have been reimposed. meanwhile, thousands of lorry drivers spent christmas day stuck in their vehicles in kent in south—east england, waiting to be tested for coronavirus and to be cleared to continue their journey to france. another 800 military personnel have been sent to help with the testing, and to distribute food and water to those caught in the severe disruption around the port of dover. andy moore reports. yells. this lorry driver did not expect to spend christmas day stuck in a queue of traffic at dover. his frustration was obvious and shared by many others as they waited for the backlog to clear. some drivers have been stuck for days after france closed the border on sunday to stop the spread of a new strain of coronavirus. under police escort, groups of lorries were guided from their holding point at the disused manston airfield down to the port.

these drivers had tested negative and were cleared to go. horn blares. the transport secretary grant shapps said over 10,000 lateral flow tests had been carried out on drivers in kent and 2a were positive. more than 4,500 lorries have crossed the channel, but that leaves thousands still to make the journey. for some drivers, that means a christmas stuck behind a wire fence, instead of at home. tradition! whole people — whole family stay on table. eat. relax. music. no? i stay here. local people are helping out with hot food and sympathy. because we live in dover, we wanted to do something — even though it's just a little something — and just spread a little bit of christmas cheer and take some hot mince pies and sausage rolls to people who probably or maybe would like them. the cross—channel ferries have been sailing as soon as they have a full load of lorries. they're not usually as busy

as this on christmas day, but this is not a normal christmas day in dover. andy moore, bbc news. eu ambassadors have been given a briefing about the post—brexit trade deal reached with the uk, by the bloc‘s chief negotiator michel barnier. uk mps will vote on the deal in parliament next week, before the existing trade rules expire on the 31st of december. here's our political correspondent leila nathoo. glad tidings of greatjoy, because this is a deal. some light reading. the post—brexit deal agreed yesterday between britain and the eu runs to more than 1,200 pages. this morning, the man who negotiated it for the eu side, michel barnier, briefed ambassadors of eu member states on its detail. reporter: what is the

plan for today, then? mission accomplished! what's in that blue folder sets out how the eu and uk will trade and co—operate from the new year. to finally have something on paper is a success for both sides. the deal was done in the nick of time, with the uk already out of the eu and transition arrangements expiring within days. mps and peers will have until wednesday to digest the detail, before being called back to parliament for a debate. good evening. there are unlikely to be any hold—ups in westminster, though — labour is set to back it. we will certainly be better off with this deal and we have to make it work. no deal would have terrible consequences for our country, and the labour party could not enable that to happen. during the long months of negotiations, both sides seemed determined not to give ground. what's now on the table is a compromise, but those

who campaigned for brexit have broadly given the deal a thumbs up. if the contents are as described by the prime minister, then i think it is a very satisfactory outcome and actually, an extraordinarily good one, given the rather bum hand he had been dealt when he took over from theresa may. britain's new relationship with brussels is now more defined. eu ambassadors are weighing up how the future looks with the uk on the outside. the deal will need time to play out in practice but both sides will be relieved it was, against the odds, done. leila nathoo, bbc news. millions of americans are facing the loss of their pandemic—related unemployment benefits from boxing day, amid a political standoff over a $900 billion stimulus package. the coronavirus economic relief was agreed by both sides, but mr trump wants bigger one—off payments and a cut in foreign aid — he's refused to sign the measure into law unless it is amended.

claudia sahm is an economist, who previously worked with us treasury secretary janet yellen at the federal reserve. she explained the consequences if the package is not approved. the stress will continue to grow. this has been a hardship and an uncertainty that millions of americans have dealt with for months now, as congress has tried to get a relief package negotiated and very specifically, the last of the jobless benefits will go out tomorrow to individuals who have been on unemployment for many weeks already, and for those who had eligibility because of the cares act, because of the earlier relief package. so those two groups, tomorrow is the last day. and the president absolutely has to sign it to get those back on track and of all of the rest that's in the relief package.

that brings me to my next question. there appears to be a lot of confusion over who supports what. can you help explain the difference between this covid—relief bill and the regular government funding which it is of course a part of? i think the thing to keep in mind is that the two sides had come together. the democrats and the republicans passed the relief package and the budget, which happens every year — there's a big budget — they passed both of them and it was looking like smooth sailing to go to the president for his signature. and that all blew up tuesday night so it really is disarray and even those of us who follow very closely what is going on in washington, who knows? right, they'll be back at it on monday but honestly, it is just the hardship and the uncertainty that they're inflicting on millions and millions of americans is just mind blowing — it's christmas. and, claudia, back at it on monday but an easy solution would be for the president to sign off on this bill. what do you think he will do? well, i hope he does the right thing and he signs off.

i will affirm that this bill, the relief package is not perfect, right? one of the things the president is asking is for bigger cheques to go out to families. i am all for bigger and better but the perfect cannot be the enemy of the good right now. this money has got to get out. so it is unfortunate that we are still niggling over details when people are waiting for this money. so i hope this comes together but this has been a very, very frustrating several weeks. claudia sahm there. a court in st petersburg has jailed a prominent russian historian, after he was found guilty of murdering and dismembering his young lover. 0leg sokolov was sentenced to 12.5 years for the killing of anastasia yeshchenko. he was found drunk in a river in november last year — with her severed arms in his backpack. the bbc‘s tim allman reports. a grim and grizzly tale reaching its conclusion in a courthouse

in saint petersburg. 0leg sokolov, a once—respected historian, now convicted of murder. also present, the parents of the young woman he killed, there to witness some justice at last. translation: this person is used to avoiding responsibility. he has high—ranking friends and connections. i'm very glad that the court heard us and did not allow the defence to discredit the murdered girl. a postgraduate student who had lived with sokolov for more than three years. ——the murdered girl was anastasia yeshchenko, a postgraduate student who had lived with sokolov for more than three years. in november last year, he claimed they had a blazing row at the flat they shared, she attacked him with a knife. he then shot her four times with a shotgun, before dismembering her body. you can see him here on cctv cameras dumping objects into the river.

those objects were believed to be the remains of anastasia yeshchenko. 0leg sokolov was a renowned authority on the life and legacy of napoleon bonaparte, even dressing up to take part in battle re—enactments. but women's rights activists say this case shows the indifference towards harassment and domestic violence that often takes place in russia. translation: this model of behaviour towards women, the violence against women, is often unheard by our law enforcement bodies. if they had reacted earlier, i'm sure that the death of anastasia yeshchenko would have been impossible. 0leg sokolov‘s sentence has been criticised. prosecutors wanted him to serve 15 years behind bars but, as the lawyer for anastasia yeshchenko's parents put it, no jail term will bring back their daughter. tim allman, bbc news.

stay with us on bbc news — still to come: the power of setting a good example — why some world leaders are determined to have their vaccine jab in public. the world of music has been paying tribute to george michael, who's died from suspected heart failure at the age of 53. he sold well over 100 million albums in a career spanning more than three decades. the united states' troops have been trying to overthrow the dictatorship of general manuel noriega. the pentagon says it's failed in its principle objective to capture noriega and take him to the united states to face drugs charges. the hammer and sickle was hastily taken away. in its place, the russian flag was hoisted over what is now no longer the soviet union, but the commonwealth of independent states. day broke slowly over lockerbie, over the cockpit of pan am's maid of the seas, nosedown in the soft earth. you could see what happens

when a plane eight storeys high, a football pitch wide, falls from 30,000 feet. christmas has returned to albania after a communist ban lasting more than 20 years. thousands went to midnight mass in the town of shkoder, where there were anti—communist riots ten days ago. this is bbc world news. the main story this hour: possible human remains are found near the debris of a large explosion in the centre of the us city of nashville. more now on that story. joey degraw owns a bar in downtown nashville, close to the explosion site. he gave us his account to what happened in the early hours of christmas day. there was a bomb that went off, it turns out, and very close to, half a block from our place called nashville underground, right on broadway, we're the largest bar—restaura nt and onlyjust a half a block

so it was pretty devastating. nashville doesn't see stuff like this much. can you tell us a little bit about what you felt or what you heard? yeah, i can tell you a lot about it. my brother, gavin, and i live on the same floor in a high—rise building just a couple of blocks away from the bar — it literally knocked us out of bed. i thought it was an earthquake. and we panicked. i put my pants on, ran out in the hallway and tried to figure out what was going on, and it turns out it was some kind of attack. it must have come as a shock on christmas day. tell us a little bit about what the scene is like at the moment? i think everybody in the town is a bit dishevelled, including the authorities. nashville is not used to stuff like this and i am not so sure that they can figure it out

as quickly as it needs to be figure it out. i just don't know. it is not something we see here much. joey, tell us a little bit about what that area is usually like. you say it's a shock for nashville to experience an explosion like this, especially on christmas day. tell us more about what the neighbourhood is like? well, where our bar is, more drinks sales per square foot than anywhere in the whole country, on the five blocks between 5th avenue and 1st avenue. it's a huge party town but there is a lot of residential high—rises and such around it as well. so there's a lot of tourism and there's a lot of residents that kind of live in town that thank god were sleeping when this thing happened, it seems for the most part. although i understand there are some casualties, u nfortu nately.

air canada has revealed that one of its boeing 737 max planes was forced to divert earlier this week when it experienced engine problems shortly after take—off. the plane, with three crew members on board, was flying from the us state of arizona to montreal at the time. air canada said the pilot shut down one of the engines before landing in tucson. the 737 max was grounded worldwide last year following two crashes, linked to cockpit software, that killed nearly 350 people. it was cleared to fly again in november. israel has targeted a number of sites in gaza after several rockets were fired from the strip. the israeli military said it had hit a rocket manufacturing site, a military post and some underground infrastructure. on friday, israel's anti—missile iron dome system intercepted two rockets fired from the territory. the military said it would hold the hamas movement responsible

for any attacks emanating from gaza. as inoculation begins around the world, politicians and celebrities have been filmed and photographed receiving the coronavirus vaccine. us president—electjoe biden and israeli prime minister benjamin netanyahu broadcast their experiences, and the latest is saudi arabia's crown prince mohammed bin salman, who was given a coronavirus vaccination live on television. the kingdom is beginning a nationwide immunisation programme and the health ministry says more than half a million people have registered to take the vaccine so far. dr noel brewer, professor of health behaviour at the university of north carolina, told me more about the influence of high profile figures on vaccine uptake.

it certainly doesn't hurt to have famous people getting the vaccine. it communicates a few different things. most importantly it indicates a social norm, that this is simply what we do. this is what famous people do, and this is what regular people can do as well. the message communicated by movie stars doing it as opposed to a politician may be slightly different. someone who is at the top of government getting vaccinated communicates that the system of vaccination is safe, the vaccine itself is effective and it's safe. but the system is working well. when a celebrity does it, it brings along their brand, their cache as well and makes the vaccination seem desirable. something that might me fashionable, modish or at least something you would want to do to be a little like them. and do you think there's a perfect example, someone who might be really effective in doing this? i think the perfect person is going to vary quite a bit. in the united states we have dramatic disparities in who is getting and dying from covid.

so african—americans are much more likely — they're two or three times, depending on what data you look at — even higher in some data — so they are many times more likely to get and die from covid, so having spokespeople or having people getting the vaccine who are black is very important. who those people are is something you should probably ask the people in the community themselves about. so names that come to mind for me — barack 0bama, famous movie stars and so on are people on my mind, but it's best to talk to people in the community themselves and ask who do you trust? and those are the people you want to have on television getting vaccinated. and noel, just one final thought. do you think governments around the world are doing enough to increase positive messaging on this vaccine? i don't think we are doing the right things yet. there is a lot that's in place and sort of being developed. there's been a big scramble to just get the vaccine ready and to get it out the door but the next — or the first stage was simply the process of getting the vaccine available. the next stage is going to be this messaging stage where we're talking to the

public and having campaigns. but there is a third stage which is actual behaviour change interventions and that is the thing i am looking forward to seeing, to hear the scientists at the table and helping with, and that will be where we can change uptake globally. a boston doctor developed a severe allergic reaction after receiving moderna's coronavirus vaccine on thursday. the boston medical centre doctor, who has a severe shellfish allergy, had a reaction almost immediately but was able to self—administer his epipen. he was taken to the emergency department for treatment and observation before being discharged. it is the first severe reaction publicly linked to moderna's vaccine, which is in its first week of a nationwide rollout in the us. an australian expeditioner who fell sick in antarctica has been evacuated to hobart after an incredible multi—national effort involving china, australia, and the united states. the rescue mission

took five days and spanned thousands of kilometres. it involved ships, helicopters, and planes. the australian national was at the davis research station in east antarctica when the operation to move him began. senior officials have praised the international co—operation that occurred despite freezing weather conditions. it weather conditions. really reflects the very best it really reflects the very best of that multinational activity that occurs in antarctica. it really is the united nations of antarctica, bringing together nations to support each other to deliver operations. we have been doing this for a long time, but this particular evacuation was the very best spirit of that multinational cooperation. first the beatles did it, then the spice girls, but now youtubers known as ladbaby have become the third act in uk history to get three consecutive christmas number ones — with a song about sausage

just clearing the south—east of england, and then the skies clear. we find ourselves in the centre of the low pressure, and here, the weather will be quite changeable. there will be sunny spells, showers, some of them will be wintry, and it will be a good deal colder, temperatures 3—6 degrees, and then cold enough on monday for the potential of some snow there, even across southern parts of the uk. we're keeping a very close eye on this weather here developing in the south come monday. bye— bye.
