welcome to bbc news. hundreds of thousands of students and campaigners, have gathered in cities across america, for rallies pushing for tougher gun laws. the protest called march for our lives, is being led by survivors of the massacre at a school in parkland in florida last month. they've been addressing crowds around the country, vowing to "stop at nothing" until lasting change is made. here's our north america correspondent gary o'donoghue. they came from across the country, bringing their message to the centre of power in the nation's capital. one of the biggest gun control demonstrations in years. parents, students, teachers, with one unified message: put an end to school shootings. we are marching because it's time for a change. i don't want to be a teacher that has guns in my building.

no guns in schools, no guns in churches, no guns in the workplace. one of those determined to make the march today was lauren. she was just six when 20 of her school friends died in the shooting at sandy hook elementary school, in 2012. it's fairly depressing because it's like this should have stopped a while ago. even though it's been very consistent. really, it should just end. america is used to school shootings, but the murder of 17 students and teachers at the parklands school in florida on valentine's day has galvanised a new generation to take direct action. parklands students have already affected changes in the law in florida and as the president was heading south to his florida home, students from there came to washington to ask congress to do more. they know it is coming, they know that there if there is no assault weapons ban passed,

then we will vote them out. cheering. they know that if there is no tightening of the background checks, we will vote them out. cheering. they know that if there is no shrinking of magazine capacity, then we will vote them out. scenes like this have been replicated all over the country with marches from los angeles to boston. and it's not just confined to america. across the uk, young people marched in solidarity. congress has passed modest measures in the past few days but they go nowhere near the kinds of sweeping reforms these protesters are demanding. gary o'donoghue, bbc news, washington. parkland shooting survivor emma gonzales addressed that march in washington, and paid tribute to her 17 fellow students who died in the attack. six minutes and about 20 seconds. in a little over six minutes, 17 of our friends were taken

from us, 15 were injured. and everyone, absolutely everyone, in the douglas community, was forever altered. everyone who was there understands. everyone who has been touched by the cold grip of gun violence understands. for us, long, tearful, chaotic hours in the scorching afternoon sun were spent not knowing. no—one understood the extent of what had happened. no—one could believe that there were bodies in that building, waiting to be identified for over a day. no—one knew that the people who were missing had stopped breathing long before any of us had even known that a code red had been called. no—one could comprehend the devastating aftermath or how far this would reach or where this would go. for those who still can't comprehend, because they refuse to, i'll tell you where it went. right into the ground, six feet deep. six minutes and 20 seconds with an ar15 and my friend, carmen, would never complain to me

about piano practice. aaron feis would never call keira miss sunshine. alex schachter would never walk into school with his brother, ryan. scott beigel would neverjoke around with cameron at camp. helena ramsay would never hang out after school with max. jean montalto would never wave to herfriend, liam, at lunch. gina montalto would never wave to herfriend, liam, at lunch. joaquin oliver would never play basketball with sam or dylan. alaina petty would never... cara loughran would never... chris hixson would never... luke hoyer would never... martin duque would never... peter wang would never... alyssa alhadeff would never... jamie guttenberg would never... meadow pollack would never... and we'll find out how this story — and many others — are covered in tomorrow's front pages. at10:30 and 11:30 this evening in the papers. my guests tonight are

rachel cunliffe, comment and features editor at city am and political correspondent at the financial times, henry mance. another very sad story. tributes have been paid to a french police officer, who died saving the lives of hostages in a supermarket siege in the town of trebes yesterday. lieutena nt—colonel arnaud beltrame, was shot and stabbed and later died of his wounds. three other people were also killed. ina in a series of attacks. president macron, said that he showed "exceptional courage," and called him a "hero". lucy williamson reports. this attack has become not the story of a gunmen but the story of a hero. arnaud beltrame. the man who made astonishing bravery seem natural, almost routine. flags were lowered to half—mast at his former base today and at units across the country to pay homage to their colleague and friend. he was remembered here, too, by those who never knew him.

another tribute every few minutes. he is a hero, for me, because he's given his life, for a lot of people. he knew it was dangerous, what he did, but he did it. the gendarmerie said arnaud beltrame's death was a reminder of their daily commitment to protect the people. for the people themselves, his actions are a defiant response to the country's would—be attackers, a reminder of the best of france. today, the site of so much drama was a chilled and empty crime scene. its car park still littered with the debris of a terrified and desperate flight. inside this building yesterday, arnaud beltrame offered up his life up his life in place of others'. his mobile phone, secretly connected to colleagues outside, giving the operation a vital edge. his brother told french radio that

arnaud had died a hero. translation: what he did was beyond the call of duty. he gave his life for strangers. he must have known that he didn't really have a chance. if that doesn't make him a hero, i don't know what would. his mother said she wasn't surprised at what her son had done. "that's the way he lived and the way he worked," she said. "he used to tell me he was just doing hisjob, nothing more." that's not how it feels today. lucy williamson, bbc news, carcassonne. i'm joined in the studio by benedicte paviot, who is the uk correspondent for france 24. what is the mood in france today? one of immense sadness and mourning. an extraordinary police officer who went above and beyond the call of

duty. substituting himself because this cowardly terrorist was using a woman ina this cowardly terrorist was using a woman in a supermarket as a human shield. it's a really shocking ordinariness of the scene that comes home from the pictures. when you see that supermarket with the trolleys lying around. france has been here before, the uk has been here before. are the same questions being asked all over again or have people stopped asking them? i don't think people will ever stop asking them. apart from the sadness and the shock, the biggest thing is the pride from fellow police officers, the army, ministers. notjust the defence or ministry of the interior. yes, there are serious questions to be asked. this was a petty criminal, 25 years old, originally moroccan and naturalised french. we should say his partner, an 18—year—old, is in

custody and being questioned. another friend of custody and being questioned. anotherfriend of his, 17 custody and being questioned. another friend of his, 17 years old, is being questioned. how did he get the weapon? since then, police have revealed there were some home—made bombs, there was a butcher's life. this man was intent on killing. he first hijacked a car, seriously killed one of the people in the kills, seriously wounded the other, still fighting for his life. attacked policemen who were jogging. —— killed one of the people and then seriously. into a supermarket. you could replace that with any sainsbury‘s or tesco and other brands are available. 50 people in that supermarket. one of them a retired police officer, he managed to get some people to safety. again, a story we had back in the november attacks in 2015, but people in a cold storage which locked from the inside. came face—to—face with the attacker. managed to flee and those are very important for all of the

training police... they made that up—to—date information. he told them what he was like, what weapons he had, etc. he shot this arnaud beltrame, this real hero. although that word is abused, in the neck and in the thorax. unfortunately, arnaud beltrame died early this morning. we heard this evening, he will have, after the french president emanuel macron, chaired a special meeting with the ministers of the interior and defence, a special national funeral. i think that is totally appropriate. the terrorist was on a register. for people who are known for having been radicalised but unfortunately the assessment was that he wasn't an imminent danger. what were these judgments? so difficult. we live in open democracies, they are difficult. to have the resources that are needed to stop an individual like this is tantamount

to impossible. there is the kind of police states we would want to live in? presumably, given the enormous courage of the police officers and arnaud beltrame, that, in a way, provides a unifying emotion of pride in grief that must put some of those questions at bay. beautifully put question, actually. ifi questions at bay. beautifully put question, actually. if i may, iwill read one of the tweets i find, apart from the one in french from theresa may yesterday, which means so much to french people and a lot of people. also the tweets you have read throughout the day on the bbc. i've been discovering along the day from british police officers. commanders, ordinary police officers, on the beat, knowing when they get called out, this may happen to them. this tweet from a french philosopher. "to all assassins in hiding who seek glory through violence, before you murder innocents and die as cretins, meditate today's lesson of heroic

arnaud beltrame. it is not by killing that one reaches martyrdom, it is by saving lives." on that thought, let's leave it. thank you for talking to us about this extraordinary story. we have to move on. investigators from the information commissioner's office, are assessing material seized during a seven hour search, of the london offices, of the company cambridge analytica. the high court had granted a warrant to access the company's data bases and servers. it's part of a larger investigation into the use of personal data in political campaigning. the former shadow northern ireland secretary, owen smith, says he'll continue to oppose labour's position on brexit. he's been sacked byjeremy corbyn from the front bench, for saying there should be a referendum on the terms of any final deal. mr smith believes the party leadership should be speaking out more forcefully about what he sees as the economic risks of leaving the eu. our political correspondent iain watson reports. the show of unity was relatively short lived.

owen smith failed to topple jeremy corbyn as labour leader in 2016 butjoined his shadow cabinet lastjune. he was sacked for being out of step on the eu, when he called for a second referendum on the final deal. it was a bit of a surprise, not least when other members of the shadow cabinet have said similar things and haven't been sacked. we need, at the end of this process, to trust the british people once more to make a final decision on whether they're content with the real terms of brexit. curiously, last november, the shadow cabinet member diane abbott told her constituents she'd argue for the right of the electorate to vote on a final deal. but she stayed at labour's top table. why did you sack him? so whenjeremy corbyn went to speak to party activists, i tried to get him to explain. why didn't you sack diane abbott? nice to see you. thank you so much, all of you, for coming. owen smith insists he was surprised to be sacked because he says his views are far more in touch with those of the party membership than his leader's.

and certainly in an academic survey of more than 4,000 labour party members last year suggested that three—quarters of them wanted a second referendum on the final deal with the eu. but most of the activists i spoke put tight—lipped loyalty ahead of any policy concerns. yes, i think we need unity to beat the tories. is he right to sack owen smith over europe? no. and it's perhaps a measure ofjeremy corbyn‘s grip on his party that he can sack someone with pro—eu views swiftly without causing a serious split. iain watson, bbc news, westminster. a car bomb has targeted the head of security in the egyptian city of alexandria. the minister survived, but two policemen were killed and five others were injured. the attack comes two days ahead of the presidential election. the headlines on bbc news: hundreds of thousands

of people take to the streets across the united states for mass demonstrations in support of gun control. france will organise a national tribute for the policeman who died after changing places with hostages during yesterday's terror attack at a supermarket. the labour mp owen smith sasteremy corbyn made a mistake by sacking him from the shadow cabinet for calling for another eu referendum. sport now and we have a full round up, from the bbc sport centre. australia's cameron bancroft is caught ball tampering with his captain, steve smith, admitting that he knew. he knew in advance. he was caught on camera during day three of the third test in cape town

using a piece of sticky tape to work on the ball, he then hit it inside of his trousers before being questioned by the on field umpire. both players apologise devon smith said he will not be resigning as captain. i'm not proud of what has happened. it's not within the spirit of the game. my integrity, the team's integrity, we spoke about it, we thought it was a possible way to get an advantage. and obviously it did not work, the umpires did not see it change the way the ball was behaving or anything like that. it was a poor choice. we are deeply regrettable, i guess, our actions. lewis hamilton is just lewis hamilton isjust getting better and better. he will start tomorrow's australian grand prix from pole position after producing a

lap he says was as close as he could get to perfection. formula 1 is back. it was excitable. we were supposed to be about to witness a challenge to lewis hamilton and his mazzetti's team dominance. ferrari looks like they might have close the gap in pre—season testing. when sebastian vettel took the time sheet in the second session it felt like things were about to get tasty. mercedes suffered another blow at the start of the second session. va ltteri bottas the start of the second session. valtteri bottas giving his mechanic a sleepless night. no such troubles for hamilton, the reigning champion clocked the quickest time ever seen in qualifying at albert park, the gap to the ferraris of kimi raikkonen and vettel was massive, more than half a second. for some, mate, nice forsome, mate, nice work. it was hamilton's fifth consecutive pole position down under, record six in australia, surpassing ayrton senna. it will take something remarkable to

stop him retaining his title. no premier league football today, busy weekend of international friendlies. they went behind to south korea but equalised through an own goal after a clever oliver norwood free kick. substitute and debutant paul smith scored the winner in the 86th minute. smith plays for queens park rangers only called into the squad on friday after playing for the under 21s against spain on thursday night. england's performance against the netherlands last night has been overshadowed by fan trouble in amsterdam. more than 100 fans were arrested. police were questioning why the match was scheduled on a friday night describing the behaviour of many travelling supporters as appalling. world cup preparations for england continue on tuesday afterjesse lingard's winner last night. they face italy at wembley. cambridge have won the

men's, women's and both reserve boat races. the first time that has happened for 21 years. the light blues took control from the off in the men's race and remains ahead to beat rivals oxford by three lengths taking their total victories in the famous race to 83—80 in their favour. similarly convincing in the women's race. cambridge finishing a full seven lengths clear. it is estimated at around 250,000 people watched on the banks of the thames. cambridge's women are now lead the overall standings 43—30. that is all the sport for now, more later. public health england has issued fresh precautionary advice to anyone in salisbury who may have come into contact with the nerve agent used to attack sergei skripal and his daughter yulia. the advice is relevant to as many as 500 people who may have visited the pub and pizza restaurant between the time of the poisoning and before they were closed the following night.

our correspondent kathryn stanczyszyn spent the day in salisbury. it's a busy saturday here in salisbury today, busier than the last couple of weekends, partly down to the free parking that the council announced to try and get people back into salisbury. they have said that businesses and shops have been suffering because people have been staying away following the poisoning. still a police cordon in place where i am at the park where sergei and yulia skripal were found slumped unconscious on sunday 11th march. now, a week later public health england issued advice to anyone who had been in either the zizzi restaurant that they had dined in that afternoon, or the bishops mill pub from the sunday afternoon to monday evening at closing time, saying anyone who had been in those locations needed to wash their clothes as a precaution because prolonged exposure or repeated exposure to any of the nerve agent used could be dangerous to help. of the nerve agent used could be dangerous to health.

they said it was very much precautionary but they were advising people to wash their positions and their clothes, unless they were dry clean only or as something that couldn't be or something that couldn't be washed in that way. then they were saying, bag them up, put them in plastic twice, double bag that and keep it safe somewhere. this latest advice yesterday from public health england again was talking about possessions, but it said if you've got those sort of dry clean only or other things that you haven't been able to wash bagged up please do contact wiltshire council who will then arrange to come and pick those possessions up to be destroyed. they haven't confirmed that, but that is very likely to be what they mean, because they are talking about compensation. they say you'll be paid for whatever those items are. people in salisbury have been telling me today that they are a bit concerned that this advice has now come out two weeks after that initial advice because if that was the case, why not tell people right then that those possessions were going to be picked up? but generally, most people going about their business as normal today and saying they're just trying to carry on life here. drivers are being dazzled

by the headlights on new cars, according to an rac survey. two thirds of motorists said they were caught by the glare of headlamps regularly and 15% claimed they had nearly crashed because the lights of oncoming cars were too bright. all headlamps on uk cars must conform to eu guidelines. earlier i spoke to rod dennis, spokesperson for the rac. this is actually in direct response to what our members and a lot of drivers are telling us. that's simply that a lot of car headlights these days are simply appearing to bright. we went out to a wide range of motorists right across the country to try and understand this a bit better. and sure enough the figures we are getting back which you quoted just there, suggest there is perhaps an issue. our understanding is because of the different types of light bulbs that are now used in cars, this is what is leading to a lot of them appearing brighter. these days, we use leds are a lot

more, fantastic if you are a driver, much better view of the road, much more energy efficient, much cheaper. they last much longer. so, as a driver and a vehicle manufacturer, fantastic. but what our research is showing is if you are on the receiving end of that in another vehicle, actually it can actually be quite a hazard potentially and really get in the way of you driving safely. well, yeah, because the majority of those affected are saying it takes them up to five seconds before they can see clearly again and a vehicle travelling at 60 miles an hour would cover 134 metres in that time. that's a lot of time in which to potentially have an accident while your eyes are closed off while are closed or while you are being dazzled. exactly. this is down to what leds actually do. they actually scatter the light across the back of the eye, and that means that while you can actually zone in on the led very clearly, it makes actually looking at anything else outside that led quite difficult. it's the same sort of thing if you look directly at an led, perhaps on the front of your fridge freezer, or microwave, or cooker or something like that and then look away, you will have that kind of imprint left on your eyes and it's that

that's basically been happening again and again when conditions are dark and drivers are driving at night. so, it's something that needs to be looked at and thankfully we have spoken to the government over the last couple of weeks and it does look like the issue is beginning to be taken seriously. it seems a bit slow to be only to be beginning to be taken seriously now. i mean, this is across the eu and all of this, you know, car safety equipment has to go through an immense amount of testing. why on earth has this been allowed to happen in the first place? well, everyone's different. this is the thing. so, different people do receive this sort of light differently. our research shows interestingly that actually across the age groups people are concerned about this as an issue. but manufacturers are very attuned to this, they put in place levelling technology, which is designed to actually allow leds to sort of dip clearly so that you're not affected by them if you are an oncoming driver. the issue comes from a range of factors. one is many of us are driving cars which sit much higher on the road, that means the direction of the headlight will be different if you are in a car like a hatchback which sits much lower on the road. also, the condition of our roads, we talked a lot about potholes

and pull condition roads, even adverse camber on the road, all of those things can affect that levelling technology and therefore can, if you are unfortunate enough, lead to those leds directly going into the back of the eye and that's what causes some of these problems. also, the condition of our roads, we talked a lot about potholes and poor condition roads, even adverse camber on the road, all of those things can affect that levelling technology and therefore can, if you are unfortunate enough, lead to those leds directly going into the back of the eye and that's what causes some of these problems. but it is being looked at and it is being taken seriously. it will sadly be probably years before we see any difference here because any changes that come in place need to be agreed and approved internationally and again at an eu level. but it is something that is being taken seriously and that is hopefully a cause for some hope for drivers that are concerned about it. cities across the world are turning their lights off for earth hour, an event coordinated by the world wide fund for nature to highlight the importance of preserving the environment. this was the scene in sydney, with the opera house plunged into darkness. ican i can still see some lights, there. where is the darkness? the lights were also switched off the sydney harbour bridge. hong kong was another

city taking part — the skyline turning almost completely black. that does look very unlike hong kong. my word! where's that? and at 8:30pm local time singapore counted down to their big switch—off. is that coming now? there you go. a few hours after that the lights went out in moscow's red square — saint basil's cathedral first to go. landmarks going dark across the uk tonight include buckingham palace, cardiff castle, and the kelpies in scotland. more pictures to come we hope. weather with matt taylor. fully lit. more will see the sunshine tomorrow. rain and drizzle the of central and central and southern and england

wales. clearing skies, mist and fog patches, showers for scotland and northern ireland, leading to some icy conditions especially as temperatures in many parts of scotland, northern ireland, northern england and wales dropped close to freezing. cold start. isolated shower in northern england and northern ireland. showers in the form of scotland, rain, sleet and snow. temperatures in the sunshine, double figures. warmer compared to this afternoon. clear skies in sunday night. frost into monday. a north atlantic air. rain by the end of the day in belfast and cardiff. this is bbc news — our latest headlines. hundreds of thousands of people join survivors
