this is bbc news. the headlines: the death toll from the coronavirus rises to 41 — with authorities in china struggling to contain the outbreak, as millions travel for the lunar new year. benita mehra, a newly—appointed member of the grenfell tower inquiry panel, resigns after being linked to the charitable arm of the firm which supplied the tower block's cladding. donald trump's lawyers have begun their defence of the president in his impeachment trial in the senate — they say he's done nothing wrong. the search for survivors continues after a powerful earthquake hit turkey — at least 22 people have been killed and more than 1,200 injured. and we'll be taking an in—depth look at the papers with our reviewers martin lipton and lucy beresford at 10:30.

china's president has warned that the spread of a potentially deadly new virus is accelerating, with his country facing a "grave situation". coronavirus has killed at least 41 people and infected more than 1,300 since the outbreak began in the city of wuhan. severe travel restrictions have been imposed in many areas. here, the department of health says 31 people tested for the virus have been given the all clear. tonight, the foreign office has advised against all travel to wuhan city and said that anyone still in the area who was "able to leave should do so".

and we will find out how the corona virus spread and other stories covered in tomorrow's front pages at 1030 and 1130 this evening in the papers. 0ur 1030 and 1130 this evening in the papers. our guests are martin lipton chief sports reporter for the sun and the broadcaster lucy beresford. while authorities were doing everything they could, the screening measures would have a limited impact if those infected were not showing any symptoms. you can detect for the presence of the virus but the virus has to get levels which are high enough for the assays to detect them. the other key issue here is people only start developing symptoms if they are going to develop symptoms after a few days of

incubation. we don't know what the period of incubation is for this novel coronavirus. it could be two days, ten days or more and whilst being incubated, the person won't show any outward signs and if they are travelling around china or other parts of the world, they can be carrying that infection with them. we talk about similarities with sars and so on, what can scientists predict about how the presence of this virus may change and develop and the kind of challenges. in 2002 we saw the emergence of sars and in 2012 we saw the emergence of mers coronavirus but the trouble is at the moment this virus does not fit the moment this virus does not fit the pattern they have shown and importantly the pattern were most transmission is associated with severe disease. the real concern as well is that this virus seems to be showing quite a reasonable amount of

human to human transmission, so one person gets infected passes it to pay b passes it to patient c and u nfortu nately pay b passes it to patient c and unfortunately that is quite challenging. it allows the virus to spread from human to human but gives it the opportunity to mutate, potentially to evolve and further adapted for transmission in humans. i don't want to frighten people but these are realities. just a final thought, we are looking at a country like china which seems to have mobilised quickly, they are busy building hospitals in ten days, they have resources and the ability to move reasonably fast. what is the potential for problems with viruses of this kind if they were in other parts of the world? you have hit the nail on the head in terms of some of the major concerns about other parts of the world. for example, at the moment we have seen of the world. for example, at the moment we have seen the virus turn up moment we have seen the virus turn up in very develop countries where they have fantastic health

infrastructure, good surveillance, so we can infrastructure, good surveillance, so we can identify infections and deal with them. if you imagine an infection like this going to a part of the world where the infrastructure is not so good, then it becomes a whole lot more difficult to identify and control. president trump's lawers have been setting out his defence, at his impeachment trial in the us senate. mr trump is accused of abusing his power and obstructing congress. the president's attorney said his accusers had no evidence — and their real motive was to undermine mr trump's re—election campaign. we'll have a full report on this story in a few minutes' time when viewers on bbc one join us for a round up of the day's news. first though i've been speaking to laurie laird — an american politics commentator and to the politico reporter daniel lippman — who explained what the trump defence was trying to achieve in their opening arguments. if you watch the couple of hours of the defence, this was heavily focused on poking holes in the democratic arguments and also previewing

what we will hear on monday where we are expected to hear lots of attacks on joe and hunter biden's work in the ukraine and making the point that trump has done nothing wrong and that this would overturn an election. interesting as well is that attempt to unpick the prosecution's case. there was a wider message about the motivation of the democratic movement. the defence is not engaging with the facts here. the arguments that we have heard today we have heard over and over and over. look, donald trump did release that aid for ukraine, so how could there have been a quid pro quo? there were questions about the whistle—blower who brought that phone call on july 25 to light. was the whistle—blower biased? the inspector general of the cia found there may be some biase, but the concerns were legitimate. but we have heard these arguments before. what we haven't heard yet

is donald trump did not do this. what we have heard is what donald trump did was perfectly fine. daniel, the message as well seems to be this isn't about the details as much as the fact that we are denying the american public their right to have a say in all of this come november. yes, and that also we would be reversing the november 2016 election, but if you were watching those two hours this morning, you can't help yourself but think that they were ignoring the facts of their own. one thing that the trump lawyer said is that the ukraine leader did not say or did not know there was any hold on his aid, when in fact we have evidence that a number of ukrainian officials knew that day that there were problems with the aid. he also said that trump did not make this an explicit quid pro quo,

he didn't say those words, i will only give you the aid if you give me those investigations. but i think that would not be in trump's m—0. he is not, he knows people are going to be listening on the call, he is not going to explicitly make a mobster—like statement like that because he knows that would leak and if he said it in a more nuanced fashion, that would be less likely to get out there. daniel, let me just stay with you for a moment because you are there in washington. donald trump making the point that he was cheesed off this happened on a saturday because he wouldn't get the ratings that he wanted. how much interest has there been today? a fair amount but not... it was mostly the professionals who were paid to watch it. most americans have regular lives, taking care of their kids, doing errands on saturday, they are not going to be watching this whole proceeding. they will see some of the coverage

but there is plenty of time for the defence to make their case on monday with more eyes on this. but i think what trump is saying makes the point that for him, optics are everything and so he is very carefully attuned to how this is playing on television, if there is a number of eyeballs that he wants and i think he wants to make this a show for the defence.

china's president warns that his country is facing a grave situation — as the coronavirus outbreak spreads. more than 50 million people in china now face strict controls on their movement. we report from inside the isolation zone — where the outbreak began. the police have told us that we can drive in but we can't drive out. so it seems that this whole province where the coronavirus first broke out is now going to be locked down. here in the uk — 31 people tested so far have been given the all—clear. also tonight — a member of the grenfell inquiry panel resigns — over her links to a company that supplied the tower block's cladding. rescuers search for survivors after a powerful

earthquake strikes eastern turkey — many people are missing. commentator: many people are missing. he's got him! and in cricket — an impressive england take control — in the final test against south africa. good evening. china's president has warned that his country faces a "grave situation", as the deadly coronavirus spreads with increasing speed. tens of millions of people in china are now facing strict controls on their movement. the virus is known to have killed more than a0 people — with more than 1,300 people infected since the outbreak began in the city of wuhan. here, the department of health says

31 people tested for the virus have all been given the all clear. 0ur china correspondent stephen mcdonnell has been to the province of hubei — much of which is under strict quarantine — and has sent this report. the approaches to hubei province are like scenes from an apocalyptic movie. only after a temperature scan can you pass these checkpoints. the unwell are not allowed to travel. what's more, the lockdown is spreading. roads out of the infection zone are being closed. so, basically that's the border that way. the police have told us that we can drive in but we can't drive out. so it seems that this whole province where the coronavirus first broke out is now going to be locked down.

we cross the border and drive through ghost towns. instead of lunar new year celebrations, people are in survival mode. 0n the first day of the year of the rat all these shops are closed, there is pretty much nobody on the street here. i mean, this isjust one of the towns you come across when you first enter the province and people just don't know for how long it's going to be like this, for how long they have to stay indoors or risk being infected with this potentially deadly coronavirus, which causes pneumonia. hospitals here have been flooded with patients. there are thousands who are unwell but are not sure if their symptoms mean it's the coronavirus. one man inside this hospital speaks to us from his hospital bed. he said he hasn't been told if he's contracted the potentially deadly virus. but he's worried he could catch it

anyway from others in his ward. i wish him a speedy recovery and the police arrive as if on cue. they won't confirm if a province—wide lockdown of 60 million people is about to start. but local officials want us to leave. so, as night falls, they escort us back across the border. stephen joins us now crossing into the neighbouring province of henan. the president now speaking of a grave situation for the country as a whole? here in henan the authorities have their own headaches to deal with in this city, the city is on the border, transport restrictions are in place. think of how much worse the situation can become. in wuhan thousands of people left their seeking help in other cities before it was shut down. they were taking the virus with them and so for this

reason the chinese government is considering in the megacities of beijing, shanghai implementing more restrictions on people's movements. stephen, thank you. a newly appointed member of the grenfell tower inquiry panel has resigned this evening — after she was linked to a charitable arm of the firm which supplied the tower block's cladding. benita mehra tendered her resignation to the prime minister borisjohnson, saying she recognised and respected the "depth of feeling" among some about her appointment. grenfell survivors and bereaved family members had threatened to boycott the inquiry if she remained on the panel. 0ur political correspondent iain watson, is with me. what's happened here then, iain? it is worth reminding ourselves this inquiry is into how 72 people lost their lives when highly combustible cladding caught fire in 2017 engulfing their tower block. since that happened, of course, there is going to be a new phase of the

inquiry that get under way next week and there was a threat of a boycott by the families unless the need to bonito mera resigned. it was revealed that when she was the president of the society that society received £70,000 from the charitable arm of the american company that made the cladding. she has written to the prime minister to date and said she would be impartial if she contributed to the inquiry but doesn't want to cause further distress to people who suffered unimaginable losses and that leaves borisjohnson in the position of trying to find another expert to a point very quickly before the second phase gets under way. —— benita mehra. this isn'tjust a technical matter, it is highly political, because it has to be seen as delivering on his pledge to the families and wider communities to get to the truth. a major rescue operation is continuing for a second night in eastern turkey, where an earthquake has killed dozens of people —

with many more missing. more than 1,000 people are known to have been injured in elazig province. teams are working in freezing temperatures, to reach survivors trapped under collapsed buildings. 0ur correspondent richard galpin report contains some distressing images. she isjust she is just five years old and covered in blood. but this girl is now safe. the rescue team pulling her out from under the smashed blocks of concrete and other debris brought down by the earthquake. and she isjust one brought down by the earthquake. and she is just one of more than a0 people to have been rescued here so far. for the rescue teams, speed is now essential to save lives in freezing temperatures. this emergency worker using a mobile phone to speak to a family trapped underneath the debris telling them they must keep awake. the powerful

earthquake struck this eastern region of the country last night, causing hundreds of casualties as buildings collapsed. in the light of morning the extent of damage was revealed. this just one of 30 buildings to have been brought down. and hundreds of after—shocks over the past 2a hours have added to the fear in this earthquake prone region. some of the homeless have now found shelter as the temperature at night drops to —10 degrees. 0thers, though, are out on the streets. richard galpin, bbc news. a royal marine who got into difficulty during a training exercise on the cornish coast earlier this week, has died. the recruit — who hasn't been named — had been critically ill in hospital since being found unconscious in the water at tregantle beach near plymouth on tuesday night. an investigation into his

death is continuing. president trump's lawyers have begun setting out his defence, at his impeachment trial in the us senate. mr trump is accused of abusing his power and obstructing congress. the president's attorney said his accusers had no evidence — and their real motive was to undermine mr trump's re—election campaign. chris buckler is in washington for us. chris? donald trump's lawyers tried to counter some of the arguments made by the democrats' impeachment team but mainly they tried to set out a bigger picture argument, that the democrats were not really concerned with abuse of power or that mr trump had not behaved properly in office. instead, they claimed, that actually they were more concerned with overturning the vote that put him in that office in the first place. they are asking you to tear up all of the ballots across this country on your

own initiative, take that decision away from the american people. what i have learned through all my years in politics and all my years in life, if you are right and you keep fighting for the truth will prevail. we would be derelict in our responsibility if we didn't fight for the truth. you might get a sense from that that the democrats know they have no chance of removing president trump from office. they simply don't have the numbers in the senate. but a couple of miles away in the white house a very confident mrtrump was in the white house a very confident mr trump was encouraging people to tune into the televised proceedings and he was tweeting in not very flattering terms that his lawyers would not have got away with in congress about his political opponents. his team will continue to make their arguments on monday and you'd expect those arguments to become a little more pointed, a little more political and perhaps a little more political and perhaps a little nastier. chris, thank you. a year ago today, a dam above a mining village

collapsed in brazil, engulfing the community and killing 270 people. it was one of the country's worst—ever industrial disasters. 16 people from the mining company — vale — along with the mine's owner and its auditor, have been charged with murder. but few people there believe justice will be done. 0ur correspondent katy watson has returned to the town of brumadinho, to see how the community is coming to terms with the tragedy, a year on. the name of every one of the 270 victims was read out like a register. their families answering for them. a town that once thrived on mining now devastated by it. when the dam broke last year, the toxic sludge that came crashing down the valley destroyed everything in its wake. houses, hotels, farmland and forests. and this is what's left behind. 10 million cubic metres of mud that needs to be cleaned up. firefighters are still looking

for 11 people who are missing. today's commemorations brought together communities from all over the region. nobody here is untouched by this tragedy. this is as much a remembrance for those who died as it is a protest for those who are living. brumadinho was broken by what happened last year and people want justice. "my nephew wants to kill himself every day," says claudia, who lost her brother—in—law. "the mud that hit this city also hit our hearts." i ask her what she thinks about the mining company. "all vale is is destruction and death. theyjust cared about profit. nothing has changed this year apart from our pain. it's only got worse." murder charges brought against the companies involved go right to the very top. vale's former boss is among the accused. translation: vale and its workers knew the risky situation of the dam and they had demanded action but nothing was done.

today was a day for remembrance. tomorrow, they continue theirfight forjustice. katy watson, bbc news in brumadinho. with all the sport now, here's jane dougall at the bbc sport centre. hi,jane. good evening, kate. england are in control after an impressive day two of the fourth test against south africa. they got a00 in their first innings and restricted the home side tojust 88—6 in their reply so far. patrick gearey reports. test cricket's a delicate balancing act. important to remember where you are in the wider picture, while keeping your mind clear. 0llie pope has that rare clarity. this is only his sixth test. but already he seems to be on top of things. 50. he and joe root mopped up the bowling. this was getting away from south africa fast. then a fight back. first pope went, then root. commentator: this time he's got him! sam curran lasted one ball. three wickets for 11 runs with things starting to swing.

stuart broad certainly was. he battered the attack all around johannesburg. by the order, he's england's worst batsman. partner mark wood, second worst. and yet watch them go, enjoy the show. england ended up on a00. surely the series now beyond south africa. after all, the local batting's not inspired too much confidence of late and england often bowl quicker than that. around 90mph in mark wood's case. pieter malan was the first domino down. the others toppled behind him. these the shots of beaten men and tired minds. six south africans came and went. three of them to wood. on a ground 6,000 feet above sea level, england's tour must surely finish on a high. patrick gearey, bbc news. a few surprise results in the fourth round of the fa cup, but if you want to wait for match of the day, then it's time to leave the room. a poor performance from west ham saw them put out by championship side

west bromwich albion. the single goal coming from the baggies' conor townsend. and no fairy tale for championship side brentford who lost 1—0 to leicester city — kelechi iheanacho scoring in the first four minutes. it was the last fa cup match at griffin park, because brentford move to a new ground in the summer. the rest of the fa cup results are on the bbc sport website. celtic are five points clear at the top of the scottish premiership after beating ross county 3—0. elsewhere, there were wins for livingston and stjohnstone. it was a goalless draw between motherwell and hibs. second—placed rangers play hearts tomorrow. manchester city are into the women's fa cup fifth round after beating local rivals manchester united 3—2. this was striker ellen white's second goal. united got one back, then thought they'd scored a second to equalise, but the goal didn't stand. no goal—line technology in the women's game. nick kyrgios will face top seed rafael nadal in the last 16 of the australian open after a five—set win over karen khachanov. the match lasted for four hours and 26

minutes, with kyrgios calling it one of his greatest wins. his meeting with former world number one nadal is highly anticipated — the two have been feuding for some time now. there's more on the bbc sport website, including rugby union and sale sharks' win over the league leaders, exeter. but that's it from me, kate. jane, thank you so much. you can see more on all of today's stories hello. in case you have forgotten what the sun looks like, it will reappear for some of us tomorrow. more of us on monday, but it will come after a spell of rain and then it will turn colder too. but at least a lot of the cloud we have had recently will be out of the way. the cloud is still with us tonight, high pressure though is beginning to move away as we get a big change

in our weather dominated by low pressure for the second half of the weekend and through much if not all of next week. this weather front which is bringing that change will put its rain towards northern ireland and western scotland overnight. ahead of that, plenty of cloud, if you breaks in the cloud here and there, but also some outbreaks of mostly light rain and drizzle. no frost going into the morning. this weather front will take its rain further east across the uk during sunday. it is a cold front, the leading edge of colder air so you can see that moving in behind the rain tomorrow. in that colder air there will be some sunshine coming back but also some showers and some of those turning wintry as we will see in a moment. look how quickly tomorrow the rain is out of the way in northern ireland, pushes across scotland through wales and across england, not reaching the very far south—east though until later in the day. it is behind the rain it will be brightening up, more especially for northern ireland and scotland the lion's share sunday's sunshine but it will turn colder. a cold feel enhanced by a brisk wind, those temperatures will drop off a few degrees once the rain has moved on through so we don't yet

notice that towards the south—east of england but it will feel different out and about by monday morning. coming into the colder air, there will be an area of showers moving right across the uk sunday night but just focusing on northern ireland, northern england and scotland where some of these will be wintry to relatively modest hills, quite low levels in scotland, if few centimetres of snow in places and icy conditions for some of us as well on monday morning on untreated services, so don't get caught out by that. and then on monday there will be further showers around, particularly for the south and west. wintry on the hills of northern britain, some pushing further east on the wind during the day, may be emerging to give longer spells of rain near the south coast. it is going to be a chilly feel two things as well but there will also be some sunshine and catch a shower, not only will it be wintry but they could be some hail and thunder in there as well. as we take a look at the extended forecast through the week, there is a colder feel two things with sunshine and showers. some wintry to start the week

but although it will be a wet and windy at the end of the week, it will be a much milder by then.

hello, this is bbc news. we'll be taking a look at tomorrow morning's papers in a moment. first, the headlines. the death toll from the coronavirus rises to a1,
