welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is nkem ifejika — our top stories: marching for their lives — survivors of the florida school shooting say they'll take their gun control campaign to washington. israel and iran trade insults — and threats — in a showdown at the munich security conference. a new russian doping scandal as an athlete at the winter olympics is suspected of failing a test. and the winner is... and the stars are out for the annual bafta awards — we'll have the winners and those who missed out, later. survivors of the florida school shooting are organising a national march on washington to demand tighter restrictions on gun ownership. they say they're determined

that the shooting will be a turning point in the us national debate on guns. the white house says president trump will hold a listening session on wednesday with a group of high school students and teachers. simon clemison reports. the rally before the rally — protesters are already taking to the streets. in fort lauderdale, close to the biggest us school shooting for some years, many spoke. but three words rang out. chanting: shame on you! to every politician who is taking donations from the nra, shame on you. next month they plan to march on washington calling for tighter gun control, they hope there will be protests in other cities on the same day. students organising the demonstration say they want the latest attack to be a turning point. what i am looking for is reasonable change within the united states congress and bills that are passed before i get back to school because this is not the time for inaction and debate,

this is the time for discussion and for all people that are americans to come together as americans through love and compassion. this event happened on valentine's day, so many people lost loved ones. our community and our nation have taken too many bullets to the heart and now it is time to stand up. last year, donald trump said he would never infringe on the rights to keep arms. he has since blamed democrats for not acting on gun legislation when they controlled congress during the obama adminsitration. democrats had criticised him in the wake of the tragedy. president trump, who has met people affected by the shooting and has also rebuked the fbi, after the organisation admitted it failed to act on a tipoff about the suspect, nikolas cruz. cnn has invited the president to a town hall event with the survivors on wednesday. there is school shootings in america and there is outrage that follows, the question is whether that will now turn into something else. simon clemison, bbc news. israel's prime minister benjamin netanyahu has launched a scathing

attack on iran, calling it the ‘greatest threat to our world'. in a speech in munich he accused the iranians of seeking to dominate the middle east through terror, and warned that israel would act if tehran tested its resolve. iran's foreign minister dismissed the speech as not worthy of a response. lyse doucet reports. in a volatile middle east, hostility between the islamic republic and israel has been a dangerous faultline. israel views iran as it's greatest enemy, denouncing it's landmark nuclear deal with world powers. now it's stand—off runs along syria, where iran holds growing sway. prime minister netanyahu came to munich to use this preeminent security conference as his stage. no doubt mr narif will brazenly deny iran's nefarious involvement in syria. iran also denies that it committed an act of aggression against israel last week that it sent a drone into our airspace to threaten our people.

well, here is a piece of that iranian drone, or what is left of it after we shot it down. these were the first images of the drone iran is accused of sending into israeli airspace last week. israeli jets retaliated. targeting iranian assets in syria for the first time. but syrian fire brought down an israeli warplane, the first time in decades its combat aircraft was shot down by enemy fire. today when iran's foreign minister took to the stage in munich, he didn't mention the israeli leader by name. you were the audience for a cartoonist circus. and then he fired back with barbs of his own. israel uses aggression as a policy against its neighbours and once somebody — the syrians have the guts to down

one of its planes, it is as if a disaster has happened. this disaster does mark a dangerous new turn in syria's destructive conflict and tensions have been multiplying in recent weeks. russia, the united states and turkey all have their own forces on the ground, all fighting on different frontlines. even before this dramatic war of words, this security conference was overshadowed by fears there could be an all—out war in the middle east, drawing in powerful players like israel and iran. no one wants to see a confrontation, but the risks are clearly great and growing. lyse doucet, bbc news, munich. russian officials have confirmed that one of their athletes at the winter olympics in south korea is suspected of failing a doping test. alexander krushelnitsky won a bronze medal in curling.

he has now left the olympic village and surrendered his accreditation. krushelnitsky is one of the individual athletes who was allowed to compete despite a ban on the official russian team because of an alleged state—sponsored doping programme. in a moment we'll hear from our correspondent steve mcdonnel in seoul but first here's what the ioc had to say. on the one hand, it is extremely disappointing when prohibited substances may have been used but on the other hand, it shows the effectiveness of the anti—doping system at the games which protect the rights of all the clean athletes. if this case is confirmed, if this case is confirmed, it will be considered by the oar implementation group chaired by ioc executive board member nicole hoevertsz which will report the ioc eb at the end of the olympic games. a lot of russian athletes weren't even allowed to come here and those who are participating

are doing so as individuals, technically, any medal they win is under the olympic flag with the olympic anthem played. but, now we have an athlete here who is said to have used this banned substance and some might wonder, why might a curling athlete be using a banned substance? how can it possibly help with curling? apparently, meldonium is a drug that can calm you, slow your heart rate down and maybe help with nerves. something that requires the concentration and a steady hand, a substance like this could actually help a curling athlete. you can see why somebody might want to use it but of course, he has only failed the a sample test and we are waiting to see the b sample test when it comes in. i suppose this is positive for the local testing authorities. i suppose it is good when you catch

someone who is alleged to be doping. yeah, that's right. the winter olympics was on trial, if you like, following sochi in this regard and the koreans leading the team there would be proud that they have caught this athlete and the international olympic committee would also be saying this shows we are getting tough on drug use. mind you, there has already been an earlier japanese athlete who was found to have used a substance which is thought to be a masking agent. what you would use to try and prevent people from seeing that you are using performance enhancing substances. so we have had at least two athletes at this stage with a cloud over them in terms of drug use but yeah, in terms of the testers, they would say that is a big tick in terms of their performance. streets around one of the most sacred sites for tibetan buddhism have been reopened to pilgrims after a blaze broke out on saturday evening. chinese state media said the fire injokhang temple, was soon put out.

however, tibetans living abroad said that photos and posts about the blaze were quickly being censored. laura westbrook reports. smoke fills the sky at one of the most holy places in tibet. this footage posted online shows the roof of the jokhang monastery in flames. chinese state media said no one was hurt and the temple in lhasa has now been reopened. but it is not known how much damage this thousand—year—old monastery has suffered. the sprawling complex covers more than six acres, official reports did not specify which part of the temple was damaged by the fire. that is because beijing maintains tight control of tibet. as the news of the fire spread on chinese social media, there were reports photos were quickly being taken down by authorities. you would think that this would be an issue where they would rush to show people, to reassure them that the temple has

not been badly damaged. but there is almost no news coming out at all in the last 2a hours. it is probably not the fault of the chinese, probably the flames spread from another building nearby. that is what we are guessing. but the fact that they were not able to put it out quickly is damaging for the chinese. it is unfortunate, it will set back relations again — especially since nobody knows what has been damaged and what has survived. tibetan buddhists consider this to be their most sacred site, travelling to frustrate themselves at the sakyamuni buddha, the founder of their religion. earlier i spoke with robert thurman, professor of indo—tibetan buddhist studies at columbia university, and co—founder of tibet house in new york. hejoined us from woodstock, new york. and explained the significance of the temple it's the most significant temple in tibet. it has a statue of the buddha dating from the buddha's time,

according to the tibetan belief, which was brought by the princess of tang dynasty when she married the emperor of tibet at that time, in the seventh century. it is considered very inauspicious that the fire would break out there just at a time where it is high time for the chinese government to begin a dialogue with his holiness the dalai lama to improve the situation in tibet. for a fire to happen in this very central location is very inauspicious and will worry people a great deal. on the internet, i saw a photo of an extensive flame and some sort of chinese soldiers standing around watching it but without a water or without doing anything. it was puzzling but very short. it was obviously a surreptitiously filmed video from a phone. it is odd that chinese are not making a concerted effort to explain the fire, to say it has been

controlled and put out and to show it, actually. it's very worrisome. that it is a key question i was going to ask. despite that troubles the chinese might have with tibet, they would want to preserve this kind of building, wouldn't they? certainly. it is of course a tourist centre for chinese tourists. the majority of tourists in tibet are chinese. it is an important site for them and of course, for tibetans, it is an absolutely important pilgrimage site. usually, there are long lines of people going there at all times. the particular roof i saw in flames is one of the central roofs over one of the central areas and it was quite a strong fire, i was quite shocked seeing it, i must say. there is a possibility, depending how bad the fire is, that some could be restored?

they will rebuild it, of course. all of these ancient buddhist temples have been destroyed by fire over the years. this one is particularly amazing because it was done moo years ago. it has stood the test of time. chinese recently renovated it. polished it up a little bit, about a decade ago. it isa it is a very important art historical monuments and so forth. hopefully the roof, although beautifully done and reflects traditional tibetan architecture and metalwork and so on, did not damage in some of the important statues. stay with us on bbc news, still to come: why this six year old boy's epilepsy can't be treated with an illegal drug — despite his parents protests. 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 was murdered. that has a terrible effect on the morality of the people. i'm terrified of the repercussions in the streets. one wonders who is next. as the airlift got under way, there was no letup in the eruption itself. lava streams from a vent low in the crater flowed down to the sea on the east of the island — away from the town for the time being, but it could start flowing again at any time. the russians heralded their new generation space station with a spectacular night launch.

they called it mir, the russian for peace. this is bbc news. the latest headlines: survivors of the florida school shooting are organising a national march on washington to demand tighter restrictions on gun ownership. israel and iran trade insults at munich. here in the uk the government has said it can't issue a medical cannabis licence for a six—year—old epileptic chid — despite calls from his family and a group of mps. alfie dingley, who's from warwickshire in central england, regularly suffers violent seizures. a cannabis based treatment he received in the netherlands improved his condition — but it's illegal in the uk. 6—year—old alfie dingley has a rare form of epilepsy and suffers up to 30 violent seizures every day.

to go through that once would be traumatising, but we're going through it sometimes every 7—10 days, and it's just absolutely horrendous. last september, the family moved to the netherlands so alfie could be prescribed medical cannabis oil. his parents say he went 2a days without having a seizure. they've now moved back to the uk, but cannabis oil is illegal in britain, so they want the home secretary amber rudd to give alfie a license to use it. it is thought this drug works with nerve receptors in the brain to help control the seizures. but the home office has ruled it out. they say... a group of mps want the home secretary to make

an exception for alfie. if we can find a way for her around the regulations that exist, and we believe that we can, she can issue a license to make sure that alfie can get this medicine. alfie's family have vowed to continue their battle, saying "you've got to fight, for your kids and we want to know that we've done everything we can". charlotte gallagher, bbc news. well for more on that story, i'm joined by mark cook, professor of neurology at the university of melbourne, and researcher into the treatment of epilepsy. first of all, how does this therapy work? the parts of the brain have receptors that respond to stimulation by the various active agents in cannabis. the most port in

one is thc. the brain is equipped with sensors that change excitability of the symptoms and might help some people be protected against seizures. during the period he was in the netherlands, his seizures reduced incredibly dramatically. we are seeing a lot of anecdotal information from young people particularly in had great response to cannabis and there are a lot of trials under way in some of these have shown, particularly in childhood epilepsy, that there are certainly people who can enjoy these medications. what is the rationale --1 medications. what is the rationale ——i of the rationale is —— what is the rationale in the uk. in it? is ita the rationale in the uk. in it? is it a drugs policy issue? was it to testing issue? in that not enough have been carried out to approve it asa have been carried out to approve it as a drug? it's a bit of both. no

doubt like in australia, there are regulations around drugs that are still contraband. regulations around drugs that are still contra band. as well, regulations around drugs that are still contraband. as well, there are issues with any new agent showing they are effective through clinical trials. and there are agencies involved, strong evidence that these treatments are genuinely effective. the difference with marijuana treatments is that there is a background of the safety of the agents. we know that the safety of them is pretty well—established. certainly there are problems but there are problems with medications anyway. making special dents —— dispensation is the way forward in this situation until standard processes a re this situation until standard processes are put in place. professor mark cook, thank you very much. rescue teams in western iran

searching for a passenger plane which disappeared with more than 60 people on board, have called off for their search for the night because of heavy snow. families have been gathering at a mosque close to the airport to get information about their loved ones. it's feared there are no survivors. the plane went down in the zagros mountains during a flight from the capital tehran to the southwestern city of yasuj. the islamic state group says it was behind the killing of five people at a church in the russian republic of dagestan. an attacker opened fire with a hunting rifle on worshippers as they were leaving a christian orthodox ceremony in the town of kizlyar. he was shot dead shortly afterwards by the security forces. two days after the brazilian president, michel temer, signed a decree giving control of security in the state of rio de janeiro to the armed forces, brazilian media say a prison in the city has been taken over by armed inmates who are holding a number of wardens hostage.

one of burkina faso's best known film directors, idrissa ouedraogo, has died following a stroke. he was 64. mr ouedraogo was one of a group of film makers who helped put his country at the centre of african cinema. perhaps his most famous film work was the 1989 film yaaba. the best of british film—making talent has been honoured at the baftas, with many of the stars using the spotlight to highlight the sexual harassment scandal which has gripped the industry in recent months. the big winner of the night was three billboards outside ebbing, missouri which won in five categories, while gary oldman was named best actorfor his portrayal of winston churchill in darkest hour. here's our arts editor will gompertz. his report contains some flash photography. the baftas 2018. part award ceremony, part platform for protest.

the wear something black dress code represents a collective stand against harassment and inequality in the workplace. there is definitely a different feel to the baftas this year. people are still coming to celebrate filmmaking at its finest but it is a sombre and serious mood with the time's up campaign and it does change the emphasis of the awards. it is notjust a case of who will win what, but who will say what. who will capture the mood and spirit of these times as oprah winfrey did at the golden globes? the answer turned out to be the best actress winner, frances mcdormand, who gave a mischievous, witty, potent acceptance speech. i have a little trouble with compliance. laughter. but i want you to know that i stand in full solidarity with my sisters tonight in black. i also want to say that i appreciate a well—organised act of civil disobedience.

power to the people. she won for playing a furious and grieveing mother in three billboards outside ebbing, missouri. start up a database, put every baby boy on it. as soon as he done something wrong, cross—reference it and make 100% certain it was a correct match, and then kill him. the american—set british film was a big winner with five awards, including best supporting actor for sam rockwell. lam humbled. best original screenplay for the film's london—born irish director, martin mcdonagh. and the top award, best film. what we are most proud of about this film, especially in this time's up year is that it is a film about a woman who refuses to take any ———— any more. played by a woman who has always refused to take any ————. and then there was the

leading actor award, complete with a dig at last year's oscars. the winner is frances mcdormand... nah, just kidding. the bafta goes to gary oldman. he won for this portrayal of winston churchill in the film darkest hour. you cannot reason with a tiger when your head is in its mouth. so grateful for this incredible honour. thank you. allison janney won best supporting actress for playing the hard—bitten mother in i, tonya. how old are you, honey? she's a soft 4. guillermo del toro won best director for his film the shape of water on what was a slightly disappointing night for this hotly tipped movie. perhaps it will be a different story at the oscars in a fortnight‘s time. and before we go, let's take

a look at these pictures. they show the incredible scenery of the changbai mountains in northeast china'sjilin province, which amazes thousands of tourists every winter. as you can see, the scene is shrouded in white steam rising from dozens of hot springs, making visitors feel like they're immersed in a wonderland. to keep the place looking special, the authorities set a maximum daily limit of 5,000 visitors. don't forget you can get in touch with me and some of the team on twitter, i'm @nkemifejika. good morning. it looks like the weather pattern

and weather type will change significantly over the week ahead. the past few weeks we have had fast—moving weather, a strong jetstream propagating across the atlantic with fluctuations between sunshine and it's noted that everything slows down over the next few days, the jet stream will weaken and change position and get more undulations. and it is under one of those that we induce this area of high pressure to build in the middle of next week. something we've not had much of in the past few weeks. not much sunshine around on sunday. we have some to the lee of high ground across parts of wales and the south—eastern. anglia got sunshine as well as north—east scotland though for many of us, cloud rolled in and lot of cloud at the moment so no frost. two weather fronts on the scene as well, the first one bringing most of the current rain and drizzle. in between the two we have a pocket of mild air. get sunshine in the west this time that will boost the temperature. a change of fortune on monday.

eastern scotland and eastern england are drab and dreary with a lot of cloud, rain and drizzle. dry and bright with a little sunshine especially in coastal areas and in northern ireland. ahead of the second band of rain that arrives later in the day. get some sunshine, 13 degrees in the east under the cloud and rain, only 7—9. those two bands of rain joined forces to bring rain for england on tuesday, probably from humber southwards. heavy for a while, easing off in the afternoon but a strong wind will push cloud through the midlands towards the west country. further west and north in particular the air will be drier with more sunshine around and decent temperatures. overnight clear skies, light winds and the temperatures will fall away. the rain peters out towards the south—east. we will have some cloud at times across southern areas but elsewhere we will be back in the blue with frost in rural parts — the first of a few frosty nights to come. a cold start on wednesday but brightening up with nice sunshine around for many. more in the way of cloud through the day at times,

wales, the midlands and southern england with sunny skies further north. by this stage the wind are light everywhere and you get some sunshine it will not feel too bad, but this temperatures will be around 7—8 degrees or so. some weather system threatened the coming from the north—west and bring back the sort of weather that we have been seen but they will be held at bay by the blocking area of high pressure so thursday and friday will still be drier. temperatures reaching perhaps 13 degrees at the beginning of the week and that mild start will turn chilly, particularly at night but it is becoming dry. this is bbc news. the headlines: survivors of the florida school shooting are organising a national march on washington to demand tighter restrictions on gun ownership. they say they're determined that the shooting — in which 17 people died — will be a turning point in the us national debate on guns. israel's prime minister benjamin netanyahu has launched a scathing attack on iran, calling it the ‘greatest threat to our world'. in a speech in munich he accused

the iranians of seeking to dominate the middle east through terror, and warned that israel would act if tehran tested its resolve. russian officials have confirmed that one of their athletes at the winter olympics in south korea is suspected of failing a doping test. alexander krushelnitsky won a bronze medal in curling. he has now left the olympic village and surrendered his accreditation.
