this is bbc news. i'm kasia madera. our top stories: all change at the top of the white house. donald trump replaces his chief of staff, reince priebus, with the current homeland security secretary, john kelly. after north korea test—fires a second intercontinental ballistic missile, the us and south korea react with a live—fire exercise of their own. charlie gard, the terminally ill british baby at the centre of an international row over his treatment, has passed away. and remembering the fallen of world war i: commemorations for the 100th anniversary of the battle of passchendaele. hello and welcome. the revolving doors of the white house are in action again. the latest person to be packing

up their desk is the chief of staff, reince priebus. the announcement comes a day after the new white house communications director, anthony scaramucci, accused him of leaking information to the media. mr priebus‘ replacement is the current director of homeland security, retired generaljohn kelly — a man the president described as a ‘great american‘ and a ‘true star‘ of his administration. well, after president trump tweeted the news of priebus‘ departure, he 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 far, respected by everybody, a great, great american. reince priebus, a good man. thank you very much. and within the last hour, he has been speaking about his resignation, which he says he offered on

thursday. here's what he had to say. it was something that i have always talk to the president about, which is, i have or are said to him, and he was agreed with me. any time either one of us think that we need to make a change or need to move in a different direction, let'sjust talk about it and get it done. so i think the president thought about that and we talked about it yesterday, and i resigned, and he accepted my resignation. but this is about the president. it is about moving his agenda forward. i think he's made a smart decision withjohn kelly. i am looking to the future. i will always be a donald trump band. iamon will always be a donald trump band. i am on the train trump. i am looking forward to helping him achieve his goals for the american people. our north america editorjon sopel has been following events in the white house.

i think reince priebus struggled to assert himself in that white house to bring order and discipline, to bring a chain of command, if you like. and i'm sure people will be looking to general kelly to achieve that which has not been seen in the previous six months. whether donald trump will change in style, that is another question. whether he will be at the. the leaks is another thing i think donald trump would want to be able to do. but it is interesting. you would hardly say that anthony ska ra you would hardly say that anthony skara mucci, appointed a week ago, and general kelly, appointed just now, a cut from the same cloth. they seek to represent two different styles of doing business. —— scaramucci. how many times have we said in the last 18 months this might bring change in the modus operandi of donald trump. nothing will change it. his 71 years old and he will not change. —— years. around

the edges, maybe there will be a touch more discipline, but i suspect what you lose with reince priebus is the establishment republicans in the white house having been purged. sean spicer went last week, and he was pa rt spicer went last week, and he was part of the establishment. you've seen reince priebus, and his deputy few months ago. they seem to represent the old—fashioned republican party and that way of doing things. now you have people who are military or very wealthy. and those of the two people that are represented in the white house now. and we will see in the coming months whether it brings a change in the way this white house operates and whether it brings a change to the russian operation. but that is already rolling. there is a special council. it will be very hard to say, just because you have a new chief of staff, all right, we are going to cancelled the russian investigation. —— cancel. well from internal battles at home to a crisis brewing

on the international stage. the pentagon has confirmed that north korea has fired off its second inter—continental ballistic missile in less than a month. it landed in the sea off the coast of japan. in response, the us and south korea have conducted live fire exercises with surface—to—surface missiles. north korea's leader kimjong un is claiming that the latest test, north korea's leader kim jong—in is claiming that the latest test, as he put it, "proves the entire us territory is within striking range". karen allen is watching the situation from seoul and gave us this update. we have had a strong response overnight from president been here. we mentioned the live firing exercise that had happened. they happen pretty swiftly after the firing of the missile. —— president moon. it is a bottler we saw a month ago, because of course is missile testis ago, because of course is missile test is the same type of missile that we sought tested on the fourth ofjuly. it is an intercontinental ballistic missile. president moon here also tried to put pressure to speed up the rollout of the missile defence shield here. that is a

controversial project. china has been particularly concerned about that because of worries about spying capacity. but nevertheless, president moon has been concealed in the past, but indicated that need to be speeded up quickly. —— conciliatory. we had a meeting of the night of the national security council here in seoul. and wheels are heard from president moon saying that the un security council must 110w that the un security council must now quicken the pace of trying to have a fresh security council resolution pushing tighter sanctions against north korea. we have a ready scene this week in the united states, is pushing through a bill which would include tighter sections, particularly on shipping and forced labour inside north korea. basically trying to cut off the streams of funding which are thought to supply pyongyang's nuclear programme. what we are hearing to night out of seoul is a

desire by the president for the un to ta ke desire by the president for the un to take a lead and try and get cover sanctions. the big question there is whether china, but even more so russia, will sign up to security council resolutions that tightened sanctions. —— that titan sanctions. —— tighten. earlier, japan's minister for public affairs, shinichi iida gave his reaction. he stressed that pursuing economic sanctions, rather than military options, should be the main focus of the response to north korea. shinzo abe has expressed again and again that the japanese government supports the drop administration's suggestion that all options are on the table. there is no question about it and we will continue to support key allies like united states and south korea. but at the moment, it is important to recognise that military options are the last

resort. what is important right now is to implement rigourously and com pletely is to implement rigourously and completely economic sanction measures that were brought by the security council, which also include russia and china, which have great influence over north korea. so that was the japanese minister for public affairs said that military option should be the last option. we are getting information from south korea's defence minister say that they will prepare independent measures to curb the north korean nuclear threat. those measures as soon north korean nuclear threat. those measures as soon as north korean nuclear threat. those measures as soon as possible. that reaction just measures as soon as possible. that reactionjust coming in measures as soon as possible. that reaction just coming in from south korea's defence minister. we will keep you updated as and when we get more reaction. but for now, let's look at some of the other stories making the news. police in venezuela have clashed with opposition activists who blocked roads in the capital, caracas, in protest against sunday's vote to elect a new assembly that will re—write the constitution.

at least two people were injured as police fired rubber bullets and tear gas. the government of president nicolas maduro banned protests ahead of the vote, which the opposition is boycotting. police in germany say a man armed with a knife has attacked people in a supermarket in the northern city of hamburg. one person was killed and four others injured. the suspect, now in detention, is a 26—year—old man born in the united arab emirates. the police say they have no clear idea of the motive. there have been clashes between police and protesters in north london. the metropolitan police say that disturbances have continued with officers deployed to the area on horse back and in riot gear. 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. charlie gard, the british baby at the centre of a legal 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 looks back at the story which captured attention around the world. 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. fergus walsh, bbc news. stay with us here on bbc world news, coming up, a look back at a wild week for american health care as we follow the ups and downs for obamacare and trumpcare. cheering the us space agency, nasa, has ordered an investigation after confirmation today that astronauts were cleared to fly while drunk. the last foot patrol in south armagh.

once an everyday part of the soldiers' lot, drudgery and danger, now no more after almost four decades. if one is on one's own, in a private house, not doing any harm to anyone, i don't really see why people should wander in and say, you're doing something wrong. six rare white lion cubs are on the prowl at worcestershire park and, already, they have been met with a roar of approval from visitors. they're lovely, yeah. really sweet. yeah, they were cute. this is bbc news. the latest headlines: after a tumultuous few days at the white house, reince priebus is leaving as chief of staff to the president. generaljohn kelly will take over. north korea has test—fired an intercontinental ballistic

missile for the second time this month. neighbouring countries have condemned the launch as a "severe and real" threat. it has been a wild time at the white house. there have been feuds between president trump and his attorney general, jeff sessions. we are still waiting to see how that one is resolved. and two of his own top staffers appeared to be at war. that has ended with reince preibus stepping down. but the chaos doesn't end there. it spreads to capitol hill, with the republican attempts to repeal obamacare. here's a look back at the week. healthcare. obamacare. repeal and replace. health-insurance. the motion to proceed... legislation... the skinny bill. it is not agreed to. any senator voting against

starting debate is telling america you are fine with the obamacare nightmare. we have obligations to keep those commitments, both to begin the debate and ring smarter healthcare solutions to the desk of the president. —— bring. healthcare solutions to the desk of the president. -- bring. it is not a good approach for legislation that affects millions of people and one sixth of the economy. mr mccain, aye. we should trust each other and return to regular order. we are getting nothing done, my friends, we are getting nothing done. equally divided. the vice president votes in the affirmative and the motion is agreed to. i want to thank senator john mccain, a very brave man, who

made a tough trip to get here and vote. on this vote, the ayes are 43, the nos, 57. it falls. there are many republicans who don't like this bill. anyone who thinks it is over is sadly mistaken. are you pleased? on this vote, the ayes are 45, the noes, 55, the amendment is not agreed to. we have been asked by the leadership for days to vote on the least common denominator, the skinny bill. the devil is always in the detail. what does skinny repeal

mean? we have to have republicans and democrats sit together and come up and democrats sit together and come up witha and democrats sit together and come up with a bill that gets a majority in both houses. i am not supporting the legislation as it stands today. without objection. so, mr president, this is clearly a disappointing moment. i imagine many of our colleagues on the other side are celebrating. i want to say again, i am proud of the vote i cast tonight. bernie! bernie! it is consistent with what we told the american people we would try to accomplish in four straight elections. supporters of pakistan's former prime minister nawaz sharif say he will use all the legal options available to defend his name.

mr sharif was forced to resign, after the supreme court disqualified him from office for life over corruption allegations. it's the climax of a saga prompted two years ago by the panama papers, leaks which linked mr sharif‘s three children with offshore companies that allegedly enabled money laundering or tax evasion during the buying of expensive london property. our pakistan correspondent, secunder kermani, reports. they've been chanting "go, nawaz, go" for over a year. and today, he left. nawaz sharif resigned after pakistan's highest court disqualified him from holding office. judges decided he'd not been honest in dealing with a corruption inquiry. for his opponents, including cricketer turned leading politician, imran khan, today's decision is an unprecedented victory for accountability. translation: for the first time, we're hopeful that we can also progress like other countries. a powerful man has been brought down by the authority of law. this is not a personal issue between me and nawaz sharif,

it's about the future of pakistan. this case centres around four luxury flats in this building in mayfair. it began when millions of secret documents from a law firm in panama were leaked last year. they revealed the flats were linked to a number of nawaz sharif‘s children. the supreme court in pakistan has been trying to establish where the money to buy them came from. the prime minister's daughter is alleged to have tried to cover up her ownership of the flats. maryam nawaz had been seen as her father's successor. now they both face further inquiries by the national anti—corru ption body. she was defiant on twitter, though, posting this picture of the prime minister, promising he would return to power in next year's elections. no prime minister in pakistan has ever completed a full term in office. nawaz sharif himself was overthrown by a military coup in the 90s. some of his supporters claim pakistan's army is the driving force behind the current allegations.

sharif, his family and his allies have always denied any wrongdoing. we have history of such disqualifications in pakistan and we have also seen that such disqualifications are later turned down and they are reversed. the ruling party will now have to nominate a new leader. amongst the favourites is the prime minister's brother, currently chief minister of the province of punjab. but, for the moment, the country is facing real uncertainty. secunder kermani, bbc news. as we heard there, mr sharif was forced to resign, after the supreme court disqualified him from office for life. pakistan's ambassador to the united states, husain haqqani explained how this will be seen in pakistan. there will be a period of instability. more importantly,

pakistan in a negative way reaffirmed the tradition that no pakistani prime minister ever leaves office as the result of an election. they are elected to office, but they are either assassinated, removed from power by the president, a civil servant, they lose power in a coup that are, and now you are seeing the second being removed in a traditional coup. —— coup. that does not mean he is guilty of corruption, but the fact remains that it should be determined in a trial court, and this is not a trial. this weekend commemorations will be held in the uk and belgium marking the 100th anniversary of the beginning of the third battle of ypres, also known as the battle of passchendaele. three months of fighting killed or injured more than 450,000 men on both sides. when it was over, the allies had gained five miles of german territory. our special correspondent, allan little, reports from flanders,
