evening and welcome to bbc news. hundreds of thousands of people have taken part in rallies across the united states demanding the white house and congress are tougher gun laws. the protest, called march for oui’ laws. the protest, called march for our lives, have been led by survivors of the massacre at a school in florida last month in which 17 people died. there were rallies in solidarity in the uk and in sydney and tokyo. schenken dc saw the biggest turnout for an anti—gun demonstration in 25 years with celebrities joining students and teachers who vowed to stop at nothing until lasting changes made —— washington. # run, run, run.#

this wasn't some run—of—the—mill saturday morning protest by a bunch of disaffected kids. this was way, way bigger than that. far more significant. what do you hope today will achieve? i hope that congress will actually do something about gun laws. stop ignoring us! we should not have guns in schools. like, donald trump is wrong for even trying to give teachers guns at all. and it wasn'tjust in washington. protests took place across the country, bringing the so—called apathetic don't—care generation onto the streets in unprecedented numbers. these children, tomorrow's voters, are determined that this should not be a one—off protest but in the national rifle association, they have an implacable opponent. it really is the irresistible force meeting the immovable object. # it ain't about how fast i get there. ..# the rally had performances by the likes of miley cyrus and ariana grande. # know that we're going to be alright.#

but the headliners were the young people. there was martin luther king's 9—year—old granddaughter, who had a vision of her own. i have a dream that enough is enough! cheering. and that this should be a gun—free world — period. and then, of course, there were the survivors from the marjory stoneman douglas school in florida. we will come together. we will get rid of these public servants that only serve the gun lobby. and we will save lives! we need to arm our teachers. we need to arm them with pencils, pens, paper and the money they need. they need that money! and finally, silence. alarm bleeps.

since the time that i came out here, it has been six minutes and 20 seconds. the shooter has ceased shooting and will soon abandon his rifle, blend in with the students as they escape and walk free for an hour before arrest. fight for your lives, before it's someone else'sjob. cherring. -- cheering. jennifer hudson brought the rally to an end, singing the times they are a changin‘ — and they may well be. after what these young people have been through, they're not intimidated by the nra, nor cowed by politicians. it won't be easy to change america's gun laws, but for the first time in a very long time, it no longer seems impossible. jon sopel, bbc news, washington. jupiter being paid around a while to

arnaud beltrame who was shot by islamist gunmen yesterday in the town of trebes in the south of france. three other people were killed and 16 injured. this attack has become not the story of a gunman 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. the official brexit campaign has been accused of breaking a little spending more stream eu referendum. a formal work on the campaign can perform claimed in interviews that the organisation breached official spending limit. emma watson is here with us. the. this is slightly complicated going through this but effectively, what has happened is the allegations are complicated, it

is straightforward, a vote leave volunteer has effectively said they cheated, they spend far more than they were allowed to do and found ways around the rules. of course this has been vehemently denied. the central allegation is a vote leave campaign was allowed to spend £7 million in the campaign, smaller groups that basically we are campaigning for the same calls were allowed to spend £700,000 but in addition to its own spending, it 7 million, leave also spent £600,000 toa million, leave also spent £600,000 to a young man named darren who was running a youth campaign and that is actually, according to the rules, perfectly legitimate, the long as his organisation is completely separate. the allegation is being made, this in effect wasn't an independent company, the allegation is it is effectively a front campaign and it is being alleged that all the money that went to believe had to then be spent on

digital advertising with the company that leave lieb —— used, the canadian company, and if true it would be a breach of the rules but all of the campaigners in leave at the time were saying this is untrue, it isa the time were saying this is untrue, it is a fabrication, darren grimes said it into anything wrong either and tonight we have a tweet from perhaps the most famous person in that campaign, boris johnson, perhaps the most famous person in that campaign, borisjohnson, saying it is ludicrous, leave won the referendum fair and square. thank you, ian. it will have a closer look at that during the newspaper review. now, let's look to other news. two policemen have been killed in a car bombing in the egyptian city of alexandria. but officials say the security was the target. his vehicle was passing by when the device went off. he escaped unharmed and five others were injured. the attack comes others were injured. the attack co m es two others were injured. the attack comes two days before the presidential election. sally nabil bentaleb said the scene of the attack in alexandria. this is the street where

the explosion took place. as you can see, the whole area is cordoned off and the scale of the damage is quite big, actually. many of the cars here are severely damaged. we understand that an improvised explosive device has been planted under one of the parked cars and it went off when the convoy of alexandria's security chief was passing by. the security chief survived, but we know there are victims among his police guards. the timing of the explosion is quite critical, actually. it comes two days or less before egyptians go to the polls to choose a new president. the minister of the interior was here a short while ago and he had a careful look at the place. the ministry of interior issued a statement as well saying the security chief is back to work and he will not be discouraged by the explosion.

we do not know yet who carried out this attack but we understand that the routes in and out of alexandria are being closely monitored by police forces. the ministry of interior have said that security forces are on high alert but what happened here on this street shows there are still some security loopholes. the commander of nato forces in afghanistan says russian influence is destabilising efforts to end the conflict. generaljohn nicholson's comments come as the us stepped up their support for afghan support the reform forces who they say are making progress. the patient corresponded just amrabat reports. f-16 f—16 fighter f—16fighterjets f—16 fighter jets to f—16fighterjets to turn to refuel high above afghanistan. geoff slater... they are ready to get back into the fight. providing air cover

of the sphere, it is theirjob to ta ke of the sphere, it is theirjob to take the fight to the caliban. demand is like these and special forces make up just 10% of afghan troops. but they carry out 80% of offensive operations. but, says the general, some of the taliban insurgence these troops will be fighting are likely to have been armed by rush. we have had stories written by the caliban that have appeared in the newspaper that they have provided support, but in sport at the headquarters and given to us by afg ha n at the headquarters and given to us by afghan leaders who said this was given by the russians to the taliban. translation: last month the president of afghanistan made an unprecedented peace offer with a wide ranging amnesty for taliban leaders whojoined the wide ranging amnesty for taliban leaders who joined the negotiations. there has been no response yet. the taliban has rejected the offers in the past and there is that foreign

meddling in afghanistan is likely to make any peace here even less likely. investigators from the information commissioner's office are assessing material seized during are assessing material seized during a seven—hour search of the london offices of the company cambridge analatica. they was all part of a large enquiry into the use of personal data and political campaigning. the headlines now on bbc news: huge rallies have been held across the united states to call for tougher controls on guns. frind says it will hold a national memorial service for the police officer who died after changing places with a hostage in the siege ata places with a hostage in the siege at a supermarket. the commander of nato forces in afghanistan claims russia is trying to stall effort to end the war with the taliban.

the advice is for 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. 0ur correspondent kathryn stanczyszyn spent the day in salisbury. it isa it is a busy saturday here in seoul is britain that. is there than the last couple of weekends, partly down to the free parking that the council announced, to try to get people back into salisbury. they said that businesses and shops have been suffering because people have been staying away following the poisoning. bpb scored in is still in place. —— the police caught and is still around the park wet sergei skripal and his daughter were found on sunday the 15th of march. police advised that anyone who died in the rest of that they don't in that afternoon all work in the pub,

anyone in those locations either to wash their as precaution, because prolonged or repeated exposure to any of the dotage and use could be dangerous to health. —— any of the nerve agent used. they said they should wash things in water unless they were dry clean only, in which case they would say back them up, but the plastic ties, and keep them safe somewhere. this latest advice yesterday from public of england was talk about possessions. but it said that if you have those dry clean only or other things that you have not been up to wash backed up, please contact the council, who will arrange to come and pick those possessions are up to be destroyed. they have not confirmed that, but thatis they have not confirmed that, but that is very likely to be what they mean, because they talk about compensation. they say that you will 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 the initial

advice. if that was the case, why not tell perborate then that advice. if that was the case, why not tell pertcféif the sickee; 77771— are f; 3 the fi—iififf -—e dadjust”"'l 'got ' ' ' luckier. —— dad just trying to go about m life here. a rescue operation to try and save a large group of whales, who became stranded on a beach in western australia has come to an end. all but five of the 150 short—finned pilot whales have died, despite the efforts of conservation officers at hamelin bay. it came nine years — to the day — after the last mass stranding at the same spot. phil mercer in sydney has the story for hours, dozens of volunteers supported by vets and wildlife officials tried to save survivors from a stranded pod of short finned pilot whales. about 150 were found at hamelin bay in western australia. most were dead by the time help arrived. but rescuers using heavy machinery did manage to return six animals into the water.

for us, the biggest concern is them being out of the water and sunburnt, so we've got them covered, and we're trying to keep them as moist as we can. one didn't survive, and there is a risk the others could return to dry land. it's not the first time there's been a mass beaching in this part of the western australian coast. but scientists don't know why some whales appear to be drawn as if by a magnet to the shore. researchers have called hamelin bay a whale trap. they believe the shallow waters and coastline can interfere with the bio acoustic sonar these graceful mammals use to navigate safely. there is a theory that intense wind and waves generated by cyclone marcus that's been battering parts of northern australia could have disrupted the whales‘ sensitive guidance system. the dna samples are being taken from the dead mammals to try to understand why so many ended up on the beach. work to remove their bodies is continuing.

a shark alert has also been issued by fisheries authorities in western australia, because of fears the whale carcasses may attract ocean predators. phil mercer, bbc news, sydney. 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 a direct response to what oui’ this is a direct response to what our members in four drivers are telling us. and that a lot of car headlights these days is simply appearing too bright too bright. we went out to a wide range of motorists around the country, and sure enough, things are going backwards. this suggests that 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 brighter. these days, we use led is a lot more. fantastic if you are driving, a better view of the road, much more efficient, cheaper, and last longer. —— leds. as a driver and manufacturer, fantastic. but if you are on the receiving end of that in another vehicle, it can be quite a hazard, potentially, and really get in the way of you destroyed to make driving safely. yes, it takes some people at visegrad four they can see clearly again. and the vehicle telemetry is 60 miles an hour would travel 134 metres in that time. that is a lot of time to potentially have an accident, while you are being dazzled. exactly. this is done to what leds do. they scatter light across the back of the eye. this means that why you concerning on the led brake firmly commit mixing anything outside that

quite difficult. it is the same thing as having an led on the front ofa thing as having an led on the front of a fridge freezer, microwave, or somewhere like that, if you look away, you have that imprint on your eyes. and that is what is happening when conditions are dark and drivers are driving at night. it is a limit is to be looked at. thankfully we have spoken to the government over the last few weeks, it to be —— and it looks like it is studying to be taken to sea. this is across the eu, and all of this car safety equipment has to go through as a mass of testing. why has this been allowed to happen in the first place? everyone's different. different people to receive this sort of light differently. 0ur people to receive this sort of light differently. our research shows that gci’oss differently. our research shows that across the age group, people are concerned about this is an issue. but manufacturers are atjune to this. they put in place levelling technology that is designed to allow leds to dip clearly so that you are not affected by them if you are an

oncoming driver. the issue comes from a range of factors. many of us are now driving cars that set much higher on the road. that is the direction of the headbutt will be different if you are a car like a hatchback that is lower on the road. and the condition of our roads. we talked about potholes and poor roads, even adverse points in a row. they can unfortunately did leds go direct into the back of the eyes, causing the problem. this be looked at and take in syriza. it will sadly be probably use it will we see any difference here. this is because these need to be agreed and approved internationally, here and at an eu level. but this is being taken seriously. time for the weather. thank you very much. had to say, but added that winter is done with us yet. but as we go through tonight, that hop
