welcome to bbc news, i'm mike embley. our top stories: one of the world's most dangerous places, especially if you're a child — more than a50 killed or wounded in yemen's �*city of snipers.�* we've a special report. you can go here from building to building here, family to family and hear more stories of children who have been deliberately targeted by snipers. myanmar�*s military crackdown. clashes with protesters, tanks on the streets, and harsh new punishments for those who challenge the coup leaders. emergency vaccine approval to help distribute the covid jab to poorer countries through the global programme known as covax.

americans hit by a chill as southern stays ahead by an unprecedented amount of snow and ice. welcome to our viewers on pbs in america and around the globe. yemen is one of the most dangerous places on the planet — its population suffering from a civil war that's lasted for six years, but the city of taiz is one of the most dangerous places to be a child. human rights workers say more than a50 children have been killed or wounded by houthi rebel sniperfire. the houthis deny it. taiz, in yemen's south—west, is home to one of the longest—running battles of the conflict. it's under virtual siege, divided between yemeni government forces, backed by a saudi—led coalition, and the iranian—backed houthis, who still control most of the population. our international correspondent orla guerin, cameraman

goktai koraltan and producer claire read sent this report from the so—called �*city of snipers�*. a warning — some of you may find the report distressing. in taiz, city of snipers, a family on the front line. ruwaydah saleh is eight years old. her big brother amri is ten. she probably owes him her life. here she lay last august after she was shot in the head. who took aim and pulled the trigger, herfamily have no doubt — a houthi sniper. it was amri who dragged her to safety.

ruwaydah arrived in hospital unconscious and had to have brain surgery. we reported on her story then, but couldn�*t reach her. now we have. she�*s still trapped in a city at war, and it�*s taking its toll, says herfather, saleh bin saleh.

in front of the family�*s home, right where ruwaydah was shot, kids just want to be kids. her attack caused outrage. since then, snipers have left the children alone on this street. under armed escort, we travelled to another front line area. they say houthi snipers have killed or injured more than a50 children in taiz. houthi officials say allegations of targeting children are completely false and come from their opponents. the makeshift barricades are to block the snipers�* line of sight. well, we have to move carefully here and take cover in these

front line districts. nowhere is safe and no—one is spared — especially, you can go from building to building here, from family to family, and hear more stories of children that have been deliberately targeted by snipers. one father wanted to tell us his story, so we followed him to his home. he runs this risk every day. so do his children. this photo of ten—year—old saber was taken last april. days later, he was dead. abdu tells me saber was shot out of a tree after climbing to pick fruit. the bullet passed through his body. saber�*s younger brother

mohammed was there and saw him die. he got shot in the stomach. the seven—year—old made it home and hid under a blanket, too scared to tell their mother they had climbed the tree. while mohammed survived, he�*s deeply traumatised. his mother says when he�*s not happy, he tells her, "i�*ll go to the sniper so he can shoot me again." across yemen, the young are at risk from all sides, and death often comes from the skies. air strikes by the saudi—led coalition, which supports the yemeni government and is backed by the uk,

kill many children. human rights workers here in taiz say the difference is, houthi snipers are systematically trying to kill them. back in ruwaydah�*s neighbourhood, a young boy plays dead. hard to watch. too often here, it�*s not a game. orla guerin, bbc news, taiz. and there�*s further concern for civilians in yemen, as houthi fighters step up their attacks around the city of maribthe nothern city�*s been a refuge for hundreds of thousands of displaced people who have been sheltering in or around it, but rebels have launched a fresh offensive. the un�*s humanitarian chief, mark lowcock, said an assault on marib itself could have unimaginable consequences. the leader of the coup in myanmar, general min aung hlaing, has said he will try to handle

the mass protests against the overthrow softly, although he didn�*t clarify specifically what this would mean. this comes after threats that protesters could face up to 20 years in jail if they obstruct the armed forces, or long sentences if they incite hatred towards the coup leaders. here�*s our south east asia correspondentjonathan head. gunfire. even for a country shocked at being back under military rule, it has been a stressful 2a hours. rumours of a full—scale army operation were strong, and here in myitkyina, repeated bursts of gunfire from the security forces made people think it was already happening. most of the shots, though, were fired into the air. then, an eight—hour, nationwide internet blackout. for what purpose, we still aren�*t clear. this morning, the military was making itself visible in yangon and other cities.

that didn�*t stop people from protesting again over their power grab, as they have for the past ten days. if anything, the soldiers provoked people to speak out even more over seeing their democracy crashed by the generals. this armoured vehicle found itself surrounded by hostile traffic, the drivers honking their anger. and here at the headquarters of the party led by aung san suu kyi, more anger. "release our leaders," they shouted at the police surrounding the building. they haven�*t forgotten that they re—elected her by a landslidejust three months ago. she�*s still in military custody, her detention extended today for who knows how long. the military�*s plans from now are hard to guess. the soldiers, though, are an ominous sign.

these are combat units used to fight armed insurgents on myanmar�*s borders, and in previous unrest to shoot protesters. and they�*re back on the streets again. jonathan head, bbc news. the world health organization has given emergency approval to use astrazeneca covid—i9 vaccines produced in india and south korea. the decision will help distribute the vaccine to poorer countries through the global programme known as covax. these jabs will make up most of the initial 330 million doses of covax�*s first rollout, which begins at the end of the month. we now have all the pieces in place for the rapid distribution of vaccines. but we still need to scale up production. and we continue to call for vaccine developers to submit their dossiers to the who for review at the same time, as they

submit them to regulators in high—income countries. the new head of the world trade organization has told the bbc that when it comes to vaccines, protectionism is not the answer to ending the pandemic. in one of her first interviews since she got one of the top jobs in global trade, nigeria�*s doctor ngozi okonjo iweala told our correspondent nancy kacungira her organisation could help accelerate vaccine rollouts. protectionism, with respect to vaccines, which we call "vaccine nationalism", is something that i don�*t think really works. because the nature of the pandemic and the mutation of its many variants, makes it such that no one country can feel safe until every country has taken precautions to vaccinate its population. so, with respect to that, the wto can do two things, number one: there�*s some wto rules that can be looked at to see how can you flexibly allow countries to manufacture more vaccines?

developed countries feel that this might impinge on intellectual property. and i feel that within wto rules we can find what i call a "third way", in which we can license manufacturing to countries so that you can have adequate supplies, while still making sure that intellectual property issues are taken care of. and it�*s happening right now. ethics expert dr kyle ferguson. he is the co—author of the essay �*love thy neighbour? allocating vaccines in a world of competing obligations�* in the bmj. good to talk to you. just from a new reader point of view, could you explain vaccine nationalism?— nationalism? vaccine nationalism - nationalism? vaccine nationalism is - nationalism? vaccine nationalism is the - nationalism? vaccine i nationalism is the usual nationalism, only about vaccines, and by that i mean

it�*s when countries act in ways they think our self interested, and acting in ways that prioritise their own citizens in their own country�*s interest over those of the rest of the world. {iii over those of the rest of the world. . ., , over those of the rest of the world. , ,�* world. of course countries' governments _ world. of course countries' governments are _ world. of course countries' governments are under- world. of course countries' governments are under a l world. of course countries' i governments are under a lot world. of course countries' - governments are under a lot of pressure from voters to prioritise those voters. yes, absolutely, and i _ prioritise those voters. yes, absolutely, and i think- prioritise those voters. yes, absolutely, and i think they| absolutely, and i think they are not only under pressure from the electorate, but there are some good moral reasons to prioritise your own, but there are serious limits on the acceptable forms of vaccine nationalism.— acceptable forms of vaccine nationalism. �* , ., ., nationalism. because the ma'or oint is nationalism. because the ma'or point is the d nationalism. because the ma'or point is the big d nationalism. because the ma'or point is the big countries �* nationalism. because the major point is the big countries with i point is the big countries with a lot of leveraged, a lot of money will be first in the queue, and yet if we are not all vaccinated, it gives much more chance for the virus to mutate, for new variants to emerge?— mutate, for new variants to emerue? . h , emerge? that's exactly right, so in addition _

the hoarding which we see in some countries, and some degree of nationalism may have been at work framing countries to join the covax facility in the first place. lowerand middle the covax facility in the first place. lower and middle income countries benefit in nationally self—interested ways by getting access to vaccines that otherwise they couldn�*t, and richer countries that joined the covax facility spread the risk by betting on a diverse portfolio of vaccines that the covax facility has orchestrated. , , , orchestrated. very briefly if ou orchestrated. very briefly if you don't — orchestrated. very briefly if you don't mind, _ orchestrated. very briefly if you don't mind, there - orchestrated. very briefly if you don't mind, there has l orchestrated. very briefly if- you don't mind, there has been you don�*t mind, there has been talk of a moral failure if rich countries do hog of the vaccine. we�*re several months into a rollout, do you still feel that is a risk? it into a rollout, do you still feel that is a risk?- feelthat is a risk? it is still a risk, it�*s a risk that is being realised right now, we are failing, and we haven�*t discovered and we haven�*t decided where the limits of acceptable vaccine nationalism lie. . ~ acceptable vaccine nationalism lie. ., ~ , ., acceptable vaccine nationalism lie. ., .

stay with us on bbc news. still to come: in the grip of a bitter arctic chill — southern and central us states are hit by snow and ice. we�*ll have the latest from kansas. nine years and 15,000 deaths after going into afghanistan, the last soviet troops were finally coming home. the withdrawal completed in good order, but the army defeated in the task it had been sent to perform. malcolm has been murdered. that has a terrible affect on the morale of the people. i'm terrified of the repercussions on the streets, one wonders who is next. gunfire as the airlift got under way, there was no letup . in the eruption itself. lava streams from . a vent low the crater

flowed down to the sea the east of the island, i away from the town for the time being. | it could start flowing again at any time. i the russians heralded their new generation space station with a spectacular night launch, they called it �*mir�* — the russian for peace. welcome back. very glad to have you with us. the latest headlines for you: more than a50 children reportedly killed or wounded in sniper fire in yemen and now the un warns of unimaginable humanitarian consequences, with the latest escalation of fighting. myanmar�*s military is warning anti—coup protesters could face up to 20 years in prison if they obstruct the armed forces. a south african corruption inquiry will ask the country�*s constitutional court to put its former president in jail. on monday, jacob zuma failed to appear before the commission

which is looking into corruption during his paul hawkins reports. for nine years, jacob zuma led south africa, but his presidency was dogged by accusations of corruption. namely, that he allowed the wealthy group to family to plunder state resources and influence policy in cabinet appointments, both deny any wrongdoing. appointments, both deny any wrongdoing-— wrongdoing. there is no minister— wrongdoing. there is no minister who _ wrongdoing. there is no minister who is - wrongdoing. there is no minister who is here, i wrongdoing. there is no l minister who is here, who wrongdoing. there is no - minister who is here, who was ever appointed by the group thes or by anyone else. nevertheless, for the past three years, the commission has been looking to allegations of corruption against the former president, who was legally required to appear before the commission on monday but failed to do so. instead, thejudge has asked the country�*s constitutional court to charge him with contempt of court. fine him with contempt of court. one ofthe him with contempt of court. one of the things _ him with contempt of court. one of the things to _ him with contempt of court. one of the things to do _ him with contempt of court. (he: of the things to do is him with contempt of court. (me: of the things to do is impose him with contempt of court. iez of the things to do is impose a

term of imprisonment on mr zuma, another would be for it to impose a fine. the zuma, another would be for it to impose a fine.— to impose a fine. the former president — to impose a fine. the former president said _ to impose a fine. the former president said he _ to impose a fine. the former president said he would - to impose a fine. the former i president said he would rather go to jail than appear before the commission. he believes justice is biased against him, and allegation thejudge and allegation the judge denies. and allegation thejudge denies. meanwhile, supporters of the former president were marching outside his rural home. the man himself, wild up inside. two years since he left office, but there is still some public sympathy for him. zuma is a freedom _ is a freedom fighter of everyone. he fights for this country to be what it is today. so for me to say tabernacle is to be sent to prison for three months, ah, i don�*t think it�*s an easy thing to say. —— sent for prison for three months. the means they are calling for

him to— the means they are calling for him to do— the means they are calling for him to do it is questionable, but i — him to do it is questionable, but i guess we will see. this is a volatile _ but i guess we will see. this is a volatile period _ but i guess we will see. this is a volatile period for- but i guess we will see. ti 3 is a volatile period for south africa�*s governing anc. other powerful figures also implicated in corruption are trying to regain control of the party in the country. president ramaphosa is still widely respected here, but with corruption still rampant and an economy battered by the pandemic, the anc�*s shadowy power struggles could yet unseat him. paul hawkins, bbc news. caroline davis met some of the first new arrivals to the uk facing new rules. a different arrival to the uk. some of the first passengers destined for quarantine hotels escorted out of the airport through photographers�* flashes and on to their rooms. coaches have been arriving throughout the course of the morning, bringing passengers from heathrow airport to the quarantine hotels. everybody on board will have declared that they�*ve been

in a red list country in the course of the last ten days. guests won�*t leave these walls for 11 nights or ten full days. but for those arriving today, there was some company outside their windows. how�*s the room? good, thanks. it's ok. wiehann meyer flew from south africa via qatar. he�*s starting a newjob here in march, and his visa only started today. he says that passengers that travelled from red list countries and those that didn�*t were together on the flight and in the airport. i was probably about two seats from someone that doesn�*t come from a red list country. we�*re all in the same vicinity, breathing the same air. he split the room with a friend for the 11 nights. we�*re either going to as really good friends or we�*re going to hate each other. so, i guess only time will tell. windows unfortunately don�*t open. it would have been nice to maybe get some fresh air in every now and then. i�*m not particularly looking forward to the next 11 days, but, yeah, just hoping it goes by quickly. there are no international flights into northern ireland or wales at the moment,

but those flying into scotland chun wong and his eight—year—old daughter flew in from america this morning to be reunited with his wife after 16 months apart. i got my covid shot already. whatever it takes to make everybody safe, i�*m all for it. they�*ll have to wait another ten days before all three can be together as a family again. there is a loophole for scottish arrivals. if they fly into england and they haven�*t come from a red list country, they�*re expected to isolate at home, not a hotel. the scottish government want them to be put up in english hotels. negotiations on that are ongoing. early indications suggest that the number of passengers flying into the uk today was low and that the queues were relatively short. but there are concerns that new checks will mean delays, which could be a risk to passengers and staff. every additional check the officer has to do slows up that transaction, increases the risk of infection to the officer and to the traveller from the officer.

and as those queues build, of course the different planes mixing with one another, that builds up and increases the risk from traveller to traveller that the virus willjust spread. the government say that every step is taken to reduce risks and to minimise any potential for passenger interaction, and that some airports — including heathrow — have introduced additional measures to separate passengers from red list destinations before immigration. the policy doesn�*t have an end date, and the number of countries on the red list could still get longer. so these hotels may well see more passengers through their doors in the next few weeks and months. caroline davies, bbc news. large swathes of the us are gripped in a bitter arctic chill after a powerful winter storm brought snow and ice to several south—central states. millions of people have been left without power — the national weather service says the situation is unprecedented. jeremy goodwin, television meteorologist at wibw—tv in kansas told us more. i haven�*t seen anything like this professionally.

i have been a broadcast meteorologist for about 25 years now. and tonight was the coldest day we have had in topeka, kansas, since just before christmas of 1989. so it is not record—breaking — records go back to the 18805 — but, you know, we�*re talking about three decades. certainly it is notable. but we�*re looking at low temperatures here in topeka, they�*ll be about —27.7 c, or —18 fahrenheit, and you have to go back 30 years to find a number that low. so, jeremy what do you think is going on? the polar vortex does not usually get down so far, does it? sure, it typically does not out. and i�*ll tell you what. in this area, we hadn�*t seen a temperature below 0 c since early 2019, and i really had to go back and look, and have we done this recently? no. for the last couple of years

the temperature is did stay up. the polar vortex if you will, will kind of roll across southern canada into saskatchewan, manitoba, near winnipeg, and to give us a shot of cold air that will last a day, maybe two days, we all complain fora minute, and it normally goes on its way. but in this case we�*re looking at staying below 0 c for two straight weeks. that has not happened in about a0 years. so it�*s not that the temperatures — the temperatures tonight are especially extreme. but it�*s the length of this cold outbreak — we haven�*t seen something as cold as that since 1983 where it was this cold for as long and it was much worse. and how much longer are you expecting it�*s a last and how are people coping with this? it is unusual, mike. we�*re looking at the temperature finally getting above 0 c here in topeka on friday of this week, and by then we will have gone 1a straight days, for two cold weeks, near freezing.

it has been almost a0 years since that is happened. jeremy goodwin from wibw—tv in topeka, kansas. that�*s it for now. thank you so much for watching. hello. well, it�*s frost—free out there again, second night in a row. it�*s certainly turned very mild across the uk. monday was a mild day and tuesday is going to be every bit as mild. but the mild south—westerly winds have also brought some rain. this is where our weather is coming from, all the way, in fact, from the south almost. last week, it was all coming out of eastern europe, those cold easterly winds, but a complete reversal in fact, over the next few days, not only is the weather going to be coming in from the south—west, these passes of mild air, towards the weekend, it looks like a dip in thejet stream will make the air come right from the south. so that means that those temperatures will shoot up to quite possibly 17 celsius. but at the moment, we have the mild south—westerly winds, and they are strong. off the coast of scotland, gusting to 65 mph.

on top of that, we�*ve got plenty of rain splashing its way through the country during the early hours. these are the morning temperatures between 5—10 celsius. so, on tuesday, the low pressure is sweeping just to the northwest of scotland. gale force winds there in the hebrides, gusting again to 65 mph and frequent heavy showers. now, this is a weather front here. it�*s just clearing east anglia and the south—east in the afternoon. it may take time before it clears away completely, and then behind it, it�*s a mixture of sunny spells and showers, and the temperature is between 10—12 celsius. so even for february, quite a mild day. and as i say, that rain will take time to clear away from the south—east. here�*s a look at wednesday�*s weather forecast. one low pressure moves away — in fact, it�*s over iceland — and another one replaces it.

in fact, we are going to see a series of low pressure coming our way, bringing spells of rain, weatherfronts, this is the beginning of that really unsettled spell of weather, which will then turn very mild weather as we head into the weekend. but look at wednesday, lots of showers, outbreaks of rain heading toward some southern parts of the country. temperatures, again, fairly similar around 10—12 celsius. now, the rise in the temperature will be very significant as we head towards saturday and sunday. that�*s the day where in some southern and eastern areas, it could hit 17 celsius.

this is bbc news,
