welcome to bbc news, broadcasting to viewers in north america and around the globe. our top stories: kim jong—un announces the immediate suspension of north korea's nuclear and missile tests and closes down a test site. remembering columbine. thousands of american students walk out of classes on the anniversary of the high school massacre. the british prime minister theresa may promises compensation to long—settled immigrants from the caribbean who were unfairly threatened with deportation. the superstar swedish dj, avicii, dies at the age of 28, north korea has'a'nncxunced

and missile tests and a shutdown of its nuclear test site. the announcement comes ahead of planned summits with the leaders of south korea and the united states. president trump welcomed it as very good news, with the south koreans calling it a step forward in the denuclearisation of the korean peninsula. japan, however, has called on other countries to maintain pressure on north korea. bill hayton reports. in the six years he has been north korean leader, kim jong's nuclear missile programmes have made giant leaps. his regime is now thought to possess both a functioning nuclear weapon and the ability to hit parts of the united states. the region feared some kind of confrontation was coming, so this announcement appears to be good news. president trump certainly sees it that way. the diplomatic choreography leading to this point has been complex. kim jong—un visited beijing. mr trump's cia boss went to north korea. and the winter olympics allowed north korean officials to visit the south. the next step will be a meeting next

week between kim jong—un and his south korean counterpart. he has made his own gestures ahead of that encounter, calling for a peace treaty to formally end the korean war, and a new direct telephone line between the two leaderships was formally opened on friday. but not everyone is optimistic. despite a meeting between mr trump and japan's prime minister on thursday, the japanese government is cautious, saying this is not the time to ease pressure on north korea. but the fact that pyongyang is telling its people about the progress suggests it is serious about decreasing the tension on the korean peninsula. bill hayton, bbc news. and another assessment of the latest

statement. abraham denmark is former deputy secretary of defence for east asia under president obama, and now director of the asia program at the wilson center. it is a good sign that north korea is giving space for diplomacy, to move forward without interruption. but it isn't a major change. it is saying that north korea is going to freeze their testing and made no statement about a commitment towards denuclearisation or really any of the requirements that the trump administration has put forward as what they are looking for from this negotiation. so really, this is setting the stage for the summits that kim jong—un has coming up, as well as putting off an image that kim jong—un is a statesman, is ready to conduct diplomacy,

and is open to that discussion. and also, i mean, how — i mean, i'mjust asking how significant this is, but what can the sticking points be in the future, because i suspect there will be some things that need to be renegotiated and things which could, you know, pull these — pull the sides apart. well, this is an incredibly complex negotiation. it is a negotiation that has stymied administrations for decades. um, that north korea has, in the past, said it would denuclearise, said it would sign peace treaties with south korea, and all the while, it has continued to build these capabilities. so when president trump meets with kim jong—un soon, it is cutting the deal, figuring out how that deal is going to work will be very difficult and complex but even as difficult as that may be, the very difficult part, the real work starts after a deal is made, where the two sides need to figure out how to implement whatever agreement they come to, and how to verify that the other side is following through with those agreements, so this is incredibly difficult. it's stymied administrations in the past and it is unclear, one, if they can come

to an agreement and, two, if the agreement will hold up over time. it is it possible for denuclearisation to be conditional? in other words, for north korea to say "we will denuclearise if you can give us x"? sure, and that's usually how these negotiations go. in the past, north korea has stated that they would be willing to denuclearise as part of a broader nuclearisation of the korean peninsula, as they put it, which for them means an end to the us—south korea alliance, the removal of us protection, extended deterrence commitments to south korea, as well as other security assurances, including potentially the removal of us troops from the korean peninsula. in addition to signing peace treaties, diplomatic recognition, economic inducements — there's always a lot of concessions that have been attached to this and in the past, they have been concessions that have been either unacceptable or even when agreements were made and north korea did commit to denuclearise, they didn't actually follow through with that. friday marked the 19th anniversary

of the columbine shooting in the american state of colorado. in remembrance, students all over the us walked out of school demanding action on gun reform. one high school in atlanta wrote the names of shooting victims on sticky notes and placed them on the window of the school building. and in washington, several hundred students staged a vigil outside the white house before marching to the capitol. i am marching today because i believe adults have failed us. they are sending thoughts and prayers, but that will not do anything. you go to school and you are with your friends. you feel like something will happen. we are marching today to remind politicians this issue is not going away. some of my teachers are having asked practice for lockdown procedures more, but there is not much you can do about it. we are looking for a ban on semiautomatic rifles like the ar—15 and psychological evaluation on background checks. i do not think a teacher having a gun in a classroom

is even an option. i constantly lose the remote to my projector and they want me to be armed. it is not safe. let's take a look at some of the other stories making the news. the us democratic party has filed a lawsuit against russia, president trump's election campaign and wikileaks, accusing them of conspiring to shift the 2016 election in mr trump's favour. it claims his campaign, including two family members, in the party's words, gleefully accepted russian help to win the election. russia and the trump campaign have repeatedly denied collusion. the south african president, cyril ramaphosa, has appealed for calm after flying home from the commonwealth heads of government summit in london. he's trying to quell violent protests against the premier of north west province,

in the business, from madonna to coldplay, and tributes have poured in. rita ora, who he worked with, tweeted: . his music has been streamed more than 10 billion times online, and he hit number one spots around the world. he retired from touring in 2016, but continued to make music, saying his lifelong passion had come with a price. "i know i am blessed to be able to travel all around the world", he said at the time, "but i have too little left for the life of a real

the latest headline: north korea says it is suspending all nuclear and missile tests with immediate effect and closing its test site. all settled immigrants of the caribbean who have been treated u nfa i rly caribbean who have been treated unfairly will be compensated. the government has apologised after some children of immigrants who settled in the uk before the 1970s had been declared as being in the country illegally and threatened with deportation. they're known as the windrush generation after the ship that brought many to the uk in 19118. adina campbell has been speaking to some of those affected. file: injamaica, they couldn't find work. discouraged but full of hope, they sailed for britain. they were invited over to help rebuild britain after the war. their right to remain was supposed to be legally guaranteed. why have you come to england? to seek a job. how many have been detained as prisoners in their own country? can she tell the house...?

problems with paperwork have dominated politics all week. this is a day of national shame! theresa may has tonight confirmed that the government will make compensation payments. the uk government will do whatever it takes, including, where appropriate, payment of compensation to resolve the anxieties and problems which some of the windrush generation have suffered. if a human being wants to move from one place to another to feed their family... and some of them were here today in south london, along with campaigners to show their support. many felt action was long overdue. it's not good enough. sorry doesn't make it ok. sorry doesn't bring backjobs. sorry doesn't take away the pain and suffering that people have gone through. so sorry is not enough. those personally affected also shared their stories. i've never left the country, so i'm definitely suffering. but compensation would be really useful, you know, because we've suffered a lot of anxiety, of stress, you know, and right now, i just feel like i've

suffered so much. despite numerous apologies by the government and measures in place to tackle this issue, here, there still is very much a sense of anger and discontent and injustice. and one man still suffering is whitfield francis, who came to the uk from jamaica in the 1950s. unable to prove his legal status, he's been unemployed for the last four years and can't look after his family. i'm walking with a begging bowl, and i'm begging from my mother because she is a pensioner, and i'm begging from my sisters and begging from friends. after a while, as i said, you know, people get bored of it. for the first time, he is now calling a new government helpline for commonwealth citizens worried about their right to remain in the uk.

i've lived here since i was seven. the home office says it's changing its process to speed up these cases. so there we go, that's it. so it says your whole name, and it's until 202a. some have had their cases solved. michael braithwaite finally got the news he was hoping for. fantastic, you know? it has given me a sense of freedom. no more nightmares. but this is only the beginning. it is thought to tens of thousands of people could still be in limbo. adina campbell, bbc news. commonwealth leaders have agreed that prince charles will succeed his mother as the head of the organisation. james landale was in windsor to the leaders summit from where he sent this report. changing the guard at windsor castle.

only today, it wasn't just the soldiers. world leaders gathered beneath the battlements to decide who should replace their host as head of the commonwealth when her reign ends — a role that's never been hereditary. last night, the queen treated her guests and herself to a much—needed drink and gently reminded them she had a son who could take on the job when the time came. but today, she stepped back and gave them the run of her castle for their private deliberations without advisers or even a table. and they decided the prince of wales would, one day, be their next symbolic leader — a decision by consensus, according to one president, but by unanimity, according to the prime minister. his royal highness has been a proud supporter of the commonwealth for more than four decades and has spoken passionately about the organisation's unique diversity. and it is fitting that one day he will continue the work of his mother, her majesty the queen. and in a statement, prince charles said he was deeply touched and honoured by the decision.

but this summit wasn't just about agreeing the future leadership of the commonwealth, it was also about agreeing its future role. so, amid all the grandeur, the leaders also agreed plans to boost trade and cyber security, protect the world's oceans and support the international rules—based order. and zimbabwe's foreign minister was told by borisjohnson that britain would support his country rejoining the commonwealth if it embraces free and fair elections. so, a picture of the commonwealth's future is emerging. the task will be to keep it in focus. james landale, bbc news, at the commonwealth summit. a mexican court has barred sales of a controversial frida kahlo barbie doll, ruling that members of her family owned the sole rights to her image. the doll was launched in march, but provoked anger from some of kahlo's relatives who say the manufacturer mattel used her image without permission. the bbc‘s tim allman has more.

this isn't so much a home but a shrine to the artist frida kahlo. the walls are adorned with photographs of a woman now considered to be one of the great painters of the 20th century. for years, her relatives have insisted they own the rights to her image and her legacy. now a court in mexico seems to agree. translation: based on the documents that prove our rights, the judge ordered the company mattel in this specific case not to market the image of the brand frida kahlo. the frida kahlo barbie doll is part of mattel‘s inspiring women range, where the company says it celebrates female role models. she is described as an artist, activist, and feminist icon. but the family says the doll does

not represent the real frida kahlo. the skin tone is too light, for instance, her famous monobrow is missing. translation: i am really delighted because i believe thatjustice has been served. i think that what's yours will always be yours. this is a victory for the kahlo family, but it is only a first step — the court verdict applies in mexico and only mexico. her relatives say pending any appeal, they will launch a similar lawsuit in barbie's own country, the united states. tim allman, bbc news. arsene wenger is to leave arsenal at the end of the season, ending a near 22—year reign as manager. his decision to stand down brings to an end one of the longest tenures at the head of a top flight club. david ornstein reports.

cheering and applause. he was the man who brought glory to the gunners, transformed arsenal, revolutionised english football, established himself among the greats of the game. commentator: without defeat, without equal, without doubt, the best team in the land is arsenal. but in more recent years, arsene wenger has tasted a different side of the sport — intense criticism. all chant: we want wenger out! say we want wenger out! three fa cups in four years have failed to satisfy many arsenal supporters, their team no longer keeping pace with their biggest rivals, nor challenging for the biggest trophies, though even yesterday, the frenchman was underlining his commitment to the team. my personal situation is not so much my worry at the moment. you have to give me some credit. if you look back at my career, you would have to accept that my priority was always the interest of arsenal football club.

players and staff arrived at arsenal's training ground this morning unaware of what was about to unfold. the 68—year—old saying the decision followed careful consideration and that he was grateful having had the privilege to serve the club. it marks the end of an iconic era that saw wenger introduce new training methods, a thrilling style of play with plenty to show for it — three premier league titles, a record seven fa cups, and perhaps his greatest achievement, an entire league season unbeaten. was a dominating guy mid ‘90s, maybe early 2000 when he was really winning pretty much everything, played wonderful football, so i admired his work always. the subject of wenger‘s future has long divided arsenal fans, yet today they were united. a couple of cup wins have been glossed over the cracks but i think it's the right time. i'm very sad that he's going. i wonder who we are going to get next.

so the speculation which has come to engulf this club and its manager is finally put to rest. however, that only makes way for even greater uncertainty at arsenal — that of life without wenger. david ornstein reporting. earlier this week, we told you all about the boston marathon, where competitors faced driving wind and rain. well, that certainly won't be a problem here in london this weekend where temperatures have soared and could be the hottest on record for the race. joe wilson has more on the build—up to this weekend's run. this is the same mo farah. what's different is the distance and the scenery. on the track, he beat everyone, everywhere, but moving to the marathon — 26 miles, 35 years old — he warns us to be realistic. the best runners do turn up here, so sunday's race is going to be a difficult one. i'm ranked number 27, so we'll see. but the thing is, mo, knowing you... yeah. ..you're not going to have gone on this marathon journey without thinking it's going to end in glory. no...

i mean, it has to end in tokyo with a gold medal, doesn't it? no, it's possible, and my aim is to be able to run as many marathons as i can, to learn about them, and to run decent times. mo farah should not be bothered by london heat, having prepared in ethiopia. he's ended his association with alberto salazar, a controversialfigure, and is now coached by gary lough, husband and former coach of paula radcliffe, who sees farah's prospects this way. it's a big ask for someone who is world class at 1,500 metres, best in the world at 5,000 and 10,000 metres, to then come in and dominate at the marathon. that's not going to happen. but he can be competitive, and it depends how the race pans out. but for the masses, the heat will be a challenge. this year, think carefully before wearing fancy dress, the organisers advise. but the marathon will always push runners to the limit. that is the point. remember this from last year? david wyeth helped to the finish line by matthew rees — two strangers united. and they are back this year, urging competitors to be sensible. got to pay attention to the weather,

got to rein in the pace. you know, maybe this year isn't the one for a pb, but it's certainly going to one to be enjoyed. and you're not going to be stopping for this guy this year, no? um, well, i hope not! we'll both run our own race and we'll see each other at the end. yeah, matt is a great runner and, um, he's even more inspired these days to get out in front and stay in front — don't cross paths with me! the pose, mo, well, there we are. this man has perfected winning, yes, but the finishing line is now a marathon away. joe wilson, bbc news, tower bridge. just a reminder that you can get in touch with me and most of the team on twitter. i tweet occasionally some interesting stuff but i will try harder to do it more now. i'm @nkem|fejika. hello again. it was another glorious day of weather yesterday, wasn't it?

for most of us, we had the sunshine, and the hot spot was in kent, 27 degrees celsius recorded underneath skies like these. and just as we were getting used to all that heat, it looks like temperatures are going to come crashing down as we look at the forecast into next week. so take a look at london this weekend — about 26 celsius. we'll come down to about 17 degrees on monday, the weather turning much more unsettled as well. before we get there, a few mist patches to watch out for this morning. quite chilly air in the north. not too cold further south. and this is what the weather has got in store for us this weekend. we'll all see spells of warm sunshine but temperatures will be easing through the weekend and we will start to see thunderstorms breaking out. now, the initial batch of storms will be with us this afternoon and will continue to rumble away as we head through the this evening and overnight as well. so, here's the forecast. a dry start to the day for most of us. a few mist patches towards south—east england, around the chilterns, there are a few for sussex and kent as well, but these should tend will clear away. most of us will then

get some sunny spells. it will feel warm in the sunshine as well with temperatures climbing to 26 degrees towards south—east england but we will start to see showers developing later in the day. now, initially, the showers might not have too much in the way of heavy rain, but big raindrops. but later on, as those showers continue to move in across parts of eastern england, maybe the midlands too, well, the showers will turn increasingly heavy with a greater risk of thunder overnight. so there are those thunderstorms, clearing the way eastwards through saturday night. temperature wise, still into double figures for much of inland wales, we've still got that slightly cooler air further north for scotland and for northern ireland as well. further changes in the weather picture as we head through sunday. this cold front is going to be sweeping its way eastwards and it is this that will be bringing a cooler, fresher feel to the weather across north—western areas. outbreaks of rain to start the day as well in scotland and northern ireland, swinging eastwards. and as our cold front reaches parts of east anglia, south—east england, it will tend to turn more showery,

so there could be further heavy, thundery showers dotted along as that front moves through. a cooler, fresher feel to the weather for the north—west. temperatures 22—23 degrees across parts of eastern england but, of course, that will make it pretty uncomfortable for the runners running the london marathon. it will get quite warm with temperatures pushing on into the low 20s for the finishers during the afternoon. it will turn cooler, then, as we head towards next week. instead of southerly winds, we've got the winds coming in from the atlantic, bringing a significant drop in temperatures. and the weather will turn quite unsettled across the north—west with rain at times as well. that's your latest weather. have a great weekend.

this is bbc news — the headlines: north korea has announced the immediate suspension of nuclear and missile tests, saying it had completed the weaponising of nuclear arms. state media said the suspension was aimed at pursuing economic growth and peace on the korean peninsula. relations between the two koreas have thawed recently. theresa may has said members of the so—called windrush generation who have been treated unfairly by the home office will be given compensation. her comments came after it emerged that some people who came to the uk from the caribbean before 1971, have had their immigration status wrongly challenged. one of the world's biggest dance music stars, the swedish dj avicii, has died in oman at the age of 28. avicii, whose real name was tim bergling, stopped touring in 2016 because of ill health, in 2016 because of ill health.
