0ur political correspondent, eleanor garnier, reports. six months ago, the health secretary, jeremy hunt, challenged social media firms like facebook, snapchat and twitter to work with the government to improve the mental health and well—being of young people. he wants action to cut underage use, encourage healthy amounts of screen time and moves to reduce cyber bullying. but writing in the sunday times, mr hunt says the overall response from the social media companies has so far been extremely limited. now he's warned that legislation could be an option and that the government will not be deterred from taking action to get the changes it wants. and mr hunt says the chief medical officer will investigate the impact of technology on mental health in young people, with the possibility of recommending healthy screen—time limits.

earlier, i spoke to sonia livingstone, professor of social psychology at the london school of economics, who researches the risks to children online. well, children are now beginning to use social media in britain from the age of about nine or ten. and by 11 or12, age of about nine or ten. and by 11 or 12, about half of them have their own profile. and of course, by teenage, they are pretty much all on it. so it depends on the age, but it is pretty widespread phenomenon. and obviously, they feel there are a lot of positive experiences from social media, but from your point of view and your research, what some of the negative and the downsides of children as young as that using social media? children as young as that using social media ? well, children as young as that using social media? well, i think what the research shows is that the risks are quite varied and quite diverse. but

of course, people are worried about it, young people themselves are worried about cyber bullying, they are worried about the kind of amount of hate and hostility and what we might call reputation damage that they see and that some of them and counter on social media. there is a lot of worry about pornography. so there is a range of risks but at the same time, as you say, the benefits are same time, as you say, the benefits a re really same time, as you say, the benefits are really great. so young people don't want to log off and turn away from it completely. but they and their parents, research also shows, really would like be differently managed and better supported from the social media companies. and do you think that is a real established correlation between the use of social media by very young children and mental health problems? we can't say that yet. we haven't got enough research and the research has not followed children and young people

of enough time. i think what we could be clear about is that social media are part of a mix and there are many pressures and difficulties that are affecting young people's mental health and their confidence in the world, and what social media does is, it kind of amplifiers and extends the risk and the sense of social pressure. at ages where children have not necessarily yet developed the confidence in their own norms, 01’ developed the confidence in their own norms, or the capacity to kind of push back against those pressures . of push back against those pressures. so it is in some ways too young, though still research shows many children of figuring this out and finding ways to be resilient. 0ur political correspondent, nick eardleyjoins me now. exactly what the government saying on this? mr hunt still wants social media companies to come forward with

something. ideally, the government wa nts a something. ideally, the government wants a voluntary approach where the tech companies and social media companies, together and say, here are some of the solutions to the big problems you have. highlighted. but at the same time, he says, if you don't do that and you have not done that so far, we will act regardless. that is why he is talking about legislation, potentially introducing new laws to govern is. what we don't have specifics about exactly what those laws might look like, how they would operate and enforce the rules that the government wants to introduce. part of the reason for that, quite frankly, is because it is not a simple thing to do. mr hunt acknowledges that in the letter he sent to these companies today, saying, you guys have lots of money, you have some big brains, work it out for yourselves. but if you don't, we will do it anyway. so they have had the letter, have we had a response yet? we have heard from

google, saying that they understand these challenges of keeping young people safe online. sharing the commitment to that and highlighting some of the schemes they have introduced. family link, which they say helps parents set digital ground rules and limits screen time, something mr hunt has highlighted as a problem. they also say, we have got this online safety security course which has been taught to 40,000 schoolchildren so far. but clearly for the health secretary this morning, there is a feeling that that has not gone far enough yet. that is why he wants a further review of the impact on this and mental health and is introducing the idea of further action. thank you very much indeed. the government is to increase the powers available to police and the security services to try and stop terror attacks at an early stage of planning. a document leaked to the sunday times suggests counter

terrorism officers will target up to 20,000 lower priority suspects. our home affairs correspondent, tom symonds, reports. the murderers behind last year's atrocities in britain. men who planned to kill innocent people. yet only three were on mis‘s radar in any way before striking, and only one of those was being actively investigated. better intelligence, at an earlier stage, might have stopped some of this happening. today's leaked report suggests counter—terrorism investigators could more widely share information on up to 20,000 lower priority suspects with various authorities, in the hope of receiving earlier intelligence of risky behaviour, such as planning an attack. the government has already promised more staff for security agencies like m15 — crucial if they are to target a greater number of suspects. and new powers have been promised — again, these are expected to focus

on allowing police to move in at an earlier stage when attack planning is less well advanced. already announced are higher sentences for viewing terrorism content online, or publishing information about the police or the military for use in targeting attacks. the home office would not comment on these leaked reports, but said the coming strategy would be a comprehensive response to the evolving threat from domestic and international terrorism. tom symonds, bbc news. at least 31 people have been killed and 50 injured in a suicide bomb attack in the afghan capital, kabul, according to officials. the bomber targeted people waiting outside a voter registration centre. it's the latest in a string of attacks in afghanistan since voter registration began this month, ahead of elections in october. election officials say security is a big concern, as the taliban and other militant groups either control or contest large areas.

two weeks after the suspected chemical attack in syria, international experts have finally carried out an inspection in the former rebel—held town of douma. the organisation for the prohibition of chemical weapons said its inspectors had gathered samples, which would be examined in specially—designated laboratories. andrew plant reports. it's now two weeks since these scenes played out on screens around the world. released by the syrian opposition, a video appearing to show the aftermath of a chemical attack. the allegation that chlorine had been used met with international condemnation. a team of experts from the organisation for the prohibition of chemical weapons arrived in damascus earlier this week, but their attempts to reach the site in douma were thwarted when the security team came under fire, leading to a three—day delay.

experts say if chlorine was used, that timescale could make it hard to detect. if it was a chlorine bomb attack, it is harder to have any evidence at this point in time, two weeks after. chlorine evaporates very quickly and does not remain in the bodies or the soil. so it will be difficult to find conclusive proof that it was a chlorine attack. america's defence secretary has accused the syrian government of orchestrating the delays while it cleaned up the area. it's now a week since the us, uk and france launched air strikes in syria against, they said, chemical weapons depots and production facilities. syria and its ally, russia, has denied any attack took place. experts will send their samples for analysis to see what, if anything, can still be detected on the ground. verne troyer, who is best

known for playing mini—me in the austin powers films, has died at the age of 49. the actor has been ill recently and had a history of problems with depression and alcohol. simon clemison reports. he is exactly like you in every way... except one—eighth your size. but that never held back mini—me... i shall call him... 0r verne troyer. mini—me. screams the role of dr evil‘s smaller clone in the austin powers comedies brought him worldwide recognition. but his credits also include harry potter and men in black. hi! i'm verne troyer! more recently, verne troyer has been over here, entering the celebrity big brother house in 2009. i'm going to play the nice guy but, you know, deep down,

i'm going to be evil! he cackles earlier this month, the actor was again admitted to hospital in los angeles, as he battled with alcohol addiction. statements on his social media accounts highlighted struggles and also the issue of depression, but it's not clear exactly what has led to his death. # it's a hard knock life for us... yeah! verne troyer said his part in austin powers grew as they saw what he could do. tributes have been led by its co—creator and the man he starred alongside. mike myers said troyer was the consummate professional and a beacon of positivity. simon clemison, bbc news. tributes have been coming in to the late actor from stars of the screen and the sporting world. his beloved american football club, the pittsburgh steelers, tweeted: "our thoughts and prayers are with the family of verne troyer." meanwhile, the oscar—winning west wing actress marlee matlin said: "so sad to read of the passing of verne troyer.

britain quits the single market and the customs union after brexit. and now, the business select committee of cross—party mps says the uk should think again. it said that removing tariffs on imported food could have extremely damaging consequences for british farming, and crashing out of the eu without a deal would be disastrous for the sector. it says remaining in a customs union would be the best for the food—and—drink sector. no manufacturer we saw wanted to have different rules and regulations governing the way in which they must do business in the uk, compared with the rest of the european union. they want close regulatory alignment between the united kingdom and the european union after brexit, and also, we don't want customs checks and delays. food and drink are perishable goods. we don't want then sitting at ports. the government said that leaving the eu gave the uk a golden opportunity to secure ambitious free trade deals, while supporting

our farmers and food and drink producers. some of those producers might disagree. one of the favourites to be the next first minister of wales has said he will seriously consider throwing his hat in the ring. mark dra keford, wales's finance secretary, said he would consult his family before making a final decision. it follows the announcement by the welsh labour leader carwynjones that he would stand down in the autumn. runners in the london marathon have received a royal send—off this morning. the queen pressed the starter button from windsor castle, to celebrate the 110th anniversary of the first modern 0lympic marathon, started by her grandmother, also from windsor, in 1908. a record—breaking 41,000 runners have crossed the start line

for this year's race, set to be one of the hottest ever. the met office has predicted temperatures of up to 23 degrees celsius and people who are planning to wear costumes have been asked to make sure they're appropriate for the weather. 0ur correspondent, kate grey, is at the finish line on the mall for us now. it is really hot out there. very difficult conditions for all the runners. yes, it is heating up at the finish line, it is quite a tunnel so that is not a lot of breeze. we have seen the wheelchair athletes finish their race and i will get to that in a moment, but temperatures vary with areas of shade, but they are making sure there is enough water. elite athletes have taken advantage of the water stocks. earlier today, we did see david weir winning his eighth

title at the london marathon. he loves competing here in front of the home crowd and he did it in style with a sprint finish to the end, and this is what he had to say when i caught up with him at the end of the race. it is just caught up with him at the end of the race. it isjust nice to be back on the streets of london and get —— i got time out last year to recharge the batteries mentally more than physically. and i have just really enjoyed being back. training and racing. yes, so it is great to be back. to be honest, i did not know how the performance would go because the amount of time out i had last summer, but it has storm eva of good. you have now finished from the track and all your energy goes into the race, due think that is why you are feeling so reducing eight two to raise even more? i think so, it gets. even leading up to all the mountains i have done, when i was doing the track, it was always in the back my mind, next week, i have to go back on track and go to this race and get this qualifying time. and now you can pioli but all your

energy into one race, sorry, one distance, the marathon distance. —— you can put all your energy. he loves it here, he did not struggle too much with the heat but he did warn everybody should take advantage of the water. the women's race finished earlier and that saw madison rosario beat tower chair mcfadden from america. she was the favourite. to rosario also won gold at the commonwealth games so clearly over the moon at the end of that race. mo farah at the moment is still in the leading pack, still quite a distance to go. but we have heard from steve cram it has been brilliant performance so far and he is pacing it right and it will be interesting to see as the race continues whether he can keep that pace. it is a very tough field with

three of the best marathon runners. hopefully, this london crowd will keep him going and he will finish this race positive with his performance. and within the women's race, there was a lot of pressure to beat paula radcliffe's world record. but the leader was overtaken. quite a surprising leader, but showing that it a surprising leader, but showing thatitis a surprising leader, but showing that it is tough conditions out there and it could go anyway. but brilliant result for david weir to win his eighth title and plenty of racing to come in london. amazing result from him, thank you very much. sport now. and a full round—up, from the bbc sport centre. johanna konta want to give great britain 82—1 lead. great britain a 2—1 lead.

in the west of scotland. it's the first time they've been seen in the upper part of the river clyde for many years. i've been speaking to david nairn, from the clyde porpoise marine mammal project, and asked him why he thought they were there. looking for food, i would looking forfood, i would imagine. clyde is full of porpoises and the prey items for these animals. and how unusual is it to see them there? for this group, this is a transient group, we believe, that are more commonly seen in shetland and the 0rkneys and over towards north of rational way. we have a group of residents killer whales but usually within a west coast of scotland. it is quite rare that we have got this transient group making it the upper reaches of the clyde. tell us a bit about. they are extraordinary

creatures. we are seeing pictures of them now in the clyde. wonderful creatures. yes, they are super intelligent animals. top predators around the west coast of scotland. so we think we have got four or five females and a male and a definite sign so far. so it looks like... where would they normally be? we we re where would they normally be? we were saying how unusual it is for them to be in the clyde, where would they normally be seen? these transient groups, they kind of rome large areas and they can be seen offshore. not sure if it is this particular group, but normally to shetland, towards iceland and norway. so it is great as they are all the way down here. yes, bizarre

but wonderful. lovely to see them there in rather blue looking waters. absolutely fantastic! the clyde is a recovering environment and it is great news for the area and the people that live around the place. let's get a look at the weather. the upper reaches of the cloud looking like the mediterranean, blue skies. hours are looking for the rest of the country? not like that, i had to be sure you! that was recorded a little while ago. we are now looking at very much wetter conditions and the radar tells the tale. it is notjust the cloud, all over the western side of scotland, the weather front is gradually tumbling across northern and western parts of england and wales. and that feature geyser a depth of the south. the blue that you see is the storms which could be triggered by the heat, 23 or 24.

though the north and west, it is that little bit cooler and that is because the rain hangs around across the western side of scotland and becomes more showery, too late in the day, and the cooler regime behind that weather front, we are looking at around seven, eight, 9 degrees. that is how we start the new week, with bright weather at least for a time and then the rain from the west. this is bbc news. our latest headlines: social media companies are threatened with new laws by the health secretary if they don't do more to protect children online. he's accused them of "turning a blind eye" to the problems arising from social media use.
