survivors of wednesday's mass school shooting in florida have taken part in a rally to demand tighter gun controls in the united states. the event took place in a short distance from the school where a former student, nikolas cruz, killed 17 people. there was strong criticism of president trump and other politicians for taking campaign contributions from the powerful national rifle association. if the president wants to come up to me and tell me to my face that it was a terrible tragedy and how it should never have happened and maintain telling us how nothing is going to be done about it, i would happily asked him how much money he received from the national rifle association. to every politician who is taking politicians from the nra, shame on you. we will bring you more

on that later in the programme. the mexican defence secretary has apologised for a helicopter accident that killed 14 people on friday in the southern state of oaxaca. the military helicopter was carrying two senior mexican politicians to the area which had been hit by a 7.2 magnitude earthquake. the pilot lost control of the helicopter as it approached the village of santiagojamiltepec in the dark, raising a thick cloud of dust. the aircraft landed on top of two packed minibuses. a six—month—old child was among those killed. local residents expressed their anger. translation: the entire town was without light. it was dark. we were happy up without light. it was dark. we were happy up there. we were going to sleep up there. we were all going to be up there. but look what they did. the governor was supposedly coming to help. but what was the help, the aid we receive? this was the aid? ——

received? president trump's national security advisor has called on world leaders to hold the syrian government to account for its continued use of chemical weapons. speaking at the munich security conference, hr mcmaster says it is clear that such weapons are still being deployed by the assad regime. it is time for all nations to hold the syrian regime and its sponsors accountable for their actions and support the efforts of the organisation for the role of it and of chemical weapons. —— the prohibition of chemical weapons. the nonproliferation regime is under tremendous pressure, not only from the use of chemical weapons, but also from the development and proliferation of nuclear weapons. it needs our unequivocal support. our chief international correspondent, lyse doucet, is in munich for us. it is not the first time that senior

us officials have accused president assad's government and its main ally, russia, are being behind the use of chemical weapons in this area. we have recently a warning from the french president, emmanuel macron, saying there was evidence that they would strike in retaliation to the use of chemical weapons. it is not the first time. emmanuel macron, in his case, so there was no proof what we have heard from a chain of mcmaster, he said thatjudging by public records and by photographs, the evidence is clear —— hr mcmaster. he did not make clear which public record or photographs he was referring to. we do know that time and again, every time this accusation is made, the syrian government denies it and they have responded when there was the warning from emmanuel macron, faisal mekdad, the deputy foreign minister,

said that the syrian government did not possess chemical weapons and he described them as immoral. yet the situation on the ground in this area is as complex and complicated as it ever has been. it is wars within wa i’s ever has been. it is wars within wars in syria now as this conflict approaches the end of its seventh year. we have seen in recent weeks and invasion by turkish troops into the north of syria. there have been israeli airstrikes against is reign in and syrian positions. the syrian air force in and syrian positions. the syrian airforce has shut in and syrian positions. the syrian air force has shut down a russian and israeli fighter jet —— air force has shut down a russian and israeli fighterjet —— errani on. this is at a time when the syrian air force and russian warplanes have been unleashing more airstrikes in the last rebel held province of idlib. there has been intense fighting but bear in the north of syria andy last around damascus —— enclave. in both areas

that have been repeated allegations that have been repeated allegations that the syrian government is using chlorine gas. four ring gas is not on the list of banned chemicals. i have to say that i was in this area for three weeks injanuary. it repeated allegations and denials. we go back to our top story. people rallying in fort lauderdale after that mass school shooting that killed 17 people. cindy gerhardt is the president of the florida parent teacher association. thank you forjoining us on bbc news. a few moments ago, before you join us, we hope from emma gonzalez, incredibly passionate, incredibly angry, and frustrated, and i expect speaking for many students there. do you think it is an exaggeration to say that a generation is feeling let down there in florida? absolutely

not. i believe that the scales have now been tipped. i believe that this is probably going to be the catalyst that propels us forward to actual change. i'm sad that it had to come to this, but i do believe that is where we are, that is what we are facing. what is that change, what is that she's going to look like?” hope that the change begins with honest dialogue, that we can actually start having a conversation that there has to be compromise. there are semi— facets to what needs to be changed, whether it is focusing on addressing mental health issues with our youth, because of the crisis they are going through in their personalise the come out through anger and depression, we just seem to ignore that. we spend oui’ just seem to ignore that. we spend ourtime just seem to ignore that. we spend our time focused on pushing them to xl and to assess them and to test them, and our councillors no longer

have the opportunity to become counsellors, to be counsellors, to listen. they have become test administrators. i believe mental health is a huge element in what the solution can be. obviously, having the honest conversation about responsible gun legislation, it seems that both sides battle and no one wants to find a compromise. we have got to fix that. we have got to start having open, honest conversations and be open to compromise. you say that would compromise. you say that would compromise so many times, but, of course, on the other side there isn't any compromise. it is a zero—sum game for the other side. they believe any encroachment on their rights is too much. absolutely. it seems that we go through a cycle. we can predict exactly what will happen everytime there is another massacre. whether it is in las vegas or in a school or a church, we can predict exactly what is going to happen. we will

have the news, the 2a hour news cycle, then it goes to thoughts and prayers. then it is not the time for the political discussion on this. and then slowly we become complacent, it is not the top news story, and then there is another massacre. it is time for us to say there is not going to be any more. the cry you heard throughout the rally today was no more. every time i have been near a microphone it is no more. which child are we going to suggest that that will be the one that will be the answer? we have said enough blood. there has been enough. the quota has been met. it is time for real change. we appreciate you joining us. thank you very much. brendan cox, the widower of murdered british politician, jo cox, has announced he's standing down from two charities set up in her memory. it follows historic allegations of inappropriate behaviour with a female colleague. in a statement, mr cox said during his time

at save the children, he behaved in a way that had caused some women hurt and offence. he said it was never malicious but it was certainly inappropriate. the israeli air force has carried out raids in the gaza strip following an explosion near the border in which four soldiers were hurt. an israeli military spokesman said six hamas military targets were hit, including a tunnel. it's not known if there are any casualties at this stage. around 100 neo—nazis have held a torchlit march through the bulgarian capital sofia, to honour a bulgarian nationalist leader during the country's second world war alliance with the nazis. the event, held for lieutenant—general hristo lukov, went ahead despite condemnation from the city's mayor and two us congressmen. the march has been held annually since 2003. the body of zimbabwe's opposition leader, morgan tsvangirai, has arrived back in the country

following his death from cancer in south africa earlier this week. he was 65. hundreds of his supporters were at the airport in harare to pay their respects our correspondent in harare is shingai nyoka. he arrived at the airport where hundreds of supporters were there to meet him. his body was then escorted to the military barracks where it will lie in state until tomorrow. what we understand is that there will be a church service at about 12 gmt tomorrow, followed by a public service, a memorial service on monday, and then finally his body will be taken to his village, which is about four hours outside the capital. he will be laid to rest there. this is a state assisted funeral, not a state funeral, in that case he would have been buried at the national heroes acre. how would you describe the mood in

zimbabwe? how would i describe the mood in zimbabwe? well, the supporters were obviously very excited to have his body back. they almost broke down the hangar trying to get his body. but zimbabweans have been in a very sombre mood, remembering the legacy that he had. he has been in politics here in zimbabwe were about 20 years. he has led the movement for democratic change for all of that time. he is the figurehead for the opposition and many people are wondering what will happen to the opposition now that he has passed away, given that in about four months because time the country will be heading for elections. how would those who so forcefully opposed morgan tsvangirai and everything he stood for, how are they dealing with here is death and they dealing with here is death and the outpouring of respect you have been describing? it is a major

departure from what zimbabweans are used to. under president robert mugabe, morgan tsvangirai served as his minister, but there was a very acrimonious relationship between the parties. what we have heard at the next few days from the president, he described him as a son of the soil. they said they might even consider conferring and other honour on him, the relationship between the military and the party have always been tenuous. they hailed him as a man who contributed to democracy and push for free and fair elections across the country. all the political parties coming together, putting their differences aside to celebrate the life of emmerson mnangagwa. stay with us on bbc news

world news. can you see anything unusual about this picasso? will uncover the mystery hiding yani masterpiece. —— hiding behind a masterpiece. 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: students from the florida school where 17 people were killed in a mass shooting this week have taken part in a rally demanding tighter gun controls. president trump's national security adviser has said it's time the world held syria to account for using chemical weapons. we're taking you back to this weekend's security conference in munich — where the british prime minister, theresa may, has called for a new security treaty with the european union after brexit. she warned that lives could be at risk without full co—operation. vicki young reports from munich. in defence and security of the uk is a significant player.

the prime minister hopes that will get her a special deal. she arrived in munich keen to lay out britain's contribution. generous spending on defence and expertise it wants to share even after brexit. theresa may urged the eu to take a practical approach. this cannot be a time when any of us allow competition between partners, rigid institutional restrictions or deep—seated ideology to inhibit our cooperation and jeopardise the security of our citizens. she's calling for a new security treaty so that the close partnership can continue. failure to agree one would have damaging consequences, she said. we must do whatever is most practical and pragmatic in ensuring our collective security. those who threaten our security would like nothing more than to see us fractured. some listening to this were left bewildered. the brexit decision from the point

of view of us inside the eu is extremely regrettable. things would be so much easier if you stayed. so here comes the questions... applause mrs may pointed out that brexit was a democratic decision politicians should respect. one senior brussels figure seemed to agree. the commission presidentjean—claude junker said the eu wasn't at war with the uk and didn't want to take revenge on the british people. he said the security bridge would be maintained, but you couldn't mix it up with other issues. afamiliar a familiar message from the theresa may, the u.k.'s leading the european union but it doesn't mean close corporation needs to end. also a

blunt message, saying to europe's leaders, don't let your ideology get in the way of the safety of our citizens. the government hopes today's speech is acting responsibility —— responsibly. not wanting to drag the issue of security into frought brexit negotiations. the carl vinson, one of the us navy's longest serving active carriers, is docked off the coast of the philipinne capital manila this weekend. officials say they are conducting a routine mission in the south china sea. the contested waterway is believed to hold vast oil and gas deposits and is the route by which five trillion us dollars worth of trade passes annually. our philippines correspondent howard johnson has been onboard the carl vinson for a closer look. we are on the flight deck of the uss carl vinson. it is one of the largest aircraft carriers, and why did today and why have the media been invited on? quite simple, a pr

exercise to show they are present in the south china sea, the disputed waters where we have seen china tilting up sandbanks and reefs into artificial island. they have been installing military hardware, they have laid runways and they have even used a coastguard to defend their islands. that has unsettled countries like america, uk and australia who believe in free passage of these waters. in other reasons why the americans here is because they want to win support from the philippines in recent years we have seen the country has pivoted away from america geopolitically and we have seen president rodrigo duterte saying harsh words about america and trying to improve ties with china to increase aid funding and investment in the country. in fa ct, and investment in the country. in fact, in the last month, we have seen fact, in the last month, we have seen china and the philippines holding bilateral meetings to look at ways of exploring the south china sea as far as research and exploration of those oil and gas reserves a re exploration of those oil and gas reserves are concerned. after this

exercise, the uss carl vinson will head to vietnam, a first for the communist country and former foe of the united states. new scanning technology has revealed a painting underneath the famous picasso work — "a crouching woman". the picture underneath, is of the catalan landscape and is thought to have been painted by a student. it seems that picasso used the shape of the landscape as inspiration for his subject's hunched pose. the discovery has been unveiled at an international science conference in austin texas from where our science correspondent pallab ghosh reports. picasso's crouching woman — worth millions. a painting from his blue period. but there's more to it than meets the eye. the conservators at the gallery analysed it with a new type of scanner, and this is what they discovered. underneath it is a painting of the barcelona landscape by a fellow artist. but turn it 90 degrees and bring back the crouching woman, and you can see that picasso has used the landscape

as the basis of his painting. it helps date the painting, it helps determine where the painting was made. but it also gives us a sense of the artist with whom a particular painter was engaging. and i think these insights do help ask us new and more interesting and more scientifically accurate questions. the contour of the hills in the background becomes the crouching woman's back, and she takes on the shape and form of the catalan countryside. until now, only the wealthiest galleries could afford to scan, and even then, it was only for great works of art. but the new system is cheaper and portable, and so can be used by anyone to find the secrets behind any painting they want. here at the harry ransom centre, the curator has questions about this portrait of the american composer, george gershwin. in particular, whether a friend in the front row was painted out and seated further back because he fell out of favour. this figure here is oscar levant, who was a friend of george gershwin,

but also a rival. so stories have circulated for years that perhaps he, as the only recognisable figure in the second row, was perhaps moved — demoted, as it were — from appearing in the first row. so that is one of the questions we can potentially find out with this technology. can i take a look? tracy has asked the team that developed the scanning system to help her answer that question. they scan each stroke of the brush, millimetre by millimetre. it's a collaboration that the team wants to extend to more galleries. many of these paintings are waiting to tell their secrets, so with the x—ray flourescent spectrometer, we can help them talk to us more. the team hopes the widespread use of their scanners will increase our understanding of artists, their thought processes and the way they worked. while many eyes are focused on this year's winter olympics,

one of the most hotly—tipped films for sunday night's british academy of film and television awards is ‘i, tonya,‘ based on events linked to the winter olympics of 1994. it's a biopic about the american figure skater tonya harding, who became notorious for her link to an attack on a fellow skater. margot robbie plays the disgraced tonya, and allisonjanney her mother — and both have received bafta nominations. our arts editor will gompertz has been to meet them. i was the best figure skater in the world at one point in time. 4.8. how do i get a fair shot here? it wasn't about telling the tonya harding story. the haters always say, tonya, tell the truth. we have all these unreliable narrators telling completely contradictory versions of the exact same event. i mean come on, what kind of friggin' person bashes in theirfriend's knee? the juxtaposition of everyone's different

point of view and story is where the dark comedy comes in. where you see my character throw a knife at tonya. and then you cut to me saying, you know, what family doesn't have their ups and downs? i made you a champion! knowing you'd hate me for it. that's the sacrifice a mother makes. i wish i had a mother like me instead of nice. you cursed me. in the movie, you assault your daughter on more than one occasion, and yet her mother in real life denies it happening. i told her side of the story very well. i think i, i understood, i had to make hera three—dimensional character, she was just a monster. how old are you honey? she's a soft four. having been a figure skater myself, i know how expensive it is to have customs gates and have the skating costumes. i know what it took for my parents to get up at five in the morning. i felt like i could tell her side of the story. what can you tell us

about tonya harding? i don't know about tonya harding. aren't you her bodyguard? as a young producer and actor in the business, do you think the game is still rigged against women? there's far more female driven content, female lead films now than even when i started, and i haven't even been doing it this long. still, is it enough? no. we still have... the statistics are so imbalanced. i think it's going to take a while. but, yeah. don't forget to go to our website. and you get in touch with me and some of the team on twitter, i'm duncangolestani. it's going to be a bit chilly out
