Listening to the news room from the b.b.c. World Service with meaning Miles the leader of the Islamic state group Abu Bakar a Baghdadi is both a feared and towers manic figure beaded and wearing a black turban he came to the world's attention when he preached in most always great mosque a month after yes a take in the city and 2014 now the Russian authorities say they're investigating whether one of their airstrikes has killed him Alan Johnston is our affairs editor and he's here Alan So what more details are the Russians giving We've heard a statement from the Defense Ministry in Moscow and it says the Russians got word of a major gathering of militants in the southern outskirts of the Syrian city of Raca and their warplanes targeted this gathering in a devastating 10 minute nighttime raid they say that they killed more than $300.00 militants in these airstrikes including senior figures and the Russians say they're checking information that among the dead was the leader of the Islamic state group a back Baghdadi now we have to treat this with some considerable caution I think we have had reports of this man's death before which of course proved not to be the case and it seems that the Russians themselves are less than certain level of the foreign minister has just come out and said that they are not 100 percent certain that they've killed back a Baghdadi the u.s. Led coalition which is also engaged in the fight against Dias has also said that they can't confirm his death and one point I would make is that this raid went on on the 28th of May that any 3 weeks ago and now something as momentous as the death of Baghdadi had indeed occurred we might expect to heard something about it before now I think and the question also is if he has indeed been killed would it matter that much for ah yes I mean he hasn't been heard of he's not made any. Public statement since last November does it really matter particularly with I is in retreat now about that he really is the central figure in the story of the Islamic state group as he said when they founded their caliphate it was al Baghdadi himself in his dark clerical robes who made the founding statement he immediately became the face of the movement the world's most wanted man if he was killed it would undoubtedly be a major blow for the organization a further sign the ins is being dismantled that is losing territory that it's being hunted and harried and has been penetrated by enemy intelligence agents so thoroughly that it is impossible to protect its most valuable individuals Thanks out on a Johnston. There are 2 dominant emotions in London after this week's tower block fire sorrow and anger emergency services say they may never be able to identify all the victims of Wednesday's tragedy they're spending a 3rd day searching the building for remains the anger meanwhile is being directed at all levels of government the newsroom's dot com Savidge has been monitoring developments for us 1st of all Jonathan this painstaking search is continuing What's the latest from the scene Well the 1st thing to see is in the last few minutes the b.b.c. Can say that we understand that up to 76 people may be missing and that includes the 17 people that the police have confirmed has died the Police though say that the number will be significantly higher than that they are preparing us for that what we see is the hope it won't reach 3 figures and that lack of clarity speaks to the immense difficulty involved in the search and recovery operation some parts of the building are too dangerous for firefighters to search through in fact the Fire Service says a good half has yet to be searched in detail so they're using dogs and drones to search the upper floors at the moment and such was the intensity and the effect of the fire that as you see it may be impossible to identify everyone who died so that means continuing trauma and uncertainty for people who haven't seen or heard from relatives many of course have already lost homes and possessions Meanwhile a lot of anger as I said what are going to be the political ramifications of all this the prime minister tourism a visited the area said that she was criticized for not even speaking to any of the victims wasn't she how much pressure is she and other politicians under will inevitably with state owned housing such as Grant felt her or any decisions that are made that could have exacerbated this will come under enormous truth and for example there was news to bring clerks system in the tower in fact the local councillor has told the b.b.c. That it was discussed there was thought that to install one would have delayed and made the refer Bushman of the block more disruptive that refers prefer Richmond included aluminum panels being used to clog the building. That experts say that a more fire resistant type could have been used at very little extra cost now you say yesterday to reserve May the prime minister visited the site she met with members of the emergency services but no residents so there was no opportunity for them to express the growing anger at the national government we can see that through the me is no visiting injured people in hospital today and we can add in the last few minutes it's worth mentioning that the queen and that you Cambridge have arrived at a rest center they're also going down there today another government minister Sajid Javid he is promising urgent action people don't want to wait months and years for some report and that's exactly why I'm saying this emergency review of similar buildings is starting now it's going to happen right away but what's going to inform that is the 1st results from the fire investigation report there's already a police investigation going on the fire investigation is going on alongside that but we do need to listen to the fine Vesta gaiters and they tell us and everyone who is concerned about this exactly what needs to be done so yes there are a number of immediate investigations and reviews taking place in the long term the Government's announced a fool scale public inquiry which will be led by a judge but right now if you live in a similar tower block the sooner there are any answers at all the better you know lots of concerns that Jonathan thanks very much later today the u.s. President Donald Trump is expected to announce his administration's harder line towards Cuba it's no surprise that he's chosen a visit to Miami to retighten the rules on trade and travel there Miami is home to hundreds of thousands of Cuban Americans who fled the island they'll be happy that President Trump is on doing part of President Obama's policy of detente with keeper but how is it being viewed in Havana our correspondent Will Grant reports. For 2 and a half years the Americans have been invading Cuber again by air and by sea hundreds of thousands of u.s. Citizens have come to see this once for. Big Niland for themselves some arrived on the 1st cruise ships to cross the Florida Straits in decades others on newly reinstated direct commercial flights on low cost airlines all of them benefiting from Barack Obama's relaxation of strict travel rules the President Trump may be about to tighten them again Jack Greeley brings students from the business school of western New England university to have Vanna to study the Cuban economy it just seems like so what of populations with. You know there's a great deal of the food between the 2 countries socially so I think a lot of people you know would would say that is concerned that. But it's not just educational visitors that might find it harder to operate. Cathing is a small privately owned coffee shop in Havana's own town it is always bustling its brunch rivals anything in New York or London it's coffees and fruit juices some of the best in the city Nelson the world leaders started l. Cafe a little over a year ago and has seen his business grow rapidly and made to boost tourism boom now he fears President Trump may undo all that hard work in this mall main way Cuba and United to stay there to build ever laging less adjustable aging that's had to be level aging and maybe the fishing can be a very good relationship between Cuba and United States. And this in the beginning is not fair changing the law while small businesses in Cuba are concerned especially those involved in tourism it is big business that may stand out to lose on breaking into the island's emerging economy President Trump may ban u.s. Firms from working with the commercial wing of the Cuban military the trouble is says Cuban economist recount of the order is given the military a present in every sector of the economy that is simply not realistic how. I want to work in Q I want to invest in Q I want to do business and I wore the Polish sector in Q one it's impossible but if you want to do business in Cuba and you want to be serious about doing business in q. What you got on board the public sector. And cafés bracing itself for another lunchtime rush but there are also bracing themselves for Donald Trump It is expected to tell a rollback on the policy of engagement will be couched in terms of Cuba's poor human rights record however even Human Rights Watch and Amnesty International have said that a change in policy won't help with that issue ordinary Cubans and Cuban Americans are just waiting to see how far Mr Trump will on one of his predecessors biggest foreign policy achievement that was Will Grant reporting from Havana You're listening to the b.b.c. World Service Still to come on the news from have Chinese scientists made it more possible for us to teleport ourselves yeah seriously Stay right there and we'll find out the answer 1st islands here with the headlines the Russian defense ministry says it's checking reports that the leader of the Islamic state group Abu Bakar daddy may have been killed in a Russian air strike in Syria last month Queen Elizabeth is visiting the area of London where a fire destroyed an apartment block on Wednesday and a family row as erupted over the will of Lee Kuan Yew the man who led Singapore for more than 3 decades yes members of Mr Hughes immediate family are disputing the will in part because they can't agree whether Mr you wanted the house he lived in demolished after he died joining us in the studio is our Asia Pacific editor Michael Bristow Michael it seems like a very bizarre family fight what's behind all this well lots of legal arguments there very complex this one is no different but essentially centers on 2 main things one of the things you just mentioned there the house that Lee Kuan Yew lived in before he died 2 years ago in his final will leak when you said he wanted that house demolished he didn't. Wanted to become a shrine to everything needed Cheve in Singapore pretty soon the Shenlong who's the current prime minister of Singapore says he has grave concerns about the circumstances of the drafting of that will and whether or not Lee Kuan Yew his father knew that this clause to demolish the house had been inserted into the will so that's the 1st thing the 2nd thing is about money in the penultimate will there were 7. Will and he left more money to his daughter $2.00 sons one daughter and in the final will the money was left equally liquid and long the Singapore Prime Minister is also question the circumstances surrounding that change in the will so very complex argument what do you think ordinary Singaporeans are making of all this looking on in horror well in say a century Yes they are because it's of private family matter but it's been played out in public all the main participants have been put in information about their points of view and documentation on Facebook so it's there for everybody to read everybody to get involved in is important because you've got to remember Lekan use one of the great figures of East Asia after the 2nd World War He turned Singapore into this bustling more. Rich city state that he is today his son is currently the prime minister so it's not just a private it's about the people who lead the country and in fact one of the new son the one who is not the prime minister said he fears that his brother the prime minister might use your guns of state to decide like air pushes in his particular direction so it's a put private family debate turned into a public row it's over Michael thanks very much indeed. British security officials have told the b.b.c. They believe North Korean hackers were behind the global cyber attack last month the attack affected governments hospitals and major companies with Mao web demanding money in return for access to documents. Gordon Corera is our security correspondent Bakit Berry as you remember thousands of people were locked out of their computers by something called ransomware receiving an a note telling them that after pay to unlock their data and hearing that Britain the n.h.s. Was particularly badly affected now Britain's National Cybersecurity Center began an international investigation and in recent weeks it completed its own assessment which I'm told believes the attack was launched by hackers based in North Korea specifically a group known as the last or risk group now that kind of assessment comes from not just looking at things like similarities in computer code the kind of thing that private sector research is of also noticed but it's also likely to be based on the kind of capabilities the National Cybersecurity Center has as part of g c h Q Although the at the intelligence or the material that leads to that assessment won't necessarily be made public so it's the strongest indication we've had that the attack did originate in North Korea people are careful to say though that's not quite the same as being able to prove that it was the North Korean state which gave the final order and it's also worth saying the hackers didn't target the u.k. Or the n.h.s. Specifically rather they blasted out this malicious software to see where it would land Gordon Corera it's nearly a year since Britain voted to leave the European Union and now with negotiations about to begin a senior member of the royal family has made a rare intervention in the debate over how Bracks it might work Queen Elizabeth 2nd son Prince Andrew the Duke of York was the u.k. Special representative for trade and investment for 10 years until 2011 he's been attending a Commonwealth Science conference in Singapore where he spoke to our business correspondent so Ranjit Lael the Duke of York said he was as much in the dark as anyone else about Brecht's it he said there was going to be uncertainty and Upheaval in the u.k. Over the next several years while it plays out but that leaving the e.u. Would bring new opportunities in markets beyond Europe such as China in my experience recently businesses that look over the garden fence of gone. Grass is not quite as dark and. Unforgiving as you might expect I'm actually going to have the fence I'm up for some fresh grass it's highly unusual for members of the royal family to comment publicly on contentious political issues and Prince Andrew is the 1st to share his thoughts on breaks it the prince said he was optimistic about the new opportunities which are now open to Britain little islands here with some more stories from our news desk Chinese police say an explosion at the gates of a kindergarten that killed 8 people and injured more than 50 was caused by a 22 year old man who died in the blast police in the eastern province of Jiang Su have identified the attacker as a man named Shu officials say they searched his apartment and found bomb making materials John Sudworth reports from Beijing the 22 year old man made the bomb in his rented room near the kindergarten in funk County in eastern China according to the police he detonated it shortly before classes were due to be dismissed killing and injuring parents and children waiting at the school gates photographs from the scene show people lying on the ground some bleeding heavily a public security ministry statement describes the man as having health problems and state run media is reporting that along with bomb making materials the police found the words death and extermination scrawled on the wall of his home Spain and Italy have warned that euro group finance ministers will veto the latest Greek bailout unless Greece drops charges against 3 employees of the Greek privatization agency who have been blamed for losses speaking in Athens the Spanish economy minister Luis de Guindos said Greece would not get the promised 8500000000 euros until the situation was resolved the Greek government has agreed to grant immunity to 3 employees from Spain Italy and Slovakia but a judge has not yet dropped the case and thousands of events are being planned across Britain over the weekend to mark the. 1st anniversary of the murder of the Member of Parliament Jo Cox She was shot and stabbed to death by a far right fanatic as she campaigned for Britain to remain in the European Union Her father Gordon Leadbetter said the commemorations would be a celebration of the principles she stood for thanks Eileen we've got some potential exciting science news now both for practical scientists and for fans of science fiction as well it's all about photons all you need to know if you don't already is that they're the smallest units that light can be broken down into now Chinese scientists have successfully transmitted in Tangled photons between space and but why are they in Tangled Justin Webb asked the science writer Brian clay it's the way they created in the 1st place the kind of treated as twins in a way that they almost become 2 parts of the same thing and no matter how far you separate them they are still connected so if you look at one it effectively influences the other one what are the Chinese done now. They have this satellite it's about 500 kilometers up and it's broadcasting down to the earth the trouble is these quantum entangled particles it's very easy for them to lose the entanglement and when we send them to say through a fiber optic cable the can only go about 100 kilometers but what the satellite can do because it's broadcasting mostly through empty space is it can send the much further so it's enabling them to connect stations about 1200 kilometers apart so it means you can start looking at a kind of quantum Internet where you can send information totally securely over long distances brings up teleportation and all sorts of kind of the things that might become possible presumably if the Chinese if this experiment results in further experiments and further success it might find this quantum entanglement is used exactly as you say in teleportation inside quantum computers which are just starting to be developed we're talking about something that maybe is 1020 years old which would be far more powerful than any computers we have today and it absolutely relies on the fact that you can teleport a quantum particles in one place to another using this technique so that's been done already or about teleporting yourself. That thankfully in a way is very unlikely to happen because basically you've got to do it one particle at a time and there are so many in your body it would little e take millions of years no never no these things get speeded up very suddenly and in those there are all sorts of laws about computers I mean you but basically this is it if it were to happen I mean you could do it would you still exist in the in the place that you previously existed in what would happen to that's the downside of using it for transporting people basically what it does is makes a perfect copy and destroys the original mind boggling stuff from Brian Clegg a science writer whether it's a bare breasted statue of a Hindu temple or paintings of prostitutes by Toulouse to trek art has rarely shirked away from Iraq to save them and love now curators at the British Museum in Londo
