this is bbc news. i'm lewes vaughanjones with the latest headlines for viewers in the uk and around the world. thousands are arrested in russia as supporters ofjailed opposition leader alexei navalny take to the streets. these scenes of riot police and detention suggest the kremlin is more worried than he's letting on. pharmaceutical company pfizer comes under fire for coronavirus doses. a night—time curfew begins in the netherlands in an effort to contain the virus. and, tributes are paid to larry king, the american broadcaster and talk show host, who has died aged 87.

hello and welcome. the united states, the european union and the uk have condemned authorities in russia after police there detained more than 2,000 people at protests in support of the jailed opposition leader, alexey navalny. large gatherings took place across russia, including the eastern cities of vladivostok and khabarovsk. in the siberian city of yakutsk, protesters braved temperatures of —50 degrees. the main demonstration was in the capital, moscow, from where our correspondent steve rosenberg reports. in moscow, you can feel the anger. police had warned people any protests would be broken up, any protester risked arrest. but thousands came to pushkin square to support the kremlin�*s fiercest critic, alexei navalny.

"freedom to navalny," they cried. and, "russia without putin." on her way to the protest, mr navalny�*s wife, yulia, was detained by police. so were hundreds of others for taking part in what the authorities called an unsanctioned gathering. for years, the russian authorities made out that alexei navalny had minimal support across the country, that he was in no way a threat to them, but these scenes of riot police and detentions suggest the kremlin is more worried than they've been letting on. in a direct challenge to vladimir putin, whom he accuses of ordering the nerve agent attack on him, alexei navalny returned to russia last weekend and was arrested for an alleged parole violation. russia isn't investigating his poisoning, it's investigating him. the kremlin denies any

involvement in the attack. there were pro—navalny rallies across russia today. things heated up in vladivostok. in yakutsk, it was —50, but there were protests here too. but the kremlin rarely gives in to pressure, especially from the street. instead of compromise, expect a crackdown. steve rosenberg, bbc news, moscow. zhanna nemtsova is the daughter of the assasinated russian opposition politican, boris nemtsov. she took part in one of today's protests in nizhny novgorod, in central russia and spoke to us a little earlier. ijoined the marches to honour my father, and i was very much surprised with the numbers. ithink... it's difficult to estimate, but i think around 10,000 people took to the streets today. lots of young people.

and i guess that it is the biggest growth ——and i guess that it is the biggest protest since the early 90s, and all protesters were very peaceful and i'm very much proud of my fellow citizens. i was not afraid, i was ready for everything. i was ready to be detained, i was not. there were some detentions. for example, the head of navalny�*s office was detained earlier in the morning. he was not able to join the protest here. there were some other detentions, but i was not afraid at all. i was ready. i think putin is of course, very much afraid of those crowds that we saw today. not only in moscow, all over

russia, and i don't know what his response might be to these protests. but i think that many people today took to the streets not because of politics, but it was a purely moral choice for them because they saw what had happened to alexei navalny. it was completely unlawful, this trial that he had and the fact that he was detained. and also that he was, there was an attempted poisoning with a nerve agent and he managed to survive. he is my friend, so i'm very worried about him. i want him to be russia's president, that's what i want.

thousands of people have joined demonstrations across brazil to demand the resignation of presidentjair bolsonaro. protesters say he hasn't done enough to tackle the coronavirus pandemic and blame him for the slow rate of vaccinations, which only started last week. more than 215,000 people have died of covid—i9 in brazil, the second highest numberin the world. car and bicycle rallies were held in cities across the country, including rio dejaneiro and sao paulo. the situation is particularly bad in amazonas state, where oxygen shortages caused the deaths of around 100 patients who contracted a new, more contagious strain. the us immunisation programme has been thrown a curve ball by pfizer. it says six doses of vaccine can be extracted from every vial supplied to pharmacies, rather than the five previously announced. the new york times says the us drugmaker now plans to provide fewer vials to meet its committment to supply 200 million

doses by the end ofjuly. aaron kesselheim is professor of medicine at harvard medical school. he says pfizer's known about this for a while. it was discovered a few months ago that using special tools, certain pharmacists are able to extract an extra dose out of the normal shipment of five vials, and had been doing that to try to vaccinate more people. so, in response to that, pfizer is now officially saying that you can get six doses out of a pack and is saying that that will now count towards its responsibility to provide certain doses under the us contract. this allows pfizer to finish its commitment for the current doses, which at selling in about $19—20 a dose. then to sort of, you know, negotiate the next contract or some other contract more quickly than it

would have before. senior doctors in the uk have called on the government to shorten the gap between the first and second doses of pfizer—biontech coronavirus vaccinations. the doctors union, the bma, called the gap of a maximum 12 weeks "difficult to justify" and said it could potentially undermine the effectiveness of the jab. however, the government argues it could save lives by allowing more people to receive a first jab more quickly. 0ur health correspondent anna collinson reports. they're used to taking care of others, but they're now the ones being looked after. today, thousands of health and social care workers, like here in glasgow, have been receiving their coronavirus vaccine. just get the vaccines out. obviously, do your dosage counting. and from scotland to south wales and the llyn peninsula, this pilot aims to reach those who are unable to travel to the larger sites. very pleased and looking forward to the next one.

but while the roll—out rolls on, so do questions about the gap between the first and second dose. as pressures intensified on hospitals in december, the dosage gap was extended to 12 weeks. the uk's chief medical officer said millions of the most vulnerable were more likely to become severely ill without a jab, and this was the best way to reach more of them quickly. but some senior doctors want the intervalfor the pfizerjab reduced to six weeks. that would still allow many more people to have a first dose, compared to a three—week interval, but at least it would be in keeping with international best—practice guidance. there is no other nation internationally that has adopted a 12—week delay. data suggests the 0xford—astrazeneca vaccine is still effective when doses are given 12 weeks apart, but pfizer only has data for the first three weeks. even so, many scientists have defended the uk's current approach, calling it "a balance of risks".

i totally support the decision to extend the gap between doses. i think, looking at the evidence in total, i think that is strongly supportive of that. and i think on this particular occasion, the bma has probably got it wrong. ministers say the current process is the right move and will be particularly keen to reassure anyone who has concerns. this mosque in birmingham is the first in the uk to become a vaccination centre. one more measure to try and reach the most vulnerable. anna collinson, bbc news. italy is accusing pfizer and astrazeneca of serious contract violations, after the drugmakers said they wouldn't be able to deliver the agreed amount of coronavirus vaccine on time. prime minister giuseppe conte, says the delays are unacceptable, and doing enormous damage to italy and other european countries. he says the government will use all legal means to make sure the companies

meet their obligations. the two companies say production problems have forced them to more than halve the amount of doses they can deliver. a night curfew has come into force in the netherlands — as part of further measures to contain the coronavirus. anyone outdoors will need a valid work reason, or it must be an emergency. anna holligan reports from the hague. this is stay at home between 8:30pm in the evening and 4:30am local time. this is designed to try to end the social gatherings. so since the bars and restaurants closed last month, there has been a real increase in house parties, underground raves. and then exceptions to this rule exist. so you can go out if there's an emergency or if you have a valid work reason. also, if you are attending a funeral or court proceedings or traveling into or out of the country. the one other exception

that exists is you can have a dog on a lead, and actually, there has been reports in a real increase in the number of people who are signing up for to offer to our people's dogs as a way to try to get around these curfew rules. on top of this, the flight ban has just come into force. so this is affecting flights from areas considered to be high—risk, where the new strains of the virus were first detected and are spreading rapidly. so, no more planes for at least a month from the uk, south africa and south american countries. that would be at least a month, or it until they change the legislation here so that they can make the ten day quarantine rule obligatory for anyone arriving in the country. britain's prime minister, borisjohnson, has spoken tojoe biden, in what appears to be the new us president's first conversation with a european leader, since he entered the white house on wednesday. the two spoke on the phone earlier, as our political correspondent, chris mason explains. i'm told that the call this evening was the first call that president biden made

to a european leader. and the real focus was on climate change. so president biden has committed the us to re—signing up to the paris agreement on climate change, committing the country to net zero emissions by 2050. and this matters in the context of climate diplomacy in the uk at the moment because the uk will be chairing that cop 26 summit on climate change, united nations summit in glasgow in november. so whats�*s the view across the pond? well, the bbc�*s washington correspondent nomia iqbal explained why speaking to a new us president is considered a badge of honour amongst world leaders. whenever there is a new president, everyone wants to get in there as quickly as possible to make their case, to try to get lots of deals, and the statementjust reading in front of me, it's a very warm statements, as you can imagine. borisjohnson congratulating joe biden on his victory and touching on lots of issues as chris mentioned there, climate change. what really stood out for me,

however, were talks of a trade deal which is hugely important to the uk as we know because the uk has left the european union and wants a trade deal as soon as possible. in fact, in the statement, the words as soon as possible were written in terms of discussing the benefits of a potential free—trade deal. those are the words used in the statement. the truth is that that the biden administration has said that its priority is americanjobs and infrastructure, and the incoming treasury secretary has emphasized that point many times that that is what they want to focus on, not trade deals. and that's surely going to cause huge anxiety for the uk, which, quite frankly, wants a trade deal as soon as possible. this is bbc news, our main headline... russian police have arrested thousands of people — in dozens of cities across the country — to halt protests in support ofjailed opposition leader alexei navalny.

well our moscow correspondent sarah rainsford was at the protests in the russian capital. here's her take. a big crowd crammed into pushkin square and into all the streets around, but there was a huge presence of riot police there as well, right at the beginning, they were swooping in and grabbing people pretty much at random from the crowd, detaining them, and then they left everyone, sort of, milling around for a couple of hours. people chanting, "freedom from to alexi navalny," calling for his release, chanting against vladimir putin as well. a really defiant crowd that turned out, but after a couple of hours, it seems that the police basically lost patience with the crowd. the crowd started pushing and shoving. there were scuffles, there were altercations, there were a few of players that went off as well, there were a few of flares that went off as well, and eventually, the riot police are pushed the main crowd back from the square and began to clear the streets.

and we now know that hundreds of people have been detained across russia, some 2000 at the latest count, in what is obviously the beginning of a crackdown on this act of resistance, basically, by supporters of alexi navalny. thanks to sarah there. the american talk show host larry king has died. in a career spanning six decades, he made his name at cnn interviewing some of the biggest names in politics, showbusiness and sport. daniela relph looks back at his life. for more than 60 years, he interviewed everybody who was anybody. tonight, the legendary liza minnelli, on marriage. would you marry again? are you nuts? from oscar winners to presidents. the decision to move saddam. hussein was the right decision. if you were in the public eye, you came to the court of larry king. it's the witching hour! born in brooklyn, he began his career in radio. from the nation's capital, you're listening to the larry king show. by the 1970s, he was

broadcasting his late—night show coast—to—coast. across the united states, i this is the larry king show. then, in the 1980s, kingjoined a new 24—hour tv news station, cnn, where he heard an early denial of political ambition. i have no intention of running for president, but i'd like the point to get across that we have a great country, but it's not going to be great for long if we're going to continue to lose $200 billion a year. his style was to gently probe and to not hit hard. i learned that the more i drew back, asked good questions, listened to the answers, cared about the guest... the biggest compliment you could get, as sinatra once said, "you make the camera disappear". larry king was married eight times and was presenting shows well into his eighties. an interviewer of enormous influence... the cut!y'go, "cut! ..he said he never prepared too much and liked

the conversation to unfold. i am nowjoined by casey adams. he runs a podcast and interviewed larry recently when he wasjust 19. he's in los angeles. thanks so much for coming on the programme.— the programme. thank you so much for _ the programme. thank you so much for having _ the programme. thank you so much for having me. - the programme. thank you so much for having me. it's - the programme. thank you so much for having me. it's my l much for having me. it's my pleasure. much for having me. it's my pleasure-— pleasure. larry, as so many know him _ pleasure. larry, as so many know him just _ pleasure. larry, as so many know him just by _ pleasure. larry, as so many know him just by his - pleasure. larry, as so many know him just by his first i know him just by his first name, an absolute institution. we are used to watching him ask the questions, of course, you had amount of podcast where he was answering the questions. what was that like?— what was that like? yeah, it was such _ what was that like? yeah, it was such a _ what was that like? yeah, it was such a pleasure. - what was that like? yeah, it was such a pleasure. you . what was that like? yeah, it - was such a pleasure. you know, i've had a podcast for the last three years and interviewed hundreds of entrepreneurs, but my interview with larry king was so special to me because we took 45 minutes and he was just coming off his stroke back in 2019, and ijust remember sitting down with him and when the cameras turned on, he was so sharp. but most importantly,

before the podcast, he was curious about me, he was asking me questions about what i was working on and my goals in the broadcasting world. most importantly, he genuinely cared about our —— conversation, and it was one of the most impactful conversations about his legacy come about him being a father, advice to young entrepreneurs, and just the fact that he took the time of day to sit down with me, this 19—year—old kid from virginia that has a podcast was not on the inspirational, but something that deeply impacted my life moving forward. i’m my life moving forward. i'm sure. my life moving forward. i'm sure- this— my life moving forward. i'm sure. this is _ my life moving forward. i'm sure. this is someone who has obviously been around for decades and decades before you were born. you can't have seen a lot of his stuff. so what is it that you admire about him? yeah, i would say anyone watching the snow is larry king, even my generation. i'm 20 years old right now, growing up, you would always see and hear about larry king. you know, he was born in 1933, was born in the year of 2000, we

have a 67 year age gap. i think one of the most impressive things that i learned from him was what he talked about when it comes to his quote, it says, "i've never learned anything while i was talking." and he talked about the value of listening and having curiosity into every conversation that you are in. and that has been something that long before i ever met larry, he was a mentor to me and someone i looked up to me and someone i looked up to as a 17—year—old kid starting a podcast and doing interviews. i took that principle early on when it comes to writing down notes questions, leading each conversation with curiosity and most important, listening to the person you're talking to. and it's led me to not only hundreds of interviews but led me to meeting and tabulate —— having larry king on my show. like i said commit was not only a pleasure but a lesson i will always remember. it a pleasure but a lesson i will always remember.— always remember. it is something _ always remember. it is something that - always remember. it is something that he - always remember. it is. something that he made always remember. it is something that he made look so easy, the lack of preparation, not preparing too much, being

in the moments, but of course, many people have done that through the years, and it doesn't work out so successfully. he found that winning formula, didn't he? absolutely. i think even on my own show, i started out writing down questions and trying to prepare. i rememberwatching down questions and trying to prepare. i remember watching an early interview with larry and the way he would cut people off and continue the conversation without any questions written down was a testament to how great he was as a broadcaster. and i remember the day i watch that interview and i said, "i will never write on a question again and i will lead each conversation with curiosity." and it has paid off well for me. and like i said, it is a valuable lesson that i believe anyone watching this can take away, which is, be curious about every single person you come in contact with. make sure to learn something, each conversation you're having with another individual, whether an interview or in everyday life, and i know that lesson will forever stick with me. that's

really impressive. _ forever stick with me. that's really impressive. and - forever stick with me. that's really impressive. and it's i forever stick with me. that's| really impressive. and it's an era going, isn't it? because back then when there was limited outputs or celebrities to get their messages out, those big primetime interview shows, larry, you know, striding away, but now, you are an example, there are podcast errors and so many other ways, that air of broadcasting seems to be changing. absolutely. i asked larry king, how have we stayed relevant in on top of the game over the last six decades? and something that he told me, he said, "i never followed the technology. i let the technology follow me." and i remember the first time i met chance king, his son, who i had dinner with and my good friend introduced me to him, and when we were talking, he talked about, you know technology, and i was dad wanted to start a podcast and how he was always working on the next thing and how he was staying very motivated about

his craft, which was broadcasting. and i think is not only taken huge steps in the broadcasting world, but he's inspired some of the people all over the world, including myself to focus on great interviews to build a platform, to stay curious, but most importantly, to stay humble and love what you do, and that's what larry definitely taught me. and that's what larry definitel tau~ht me. ., , , definitely taught me. 0k, casey adams, definitely taught me. 0k, casey adams. great — definitely taught me. 0k, casey adams, great to _ definitely taught me. 0k, casey adams, great to have _ definitely taught me. 0k, casey adams, great to have you - definitely taught me. 0k, casey adams, great to have you on. i adams, great to have you on. good luck. adams, great to have you on. good luck-— adams, great to have you on. good luck. while the covid pandemic has been shutting down events and gatherings, one tournament is ploughing on. tennis players from across the world have flown to melbourne for the australian open that begins on sunday — but their experience has been very different to normal. here's grigor dimitrov, ranked 19th in the world. making the most out of it. i was one of the fortunate ones that was on a flight that didn't have any cases. so, you know, trying to make the most out of it. getting out there, playing some

hours, getting some air, i think, is pretty much the most important thing right now. it's vital for us to keep on moving, to keep on, you know, getting to be as solidified on the opportunities that we get on every single day. and, yeah, just going one day at a time. it's very different. clearly i would say... i want to say that it's going to be ok, because i'm being supportive as much as i can. and i definitely feel for the players that have to be in their room for a couple of weeks. and that's definitely unpleasant. i mean, i can only imagine — i had the virus and i was at home for three weeks. but at least your home. now you're stuck in a room, and that doesn't really add up to your preparation. but hopefully after that, you get a little bit of time to kind of get your settings right, so to speak. ijust think right now, it's

very different and difficult for everyone to the sort of find the right, you know, like grit, so to speech. i think also a lot of them are trying to make the most out of their room. and, as i said, the most important thing for us is to move and get some fresh air in the sense that i would say that's what i think the biggest confrontation is for them at the moment. to be honest, there was something in the making, that was grigor dimitrov. that's it for me. i will be back with the headlines in a few minutes' time. i am on social media. you can reach me on twitter — i'm @lvaughanjones. this is bbc news. bye—bye.

hello. after one of the coldest nights of the winter so far, sunday brings some significant and disruptive snow to parts of england and wales, for some of us in northern ireland as well. very cold, frosty start to the day, icy patches, a few fog patches out there too and an area of sleet and snow initially for southwest england, parts of wales, northern ireland, but will push further east across southern england towards the southeast across the midlands during the day as well before stalling and then just pulling away southwards on into sunday evening and clearing. this is ten o'clock in the morning, though. southwest england, sun may brighten up here with a few wintry showers, but as the snow moves eastern within the zone of falling snow here, and again into parts of northern ireland, several centimeters, even to low levels, more into the hills, so certainly some difficult travel conditions. northern england and scotland seeing some sunny spells,

a scattering of winter showers towards the northwest of scotland. but it is scotland, northern england, northern counties of northern ireland that see sunday's driest and sunniest weather. but for the rest of england into wales, southern parts of northern ireland, cloud, some outbreaks of snow here, again, some difficult travel conditions, some uncertainty about how far north into the midlands, and perhaps east anglia, the snow is going to reach, we've got to watch that as well. temperatures just hovering close to freezing, where you have got the snow. get some sunshine around, 2—4 celsius. the outbreaks of snow gradually clearing away during sunday evening. icy conditions following on behind, we've got the showers pushing in towards scotland, perhaps northern ireland and northern england. icy in places going into monday morning. another widespread frost as monday begins, one or two fog patches potentially towards south east england. some sunshine on monday, plenty of winter showers towards northern and western scotland, a few for northern ireland, north—west england, north wales.

some will push a little further south eastwards during the day, but driest and sunniest towards the south and east of the uk on what will be another cold day. and then it changes. tuesday, weatherfront from the atlantic coming into the cold air. so, again, further rain, sleet and snow pushing northeastwards, then further weather fronts coming our way from midweek, introducing milder atlantic air, but the winds are going to pick up, and we will see further spells of rain. so all parts from midweek will be turning milder, but also windier and wetter. and if you're in a flood—affected area, that's something you're going to need to follow very closely as we go through the week ahead.

this is bbc news, the headlines... russian police detained more than 2,000 people at protests in support of the jailed opposition leader, alexei navalny. large gatherings took place across the country, from moscow to vladivostock. riot police dragged away demonstrators who pelted them with snowballs. navalny was almost killed in a nerve agent attack last year. pharmaceutical company pfizer has come under fire for the dosage of its coronavirus vaccine. the new york times says the us drugmaker now plans to provide fewer vials to meet its committment to supply 200 million doses by the end ofjuly. the netherlands has imposed a night—time curfew in an attempt to control the spread of the coronavirus. the curfew will be in force from 8.30pm at night to 4.30am in the morning. it has also put in place new travel restrictions, as have belgium and denmark. now on bbc news — newsbeat goes on a road trip to meet
