this is bbc news, i'm lewis vaughan jones. our top stories: early results are showing strong support for senator bernie sanders as the race to ta ke bernie sanders as the race to take on president donald trump moves to nevada. as the number of new cases of coronavirus in south korea more than doubles in one day, the prime minister says the the situation is grave. hello and welcome to bbc news. supporters of the democratic party in the us state of nevada have been taking part in caucuses to select their preferred candidate to run for president.

the left—wing senator bernie sanders is the frontrunner in the state while a few other candidates need a good result just to keep their campaigns alive. joe biden has already declared some success with a rejuvenated campaign. are you know, i know we don't know the final result yet but i feel really good. you've put me in position. the press is ready to declare people dad quickly, but we are alive and we're coming back and we we're going to win! cheering sophie long is in nevada's largest city, las vegas. hi, sophie. ican hi, sophie. i can see you're at the biden campaign. is his campaign off life support? no, ithink campaign off life support? no, i think it's come off life support now. joe biden is in the crowd behind me, having selfies taken with his wife, jill. internally they're saying they've come second stoppage we only have a small amount of the

results officially according to the nevada democratic party but us media outlets are already calling this a resounding victory for bernie sanders. he was always expected to do very well here, he was leading in the polls both nationally and in nevada, strong support base with the latino community, which make up a third of the population in nevada, so us media outlets already calling this a success for bernie sanders and we're hearing joe biden‘s team, to internal data, are saying he's come a very strong second. he needed to do that, he had a very lacklustre performance in new hampshire and iowa and he needed to regain the momentum here to ta ke regain the momentum here to take him onto south carolina and then super tuesday in just over a week, which is really important, a massive delegate haul on offer there. it's fair to sayjoe biden‘s campaign is off life support. he's still on the stage behind me and moments ago he said this is the moment, we're going to move from here and win. a good night forjoe

biden but one, as you rightly point out, he very badly needed. talking about moving on, we understand bernie sanders has already started campaigning in texas, one of the super tuesday states. is he unstoppable? yeah, bernie sanders already moved on some of the other candidates as well. onlyjoe biden, pete buttigieg and tom ‘s tyre remain in nevada, a sign how important super tuesday states are. they go to the polls on march the third. bernie sanders isn't yet unstoppable but there is concern in the democratic party that with this boost tonight, he will go to super tuesday in a strong position and if he does well with super tuesday, it is possible when the polls close in states like california and texas, he will have accrued and texas, he will have accrued an insurmountable lead. that will be a good thing for bernie sanders and his campaign, of

course, but a problem for some people in the party who think he is too progressive. a long way for the democratic party to go yet. a long way indeed. sophie long in nevada, thank you very much ford joining us. —— forjoining us. in south korea, officals say the number of new coronavirus cases has more than doubled in one day to 433. the prime minister described the situation as grave. many of the new cases are linked to a hospital and to a religious group near the south—eastern city of daegu. laura bicker is in seoul. health authorities say they're using every tool at their disposal to try to get the outbreak under control but the case numbers continue to rise. the real area of concern is a hospital, a psychiatric hospital, a psychiatric hospital where over 100 patients have caught coronavirus while in their hospital bed. to patients from there have already died. these are long—term patients with underlying health conditions. now, the investigation into how

this outbreak started centres around the church ofjesus, a religious sect with over half a million members across south korea. around 9000 of whom are said to be at risk. they've been told to put themselves into quarantine and in interviews, over 1000 said they have symptoms of coronavirus. that doesn't necessarily mean they have the virus, they have to yet test positive. when it comes to the rest of the country, the highly affected area of daegu stadium, where they have the most number of cases, the mayor there has asked of the 2.5 million residents to stay—at—home if at all possible. the defence ministry has put all south korean bases on lockdown after three different soldiers from three different soldiers from three different soldiers from three different provinces came down with coronavirus, and although it is centred around one region, a number of outbreaks keep cropping up all

over the country, concerning health authorities here. the good news is south korea was very well prepared for this. it had hospitals and medics on standby but even they seem surprised by how quickly and rapidly this virus is spreading. have a look and our website for more, or download the bbc news app for more information on the coronavirus. turning back to asia, and the largest cluster of coronavirus cases outside china has been on board the diamond princess cruise ship, docked in yokohama in japan. more than 620 people on board tested positive for the virus, but passengers from around the world have gradually been leaving after a two—week quarantine. among them were 30 british and two irish holidaymakers who arrived in the uk on saturday morning, and have now been taken to hospital near liverpool where they will spend the next fourteen days in quarantine. fiona trott has the story

of their journey from japan. arriving under police escort, and at a hospital in the north—west of england. this wasn't the return they once imagined. no relatives to greet them here. instead, a team of nhs staff, who took them to their room. this is where they'll spend the next two weeks, a nursing accommodation block at arrowe park hospital. staff here have already looked after travellers from china, and know what to expect. the group of people is slightly different. 0bviously they've come from a cruise ship, rather than from their own homes over in china. but we're working exactly the same as we did before with the healthcare professionals, public health england, to make sure that they are safe and well managed and comfortable whilst they're with us. after a delayed 12—hour repatriation flight, they arrived back in the uk this morning.

but not all the british tourists who were on the cruise made this flight. in the end, 30 britons and two irish citizens landed in wiltshire and got on these coaches, leaving behind some of the ship's crew, many of whom are still on board, and at least four holidaymakers who contracted the virus on the cruise. two of them are david and sally abel, who also have pneumonia. at first, they were relieved at the hospital care they received. today, theirfamily are anxious and angry. my dad is, like, saying, "this — i can't do any more of this, son. you need to get me out of here. it's like prison in here. we've got no washing facilities. we've got one toilet to share. we have a small window in our hotel room, which overlooks a brick wall, which is six inches away. we've got no natural daylight coming into the room. it's awful. no treatment." some passengers say their patience has also been tested. they've already been

in quarantine for two weeks, and say other foreign nationals were evacuated from the diamond princess before them. tonight, another two weeks of quarantine begins. they may be back in the uk, but they're not home yet. fiona trott, bbc news, the wirral. flooding misery continued in many areas around britain with south wales and worcestershire badly affected and firefighters rescuing people from their homes in the yorkshire dales. water levels have fallen back in most areas today, allowing the cleanup to start on affected homes and businesses. robert hall has more. below the battlements of knaresborough castle, the normally lazy river nidd had become a muddy torrent, fed by hours of rainfall over the yorkshire dales, creeping once more towards riverside homes and businesses. villages around the market town of settle had borne the brunt of the new weather front. locals filmed these images of flash—flooding, which cut roads in and out of

horton in ribblesdale. back in knaresborough, the owner of mother shipton‘s cave, a popular tourist attraction, was waiting to begin yet another clear—up, as the visitor season loomed. i mean, i've had the park eight years now, and it's getting worse, i have to say. i thought two years ago was bad, but obviously it's come back to haunt us now. they were clearing up in cardiff, too, 100 volunteers helping to remove six tons of debris left by the river taff at bute park. in worcestershire, chris walter stood in the ruins of his business and said he was giving up the fight to survive. i just can't cope with it anymore. i was flooded in 2007, and that was pretty traumatic. but this time, you know... during the day, river levels have fallen back, the highest flood alerts have been downgraded, and many roads reopened. tonight, the environment agency said there was a slow improvement along those rivers most affected

by the recent bad weather. and that respite should continue tomorrow, but further heavy rain forecast for this region on monday means there is a risk of further disruption. robert hall, bbc news, on the river wharfe in west yorkshire. boxing, and tyson fury and deontay wilder are preparing to face each other again in in las vegas for the wbc world title. it's almost 15 months since the pair fought out a controversial draw and tickes have been exchanging hands for thousands of dollars. sport editor dan roan is at the mgm grand hotel in las vegas. the wbc title, the most prestigious of the four belts, is on the line. it is such a big fight because these are undefeated fighters. remember, they're widely considered to be the two best heavyweights in the world right now. and if it is anything like as good a bout as you mention just then, some 15 months ago, in los angeles, when it was a draw, and remember, fury outfoxed his american opponent for a large part of that fight, and miraculously, memorably,

climbing off the canvass in the final round, and was unlucky not to get the win, we're in for another epic classic. but of course, if wilder can win, he is one of the most feared punchers in the history of this sport, then that will reinforce his status as a dominant force in boxing. one thing is for sure, this feels like something of a throwback to the glory days of this sport. it is a boxing occasion to savour. dan roan. there are new hopes of a peace deal in afghanistan, with the start of seven days of what's being called a period of reduced violence between us—led forces and taliban fighters. it could lead to the withdrawal of foreign troops after nearly two decades of war. from kabul, secunder kermani reports. celebrations late last night, as the reduction in violence came into effect. for the next week, the taliban, afghan government and us forces have promised not to carry out major attacks, helping pave the way, it is hoped,

for an eventual peace deal. war has torn this country apart. this was a taliban suicide bombing last september, which killed 12 people, including an american soldier. it led the us to suspend talks with the taliban, just as a deal was about to be signed. but president trump wants an exit from the united states‘ longest ever war. taliban wants to make a deal. we'll see if they want to make a deal. it's got to be a real deal, but we'll see. talks with the taliban resumed earlier this year. the two sides have drawn up an agreement that would see a timetable established for the withdrawal of american troops in exchange for the taliban breaking links with groups like al-qaeda. if the next seven days pass off peacefully, it will be signed next weekend. translation: it depends how honest the taliban are. if they do what they say, we will have peace.

if they don't, they are just playing with us. but, even if the us—taliban agreement is signed, that won't be the end of this conflict. instead, it will signal the start of a new set of discussions, this time between the taliban and other, at times feuding, afghan political leaders. together, they will need to establish a longer—lasting ceasefire, and decide how the country should be governed in the future. for many afghans, the immediate priority is peace. more than 3,000 civilians lost their lives here last year. now there is a chance, at least, of an end to the violence. secunder kermani, bbc news, kabul. a man has appeared in court charged with carrying out a knife attack at a mosque in central london on thursday. daniel horton is accused of stabbing raafat maglad, who's in his 70s. jenny kumah gave us this update from westminster magistrates court. daniel horton appeared in court this afternoon. he sat for most of the hearing with his head down.

he spoke to confirm his name, age, and described his nationality as british. he is charged with grievous bodily harm and possession of a bladed article. he is accused of attacking a 70—year—old mosque official on thursday afternoon. raafat maglad was taken to hospital and treated for a wound to his neck. he was back at prayers the following day. now, the prosecutor says that mr maglad and the defendant would have known of each other. the defendant had attended the mosque for a number of years. now, the court heard that daniel horton has no fixed address. he has been remanded in custody and he will appear at southwark crown court on 20 march. now, i should say that the police say they do not believe that this incident is terror—related. this is bbc news, the headlines: the next phase of the contest to choose a democratic challenger to president trump is underway in nevada. early results are giving

bernie sanders the lead. let's stay with this story. in his post— caucus speech, one of the contenders, now pete buttigieg, spoke about avoiding extremism and made clear that his main aim is to beat senator sanders. and i congratulate senator sanders on a strong showing today, knowing that we celebrate many of these same ideals. but before we rush to nominate senator sanders in our one shot to take on this president, but us take a sober look at what is at stake for oui’ look at what is at stake for our party, for our values, and for those with the most to lose. there is so much on the line. and one thing we know for sure is that we absolutely must defeat donald trump and everything that he represents in november. let's bring you in some pictures from the bernie sanders campaign, because he is no longer in nevada. as you might guess from that flag, he is in texas, in san antonio.

there is a reason for that. texasis there is a reason for that. texas is one of the 1a states which will vote on super tuesday, much of the third. senator sanders clearly wants to steal a march on the others. —— march three. he is really the frontrunner now, coming equal first the frontrunner now, coming equalfirst in iowa, first in new hampshire, and now first in the as well. we will keep an eye on the podium and we will see when he comes to the stage. police in kazakhstan have detained about 200 people during demonstrations in the country's largest city, almaty. the arrests came after two banned opposition groups tried to hold illegal anti—government protests. this report from the bbc‘s rich preston. shouting. these demonstrations were not supposed to turn violent. in fa ct, supposed to turn violent. in fact, they were supposed to happen at all. the two groups protesting our banned. there is no official political opposition in this oil—rich central asian country. the democratic party was created last year but is not formally

recognised. the other party, the democratic choice of because it's done, was labelled an extremist group by the government in 2018. demonstrators were met by huge numbers of police. this man, eric, is sharing his views of the government. before plainclothes police officers taken away. down with a dictatorship, showers shouting. the science as "political repression is a disgrace, detentions for peaceful rallies". security forces were unrelenting and who was arrested. translation: this lawlessness must not be left without responsibility. those in power must take responsibility. they didn't ask for people's opinions. they got used to trampling people's opinions and their lives. the democratic party of because it's done will rise. —— of kazakhstan. kazakhstan is often criticised for its

authoritarian regime and the limiting freedom of speech. when president tokayev took office last year, he promised to change that, and to ease restrictions on public protest. but there is little sign of change. civil society groups say they are not happy with the proposed reforms and dissent on the streets is short lived and met with a swift, heavy—handed response. south sudan's president salva kiir has called for reconciliation following a bitter civil war and "forgiven" his rival riek machar, who has been reappointed as first vice—president. the former rebel leader was sworn in to be the country's deputy leader with a new peace deal set to end six years of conflict. the bbc‘s catherine byaruhanga reports from the south sudan capitaljuba. the man of the moment, riek machar, arrived — shaking hands, hugging, and smiling. so help me god... the former rebel leader was sworn into office before his arch rival, president salva kiir, and promised they would now

serve their people. i want to assure you we will work collectively to end your long—suffering. millions of south sudanese are living in camps like this one, both here and in neighbouring countries. many are too scared to go back home after experiencing brutal violence. hundreds of thousands of people are estimated to have been killed in the past six years. their president says change has come and they should prepare to return. he says it's time to heal old wounds. i have forgiven my brother, riek machar, and first vice president of the republic of south sudan. applause. and i also ask for his forgiveness.

applause. live now to bernie sanders, the presumed winner of the nevada caucus. he is now in san antonio, texas. of course, all the votes are still being counted, but he has clearly decided to move onto the next eight and he is about to address his supporters there stop chanting: bernie, bernie, bernie! thank you! thank you, san antonio! let me introduce to you the next first lady of the united states! cheering. you will be very proud of her as
