and possibly out of the race, too. good evening. president trump has urged china to put what he called "a heavy move" on north korea, after the regime said it has successfully tested an intercontinental ballistic missile capable of carrying a nuclear warhead. pyongyang claims the missile could strike anywhere on the planet. western scientists are more sceptical, but say it could possibly reach as far as alaska. the launch is just days before world leaders meet to discuss, among other things, north korea's weapons programme, which it's pursuing despite international sanctions. our diplomatic correspondent james landale reports. this is the moment that north korea says it came a major power, the launch of a missile which it says can deliver a weapon as far away as the united states. the news was announced on state television with barely constrained joy. the presenter showing the handwritten order given by the country's leader, kim jong—un. he personally supervised the launch of a missile which he believes will secure him in power, protect his people and dismay his opponents to the south. translation: if north korea ignores oui’ translation: if north korea ignores our military‘s warning and continues provocations, we clearly warn that kim jong—un‘s regime will face destruction. this is the missile which could carry the regime's nuclear weapons. it was launched from an airfield here in the west of the country. it was sent up at a very deep angle and it rose, it is claimed, to about 1700 miles, thought to be the highest any north korean missile has got to. it landed 37 minutes later, more than 500 miles away, somewhere in the sea close to japan. the point is that if this missile were fired at a shallower angle, it might now have the power to reach, potentially, more than 31100 miles, the minimum defined range for an intercontinental ballistic missile. if so, that could mean reaching as far as alaska on the mainland of the united states. they're so keen on developing more advanced missile capabilities. although right now, the region is targetable, it is about ensuring that they have that level of respect internationally, to say, we have this capability, stand up say, we have this capability, stand up and listen to us. experts say it is not clear if north korea has the technology needed to protect a warhead on re—entry and guide it to its target. but the possibility of north korean missiles reaching the us isa north korean missiles reaching the us is a significant step forward, which president trump said earlier this year just wouldn't which president trump said earlier this yearjust wouldn't happen. in a tweet, he again urged china to put pressure on north korea to end this nonsense, once and for all, a message echoed by allies. the government will be escalating this at the g20 and the un in the next few days. but the real pressure has got to come from china. but so far, china has been reluctant or unable to turn the screw on north korea. the chinese president was in russia today. both he and president putin called for a freeze on north korea's nuclear weapons programme, but also the suspension of us and south korean military exercises. the supreme leader is enjoying his growing nuclear capability and shows little sign of listening to anyone. the balance of power is shifting in the region, and the outside world seems powerless to stop it. in a moment, we'll speak to our china editor, carrie gracie, but first, let's speak tojon sopel, our north america editor, who's in washington tonight. trump said four days ago that his patience is over with north korea, so what is he going to do now? blu ntly bluntly fiona, blu ntly fiona, there bluntly fiona, there are no easy solutions. if there was a piece of low hanging fruit that could be easily plucked, us policymakers would have done that by now. we know that strategic patience has run out. we have heard in the past few days that sanctions are going to be imposed on a chinese bank, and imports and exports which are believed to be helping john theirs. first of all, donald trump said he was going to go it alone, no—one knew what that meant. then he became suddenly best friends with the chinese president after his visit, and we were going to rely on the chinese. but that seems to have led toa chinese. but that seems to have led to a certain amount of disillusionment and the call for the chinese to do more. look at the other weapons in the armoury? isolate north korea 7 other weapons in the armoury? isolate north korea? that has been done. sanctions? there are already sanctions. call for an emergency meeting of the security council? america has done that today as well. if it is true that it has been an intercontinental ballistic missile which has been launched, it is a game changer. but for all the huffing and puffing, there are no easy policy solutions. carrie in beijing — what is china's response, what is it doing to rein in its neighbour? china would say that it has observed un sanctions against north korea by most notably suspending coal imports from north korea earlier this year. it would say that it is doing its best to get the parties around the table, proposing a freeze on the north korean missile programme in exchange for a suspension of us and south korean military exercises. could china do more? clearly, it could. china controls about 90% of north korea's trade with the world, including most of its energy and most of its food imports. the fact is that china is now increasingly good at getting other governments to do what it wants when it takes something seriously. so, you have to conclude that this is not a top priority for the chinese on the korean peninsula. what they most wish to avoid is a reunified korean peninsula, allied with the united states. and they won't do anything which threatens that. the terror attack on the ariana grande concert at manchester arena in may left 22 people dead. the youngest victim of the bombing was just eight years old. saffie roussos, whose mother is still being treated in hospital, would have been nine today. her family has spoken to the bbc about what happened that evening and about living with their loss. judith moritz went to meet them. singing v0|ceover: saffie roussos shone. always singing and smiling, she loved music, and couldn't wait to see her idol onstage. you couldn't be out with saffie without having fun. but her dream was to be famous. it was her everything, and we bought her the tickets for christmas. she was just counting the days, the seconds, and it was just ariana grande ‘til nine, ten o'clock at night, and she would sing and dance every single song. she was ariana grande obsessed, so, to see how happy she was, it wasjust... obviously, i had to go with her. you were watching her watching ariana ? pretty much, yeah. she kept going, "come on, ashlee, you promised me you would get up and dance!" so we had a little dance. and she wasjust so happy, just elated all night, grinning. saffie was at the concert with her mum, lisa, and sister ashlee. they were all caught in the blast, just as the rest of the family arrived to meet them. i remember i was thrown to the ground, and then my next instinct, ijust sort of rolled over and crawled, because i couldn't walk. for you that night, andrew — had you come to the arena to collect? what were you doing? we were sitting there, weren't we? forjust a few minutes, and didn't hear anything, but just. .. just hell broke loose, just people, children, screaming, crying. and then, as i turned round the corner, i saw ashlee outside injured. and when did you learn about saffie? the detective that i spoke to in the hospital, he went away and he came back about 12, half 12, and told me. and you've all had to cope, haven't you, with saffie's loss and also lisa's recovery? yeah. how is she doing? she's fighting. i mean, she's got that many injuries around her body, just that alone. she's like a soldier. yeah. the world knew what had happened. lisa was not conscious. no. and when she came round, you had to tell her. no. she looked at me and said to me, "saffie's gone, isn't she?" i was dreading it. she just looked at me and said, "she's gone, isn't she?" and i said, "yeah." she goes, "i knew." do you have thoughts about the person who did this? no. i've not seen pictures, i don't want to know. i'm not interested. it doesn't mean anything to me. no, same here. if i could think about it, analyse it, break it down, sort it out and get saffie back, i'd do it — but i can't. how are you finding it, xander? there's times when you're sad, and times when you're happy, so it's kind of like a mix. you met ariana grande — tell me about that experience. i wanted to meet her to tell her what saffie meant to her, and i wanted to tell her from a father's point of view that she's got nothing to be sorry for. she's got nothing... you know, it wasn't her fault. saffie's family say she'd have been a star one day. now, her name is known, but for the saddest of reasons. we've lost everything. we have, because life willjust never be the same. the family of little saffie roussos there — speaking to our correspondentjudith moritz. even before the grenfell tower inquiry has got underway properly, there's growing pressure on thejudge leading it to step down. the labour mp for kensington, emma dent—coad, says sir martin moore—bick lacks credibility with local residents. and the london mayor, sadiq khan, has also warned that thejudge urgently needs to improve relations with the community. our home editor, mark easton, has been getting the views of residents and politicians alike. grenfell tower is black with urgent and unanswered questions, the community in its shadow seeks answers, but many say they don't have confidence in the man the prime minister has appointed to head the public inquiry. sir martin moore—bick, cambridge—educated and called to the bar in 1969, is a formerjudge. but his professional and establishment credentials don't impress the area's local labour mp, who says he should quit now. we don't have anybody we can trust there, and some of the groups are refusing to cooperate with the inquiry, and what kind of inquiry is that? there is no inquiry at all if people refuse to cooperate with it. i understand that. these people have been totally let down and betrayed. sir martin moore—bick hasn't even started his inquiry, and yet chris, a local charity worker who lost a close friend in the fire, reflects the views of many here. if we can't get someone that can empathise or understand the feeling of the people they are representing, and the people they are going to interview, because he is going to interview witnesses, he needs to know where they are coming from. if he doesn't have that kind of background, it will be difficult for him to start to even begin to imagine. the london mayor, sadiq khan, echoed by the labour leaderjeremy corbyn, is not calling for the inquiry head to go, but says he must win the community's confidence. former attorney—general dominic grieve believes sir martin must be allowed to get on with the job. i think we should be a little bit careful about reacting and saying that somebody else has got to be provided. the problem is, once we start going down this road, there's potentially no stopping it. this community has long felt marginalised from those who have power over them — respect and trust are always in short supply. and this tragedy has served to diminish those priceless commodities still further. in one of the flats right beneath the tower, i met beinazir, a mum with a couple of preschool kids who is also a local labour councillor. she says the borough's conservative leader, newly appointed, also faces an uphill struggle to win the trust of people in this ward. why would anything change now? i mean, what will it change? the fire might change things? well, i would hope so, but i am quite doubtful because i already feel like they are beginning to cover up a lot of things. this is a community still grieving, still in shock. i think, what must they have gone through while i was stood down here, helpless, me and my neighbours, all of us were stood helpless, just completely helpless. it's tough. the emotional and physical needs of those touched by the tragedy are still being dealt with. the grenfell fire response team said today it has now fulfilled the promise to offer all those made homeless by the tragedy rehousing within three weeks. but the vast majority, including this family, have not accepted what's being offered to them. i told you, i'm not going nowhere. i'm not going from this area. and then they offer you, you don't like it, you don't take it, you're going to be on the street. there's no more, there's no more. building the strength and trust needed to move forward from this tragedy is going to take courage and commitment. the bbc‘s panorama programme has found evidence of repeated cover—ups of child sex abuse in britain's cadet forces. victims have revealed how as far back as the 1980's senior cadet leaders dismissed complaints — and pressurised families into not going to the police. according to the ministry of defence, in the past five years alone, over 360 allegations of abuse, both historical and current, have come to light. over 280 have been now referred to the police. and 99 volunteer workers have been dismissed. katie razzall has more. join the cadets was the message in this recruitment film from the late 1970s. the youth organisation overseen by the ministry of defence was often aimed at children from deprived backgrounds. for difficult or distressed youngsters coming in they can immediately identify and feel secure. tonyjoined the cheshunt sea cadets to keep him off the streets, but he was sexually abused on a trip with the unit in 1981. there was a sensation and i woke up and there he was. i think he was actually crouching down by the bed and he stood up as soon as i woke up and i looked down and i was exposed, you know, and there was no doubt in my mind that... you know, he was touching me. the abuser was his commanding officer, lieutenant commander alan walters, then aged 33, a volunteer cadet instructor in charge of children aged 12 up. when tony's parents complained they got a visit at home from senior sea cadet officers in full uniform. we was ready to go to the police and they convinced us we should not go to the police. in return for not pressing the complaint, tony's parents say they were promised alan waters would never work with children again. but panorama has discovered that was a lie. waters was not dismissed, he was actually promoted and put in charge of ten sea cadet units. he spent a further 23 years with the organisation. our investigation found in cheshunt, glasgow and birmingham too a pattern. cadet leaders sexually abused children in their care and senior cadet officials then covered it up. it is being compared in scale to other sex abuse scandals. in tony's case, 25 years later alan waters and a naval friend were convicted in india of raping and abusing street children at an orphanage in mumbai. it made us feel terrible because we thought if perhaps we had gone to the police, we could have saved that happening. i don't know. the sea cadets have apologised unreservedly and have said the alan waters case is not reflective of the organisation. 130,000 young people are members of the three cadet forces. the ministry of defence told us child sexual abuse is an abhorrent crime and we have robust procedures in place to protect cadets. this includes all adults who work with children undergoing mandatory security and background checks, rigorous disclosure procedures and regular safeguarding training. the mod has so far paid out more than £2 million to survivors of cadet abuse. katie razzall, bbc news. and you can see panorama after your local news at 10.45pm on bbc one. it's on at the later time of 11.10pm in northern ireland, and 11.a5pm in scotland. most cancer patients should be offered genetic tests within five years to help create more effective, personalised treatments. that's the ambition outlined by england's chief medical officer. in her annual report, professor dame sally davies says there needs to be a national network of genome testing which could bring about a step change in medicine. here's our medical correspondent fergus walsh and his report contains some flashing images. hello, mate. could i have two cappuccinos, please? cancer runs in toby knight's family. both his parents died from it and he was diagnosed with colon cancer four years ago. now, he's one of 31,000 patients who have had their entire genome mapped by the nhs. i'm very excited about it. for me, hopefully, if my cancer decides to come back, it will benefit me. more importantly, it will benefit a lot of other people, forfuture generations, for better treatments, for quicker treatments, better diagnoses. dame sally davies says genome testing is still a cottage industry. she wants dna analysis to be the norm for cancer patients within five years. patients will benefit if we can offer them the scan of their genome that'll make a difference to their treatment. that's clearly all people with rare diseases, of whom there are 3 million or more in this country. it's most patients with cancers, and quite a lot of infections. 0ur genome contains the instructions for how our bodies work. errors in the dna code can trigger disease. six out of ten cancer patients who have genome analysis can benefit from targeted treatment — drugs which attack dna faults in their tumours. this can spare them the more toxic side—effects of chemotherapy. it costs £680 to scan a genome, and that price is falling every few months. in some cases, it's now cheaper than existing tests, like invasive biopsies. but what about data confidentiality? the nhs believes it can protect genomic information, but some are concerned about the safeguards. if you're going to take a lot of sensitive information from people, then you need to make sure that every use of it is consensual, that people have choices and can make choices, that it is handled safely, that you've got security, rules that are applied around who can access it. the more we learn about our dna, the greater the potential for new treatments and even cures. concerns over sharing data will need to be resolved if patients are to get the full benefits of the genome revolution. fergus walsh, bbc news. bbc news has spoken to a man in afghanistan who claims british special forces unlawfully killed members of his family. the bbc understand the royal military police are investigating the alleged incident back in 2011. the sunday times has alleged that members of the sas have killed unarmed afghan civilians and falsified mission reports to cover up the evidence. 0ur defence correspondent, jonathan beale reports. this report contains some flashing images. this is the war that many will remember from afghanistan. british troops in helmand fighting an insurgency. but what we didn't see were the secret raids that often took place at night involving british special forces such as the sas. there are now allegations that in some of these raids innocent civilians were killed. the bbc has interviewed one man, who's asked not to be identified, who claims unarmed members of his family were victims of one of those raids. translation: we were held blind—folded in a room overnight. early in the morning, the soldiers came back and said i should not go out until they had left. when their helicopters had gone, we came out and found they had shot my father, two brothers and a cousin. the bbc‘s been told the raid did involve special forces and is now being investigated. others who served in afghanistan have questions about the conduct of the sas, too. chris green was a reservist in helmand when he had to deal with the aftermath of another special forces raid in which locals allege civilians were killed in cold blood, one of a number of allegations first reported in the sunday times. it was my view that british forces and the ground holding troops that i worked with worked under very strict rules of engagement and it seemed to me that special forces did not. my own view of their accountability was i didn't see any, so when i sought information from them, this wall of secrecy was put in front of me. the ministry of defence says an investigation by the royal military police has so far found no evidence of criminal behaviour by british forces in afghanistan, with 90% of the allegations of abuse already dismissed. as to specific allegations against the sas, the mod has a long—held policy of never commenting on special forces. a former head of the army is urging caution. no witch—hunts, but no cover—ups. if there is evidence of wrongdoing, it should be investigated. but we should be very, very careful about throwing mud at our very special, special forces. allegations of widespread abuse by british troops in iraq have already been mostly discredited. that investigation is now closed. but there are still questions about their conduct in afghanistan and that might involve lifting the lid on the actions of britain's elite special forces. jonathan beale, bbc news. the latest round of talks to restore the northern ireland's power—sharing executive have ended without agreement. sinn fein has blamed the deadlock on the democratic unionist party's deal with theresa may to support the government in westminster. the dup says it wants to keep working on an agreement over the summer. northern ireland has been without a functioning devolved government since january because of a dispute between the political parties. the new director of the tate galleries has said she wants to make them much more accessible to the public and turn them into the most culturally diverse institution in the world. maria balshaw ran two successful museums in manchester before landing the job. she's the first woman to lead the tate in its 120—year history. 0ur arts editor will gompertz has been talking to her at london's tate modern. tate modern, the most visited museum of modern art in the world. it is the crown jewel in the tate empire built over the past three decades by sir nicolas serota who recently stood down as the institution's director. his replacement is maria balshaw, one of the forces behind manchester's recent cultural rennaissance and this institution's first female boss. it will be different because i am a different generation, i think differently from nick and some of those things are associated with my gender. certainly, after the announcement about my appointment i was approached by many, many younger women who i didn't know, who would just walk up to me at an opening and say, you're maria and ijust need to tell you it's very important that you have been appointed as director of tate. it makes that kind of thing seem possible for me. all i can observe is that it's not right that it's never happened before. we're on a journey that is around maintaining the tate sense of artistic adventure, its great scholarship and its knowledge and making sure that we are the most culturally inclusive institution in the world, that's where i want us to be. how far off are you from that? i think we are about a third of the way down the road. you said it's an absolutely accepted fact that 50% of the people in the uk don't care about art and think it's not for them. that's what will change. how? there will be a different proportion, will. that's the thing, i can't imagine, in fact, i don't think it would ever get to 100% of people, i am not convinced by 100% of anything. but i think we should absolutely reasonably expect that 75% of the population love the fact that we have a national collection, feel happy to be visiting tate and that every young person should be given an opportunity to think and play and experiment in the spaces that tate holds and that is a big, big shift. no collection is perfect and actually tate's collection in some areas is incredibly patchy. are there certain artists or movements or periods that you would like specifically to focus on? there are some important things that we'd like to address at the very beginning of the collection. there's no holbein here, so we would quite like to address that. a major frida kahlo would be a very important thing for the collection for the collection to have, given the other works that we have in the collection. the ambitious target to attract a more ethnicically and socially diverse range of visitors is clear. the collection agenda is bold. the challenge now is to realise those ambitions. will gompertz, bbc news. world champion road racer peter sagan has been kicked out of the tour de france, after an incident with the british rider mark cavendish. as the leaders approached the finish in vittel, sagan appeared to elbow cavendish into the barriers, sending him, and other cyclists, crashing to the ground. cavendish was taken to hospital before getting back on his bike and crossing the line to finish stage four. day two at wimbledon, and the top seeds in this year's draw have made it safely through to the next round. novak djokovic wasn't on court long — his opponent retired. but for many, today's star attraction was this year's favourite — seven—time winner roger federer. 0ur sports correspondent joe wilson reports. at 7.15pm they were leaving. an extra match had been quickly scheduled to extend the day on centre court. was it wozniacki you had come for? wasn't the plan. this is the love 30 era in men's singles. top four men's seeds at wimbledon this year all in their 30s. unexpected rest can come in handy. but we'd really like to know how novak djokovic is shaping up. trouble is, his opponent could barely move. djokovic took the first set 6—3 but early in the second martin klizan's calf could no longer support him. no surprise, he knew he was injured. so, sympathy but should he have entered the tournament in the first place? novak djokovic said he'd support a rule change in grand slams to try to encourage injured players not to come and still get paid. the early end for novak djokovic meant an early arrival for roger federer on centre and surely his match would last longer? well, it did, three minutes longer. at 35, he is fluid and forceful like only federer can be.
