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. bill hayton reports. this is a war within a war. the southern city of aden 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 warmer 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 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 oui’ 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. this 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. more than 100 people are now confirmed to have been killed, and 230 injured, in saturday's suicide bombing in the afghan

capital, 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. some breaking news to bring you: we are getting reports of a new attack in kabul, this time on the marshal fahim national defence university, which is the country's highest military academy. there are reports that sound of explosions and small arms fire can be heard in the area. we will bring you more on that as we get it from our team in kabul. 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. there has 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. prayers were also said for him in the city's cathedral. marco antonio had been out taking photographs, but was arrested and accused of stealing the camera. two of the policemen involved in the arrest have been detained. 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.

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 has 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. 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 relative 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 abouti 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. the world of popular music is taking a moment to pat itself on the back with the 60th grammy awards. many of the stars in attendance at new york's madison square garden are wearing white roses in a display of solidarity with the anti—sexual harassment me too movement. let's cross live to new york, where we can speak to the bbc‘s nada tawfik.

so far kendrick lamar has been the big winner on the night, picking up four grammys including best rap album. bruno mars has three awards, including best r&b album, and ed sheeran has two awards including best pop album. first of all, is the music industry catching up with hollywood and tv in terms of time's up hollywood and tv in terms of time's up and me too? yes, it is certainly trying to. the group reallyjust a few days before the grammys called voices in entertainment formed and came up with the idea of white roses to show solidarity with the victims of sexual abuse. and i was on the red carpet earlier and you really did see the majority of men and women wearing those, the really send a powerful statement, a lot of them

saying the music industry has a voice, that people listened to it, and it is necessary to get on this conversation. i spoke to cyndi lauper, for example, who said she wa nts to lauper, for example, who said she wants to seat safe work spaces for women, she wants to see equal pay, she wants to see women supported, and she will later be performing this evening with kesha when she performs her very powerful song called praying, that is actually directed at herformer called praying, that is actually directed at her former producer who she has accused of sexual assault. he has denied that but they have beenin he has denied that but they have been ina he has denied that but they have been in a legal battle for years, and so that is gearing up to be one of the most powerful performances of the night. and activism aside, what about the winners? who is having a good night there? well, kendrick lamar is having a fantastic night. he basically keep off the grammys with a performance with cameos by u2

and dave chappelle, and then he picked up awards for best rap performance and best rap album, and in the preshow awards he got three grammys, so he is doing quite well tonight. alessia cara got this new artist, and for the first time ever the grammys has televised the best comedy album, that went two dave chappelle. now, ed sheeran, who was blocked out of the major categories got the win with best solo pop performers, and the night has had a star—studded series of performances from the likes of lady gaga, bruno mars, and more to come. stay with us on bbc news. still to come: tributes to the father of flat—pack furniture, and founder of ikea, who has 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. more than 100 people are now known to have been killed in saturday's suicide bombing in the afghan capital, kabul. the country has been observing a day of national mourning. the river seine in paris has risen still higher on sunday, though the authorities believe the city will now be spared really major flooding. still, the waters are six metres higher than usual and the clean—up job will take weeks. kevin connolly is in paris. predicting extreme weather is always problematic. the river is continuing to rise here, but the maximum point it's now expected to reach is not as high

as it was a couple of days ago, and it's not thought likely to reach the levels we saw during the floods of 2016, for example, when paris was flooded. you can see there the boats tied up because with the level at these levels, —— river at these levels, the boats do not fit under the bridges. the people of paris are adjusting to the landscape. the police here have issued a warning that you should not swim or go canoeing in the river — not a warning that most of us, of course, have needed. this has been a winter of exceptional rain in france — some regions have seen levels that they've not seen since the 1950s. the peak of river seine flooding is likely to be reached some point between sunset on sunday night and dawn on monday morning. but the consequences of this kind of flooding, especially in communities further out in the seine valley, will take a very long time to

resolve. people will be living with the consequences of this swollen, searching river for weeks the consequences of this swollen, searching riverfor weeks if not months. here in the uk, the prime minister theresa may is coming under new pressure about her leadership and her policy on brexit. 0ur political correspondent chris mason reports. if it felt a little bit chilly for the prime minister at the world economic forum in switzerland last week, well, the politicalforecast is not looking much sunnier for her now she's back home. some of her mps are fed up with what they see as her merely muddling along in office. and on top of that, some of those who campaigned for brexit fear it being diluted to such an extent it never really properly happens. it is very complicated and that is one of the reasons why i have advocated and supported compromise, but there is only so far you can go with compromise without ultimately finding yourself in a position where you are selling out all the people who voted to leave. the government says it is committed to delivering brexit,

but you know when a party is falling out with itself when senior figures, like this man, who is effectively the prime minister's deputy, have to say this. the conservative family, left, right and centre, because we're a broad church, needs to come together in a spirit of mutual respect. you know, there are differences in any broad church and look at what the bigger picture is showing. the next stage of brexit negotiations is about what happens immediately after we leave the european union at the end of march next year. for around two years freedom of movement will continue. the government will introduce a registration scheme to new arrivals. the rights of eu citizens here and uk citizens in the eu look set to remain the same, and eu laws will continue to apply. the labour leader is facing his own divisions in a party that predominantly voted to remain in the eu, and many whose supporters, polls suggest, would like a second referendum, butjeremy corbyn says no to that.

what we asked for and demanded in parliament has been a meaningful vote in parliament at the end of it. so mps could... i thought the people decided, not parliament. what happened with this bill was it was an undemocratic power grab by the government. we are not asking for a second referendum. and you're not going to. tomorrow, the rest of the eu will get together in brussels to sign off its approach to the transition or implementation period. brexit negotiations are about to crank up again. for more than five decades, a group of around 4,000 members of the shona community from zimbabwe have been living invisibly among kenyans. theirforefathers arrived in kenya as evangelists but they have never been recognised by the kenyan government. now, they are not recognised in zimbabwe either, making them stateless. the bbc‘s merchuma reports. 88—year—old lives in nairobi, he is

one of the few shona people still alive to arrived in kenya in the 19605. alive to arrived in kenya in the 1960s. inflation macro he told our leaders they could go anywhere in kenya and preach, even to size. we cannot do any business to feed ourselves. it is very difficult when you construct something to sell the authorities find out you get arrested. —— masais. authorities find out you get arrested. -- masais. despite the meeting and the blessing of the president to establish a charge, the shona could not be registered because under the first postindependence 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 to his growing family which now numbers seven children, nine grandchildren, and two

great—grandchildren who were all born in kenya. kenyan government was not available for comment. shona men specialise in carpentry and construction work and other labouring jobs that do not require identification. 0nly labouring jobs that do not require identification. only those who have married a kenyan have obtained one. the women do basketry. the shona unknown for religious piety, the first generation came to kenya to help spread the christian message and theirfaith help spread the christian message and their faith remains central to them. the shona people have lived in kenya for the past six decades in this church is the only property of the 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 try to raise the profile with a kenyan authorities, write their story, explain who they are, how many they are, under which circumstances they came, and why today they are here. how they are struggling for their lives, the lives of their children, and trying to devise the kenyan government a way out. going back to zimbabwe is not an option for them. they say a few of them attempted to journey but returned back either zimbabwean government. the man who founded by ca re government. the man who founded by care and revolutionised furniture furniture has died at the age of 91 at his home in southern sweden. 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's 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 of a table to fit into a customer's car. he disowned his previous support for far—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 are 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. you are watching bbc news. i'm duncan golestani. stay with us. 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 in to the north of northern ireland. 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, 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 showers, and again, just cold enough to give us some wintriness over the higher ground in scotland. it gets cold overnight where we have the clearer skies across southern and eastern parts of england, in particular. there could be a frost returning by early tuesday, but we start with some sunshine across most of england and wales. gradually through the day, the tendency is for things to cloud over more and more. a 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 near normal for this time of the year. 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. 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 weather front, 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: 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. more than 100 people are now known to have been killed in a suicide

bombing in kabul on saturday. attackers drove an ambulance past a police checkpoint to get to a crowded street in a district full of government buildings and embassies. we're getting reports of a new in kaboul. 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. thousands protested in cities across russia in support of his call for boycotting the upcoming presidential elections. now on bbc news: the week in parliament.
