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 her 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 in this country to keep and bear arms, then its an infringement on rights and civil liberties. That is a big problem. We will spend our times 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 High School massacre. They are demanding adults listen to them and tighten gun control. Laura westbrook, bbc news. 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, h. R 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. Lets take a look at some of the other stories making the news. 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. Its 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 nationalist leader who formed an allian with the nazis during the second world war. The event, held for lieutena nt general hristo lu kov, went ahead despite condemnation from the mayor and two us congressmen. The march has been held annually since 2003. A worldwide search is under way for nirav modi, a billionaire indian jeweller accused of cheating the state owned Punjab National bank out of nearly 1. 8 billion dollars. Its been reported that mr modi, whos achieved notoriety in india, left the country just days before the start of the investigation into him. 14 people have been killed, including a six month old baby, when a mexican military helicopter, carrying top officials surveying the damage from an earthquake, crashed in a small town in the Southern State of oaxaca in mexico. 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 farfrom 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 nearlyi million homes and businesses without power. Witnesses of the Helicopter Crash say 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 town was 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 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. Shuba krishnan, bbc news. 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 sixty five. 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. 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 for 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 last few days from the president , he described him as a son of the soil. They said they might even consider conferring another honour on him, the relationship between the military and the party has always been tenuous. They hailed him as a man who contributed to democracy and pushed for free and Fair Elections across the country. 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 President , jean 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. 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.

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 now considered the premier gathering for defence and diplomacy chiefs to discuss major Security Issues of the day. Things you wouldnt consider Security Issues 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. David, 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 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 our funding now, expenditure is in war zone places like yemen, syria, south sudan, nigeria, somalia, iran, afghanistan. Its man made conflict and when you compound that with climate change, its a disaster in the works. We are dealing with this and every time you have hunger, you have a migration. We know for every 1 increase of hunger, theres a 2 increase in migration. So you now see why the europeans in the us are coming together because its in their National Security interest to address Food Security. You find here inside the Munich Security Conference, so many high level people can make things happen, theyre listening to this message . Its been quite remarkable to see the foreign ministers, the president s, the Prime Ministers is clearly understanding that Food Security is critical. If people dont have food, they will either fight or flee. It is one of the two. We are addressing this very clearly. We can use food as a weapon of peace, a weapon of reconciliation, a weapon of Sustainable Development let isis, al qaeda, terrorist groups use it as a 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 can control a lot. That is the beauty of the world food programme. We come in here making their innocent victims of conflicts receive the food they need so they dont have to yield to extremist and terrorist groups. The extremist groups will deprive people of food and we havent fed your little girl or a week or two, you will fall prey. You will sign up. We are there, and that is what we are all about bringing safety and security in regions that are otherwise in chaos and conflict. When you put yemen on the table, you put syria on the table to give you an example when we feed a syrian in syria, it is about 50 cents per day. When that same syrian refugee end up in munich, total humanitarian cost is 50 euros per day, and that syrian refugee wants to be at home, not in another country. You are getting more food to syrians in besieged areas . Syria is a very complex situation. Some days we feel we are making great headway, but there is still perceived areas. We are feeding several million syrians on any given day. We have been doing airdrops, airlifts and everything we can to bring some food into these very difficult and complex areas. But the complicity in syria is getting very difficult now 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 childrens dreams can come true again and not be totally devastated and destroyed because of war, conflict and hunger. Who ever knew food could be so complicated. Thank you so much forjoining us here. You have a snapshot of how food is playing such a Critical Role when it comes to the major security. It shouldnt be that way, but thats the reality and that is what they were discussing in munich.
