welcome to newsday, reporting live from singapore. i'm karishma vaswani. the headlines: the evidence is compelling, say scientists. covid—19 did start in an animal market in china's wuhan province. teetering on the brink of a world recession — the stark warning from the international monetary fund. russia says it will withdraw from the international space station and build its own, ending decades of cooperation with the us and other countries. and england thrash sweden 4—0 in the women's euros semifinal. next stop the final, and the chance to win

their first ever major tournament. welcome to bbc news, broadcasting to viewers in the uk and around the world. our top story for you today: scientists say there's compelling evidence that a market selling live animals in the chinese city of wuhan was the early epicentre of the covid—19 pandemic. it's a significant contribution to what's always been the dominant theory — that the outbreak began with the coronavirus spreading from animals to humans at the so—called �*wet market'. this is the seafood wholesale market in wuhan. one of the studies just published in the journal science says genetic information suggests there were two crossover events where animals infected humans in late 2019. a second study — also in science —

shows the earliest known cases in the city were clustered, around that market. i spoke to dr michael worobey, one of the lead authors of that study — and professor of ecology and evolutionary biology at the university of arizona. he took us through the research that was involved in coming to these conclusions. we published two papers in science magazine today. the first as you mentioned places the wuhan market at the epicentre of this pandemic, very, very clearly and on that one, we relied on data that had been collected as part of that who mission that was joint with china but you mentioned and that data has been around for about a year, but the location information, the residences of the earliest 174 cases back in

december of 2019, were not really easily available and the first thing we did was work out where most of those were and with that, we were off to the races and we could see this exquisite signal that they were clustered very near to and surrounding the market in a way that was statistically off the charts, very clear that these cases were centred on and diffusing into the local community from the earliest time point from there. what we are trying to do is figure out, as scientists, what happened, so that we can figure out how we can prevent it from happening again, so rather than getting into this game of pointing fingers, which the world has seen more than enough off, and frankly i would like these papers to be the endpoint of that exercise, i want to know what happened and what we can do to prevent the next one

from going down the same lines and what we know now is that the wildlife trade in china is at the centre of this outbreak and so yeah, absolutely, let's figure out what we can do to stop that from happening again and there is plenty we can do. indeed, professor, and just briefly, talk us through some of the things we should be looking to do in the event of another outbreak.— looking to do in the event of another outbreak. ok, so one of the things _ another outbreak. ok, so one of the things that _ another outbreak. ok, so one of the things that is _ another outbreak. ok, so one of the things that is amazing, - the things that is amazing, actually is how quickly we identified this up and chinese doctors, by december 27, identified this up and chinese doctors, by december27, had worked out this was a new thing and what our paper shows is that only it probablyjumped into humans may be in late november so this is a very quick connecting of the dots when you consider how few people were infected early on so we need to detect weird

cases of pneumonia that can't be explained by the things that we already know cause pneumonia very quickly and we need to take those people, take samples from them and molecularly characterise them which we can do in a day now and find out, is this a new coronavirus, new flu virus? all of that, this pandemic has shown we can do but we didn't do a good job in terms of moving through the paces as quickly as we could to public health measures that actually stopped it from becoming a pandemic, but i'm encouraged that we can do a lot at, and a virus like this, we could stop next time. that was one of the lead authors of that study and professor of ecology and evolutionary biology at the university of arizona. in other top stories for you today: the worst recession in half a century.

that's the warning from the international monetary fund. in its world economic outlook it predicts global growth will be slower than previously forecast. the funds chief economist said higher interest rates to curb inflation are making the risk factors much worse. we're expecting inflation to be more of a short—lived problem than it proved to be, and if the standard response when you get elevated energy price would be to say, look, there's not much the central banks can do to control the price of oil. therefore, if it's going to be transitory, let's just wait. there's not much we can do. but what we realise that it's not just that, as ijust explained. it's a combination of factors — sort of the perfect storm for inflation. we can supply disruption, strong demand, and on top of that, and energy price shock. all of these things are pushing inflation outside of the comfort zone.

and we'll have more on that story for you in about 20 minutes time on asia business report, with a special report from our business reporter samira husain — so do tune in to that. let's take a look at some other stories in the headlines. the white house says china has only escalated tensions by its sharp rhetoric against a proposed visit to taiwan by the speaker of the us house of representatives, nancy pelosi. beijing said on monday it had issued forceful warnings to the biden administration over the plans. the sharp diplomatic exchange comes as president biden prepares to speak by phone with his chinese counterpart, xijinping, in the coming days. police in the democratic republic of congo say at least 15 people, including three peacekeepers, have been killed during demonstrations against the united nations in the eastern city of butembo. the demonstrators are demanding the departure of the country's un peacekeeping mission, which they say has failed to restore peace. japan has executed the man who killed seven people

during an attack in tokyo in 2008. tomohiro kato drove a truck into pedestrians before stabbing a number of others. he was charged eight years ago, and is the first person to be executed this year injapan — one of the few developed countries which still use the death penalty. in the uk, the latest tv debate between the two candidates that want to be prime minister — liz truss and rishi sunak — was cancelled, after the presenter fainted on air. the sun and talktv debate, hosted byjournalist kate mccann, was abruptly halted around halfway through after a loud crash was heard. talktv said mccann was "fine" but the channel had been given medical advice not to continue. to russia now — which has said it will withdraw from the international space station after 2024, ending two decades of cooperation with the united states and other countries. washington has described the announcement as unfortunate. the head of the russian space agency said moscow would instead build its

own orbiting station. here is the chief of the agency speaking to president vladimir putin earlier. translation: undoubtedly, we will fulfil all our obligations towards our partners but the decision on leaving the station after the year 2024 has been made. i think that by that time we will start forming a russian orbital station. i spoke to retired canadian astronaut chris hadfield, whose 20 year career in space saw him command the international space station and help build the russian space station mir, to ask what he made of the russian announcement. you know, if you actually listen to what he just said, it's that after 2024, we are going to leave the international space station. you know, that's at least over two years away. everybody is going to leave the space station sometime after 2024 so i said very much, the man has only been on the job for 11

days now so it's a good negotiating ploy but i wouldn't put too much weight into it. there is all sorts of legal things that would have to happen but it gives a lot of manoeuvring and sort of negotiating room as they look at what they want to do forward on the space station.— on the space station. what do ou on the space station. what do you think _ on the space station. what do you think is — on the space station. what do you think is behind _ on the space station. what do you think is behind this - you think is behind this statement? what are they trying to achieve?— to achieve? every nation, including _ to achieve? every nation, including the _ to achieve? every nation, including the united - to achieve? every nation, | including the united states to achieve? every nation, - including the united states and all the other 13 or 14 partners of the station, they have to regularly decide, as their politics change, how they are going to participate in international station, what level they are going contribute, what their returns are going to be and so each country has their own national agenda so everyone wants to be in a strong bargaining position and i think by saying something sort of outlandish by this, it just improves the russian bargaining position, so i think it makes sense if you are playing chess, it is kind of a

good early move.— playing chess, it is kind of a good early move. chris, you were in space _ good early move. chris, you were in space at _ good early move. chris, you were in space at a _ good early move. chris, you were in space at a time - good early move. chris, you were in space at a time and | were in space at a time and arguably relations between the russians and the international community was better. just talk us through what it was like being in one of these international space missions, astronauts from all over the world, us and russia, working together. i world, us and russia, working touether. ., world, us and russia, working to . ether. . ., , world, us and russia, working touether. . ., ., together. i mean, i was also a cold war _ together. i mean, i was also a cold war pilot _ together. i mean, i was also a cold war pilot intercepting - cold war pilot intercepting soviet bombers as a combat cold war pilot so i've seen politics come and go and positions shift. i helped build the russian space station mir and i was nasa's director of operations in russia for a few years. it's never been easy, you know? we were participating during the devaluation of the rouble and during the crash of 2008 and there is always conflict but there is always cooperation and just on friday, samantha christopher eddie did a spacewalk with a cosmonaut

just this past week on the space station and it's the crown jewel of their programme. it's the biggest and best thing that they have in their entire space programme so it's never been easy, international cooperation is difficult but we're still doing it on a daily basis and none that has changed. i5 basis and none that has changed-— basis and none that has chanced. , ., , . changed. is it more difficult now, changed. is it more difficult now. do _ changed. is it more difficult now. do you _ changed. is it more difficult now, do you think, - changed. is it more difficult now, do you think, given i changed. is it more difficultl now, do you think, given the current tensions the world is seeing? current tensions the world is seeinu ? ., , ., , seeing? the world is a tense lace. seeing? the world is a tense place- and — seeing? the world is a tense place- and i _ seeing? the world is a tense place. and i think— seeing? the world is a tense place. and i think when - seeing? the world is a tense l place. and i think when russia invaded crimea several years ago, that caused a lot of tension. obviously the invasion of ukraine is a traumatic and horrific thing for so many different players, specifically for everyone in ukraine and for the russian people for a long time as well. but of course adds to the tension in so many different fields but meanwhile, there are seven people up on there are seven people up on the space station running 200

experiments, working very closely together, being supported by emission controls all around the world on a 24—hour basis, seven days a week and we have been doing it for almost three decades now, including mir, so i don't want to overreact to a couple of sentences that somebody said in moscow earlier today. chris astronaut speaking to us earlier. you're watching newsday on the bbc. still to come on the programme: england beat sweden 4—0 in the women's euros semifinal, giving them a chance to win a first ever major women's tournament. cheering. the us space agency, nasa, has ordered an investigation,

after confirmation today that astronauts were cleared to fly while drunk. this the last foot patrol in south armagh, once an everyday part of the soldier's lot, drudgery and danger, now no more after almost four decades. if one is on one's own, - in a private house, not doing any harm to anyone, i don't. really see why all these people should wander in and say, - "you're doing something wrong". six rare white lion cubs on the prowl at a worcestershire wildlife park, and have already been met with a roar of approval from visitors. they are lovely and sweet, yeah, they're cute. this is newsday on the bbc. i'm karishma vaswani in singapore. our headlines: scientists find "compelling evidence" that covid—19 started in wuhan's seafood and wildlife

market, casting more doubt on claims it came from a lab. the international monetary fund warns that the world could be teetering on the brink of the worst recession for half a century. the us government estimates it may need nearly $7 billion to deal with the monkeypox outbreak in the united states, the washington post has reported. the funding estimate was part of a memo to president biden outlining a series of options. the news comes days after the world health organization declared the monkeypox outbreak a global health emergency. nearly 70 countries, in which the viral disease is not endemic, have reported outbreaks. well over 200 cases of the virus have already been reported in chicago. a charity administering a vaccine there, complained that there wasn't enough supply. we had over 200 people lined up

around the building, we only have 100 doses of the vaccine so that the same today. we had a lot of people come, a lot of people line up early, unfortunately had to turn some people away because we only have 100 to give out. to australia now, where the issue of diversity in politics is back in the spotlight, as the new federal parliament met for the first time this week since may's election. this parliament is the most racially and cuturally diverse in australia's history, with a record number of female and non—white mps. but many diversity advocates say it still doesn't come close to reflecting the make—up of the population. earlier i spoke to dai le who has recently been elected to the australian house of representatives, i asked her if things are changing in australia with diversity in politics. look, it has been such an honour and such a humbling experience, really, to be elected for our area called

fowler, one of the most culturally diverse electorates in the country. yes, we have seen some more women elected, more people elected of culturally diverse backgrounds to be elected to our parliament at this 47th parliament, that said, though, istill think at this 47th parliament, that said, though, i still think we are still a long way off in terms of having diversity of, notjust terms of having diversity of, not just cultural diversity terms of having diversity of, notjust cultural diversity or diversity of perspectives as well represented in our australian federal parliament. but look, this is a first step. we have not reached a tipping point yet, not to put it that way. sometimes things are done just to show. a mean i got elect it as an independent from the community. i am not backed ijy the community. i am not backed by any major parties and sometimes parties will bring a show that they are diverse but that doesn't necessarily mean that they are in terms of diversity of perspective and really getting the diversity

representation at the leadership level. so you can have just a show but it doesn't mean that... so, yeah.- have just a show but it doesn't mean that... so, yeah. yeah. it is interesting _ mean that... so, yeah. yeah. it is interesting that _ mean that... so, yeah. yeah. it is interesting that you - mean that... so, yeah. yeah. it is interesting that you are - is interesting that you are talking about the diversity of the spec of, the diversity of thought, and i think for the benefit of our viewers, just to explain how you got to where you are, because yourjourney started and rather remarkably when you came to australia for the first time as a vietnamese refugee. the first time as a vietnamese refu~ee. ., v , refugee. that's right, my family and _ refugee. that's right, my family and escaped - refugee. that's right, my . family and escaped war-torn family and escaped war—torn vietnam at the end of the war in 19 75. i was a young girl, asa in 19 75. i was a young girl, as a seven—year—old, and we spent, my single parent, mother, we escaped by boat, got resettled in australia, spent a few years in refugee camps in

southeast asia and then we accepted a full resettlement in australia in december 1979. so the unhcr, back in those days with the vietnamese exodus, made a very important role in processing people in camps in south east asia so we were very lucky to be given the opportunity to be resettled in australia and we arrived here with literally one single suitcase and none of us could speak english. we probably were able to say hello, how are you. it's just amazing stuff listening to your life story there and they don't want to take away from that but ijust want to ask you, what do you think is holding more diversity backin think is holding more diversity back in australian politics? look, i don't know what it's like in the uk but certainly here, people of non—english speaking backgrounds are very reluctant to step into leadership roles, because obviously there is going to be a lot of demands in terms of time spent, in terms of

networking, in terms of playing the office politics or learning how to navigate office politics in addition to understanding how to navigate the political sphere if that's what people want to do, so there's a lot of reluctance especially for women as well. they have to choose between raising a family, looking afterfamilies between raising a family, looking after families because thatis looking after families because that is mainly people of predominantly ethnic backgrounds tend to prioritise the family's needs more than anything and so that has kept them back in terms of stepping into leadership roles. so when we talk about diversity... that paul is not there. in addition, the system is also actually quite, there is that subtle, what we call the glass ceiling, so they are both sides, it is notjust so they are both sides, it is not just one so they are both sides, it is notjust one or the other. firefighters say they're finally starting to making

progress in their attempts to control a wildfire that has threatened yosemite national park in california. thousands of people have been forced from their homes as the hot, dry weather fuelled the flames. there aren't many cars going in this direction locals have been ordered to evacuate from plumes of smoke and raging fires beneath them. deeper into the forest and people's homes are on the edge. left by their owners, the difference between these houses surviving and not our men like oil. it these houses surviving and not our men like oil.— our men like oil. if you look throu~h our men like oil. if you look through these _ our men like oil. if you look through these trees - our men like oil. if you look through these trees right i through these trees right there, you can see it building up. it is on the other side of that ridge, so it is coming up on top of the ridge. what will happen as it will actually start backing down and that is where we are doing our structure protection right now. doyle's team are trying to cut down trees near the property to form a project of barrier from the oncoming blaze. a few hundred metres away and the

fire is laying siege to this home. this is punishing work. it is over 30 degrees here in the sun but close to fires like this and the heat can feel unbearable. it's also dangerous work. as fire ravaged trees disintegrate. this is how firefighters are trying to put out the fire. it creates these long lines with bulldozers to get rid of the trees, creates a fire line and the hope is, contain the fire. it is semi— contained here but the vast majority of this fire isn't and it is incredibly hot. beth can see the billowing smoke from her front porch. the see the billowing smoke from herfront porch. the house is under pre— evacuation which means of the fire start spreading in the wrong direction, she will have to leave and quickly. i direction, she will have to leave and quickly.- leave and quickly. i found myself. _ leave and quickly. i found myself. i _ leave and quickly. i found myself, i don't _ leave and quickly. i found myself, i don't know- leave and quickly. i found myself, i don't know if. leave and quickly. i found i myself, i don't know if these other stages of grief but alternating between extreme sadness, fear, anger too. i think that's what i'm settling on a little bit in that this is the new reality. this is

news thank you so much for joining us and from me and the team, do stay with bbc news for the latest in the global headlines and analysis and i will see you again tomorrow on tuesday. —— newsday. hello there. it felt rather cool for the time of year on tuesday across much of the country, particularly in the north and the west, where we also had 1—2 heavy showers around. but high pressure dominates the scene, as well, as we head into wednesday, but its centre will be pushing towards the east of the country — and that means gradually, we'll start to import air from the south. always a slightly warmer direction, so it'll feel a touch warmer i think across the country on wednesday. we start off dry and sunny, but through the afternoon, cloud will tend to build, many places will turn quite grey, and we could see a few showers sparking off, particularly northern england in towards scotland. temperatures a bit higher — 19—20 celsius in the north,

and around 20—23 celsius across england and wales, and winds will remain light. now through wednesday night, we continue with this slightly warmer southerly airflow. quite a bit of cloud around, some splashes of rain here and there, particularly through central areas. and temperatures no lower than around 13—15 celsius in the south, still a few cooler spots in the north. so, it is warming up as we end the week. for all areas, but in particularfor england and wales, it won't be wall—to—wall sunshine, there will be quite a bit of cloud around, and also some showers again, affecting more northern and western areas. thursday, our area of high pressure is very weak, out towards the north sea, bringing south southeasterly winds — these weather fronts slowly encroaching into the far west of the country later in the day. so, it'll going to be a pretty benign day, light winds, variable clouds, some sunshine around — the best of the sunshine across central and southern areas, thicker cloud across northern england and scotland, where we could see some splashes of rain here or there. but it'll feel warmer, up to 21 celsius in the central belt of scotland, maybe 24—25

celsius across the southeast. similar story on friday — probably a chance of seeing some showery rain through central and northern parts. best of the sunshine in the south with the highest temperatures. but we'll start to see these weather fronts encroaching into the west of scotland, northern ireland later in the day. again, a warm day — up to 22 celsius in scotland, perhaps up to 27—28 in the southeast. beyond friday into the weekend, it looks like low pressure could bring more substantial rain to the north and the west of the country. very little rainfall getting into the southeast, where we really do need it. so, it'll stay quite warm into the weekend, though, with low pressure nearby, certainly to the north, we're likely see the rain here, and there will be quite a bit of cloud around at times, too.
