this is bbc news. the headlines at 11pm: charlie gard, the baby at the centre of a high court battle over his care, has died. his mother connie yates says, "our beautiful little boy has gone. we are so proud of you, charlie." after a bout of internal squabbling at the white house, president trump replaces his chief of staff. 82 tower blocks are deemed to have failed a new government fire safety test following the grenfell tower tragedy. and on newsnight, we learned today that a government fire test on exactly the same cladding and insulation combination as grenfell tower, supposedly fire resistant for a0 minutes, burned injust nine minutes. we'll have all the details. good evening and welcome to bbc news.

it's been announced that charlie gard, the baby who was at the centre of a high court battle over his care, has died. the 11—month—old was moved to a hospice where his life support was removed. a statement from his family said, "our beautiful little boy has gone. we are so proud of you, charlie". our medical correspondent fergus walsh now looks back at the story of the child whose plight became an issue of international concern. today, charlie is two weeks old. this is charlie gard without breathing or feeding tubes. born apparently healthy, but soon a devastating genetic condition emerged which causes progressive muscle weakness. by his side throughout have been his parents, connie yates and chris gard. charlie was transferred from intensive care

at great ormond street hospital, where he spent ten months, to a hospice, where he died earlier today. they'd fought a lengthy battle to keep charlie alive, refusing to accept he had suffered catastrophic brain damage. and they raised funds online for experimental treatment in the united states. great ormond street applied to court to end charlie's life—support, and everyjudge backed them. at the uk supreme court, with charlie's parents sitting behind, the hospital's barrister said his suffering should end. the reality is that charlie can't see, he can't hear, he can't move, he can't cry, he can't swallow. immensely sadly, his condition is one that affords him no benefit. an american doctor offering to treat charlie with this experimental powder had not seen his full medical records and it took six

months before he came to london to examine him. finally, on monday, at the high court, charlie's parents abandoned their legal fight to keep him alive, saying that time had run out. our son is an absolute warrior and we could not be prouder of him and we will miss him terribly. his body, heart and soul may soon be gone, but his spirit will live on for eternity and he will make a difference to people's lives for years to come. we will make sure of that. shame on gosh! a private family tragedy was fought out in public. even the location and timing of charlie's death became a matter of dispute. doctors and nurses at great ormond street, one of the world's most renowned children's hospitals, received abuse and even death threats, which charlie's parents condemned. let us pray... pro—life groups adopted the cause and charlie's plight became

an international issue when both the pope and donald trump tweeted offers of help. the judge said it was a pitfall of social media that people commented without knowing the facts. charlie died a week before his first birthday. his parents said they were sorry they could not save him, but would set up a foundation in his name to help other sick children. president trump has replaced his chief of staff, reince preibus, a day after the new communications director at the white house accused him of leaking information to the media. anthony scaramucci also described mr preibus as a paranoid schizophrenic. mr trump announced the change at the top of his team on social media. after he tweeted the news the president had this to say

upon returning to washington. reince is a good man. john kelly will do a fantasticjob. general kelly has been a star, done an incredible job thus kelly has been a star, done an incrediblejob thus far, kelly has been a star, done an incredible job thus far, respected by everybody, a great, great american. reince priebus, a good man. thank you very much. we'll have more from our washington correspondent laura bicker shortly. we're hearing reports of a stand off between police and protestors in dalston in north london. it follows the death of rashan charles who was killed last saturday. unverified footage on social media appeared to show at least one police officer attempting to restrain mr charles on the floor of a shop the metropolitan police have said disturbances have continued with officers deployed on horseback and on riot gear. cash in. —— in.

on the line is alex collins, a bbc journalist. things have calmed down from half an hour ago. 50 riot officers are in dalston in front of a series of buses. there are a group of protesters or people running up the street away from the police looking like they are being pushed back. things have calmed down. there's a lot of anger about what happened in the previous week and a lot of people want answers. this is a

lively area of north london and they are used to crowds on the street at this time of night. it's different from a normal night in dalston. as i walk up the street to the right, looking at the shopping centre and all the windows have been smashed open. it doesn't feel as tense as we remember with the riots in tottenham but it's certainly been a night of unusual activity in the area. alex, thanks to match, alex collins reporting from dalston. 82 buildings have failed a new fire safety test in which insulation and cladding similar to the type fitted at grenfell tower were tested for the first time. 47 of those buildings are owned or managed by local authorities or housing associations. the government today also announced an independent review of building regulations and fire safety. at least 80 people died in the grenfell tower fire last month.

our home affairs correspondent tom symonds reports inside the burn hall, this is where the tests have been taking place, upon which the fate of dozens of tower blocks hang. so far, the government's refused to release video of the tests, but like this, it involves setting light to cladding and insulation fitted to a nine metre wall. test number one of a design identical to that at grenfell tower, was supposed to last a0 minutes — it was stopped before nine. the flames had reached the top of the test rig. the landlords of 82 buildings, 47 of them social housing, will now have to take urgent action. in salford, anticipating a test failure, cladding is already being taken down. the thought of it not being safe and you're sleeping in bed of a night time, thinking that's not safe...

do you know, it's bad, isn't it? really bad. they should take the lot off, i don't care how much money it costs. it's not money, it's people's lives at the end of the day. the new full—scale tests are designed to replicate the way in which grenfell tower was refurbished, with a cladding system to improve the insulation and the look of the building. it's the bits that make up this system that are being tested together, to see how well they prevent fire spreading. the cladding itself is basically a sandwich, thin sheets of aluminium with plastic as the sandwich filling. and then there's an air gap, designed to improve ventilation, but did it fuel the fire? behind that, thick blocks of foam insulation. how well did they withstand the flames? the tests involve using various brands of cladding and insulation, to examine how they perform in a fire. these new tests were ordered because when sections of the cladding were tested on their own, they failed spectacularly. the government hasn't allowed us to film any of those tests, so we obtained piece of reynobond pe, the same cladding used at grenfell tower, and asked a company specialising in plastics to show us how it reacts to fire. when the flame was applied

to the aluminium sides... no problem. but when the sample is turned, so the flame hit the plastic filling in the aluminium sandwich, this is what happens. several tests showed, in similar temperatures to the grenfell fire, it drips burning plastic. if you clad a building in it, you've got a fuel main source for a frame to propagate on. if you do a small—scale fire test, it's not necessarily representative of what will happen on a full—scale building. which is why the government is now doing full—scale tests, but three separate sources with direct knowledge of the type of cladding used at grenfell tower, have told the bbc it has never been subjected to the full—scale test. investigators are examining what fire assessments were done.

the regulations say when there is a proposal to use flammable material on a tall building, there should be an actual fire test or a desktop study, based on previous test results. building control inspectors say the regulations are a mess. we've arrived at a situation where we have a series of different pieces of legislation, we have a series of different tests which can be applied to that legislation. we've created a system of cracks and shadows that people can either fall into inadvertently, or perhaps hide in the shadows on purpose. today, a new independent review of fire safety was announced, to look into those cracks and shadows. tom symonds, bbc news. as well as continuing problems for donald trump on his domestic agenda, another pressing issue is north korea. the pentagon announced tonight that pyongyang has tested another ballistic missile, which landed in the sea off the coast of japan.

rupert wingfield—hayes is in tokyo tonight. it looks like this was the same type of intercontinental ballistic missile that was launched by north korea back onjuly the fourth, missile that was launched by north korea back on july the fourth, that it flew for about 45 minutes and splashed down in the sea ofjapan off the northern japanese island of hokkaido, having flown about 700 miles. but what's really significant about this is how high this missile went. the latest estimates are it went. the latest estimates are it went up into space about 3000 kilometres or maybe 2000 miles, and that's very significant because it means it could reach as far as the mainland united states, perhaps as far as los angeles or chicago. that means an ability to strike the mainland united states. japan's prime minister shinzo abe has condemned this launch, he says this

clearly shows the threat to our nation's safety is severe and real. but this missile launch is really a challenge to president trump because it shows that a nuclear strike on an ability to strike the us with nuclear weapons by north korea is not far off, and president trump has said that he will not allow that to happen. let's return to the news that president trump has sacked the white house chief of staff, reince priebus, and replaced him with the director of homeland security secretary, john kelly. it comes amid reports of in—fighting between member of the president's top team. and laura bickerjoins us now from washington. he did it by social media, is that true? yes, it was announced via twitter within the last hour or so. yes, this is a white house that not only feels like a revolving door

over the last week, it is one that his personal changes have been announced on twitter. why has reince priebus gone? he was a republican establishment figure and he came very late to the donald trump campaign, just right at the very end, and there were reports during that time that he asked crumpy to tone down some of his rhetoric. now, that's just not donald trump's style at all —— donald trump. look at who he appointed the new director of communications, antony scaramucci, this flamboyant figure from wall street who has come in in the last week and certainly used colourful language over the last 2a hours to describe reince priebus. he even indirectly accused him of leaking information about the trump administration to the press. now we have reince priebus, whojust a few hours after that report came out, reportedly resigned, donald trump

announced that now. when it comes to why reince priebus is out the door, it doesn't seem like he had the ear of the president or the confidence of the president or the confidence of the president and there's one thing we know donald trump values and that is loyalty. reince priebus‘s loyalty is to his party. when it comes to donald trump, he's looking to surround himself and separate himself from politics and bring in people from the real world. first of all antony scaramucci, and now as white house chief of staff, this high—profile will go to a a—star marine general, john kelly. who will be in charge of homeland security? that is yet to be appointed. we will have to keep an eye on twitter to find that out. but when it comes to his appointment, he is cut from the same club as donald trump. he is outspoken,
