even learn the songs. Bethany bell bbc news, salzberg. Im such a fan, ive been on the sound of music tour in salzberg. Thats all if gmt today. You a fan, yellda .
