welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is duncan golestani. our top stories: separatist clashes flare up in yemen, raising concerns that the country's fragile humanitarian situation will become worse. a day of mourning in kabul — more than 100 people are now known to have died in saturday's suicide bombing. russia's opposition leader, alexei navalny, is released after he and dozens more are arrested at a protest rally, in moscow. and the grammys are under way in new york. attendees wear white roses in solidarity with victims of sexual harassment. aid groups say new fighting in southern yemen has made

an already bad humanitarian situation worse. at least ten people were killed and dozens of others injured in the port city of aden, on sunday, during fighting between former allies in the civil war. the yemeni president abdrabbuh mansour hadi, who's based in saudi arabia, has ordered an immediate ceasefire. bill hayton reports. this is a war within a war. the southern city of aden a battlefield between factions who once fought together against the houthi rebel movement. the former allies are now divided over the future of the country. these men are waving the flag of the former south yemen, a country that ceased to exist nearly 30 years ago, when it merged with north yemen. now, some want it to split again. translation: we want

a civilian government, a government of law, a government made according to the principles of the southern transition proposal. these southern separatists are a faction backed by the united arab emirates. they want the government to resign. the internationally recognised government is backed by saudi arabia, and refuses to go. the two now have managed to agree a truce. translation: we are asking all fighters to come back and improve our defence, and provide a real administration, that assures everyone justice and equality. yemen is already divided between government and rebels. these secessionists want another division, back to the old north—south border. it is not clear how much support they have. in aden, the fighting seems to have subsided. but the tensions remain, and the peace may not last long. we have some breaking news now:

suspected militants have launched an attack on a military training academy in the afghan capital, kabul. an eyewitness said explosions hit an area near the marshal fahim national defence university, west of kabul city—centre. the explosions began at around 5 o'clock local time and lasted for at least an hour. small arms fire was also heard. fighting between attackers and security forces at the site is said to be continuing. the complex has been targeted before: 15 cadets were killed in a suicide bombing last october. we'll bring you more on that as we get it. more than 100 people are now confirmed to have been killed, and 230 injured, in saturday's suicide bombing in kabul. the country has been observing a day of national mourning after one of the worst attacks in years. from kabul, secunder

kermani sent this report. hospitals across kabul have been at full stretch, trying to treat the huge number of wounded. this taxi driver was just metres away from the explosion. translation: there was smoke, shrapnel, and burning smell everywhere. everyone looked terrified. there were dead bodies and injured people covering the street. the taliban packed this ambulance with explosives. the attacker detonated them close to a police compound on a busy street. over the last year, kabul has been repeatedly attacked. it used to be one of the safest places in the country. now, it feels like one of the most dangerous. the taliban and the islamic state group both, at the moment, seem to be focusing their efforts on targeting the capital, kabul, rather than trying to capture rural territory from the security forces. they know that attacks here will spread fear,

will generate headlines, and will undermine the government. i asked the head of the afghan intelligence service about rising public anger with his forces' failure to prevent so many attacks. we are using all our assets, all our our — whatever possibility and resources in our hand to prevent it. but you cannot prevent 100% of the attacks. meanwhile, the families of victims line up outside hospitals, desperate for news. this man has been going from morgue to morgue, trying to identify his cousin's corpse. translation: i've seen so many dead bodies. all the morgues are full of them. they're all burned so badly, you can't even recognise them. last year, more than 2,000 civilians were killed injust nine months across afghanistan. this year looks set to be just as deadly.

secunder kermani, bbc news, kabul. thousands of people have demonstrated in cities across russia in support of calls by the opposition leader, alexei navalny, for a boycott of the presidential election in march. police in moscow detained mr navalny as he took part in a rally in the city centre. he's now been released without charge. the bbc‘s steve rosenberg was at the protests and witnessed mr navalny‘s arrest. it isn't easy taking on the kremlin. alexei navalny has been jailed three times in the last year. he has been barred from the upcoming presidential election. so today, mr navalny called his supporters onto the streets. alexei navalny is russia's most prominent opposition figure, and president putin's most vocal critic. he has been barred from running in the presidential election. he is now being arrested by police.

this was no "softly, softly." we saw mr navalny surrounded by police. seconds later, he was thrown onto the ground. then, the politician vladimir putin cannot bring himself to mention by name was dragged into the police bus. his supporters called on voters to boycott the election. all the candidates, they believe, are hand—picked by the kremlin. they are candidates that putin approved, and we do not have candidates that we want to have. there is little doubt that vladimir putin will walk this election, with the help of russian tv, which maintains his macho image, portraying him as a cross between action man and father of the nation. and mr putin enjoys far more airtime than any of the other candidates. but the kremlin still

needs people to come out and vote for vladimir putin. that is why calls to boycott the elections are making the russian authorities nervous. steve rosenberg, bbc news, moscow. it was very much bruno mars's night that the grammys. let's cross live to new york — where we can speak to the bbc‘s nada tawfik. quite a few political moment up on stage? absolutely. i think in music,

a lot of the artists discuss the social issues through their song but we saw the date in performances and the red carpet the #me too looked at. white roses were born in solidarity with victims of sexual abuse. kesha gave a powerful performance, one i think will be talked about by a long time. she was joined by cyndi lauper, julia michaels and other female artists who sang in the chorus as she sang her song, praying. we had a diverse group of artists such as kendrick lamar, opening up the grammys at singing an array of his track from his album, damn. and that was an

album that spoke about racial issues, political issues in this country and so he had performances by you to and dave chappel as well that spoke about those themes and then we also had a little comedy sketch where several of the performance read excerpts of the book by an fury and hillary clinton made a cameo, reading a portion of that book. president trump was angry at that. he slams the book, i look at that. he slams the book, i look at the inside workings of his white house. ajab at the inside workings of his white house. a jab at the president at the grammys as well. hillary clinton appearing was one of those moments, wasn't it. in times of the winners, did do is predict that? you know, a lot of people expected jay z or kendrick lamar to win for album of the year but bruno mars beat them

out. jay z led the nominations of with eight going into the grammys but he did not take those prizes and i think that was a bit industry. kendrick lamar didn't do quite well, with five grammys, including best wrap performance, best wrap album. —— rap, and that is quelled some of the criticism about the grammys have received about not giving enough recognition of the role rap has played in the music industry and culture. ed sheeran was expected to win best pop solo performance just because he was shut out of some of those other top categories. a little bit of unexpected but some surprises in there. let's take a look at some of the other stories making the news: prosecutors in cambodia have charged

ten foreigners with producing pornographic images, after raiding a villa in the north—western town of siem reap. they were arrested on thursday after images emerged of people apparently imitating sexual positions at a party. but some reports say several people in the pictures from the party do not appear among those held. the polish president, andrzej duda, says he will review a draft bill which would make it illegal to refer to nazi death camps as polish. israel has fiercely objected to the proposed legislation, saying it would prevent the truth being spoken about the holocaust. poland argues that the second world war death camps were operated entirely by occupying german forces. greek cypriots will need to vote again after an inconclusive result in the first round of their presidential election. with all votes counted, the current conservative president, nicos anastasiades, garnered the most votes, but not enough to avoid a run—off in a week's time. he will face the leftist

candidate, stavros mala. there's been an outcry in mexico city over the disappearance of a teenage student who was arrested by police on tuesday. hundreds of people carrying placards called for the return of 17—year—old marco antonio sanchez. he had been out taking photographs but was arrested and accused of stealing the camera. the bbc‘s tim allman reports. "where is marco? " the question being asked by his family and friends. a teenager described as playful, a joker, very good—natured, who's been missing for a week now. he was last seen being bundled into a police van after being accused of stealing a camera. his family are desperate for answers. translation: the way my nephew was arrested,

and the brutal way he was beaten, that he did not arrive where he was going to, to blame him for that or accuse him of something he wasn't doing. this isn't the first time a young person has mysteriously disappeared, nor is it the first time the police are being blamed. officers in several mexican states have been accused of abuse, torture, and extorting money from students and their families. is marco sanchez the latest victim of deadly police corruption? translation: where is he? people do notjust disappear. that's a lie. they took him. the immense pain that this means for families, for all of us, for those of us who have children in this city, who are growing up here, who has the ultimate responsibility? who allows this exercise of corruption, impunity, violence? two officers involved in marco's

arrest have been detained, but the fate of marco antonio sanchez remains a mystery. tim allman, bbc news. stay with us on bbc news, still to come: tributes to the father of flat pack furniture and founder of ikea who's died at the age of 91 the shuttle challenger exploded soon after lift—off. there were seven astronauts on board, one of them a woman school teacher. all of them are believed to have been killed. by the evening, tahrir square, the heart of official cairo, was in the hands of the demonstrators. they were using the word "revolution". the earthquake singled out buildings and brought them down in seconds. tonight, the search for any

survivors has an increasing desperation about it as the hours pass. the new government is firmly in control of the entire republic of uganda. moscow got its first taste of western fast food as mcdonald's opened their biggest restaurant in pushkin square. but the hundreds of muscovites queued up today will not find it cheap, with a big mac costing half a day's wages for the average russian. this is bbc news. the latest headlines: aid groups in yemen say new fighting in the port city of aden has made an already bad humanitarian situation worse. at least ten people died in fighting on sunday. there is new doubt surrounding the security of so—called

cryptocurrency exchanges, which handle digital cash systems like bitcoin. 0ne ofjapan‘s biggest exchanges, coincheck, has offered to refund $500 million in currency stolen by hackers on friday. japan is one of the world's most enthusiastic traders in cryptocurrencies. this report by rhodri davies contains flash photography. as many as 10,000 businesses injapan are said to accept cryptocurrencies. this virtual heist is bound to increase concerns about their security. at the centre of this, tokyo—based coincheck, one of the largest digital currency exchanges injapan. it said on friday it had been hacked, resulting in the loss of $500 million — the biggest ever. translation: there are some troubles in one of our systems. i am sorry for causing much trouble to clients and relevant parties. cryptocurrencies don't have a centralised register. their strength, in theory, comes from having a connected, distributed register

called a blockchain. a transaction is ordered by putting the currency into groups, call blocks, which link to and verify the previous block. the stolen coincheck assets were said to be kept in a hot wallet, which is part of the exchange connected to the internet, as opposed to a cold wallet, where funds are stored securely offline. coincheck said it will issue full refunds to all of the 250,000 of its users who have become victims of the hack. but will that be enough? translation: my total losses are about1 million yen. i was shocked. i'm finding it difficult to trust virtual currencies anymore. 0thers probably will no longer invest in them. translation: money cannot be kept in insecure places. i won't consider investing unless there's a reliable platform providing such services. world leaders meeting in davos last week issued fresh warnings about the dangers of cryptocurrencies, suggesting they risked being used for illicit activity. will the coincheck theft now

prompt legislators to act? rhodri davies, bbc news. a french climber stranded on one of pakistan's highest peaks has been flown to hospital after a rescue operation. but the search for her polish climbing partner has been abandoned, as tim pattinson reports. a dramatic rescue operation on one of the world's highest and most deadly mountains. an elite climbing team was rushed to the rescue after two climbers became stranded. as part of this daring, high—altitude mission, the team was dropped more than 1,000 metres below the lost climbers' last—known position. they scaled the mountain overnight, eventually finding the french climber elisabeth revol alive. a friend and fellow mountaineer described the rescue attempt. they started their very heroic and extraordinarily fast seven—hour

climb towards her. she was able to start moving, and that's what, perhaps, saved her. because, had she stayed where she was, it's not certain at all whether they would have been able to reach in time. elisabeth revol has now arrived in the capital, islamabad, and is being treated for frostbite. but the whereabouts of climbing partner remain unknown. tomasz mackiewicz had become separated. he was reportedly suffering from frostbite and snow blindness. now, the search has been called off, due to bad weather and treacherous conditions. tim pattinson, bbc news. for more than five decades a group of around 4,000 members of the shona community, from zimbabwe, have been living in kenya. their forefathers arrived as evangelists, but they have never been recognised by the kenyan government. now, they are not recognised in zimbabwe either, making them stateless. the bbcs merchuma reports. 88—year—old mofat ngwabi lives in kinoo, outside nairobi.

he is one of the few shona people still alive who arrived in kenya in the 1960s. translation: jomo kenyatta told our leaders that they could go anywhere in kenya and preach, even to the maasais. we cannot do any business to feed ourselves. it's very difficult. when you construct something to sell, and the authorities find out, you get arrested. despite that meeting, and the blessing of the president to establish a charge, the shona could not be registered because, under the first post—independence constitution, there was no provision for non—kenyans to be registered as citizens. it has left them stateless today, without kenyan or zimbabwean citizenship — a huge problem for mofat‘s growing family, which now numbers seven children, nine grandchildren, and two great—grandchildren, who were all born in kenya. the kenyan government was not

available for comment. shona men specialise in carpentry and construction work and other labouring jobs that do not require identification. only those who have married a kenyan have obtained one. the women do basketry. the shona are known for religious piety. the first generation came to kenya to help spread the christian message and their faith remains central to them. the shona people have lived in kenya for the past six decades, and this church is the only property they own as a community. every day, they hold prayers here three times, hoping that their plea for an identity will be heard. the united nations refugee agency says it wants to end statelessness,

affecting an estimated 10 million people worldwide by 202a. we're trying to raise the profile vis—a—vis the kenyan authorities, write their story, explain who they are, how many they are, under which circumstances they came, and why today they're here, how they're struggling for their lives, for the lives of their children, and trying to devise with the kenyan government a way out. going back to zimbabwe is not an option for them. they say a few of them attempted the journey, but were turned back by the zimbabwean government. merchuma, bbc news, nairobi. the man who founded ikea and revolutionised the furniture industry, ingvar kamprad, has died at the age of 91, at his home in southern sweden. joe lynam reports. ingvar kamprad can safely be described as a retailing genius. born in 1926 in southern sweden, he started selling matches aged five, then seeds and then pencils. at 17, he formed ikea,

named after his own initials and the area where he was born. now, it is probably the best known furniture store in the world, with more than 400 giant shops, and annual sales of £30 billion. kamprad was inspired to create the idea of flat—packed furniture when watching someone remove the legs off a table to fit into a customer's car. he disowned his previous support forfar—right parties in sweden, during the war, and lived a modest lifestyle. his house and possessions did not reflect his wealth. translation: i don't think i'm wearing anything that i haven't bought at a flea market. that's because i want to give a good example. if we're going to be conscious about our economy, one can't just talk about it. one has to show that. the genius of ingvar kamprad was to persuade millions of people to come to his giant superstores, pick out products that they may like but not necessarily need,

and then collect it in person from the warehouse and, crucially, assemble the whole thing at home. we are used to it now, but at the time, it was laughed at. and today, one famous designer tipped his hat at what ingvar kamprad had achieved. he actually tapped into the taste that every ordinary person wanted. so they could get this new wave of modernity that was coming about in the 1950s, and he managed to trap it and make it available to everybody. ikea said ingvar kamprad, who was involved with the business right up until recently, would be much missed by his family, and warmly remembered by the company's employees worldwide. hello there, good morning.

winter is set to return this week but nothing too serious, nothing out of the ordinary. what was unusual was the temperatures we had over the weekend — 15 degrees in that mild south—westerly on sunday. there's colder air to come down from the north, and it comes in initially behind this weather front here. that is moving southwards, it's been bringing the rain that we've had across the northern half of the uk. and that rain, on monday, is moving south across england and wales. behind it, we're starting to see some colder air already, by the morning, in scotland. maybe some wintriness over the tops of the high ground, as those showers come in. one or two showers coming into the north of northern ireland, but much drier, by this stage, after some heavier rain overnight. here's the rain though, across the north—west of england and wales, where it could be heavy over the hills. south of it, still some gusty winds for a while, but very mild air — temperature 9—10 degrees early in the morning. get a bit of sunshine in the south—east, and those temperatures could rise a few

degrees higher in the morning. that's ahead of the rain. here's the rain. it's moving southwards and, as it moves southwards, so the rain becomes lighter and more patchy, but it will drop the temperatures across southern areas in the afternoon. we get some sunshine following behind that in wales and the midlands. and further north, some sunshine, a scattering of showers, and again, just cold enough to give us some wintriness over the higher ground in scotland. but it gets cold overnight where we have the clearer skies, across southern and eastern parts of england, in particular. could be a frost returning by early tuesday, but we start with some sunshine across most of england and wales. and gradually, through the day, the tendency is for things to cloud over more and more. a little bit of drizzly rain coming into the far south—west, but the wetter, windier weather is in the north—west of scotland. in between, it looks like it's going to be largely dry. but temperatures 6—9 degrees — that's nearer normal for this time of the year. now, it may start to feel colder around the middle part of the week. these weather systems do move through. this one the more significant one, coming down from the north—west, sweeping down across the uk, and then it introduces another bout

of colder air that will sweep across all areas, and the wind direction changes once again. so we're going to find more in the way of showers on wednesday. we've still got this band of rain on the weatherfront, to clear away from southern areas, and then it's sunshine and showers. but those showers will be more wintry, notjust in scotland but as far south as wales, perhaps into the peak district as well. nothing serious, but a change from what we've been seeing. and it will feel colder, as well, given some strong to gale—force winds — 11—5 degrees typically across the north. wind direction changes to a bit more of a northerly, so more inland areas will be more sheltered, so inland parts probably dry on thursday. the showers more likely around exposed coasts. but again, it will feel colder in the wind. this is bbc news, the headlines: there is an ongoing attack in kabul

at the marshal fahim university. five attackers have been involved, three have been killed. two national army soldiers have been killed. aid groups in yemen say new fighting in the port city of aden has made an already bad humanitarian situation worse. at least ten people were killed on sunday during fighting between former allies — separatists who want independence for south yemen, and forces loyal to the saudi—backed government. police in moscow have released the russian opposition leader, alexei navalny, after detaining him at a rally. his lawyer says he will have to appear in court, where he may face charges. now on bbc news it's time for hardtalk.
