this is bbc news, i'm nkem ifejika. our top stories: kim jong—un announces the immediate suspension of north korea's nuclear and missile tests remembering columbine — thousands of american students walk out of classes on the anniversary of the high school massacre. the british prime minister promises compensation to long—settled immigrants from the caribbean who were unfairly threatened with deportation. # so wake me up when it's all over. ..# the superstar swedish dj avicii dies at the age of 28 — tributes pour in from the pop world. welcome to bbc news. north korea has announced the immediate suspension of nuclear and missile tests and a shutdown of its nuclear test site. kim jong—un said further tests

were unnecessary because nuclear weaponisation had been achieved. 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 de—nuclearisation 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—un‘s nuclear and 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. and his south korean counterpart moon jae—in. 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. abraham denmark is former deputy secretary of defence

for east asia under president obama and now director of the asia programme at the wilson centre. he gave me his assessment of the latest statement from pyongyang. it is a good sign, that north korea is giving space for diplomacy to move forward without interruption. but it's not a major change. they say they are going to freeze their testing, they made no statement about a commitment to denuclearisation or any of the requirements that the trump administration has put forward in what they are looking for in this negotiation. so, really, this is setting the stage for the summit kim jong—un has coming up, as well as putting out an image that kimjong—un is a statesman and is ready to conduct diplomacy and is open to that discussion. and also, i mean, i havejust asked you how significant this is, but what could the sticking point be in the future? because i suspect there will be some things

which need to be negotiated, some things which could pull the sides apart. this is incredibly complex, this negotiation. it is a negotiation which has stymied administrations for decades. north korea has in the past said that it will denuclearise, it has said it will sign a peace treaty with south korea, and all the while it has continued to build these capabilities. so when trump meets with kim, it is about cutting that deal, figuring out how it is going to work. it will be difficult and complex. but the very difficult part, the real work, that will begin after the deal is made. two sides will need to figure out how to implement what they are going to come to, and how to verify that the other side is following through on that agreement. so this is incredibly difficult. it has stymied administrations in the past. it is unclear if they will be able to come to an agreement, and unclear whether that agreement will hold up

over time. 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?" yes, and that is generally how these negotiations go. in the past north korea has said they would be willing to denuclearise as part of a broader denuclearisation of the korean peninsula, which for them means an end to the american and south korean alliance, the removal of us protection 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 are lots of concessions which have been attached to this, and in the past there have been concessions which have been either unacceptable or even when they have remained, when they said they would denuclearise,

they did not follow through. let's take a look at some of the other stories making the news. republicans in united states have dismissed as frivolous a lawsuit brought against the republican party, the trump campaign and wikileaks. accusing them of conspiring to shift the 2016 election in mr trump's favour. 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, and went straight into marathon talks with local members of the governing african national congress. crowds first took to the streets on wednesday, to demand the resignation of the provincial premier amid accusations of corruption. i want to assure everyone

we are going to act speedily on this matter. we cannot give an exact timeframe now, but we are going to act as speedily as possible to address each of the issues that have been raised with us. 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. 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 are just like, i love you, and i just want to make sure you know that in case something happens. we are marching today especially to remind politicians that we aren't forgetting that this issue isn't going away. some of my teachers are having us practice for lockdown drills 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. the federal aviation administration in the united states has ordered emergency inspections of aircraft

engines similar to the one that ruptured during a recent southwest airlines flight, leaving one passenger dead. the left engine of the southwest airlines flight suddenly blew apart during a flight from new york to dallas on tuesday. a first inspection of the boeing 737‘s damaged engine showed that an engine fan blade was missing, apparently broken due to metalfatigue. britain's prime minister says long—settled immigrants from the 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 1948. 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.

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, 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, i'm begging 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

in difficulties during labour and conditions such as pre—eclampsia. and children are six times more likely to develop type 2 diabetes if the mother has the condition. the bbc‘s tulip mazumdar has been finding out more. they're exploring an exciting underwater world, while their mums get a bit of exercise in the pool. gestational diabetes is affecting an increasing number of women, but there's not much awareness about the condition. i think it's linked to the sugar that you eat. i knew about diabetes, but not really in pregnancy. it's when women develop high blood sugar levels during pregnancy. anyone can develop the condition, but women are at higher risk if they are obese or from certain ethnic backgrounds. i'm considered high risk. i'm from a south asian background, i have a family history of type two diabetes. i'm not overweight, but i do have a very sweet tooth.

my blood sugar levels are normal for now, but for many women finding out that they do have gestation diabetes, this can be a very anxious time. the babies can grow bigger than average, which can cause problems for mum and baby at the time of birth. sometimes it can increase the risk of developing a condition called pre—eclampsia, and we know that there's a slightly higher chance of having a stillbirth. many affected women, like this woman here at guy's and st thomas' hospital in london, are on daily medication and have to have finger prick tests several times a day. 50% go on to develop type two diabetes. researchers here are also looking into weather the condition changes the dna in the fetus, increasing the likelihood of the baby becoming obese in later life. —— whether the

condition. we have an epidemic of gestation or diabetes, and that is because obesity is on the rise. —— gestational. what we would really like to do is say at the beginning of pregnancy, when a woman comes to her first appointment, we could do a simple test and say you are very likely to get gestational diabetes and then to institute treatment early. for some women the diagnosis has been a wake—up call. this is like a warning for some women. get control of these things so you don't get type two diabetes. you can be more empowered and take charge of your diet and lifestyle. that is something i will definitely be doing. we all want to have a safe pregnancy and a happy, healthy baby at the end of it. results from the latest research looking into the long—term impact of this condition is due out later this year. tulip mazumdar, 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. 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. at 48 years old, actress rachel weisz has announced that she is expecting a baby with her husband daniel craig. the oscar—winner has an 11—year—old son, while bond star craig, 50, has a 25—year—old daughter. in an interview with the new york times,weisz said: "i'll be showing soon. daniel and i are so happy." weisz and craig have been together for eight years and married in new york in 2011.

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 some 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 for england and 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. 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.
