tennis star novak djokovic is facing fresh controversy after photos and footage have emerged of him in public, without a mask, at around the time his lawyers say he tested positive for covid—19. australia has banned him from entering the country to defend his australian open title because he has refused vaccination. his lawyers say he doesn't need one as his infection was confirmed by pcr test on 16 december and he has since recovered. djokovic posted these images to his twitter page on 17 december. he's pictured at an event the day before commemorating his own personal stamp. it's unclear whether djokovic knew he had covid when these photos were taken. he's currently in an immigration detention centre ahead of an appeal hearing on monday. the bbc�*s shaimaa khalil reports from melbourne. the world's top tennis player is spending the weekend in an immigration detention hotel. and his supporters have turned up for a third day. this is novak djokovic arriving in melbourne on wednesday. the documents his legal team presented to the court state he'd received the exemption from tennis australia, with a follow—up letter from the home affairs department, saying he was allowed into the country. his legal team added that on 1january, djokovic received a document from home affairs, telling him his responses indicated he met the requirements for a quarantine—free arrival into australia. what's becoming clear is a breakdown in communication among those making the decisions, and what the judge has to look at and examine is exactly which rules apply. is it state government rules or federal government rules? and until a decision is made about whether novak djokovic can remain in australia, the world no—one is still stuck in this immigration detention hotel, and in the middle of a huge controversy. this particular set of incidents, the victorian government's not briefed on the matter. in terms of how people got into the country, that's a matter for the federal government. last night his mother offered some reassurance. he said he's ok, but i'm not so sure. but he's mentally very stable, and he's waiting. the tennis tournament is only a few days away, and what's normally one of the biggest highlights here is turning into a political and a diplomatic embarrassment for australia. shaimaa khalil, bbc news. i've been speaking to mary crock, a law professor at the university of sydney. she says djokovic�*s lawyers have created a strong case. i have now been able to read the submissions put in on behalf of novak, and i think it's going to be a very interesting case. he's got good lawyers and they seem to have made very interesting legal arguments that could well play out in his favour. so you think there's a chance he could make it to the australian open, but there are quite a few complications about this case, aren't there, there seem to be lots of different sides, the state side, the federal side, and also the border force. look, the case that's been put to court is really based on very close reading of the actual migration law and i agree with you, i think the policies that apply, both at a state level and at a federal level are far from clear, you've got bio security legislation, you've got the migration act, you've got policies made under the migration act and then policies that seem to be changing almost by the day coming out of an organisation called atagi, and so there will be very interesting questions about the status of all the different policies and, indeed, the ground that was relied upon by the decision maker to cancel the visa in the first place. and i think, for me, one of the interesting questions is, first, of course, what does the judge decide in terms of the legality of the cancellation? but the judge can either say i'm going to vacate this decision altogether and pretend it didn't happen, in which case novak gets his visa back straight away, apparently, or he can refer the matter back for reconsideration, in which case the saga drags out. so everything's unclear at this point and everything is very, very interesting. yeah, it almost doesn't matter about his vaccination status anymore, does it, it's more of a legal wrangling. i wanted to bring up the fact that, for a wider case, it brings up this issue, doesn't it, of strict border laws, strict border restrictions that we've had in australia over the last two years, families have been kept apart, but also for migrants and people trying to get into the country, this has really shone a light on just how strict australia are. well, absolutely. i think the problem with his case is just how unclear the laws are at this point, because some people are being allowed in — they knew about novak�*s status before he left serbia and the big question on everybody�*s lips is why wasn't this sorted out before he got on the plane, what is with the drama of keeping him up all night to then take him into the same hotel quarantine detention centre where the refugees are being kept? mary crock there. speaking to me earlier. more than 150,000 people in the uk have now died, within 28 days of a positive covid test. another 313 deaths have been reported in the latest daily figures. the uk is the seventh country to pass this number of official deaths after the us, brazil, india, russia, mexico, and peru. it comes as britain experiences its worst wave of coronovirus cases yet, as the highly—transmissible 0micron variant sweeps across much of the country. 0ur health correspondent catherine burns takes a look now at the toll the pandemic has taken on people around the uk. how do you begin to imagine 150,000 people? it's almost the entire population of oxford, a city, like others, where the pandemic has caused so much pain. the first death within 28 days of a positive covid test was recorded in the uk on 6 march, 2020. five weeks later, more than 10,000 people had died. sabir—hussain mirza was 0xford's first muslim councillor. mostly, though, he was a family man — married with ten children. they relied on video calls when he went to hospital. we would be like, "come on, dad, get better quickly and come back." but one day sabir stopped answering his phone. he'd been put on a ventilator. after almost three weeks, doctors said some of the family could visit him for the last time. i said to him, "i love you, and i want you to know that i will always love you, and i will never forget you." you just can't come to terms with someone actually telling you that your father's left this world. sabir was buried next to his younger brother. he'd died the day before in the same hospital, killed by the same disease. as the pandemic spread through society, the death toll rose rapidly, but scientists in this city were also working at speed, racing to find a vaccine, and by the end of april 2020, the oxford astrazeneca team was already testing it on volunteers in clinical trials, and as the year came to a close there was a real sense of optimism as both this and the pfizer vaccine were approved. january last year was a turning point — it saw more deaths than at any other time, over32,000. but by the end of the month almost half a million people had had theirfirst dose of a vaccine. she was looking forward to the vaccine coming along. traceyjones turned 50 in lockdown. she didn't make it to 51. she said to me, "i feel very, very ill." isaid, "i know, my darling, they're going to put you to sleep and you'll be better." she said to me, "look after stephen," and those were the last words i ever heard from her. neil and tracey were a team, caring for their son stephen who has special needs. i had to tell him, unfortunately, "mum has gone to heaven now," and he hugged me and cried. no—one could come and see you. we were left to grieve on our own, really. it's very hard, especially when you have a special needs son, and you don't want him to see you crying, but sometimes you just had to go away and have a little cry. the pandemic has seen too many sad milestones. in november, 2020, the death toll stood at 50,000. just 11 weeks later, it reached 100,000. vaccines helped slow that pace right down. it's taken almost another year to get to this point. i'm so glad that he retired when he did, early. robin birchmore was 63. his invitation for a vaccine came through two days after he died. in hospital, he had one last video call with his daughter. he kept saying, "i'm struggling, i'm struggling to breathe," and i said to him, "hurry up and get better," and he said, "i'm trying." that was the last time i spoke to him. camilla's nan had also died from covid. 0n the night after her funeral the call came, it was time to say goodbye to her dad, too. it was horrendous, horrendous. the doctor said, "here's your dad," and i went, "that's not my dad." i didn't even recognise him because of all the tubes. you say your goodbyes and then you have to walk away from them. the uk has reported 150,000 deaths before any country in the eu. there is hope, though, that this pandemic will never again bring suffering on such a scale. catherine burns, bbc news. now let's turn to the us, where coronavirus cases continue to surge to record levels. by the end of the month, according to the centers for disease control and prevention, covid will be sending between 20,000 and up to 50,000 americans to the hospital every single day. america's health—care system is becoming increasingly under strain with many us hospitals depleted by an exodus of healthcare workers. of those who have stayed, many now can't work, because they have 0micron breakthrough infections. furthermore, us economy experts are warning almost five million americans could call in sick in the coming week in a major disruption to the economy and essential services. we can now speak tojeremy faust, who's an emergency physician at brigham and women's hospital and an instructor at harvard medical school. thanks forjoining us. how worried are you, half a million cases every single day doesn't sound too good.— sound too good. think you for havin: sound too good. think you for having me- — sound too good. think you for having me. no, _ sound too good. think you for having me. no, that - sound too good. think you for having me. no, that doesn't l having me. no, that doesn't sound good at all. and we know that 0micron might be a little bit milder, but if you look in the hospitals we see patients have coronavirus looks just like it did in 2020. so if you combine that with the amount of care we have for other things, influenza, heart disease, things though, quite frankly, we had a lot lower levels of a year ago, and you have this combination that is putting the hospitals all around this country on the brink of overflowing. so, yeah, we are vaccinated throughout the older population, we have some immunity from prior infection, but all that is raised by the fact that we are taking care of so many other patients and the extravagant contagion of this variant means it finds everybody. so right now providing the top care that we are able to do becomes more and more difficult with each day. absolutely. can you draw any parallels to europe to see where this is going, because obviously it hit europe first, the 0micron wave, is there anything you can do to look across the pond and so we can look out for this all, you know... it look out for this all, you know - -_ look out for this all, you know... , , , . know... it is very difficult. in south — know... it is very difficult. in south africa, _ know... it is very difficult. in south africa, for - know... it is very difficult. i in south africa, for example, it is a different time of year, so there is analysis i think will begin to understand. when you look at the uk and the eu compared to the united states there is a very big difference in terms of the leg of mitigation in every community, the density of the populations, the density of the populations, the age of the vaccinated. we have a lot of people in this country who are vaccinated or older, but we also have below are not vested in that age group. young people can get this virus and spread it. so i think that is what is happening. we are seeing that several weeks ago younger people were the people getting it. you saw the long lines of people waiting for test, those were young, healthy people. unfortunately, the holidays they bring the back to relatives who maybe don't take as many risks on a usual basis are now those people are starting to show up at hospitals with a nursing home outbreaks for the first time in a while, and that really gives us concern, because when we see nursing home outbreaks we know that hospitalisations are close to follow. it that hospitalisations are close to follow. ., , ., , , that hospitalisations are close to follow. ., , , to follow. it obviously has knock-on _ to follow. it obviously has knock-on effects - to follow. it obviously has knock-on effects to - to follow. it obviously hasj knock-on effects to public knock—on effects to public life, when people start to stop going to work, tens of

transport? all these disruptions are just | transport? all these - disruptions are just adding insult to injury. 0ne disruptions are just adding insult to injury. one thing that i think is interesting is that i think is interesting is that we're never to control this virus in terms of getting to know infections but i wanting to advocate that we don't get ablaze with hospitals are full. so slowing down the virus were the hospitals are on the brink makes a difference. when there is a snowy day, that keeps people home, that can actually cut transmission a little bit. so anything helps. but, unfortunately, people staying home is not what they want to do. but what i will say is when that happens it is a little bit there is one bright side of that, it increases the —— decreases the number of large situations with supersprint happens. increasingly i think that is how this virus spreads, it takes advantage of a few individuals who are extravagantly contagious, gives it to people in the room, that is how these things move. so i think when we say i'm a little bit, we're tired it, but very few days and keep the hospital stay. few days and keep the hospital sta . , . , , , ., stay.

headlines this hour: more controversy for novak djokovic as footage emerges of him in public at the time his lawyers say he tested positive for coronavirus. more than 150,000 people in the uk have now died within 28 days of a positive covid test since the pandemic began. it's the first country in western europe to reach the figure. in pakistan, the bodies of people who died after becoming trapped in their cars by heavy snow, have begun arriving in the capital islamabad. —— trapped in their cars by heavy snow have begun arriving in the capital islamabad. at least 21 people perished after hundreds of vehicles became stranded by unusually heavy snowfall around the hilltop town of murree, to the north—east of the capital. gareth barlow reports. the tragic outcome of what was supposed to be an enjoyable weekend. at least 21 people died after their cars became engulfed by heavy snow. included in the victims, a policeman, his wife and their six children. military units and other emergency services were deployed to clear roads and handout supplies to stranded motorists as they waited to be rescued. the chief minister of punjab has tweeted that those left stranded by the record snowfall have now been moved to safety. and while work to clear snow continues, many of the area's routes have been reopened — although roads leading to murree remain sealed off by the authorities. as ambulances transporting the bodies of people who perished arrived in islamabad, the row over who's to blame for the disaster has already begun. taking to twitter, opposition politicians pointed to the fact the extreme snowfall had been predicted, with claims government officials had not taken steps to prevent the huge influx of tourists keen to enjoy the winter weather. the pakistani prime minister imran khan has ordered an enquiry into the disaster. before that's completed, further heavy snow is expected to fall. gareth barlow, bbc news. the newjames webb space telescope has fully deployed in space — the final step of its two—week deployment phase that began with its launch on christmas day. nasa will now begin to latch the wing into place. the observatory is on a mission to study the very first stars to shine in the universe. many of its components had to be folded to fit inside the launch rocket. 0nce unfurled, the golden primary mirror, the largest astronomical reflector ever sent into space, will allow the telescope to be properly focused. its great size will enable scientists to see the faintest objects from the farthest reaches of the cosmos. let's speak to katherine mack, a theoretical cosmologist and assistant professor at north carolina state university. nq n0 forjoining us. just how big a moment was this for you because the launch on christmas day was one thing but this really was the moment of truth, wasn't it? —— thank you. really was the moment of truth, wasn't it? -- thank you.- wasn't it? -- thank you. yeah, this whole _ wasn't it? -- thank you. yeah, this whole mission _ wasn't it? -- thank you. yeah, this whole mission has - wasn't it? -- thank you. yeah, this whole mission has had - wasn't it? -- thank you. yeah, this whole mission has had a i this whole mission has had a soul on the edge of our seats. it's such a complicated mission in terms of, just has so many parts. as you mentioned, this telescope had to be folded up to fit into the rocket and so that means that once it was launched, all of these parts had to be unfurled and it all had to be unfurled and it all had to be unfurled and it all had to go perfectly right in orderfor this had to go perfectly right in order for this telescope, which has been 20 years in development, to be functional. and it's such an expensive mission and such an important mission, of alljust been really, really hoping it went well and so far, it is going amazingly well.— well and so far, it is going amazingly well. yeah, well, i wanted to — amazingly well. yeah, well, i wanted to talk _ amazingly well. yeah, well, i wanted to talk about - amazingly well. yeah, well, i wanted to talk about that - wanted to talk about that because $10 billion, 30 years in the making. are you surprised by how smooth it has gone because even nasa said they were not expecting it to go so well. they were expecting some pick—ups. go so well. they were expecting some pick-uns— go so well. they were expecting some pick-ups. well, you know, i have just _ some pick-ups. well, you know, i have just been _ some pick-ups. well, you know, i havejust been hoping, - some pick-ups. well, you know, i havejust been hoping, i've - i havejust been hoping, i've been trying to get not to caught up at —— caught up in it and not get too emotionally involved because this is involved because this is involved in the kind of science i do, i'm interested in cosmology and the study of the history of the universe and this will show us some of the first structures ever formed in the cosmos and we have been waiting so long for these intervenes been so hopefulfor it, iwill intervenes been so hopefulfor it, i will say i am surprised because i know how much work went into it and how careful the engineers have been and how much testing they have been doing but i'm very relieved. and it's not the end of the road yet, is it, until it is absolutely up and running. what needs to happen _ absolutely up and running. what needs to happen now? - absolutely up and running. what needs to happen now? now- absolutely up and running. what needs to happen now? now that the mirror _ needs to happen now? now that the mirror is _ needs to happen now? now that the mirror is fully _ needs to happen now? now that the mirror is fully deployed, - the mirror is fully deployed, all of those segments are in place, they need to tune it, basically. i need to make sure all of those mirrors are aligned. there are 18 mirror segments and all of them have to be aligned together in order to be aligned together in order to form an image i'm sorry, that's the next step. a minute will do another burn put it into the right orbit and then there will be a few months of just calibration, making sure that all the instruments are working and making sure the images look the way they should, so there's still a long road but all of the really big, scary parts happened now. find scary parts happened now. and we can tell _ scary parts happened now. and we can telljust _ scary parts happened now. and we can telljust how _ scary parts happened now. and we can telljust how excited you are by this, you are grinning earto ear. you are by this,

telescope has some when we look into the distance in the cosmos, we're looking into the past because of the way that light takes to travel to us of this instrument is going to look back 13.5 billion years into the past. now, the universe is only 13.8 billion years old is about going to be able to see some of the things that are performed in the cosmos, some of the first galaxies, and it will also be looking at the atmospheres of planets around other stars to determine maybe they can have life on them. it's going to look at where stars are born and nebulae, there will be so much amazing science from this mission and it was going to tell is just so much more about the history and the creation of the universe. really exciting and some positive news, if ever there was needed. katherine mack, thank you so much for bringing us that. ., ., thank you so much for bringing us that. ., ~ , ., now for a doggy tale of international travel with a difference. munchkin was a bali street dog until natasha corbin and herfiance david daynes came across the puppy while they were living in indonesia. and since then, munchkin has been on quite a voyage because natasha has spent the last six years working to have her reunited with them back home in australia. and having passed throuthakarta, singapore and new zealand, munchkin finally made it to queensland just before christmas. earlier, i was able to talk to natasha, david and munchkin, and i began by asking natasha how they'd first come across the dog in bali. we were living in bali and at the time, i was not supposed to talk to or look at any dogs because i'm such a dog lover and david knew that i would just fall in love with a dog and want to keep one. and this little doggo kept following us home and we just fell in love with her and our neighbours actually asked us to take her in while they found a new home for her and unfortunately, itjust didn't work out and so, we decided after a year of trying to rehome her that we would keep her and try and bring her back to australia. and you've obviously have brought her back to australia and she's doing a greatjob at the moment, and well done for keeping her sedate, guys. but i think — can you talk us through the hurdles and all the steps that you had over the last six or seven years to get her home? yeah, so it was supposed to take around six weeks and $10,000 to get her from bali all the way through to australia but she got stopped a couple of times on the way, just complications happened, so in singapore, her rabies vaccine wasn't strong enough, so she had to stay there for six months and then while she was there, she got a tick virus which meant she could not come to australia. and then we found out a couple of years ago we could take her to new zealand and live with her there, because we were not able to live with her in singapore, so we were visiting singapore to visit our dog regularly. and so then, when we found out we could take her in new zealand, we did that. and then, when she finally got cleared to travel to australia a couple of months ago, because of covid, all of the flights were being cancelled and so, i was in australia for a surgery, david was with munchkin over in new zealand and we were worried that we weren't even going to be able to be together for christmas, so we were frantically searching for ways that we could get them home with all the flights being cancelled. we looked at private jets, we were looking at charters and all sorts of things but we were very fortunate that we had someone reach out to us who had seen our story and they were organising their own private charter and we were able to jump and get david on those. i mean, it sounds like — it sounds like homeward bound — that was my favourite film growing up — itjust sounds like an incredible story that you will, no doubt, sell to hollywood for millions soon. can you just tell us about — because we've got pictures of when you were finally reunited with munchkin — just tell us about that moment. yeah, it was pretty special. i had been separated from them for over six months, having surgery here in australia. and so, i wasjust so, so missing them and so excited to see them. and when she finally came off the plane and she came down on the little forklift and she looked so scared but it was such a magical moment and she did not shut up for, like, 20 minutes after we finally were reunited. she was just squealing with excitement and every now and then, she would stick her head up and squeal at me again. it was so beautiful. natasha speaking to me earlier about munchkin and getting her back seven years after she last saw her. that's about it from us for now. you can reach me on twitter. i'm @sipusey. thank you for watching. stay tuned right here to bbc news. hello again. it was quite a wet and windy start to the weekend. saturday brought widespread outbreaks of rain. the wettest place, north west wales, capel curig picking up 34mm of rain. the strong winds towards the isle of wight pushing the waves into the coastline here. towards the end of the day, we had a lovely sunset in dumfries and galloway in west scotland. now, the driving area of low pressure that brought the wet and windy weather on saturday is here and it's still on the charts through sunday. what's going to happen is it's going to weaken significantly as it moves its way across scotland. however, it will still be bringing a little bit of rain with it across parts of scotland and northern england as well. now, for the time being, we've still got some fairly brisk winds blowing in. they're bringing scattered showers across western areas. there's a little bit of sleet mixed in with some of these across the higher ground, scotland, northern england, northern ireland as well, with temperatures close to freezing but on the whole, just staying above — except in northern scotland, where temperatures could get down to about —5 in the deeper valleys in aberdeenshire. now, for many, it's going to be a fine start to the day but that area of low pressure is going to push this band of rain across scotland, northern ireland and through the afternoon, the rain moves its way across northern england. it will turn lighter and patchier, perhaps reaching the north of wales late in the day. still across the midlands, east anglia, most of southern england a lot of dry weather but we end the day with this band of light, patchy rain pushing into cornwall. well, that is associated with this warm front and that warm front is going to pivot its way in to the uk as we go through monday. now, with that, yes, will come mild air, but there will be a lot of cloud around, mist and fog patches quite common around the coasts and hills, and it will be quite damp at times, too, with a bit of light rain and drizzle. a bit of heavier rain into western scotland, where a cold front will begin to move in late in the day. temperatures then are the mildest across western areas of the uk just ahead of this front. in the east, a little bit cooler — highs of around 7 or so. now, by tuesday, this is our cold front now pushing its way southwards across england and wales. that will clear outbreaks of rain southwards. a mixture of bright spells and showers for scotland. a lot of dry weather in between for northern ireland, northern england and north wales as well but you'll notice the cooler air starting to move back in from the north and west with temperatures here around 7 or 8, the mildest air in the south. now, beyond that, high pressure is going to build into the south of the uk and that means increasingly, in the week ahead, the weather will become fine and dry with some sunny spells. this is bbc news. the headlines: tennis star novak djokovic faces more controversy afterfootage emerged of him in public around the time his lawyers say he tested positive for covid19. they're claiming the infection exempts him from australia's vaccine rules, where he's currently detained in an immigration hotel after being barred from entering the country. more than 150,000 people in the uk have now died within 28 days of a testing positive for coronavirus. it's the first country in western europe to reach the figure. at least 21 people have died in freezing temperatures in northeastern pakistan after their cars were trapped in heavy snow. the chief minister of punjab province, has declared the mountain resort town of murree, where a thousand vehicles were stranded, as a "disaster area," warning people to stay away.
