welcome to bbc news. the lunar new year holiday has begun in china but it is dampened by drastic measures to prevent the spread of the new virus which has reportedly killed up to 41 people and infected over 800 more. cases are confirmed across asia and the united states and as of the last few hours, in france, too. ten days from now, on this waste ground in wuhan will be a brand—new hospital. the extraordinary pace of building — a sign of how seriously china is taking the threat from the new coronavirus. the prefabricated building will have 1000 beds. it is urgently needed because hospitals in wuhan are overwhelmed with potential cases. the symptoms include cough, fever and breathing problems. a dozen cities have now been quarantined, affecting more

than 30 million people. as you see, nobody here, it is absolutely empty. this should be the busiest time of year for travel and for hotels, but this one in wuhan is deserted. in downing street, borisjohnson hosted a reception to mark chinese new year. the government's emergency cobra committee also met to discuss the risk to the uk, which is considered low. we think that there's a fair chance we may get some cases over time. of course, this depends on whether this continues for a long time, but i think we should definitely see this as a marathon, not a sprint. there are still some key unknowns about this virus. how contagious is it?

early case reports from china suggest people with no symptoms may be able to spread the virus. how deadly is it? so far, around one in four confirmed cases is severe, and most of those recover. it seems less deadly than sars, which killed nearly 800 people worldwide. and what is the source? we're confident the virus jumped from animals to humans, but until the source is pinpointed — perhaps bats or snakes — there is a risk of completely new infections. this is the first image of the coronavirus. work is already under way to develop a vaccine. we can, potentially, move from years to up to 16 weeks to get a vaccine developed and for very early clinical testing, as long as all goes well. for now, the world can only wait and see what impact china's control measures will have on the spread of this virus.

fergus walsh, bbc news. i spoke to a professor of epidemiology at the london school of tropical medicine and he led the sars investigation in 2003. the question with this outbreak, as all new outbreaks, is what is not known. we know a lot of things already about this virus and this outbreak. it is transmitted by close contact, person and hospital workers have been infected, family members. what is not known is if it can spread face—to—face from a cough from one person to another and those are the types of things that need to be understood before effective control measures can be put in place. how do we start to understand that? we have an organisation doing that now, the

world health organization. they have three different groups, clinicians, doctors who are working with patients, epidemiologists are out in the fields and biologists who are looking at the genetic of the violence raqqa virus and they are communicating with the who on a regular basis making it possible for them to understand what is going on formally. sorry to jump in, them to understand what is going on formally. sorry tojump in, but some people are confused on the role of the who, they have decided not to declare a global emergency at this point the people watching have seen it spreading all around the world? yes, andi it spreading all around the world? yes, and i think, i don't want to get the emergency committee which made that decision, confused with the technical scientific committee which makes the recommendations to who. the committee is working, looking at what these people are bringing in and looking at official reports unpublished information and making risk assessments used by

committee such as the emergency committee. the emergency committee yesterday when it met, has decided there was not enough information to be able to make the recommendations they make, which are made based on they make, which are made based on the possibility of this virus causing harm to global health. in other words, they are looking to see if the recommendations that they might make will have an impact on increasing the projection of people in the world, while at the same time not impacting on tourism and travel, trade. their role is entirely different than the role of trying to determine the technical factors that are involved with the outbreak. just one final question, because we are nearly running out of time, but given your experience, i want to bring up the sars virus. what is the one thing you think we could learn from outbreak? the one thing we could learn is the global community

working together, as it is now, will find the answers and begin to control the outbreak in a more effective way every day, as more information comes in. that was david heymann and more details coming out of china about the outbreak all the time. we will bring them to you as we get them here on bbc world news. a powerful earthquake has struck the east of turkey killing 14 people. footage on social media show rescue workers digging through the rubble of collapsed buildings. the earthquake with a mag magnitude 6.8 was felt in neighbouring countries. rescuers carry sui’vivoi’s was felt in neighbouring countries. rescuers carry survivors out from the rubble. the 6.8 magnitude quake sent buildings crashing to the ground and residents rushing into the streets. more than 30 people are feared trapped and more than 500 people have been reported injured. the exact moment the earthquake

abuse of power and obstructing congress. they say he has used foreign policy for his own personal, political gain. mr trump has dismissed the trial as boring. they have reported a recording has emerged of the president reportedly saying he wants the ambassador to ukraine fired. i don't have enough background to give you a response to it at this time. plainly, if the president, at the urging of giuliani 01’ president, at the urging of giuliani or anybody else, if this is additional evidence of his involvement in that effort to smear her, it would certainly corroborate much of what we have heard. but i am not ina much of what we have heard. but i am not in a position yet to analyse that. the senate minority leader chuck schumer has been making the case for witnesses to be allowed to give evidence. the bottom line, we

are seeking the truth at a momentous time in the american republic. it is on the shoulders of four republican senators tojoin on the shoulders of four republican senators to join us on the shoulders of four republican senators tojoin us in demanding it. we have made the argument forcefully. the american people have made the argument forcefully, that they want the truth. wilful republican senators, just four, rise to the occasion, do their duty to the constitution, to their country to seek the truth? republican senator, lindsey graham, has hit back at the democrats claiming if they wanted more witnesses they should have allowed joe biden and his son hunter to be called earlier. the manager said there is not one piece of evidence to suggest that hunter biden did anything wrong. they tried to call hunter biden and people associated

and they were shut out. i was pretty offended by the idea that there is a record here and there isn't one bit of evidence that hunter biden did wrong, when you stop the house from calling hunter biden. that is having your head in the sand. gary o'donoghue explained that what is on the agenda for day four. what they are focusing on today is the second of the two articles of impeachment and that is one that relates to the obstruction of congress. that effectively saying, the president and the white house did not hand over any documents, stood in the way ofa over any documents, stood in the way of a bunch of people giving testimony, prevented as using certain witnesses that we wanted. that is an impeachable offence in its own right. they are making the case. going over the old ground in terms of the detail of the ukrainian business, in order to illustrate what was missing and what is missing from the narrative about that, because of what they call

obstruction of congress. that will go on for the rest of the day and then tomorrow, the president's defence team will kick off their case. they have 24—hour is to do that, in the same way as the democrats did. they will start at 10am, bit earlier tomorrow morning. it is not entirely clear the defence will use the entire 24 hours. they may go shorter. gary o'donoghue there. the foreign secretary dominic raab has described america's refusal to extradite a woman charged with causing a british teenager's death as "a denial ofjustice". harry dunn died after his motorbike collided with a car being driven on the wrong side of the road by anne sacoolas in northamptonshire last august. duncan kennedy's report contains some flash photography. it was last august harry dunn died here and today, the scene was still framed by the caring tributes of those who loved him. anne sacoolas, pictured on her wedding day, is the american woman who's been charged

but say their fight will go on. tonight, the dunns' local mp, the business secretary andrea leadsom, said the family had the full support of borisjohnson in theircampaign. the prime minister is very much on the side of the family in their desire to see justice done for harry and all of us in government are working towards that end. harry's family say they have had to set aside their grieving to pursue this cause and insist they won't be silenced. duncan kennedy, bbc news. stay with us and bbc news. when you panic button on tender as the company begins a crackdown on fake identity. donald trump is now the 45th

northern kenyan is burning. but these are swarms of desert locust, spreading like wildfire across the horn of africa. just one swarm can have more than 200 million insects. these are tiny creatures flying above me. they look harmless, but if you can see, hundreds of millions of them are flying at the same time, them are flying at the same time, the amount of destruction they can cause is unimaginable. this man tells me this is the second invasion of locusts he has witnessed in about 60 years. this time, he has lost nearly all his maize and bean crops. translation: it is painful, we had no rainfor translation: it is painful, we had no rain for several years. when it did finally rein last year, we were so happy. but then these insects have come and destroyed our crop. we have come and destroyed our crop. we have incurred large losses. he says
