welcome to bbc news, i'm mike embley. our top stories... a change in policy on yemen as the us calls for an end to the work. we get a rare access at any damage caused in six years of conflict. what used on that those last week's coup. the world health organization insists the astrazeneca vaccine is still a vital tool in the global fight against coronavirus, despite concerns in south africa about its efficacy. and the english photographer who kept finding his innocent images labelled a sexually overt by facebook.

hello to you and welcome to our viewers on pbs in america and around the globe. presidentjoe biden has called for an end to the war in yemen, which has killed around 100,000 people according to one un estimate. it's been six years since a saudi—led coalition intervened in the country's civil war, to restore an internationally recognised government to power. but houthi rebels, backed by iran, are fighting to regain control. the bbc�*s international correspondent 0rla guerin has had rare access to yemen. a warning, you may find some parts of her report distressing. aden, a city cradled by mountains in a country overshadowed by war. it's the seat of power of yemen's internationally recognised government, which is propped up

by saudi support. but when ministers flew in from exile in riyadh, this was the welcome. the first of three missiles slamming in. screaming the woman screaming in fear is a localjournalist, alia fouad. i saw fire. and i saw so many people running on the ground, kids, women injured, killed. for a moment, ithought about my family.

yemen's foreign minister, ahmed bin mubarak, saw the full horror from the plane, along with the rest of the newly—formed unity government. i was very optimistic. i hoped to return to the country, start, you know, the process. as the foreign minister, it was top of my agenda to start preparing for the peace process and, you know, dealing with all of these other challenges. we never thought that we're going to have such an attack. but in just 60 seconds, 21 people were killed, including aid workers and airport officials. the government blames iranian—backed houthi rebels who control most of yemen. they deny it. the news was broken on this tv channel by their reporter at the scene.

adeeb al—janani was killed on the spot, on one more dark day for yemen, leaving behind five young children. "he died, died, died," says his mother, who had begged him not to go. she was having so many plans... and in another home in aden, another room full of absence. she used to have one lovely smile. yasmine was one of the 18 people killed at the airport. she was yemen's deputy minister for public works. do you have any thoughts, any words, for the people

who would carry out an action like this? yeah, i have... it's not only our family that lost a really beloved person. it's around... i don't know, each and every house definitely have someone they lost. i'm sure whoeverjust did this thing, i am sure also that he has lost someone in his family. so i'm just saying, let's talk. can the conflict be stopped? it's deeply embedded here and it's playing out against a backdrop of regional rivalries. the new us president, joe biden, is pushing for peace. he may need to be ready for the long haul. 0rla guerin, bbc news, aden. protests against the military coup in myanmar have spread across the country for a third day.

largely peaceful so far, there have been some clashes between the security porters. —— security forces. the commander—in—chief of the military has spoken out for the first time on television — justifying his actions. the bbc�*s nyein chan aye reports from yangon. chanting sending a message to the generals. for a third day, anger has brought tens of thousands of people out onto the streets. worried about the future of the country, the people here say that their freedom has once again been taken away. this generation did not think they would have to do the same resistance against the military rule. young people hoped they would grow up in a very different myanmar, open to the world and its possibilities. but now they find themselves battling to restore democracy and end military rule, just like the generation before them.

but that fight won't be easy. their leader, aung san suu kyi, is still under house arrest. and today, the general who put her there spoke for the first time since taking power. justifying the coup, he said civilian leaders had failed to hold a proper election last november. across the city, red shirts hang outside homes in support of the protest movement. inside one apartment, this family say they have been protesting against military rule for three generations. for them, history has a way of repeating itself. 44—year—old thet thet aung spent four years in prison for protesting. translation: i feel really

bitter about this coup. - "so it happens again," i said in my heart. i can't sleep thinking that our new generation will suffer this again. some here arejoining protests for the first time. this student, who can't show his face for safety reasons, spent most of his adult life in this young democracy. so the thing i don't like about the military takeover is everything. i feel like we have no freedom. i feel like we have lost our freedom at home. as the protests build, the military is already starting to tighten the grip on the country. despite mass demonstrations in many cities for days, there is still no sign that the military will back down. nyein aye, bbc news, yangon.

let's ta ke let's take you live now to yangon. we're nowjoined by aung kyaw moe. he founded the center for social integrity, which promotes social and economic cohesion in myanmar. we are heading into what is likely to pay for their protest in myanmar, how do you expect this to go and what you expect to come? ._ this to go and what you expect to come?— to come? the third day of the rotest to come? the third day of the protest has — to come? the third day of the protest has been _ to come? the third day of the protest has been completed l to come? the third day of the . protest has been completed here very peacefully, but followed by that, there was quite a lot of different laws put in place by the military like article 144 has been released yesterday around eight o'clock in 18 different townships including some here in yangon. and the entrance to yangon here has been closed by heavy security forces, by the police so the plan to be demonstrating like yesterday, the day before yesterday, the day before yesterday and the other day

before yesterday is not there, but however, ifeel like before yesterday is not there, but however, i feel like there is a big moment in the peoplepower to be gathering in any that they could and this will continue. i will expect this will continue to be moving forward until the issue is resolved. i forward until the issue is resolved.— forward until the issue is resolved. forward untilthe issue is resolved. ~ ., ., resolved. i know you and your u-rou resolved. i know you and your grow) and _ resolved. i know you and your grow) and many _ resolved. i know you and your group and many are _ resolved. i know you and your group and many are in - resolved. i know you and your group and many are in favour| resolved. i know you and your i group and many are in favour of peaceful change, but we already seen water cannons used by the military and we know they have killed many many people in the past. do you think real change can come without more violence? there is no really granted that there will be no violence and military crackdown has injured many and killed many of the past when this kind of a protest has occurred in myanmar and around the world. and of

course the mai mai military has a different history compared to the other one. —— myanmar military i think the country has messed up with him in generations here and many young people are going on the street with all of the possible means they have, with all the capacity that they have within themselves to collectively put down the military and we expect the response from the military could be heavy, but however, i think the resistance by the people is also very high. what do ou people is also very high. what do you make _ people is also very high. what do you make of _ people is also very high. what do you make of the _ people is also very high. what do you make of the promises| people is also very high. what do you make of the promises of fresh elections? do you believe them? i fresh elections? do you believe them? ~ , , them? i think it is very difficult. _ them? i think it is very difficult. again, - them? i think it is very difficult. again, to - them? i think it is very difficult. again, to go l them? i think it is very - difficult. again, to go back to my previous point, it is really difficult to trust those who have been lying to us for generations and generations. so i think it is once again a different game that they want to play and as citizens of myanmar, i do not have trust on that. ., ' . ., . that. how effective a tactic for the military _ that. how effective a tactic for the military is - that. how effective a tactic for the military is cutting i that. how effective a tactic. for the military is cutting off of the internet? it is a big

myanmar. the world health organization insists the astrazeneca vaccine is still a vital tool in the global fight south africa. about its efficacy. the world health organization says it's too early to write off the astrazeneca vaccine, and that it still has an important role to play in the fight to control the coronavirus. that's after a disappointing day when a study in south africa found that the vaccine was not proving to be as effective as researchers had hoped against a new variant sweeping the country. astrazeneca hopes it will have an adapted vaccine ready by the autumn. the next phase of the pandemic could become a game of catch up between the variants and the vaccines. 0ur science editor david shukman has more. around the world, there is now a race between the virus and the vaccines, between the threat of new variants and efforts to stay ahead of them, and the outcome matters to us all. while a first wave of countries, including the uk, should see the majority of their populations vaccinated this year, others won't reach that stage till next year, and many will have to wait for the year after, or even longer. this is a global virus, it's a global pandemic. until we are all protected, then it could be that a variant in another country mutates,

so that the current vaccines are no longer effective, and that will come back, so even those people who are vaccinated, they are still going to be at risk with these future variants. the virus is changing all the time, and when it infects human cells, it takes over and gets them to make millions of copies, but they will not all be the same. each batch may have some random genetic mistakes, mutations that are usually unimportant, but a few might prove dangerous. so the first task is to track these changes, and that is done by studying the genetic code of the virus. since december 2019, when it was first confirmed in wuhan, scientists have monitored what effectively is a family tree, with hundreds of different branches. each of these lines represents one of many different variants that has emerged over the course of the past year. it is only by doing this genetic research that we can spot the variants that are worrying, in the uk,

brazil and south africa. half a million british coronavirus samples have gone through genetic screening so far. these machines are among those that have done most of the analysis. but few countries can work on this almost industrial scale, so there is a lot we don't know about how the virus is changing worldwide. there are thousands, millions of cases globally. there are undoubtedly other variants of covid that are spreading quickly that we are just blind to, and any one of those additional strains around the world could confer an advantage for the virus, allow it to re—infect people, even though they have been vaccinated, and that is what we want to protect against. one answer is to have a global screening operation. in west africa five years ago, mobile labs studied the ebola virus. something far larger is needed now, and alongside that, the faster the vaccines can be rolled out and adapted, as new variants emerge, the safer we will all be.

david shukman, bbc news. let's get some of the day's other news. a court in hong kong is expected to decide shortly whether to grant bail to the media tycoon, jimmy lai, in a landmark case. he's been charged with colluding with foreign forces under the controverisal security law imposed by beijing. he is the highest profile figure arrested under the law since it came into force last june. israel's prime minister has pleaded not guilty to charges of bribery, fraud and breach of trust. benjamin netanyahu was making his second appearance in court since his trial began in may last year. he was charged over allegations that he accepted improper gifts and sought to trade favours with media moguls in exchange for positive coverage. mr netanyahu has called the charges "fabricated and ludicrous". in a tit—for—tat move, germany, poland and sweden have expelled russian diplomats in response to russia's removal of their respective representatives over the weekend. all three countries, and the eu, deny claims that they participated in demonstrations supporting russia's jailed opposition

leader, alexei navalny. a popular, previously uncensored social media app called clubhouse appears to have been censored in china. users of the american audio—only app have been experiencing disruptions, with some speculating that it has been put under the same restrictions imposed by chinese authorities on other social media sites. the united arab emirates' historic first mission to mars will soon be arriving at the red planet. the hope probe launched from japan lastjuly and will study the planet's weather and climate but one of the most dangerous parts of its journey has to take place successfully first. our global science correspondent rebecca morelle has more. a first for the united arab emirates. this was the moment last summer when it sent its spacecraft to mars. now it's almost reached its destination, but the probe, called hope, has a critical manoeuvre ahead —

getting into orbit. it needs to approach mars at just the right speed and angle. if anything goes wrong, the entire mission will be lost. we don't really want to hit the planet, nor do we want to pass by the planet. we need to be very precise in how the operation happens. the hope mission will see more of mars than we've ever seen before. its spacecraft has an elliptical orbit, swinging in closer and then much further away. at its closest, its flight matches the rotation of mars, so it hovers over some key features like 0lympus mons, the biggest volcano in the solar system. at its furthest point, the planet spins beneath it, giving it a much wider view. this means it will see almost all of the planet from both close up and from far away. the spacecraft will study the atmosphere to solve a big mystery of how mars transformed from a planet with water, like earth, to the dry,

dusty world it is today. until now, the uae has only sent satellites into earth orbit. arriving at the red planet will be a huge leap. to know that there is a spacecraft that has gone from this region further than any man—made object has ever gone, that is hurtling towards a small pink dot that you also see in the sky, i can't describe the feeling or the thought process, but i never thought that this was possible. the spacecraft has one shot to get into orbit. if it succeeds, history will be made, firmly establishing the united arab emirates as a new space power. rebecca morelle, bbc news. now, at first glance that looks like a pretty innocuous picture of a cow behind me, but according to facebook that was considered to be a "sexually overt" image. the mistake was one of many which kept happening

some kind of way of filtering that stuff out if it does not meet policies, that is absolutely understandable. so mike is up and running for now and facebook are investigating the issue. as for how the england team is deemed an overtly sexual, or a cow for that matter, i will let your the algorithms do the maths. paul hawkins, bbc news. spirit not for people in north—west kandy, a polar vortex, courtiers bending in brought —— canada, temperatures as low as minus 48.9 celsius. cold enough to instantly freeze boiling water in that classic test. extreme cold weather warnings have been issued in the area for much of this week. there is much more for your own all the news anytime on any bbc website and also on twitter feeds. thank you so much for watching.

hello. very cold out there at the moment, with ice around and of course further snow flurries, particularly in eastern areas. the heaviest of those snow flurries as we go through tuesday, covered by a met office amber weather warning across parts of central scotland. travel, power, communication disruption possible, as those snow levels start to mount up. but it's notjust that, it's the extent of the chill this morning. may be as low as around —14, —15 through some parts of central scotland. all starting the day sub—zero. you can see where those snow showers line up through central areas of scotland. there will be others around northern and eastern parts of scotland, and we'll see little snow corridors again across parts of england and wales, just focusing some of those snow showers to give a further covering in some places. either side of it, we will see just that light flurry most of you saw through tuesday, but a better chance of some

sunshine in between. you saw the winds, another windy day across the board. in the thermometers, temperatures barely above freezing — it's going to feel much, much colder than that. and with some of the strongest of the winds to be found down toward south—west england and the channel islands, it's here where the coldest wind chill values will be found, as cold as —10 through —8 through the afternoon. also the chance of some sleet and snow very close to cornwall and the channel islands to end the day. that will gradually pull away as we go through the night and into wednesday. a subtle shift in wind direction means snow showers pushing through southern scotland into northern england in particular, and a few lines further south. another icy night, temperatures could get even colder, —15, —16. now, the big picture to start wednesday has low pressure out in the atlantic trying to get towards us, but high pressure is holding on. and with the isobars opening out a little bit, the good news is it's not going to be quite as windy on wednesday. those winds more north—easterly, so it will be parts of south—east scotland, north—east england, the focus of showers. a few down east anglia, the south—east too, but more

of you dry on wednesday, more of you see the sunshine. it's not going to do much to the temperatures, still struggling to get above freezing in some spots. another widespread, harsh frost, then, to take us into thursday. plenty of sunshine around for many, but increasing cloud into the west. signs of weather fronts trying to push in as the breeze picks up. signs of something milder trying to edge in as well, but do not underestimate the power of cold air across europe. it could hold off that charge of milder air from the west and could stay cold for many of us right the way through into next week. bye for now.

area 0ur t are a op stories: myanmar�*s military has addressed the nation for the first time since the coup last week. he tried to justify saying there would be fresh elections next year. the world health organization has warned againstjumping to conclusions against jumping to conclusions about againstjumping to conclusions about the efficacy of coronavirus vaccines despite south africa saying the astrazeneca vaccine is less effective against the strain sweeping the country. who experts say it is still an important tool. lawyers for donald trump have asked lawmakers to dismiss claims against him in his second trial, or insurrection for inciting his supporters to march on the capital. five people died in the capital that —— violence that followed.
