The chinese authorities are taking drastic action to try to stop the spread of the new corona virus. Theyve imposed a travel shutdown on several cities, including wuhan, where the virus was first discovered. 25 people have been killed by the virus in china thats up from 18 in the past few hours. But the World Health Organisation has said it is not yet a Global Health emergency. John sudworth reports from beijing. This is the moment a city of 11 Million People was effectively shut off. Pa ramilita ry police guarding the station, as all departing trains are cancelled. In the hospitals, medical staff in full bodysuits are treating hundreds of infected patients. While images on social media appear to show a system struggling to cope. Empty shelves in the shops and scuffles over food. We spoke to one british man now stuck inside wuhan. Its a very surreal feeling. You know, knowing especially that if you go outside, there is potential to catch such a deadly virus. And when you look outside the window, whats the atmosphere like . Does it feel like a city under a blanket of fear . Oh, yeah, 100 , 100 . Behind me, if you saw the street at night time where i normally live, its a very vibrant street, lots of restaurants, and its open until 2am and chinese families come and theyre celebrating, but if i show you out there now, its dead. On chinas main evening news, the lead item . A new year banquet for senior officials. President xijingping makes no mention of the crisis. He but the facemasks on display at this beijing station are proof the public is well aware of the risks. Yeah, a little worried, because, you know, i. Youre wearing your mask . Yeah, a mask. And this one. Goggles as well. Are you worried about the virus . No, because i believe in my country and my government. You believe in your government . Yes. This is an epidemiologists nightmare how do you control the spread of a dangerous virus during the Biggest Movement of people on the planet . Tens of millions travelling every day for at least a fortnight, and the real question is whether the closure of the city of wuhan comes far too late to make a difference. Alongside the Public Health announcements, there are signs of censorship and control, and questions are being asked whether more might have been done sooner. John sudworth, bbc news, beijing. So what do we know about how the coronavirus is spreading . At least one death in china has come from outside the centre of the outbreak wuhan where the movements of its 11 million residents are severely restricted. Theres a similar lockdown on another eight and a half Million People, in the cities of huanggang and erzhou, 70 kilometres away. Wuhans high speed rail links have been shut off from most of chinas most important cities leaving train stations empty and residents in limbo. Jao yin fung from the bbc Chinese Service gave us this update on whats been happening in wuhan itself. On chinese social media, were seeing videos coming out of wuhan. You see the streets are very empty, you dont see any public buses now because Public Transportation has been shut down, but two places are very crowded. One is hospitals. We see overcrowded hospitals with people lining up to get test results for family members, and there are media reports that test kits and protection gear are in shortage at the moment. The other place is the grocery market. People in wuhan are lining up to buy groceries because theyre worried that supplies for the city are not going to last for a long time given the current shutdown. And chinese citizens are asking very tough questions online, mostly boiling down to one could we have dealt with this better . Thomas friedman is the president of resolve to save lives which focuses on preventing epidemics and the former director of americas centers to prevent disease control. He explains how this coronavirus differs to previous viruses like sars. This is a Novel Coronavirus that, you know, was just released several weeks ago, and theres still a lot we dont know. The two main things we need to understand are how infectious is it and how deadly is it, and for those two things, were going to need a lot more of the epidemiology, a lot more to tell us what the patterns are. Healthcare workers have become impacted. How did that occur . Patients have died. How many have become infected . We know the number of cases that have been reported, but how many have been tested . How many contacts are positive for each case . Theres so much we know. At this point, there are only a few things we can say for certain. One of them is that its a newly recognised virus. We have never known this virus before. Second is that its causing severe illness and death. The third is that its spreading from person to person. So those are not good things. But we dont yet know how severe it is, and for that reason, precautionary measures are quite important, protection of healthcare workers quite important, and learning more as quickly as possible, and sharing that information openly, also critically important. Just reading your latest piece, you make it clear that, on what the World Health Organization has already indicated, there are strong suggestions this virus could potentially spread widely and for a long time. Do you feel the measures that need to be taken are being taken . At this point, there are several things that need to happen. Widespread testing of people at risk in wuhan and other areas of china which may have been exposed. Careful protection of healthcare workers, because both sars and mers, another coronavirus, spread widely in healthcare facilities. And finding out more about why this is spreading, what the risk factors are, so that we can reduce that risk. You make a point, i know it is a quote, that we are outnumbered by microbes by billions to one. It is their numbers against however smart we can be. There are quite simple, though, Infection Control strategies that i think a lot of us dont necessarily think of. One of the things thats not done nearly enough is to wash your hands. Hand washing is very effective at reducing a wide variety of viral and some bacterial infections. So washing your hands every time before you eat, regularly throughout the day, any time after you have gone to the bathroom, is very important and really cuts down everything from School Absenteeism to the risk of serious illness. In addition, cough hygiene, so covering your mouth and nose when you cough or sneeze, with a tissue or with your sleeve, preferably not with your hand, is a good way to reduce the spread of infection. In many parts of asia, people who are not feeling well wear facemasks, and some very rigourous studies that have been done in the us suggest that that is moderately effective at reducing the risk to other people. The us senate has been hearing a second day of arguments in the impeachment trial of President Trump. Democrats are making the case that he abused his power by using American Military aid to pressure ukraine into helping him discredit his political rivaljoe biden. A key point of contention is whether witnesses and more documents should be allowed. Heres the top democrat in the Senate Making the case. The same republicans are saying that they heard nothing new, but these republicans voted nine times on tuesday against amendments to ensure new witnesses and new documents to come before the senate. Let me repeat the same republicans saying they heard nothing new just voted nine times on tuesday to hear nothing new. The bbcs Chris Buckler is in washington he told me the latest. Yeah, inside the senate, the democrats are putting out their case against this first charge against President Trump that he abused his power and his position as president. You get the impression while this is all happening in a pretty staid environment inside the senate chamber, behind the scenes theres plenty of conversations going on, with republicans and democrats you talking about their strategy is going to be in this and whether or not witnesses will come forward. Thats something theyre not just talking about, its also President Trump as well, because democrats basically want to introduce as much new information as they can. Theyd like to have people subpoenaed and brought to the chamber in order to give evidence, not least the likes of the former National Security adviser to President Trump, john bolton, who left under a bit of a cloud and who apparently made a number of comments about President Trumps behaviour as regards to this push for ukraine to launch investigations into his political rivals. You in return, there are suggestions republicans would like to have the likes of hunter biden come to give evidence. That is the son ofjoe biden, someone who had business dealings in the ukraine and frankly was making a huge amount of money there, and President Trump has made unfounded allegations time and time again that there may have been corruption involved in all of that. Hes denied that, but hes certainly picked up on this idea of a witness trade of some description. Hes tweeted today, the democrats dont want a witness trade because shifty schiff. , may thats adam schiff, the lead impeachment manager,. The bidens, the fake whistleblower, the second whistleblower, the so called informer and many other democrat disasters would be a big problem for them. Its the president striking back, and actually hes been doing what he can outside of the chamber to disparage these whole proceedings, even describing them as boring. The United States is tightening visa restrictions to stamp out so called birth tourism. From friday pregnant women applying for visitor visas will have to prove they have a reason for going to the country, other than giving birth, as anyone born in america gets citizenship. Sergio gonzales is Deputy Director of the immigration hub, and former senior policy advisor to us senator kamala harris. He explained how the Trump Administration seems to be going to Great Lengths to prevent immigration. Unfortunately weve seen a lot of hideous attacks by this administration to use any tool they can to reduce immigration, including those seeking asylum at our southern border and unfortunately in that agenda they really implemented some of the most terrible policies that are discriminatory in nature, and this is one of the worst examples of that. Essentially what the new regulation will do is allow the administration to deny entry to women and girls at consular offices for tourism and business if they are not presumed to be pregnant. Essentially what this will mean is the profiling of womens bodies from entering the United States if a consular officer believes that woman is pregnant. And it is possible, i know we are hearing from some people, that if a woman is deemed to be overweight, she might have to prove that she is not pregnant . Exactly. In a lot of instances, this is going to be a humiliating prospect almost something you would think of in a dystopian future for women, who have to go into an office in a public setting and have an officer who has no idea who this woman is believed that based on that womans size, based on her body, she might be pregnant and then make that woman prove potentially through some sort of test in that setting that she is indeed not pregnant. As i said before, this administration has really implemented some of the most draconian immigration policies, anti immigrant policies, i think that weve seen in our nations history, whether or not were need me separating kids from their families. This is another disturbing example that isntjust about immigrant rights but also about womens rights and womens rights to their own bodies. Do we know how consular officials feel about having to police reproduction and womens bodies in general . You you know, we dont know that but we do know that this is certainly not. For people who are hired to be consular officers, they are not medical professionals. This is not an area of their expertise, their background or training. To turn them into policemen basically around womens bodies and what amounts to a health issue is very disturbing, and i think can have some disastrous consequences.

The us senate has been hearing a second day of arguments israels Prime Minister has vowed that there will not be another holocaust. Benjamin netanyahu was speaking injerusalem, as World Leaders and Holocaust Survivors marked 75 years since the liberation of auschwitz. Israeli Officials Say the event is the Biggest International gathering in the countrys history. Our middle east correspondent, orla guerin reports. Frail but determined, Holocaust Survivors coming to honour those who perished, lighting a memorial flame for the six million jews annihilated by the nazis. Among those gathered on jeruselams mount of rememberance, heads of state, Prime Ministers and princes pledging to combat an enduring threat the dark shadow of anti semitism. And here is its incomprehensible expression. Auschwitz, the gates of hell. The nazis killed more than a Million People in this one camp before it was liberated by the red army. For many, auschwitz is the ultimate symbol of evil. It is certainly that. Israels Prime Minister used this platform to call for Global Action against iran, saying it wanted to develop a Nuclear Weapon to destroy the jewish state. They threaten the peace and security of everyone in the middle east and everyone beyond. I call on all governments to join the vital effort of confronting iran. The music was a haunting echo from the past. It was composed by viktor ullmann. He himself was sent to auschwitz and died in the gas chambers. From prince charles, whose grandmother, princess alice, saved a jewish family, a call for mutual understanding. The lessons of the holocaust are searingly relevant to this day. On this day, in this place, and in memory of the millions who perished in the shoah, let us recommit ourselves to tolerance and respect. As this anniversary is marked here at yad vashem, jewish officials want to send an urgent warning. They say violent acts of anti semitism are on the rise and thejewish life is once again under threat in europe. They insist the worlds duty to remember is more crucial now than ever. Still bearing witness at almost 90 years old, holocaust survivor naftali deutsch. Recites jewish prayer he recited the mourners prayer, the kaddish. The vow here today, never again. Orla guerin, bbc news, jerusalem. Climate change, global tensions the world does seem to be in a more perilous state than before. And scientists behind the so called doomsday clock, say thats no false impression. The time has moved tojust 100 seconds to midnight after experts altered the clock due to the state of world affairs. The clock now stands at its closest to doomsday since it began ticking in 1947. Rachel bronson is president and ceo of the bulletin of atomic scientists and she told me why they thought it was necessary to move it closer to midnight we are very concerned. Were moving the clock towards midnight. Its the closest its ever been. Were very concerned about the issues of nuclear risk and climate change, both trending in the wrong direction, in terms of safety and security. But theres a really important segue from your last guest to this discussion, which is one of the things we call out, are not only are those trends getting worse, but the International Capacity to deal with these major global issues is crumbling, and were really concerned about our ability to handle these big challenges. And the previous conversation on the coronavirus fits right into it, actually that theyre struggling with the same kind of issues. So what needs to change, to take the clock further from midnight . So we need to look at the things we can do independently, the things we can do on nuclear issues, like continue to advocate for a continuation of the arms control agreement new start, reduce the kinds of investments that are going into Nuclear Weapons. But what broadly, across all of them is we need to reengage at the International Level to find new mechanisms to reduce these threat. These are big global challenges, that require big global solutions. And instead, what were seeing is countries, led by the United States, but other countries as well, walking away from international agreements, International Solutions to these big challenges. And thats one thing that we really can advocate for, here in the us and globally. The clock is obviously a visual representation of how concerned you are, how concerned we should all be. You must be aware a lot of people, especially young people, are very, very anxious about climate. A lot of people feeling, well, there isnt much i can do about this. So are you just ramping up peoples concerns, actually, without offering a way through . No, i dont think thats true at all. I think what were doing is reflecting that anxiety out there, and what were trying to show is that youre not alone in thinking that things are getting worse, and that we need urgent attention to it. In fact, our leading science and Security Experts fully agree with that. And what were trying to say, actually, is to point out, and we do in our report, that what were seeing in the climate space, and the publics engagement around it, and the kind of youth movements that were seeing pushing this issue into the political discussion and into political platforms globally, is having an effect. We dont think that were responding as quickly as we need to be, but we do call that out as a bright spot, and we would like to see the same thing happen in the nuclear space, as well. So hopefully what this does is for those who are out there, you know, on the streets, wondering if anyones listening were listening. We see that, and were supporting those efforts, because we agree. Things are not getting better, and our leaders arent taking care of us the way we thought that they were. Two years ago a British Museum made a Public Appeal asking anyone who owned an early ceramic work by the artist Grayson Perry to make contact. The response led to hundreds of long lost pieces being identified, 80 of which have been assembled for a special exhibition. The Turner Prize Winning artist, who describes himself as a transvestite potter gave our arts editor, Will Gompertz, a guided tour of his formative work. It must be quite moving to come and look at your past work like this. Thats true, its thats the first. When i came in here, i sort of drew breath, because suddenly i was confronted by all these works, that i hadnt seen many of them for decades and decades, since i sold them. And yeah, im looking at the young me, and as im now post thera py, im looking at him with compassion. You know, i was very angry and, you know, at the mercy of the internal winds of my emotional weather, lets just say. And people thought in this early work that it was deliberately, ironically bad. But no i have to tell you, i am genuinely inept. In this exhibition is literally the first plate that i made in evening classes in 1983, and i put it in an exhibition. You know, the fact that i embraced my own ineptitude was very important. It took until i won the turner prize for people to sort of drop their snobbery about it being just a load of pots. You know, i was amazed at how long that went on. And i thought, thats funny. You know, you can bring a urinal or a shark into an art gallery and its this amazing, you know, brave conceptual move. But, if you brought a pot into an art gallery, somehow it was sort of the pretentious next door neighbour of art. What comes through these pots and plates, grayson, time and time and time again, is the sense of humour running right through. I think that humour is often dismissed as light and entertaining, when in fact i think its one of the most profound qualities that we possess as human beings the ability to laugh and to make jokes. Ive always used humour, and as i get older, i see it more, and im more moved by it now, you know, the fact we have this amazing ability to reframe the tragedy and struggles and toils of life. And, you know, the darker it is, the more we laugh, quite often. You know, we laugh in the face of death. Our arts editor Will Gompertz talking to Grayson Perry. Much more for you at any time on our website and on twitter. Hello. Six hours of sunshine in sheffield on thursday. Much of the uk couldnt even manage six seconds of blue sky, with scenes like this. There are weather changes on the way over the weekend, and that will shake things up a bit, but until then, plenty of cloud. The big picture shows High Pressure giving way to this weather front, which will spread rain southwards across the uk during sunday, wind picking up as well. Behind that, skies will eventually turn brighter, but itll feel colder into the start of next week. But not looking at any frost, certainly not widespread, to start friday. Plenty of cloud, damp, drizzly, misty and foggy in places too. Particularly across parts of england and wales, poor visibility. Now, some rain near the north coast of northern ireland, south west scotland, pushing up across the western side of scotland during the day. Increasing cloud in the afternoon in north east scotland. Until then, some sunny spells. Still some brighter breaks in north east england, it brightens up a bit in northern ireland, and perhaps some glimmers of sunshine the Channel Islands and far south coast of england. Temperatures are close to average for the time of year, if not a bit above in some spots. Going through the night and into saturday morning, still cloudy, damp, drizzly, misty, foggy in places. But all of that cloud keeping temperatures up, so again, frost free to start the weekend. This weather front getting a bit closer on saturday. But really, for most of us, its as you were, with lots of cloud around, again misty, murky start, damp and drizzly in places. There are signs of a zone of brighter skies running up across eastern parts of england during saturday. But theres showers coming in towards western parts of england and wales, maybe one or two later to northern ireland, and rain gathering on that weather front we saw towards north west scotland. It is this which eventually moves south saturday night into sunday, taking some rain. With that, the winds pick up, but notice the blues following on behind. Yes, brighter skies, but feeling colder. So this is how sunday is looking. Looks like therell be a spell of rain for all of us at some stage in the day, but the further south and east you are, in particular, thatll be later in the day as the front gradually moves across the uk. Now, behind it, you get the brighter skies. May see a few showers, wintry on hills in that colder air mass, particularly in scotland, as those temperatures drop away behind the weather front, though still mild for another day towards the south east of england as that rain moves in. And a big change in the weather into the start of next week. Itll be wetter, windier, itll feel colder for a time, as low pressure takes over. Just a flavour of what we might expect. Inevitably itll change, getting closer to these days, but it is a big change in the weather. Are there are this is bbc news, the headlines authorities in china have imposed strict travel restrictions in more cities across the province of hubei, which is at the centre of an outbreak of a new coronavirus thats killed twenty five people.
