this is bbc news. i'm duncan golestani. our top stories: kim jong—un announces the immediate suspension of north korea's nuclear and missile tests. the american democratic party sues the russian government, wikileaks and the trump campaign for conspiring to steal the 2016 election. the superstar swedish dj avicii dies at the age of 28 — tributes pour in from the pop world. and after 22 years at the top of english football — arsenal manager arsene wenger says he's stepping down. hello and welcome to bbc news.

we start with news breaking in the last couple of hours — because north korean state media is reporting that the country's leader, kim jong—un, has suspended nuclear and missile tests with immediate effect. it's also been reported that he will shut down a nuclear test site. relations between the two koreas have thawed in recent weeks. president trump has already tweeted his response, saying: "north korea has agreed to suspend all nuclear tests and close up a major test site. this is very good news for north korea and the world — big progress! look forward to our summit." ankit panda is a senior editor at the diplomat foreign affairs magazine. he gave us his view from new york. north korea has conducted six nuclear tests and there is good reason to believe they are happy with what they have accomplished.

the statement released by the korean central news agency suggest that, north korea is not ceasing nuclear testing out of an act of altruism, but because it has the weapons that it thinks it needs in the future to deter the united states and south korea from a potential invasion or attack. so i think they are quite happy with their arsenal, and they would be testing any more nuclear weapons. they are happy with their arsenal as you quite memorably put it but intercontinental ballistic missile is would go through much more testing than this, if we look at the history of how countries have developed their nuclear weapons, so this does seem to be quite a premature stopping of the testing, doesn't it? that is right, we should recall that north korea has submitted to unilateral moratoriums on the stick missile testing before, in1999, on the stick missile testing before, ini999, and in on the stick missile testing before, in 1999, and in 2006 it broke that moratorium. if i were north korea i

would want to test my icbms more, a dude nittis these missal is that they have generated to their full range in the future. —— they do need to test these missiles. but they... they will potentially test these measures in the future. verifying this agreement from north korea will be quite important. as with all these things come at the devil is really in the detail. do you think we should not be getting too carried away, you mentioned the 90s, we are in the madeline albright go into north korea to bill clinton, the great hopes then. every president since have a moment of hope with north korea. should we keep this in check, do you think, until we actually see some results?” certainly think we should not let the perfect become the enemy of the good. one lot of north korea has said today it can lead to agreements. if we can keep the

number of nuclear tests in the 20th -- zist number of nuclear tests in the 20th —— 21st century to six, all of which have been carried out by north korea, that is a positive development. there is room here for north korea to go back on its word and the summit with president trump isa and the summit with president trump is a report —— an important reward in itself, which is why they are making these concessions upfront. they want to make sure president trump has no reason to go back on that summit. 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, gleefully accepted russian help to win the election. russia and the trump campaign have repeatedly denied colluding. our correspondent chris buckler is in washington — he emphasised that there are already several investigations looking in to the alleged russian meddling. there are a lot of investigation is

taking place, not least the special counsel investigation being headed by robert mueller, looking into these allegations of collusion and questions of russian meddling in the 2016 presidential election. but this is something different. and from the point of view of people in washington there are some who will say that this is the democrats right to basically take a lawsuit to try and say, look what was done in their selection. on the other hand they will be others that regard this as a publicity stunt. if it is a publicity stunt. if it is a publicity stunt, it hits all the right targets. if you look at this, it includes donald trump's sun, it includes his campaign manager, it has his son—in—law. those individuals were involved in that

trump tower meeting in the summer of 2016, allegedly meeting individuals with russian connections. so from the point of view of there being a lot of talk around collusion, a lot of claims about what part russia played in the 2016 presidential election in the us, certainly what we have seen here is from donald trump's point of view and the republican point of view, a lot of muckraking. but the democratic party say they have a right to do this and they intend to take this suit. this does cap off quite a terrible week for donald trump because he has been putting up with headlines every day from his former fbi‘s book to, so presumably this is just going to rile him even further? yeah. if you look at his twitter feed where you get his thoughts, donald trump continues to be buoyant in his response to a lot of this, saying that they was no collusion, and the mueller investigation is a

witch—hunt, attacking the former fbi james comey, who he fired and his look puts out a whole bunch of allegations, and just 2a hours ago we got comey‘s memos of meetings held with donald trump in trump tower and the oval office. but when you look at this it is all focusing on the same issue, and it is frustrating to donald trump, it is frustrating to donald trump, it is frustrating to donald trump, it is frustrating to those around him, that there is this cloud that continues to hang over his presidency. these questions of this investigation, that robert mueller is leading, and certainly this plays into it, by claiming that they are or some kind of conspiracy between the trump campaign, wikileaks, and the trump campaign, wikileaks, and the russian government. as i say, they will continue to deny that, i don't think that when you look at this particular legal suit, there is really a ny this particular legal suit, there is really any sense of new information coming out, but wanted does is it keeps it in the public domain.

another thing worth mentioning is that there are some who feel that this legal suit may not go far, particularly when it comes to russia asa particularly when it comes to russia as a sovereign country, it is generally immune to this kind of suit. one of the world's biggest electronic dance music stars, swedish dj avicii, has died in oman at the age of 28. he was best known for his million selling uk number one single "wake me up". avicii had retired from touring in 2016 due to health problems. here's andrew plant. #so # so wake me up when it's all over. . . the # so wake me up when it's all over... the dance music dj avicii, whose club anthems made him famous worldwide, accurate to began making music in his bedroom in sweden, for his talent caught hold, taking him ona his talent caught hold, taking him on a ten year career that saw him filling hundreds of venues with thousands of fans. there are very few genuine megastars from my world,

and avicii was one of the handful of them, with a really distinctive melodic sound, a classicjourney up from the underground through to the extreme mainstream, and very much responsible for the breaking actually of dance music in the one territory where it simply could not get a foothold prior to avicii's success , get a foothold prior to avicii's success, and that is north america. avicii worked with some of the biggest names 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 tearing in 2016, but continued to make music, saying his lifelong passion had come with a price. "i knowi saying his lifelong passion had come with a price. "i know i am blessed to be able to travel all around the wo rld " , to be able to travel all around the world", he said at the time, but i have two little left for the life of a real person behind the artist." his latest collection was nominated for a billboard music award just a few days before his death. tim bergling, otherwise known as avicii, who has died at the age of 28. let's take a look at some of the other stories making the news: officials in gaza say that two palestinian men have been shot dead by israeli forces during the fourth consecutive friday of mass protests on the border with israel. 36 palestinians have been killed by the israeli army since the demonstrations began. a british teenager who leaked sensitive documents from senior fbi and cia staff has been jailed for two years.

kane gamble, who was 15 and 16 at the time, targeted high profile figures such as the cia chief and fbi deputy director from a computer at his family home. his defence said he was "naive", but the judge said gamble ran a "campaign of cyber terrorism". nine parts of the english city of salisbury have been sealed off , with government scientists warning there could still be toxic "hotspots" after last month's nerve agent attack. the sites are to be decontaminated as a result of the poisoning of the former russian spy, sergei skripal, and his daughter. officials have insisted that the city is safe for the public. daniel sandford reports. almost seven weeks on from the salisbury poisoning, the city is still sprinkled with no—go areas — cordoned—off zones, where scientists fear there could still be hotspots of the deadly novichok nerve agent. the nine zones include

detective sergeant nick bailey's home, the central police station and sergei skripal‘s house, as well as the pub, restaurant and park where the skripals went after becoming contaminated. and at the nine sites this week, the cordons, instead of being removed, are being strengthened and reinforced, as salisbury prepares for a clean—up that could last months. the man leading the city's recovery told me why it's taking so long. every site will be sampled, cleaned, tested. if there's any trace remaining, it will be cleaned again. even to the point of removing soil and in brickwork, if necessary. but the russians have another explanation for the salisbury decontamination. we get the impression that the british government is deliberately pursuing a policy of destroying all possible evidence, clarifying all the remaining materials and making an independent and transparent investigation impossible. when the prime minister came

to salisbury five weeks ago — promising to get the city back on its feet — the first place she visited was dinghams cookshop. but today, becca hardingham, who runs the shop, says takings are still down. well, we were hoping it wasjust going to be a few weeks and we'd be able to just go past it and get on with life but, yeah, it's been a struggle. it feels frustrating. business is struggling and we're just a bit worried that salisbury‘s just going to die from it. this week, the first pictures emerged in russia of yulia skripal leaving moscow airport on the day before the attack. friends have now confirmed that it is her. she left hospital 11 days ago, and while her father is still an impatient, his health is improving and he too could be discharged soon. stay with us on bbc news, still to come: with record

temperatures forecast, organisers of the london marathon tell fundraisers to ditch the fancy dress. the stars and stripes at half—mast outside columbine high, the school sealed off and the bodies of the dead still inside. i never thought that they would actually go through with it. some places and have already had nearly as much rain as they'd normally expect in an entire year. for millions of americans, the death of richard nixon in a new york hospital has meant conflicting emotions. a national day of mourning next wednesday sitting somehow uneasily with the abiding memories of the shame of watergate. and lift—off of the space shuttle

discovery with the hubble space telescope, our window on the universe. this is bbc news. the latest headlines: north korea says it is suspending all nuclear and missile tests with immediate effect. the british prime minister theresa may, has said that caribbean migrants who've been treated unfairly by uk immigration authorities will be compensated. speaking at the close of the commonwealth heads of government summit in south—west england, she said she was committed to resolving cases where members of the so—called windrush generation had been wrongly targeted. adina campbell has been speaking to some of those affected. injamaica, they couldn't find work. —— 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 now confirmed that the government will 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 is still 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 and unemployed for the last four years, he 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.

queen elizabeth, as the head of the organisation. the decision was confirmed in a statement by leaders at the end of the summit in the uk. our diplomatic correspondent james landale was in windsor for the summit. 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. the english premier league's

longest serving manager, arsene wenger, has announced that he's to leave arsenal at the end of the season after 22 years in the job. david ornstein has the details. he was the man who brought glory to the gunners. transformed arsenal, revolutionised english football, established himself among the greats of the game. without defeat, without equal, without doubt, the best team in the land is arsenal. but in more recent yea rs, in the land is arsenal. but in more recent years, arsene wenger has tasted a different side of the sport, intense criticism. three fa cups infour sport, intense criticism. three fa cups in four years have failed to satisfy many arsenal supporters of their team no longer keeping pace with their biggest rivals, more challenging to 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 a lwa ys 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 he was grateful to have the privilege to serve the club. it marks the end of an iconic irreverence all arsene wenger introduce new training methods, a thrilling style of play with plenty to show for it, three premier league titles, a record seven fa cup, and perhaps his greatest achievement, an entire league season unbeaten. dominating guy in the mid— 90s may be early 2000 when he was really winning pretty much everything,

playing wonderful full all, so winning pretty much everything, playing wonderfulfull all, so i admired his work always. the subject of arsene wenger‘s future has long divided arsenalfans of arsene wenger‘s future has long divided arsenal fans it today they we re divided arsenal fans it today they were united. a couple of wins have been glossed over the cracks but i think it is the right time. i'm very sad that he is 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 it only makes wafer even greater uncertainty at arsenal, that of life without arsene wenger. earlier this week, marathon runners in boston faced driving wind and rain. well, that certainly won't be a problem in london this weekend, where temperatures have soared. 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, you're not going to have gone on this marathon journey without thinking it's going to end in glory. it has to end in tokyo with a gold medal, doesn't it? no, it is possible and my aim is 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, the 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. the london marathon is a mass display of stamina and eccentricity. 26 miles is nothing unless you do it as a rhino, ora pillar box, ora...that.

but be careful, organisers warn. if it's 20s degrees on sunday, should you really run in a fake fur coat? it's hard enough in a vest. 12 months ago, david wyeth was led and cajoled to the finish by matthew rees — two strangers united. and they're back this year, urging competitors to be sensible. you've got to pay attention to the weather. you have to rein in the pace. maybe this year isn't the one for a pb, but it's certainly one to be enjoyed. and you're not going to be stopping for this guy this year, no? well, i hope not. we'll both run our own race and see each other at the end. matt is a great runner and 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. stay with us here on bbc world news. 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, with 27 recorded underneath skies like these. just as we were getting used to that heat, it looks like temperatures are going to come crashing down as we look at the forecast for next week. london this weekend, about 26 celsius, coming down to 17 on monday. turning more unsettled as well. a few patches of mist to watch out for this morning. chilly air in the north. not too cold further south. this is what the weather has in store for the weekend. we will 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 evening and overnight as well. so here's the forecast. a dry start for most of us. a few patches of mist in south—east england,

around the chilterns and some for sussex and kent, but these will clear away. most of us will then get some sunny spells. warm in the sunshine as well with temperatures climbing to 26 degrees in south—east england. we will start to see showers developing later in the day. initially, they might not have too much in the way of heavy rain, but big raindrops. later, as those showers continue to move in across parts of south—east england and maybe the midlands as well, the showers will turn increasingly heavy, with a larger risk of thunder overnight. there are those thunderstorms, clearing the way eastwards across saturday night. still into double figures for much of inland wales. slightly cooler air further north for scotland and northern ireland. this cold front is going to be sweeping east and it is this that will be bringing a cooler and fresher feel to the weather across northern and western areas. outbreaks of rain to start the day in scotland and northern ireland, swinging east. as the cold front reaches parts of east anglia and south—east england, it will turn more showery. there could be further heavy and thundery showers dotted along

as that front moves through. a cooler and fresher feel to the weather for the north—west. temperatures 22—23 for parts of eastern england but that will make it pretty uncomfortable for the runners running the london marathon. it will get quite a bit warmer, temperatures pushing on into the high 20s as the race finishes in the afternoon. it will turn cooler as we head into next week. because of that system of southerly winds, we have the winds coming in from the atlantic, bringing a significant drop in temperatures. the weather will turn quite unsettled across the north—west with rain at times as well. that's your latest weather. have a good 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. the us democratic party has filed a lawsuit against the russian

government, president trump's election campaign and the website wikilea ks, accusing them of conspiring to influence the 2016 american election. russia and trump campaign officials have repeatedly denied allegations of collusion. 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, including acute pancreatitis. now on bbc news, click.
