in response to the coronavirus outbreak after re—opening following the extended lunar new year break. almost 360 people in the country have now died from the illness — and a special hospital to deal with the crisis is set to open in wuhan at the centre of the outbreak. it was built in just eight days. joining me now from shanghai is our correspondent robin brant. these are quite sharp falls on the market as they open. quite sharp, it is not pretty. none of this is a surprise, it is the resumption of trading for the first time since the chinese lunar new year festivities which has been extended to try to stop the spread of this virus across this country. investors are making it clear what they think about the future for the economy in this country. markets in shanghai, shenzen, down by 9%, of value has been

wiped out in trading this morning. iron ore is down, copper, steel, rubber, cotton, everything is down, except that is, we were looking into one medical company which makes things like gloves, their value has gone up io%. this is despite efforts from the central bank to pump liquidity into the market to send a message of stability. another thing is this new hospital, extraordinary how quickly it has all been done come injust quickly it has all been done come in just eight days. this is a centralised authoritarian rule china at its best. 4000 workers in barely over a week have managed to build this new hospital which will have 1000 beds, another one is due to come in come in will hand with an additional

1600 beds. the public health system is under immense strain as the death toll and the number of cases continues to rise consistently by low double digits every day. who had to remember is the epicentre, the vast majority of people infected with this kind of coronavirus are in wuhan. there are still reports of problems in getting basic medical supplies beyond those specialist hospital centres, gloves, testing kits, disinfectant, things like that. when we spoke a week ago and discussed the concerns of people moving and returning after the chinese lunar new year break and the fact that could contribute to the spread of the virus, is there an indication limits have been put on travel after the break or are people free to move and go back to work? there are limits and conditions. the government is extending the break by various

lengths in various parts of the country. hubei, their holiday continues until february 13, another ten days. in shanghai, schools, businesses, won't open until the end of this week, with varying levels of extension of the holiday across the country, all aimed at either stopping people beginning that mass exodus. remember, it is hundreds of millions of people in china, or at least staggering it so people don't come in a vast swathe. and conditions on travel on buses and trains, it wa nts travel on buses and trains, it wants medical observers to be on hand to check people. there are restrictions, and conditions. eventually these people will have to return to places like shane hayes where they live and work most of the time. thank you very much indeed. police investigating a stabbing attack in london have confirmed

that the suspect had only recently been released from jail after serving a sentence for terrorism—related offences. the suspect — sudesh amman — was shot dead by police after stabbing two people. it isjust moments after a terrorism suspect was shot in broad daylight by undercover officers. they are extremely nervous as he appears to be wearing a suicide vest. another pursuing officer arrives on a motorbike as they retreat. trying to clear the area, while keeping the suspect who is still moving in their sights. within minutes, the whole area is flooded with armed officers.

the man the officers shot was sudesh amman released just days ago halfway through a prison sentence of three years and four months for distributing terrorism propaganda. the home secretary said the government would be laying out even stronger counterterrorism measures. thos measures will build upon actions we have already put in place very swiftly in terms of investing in counter terrorism and the licensing regime around counterterrorism offenders and ending the early release, and in the early release of counterterrorism offenders. it is right that these individuals are kept behind bars. police think amman who had been followed stabbed a man and woman before he shot. i saw the blood and the guy oi'i the floor and other people running. i saw the police coming straight up the hill. as people rushed to help the injured, officers chased him

down to outside boots. armed officers part of a counterterrorism surveillance operation and were following the suspect on foot were in immediate attendance and shot a male suspect dead at the scene. this witness told me he saw the officers opening fire. i heard three shots and i saw him drop and he was alive for a good two or three minutes on the floor but he had a vest. police told everybody we have to move back in case a blast goes off. just over an hour after this all started, police declared it a terrorist—related incident and the main a23 road through south london remains closed tonight. as the scene of the shooting was sealed off for investigation, a knife could be seen lying next to him with his fake suicide vest.

let's brief you on some of the other stories making the news. the contenders to be the democratic party's nominee for the us presidential election have spent a final day campaigning in the state of iowa ahead of monday night's caucuses. the vote marks the start of the state—by—state nominating process to pick the pa rty‘s candidate. the appointment of a new iraqi prime minister hasn't stopped protests across the country. thousands of demonstrators took to the streets of baghdad, and other southern cities, just hours after mohamad allawi was nominated. many carried photographs of allawi with his face crossed out. for the first time ever, cars have been banned from the centre of milan. the ban was enforced from 10am sunday morning until 6pm sunday evening. the city's mayor introduced it as smog levels have been high for several weeks. any driver taking their car into the city was stopped by police.

a united nations flight carrying critically ill patients is expected to leave yemen today heading for jordan and egypt. the un is calling it a major breakthrough after two years of difficult negotiations between the saudi—led coalition — which controls the airspace — and houthi authorities in charge across northern yemen. if all goes as planned, a total of 30 patients and their carers will fly from the international airport in sanaa to amman and cairo over the next few weeks. 0ur chief international correspondent lyse doucet is in sanaa. kidsjust being kids. but some are critically ill and now they have a fighting chance to live. after months waiting in this sanaa hotel. this 13—year—old hopes to be on one of the first un flights to jordan.

her family travelled from a divided city shaken by war. her father tells me she is the smartest girl in her class. but there is something she does not know. cancer consumes her body. i did not want to tell her. because if she knows maybe something... everything will be changed for her. if she stays in yemen, as the doctors say... both legs will be amputated, yes, both legs will be amputated. sometimes she says, "i do not want my father to..."

are you worried about you? what do i say? yes. i love her only. yemen's only cancer hospital. these children aren't on any list to leave. not ali who lost an eye. not this six—year—old. his father says his son cannot sleep at night, he is in so much pain. doctors stopped making lists long ago losing hope there would be a flight. but they don't have what they need to treat patients here. translation: of course this makes doctors angry when we can't give the best treatment. or if a doctor loses his patient, this is so saddening. it is not normal. sometimes i feel depressed. we can't provide some

of the treatments. we don't have equipment because of the blockade. patients should not be affected by the war. we were taken to sanaa international airport. the houthi leader takes the stage, a deserted departures hall, to attack the saudi—led coalition controlling air base stopping civilian flights. there is more than three years of dust in this hall. the saudis proposed a way out, diverted civilian flights to another airport to search them. for sa naa, sovereignty trumps everything. translation: this airport has its own security procedures. that means civilian aeroplanes cannot carry weapons. there are satellites and they have their spies in the ground. and they know if there is any movement in sanaa airport, they can prove it with photos. an airport can seem so ordinary.

but for so many yemenis it has come to mean so much. students can't fly home. families are divided. patients can't get medical care abroad. for the critically ill, the airport blockade has been nothing less than life or death. a city of the dead. this boy's father died waiting for liver treatment, waiting for a flight. he tends his grave every week. translation: for two years, they kept promising he would travel on a un flight. we had everything ready. this war has destroyed everything. many patients have died, just like my father.

a mercy in this war. these first flights a gesture for warring sides. for some, too late. for many others, a glimpse of hope. lyse doucet, bbc news, sanaa. stay with us on bbc news. still to come. the first world war film 1917 wins seven british acadamy film awards, including best film. this is the moment that millions in iran have been waiting for. after his long years in exile, the first hesitant steps of ayatollah khomeini on iranian soil. south africa's white government offered its black opponents concessions unparalleled in the history of the party. and nelson mandela mondello will be set free unconditionally.

kansas city chiefs have won america's 2020 superbowl — the sporting event billed as the greatest show on earth. they beat the san francisco forty niners in miami, florida. the game also included half—time performances byjennifer lopez and shakira. we have chief fans kj and jeff lady in kansas city and joe leonor who is founder of the niner empire. it is a huge fanclub for the 49ers with more than 150 chapters around the world. he was at a pool party in miami and now is back in his hotel room. let us speak to the victors first, what does this mean, you have been waiting 50 years for this. it is amazing. we have been waiting a long time, and it is so exciting. incredible.

so excited they are speechless or it could be the technology! hello, it must be quite heartbreaking to see your rivals are celebrating so exuberantly. yes, just hearing them celebrating hurts. with the 49ers, nobody expected us to be here this year and we were here at this super bowl, it is still at this super bowl, it is still a young team but we will be back. do you think the others played the better game, in fairness? imean, the better game, in fairness? i mean, they came out... yes. i am not going to make excuses. magnanimous, gracious in defeat is always a good quality. let

us is always a good quality. let us talk a little bit about patrick mahomes. what do you quys patrick mahomes. what do you guys make of him? i tell you. the kid guys make of him? itell you. the kid is guys make of him? i tell you. the kid is smart. he can do everything. he can do everything. he isa he can do everything. he is a leader, he is a talent. they respond to him and that is so important, it is amazing. i have to bring up something. i gather that you sang in the half—time show 35 years ago! tell us about that? it was super bowl xx, i actually performed the finale song. it was for the half—time show. but i was impressed watching

shaqiri tonight. —— shakira. and you are a dancer, what was your verdict on the half—time performance this time? i would say they were away professional, it has come a long way. 0k. kansas city chiefs fans, thank you very much. and thank you. sorry about the line there. they are very happy indeed. we are! chiefs! prince william says it simply can't be right that all 20 of the acting nominees at sunday night's british academy awards were white. speaking as the organisation's president, he stressed that

a review was being carried out to make sure that opportunities are available for everyone. the acting prizes went to joaquim phoenix forjoker, renee zellweger forjudy, brad pitt for once upon a time in hollywood, and laura dern for marriage story. but it was the first world war epic 1917 that took home the most awards. 0ur arts editor will gompertz reports the ceremony faced criticism for a lack of diversity among its nominees. this is the moment that millions in iran it is the british film business' big night out. legendary actors and rising stars gather alongside hollywood royalty and british royalty for the baftas. as they make their way up into the royal albert hall, they do so under a cloud of controversy about lack of diversity among the nominees for tonight's awards, an issue bound to come up during the night's event. and so it did whenjoaquim phoenix took the stage to collect the best actor award for his performance injoker.

i think we send a clear message to people of colour that you are not welcome here. we have to really do the hard work to truly understand systemic racism. i think it is the obligation of the people that have created and perpetuate and benefit from a system of oppression to be the ones to dismantle it, so, that is on us. the subject of diversity arose again when rebel wilson made thisjoke... about the all—male best director line—up... i do not think i could do what they do. honestly, i do not have the balls! and the category was won by sam mendes for 1917, winning seven baftas in all including prestigious best film. it was a wonderful night, thank you very much. the best actress went to renee zellweger for her portrayal of judy garland.

laura dern won for best supporting actress for playing a super—smart lawyer in marriage story. best supporting actor went to brad pitt who was absent but wrote a speech that margot robbie read out on his behalf. hey, britain, heard you just became single, welcome to the club. he said he will name this harry because he is excited about bringing it back to the states. prince william, bafta's president might have found it funny. but when it came his time to speak he was in no mood forjoking. in 2020, and not for the first time in the last few years, we find ourselves talking again about the need to do more to bring more diversity in the sector, the awards process. that simply cannot be right in this day and age. a serious point to end

a night of celebration. and tell me what you think about our talking point today. let us know your thoughts — use the hashtag #bbcthebriefing. i was asking if you are awarding the greatest films of all time, which would be on your list? angela says, too many to list. 0thers your list? angela says, too many to list. others of you have been in touch. ian says, the categories seem to be all wrong these days. politics seems to be more important than the actual film seems to be more important than the actualfilm or seems to be more important than the actual film or television show, surely it should be about the show, film, actor, actress or director, over whether they are diverse or not. why notjoin in the conversation?
