Thousands of people in florida, including survivors of wednesdays mass school shooting, have taken part in a rally to demand tighter gun controls in the United States. The event took place outside the Court Building in the city of fort lauderdale, a short distance from the school where a former student, nikolas cruz, killed seventeen people. Laura westbrook reports. Chanting no more outside the federal courthouse in fort lauderdale, this was the message to lawmakers. Among the protesters was emma gonzales, who took cover on the floor of the schools auditorium as a gunman started shooting. She had this to say to donald trump. 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 will happily ask him how much money he received from the National Rifle association. What shes referring to is the millions of dollars the nra has given towards the trump campaign. On a visit to the hospital where the victims of the attack are being treated, the president once again made no mention of guns or gun control. Instead, he says the problem is mental illness. Just a few kilometres south of where the protest is being held, a gun show is taking place. In the us, there are as many guns in circulation as people. The nra is the most powerful lobbying organisation in the United States and they have successfully resisted every move to tighten gun controls. And for their supporters, it is a fundamental freedom. When someone infringes a right for persons to keep and bear arms, then its an infringement on rights and civil liberties. That is a big problem. We will spend our time is at funerals. But after yet another school shooting, anger among the Younger Generation is rising. In fact, students across the country are planning a mass walkout of schools in april, the anniversary of the Columbine School massacre. They are demanding adults listen to them and tighten gun control. Laura westbrook, bbc news. Lets take a look at some of the other stories making the news.

Shuba krishnan has more. It was supposed to be a military mission to assess damage and provide support after a shocking 7. 2 magnitude quake. But it all went terribly wrong. The helicopter carrying mexicos interior minister and the 0axaca state governor crashed on top of two minibuses in a small village not far from the epicentre. 14 people were killed including a six month old baby. Remarkably, senior officials on board survived. The delegation had been touring 0axaca, the epicentre of fridays earthquake. While no deaths have been reported from the earthquake itself, it did leave nearly i earthquake itself, it did leave nearlyi million homes and businesses without power. Witnesses of the helicopter crashed that it could have been a power cuts that played a factor. They say it circled several times, raising thick clouds of dust and further reducing visibility. Translation the entire tower was without light, it was dark. We will have the update, we were going to sleep up there, we will all be up there but look what they did. The governor was supposed to come and help but what was the help . The aid we received. This was the aid . Mexican politicians have apologised for the accident but that wont do much to ease the pain felt by relatives mourning the loss of their loved ones. President Trumps National security adviser 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. Tensions between moscow and washington have also been evident at the conference. Our chief international correspondent, lyse doucet, is in munich. It is not the first time that senior us officials have accused president assads government and its main ally, russia, of being behind the use of chemical weapons in syria. We have recently a warning from the french president , emmanuel macron, saying that there was evidence that they would strike in retaliation to the use of chemical weapons. It is not the first time. But emmanuel macron, in his case, he said there was no proof what weve heard today from hr mcmaster, he said thatjudging by Public Records and by photographs, the evidence is clear. He didnt make clear which Public Record and photographs he was referring to. But 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 and unacceptable. The body of zimbabwes 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 . 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. It is a major departure from what zimbabweans are used to. Under president robert mugabe, Morgan Tsvangirai served as his minister, but it 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. Across the board, we across the boa rd, we have across the board, we have seen something that zimbabweans have never really seen. That is all the Political Parties coming together, putting their differences aside to celebrate the life of Morgan Tsvangirai. The Prime Minister has called for a new security treaty with the European Union after brexit, warning that lives could be at risk without full co operation. In a speech in germany, theresa may said new arrangements over working together should be effective by next year. Our Political Correspondent 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 britains 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. Shes 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 wasnt at war with the uk and didnt want to take revenge on the british people. He said the security bridge would be maintained, but you couldnt mix it up with other issues. A familiar message from the theresa may, the u. K. s leading the European Union but it doesnt mean Close Corporation needs to end. Conservative mps attending the conference here believe the speech is a good starting point for talks. Weve got to start getting into the detail of this. I think one thing we can do is improve our offer around defence and security, and i do think we need to have another look in the uk as to how we prioritise security. So its a pretty familiar message from theresa may. The uk is leaving the European Union but that doesnt mean that close cooperation needs to end. And its a blunt message too, saying to europes leaders dont let your ideology get in the wake of the safety of our citizens. The government hopes todays speech will show its acting responsibly, not wanting to drag the important issue of security into fraught brexit negotiations. Vicki young, bbc news, munich. Stay with us on bbc news, still to come i was the best figure skater in the world at one point in time. She was famously linked to an attack on a fellow skater now the story of Tonya Harding gets the hollywood treatment. We speak to the films stars. 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. Im 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.

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 Trumps National security adviser has said its time the world held syria to account for using chemical weapons. World leaders at a major security conference in munich have heard that wars have caused the first increase in worldwide hunger in decades. Our chief international correspondent, lyse doucet, heard from the executive director of the world food programme, david beasley. The Munich Security Conference is 110w the Munich Security Conference is now considered the premier gathering for defence and diplomacy chiefs to discuss major Security Issues of the day. You wouldnt consider Security Issues, they are now at the top of the agenda. Take a basic one like food. It is not only used as a weapon in war, but hunger is increasing for the first time in a long time, and that has security implications. To discuss this is the head of the world food programme. The new statistics out on the state of Global Hunger are very distressing. What are you learning . The great news is for the last 30 years , we the great news is for the last 30 yea rs, we have the great news is for the last 30 years, we have reduced hunger around the world. The bad news is the last couple of years the rate has gone back up and that is because the war and conflict. 82 of expenditure is in warzone and conflict. 82 of expenditure is in war zone places like yemen, syria, south sudan, somalia, iran, afghanistan. It is man made conflict and renew compound that with climate change, it is a disaster in the works. We are dealing with this and every time you have hunger, you have a migration. We know that every 1 increase of hunger, there is a 2 increase of hunger, there is a 2 increase in migration. You see why the europeans in the us are coming together because it is in their National Security interest to address Food Security. You find you are inside the Munich Security Conference, so are inside the Munich Security Conference, so many are inside the Munich Security Conference, so many high level people can make things happen, they are listening to this messagem has been quite remarkable to see the foreign ministers, the president s, the Prime Minister is clearly understanding that Food Security is critical. If people dont have food, they will either fight or flee. We are addressing this very clearly. We can use food as a weapon peace, a weapon of reconciliation, a of Sustainable Development let isis, al qaeda, terrorist groups use it at a weapon of division, war. Food is increasingly used, we have seen in yemen, syria. How can you tackle that . When you control food, you control a lot. We come in here making their innocent victims of conflicts receive the food they need to they dont have to yield to extremist and terrorist groups. The groups will deprive people of food and we havent fed your little girl 01 and we havent fed your little girl ora and we havent fed your little girl or a week or two, you will fall prey. We are there, and that is what we are all about. Bringing safety and security in regions that otherwise are in chaos and conflict. When you put yemen on the table, syria on the table, when we feed assyrian in syria, it is about 50 cents per day. When that seems assyrian refugee end up in early and on munich, total humanitarian cost is 50 euros per day, and that syrian refugee wants to be at home, not in another country. Getting more fruit assyrian in besieged areas . Syria is a very complex situation. Some days we feel we are making great headwear but there is still perceived areas. We are feeding several million syrians on her red day. We have been doing airdrops, airlifts and everything we can to wring some food into these very difficult and comics areas. The complicity in syria is very difficult because you have iran, hezbollah, syria, the us, russia, turkey and what we are asking in the wars, in the conflict, let people have a normal life again so let people have a normal life again so childrens let people have a normal life again so child rens dreams let people have a normal life again so childrens dreams can come true again are not the totally devastated and destroyed because of war. Who are the new food could be so complicated. Thank you so much for joining us here. You have a snapshot of how food is playing such a Critical Role when it comes to the major security will stop it shouldnt be that way, but thats a reality and that is what they were discussing in munich. Now, day 9 of the Winter Olympics in south korea are under way with no medals up for grabs so far, but heres some of the highlights from day 8. Norways Marit Bjorgen has skied her way into the record books as part of the winning team in the ladies 4x5km Cross Country event. She is now the joint most decorated winter olympian of all time with 13 medals to her name. And great britains Lizzy Yarnold successfully defended her skeleton title claiming gold ahead of team mate laura deas, who got the bronze, which alongside a bronze for izzy atkin in the ski slopestyle event, marked great britains most successful day at a Winter Olympics. And in the ski jump, polands kamil stoch retained his large hill individual title with a leap of 136. 5 metres. To keep up to date with the latest action, just go to the bbc sport website. While many eyes are focused on this years Winter Olympics, one of the most hotly tipped films for sunday nights British Academy of film and Television Awards is i, tonya, based on events linked to the Winter Olympics of 1994. Its 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 plays her mother. 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 wasnt 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 theirfriends knee . The juxtaposition of everyones 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 doesnt have their ups and downs . I made you a champion knowing youd hate me for it thats 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 her a three dimensional character. She wasntjust a monster. How old are you, honey . Shes a soft four. Having been a figure skater myself, i know how expensive it is to have custom skates and have the skating costumes. I know what it took for my parents to get up at 5 00 in the morning so i i knew ifelt like i could tell her side of the story. What can you tell us about Tonya Harding . Hmm, i dont know a tony harding. Arent you her bodyguard . As a young producer and actor in the business, do you think the game is still rigged against women . Theres far more female driven content, female led films now than even when i started and i havent even been doing it this long. But still, is it enough . No. We still have the statistics are so imbalanced, i think its going to take a while. But, yeah. 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. Our science correspondent pallab ghosh reports. Picassos crouching woman worth millions. A painting from his blue period. But theres 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 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 womans 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. The mexican muralist artist. Here at the harry ransom center, 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. So, this figure here is oscar levant, who was a friend of George Gershwin, but also a rival. And 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 thats 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. Its a collaboration that the team wants to extend to more galleries. Many of these paintings are waiting to tell their secrets and so, with the x ray fluorescent 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. Dont forget you can get in touch with me and some of the team on twitter. Im nkemifejika. Hello there, good morning. Its going to be a bit chilly out there first thing this morning. Clearer skies in many areas to follow the sunshine that we had yesterday. But there wont be as much sunshine today because all this cloud that has been filling in the atlantic is going to be slowly heading our way. And weve already seen some of that cloud arriving across wales and the south west, so not as cold here. Less reliable cloud elsewhere means a touch of frost especially for scotland and down the eastern side of england, and maybe some patches of fog too. We are going to get some milder air eventually today if not today, then tomorrow. This envelope of milder air coming in between these two weather fronts here and its this first one that we need to look at for today because it will eventually bring more rain and drizzle into western areas. Most places, though, will start the day dry. There may be some early sunshine across some eastern parts of england. The best of the sunshine probably for north east scotland. Should be a lovely day here. A lot more cloud spilling our way, though, through the day and especially in the afternoon, the cloud thickening up to give some more rain and drizzle, particularly across Northern Ireland. But temperatures probably around 10 or 11 degrees. Ironically, where its going to be brighter, its going to be cooler towards the north east of the uk. Now into the evening and overnight, well, we find this rain and drizzle continuing to push its way eastwards pretty much across the country. Not much rain, though. There may well be some misty, murky weather over the hills and a lot of cloud overnight. So as a result, its going to be a much milder night, and temperatures typically 5 or 6 degrees, so no frost early on monday morning this time. Instead, a different look to the weather for eastern scotland and down the eastern side of england, where we are going to have some misty, murky conditions and some rain and drizzle. If there is any sunshine, maybe some of these western coasts, perhaps antrim and down, ahead of some more rain coming in Northern Ireland later. But a mild day temperatures about 10, maybe as high as 12 degrees or so. But that mild air getting squeezed away. Colder air is going to be spilling our way over the coming few days whether it comes in from the east or from the west. And we start tuesday with some thicker cloud, some outbreaks of rain down the eastern side of england, for a time in eastern scotland. That rain tends to peter out, mind you. More sunshine for Northern Ireland and for scotland, perhaps some other western coasts of england and wales, but already turning cooler out towards the east underneath all that cloud. And thats the way temperatures are going to be going. It is going to be turning cooler. High pressure, though, building in over the uk whether it is this one from the atlantic or this one from scandinavia, not a great deal of breeze out there and where you have some breaks in the cloud, there may well be some frost in the outlook. After a mild start to the week, though, it will gradually turn a bit colder. The chance of some of easterly winds, but it should be turning dry. This is bbc news the headlines.
