this is bbc news. these are the latest headlines in the uk and around the world. us presidentjoe biden warns russian leader vladamir putin that he'll respond with "severe economic sanctions" if ukraine is invaded. the armed forces minister warns the uk will not be able to fly british nationals out of ukraine if russia invades — and says russia's in a position where it could attack "at no notice". this risks escalating in a way that is really quite terrifying. this is the largest concentration of troops on the european continent in 70 years. in paris, french police fire tear gas at demonstrators — it's after a convoy carrying protesters against coronavirus restrictions made it into the capital. borisjohnson receives a legal questionnaire from police investigating lockdown parties

at downing street and whitehall. doctors say thousands more lives could be saved by paying attention to earlier symptoms of heart attacks. a new campaign to spot the signs is launched by nhs england. tense scenes in the final of the club world cup, with chelsea leading palmeiras 2—1 at the end of extra time. hello and welcome, if you're watching in the uk or around the world. a day of high—stakes international diplomacy — over a possible war in ukraine has culminated — in direct talks between president biden and his russian counterpart, vladimir putin. the white house said mr biden reiterated that a further russian

invasion of ukraine would produce widespread human suffering and diminish russia's standing. mr biden said he was committed to diplomacy but also warned of the "severe costs" of any russian military action. mr putin has accused the west of stoking tensions. more than a dozen nations, including the uk, have urged their citizens to get out of the country. our correspondent paul adams has been talking to some of those affected. do you want to go to spain? how best to leave? stuart mackenzie is looking for flights with his sons, robert and stuart. after 28 years of life here, he can't quite believe it. this is just crazy, just crazy. it's a peaceful country and, in this day and age, and you're talking about tanks and bombs coming in, this is crazy. i don't understand, and we are in europe. there is a lot to think about — what to do with start�*s elderly mother—in—law, his brother's family also here, and his 20 local employees.

if there are flights available for the family, then that is a good option for us, that gets us out within hours. if that is not the case, then plan b is taking the car and trying to get to the border — and praying that we are not too late. at the british embassy, signs of urgency and departure, no one here willing to talk. the foreign office says it is not in a position to help british citizens with their plans. nearby, a march of defiance in the face of a gathering storm, a rare display of public feeling at a time when russia is menacing their borders, staff are leaving embassies and foreigners are being told to get out. i have to analyse all the information which we have. touring the south, ukraine's president seemed frustrated by apocalyptic warnings coming from washington. and the truth is that we have different information and now the best friend for enemies,

the panic in our country. and all this information helps only for panic, it doesn't help us. russia's war games in belarus are now under way. this, american officials warn, is how an assault on ukraine could begin. moscow still says it has no plans to invade. joe biden and vladimir putin spent an hour on the phone tonight, no word yet on what was said. mr biden told the russian leader if he launches a further invasion of ukraine, the west and its allies will impose swift and decisive sanctions. pauladams, bbc news, kyiv. our correspondent fergal keane is in kyiv and he's been speaking to ukrainians who have been out in the city protesting, to get their thoughts on the situation. the event was organised by a right—wing nationalist group, along with an anti—zelensky group, but there were people from all political spectrums. this is the first real manifestation we've had of public feeling

since the anxiety of a possible russian invasion has increased over the last 2a hours. and what you can see around me here is people of all ages and seemingly from all sides, all shades of political opinion coming out onto the streets here in a very important place, in terms of ukraine's progress to democracy, the maidan. people saying they will resist any russian intervention. why have you come here? the main reason is to show the unity of the people before the threat of russian occupation. this is the main reason that we are all united. because different people, different political orientations, different political parties — but today, we are all together because we have a threat of russian invasion.

and that's why we are showing to each other and the whole world that we are ready to fight, we are ready to defend our motherland, our country. and that's the reason, actually. yeah, i'm here because i want to show that i'm not terrified by the threats. we are ready to oppose putin, or anyone who wants to invade our country even more, because you know that some regions already don't belong to us. so we are ready to fight with any means that we have. i didn't go into some training, but i will fight with anything i will have in my hands, and i will do anything my country asks me to do. medicine, shooting, anything. i love my country, i'm not afraid. this is quite a strong moment for you. we ukrainians are very strong.

so i don't advise anyone invade our country. let's get reaction to that phone call between president biden and mr putin with our correspondent in los angeles, david willis. hi david, the first phone call between the two presidents since december — is there any sense coming from the white house that diplomacy is in any way working? hat from the white house that diplomacy is in any way working?— from the white house that diplomacy is in any way working? not much sign of that, it must _ is in any way working? not much sign of that, it must be _ is in any way working? not much sign of that, it must be sad. _ is in any way working? not much sign of that, it must be sad. the - is in any way working? not much sign of that, it must be sad. the two - of that, it must be sad. the two leaders, as you say, spoke for more than an hour today, and a readout of that conversation from the white house raised perhaps more questions thanit house raised perhaps more questions than it answered. it certainly doesn't refer to any areas of agreement between the two leaders. it said that president biden reiterated what it called the western allies's willingness to respond to any invasion and impose swift and severe costs on russia. but it gives no indication of what

president putin had to say in response to that. now a little later, a state department official in the background told reporters that there was no fundamental change, as he saw it, in the dynamic between these two nations, and that military action on russia's part now was a distinct possibility. the united states, along with many other countries, has moved diplomats out of the ukrainian capital, kf, the us making the point yesterday that it couldn't mount some sort of military operation to safeguard them should there be an invasion —— kf. the point is really being made by officials, as well, that really knows what'll happen over the next few days is vladimir putin — and the us is quite plain about the fact that it has no insight whatsoever into his thinking. "we

don't have full visibility on his decision—making," was how one official put it today. decision-making,�* was how one official put it today.— official put it today. david, president _ official put it today. david, president biden _ official put it today. david, president biden warned i official put it today. david, - president biden warned president putin that in the event of military action, there would be a swift response. what could that response look like from the us?— look like from the us? well, it could look _ look like from the us? well, it could look in _ look like from the us? well, it could look in the _ look like from the us? well, it could look in the form - look like from the us? well, it could look in the form of- look like from the us? well, it - could look in the form of sanctions imposed on military, technological, and all sorts of different areas, impeding russia's ability to operate in the financial system, global financial system. swift and severe economic costs, the west is talking about imposing on russia, but it does appear anyway that the russians, despite pursuing diplomatic channels, continuing to talk in this conversation between putin and biden this morning was one of a number of conversations that also involved the defence secretaries of both countries, and

of course, the us secretary of state and his russian counterpart. but there appears to be no breakthrough so far. ., ~ i., canadian police have started clearing protesters blocking a bridge linking canada and the us — more than 12 hours after a court ordered an end to the blockade. the demonstrators are protesting about covid restrictions and vaccination rules for essential workers. the blockade has affected trade and supply chains. the motor industry says it's been losing millions of dollars a day. michelle maluske is a reporting for canadian media at the ambassador bridge — she gave us this update. at 8am this morning, police came onto the scene from three different areas. and what they did was walk in behind the protesters and split the blockade in two. they went to the right and spoke with the owners of the vehicles that were parked on the foot

of the ambassador bridge to the right and asked them to leave, which they did willingly. you're watching bbc news, it's time to leave our viewers from bbc world news, thanks for watching. french police have fired tear gas on demonstrators protesting against covid restrictions in the capital paris. there were scuffles between police and protesters near the champs elysees. earlier, police stopped hundreds of cars that arrived in convoys from across france to take part in protests. the demonstrators say they've been inspired by the blockade by truckers on the us—canada border. similar protests have been taking place in countries across europe, including austria, the netherlands, and belgium. our paris correspondent hugh schofield has more. it's much improved. there are still skirmishes of a very limited nature taking place at the top end of the champs—elysees. essentially what happened was that some of these vehicles that were driven by protesters did get through the various roadblocks and checkpoints, up to the champs—elysees earlier

in the afternoon. there they stopped and got out of their cars, and blocked the traffic. and that formed a, kind of, hub for protesters to come on foot and engage with the police who were out in force. that went on for 2—3 hours — scenes that were very reminiscent of the yellow vest protests of three years ago, if you remember when we saw again, protesters out in force. here, there was a lot of tear gas being fired to break up little groups of protesters who were forming, but nothing terribly serious. but still a certain degree of tension. and then gradually, the police were able to bring in special vehicles to tow away — tow trucks to take away the vehicles that had been accumulating at the top of the champs—elysees. it's more or less over now, but there's still lots of people and plenty of police out there. i don't think there's any more tear gas being fired. and hugh, are the reasons for the protests the same

as the ones in canada — namely against covid restrictions — or is it more than that? well, it is both — it's that and more than that. there's no doubt that many of the protesters feel inspired by what's happening in ottawa, on the us border there. they feel that here, as there, there are restrictions on their liberties, because of laws about covid passports and so on, and vaccination that the government has imposed. but, in my mind and most people's mind, there is a clear link between this and the yellow vest movement. this is a kind of aftershock of the yellow vest movement, a lot of the same people are out there today with the same visceral anti—macron feeling, and the same calls, as well, for caps on fuel price rises and so on. so there's the bigger issue of covid, but also very french issues of anti—macronism and price rises.

and are these demonstrations limited to paris, or do they go into the rest of the country? this is paris, this covid freedom convoy, so—called protests started off in towns all over france. but what the people have done is drive up to paris, and today was to be the big day where they gathered in paris. i think they envisaged something much more effective than this. we've seen some quite dramatic pictures at the champs—elysees — but in reality, the impact has been very small, life has gone on here without any real change at all today, except for a couple of hours. so they haven't had any real great impact on daily life — they've made the news today, and i think tomorrow, most of them will go home, and some will continue to brussels. downing street says borisjohnson will "respond as required" after he received a police questionnaire yesterday about events

he attended during lockdown. the metropolitan police says the questionnaires — which are the written equivalent of police interviews under caution — are being sent to more than 50 people who attended downing street parties that may have broken covid laws. our political correspondent jonathan blake explained what will happen next. well, the prime minister is now required, as the police put it, to provide an account an explanation of his participation in an event or events. the questionnaire has formal legal status, the police say, and it must be answered truthfully. we don't know exactly which events the prime minister's being asked about, but among those we do know he attended is the drinks in the downing street garden in may during the first lockdown of the pandemic, which she has previously said he believed was a work event. now the police have stressed that those contacted in this way won't necessarily end up with a fine, fixed penalty notice — but of course, they could do on the basis of their answers and the hundreds of pieces of evidence that the mets are trolling through as part of this investigation.

so what next? well, the prime minister has seven days to respond. during that time, he'll attempt to show that he's getting on with the job — at best, this is a distraction, though, at worst a decision looming that could seal the prime minister's fate. the headlines on bbc news... us presidentjoe biden warns russian leader vladamir putin that he'll respond with �*severe economic sanctions' if ukraine is invaded. in paris, french police fire tear gas at demonstrators — it's after a convoy carrying protesters against coronavirus restrictions made it into the capital. borisjohnson receives a legal questionnaire from police investigating lockdown parties at downing street and whitehall. protests have been held in several towns and cities around the uk, to highlight the impact of the cost of living crisis on workers and their families. the austerity campaign group, the people's assembly

co—ordinated the demonstrations, supported by trades unions. inflation, the measure of how quickly prices are rising, is at a 30—year high, amid steep increases in the cost of fuel, heating and food. yet official inflation figures look at a wide range of goods, notjust food, so can often mask some steep rises seen at the supermarket tills, especially on everyday items. new data for the bbc suggests that a basket of mid—range groceries has gone up in price by 8% injust one year. our business correspondent emma simpson reports. charlotte jessops, a money—saving blogger. she hosts a monthly zoom session, passing on tips. thank you for coming. we're going to be talking about the rising costs of food. my shopping bill for me and my partner has gone up at least £20 a week. the bread, even the, you know, the lower end brand has- gone up like 20, 30p. everyone's shopping basket is different. we looked at some popular items. take a pack of spaghetti.

it's gone up by an average of 41% since last year. a tin of tomatoes has jumped 21%. and a jar of strawberry jam up by 20%. in the cheapest range, the prices were also up, but not by as much. this is a once—in—a—generation moment forfood price inflation in this country. this is just the start. it's going to go on for two, two—and—a—half years, probably, as various costs and problems filter through into the system and are accommodated. here in the aisles, the battleground is all about price. the supermarkets are grappling with how much of their costs to pass on, but if they put their prices up too much, shoppers will vote with their feet. this business is hoping to nab some of them. poundland's biggest store opening in nottingham today. feels like a supermarket. are you after more of the weekly shop? yeah, absolutely we are. and that's why we're providing all these new categories,

fresh foods, produce. but costs are rising across his supply chain too. high, single—figure inflation is what we're facing. that doesn't mean that our shoppers have to face that as well. so, you know, i'm not a magician, not paul daniels. i can't magic all of this stuff away, but what i can do is work as hard as i can on behalf of shoppers to make sure that we mitigate as much as we can to protect them. that may be, but overall food prices are moving in one direction, and that's up. emma simpson, bbc news, nottingham. the nhs has launched a new campaign to encourage people to dial 999 if they suspect they're in the early stages of a heart attack. doctors want to improve awareness of common initial symptoms such as sweating, feeling dizzy and tightness in the chest. jon donnison reports. a new tv ad urging people to look out for the early signs of a heart attack. a feeling of unease. but a poll of 2,000 people carried out for the launch of this nhs campaign found that fewer than half

those asked knew to dial 999 if they or a loved one were experiencing some of the more vague symptoms, such as sweating, light—headedness or feeling weak and uneasy. if people are suffering a heart attack, the earlier they call for help, the better. there is a phrase amongst cardiologists which is "time is muscle". the longer you leave things, the more likely people are to suffer from a bigger heart attack which is likely to have a greater impact in their life going forward. so the sooner they call for help, the better. and nhs figures bear that out. each year in england, there are more than 80,000 hospital admissions for heart attacks. the overall survival rate is around seven out of ten people, but that rises to nine out of ten people for those who seek early hospital treatment. the doctors behind this new campaign say that a heart attack is always a medical emergency and that it is never too early

to call 999 and seek advice. john donnison, bbc news. two men and a boy have been charged with murder after a 21—year—old man was stabbed to death in eltham, in south—east london. a family friend said ba rtosz wyrzykowski was attacked in lionel road, eltham on tuesday afternoon while out getting milk with his girlfriend. the met police said two men, aged 21 and i9, and a 16—year—old boy will appear at bromley magistrates' court later. a 21—year—old woman and 17—year—old girl have also been arrested on suspicion of assisting an offender. they have been bailed pending further inquiries. a boat sent by the government of mauritius has arrived in the disputed chagos archipelago in the indian ocean. the united nations' highest court has ruled that britain's occupation of the islands is illegal, but britain has refused to hand control to mauritius. those on board include a number of islanders who were forcibly evicted to make way for a us military base. mauritian officials are expected

to raise the nationalflag on at least two of the islands. our correspondent andrew harding was on board and sent this update. these are the five chagosians who have come back to this island that they were kicked off, essentially, by britain 50 years ago. they wept, they dropped to their knees, they kissed the sand on the beach behind me here. since then, they've gone to inspect some of the ruins of their old homes on this extraordinary island that really almost no—one has been to for these past decades. strict control from britain about who could actually get there until mauritius made this very bold move to send its own boats without securing permission from britain, simply going ahead and coming here. and if you can see behind me, the men, the mauritian officials, they're busy planting a concrete base for a flagpole, and then they're going to raise the mauritian flag over this island, as on a couple of other reefs and islands in the coming days. a really very defiant,

bold move by mauritius, which says, "look, international law is on our side. only five other countries in the whole world now support britain's claim to the chagos islands. "it is time," the officials here are saying, "for britain to accept internationaljustice and hand the islands back to mauritius, back to the chagosians." certainly those on mauritius desperate to come back and stay here. chagosians in britain no more divided — many of them still supporting britain and its claim to the islands. a disability rights campaigner has posted a video on social media, showing a commuter harassing him and his guide dog on a london underground escalator. this video of the interaction shared by dr amit patel — who is blind —

has now been viewed online more than a million times and prompted an outpouring of support. for those who use an escalator probably don't realise just how bouncy they are, how much noise they make, what the environment around them — as a blind person, that's why i have to keep myself safe, it's listening to all these sounds. so holding onto an escalator and her harness, and then having someone tried to walk over her, walk around her, or even shout at me — it's just a difficult situation because i don't know how far that'll escalate. because she's trained specifically to get to the escalator, to stop, and wait for the command "forward" — socialjump on, so that way she doesn't catch her pause, and for me to hold onto the rail. and she will stay there until it starts to level out, she'll walk, and thenjump off the end. and you are necessarily occupying more space than somebody who would be standing on their own? absolutely — she's always on my left—hand side. so we will take up the left—hand side of the escalator, which means you can't walk up or down it.

but the majority of people understand, you know, sometimes people shout from the top, "why are you moving forward?" —— why aren't you moving forward? and there'll be a little trickle going up saying, "there's a guide dog, there is a guide dog." and by the time you get to the bottom or top, someone will come up and say, "i'm so sorry, i didn't see your dog" — which is absolutely fine, and 99% of the time, the journeys are great. but those i% where it puts you in danger — and it's not so much my fear, it's my fear for her, if she catches her paws or it gets to a stage where she doesn't want to get on an escalator, it makes life really difficult. generations of children will be familiar with beatrix potter's tales of peter rabbit and jemima puddleduck — but as well as an author and artist, she was a scientist and conservationist. and she grew up not in the countryside, but in central london not far from the v&a museum — where there's now a new exhibition celebrating her work. frankie mccamley has been to take a look. once upona

taken over by developers for holiday homes or anything. before that, miss potter lived in south kensington. she loved collecting shells, rocks and fossils, studying them under the microscope. and, as a budding illustrator, she visited this museum. it's appropriate that it's at the v&a, because her archive is stored here at the v&a. but also, because she lived near the museum, and she visited as a child and as an adult, she created drawings, plaster casts from our collections, and some of our objects, as you will see in this exhibition, actually appear in her stories. including this waistcoat she sketched as a child here. it later appeared in her story the tailor of gloucester. the exhibition is the largest in the world, including personal letters and family photographs. there is also some fun to be had if you want to bring miss tiggy—winkle to life. frankie mccamley, bbc news.

areas of the uk. but out towards the southwest, this is the front that's approaching, and that will sweep into many western and southwestern areas through the early hours of sunday morning. so quite a wet start, particularly for wales — but in northern and eastern scotland, it should actually be a dry and bright start to sunday, but a little on the nippy side, maybe in the coldest spots, temperatures will be close to freezing, but elsewhere it will be a relatively mild night. so look at all this rain moving across the country during the course of sunday, it rained pretty much everywhere at one point or another — all but the north of scotland and the northern isles, maybe a few showers here, but that's pretty much it. so some sunshine for stornoway, and elsewhere it'll quite a grey day, and that rain in the south will probably last all through sunday and into the early hours of monday.
