And now, bbc world news erica 6789s this is bbc world news america. Reporting from washington im katty kay. The white house is in talks with russia to restart a ceasefire in syria but its small comfort to people still hammered by attacks. The small flow of migrants from turkey to greece has stopped but some are now stuck on the island of lesbos. And taking a test drive on the red planet . Simulating what it would be ike to explore mars. Welcome to our viewers around the globe. A as Syrian Government airplanes continue to bottom bomb rebel areas the white house says today its talking to russia to try to get the ceasefire working again. Over the past week the city of aleap has seen a string of deadly bombings including one on a hospital that killed at least 50 people. Today a mosque was among the targets. Richard galvin has more. For seven days now the people of aleppo have come under relentless bomb bored ment, shatering the socalled ceasefire. Government forces have been carrying out air strikes in rebelheld areas and the rebels have been retaliating. With 200 people reported to have been killed in aleppo this week, World Leaders including the u. N. Secretarygeneral bankyman have been holding crisis talks to try to save the ceasefire. We hope and im urging again the parties to refrain from such violence. There has been fighting enough. Six years. But so far in aleppo the fighting continues. This reported to be the aftermath of more air strikes by government war planes earlier today. And following the destruction of this hospital on wednesday night there are now claims that another medical facility has been hit. The population of syria is absolutely exhausted after five years, so its all so vulnerable now and if the fighting continues like it is now, im very worried that we will have a catastrophe beyond belief. In many areas in syria. Some in this beleaguered city believe the renewed bombardment may herald the beginning of a new offensive by government forced to regain full control of alepo, a sense likely to be bolstered by the Syrian Military excluding the excluding aleppo from areas for a brief period of calm. It looks grim. More on the pickup in fighting in aleppo. I spoke with the dean of the Johns Hopkins school of international studies. This ceasefire was meant to be the bright spot in syria an its lasted, what, two months . Do you think there is any chance it will be revived . I dont think so. I think the ceasefire was really treat bid both sides as an opportunity to rearm themselves. It was really a pause rather than a ceasefire. It was treated as a cessationve hostilities so it didnt have the legal ramification of a ceasefire so i think the two sides have armed exactly to have another go at fully capturing aleppo, which is the big prize in syria in terms of positioning one or the other side in the drivers seat if and when there is a final conversation about the futd of syria the when you look at those pictures, miserable pictures out of alegal aleppo and you look at the hospital hit today, a mosque that was hit, it doesnt look like the rebels are managing to put up much of a fight, does it . Well, absolutely the government does have the upper hand but the rebels are also shelling government positions. Worst thing about what were seeing that it seems like the carnage has reached a new level. There is a new level of tolerance i think on the part of the governmentorces in particular about, you know, what theyre willing to do in order to take aleppo. This is a drive in order to really be able to create a corridor that runs from damascus to latakia which puts the government in a very strong position in terms of dictating 9 end game in syria. Finally, the russians are clearly in a very strongs position in syria. The russians and the white house said theyre polede holding talks. Secretary of state john kerry spoke to minister lavrov today. Do you think the us russians are now fully on board with resuming military activities in syria . Well, the russians would be interested in a ceasefire if there is sufficient International Pressure on them because of the humanitarian consequences of the bombing but ultimately i think they are following what is the strategy of the necessity of control of aleppo by the assad government. Anything lets anything less, theyre not likely to support a ceasefire. The decision to resume the war at this point in time is a deliberate decision which means there is a strategy behind it. I think that strategy to break the back of the resistance in aleppo and to once and far for all, at whatever humanitarian cost, put aleppo in the hands ever the assad government. And then i think they will be ready to talk bay ceasefire. In thanks so much for coming in. Well, the unrest in syria and other places is helping to fuel the crisis of refugees fleeing to reach europe. But a deal last month has stopped the flood. The number of mike rants taking the dangerous sea crossing from turker turkey to greece has fallen dramatically. Last month 5,000 were landing on lezzbos every day. Lesbos every day. Today there were none. When hope turns to fear it sounds like this [screaming] a migrant boat bound for greece, men, women, children on board, intercepted by the Turkish Coast guard. Look now the man in black pulls a knife. Resistance gone, the boat is towed to shore. This ute route is all but closed. A potent symbol of the e. U. Turkey deal. That crackdown on smugglers and rumors of poor conditions mean migrants dont make the journey. The first greek face many a fisherman by trade, for months it was people he pulled from the water. Saving so many lives, greece has put him forward for a nobel peace prize. I have seen many people drown. I even got angry, asking myself, was there something more i could have done . I get frustrated seeing those people being the victims when it wasnt even their fault. Beaches once choked with new arrivals are quiet. In less than 18 months more than half a Million People arrived on these shores from turkey. Moat of their life jackets and boats have been cleared away and the majority of migrants have headed on into theiron union the European Union but thousands are still stranded here, unable to get to the mainland and fearful of being sent back to where they came from. Detained and angry, frustration boils over. This week, police fired tear gas at young men throwing tones. Moria is a place of waiting, of uncertain futures, and not always of safety. In here, its difficult. I felt here for my life you feared for your life in this camp . Yeah, you are right. Heading back out to the fishing grounds, these are calmer times for islanders. But theres fear, too, those fleeing fear and poverty may need their help again. Angus crawford, bbc news, lesbos. The u. S. Military has announced it will take disciplinary action against 16 Service Members in a deadly air strike in afghanistan lost october which destroyed a hospital and left 42 people dead. But the investigation concluded it was a tragedy tragic mistake and not a war crime, which means those responsible will not face criminal charges. That has angered the families of the victims and doctors without borders, which ran the hospital. Whag is the white house saying about this . Well, theyve had quite a lengthy probe and catalogued a complete storm of errors which theyve made purks everything from human error to technical error to equipment failure, violation of procedure, violation of rules of engagent. But they say the air crew and ground staff believed the whole thyme they were hitting a taliban command center, they did not intend to target the hospital, therefore it was not a war crime. They have disciplined 16 of their own, including officers. Not criminal charges but it can affect their military careers. Theyve taken steps to improve the operations in afghanistan to rebuild the m. S. F. Hospital so from their point of view theyve taken appropriate action. Doctors without borders meantime is saying this is not nearly enough, the attack went on for nearly and an hour and they want an independent investigation. What more do they want . They issued 12 questions to the military. They said the punishment is not proportionate to the magnitude of the death and destruction but they have acknowledged the militarys efforts and noted that hospitals get attacked on front lines and it isnt always investigated. But this isnt enough. They say this is not about rules of engagement but about humanitarian law. They say that intention cannot be the only criteria to determine if a crime was committed, especially when the you have multinational coalitions with different armies and rules of engagement. They havent talked about criteria but maybe gross negligence. Theyre asking still for an independent international investigation. Thank you very much. A sixstoifer building has collapsed in the kenyan capitol of nairobi after heavy rains and flooding. The red cross says three children and an difficult are being terre hauted treated for injuries. Nairobis police chief said traffic jams caused by flooded roads delayed rescue teams as they rushed to the scene. U. S. Authorities have confirmed the countrys first death linked to the mosquitoborne virs, zika. The 70yearolds blood did not clot properly. The u. S. Has recorded more than 600 zika cases in puerto rico. North korea has sentenced a man to 10 years hard labor after he confessed to spying and spreading religion in north korea. Hes the second north american sentenced for spying this year. I spoke a short time ago with the former Deputy Division chief for korea at the c. I. A. Why are things picking up in terms of this incidence of North Koreans tarking americans prisoner . What is the north trying get . It does seem to be cyclical, whether its a reaction to rising tensions or simply a decision by the Security Services to send a message. We have had, as you point out, the two citizens sentenced to 10 and 15 years of hard labor this year. We of course hope we can get them out but they probably will be in captivity for some time. In the past it has taken a highprofile american visitor to get them out. Is that what you expect this time . Not in all cases. They have at times been released to a lower of level official or sometimes just to themselves it. Seems impossible to predict with each cause what it will take. What is the treatment of these prisoners as far as we know while in captivity . It can vary. In the past it seemed there was stronger punishment for koreanamerican captives as well as those convicted of spreading religion. They were seen as a greater threat to the regime. Sometimes theyre kept in a guest house, other times forced to do hard labor the weve had a few weeks of u. S. Military exercises. That does seem to be the period when tensioned spike on the korean peninsula. How bad are the military tensions . Do you expect that once these drills are over, i think its this weekend, that could diminish a bit, help the situations . As you point out, the tensions tend to rise curing these during these annual exercises but also during the Korean Military tests and long range missile tests earlier this year. That usually causes the very strong north korean reaction. Weve had this rapidfire nuclear test and expect another probably before next Fridays Party congress, the first in 36 years. Its hard to know exactly of course what is going on inside north coreau korea by but i have read that the North Koreans dont like these in part because it forces them to spend money doing their own drills. Plausible in is plausible . Thats possible but they try to use them as an use for their own provocations and just to raise tensions in order to try to push objectives such as obtaining a peace treaty or trying to divide the u. S. From its south korean ally. Ok, thank you so much for coming in. Thank you. You are watching bbc world news america. Still to come on the program, as African Leaders work to save the elephants, were in namibia. 13 people have been killed fter a helicopter crashed in norway on the way back from an oil platform. It went down on an island west of bergen. Racing to the scene, but in vain. The helicopter was completely destroyed. Data shows it fell more than 2,000 feet in just 10 seconds. Giving everyone on board little chance. Witnesses couldnt believe what they were seeing. My wife and i were in the kitchen. It was around noon and we heard a loud bang. First we thought a boat or ship had crashed into the shore so i turned around. And i saw a huge plume of smoke and then it caught fire. 30 seconds later the whole shore was ablaze. Parts were scattered across land and sea. He you may just be able to see the news unfold, get the top stories from around the globe and clicktoplay video reports the wreckage on this beach. The last norwegian crash was 20 years ago. What might have brought this aircraft down . The same type of helicopter, an e. Crervings 225, has had problems before and has the was effectively grounded after ditching twice in the north sea with depear box problems though no one was killed. One expert says it may not be relevant glofmente the investigators will go in with very open minds. They they want to understand what happened in this case with no preconceptions. Of course they will be looking at the history but their aim will be what went on in this very specific case. Tonight its emerged that the crashed helicopter had a Maintenance Service delayed twice. Step one for investigators will be to find the black box if it survived this. Helicopters carry a million british oil and gas workers every year and the pressure is on for quick answers. For months weve been reporting on the threat to africas elephants and ryan rhinos. Century the population has fallen by 90 and experts say they could soon be exteekt. But in namibbier theyre reversing that trend. Tourist travel the world to see them but at the rate theyre current hi being killed this, kind of spectacle could be gone in our lifetime. Here in namibia, there say different approach to saving the elephants. Hunting. Few tourists come to this part of the country, so trophy hunting is the main source of income. Poachers have actually turned game keepers. This group has a license to kill a buffalo in this conservancy. A parcel of land managed by the community where animals can loan roam in and out of the unfenced National Park next door. There is a quota. Only a certain number of ape animal with shot each year, with the meat going to the community and hunters often pay tens tens of thousands of pounds. Most goes back to the people. People punt huntb to take the animals its going to die in a few years anyway. Why not . Wild animals are like anything. Its like cattle. You cant go on a farm and just keep Breeding Cattle because you are going to have too much eventually because there is not going to be enough grazing for it. Exactly the same with the game. People can get very emotional about hunting, whether for buffalo, elephants or lions but the fact is tourism in this area doesnt bring in enough money and hunting does. The hunters have to pay whether they find a bullo to kill or not and these are inside the park. They can look but they cant shoot. So when we saw it, we have to record it in the event book. The local community manages the conservancy, recording which animals pass through to help work work out the quotas. The money pays for the rangers or to bring electricity to the villages and it works if there is no corruption. All the if the hunting stops, then all the money we are getting from the hunting will stop also. O people will not take their children to school, theyll be unemployed also and some may return to being poachers as well. Its about giving these animals a real value to the people whose crops they destroy and whose children they they sometimes kill, not just something for westerners to come look at. In some places it might be enough to keep them alive. In others it wont be and there are less than a half million left p in the whole of africa. Need to find creative ways to save elephants and do it soon. Now, sending a person to mars is still years away, of course but britains tim peake has just taken another small step in the name of space exploration. Hes on the International Space station and from there has been controlling a mockup of an explorer on the red plan eat planet thats built in england. On earth a little piece of mars, used to test out a rover soon to be sent to mars. Tim peakes mission is to take it into that cave and look for areas of scientific interest. Tim guides the rover into the cave flawlessly. Next he has to find his target. On the top right we see the view through the rovers camera. This is what tim sees. The luminous rock is what he is looking for. He searches for 90 minutes for more targets. At the end, how does he do . Tim did a great job. It was a fantastic success. He did everything he needed to do. Drove into the cave, found his targets and got back out again. Thats all we needed. The team here believe humans could be orbiting mars in 15 years time and it will be much easier for astronauts to control robots from martian orbit than from earth. The distance can be as much as 250 million miles and it takes a radio signal 20 minutes to cover that distan. But its less than a second for an astronaut in orbit around the red planetting, making navigating the rober on the surface much easier. Its not possible to land astronauts on mars because a powerful rocket would be needed to bring them back. The challenge of actually landing a big space craft on mars, big enough to carry humans, we havent solved yet, its true. We expect we go there perhaps into orbit first and put smaller robots down to do the science for us and actually understand the environment better so we can build a space craft to take the humans down. For tim its been a successful day and another small step on our journey to other worlds. Thank you very mu. It was very great driving. Tim peak had an awfully long way to play with the roe moat control car. Looks fun though thats all for today. If you would like to find reap me or the bbc team, were on twitter.

Miss rosa its the pbs kids field trip. Can you guess where were going today . Heres a clue. So did you guess where we are today . Yes, at a bakery, where they make cookies and cakes and bread fresh every day, and guess what . Anwar here is gonna show us how to make whole wheat bread. Hi, kids. Im the baker here. Come on back. Lets go. Ok. To make the bread, first, we have to make the dough. So we mix things together, like water, yeast, flour, and salt. And then we really work with the dough like this, and its called kneading. After it rises, it goes in the oven. So then what happens . And then we have bread. Miss rosa wow, you never know what youll learn when you explore new places and new things
