tsunami warnings across a vast area, including japan and the entire us west coast. hello and welcome if you're watching in the uk or around the world. in the next few hours, novak djokovic will hear whether or not he'll be allowed to remain in australia. the government says the world number one tennis player, who hasn't been vaccinated against covid, is a threat to public health. his lawyers are appealing, describing the latest decision to cancel his visa, as irrational. shaimaa khalil reports from melbourne. free the refugee! once again, novak djokovic is in detention, and once again, the world number one is challenging the cancellation of his visa. in court documents which were released today, we learned that the immigration minister alex hawke made his decision because the player's presence in australia may foster anti—vaccination sentiment. the tennis star's legal team says the argument was invalid and irrational, and that deporting him would potentially undermine support for the vaccination programme. we want novak djokovic to play! and while some of djokovic�*s supporters gathered to back him, there has been little sympathy for the tennis player. i do feel that to make a statement that we are sticking by what we have been calling for the last two years, i feel it is best for djokovic to probably sit this one out. i hope that the government and the judges hold their ground and say, you don't want to get a vaccination and you don't want to follow our rules, then you can't come in. when novak djokovic�*s visa was revoked the first time, he was held here at this immigration detention hotel. more than a week later, he's back. only two days before he is meant to compete in the australian open and defend his title, this is where he will be spending the night. and when he does get out on sunday, it won't be to go to practice — he will be in his lawyer's office while a court decides his fate. his rival rafael nadal said the grand slam is not just about djokovic. the australian open is much more important than any player so if he is playing, finally, ok, if he's not playing, the australian open will be a great tournament with or without him. that is my point of view. sunday's court decision is crucial for both sides — the top seed whose chance at a 21st grand slam rides on it, and a government that has been hugely embarrassed by the mishandling of the saga. shaimaa khalil, bbc news, melbourne. some breaking news for you now. police in the us state of texas are negotiating with a man who appears to have taken hostages at a synagogue in the town of colleyville. these are live pictures outside the synagogue. it's not known if the hostage taker is armed or if anyone has been hurt. it's also unclear how many people were attending the service, which was being streamed live when the incident started. the feed has since been taken down, but not before an angry man could be heard saying he didn't want anyone to be hurt. police have deployed swat teams to the scene and are asking people living in the area to leave their homes. just to bring you up—to—date with their breaking news, police in texas are negotiating with a man who appears to have taken hostages in a synagogue. lawyers for the duke of york want to question two people as part of the civil sexual abuse case being brought by virginia giuffre in america. according to court documents, prince andrew's legal team argue ms giuffre may be suffering from false memories, and they want to hear from her husband and her psychologist. prince andrew denies all the allegations against him. our correspondent in washington, nomia iqbal has more. this comes 2a hours after virginia giuffre requested witness accounts from prince andrew's former assistant and a woman at a nightclub at the time of the allegations, and now the prince has hit back with requests of his own. as you mentioned, his legal team wants to hearfrom her husband, robert giuffre. they want to know how he met his wife in 2002, the household finances. they also want to ask about virginia giuffre�*s relationship with the convicted sex offenders jeffrey epstein and ghislaine maxwell. the duke's side is claiming that mr giuffre had a role in recruiting underage girls to be trafficked. they also contend, as you mentioned there, that she may suffer from false memories, which is why they want to examine the second person, her doctor, a psychologist, judith lightfoot. now both the husband and doctor are residents of australia, so the duke's legal team have requested that letters are issued from the us court to the central authority of australia to get the testimonies. the senior uk conservative mp and former minister tobias ellwood says borisjohnson must lead or step aside, following the controversy over gatherings at downing street while covid restrictions were in place. a number of tory backbenchers say they've been inundated with messages from angry constituents, about the growing list of parties, dating back to the spring of 2020. the opposition labour leader, sir keir starmer, says it's now in the national interest for mrjohnson to be removed from office. our political correspondent iain watson has the very latest. borisjohnson has come under renewed pressure following number 10's apology to buckingham palace over a leaving do held last year on the eve of the duke of edinburgh's funeral. so today the labour leader urged conservative mps to force him out. of course there's a party advantage in him going, but actually it's now in the national interest that he goes, so it's very important that the tory party does what it needs to do and gets rid of him. usually when opposition mps call for a prime minister to go, the troops rally round, but today the conservative chairman of the commons defence committee, tobias ellwood, did not exactly defend his boss when he told the bbc borisjohnson should lead, or step aside. outside downing street, demonstrators against a forthcoming police bill were making their views of the prime minister known. far more subtly, some of his own mps have also been doing so. what may be worrying the prime minister is that some of his former supporters now want him to go. one mp, elected in 2019, told me he owed his seat to borisjohnson but now, he says, this feels terminal, and he should go quickly. and another mp i spoke to several days ago, who told me then that he thought borisjohnson could ride out this political storm, got back in touch today to say he's now damaging the conservative brand and it was a question of when, not if, he leaves number 10. no cabinet minister, though, has broken ranks and there is hope inside downing street that an investigation by a senior civil servant may say that the prime minister has not broken covid rules. and the expected lifting of restrictions later this month could improve his mps�* mood. this weekend, conservative mps will be listening closely to their voters and the mood on the doorstep could determine whether the prime minister is shown the door. iain watson, bbc news. the us and japan have advised people on their pacific coastlines to get away from the shore after an underwater volcano erupted close to the island of tonga, for the second time in two days. satellite images captured the moment, as huge plumes of black ash darkened the sky. the huge eruption caused waves of more than a metre to crash into tonga. many parts of the island are covered in ash and experiencing a near—total blackout of power and communications. earlier, i spoke to dr kayla iacovino, a volcanologist who told me more about the eruption. what really makes this eruption significant is its size coupled with the fact that and we've been able to witness it first hand with the satellite images. early reports are coming out now from the tonga geological service. we still do not know how much material erupted, which will help us to classify the size, but we know the volcanic plume was about five kilometres wide and as much as 20 kilometres high, which is really significant, particularly because that indicates that this eruption rose into the earth's stratosphere, which is the zone of our atmosphere which allows volcanic material to spread out around the globe, creating further reaching impacts. i guess that explains then the scale of it because we've seen the tsunami waves on tonga, the island closest to this volcano, but we've also had tsunami alerts and waves across the us west coast, australia, new zealand, as far away asjapan, so what does this say about the sheer strength of this eruption? well, the eruption was very short but it was very explosive. so it tells us that there was enough energy released in this very short—lived blast that was able to explode water, push water out of the way and create this shockwave that sent ripples are literally across the globe. it goes to show you how far—reaching volcanic impacts can be when there are people in washington state and japan worrying about something that literally happened on the other side of the globe. most destructive tsunamis generated by earthquakes, what do we make of this, that it is an underwater volcano creating these powerful waves? that is certainly one of the things that has probably contributed largely to how explosive the eruption was. when some magma rising from beneath the surface comes into contact with surface water or ground water, it heats that water so quickly that it turns to steam and then a huge chain in the volume of water that it goes from liquid water to steam and that is essentially one of the main driving forces. in addition to that rising magma and exploding lava, that is another force that causes this massive explosion. and it really creates this effect that can be felt so far away. this is an area of seismic activity, so are we expecting to see more of this? this is of course the second any number of days. it is impossible to say if it will erupt again on this scale. certainly probably the volcano will erupt again, but we really don't have a good way currently to predict eruptions, certainly not more than hours or days ahead of time. this volcano looked like it was actually waning in activity until this really explosive event happened. i know the local authorities there, the tonga geological service are keeping a very close eye on it. the rest of us around the world will be looking to them over the next few days to see if we see more precursors such as earthquakes near or underneath the volcano which could indicate that another eruption might occur. large crowds of hindu worshippers have gathered on the banks of india's ganges river for a holy bath in spite of a 30—fold increase in coronavirus cases in the past one month. similar festivals are taking place across the country. doctors in west bengal applied to stop its festival this year, worrying it would become a super spreader event. india reported over 260,000 new coronavirus cases on friday. aru na iyengar reports. varanasi in the northern state of uttar pradesh. thousands of pilgrims throng the ganges river banks to take part in the magh mela festival. they believe bathing in these sacred waters will wash away their sins. translation: nobody - is following the guidelines. announcements are being made to urge people to wear masks. what can the government do? the mistake is on our part that we should be following the rules, but nobody is following the rules, nobody is ready to listen to the rules. at the gangasagar festival in west bengal, officials try to enforce covid restrictions. pilgrims have to show their vaccine certificates along with an rt—pcr test report ta ken two days before arrival. but most here believe god will save them from covid. three million people are expected here. doctors asked the state high court to stop the festival, fearing it would become a super spreader event, but that was rejected. they are worried because last april there was a record rise in coronavirus cases after the government of uttarakhand state in the north allowed the massive kumbh mela festival to go ahead. the indian prime minister, narendra modi, says the festivals show india's vibrant cultural diversity. meanwhile, coronavirus cases are predicted to peak next week in new delhi and mumbai as the country battles with the highest number of cases since may last year. aruna iyengar, bbc news. thieves are leaving thousands of opened and damaged packages strewn across the railway tracks in east los angeles after

hasn't been delivered, you might want to check the rail line in the east of the city. freight trains passing through this area have become an easy target for thieves, who leave evidence of their raids all over the tracks. as trains head into a busyjunction, they often slow down or stop, and looters are ready. theyjump on these trains. these locks that these containers have are really sometimes plastic seals, the locks aren't really sturdy or strong, you know. they don't care if the train is moving or not. theyjump on the train, pop the lock and just start grabbing whatever they see. all of this has accumulated over the last month alone. looters aim for the most valuable items they can find, ripping through packages and avoiding cheaper bulk cargo items like toilet roll. towards the end of last year, more than 90 containers were vandalised every day. thefts peaked around christmas. according to the rail operator union pacific, over the last year looting along the train line in los angeles county has risen by i60%, costing millions of dollars. the thefts have hit major companies, including amazon, ups and fedex. the rail operator says it has now increased security along the

to tighten manchester city's grip on the premier league title with a 1—0 victory over second placed chelsea. the former chelsea player broke the deadlock, in what was a tight game, with 20 minutes left, to extend city's lead at the top of the table to an imposing 13 points. chelsea had their chances though, the best coming when ederson saved from romelu lukaku in the second half but it was de bruyne who made the difference. we had ten chances against the team, european champions so we realised how incredible they are, how aggressive they are, and it is football so they wait in the transition to punish us and we scored a goal in the transition so but well deserved, they complement for the team because we know exactly when his team played how good they are. it was certainly a debut to remember for philippe coutinho — who helped aston villa come from 2—0 down to draw 2—2 with manchester united. defensive errors by the villa goalkeeper emiliano martinez and midfielder morgan sanson helped bruno fernandes score twice to give united a 2—0 lead. villa boss steven gerrard sent on his former liverpool team mate immediately after united's second and the brazilian did no disappoint, setting upjacob ramsey and then scoring the equaliser. the result moves villa up a place to 13th. united are in 7th. at the other end of the table, newcastle drew 1—1 with watford. joao pedro's equaliser keeping the visitors clear of the bottom three. the club that had been bottom of the table, norwich ended a six—game losing run with a 2—1 win over everton. norwich move up to 18th, adding to the pressure on the everton boss, rafa benitez. adama traore scored his first goal of the season in injury time to give wolves�* their third win in four premier league games. robert lewandowski scored his 300th bundesliga goal on saturday by scoring a hat—trick in bayern munich�*s 4—0 thrashing of koln, the reigning champions restoring their six point lead at the top of the table. also on saturday, union berlin were 2—1 winners over hoffenhaim. and there were victories for rb leipzig, mainz and bayer leverkusen. to italy next where torino beat sampdoria 2—i. dennis praet with the winner for the visitors. lazio beat salernitana 3—0. and in the late gamejuventus are leading udinese 1—0 with around 20 minutes remaining. at the africa cup of nations, nigeria made it two wins out of two as they sealed their place in the knockout stages by beating sudan 3—1. thanks to goals from samuel chukwueze, taiwo awoniyi and moses simon. walieldin khedr pulled a goal back for sudan from the penalty spot. and in the day's other game mo salah's 69th minute strike gave egypt their first win of this africa cup of nations — a crucial three points from their victory over guinea bissau. a court hearing to decide whether novak djokovic can stay in australia — or not — is set to start in a little over an hour's time. the world number one is scheduled to begin the defence of his title at the australian open on monday. but he has been back in a detention hotel in melbourne pending the case. djokovic, who isn't vaccinated against covid 19, faces deportation after his visa was cancelled for a second time. his legal team have been preparing his case following the decision by australia's immigration minister to cancel djokovic's visa on the grounds of "health and good order". staying with cricket and virat kohli has stepped down as india's test captain with immediate effect following their disappointing series defeat in south africa. in a statement on social media kohli said: "it has been 7 years of hard work, toil and relentless perseverance everyday to take the team in the right direction. every thing has to come to a halt at some stage and for me as test captain of india, it's now." that's all the sport for now. the bbc website has more including the cricket. a year of events to celebrate france's most famous playwright moliere are getting underway. it's the 400th anniversary of moliere's baptism, his birth date isn't known. celebrations are starting with a rendition of tartuffe, a satire on the catholic church. the play was censored after its first performance in 1664. although he is considered the father of french theatre, his influence has been felt across the world. including here in the uk. aneel gupta, the bafta—winning writer and executive producer behind the office and also citizen khan and the kumars at number a2. aneel, you adapted the story of ta rtuffe into a play about a british—pakistani family in modern—day birmingham. how does that work? amazingly, it works quite well. the rsc had the idea, i think because obviously as you mentioned, the original play was an incredibly dangerous piece of work and you could have got killed for doing that sort of thing in 17th—century france where it was, as with a lot of great comedy, walking on a very thin tightrope, in terms of taste and what the public were prepared to accept. so, i think the feeling was that perhaps over the 400 years, it had lost some of its edge and by reframing it in this context of a pakistani muslim family in modern day birmingham, you suddenly, there is a elective intake of breath among that collective —— among the audience and i think that is what it needs. it is among the audience and i think that is what it needs.— is what it needs. it is fascinating to hear you _ is what it needs. it is fascinating to hear you talk _ is what it needs. it is fascinating to hear you talk about _ is what it needs. it is fascinating to hear you talk about it - is what it needs. it is fascinating | to hear you talk about it because when you think of tartuffe, many of moliere's plays were banned because they were seen as very controversial, but remind us, the story of ta rtuffe, controversial, but remind us, the story of tartuffe, this is a man who has the gift of the gab, a hypocrite, an impostor, how do you take what is a story about, a satire on the catholic church, and then put it into modern day uk life? weill. it into modern day uk life? well, because i think _ it into modern day uk life? well, because i think when _ it into modern day uk life? well, because i think when you - it into modern day uk life? well, because i think when you look i it into modern day uk life? -ii because i think when you look into the play, it is notjust so much about catholicism or religion in that sense but about the way that religion is practised, the way that it relates to everyday people and the way that it can be used by certain people. so, i think the eponymous character, tartuffe, is not really a religious character, he is a con really, he is someone who clothes himself in the guise of a pious individual and uses the power that gives him over pious religious people to his own advantage. it is actually a play about a family who are in crisis and the patriarch who is searching for some kind of spiritual meaning in his life and this character comes into his world and uses that to exploit him. you are so well _ and uses that to exploit him. you are so well known _ and uses that to exploit him. you are so well known for so many brilliant comedy that we all love, when you went to tartuffe, when you went to moliere, and you read it, did you find it funny?— did you find it funny? well, i wasn't expecting _ did you find it funny? well, i wasn't expecting it _ did you find it funny? well, i wasn't expecting it to. - did you find it funny? well, i wasn't expecting it to. i - did you find it funny? well, i wasn't expecting it to. i was| wasn't expecting it to. i was expecting, i was thinking a 400—year—old french comedy, those aren't things that go together, in my mind. so, i was very pleasantly surprised at how funny i found it, actually, and a realjoy of it and the real genius of moliere is the comic structure. you know, when you are constructing a farce, which this is, essentially, it is an incredibly intricate and very difficult and precise thing to do, and what we realised when we read the original plate was that structure is absolutely watertight. it is a gold—plated structure and we really didn't change. we were given licence to change whatever we wanted but we realise that this is a gift, we will keep all of this because it all still works, all the comic beats are there and that was the real revelation for us. an there and that was the real revelation for us. �* ., , revelation for us. an absolute gift to seak revelation for us. an absolute gift to speak to _ revelation for us. an absolute gift to speak

stories with us. and thanks for watching. now it's time for a look at the weather with stav. there was a lot more cloud around today compared to recent days but it wasn't as cold, slightly milder air moving in off the atlantic. what we will see through tonight is less cold conditions because we'll have this atlantic air mass and also a few showers around. you can see them here on these weather fronts. this one pushing into the south—west quadrant of the country and this one spreading south across scotland and northern ireland overnight. quite a few isobars in the charts so it will be turning windier here. a cluster of showers pushing into south—west england, south wales, perhaps southern england, through the night. this band of cloud and rain will move south across scotland and northern ireland, with blustery showers following behind, turning windy with gales developing across the far north of scotland. another chilly night, certainly across eastern areas where we have clear skies, but you can see generally not as cold as it has been of late. and we shouldn't have any problems with mist and fog because of more of a breeze. that weather front starts sunday lying through central parts of the country, barely anything on it as it moves south, it will be fizzling out, no more than a band of cloud by the end of the day. a breezy day for most, windy across scotland with gales certainly for the north highlands and into the northern isles. temperatures where they should be for the time of year, 7—10 degrees, and there will be plenty of sunshine around. the weather front clears away as we head into monday and this new area of high pressure builds in across the country. monday looks pretty fine, but with light winds and clear skies it is going to be chilly again, some frost and a bit of fog, but widespread dry and sunny weather. a bit more cloud and breeze for the north and west of scotland, and temperatures, after a chilly start, rising to around 7—9 degrees for most of us. subtle changes into tuesday but high pressure holds on for most, but this frontal system brushes past the north of the uk bringing more cloud, more breeze, showers or outbreaks of rain for northern ireland, scotland and northern england through the day, but some milder south—westerlies here. central and southern england and south wales, another chilly start, dry with some sunshine here. single figure values across the south, 10, 11, maybe 12 across the north. thereafter for the rest of the week, high pressure dominates the scene, even as we head into next weekend, with some sunshine and a return to overnight frost and fog. bye for now. hello this is bbc news. the headlines... the prime minister is told to "lead or step aside" as details of lockdown parties continue to
