welcome to bbc news. i'm simon pusey. our top stories. president biden tells us citizens to leave ukraine now, warning "things could go crazy quickly" britain's most senior police officer, cressida dick, is to step down after the mayor of london said he had no confidence in her leadership. canadian truckers block more border crossings to the us in their protest over covid restrictions, with the economy now counting the cost. a coronavirus scare for the queen. prince charles tests positive two days after meeting the monarch. as with all the medical or health related matters, buckingham palace is saying the absolute minimum. all the royal sources will say is that the queen is not displaying any

symptoms of covid. welcome to our viewers on pbs in america. and around the globe. in the past few hours, president biden has called on all american citizens remaining in ukraine to leave the country immediately. with russia continuing its military build—up along its border with ukraine, mr biden said that he would not send troops to rescue americans, if moscow invaded. this is what he said in an interview with nbc news. look, what i have asked is american citizens should leave, should leave now. we are dealing with one of the largest armies in the world and it's a very difficult situation and things can go crazy quickly. president biden. well, the leaders of the three baltic states have called on nato allies to increase military support in eastern europe, amid the heightened tension.

the call comes after britain's foreign minister, liz truss, held what have been described as "frosty talks" with her russian counterpart, sergei lavrov. this report from the bbc�*s steve rosenberg in moscow. for liz truss, the day began by the kremlin at the tomb of the unknown soldier, a sign of respect for russia before the difficult diplomacy. she's only been foreign secretary five months. sergey lavrov has been in the job 18 years. a big difference. and there were major differences of opinion. mr lavrov called western politicians "indoctrinated", the british diplomats "unprepared", and on the subject of ukraine... translation: the conversation we had was like a deaf person i talking to someone who's mute.

we were listening to one another, but not hearing each other. i certainly wasn't mute i in our discussions earlier. i put forward the uk's point of view on the current - situation and the fact thatl as well as seeking to deter russia from an invasion - into ukraine, we are also very resolute in pursuing| the diplomatic path. what we saw here today was diplomacy without any of the diplomatic niceties. no hint of compromise. instead, a very public clash between britain and russia over ukraine and over the whole question of european security. it's moscow's military activity near ukraine that's causing concern in the west, like joint drills involving russia and belarus. but mr lavrov insisted russia has no plans for an invasion. it does stretch credulity that there are no plansl when there are 100,000 troops

lined up on the _ ukrainian border. so we need to see those words from sergey lavrov translated i into action of de—escalating and moving those troops i away from the border. it feels a little bit as if it's france and not the uk which is a leading diplomatic efforts. and we had president macron in moscow this week. is it the case that the uk is sort of playing catch—up here or playing second fiddle? it's very important that - france, the united kingdom, germany, the united states and all of our allies - are involved in this effort. this is not about alternatives — this is about all— working together. but russian state tv has been working against liz truss, calling her "clueless", "incompetent". i think when people resort to personal attacks, - it's when they have no good political argument to make. this was the first visit

by a british foreign secretary to moscow for more than four years. is that called soft power? but after a day of very public disagreements, uk—russian relations feel as frosty as ever. steve rosenberg, bbc news, moscow. let's speak to consta nze stelzenmuller, who's a senior fellow in foreign policy at brookings institution. she's in washington. serghei marghiev attempt to saying it was like a conversation with a deaf person and liz truss responding in kind —— serghei marghiev attempt to. how difficult is this language when it comes to europe and russia?— europe and russia? good evening- _ europe and russia? good evening- it _ europe and russia? good evening. it seems - europe and russia? good evening. it seems to - europe and russia? good evening. it seems to me | europe and russia? good - evening. it seems to me that russian diplomats have been uniformly bruised and rude to all of the european diplomats they've encountered. remember that in the press conference

between president macron and vladimir putin, putin actually lied to the president by saying that russian mercenaries in mali were not supported by the russian government and the world knows the truth is otherwise, so liz truss did not get treated any differently than anyone else, i fear. so she wasn't _ than anyone else, i fear. so she wasn't treated differently? would you say there is a united response within the nato countries to russia at the moment?— countries to russia at the moment? ~ , , ., moment? absolutely. there have been all the _ moment? absolutely. there have been all the stories _ moment? absolutely. there have been all the stories about - been all the stories about disunity but i think that's wrong. there are some legitimate disagreements on difficult questions about when sanctions are triggered and when to maintain them and be proportional but the truth is that the machine rooms of policymakers have been coordinating this for weeks and months now even the european union where the russian foreign ministry had sense letters to

each european member individually saying we won't accept an answer from you if you don't send them separately as individual countries and refused to do so and instead the eu foreign minister sent an answerfor the eu foreign minister sent an answer for the the eu foreign minister sent an answerfor the entire the eu foreign minister sent an answer for the entire union, the eu foreign minister sent an answerfor the entire union, so i would say there is unity. borisjohnson i would say there is unity. boris johnson saying i would say there is unity. borisjohnson saying earlier that neato needed to have a package of sanctions ready if needed. does such a package exist yet?— exist yet? nato doesn't have sanctions. — exist yet? nato doesn't have sanctions, it _ exist yet? nato doesn't have sanctions, it doesn't - exist yet? nato doesn't have sanctions, it doesn't do - sanctions, it doesn't do economic sanctions. it is the military arm of the western alliance and i'm being very precise and specific here but there are american sanctions and european sanctions which are coordinated if we want to be completely precise and that is something that has been worked on for months and he's describing something that has already happened. it describing something that has already happened.— already happened. it will be interesting _ already happened. it will be interesting to _ already happened. it will be interesting to see _ already happened. it will be interesting to see what - already happened. it will be - interesting to see what happens next and of course every day new things come and at the moment russia is being accused of not letting them into the

sea to practice war craft but that's all we've got time for, thank you very much indeed for that. ., . , thank you very much indeed for that. ., ., , . ., that. you are very welcome. cheers- _ britain's most senior police officer, the chief of london's metropolitan force, has resigned. cressida dick is leaving the post two years earlier than expected after the mayor of london expressed reservations about her ability to reform the police force. a recent police watchdog report into misconduct found evidence of racist, anti—semitic and homophobic behaviour. june kelly reports she made history when she became the first female commissioner of the country's largest force. but tonight, cressida dick's long policing career was brought to a sudden end. following contact with the mayor of london today, it is quite clear that he no longer has sufficient confidence in my leadership of the metropolitan police service for me to continue as commissioner. he has left me no choice but to step aside. the mayor, sadiq khan, had

already put out his statement. it's clear that the only way to start to deliver on the scale of the change required is to have new leadership right at the top of the metropolitan police. what would be a decisive day on the job for cressida dick began at the bbc, and a radio phone in. responding to a grilling about her performance, she pledged her determination to carry on. i have absolutely no intention of going. 2a hours earlier, the mayor of london, sadiq khan, had issued an ultimatum. my expectation is the next time i see her i want to see what her response is. but their working relationship is over. the finale to a torrid 12 months from the met. it was almost a year ago that one of their own officers, wayne couzens, used his police powers to kidnap sarah everard off a london street and then

rape and murder her. with a killer policeman under arrest, as women gathered for a vigil in memory of sarah, these were the images which went viral. more bad headlines for the met. the reputation of the met| was much more important than the people she was meant to serve. - by not admitting that there are deep systemic issues, i they are not going to be able to solve them. _ while pressure has been building on cressida dick, a few months ago politicians gave her more time, with priti patel extending her contract. now the behaviour at number 10 has led to the partygate investigation, but even in this, the met has gathered more criticism for being flat—footed in its response. and then, in recent days, shocking messages sent by some officers at charing cross police station lifted the lid on racist and sexist attitudes which were redolent of policing in the 1970s.

in a separate scandal, two officers regarding a murder scene where two sisters had been killed also sent abusive messages. those officers ended up in prison. after five years at the helm, cressida dick will soon be leaving scotland yard for the last time. the murder of sarah everard and many other awful cases recently have, i know, damaged confidence in this fantastic police service. there is much to do, and i know that the met has turned its full attention to rebuilding trust and confidence, and to raising our standards. tonight, the home secretary paid tribute to dame cressida. she began the job as a popular pioneer, but her tenure has ended with her losing the faith of both the politicians and the public.

all abandoned wells in morocco are to be surveyed following the tragic death of a five—year—old boy earlier this week. rayan's plight at the bottom of a narrow, 32 metre deep borehole, gripped millions of people in the country, and beyond. a water ministry official said the survey was designed to prevent a repeat of the tragedy. those who have dug wells which flout regulations will be required to pay to make them safe. now to canada, where the chaos caused by the trucker protests is spreading. two us—canada border points have been affected, including the ambassador bridge, one of the most important trade corridors between the two countries. car makers say it's affecting production. samira hussain has the latest from ottawa. if there is any sense that this is going to resolve sometime soon, that doesn't seem to exist. from a lot of the people i've spoken to share over the past several days, the resolve to stay here for the long term it's

really quite strong. so, from a police perspective, it does pose some sort of challenge, how do you actually get this crowd to disperse in a peaceful kind of manner while making sure everyone is back safe. this protest may have started in ottawa almost two weeks ago, it has spread to other parts of the country and most crucially, to canadian land borders with the united states, some of those land borders are responsible for more than 20% of trade between the two countries. and that is why you're hearing from a lot of american politicians and canadian politicians urging from the blockades, more specifically near the border to be opened up. we're sharing this wave of solidarity and process meanwhile, france and belgium have promised tough action to prevent planned protests this weekend, along the lines of those in canada. motorists intending to block

roads into the french capital to show their anger about coronavirus restrictions have been threatened with fines and jail terms. we can speak to stephanie carvin, a former national security analyst, and now, associate professor at ca nada's carleton university. how would you rate the government response to these protests that appear to have become common quickly out of control? �* , ,., , control? it's mind-bogglingly bad. control? it's mind-bogglingly bad- from — control? it's mind-bogglingly bad. from the _ control? it's mind-bogglingly bad. from the beginning - control? it's mind-bogglingly| bad. from the beginning they seem to have misunderstood the nature of this movement, which, of course, has been driven by extremists who turned to extremists who turned to extremist tactics and then seem to be stunned and had no response and that municipal level in ottawa they have tried to say there is no policing solution and federal involvement required but at the federal level they have said that this is a police matter and while they will support police and provide additional resources they don't want to get involved. and at least where i live in ontario government has been largely absent in the first major action they took was a few

hours ago when they have moved to try and stop or at least freeze the money and some of these large crowdfunding campaigns we've seen that, honestly, the government seems at a loss to ask and they are suffering as a result.- at a loss to ask and they are suffering as a result. you talk about crowdfunding _ suffering as a result. you talk| about crowdfunding campaigns but how significant have they been to the movement which seems to be building in many cities? �* , ., �* cities? it's not something i'm sure we've — cities? it's not something i'm sure we've seen _ cities? it's not something i'm sure we've seen before - cities? it's not something i'm sure we've seen before in - cities? it's not something i'm sure we've seen before in the sense that these crowdfunding sites are a vehicle for movements, and some of the crowdfunding platforms have been associated with funding extremist movements before but in this particular case we seem to not only have the crowdfunding website being used to raise money but it's also become a symbol of resistance, like in energy. i probably wouldn't be on bbc now if this campaign had only raised $50,000 and in this sense it's become what has become the

focal point and energy so even in the thick stream list movement and convoy doesn't get their hands on the money, these crowdfunding platform serve extremist ends by giving money and perpetuating the situation in canada. it’s and perpetuating the situation in canada. 3 ., and perpetuating the situation in canada. �*, ., , and perpetuating the situation in canada-— in canada. it's not 'ust canada is seems * in canada. it's not 'ust canada is seems to h in canada. it's not 'ust canada is seems to be _ in canada. it's notjust canada is seems to be spreading - in canada. it's notjust canada i is seems to be spreading around the world and in france we here in paris in the next few hours and australia and new zealand. do you see it spreading further or it will fizzle out? it’s or it will fizzle out? it's auoin or it will fizzle out? it's going to _ or it will fizzle out? it's going to be _ or it will fizzle out? it�*s going to be interesting to see as they were attempts in canada to set up convoys and other city and toronto and quebec city, they knew a convoy delegation, i suppose was coming into their cities and they took appropriate actions and were able to manage it and not allow the vehicles to get entrenched and i have no doubt that the brazilian authorities are used to dealing with large—scale protests so i hope they are prepared in a similar way and can avoid the situation that ottawa is in but if you go on the facebook pages and you

watch the live streams there is so much international support for the movement. let's face it. canada is normally not that interesting of a country so i think this movement is bolstered by the perception that there is widespread international support for it and, effectively, they are exporting their model of protest to other countries. potentially the other countries might have a bit of preparation ontario didn't. and thank you so much forjoining us.- so much for “oining us. thank ou. stay with us on bbc news, still to come india's row over the hijab in schools and colleges continues. there's mr mandela, mr nelson mandela, a free man taking his first steps into a new south africa. iran's spiritual leader, ayatollah khamenei, has said

he's passed a death sentence on salman rushdie, the british author of a book which many muslims say is blasphemous. the people of haiti have flocked to church to give thanks for the ousting of their former president, ba by doc duvalier. because of his considerable value as a stallion, - shergar was kept in a special secure box in the stud - farm's central block. shergar was driven away. in a horse box the thieves had brought with them. there stepped down from the plane a figure in mourning — elizabeth ii, queen of this realm and all her other realms and territories, head of the commonwealth, defender of the faith. this is bbc news. the latest headlines.

president biden tells us citizens to leave ukraine now, warning "things could go crazy quickly" britain's most senior police officer is to step down after the mayor of london said he had no confidence in her leadership. educational institutions in the indian state of karnataka will begin to re—open from monday after being closed in a row over the banning of the hijab in classrooms. rival protests erupted into violence after students were told they could not wear the traditional islamic head—dress during lessons. the bbc�*s divya arya has more. muskaana wears at home what brought so much tension at college. she's the most recent emblem of india's politics of the hijab. i just saw a crowd of youngsters who were wearing shawls. i was just passing. but then, they all started attacking me. and they were telling me, go back, you are not allowed to the class by wearing burqa.

and they were coming and they are also telling me to remove this and go back. it was one front in a wekk of of an escalating row. over whether people can wear this in classrooms in the southern state. where demand for islamic headdresses were met with protesters wearing saffron shawls, a symbol of hinduism and the respective slogans came to the fore. i was angered and scared and then i shouted sol shouted "allahu akbar! " so that i get courage. i get power— so that i get courage. i get power from allah. she still went to college. something women say they been doing in the past wearing hijabs. despite state—sponsored words to the contrary. women started wearing the hijab in school, we complained that we have a right to decide on the uniform and according

to the state education act of 1995, the institution has the right to prescribe the uniform and students must follow it. she also cited state high court judgments backing it up. now they have to decide on the latest dispute. cited judgements by quarter. now they have to decide on the dispute. this college is one of many in the state for students wore saffron scarves to protest women's believed where head scarves. to diffuse passions while they wait for the court to come to a decision. critics say the state administration has done little to engage the students in dialogue. instead, allowing opinions to polarise. polarisation that has led to, at times, violent protests across the country. that's about more than outward appearances. particularly for india's

200 million muslims. who, while great in number, are a minority. the karnataka authorities of prevented gatherings of more than four people. but that does not stop off in a hostile debate from flourishing online. humbly, please, do not update the status as hindu versus muslims. not only for us, not for the non—muslims and muslim girls, everyone should stand for their right. online and in real life, rights and beliefs are in a painful confrontation. the french virologist, luc montagnier, who won the nobel prize for medicine for his co—discovery of the virus that causes aids, has died at the age of 89. stephanie prentice reports. he was the man who helped tackled the fear, damage and death spreading through the 1980s as the aids epidemic

unfolded around the world, baffling scientists. the virus can be passed during sexual intercourse with an infected person. luc montagnier isolated human tissue from a neck gland in 1983 and was able to draw the link between a virus in it and aids. he battled to be recognised as the first scientist to reach this conclusion, eventually receiving a nobel prize recognition in 2008 for his work. it is a frequent statement saying that nobel prize winners are less productive after receiving the nobel prize, so i will try not to show this. he went on to develop a specialism in exploring cures for viral diseases but also became a pariah within the medical community for supporting non—scientific theories. in 2020, this translated to a popularity with modern anti—vaccine movements as he

denounced covid vaccines and claimed covid—19 was made in a lab. despite this, tributes are pouring in with love from his work and with love from emanuel macron for his contribution to the fight against aids. here in the uk, prince charles has tested positive for covid for a second time, and is self—isolating. it's understood he met the queen just two days ago, but a palace source says she hasn't been displaying any symptoms. a warning, there are flashing images in this report from our royal correspondent, nicholas witchell. .. the british museum in london last night, a reception for the british asian trust and the guest of honour prince charles and his duchess, the duke of, and his duchess, the duke of, and everyone was shaking hands freely and amongst the guests that the prince shook hands with was the chancellor, rishi sunak and roughly 12 hours after the pictures were taken, charles took a routine covid cove in test and it's the

second time he's caught it and he is triple vaccinated and thought to be coping well. but two days ago he was presiding at an investiture in windsor castle and while he was there he met the queen. she had just returned from sandringham where she had been seen in good spirits at the weekend, marking the 70th anniversary of her accession to the throne, so inevitably, a concern. might she have contracted covid during the meeting with the prince of wales? as with all medical and health—related matters, buckingham palace is saying the absolute minimum. all the royal sources will say is that the queen is not displaying any symptoms of covid. it can safely be assumed that the queen has been triple vaccinated, but it's not known whether she has been tested for covid or what any such tests have indicated. all the palace will say is that the situation is being monitored.

hello again. this time yesterday we were looking at some hill snow in scotland causing a few issues on some of the higher scottish roots and some strong winds gusting at 70 mph in the western isles but a cover of show left over the hills and this was courtesy of this area of cloud, the low pressure currently working across the north sea to bring some fairly windy weather to the netherlands through friday. in the atlantic, we have the next weather system waiting to come into the start of the weekend but between that and that, we get that, an area of high pressure that will be bringing some fine weather our way for friday. however, over recent hours, as the high pressure has edged in, the number of showers has dwindled and a few left in

north—western areas and with the combination of clear skies and light winds allowing a widespread frost, there could be a few icy patches around and the lowest temperatures in aberdeenshire getting down to 10 celsius and a freezing cold start to the day on friday but beautiful winter sunshine for most of you through most of the day, and some isolated showers across the north west and through the day you will see the weather turn cloudy in northern ireland. temperatures? we are looking at highs close to the seasonal average, about six in glasgow and nine for cardiff and london. there will be rain developing on friday night and into saturday the rain will affect parts of england and wales but doesn't reach the south—east of england and east anglia, where it will stay bright and breezy but there will be strong winds for many of us and for scotland and northern ireland, frequent showers and some bright spells between the showers. temperatures a little bit higher, between eight and 10 degrees making it a mild day but perhaps not feeling so given the strength of the winds. talking of winds, the next

area of low pressure on sunday looks also set to bring more wet and windy weather our way. the rain might end up further northwards but not reaching northern scotland where there will be showers around but otherwise the rain will be heavy and it will be a windy day with gales across southern parts of england and wales and through the english channel gusts of around 50 or 60 miles an hour, strong enough to bring down a few tree branches and there might be localised disruption on sunday from the system. next week looks unsettled, often wet and windy, but it does turn very mild for a time. that is your weather.

in canada, protests over coronavirus restrictions led by truckers are growing. there are blocks and delays on at least three land border crossings into the us, including one of the most important trade routes over the ambassador bridge. car makers say its affecting production. in afghanistan, a number of women who've

participated in protests demanding women's rights are still missing. the taliban denies it's holding them, and says a general
