hello. president trump has commuted the prison sentence for his friend and advisor roger stone. mr stone had been due to start a three year and four month prison sentence for lying under oath during the investigation into russian interference in the 2016 us election. the white house said mr stone would have been at serious risk of covid—19 in jail. within the past hour, mr stone has been speaking to the media. here's some of what he had to say. iam going i am going to do three things, i will write a book, another book, about the experience, because people need to understand the extraordinary abuses of justice in understand the extraordinary abuses ofjustice in our justice system. i will help

general flynn to get exoneration, because the refusal of thejudge to exoneration, because the refusal of the judge to dismiss is quaycentre drag it through the summer is outrageous, and i am going to do everything i possibly can on an independent basis to get the president re—elected, which i think is crucial. a short time ago, our north america correspondent david willis gave this update. well, roger stone, james, is a political operative, someone who has almost rejoiced in the reputation as a dirty trickster. now, he hinted during the 2016 presidential campaign that he was in touch, through an intermediary, with the wikileaks founder julian assange, and boasted that he was knowledgeable about the release to wikileaks of thousands of e—mails hacked from the server of the democratic national committee. he was sentenced to more than three years in jail and had been due to report to prison in georgia before next tuesday.

well, now he won't be going to jail at all — his longtime friend president trump has intervened, as, indeed, he had promised to do, or certainly hinted at doing, for many weeks. the white house, for its part, has said that this was an "overzealous prosecution," and that the prosecutors in the case had been pursuing a case that "should never have existed". one traces this back, james, to the antipathy that president trump has displayed to special counsel robert mueller‘s investigations into allegations of interference with russia before the 2016 presidential election. the president has consistently called that whole enquiry a hoax and he has sought to clear the name of the people who were surrounding him and were subsequently convicted because of that enquiry. they include, as well as roger

stone, former national security adviser michael flynn, and trump campaign manager paul manafort, who is currently serving time in prison. so this very much a sign of donald trump essentially, basically, looking to erase the memory, if you like, of that whole mueller investigation. is the president's power to commute absolute? absolutely it is in the sense that he can now effectively clear the record as far as roger stone, he won't be going to prison. and, indeed, this president has proved he is quite keen to commute sentences — he did so with the former illinois governor rod blagojevich earlier in the year, ditto the former new york police chief bernard kerik, so president trump is not a man who is afraid to use those powers, and he has done so again with his longtime friend

roger stone, here. david willis, there. and staying with the us, which is seeing a record number of new coronavirus cases this week, with more than 63,000 infections recorded on thursday alone. this comes two months after some states began reopening their economies, without having met the federal guidelines on how to do so safely. in the sun belt, in arizona, new coronavirus cases and hospitalizations are soaring, as sophie long reports. dance music plays. when the governor of arizona lifted the state's stay—at—home order, people partied, pre—pandemic style. it was a joke to us. we were just like, "yeah, covid's fake news." days later, many woke up to what will probably be the worst hangover of their lives. never imagined in my life i'd be in a hospital, you know, on a breathing, oxygen tube. and i felt like i was going to die. the bars and nightclubs have now been shut down again. the pumping music replaced

by an eerie silence. but the damage has been done. at the beginning of the pandemic, some hoped the summer heat might help slow the infection rate. well, if you want proof that that is not happening, it's here. it's currently around 44 celsius in phoenix. the temperature is rising, and so are the number of confirmed covid cases — at an alarming rate. arizona is now the coronavirus hot spot, not just for the united states, but the world. and yet people here are still queueing many hours for tests and waiting many days for the results. they're getting results back in eight days. well, eight days, that's not actionable information. you can't use that information any more. if the person was infected with covid—19, you've missed your opportunity to intervene and get them into isolation, so they don't infect their family members and co—workers. those who have lost loved ones in this sudden surge find ways to express their grief and their anger. sighs.

i don't want my father to just be another number. the reason why people are getting sick and numbers are skyrocketing here, and we are number one not only in the entire country, but the entire world, is not because of lack of individual responsibility. it's because of lack of leadership. and it's the tired hearts of medical staff that are breaking, as they're forced to make decisions they hoped they never would. sometimes you just have to go into crisis mode, and what that means is basically having to triage, like in a military setting, having to triage who gets to get that resource and who doesn't. but if you have very limited resources and you know a bunch of sick patients need it, you have to pick and choose who gets that life—saving intervention. that's a horrible situation to be in. i've never had to be in that situation. some hospitals here are now preparing to operate at up to 150% capacity — an indication that arizona is expected to continue to be the epicentre of this explosion

of new cases, and the impact on people across the state could get even worse. sophie long, bbc news, phoenix, arizona. let's get some of the day's other news. the number of people killed by the coronavirus in brazil has now passed 70,000. official figures show that 1200 people with covid—19 died over the past 2a hours. health experts say there's no indication that the spread of the virus is slowing down. hong kong's bureau of education has announced that all schools will be closed from monday because of a spike in locally transmitted coronavirus cases. the city reported 42 new cases on thursday, of which 3a were locally transmitted, marking the second consecutive day of rising local infections. reports from china say at least 144 people have died or are missing following days of intense flooding. four cities along china's yangtze river have declared severe flood warnings. nearly 300,000 people have fled their homes,

as houses have been destroyed, roads blocked and many left stranded without food or electricity. tropical storm fay has made landfall in newjersey. it forced the closure of a number of beaches while roads were flooded in ocean city. heavy rain also fell in new york city as the storm moved north. president trump was forced to postpone an election rally, due to take place in new hampshire. the united nations and the european union have criticised a decision by turkey to turn one of the world's most famous buildings, the hagia or aya sophia, back into a mosque. the world heritage site was originally built in the 6th century as a byzantine christian cathedral. the ottoman empire converted it into a mosque in the 15th century. it finally became a museum in the early 20th. from istanbul, 0rla guerin reports. change is coming to hagia sophia — jewel of the byzantine empire. a great monument to christianity conquered

by the ottomans, later a museum bearing testimony to layers of history. speaking turkish. but president erdogan, who presents himself as a modern—day conqueror, has announced a new chapter. "anyone who doesn't like it," he says — and plenty abroad don't — "is attacking turkey's sovereignty." under its soaring golden dome, hagia sophia will now become a mosque, as in 0ttoman days. but turkey says christian emblems, like mosaics of the virgin mary, will remain, and everyone will be welcome. making changes here is profoundly symbolic. it was kemal ataturk, founder of modern turkey, who decreed that hagia sophia should be a museum. now president erdogan is taking one more step to dismantle

ataturk‘s secular legacy and remold turkey according to his vision. and that's a vision that alarms the turkish nobel laureate 0rhan pamuk, who has gazed lovingly at hagia sophia from his balcony for the past 25 years. turks are proud to be a secular muslim nation. now, converting hagia sophia into a mosque will take away that pride from the nation. there are millions of secular turks like me who are crying against this, but their voices are not heard because we don't have enough free speech and democracy in turkey, unfortunately, any more. back at hagia sophia, british tourists visiting today were unconcerned by the change. that's just part of the history of turkey, and it's up to the turkish government, i think. i'd visit it whether it's a mosque 01’ a museum. it doesn't bother me. and you think it's for the turks to decide? absolutely, absolutely.

reclaiming hagia sophia plays well with the turkish leader's base, and distracts from the economic damage done by covid—19. but many in the international community say it belongs to humanity, and should have been left unchanged. 0rla guerin, bbc news, istanbul. the online retailer amazon says an email sent to its employees asking them to remove tik tok from their mobile devices was sent in error. an internal memo sent to staff earlier on friday had said employees should delete the video—sharing app over what it called security risks. the app is owned by a chinese company and justin sherman — a cybersecurity expert — says that there is a serious risk that tik tok could share user data with the chinese government. of course there is a risk. tiktok is a wildly popular app in the us, it is, as you said, owned by bytedance which is a chinese company. it is no secret that every

country in the world spies and many countries will tap internet and technology firms within their borders to do so. and so really the question with tiktok is how likely is it that the chinese government might be doing this and what cases might they be doing this? and then, on the policy end, what is the appropriate response that a government like that in the us can take to deal with it. is tiktok, though, more risky for a user than other apps made by western companies such as facebook? well, so, tiktok is not too different than many other apps in that they collect far more than what you would might expect on the application. so certainly, tiktok is collecting comments users post to videos they view but it is also collecting things like your contacts potentially or internet search history. maybe even what you had last in your clipboard, so what you are copying and pasting. this goes far beyond what most users might suspect but there are a lot of other apps that do this.

and so if we are just talking about the scope and the depth of the data that this app mines from users, it is really a systemic issue in the us with a lack of limits on what private companies can collect. we are in really new territory here, seeing powerful chinese firms, the one which owns tiktok and also huawei, now in conflict with western countries. what are we learning through this conflict? we are learning a couple of things. 0ne, we are seeing that many different countries all around the world, whether it is japan, or south korea, or india, or the us, are dealing with the same questions. when you have a global supply chain that is so interdependent and so interconnected, it is difficult sometimes to know what the right thing to do is when there are security risks. the other main lesson we have taken away from this is that even though there are real security concerns, potentially with tiktok and certainly

with the chinese telecom huawei, with the current us administration, these decisions are driven more by politics and looking tough with china rather than by security risks that may be in play. stay with us on bbc news. still to come: 80 years on from battle of britain, we tell the story of the schoolgirl who helped the raf beat the luftwaffe. after months of talks and missed deadlines, a deal has been struck to keep greece within the eurozone. the immediate prospect of greece going bust, in the worst crisis to hit the eurozone, has been averted. emergency services across central europe are stepping up their efforts to contain the worse floods this century. nearly 100 people have been killed. broadway is traditionally called the "great white way" by americans, but tonight it is completely blacked out. it is a timely reminder to all americans of the problems that the energy crisis

of thousands of bosnian muslims at the town of srebrenica. bosnian serb forces overran the town. it was the largest mass murder of the conflict. every year, the anniversary is marked by a mass gathering, but this year it'll take place with social distancing. allan little, who covered the bosnian war for the bbc, reports. it was the worst atrocity on european soil since the nazis — 8,000 men and boys separated from their families and, in the space of a few days, murdered and thrown into mass graves. a united nations peacekeeping force not only failed to stop it, it actively handed over thousands of bosnian muslims to their killers, led by the bosnian serb commander ratko mladic. the shared international shame of that echoes down the decades.

it is not as if we didn't know it would happen. many saw it coming, for mass murder had been part of the bosnian—serb military campaign for three years before srebrenica, a campaign they themselves called "ethnic cleansing". the crimes committed rank among the most heinous known to humankind... in the hague, mladic was one of several convicted of genocide. the yugoslavia tribunal was the first experiment in internationaljustice since leading nazis were tried at nuremberg. even with quite a considerable number of people who have been convicted — not only in the hague, but in the local courts as well — a considerable number of people who have been identified and found in these mass graves, there is still something really big missing, and what's missing is the recognition of their suffering and their pain. but genocide denial persists.

in our age of freely available alternative facts, many bosnian serbs refuse to acknowledge either the scale or the nature of what happened at srebrenica. that rewriting of history has already had deadly consequences. last year, a white supremacist murdered 51 muslims at friday prayers in new zealand. in the minutes before the murders, he'd been listening to a song glorifying the bosnian—serb leaders convicted of genocide — mass murderers, repurposed as heroic defenders of a white, christian, european heritage. emir suljagic survived the srebrenica genocide only because he worked as an interpreter for dutch peacekeepers there. the fate of the bosnian muslims is actually a rallying cry today, or a rallying point for extreme, right—wing, violent extremists. these are some of the wider ramifications of the denial of bosnian genocide, and they have come home to roost.

at srebrenica, they are still burying the dead. it has taken 25 years to find and identify some of the victims. about a thousand are still missing, and the survivors live in a world where some still say it's all been exaggerated, or never happened at all. allan little, bbc news. ghislaine maxwell, the former girlfriend of the convicted sex offenderjeffrey epstein, has strongly denied charges that she helped him sexually exploit girls as young as 1a — and even participated in the abuse. her lawyers have requested her release from a us prison on $5 million bail. 0ur correspondent nada tawfik has more. this court filing by ghislaine maxwell's attorney comes ahead of a court hearing planned for tuesday where a federaljudge will decide if she can be released from prison pending trial.

this is really an argument against the government's position that she's a flight risk. they say she is not a flight risk, that she hasn't left the united states in the past year and in fact, afterjeffrey epstein‘s arrest, she had actually reached out to prosecutors through her counsel. she said instead she should be released on bail with a bond of $5 million, that she would surrender her travel documents and not leave the new york area. and that she would also agree to home confinement with electronic gps monitoring. we know prosecutors are going to be arguing strongly that she should remain in custody given the horrendous crimes she faces and the lengthy amount of prison time if convicted, along with the three passports she has and her wealth. another interesting part of this court filing was that it really gave an insight into the defence's strategy.

what they said is that maxwell has been wrongfully substituted for the deceased — epstein. they say she is not jeffrey epstein and in fact she hadn't been in touch with him for more than a decade before his death. hundreds of people have gathered to pay their respects at the funeral of dame vera lynn, who died last month at the age of 103. the singer's cortege was accompanied by a battle of britain flypast as it travelled through her home village in east sussex. representatives from the royal british legion stood with flags as they waited to honour dame vera. stayng with the battle of britain, it's emerged that a schoolgirl from london had a hand in the raf‘s victory in that aerial fight. she helped to improve the firepower of the airforce's new fighters, the spitfire and the hurricane, which were key to defeating the german luftwaffe. sophie raworth explains. newsreel: way up in the sky there are messerschmitts, junkers, heinkels and dorniers,

that are going to get the thrashing of their lives. july, 1940, and nazi germany is beginning the first of many bombing raids in what became known as the battle of britain. but the raf‘s pilots managed to fight off the luftwaffe and defend these shores in their spitfires and hurricanes. it is the most famous plane from world war ii. it played a crucial role in the battle of britain. but what we didn't know until now was the role that a 13—year—old girl played in its design. this new generation of fighter plane had originally been designed with just four machine—guns. but this man, captain fred hill, a scientific officer in the air ministry, became convinced that four guns would not be enough. each plane needed eight. he faced stiff opposition. most thought eight guns would be too many, impossible to fit on the planes, but captain hill was convinced he was right, so he turned to an unlikely

person for help — his 13—year—old daughter, hazel, a talented mathematician. together, around their kitchen table, they worked through the night on complex calculations to prove that eight guns firing at least 1000 rounds a minute was essential for success. they talked about burning the midnight oil and coming into the office late after everybody‘s gone, to carry out further calculations and borrow some bits of equipment to carry out experiments, more or less off their own bat, working very long hours because they were really dedicated to these things. and of course, people taking their work home. hazel told her sons about her role when they were growing up. amazing that history hangs on so fine a thread. you know, if she got the calculations wrong or if she hadn't been asked to help, and the decision had not been made to go with eight guns, who knows what could have happened. this graph, presented to the air ministry in 1934,

was the result of hazel‘s calculations. with eight guns firing, the fighters typically had just two seconds to hit their target before pulling away. they had to get incredibly close to the enemy planes, just 250 yards away, to stand a chance of shooting them down. hazel‘s calculations meant the government changed its mind. the battle of britain proved to be a turning point in the war. it was the bravery and success of the pilots that made victory possible, but without the support of many others, the battle may not have been won. what a great inspiration for young people today, young girls in particular, that can look upon someone like hazel in the early 1930s making such an important contribution 80 years after the battle of britain, hazel hill is finally getting the public recognition she deserved. sophie raworth, bbc news.

as the day wears on. look closely — there may be one or two showers in north—west england, northern ireland and scotland. even in these areas, the majority will stay dry. a noticeable west or north—westerly breeze. temperatures just a touch below par for this time of year, but in the sunshine, it won't feel too bad, 17—21 celsius. a bit of rain will skip across 0rkney and shetland during saturday night. otherwise, it's dry with clear spells into the early hours of sunday. another rather cool start on sunday morning, but with our area of high pressure still in charge it going to be another dry day for most. the high pressure centre down to the south, where we'll have the best of the sunshine. more cloud further north, and behind me, you can see this frontal system. that will introduce something of a change very late in the day to northern ireland and western scotland. some splashes of rain getting in here by the very end of the afternoon, but for most, it stays dry. it's a warmer day

on sunday as well. 19 degrees for glasgow, 23, maybe 24 down towards the south and the south—east of england. 0ur area of high pressure tries to hold on into monday, but i think this frontal system will make some progress south—eastwards, bringing some splashes of rain on and off, the rain quite showery, quite sporadic in nature. there will be some dry spells as well. towards the south—east of england, it should stay dry for a good part of the day. still warmer here, but slightly cooler and fresher further north and west. through the week ahead, there is going to be a lot of dry weather. there'll be some spells of sunshine, the warmest weather down towards the south. some rain at times, most of that towards the north and the west.
