the us general manager of tiktok has said the chinese—owned video—sharing app is "here for the long run", after president donald trump said he would ban it in the us. vanessa pappas told tiktok users in a video statement that its staff were building "the safest app" amid us concerns about data protection. tiktok is mostly used to share short videos, usually about 15 seconds long. and it has grown rapidly in the last year, now boasting more than 800 million active monthly users worldwide. but it's owned by a chinese company, bytedance, and it's this last fact that concerns the us security forces. there is in fact a precedent for this us announcement. india has already blocked the app, and australia is also considering a ban. here's our technology

reporter chris fox. well, the app has been decompiled by security researchers. they've looked deep into it, and as yet, they haven't found a smoking gun. there's nothing obvious in the app that seems to be sending information back to the chinese. but as with any chinese company, they can be compelled to give information to the chinese security services, and any app on your phone can gather lots of data while it's there. even american apps like facebook do this. they can scoop up your location data, your contacts and things like that. and they store that on servers outside of china, so tiktok is run as its own entity outside of china. they run it as a separate business. and they said they store the data outside of china, so it's not subject to chinese jurisdiction. but i think the fear is that with all that information about american and other consumers that they store our servers, could potentially that find its way back to the chinese security services and then put information at risk? that's the concern. and what have tiktok

said in response? tiktok has said it does not give any information to the chinese government. tiktok itself isn't operated in china. they have a different version of the app called douyin. and they've said that they are planning to stay in america, in the us for the long run. they don't have any intention of closing down. there had been some rumours swirling that it might be bought out by another company like microsoft, but at the moment, that hasn't been confirmed. let's get more on this with dominic vogel, chief strategist at cybersc, a cyber security firm. hejoins me now from vancouver. thank you forjoining us here on bbc news. let me start by asking you what is in particular that worries president trump and indeed some other countries about tiktok and the way it works?” other countries about tiktok and the way it works? i think there are two questions. what worries president trump, i think he is living in its own

separate world. he is grandstanding and not quite worried about security applications. with tiktok and certainly other apps there is private —— privacy concerns about where the data is going and those are very valid questions. but how donald trump is going about doing it is pretty foolish in my opinion. and if he were to band tiktok in america, how would that work? how would he do it? that's the thing. he would not be able to do it. unlike china or iran with her only one or two internet service providers, and the us it is difficult to do that because there are so many telecom service provider so even many telecom service provider so even if you convince them to be able to do that, there will be able to do that, there will bea be able to do that, there will be a lot of loopholes and in all likelihood very close to impossible to successfully do that. what do you think it is that. what do you think it is that makes other countries so worried about tiktok then? there is always the spectre of china. that's what this great concern is all about and all very valid concerns and there

needs to be the right level of dialogue about doing that by taking these grandstanding events here like outright banning something without having sufficient dialogue, again that isjust having sufficient dialogue, again that is just donald trump being donald trump. it will have not done very well amongst the millions of young users in america if this does go ahead? i really think it is an active of him and looking foolish. even in the tech community, companies like apple and google, i don't think they will ta ke google, i don't think they will take it lightly as well. the tech community, there will be a big uproar about this and i think he isjust big uproar about this and i think he is just further distancing himself from the great people in america who are going to ultimately vote him out. another active foolishness. do you think he's taking some of tiktok‘s actions in the past personally?” taking some of tiktok‘s actions in the past personally? i think so. in the past personally? i think so. he has a beef with the chinese government and he thinks there is a connection with the government so he will do this asjust with the government so he will do this as just a boy of what he thinks is a bully tactic.

but if you dig beneath the roots there and see that really, i think it comes down to having greater dialogue around security and privacy discussions, all very valid concerns but again how he is doing it is entirely inappropriate. and what more do we know about the company byte da nce ? we know about the company bytedance? interesting because the parent company as microsoft was in talks to purchase the us operations and take that off of byte da nce operations and take that off of bytedance and try and at least make it more palatable for president trump in the us. that organisation bytedance, not too much is known about them other than the fact that they have said time and time again that they are not affiliate with the chinese government. 0k, good to have you on, thank you so much. thank you so much, appreciate it. several european governments have expressed concern about the resurgence of the coronavirus cases in a number of countries, including belgium and france, where numbers appear

to be heading upwards. spain, in particular, is struggling with a surge of new infections that has sparked european travel warnings, most notably from the uk. in france, the seven—day average of new infections passed 1000 per day this week for the first time since the first half of may. rates of infection in germany remain low, but health officials there have expressed "great concern" over an uptick in cases in the country. 0ur correspondent nick beake has more. i think spain's an interesting place to start because there has been an increase in cases. it's not at the level that it was, say, three months ago when so much of mainland europe was plunged into this crisis at the darkest point. but the cases have risen tenfold in spain compared to six weeks ago, when they'd done quite a lot to bring the level down. and what we're seeing in spain and other parts of mainland europe are not cases spread out far and wide across countries, but particular clusters. so, it's aragon and catalonia in spain, they're the two

regions most affected in the north—east of the country. and what we are seeing are different countries taking different methods to try to stem the individual rises in their country. so, in belgium, for example, where i'm talking to you from this morning, they've seen cases go up by 70% over the past week or so. and that's led people in antwerp, where more than half of the new cases have been — in the province of antwerp, there's a big city there, but also the province — they've brought in an overnight curfew for the first time since the second world war. so, that gives an indication of the extent to which some authorities say they need to go all out to try and tackle the virus. two of the uk government's scientific advisers have each warned that pubs and other leisure facilites may have to close once schools reopen in england next month to prevent a sharp rise in coronavirus cases. the experts say a possible trade—off may be needed so pupils can return

to the classroom. here's our science correspondent victoria gill. a family celebration tinged with the impacts of the pandemic. while a downsized wedding went ahead in bradford, new restrictions here and across a swathe of northern england mean that friends and families in different households are once again being told to keep apart. it's a weekend of mixed messages. planned relaxation of lockdown restrictions in england has been put on pause, but outside of areas where restrictions have been tightened, people who've been shielding since march have been advised that it's finally safe to go out. for michelle in leicester, who's been treated for breast cancer, this meant an emotional reunion with her mum. the flowers are in the back of the car, you can just about see them. i'm only coming for the day. i'm not staying overnight, so i'm taking no extra risks. i'm just coming to see my mum. now, then, pixie! oh, yeah, look at that. whoo!

we made it! i know! i've got a present for you. oh, wow! but it's a nervous time for both of them. they're beautiful! i'm not right sure whether shielding is over, because in a holiday town like we are, we get too many visitors to feel safe. the recent rise in infection rates linked to people in different households socialising together showed how close some communities are to a surge in coronavirus cases. while new restrictions in some areas are intended to pull them back from that tipping point, two of the government's scientific advisers, speaking to the bbc in an independent capacity, said that to fulfil the ambition to reopen schools, pubs and restaurants may once again have to close. closing some of the other networks, some of the other activities, may well be required to enable us to open schools. so, it may come down to a question about, you know, which do you trade off against each other?

and then that's a matter of prioritising, you know, do we think that pubs are more important than schools? so, what do you envisage will have to happen with restrictions later in the year? well, we'll probably start to see a second wave. we'll also see the usual seasonal influenza starting. i think some hard decisions will be made about what restrictions need to be reintroduced and whether that's potentially pubs and the hospitality sector taking a hit, in preference to education, but it will be a political decision. until there's a vaccine, even on the most special of occasions, this balancing act will have to continue. trying to keep life going while keeping the virus at bay. victoria gill, bbc news. robert west is a professor of health psychology and a member of the government's advisory group on behavioural science. he says england needs a reset on its pandemic strategy. we have seen in different countries in europe and different parts of the uk is a

different parts of the uk is a different strategies lead to different strategies lead to different outcomes. and if you compare what the strategy appears to be in england say versus scotland, then you do see a difference and it will make a difference. so scotland is essentially going for covid—i9 zero which is what independent sage are calling for. that is not absolute zero but what it does mean is you do everything you can in the short term to drive the infection rate down so the way you do get outbreaks, you can stamp on them quickly with effective test, trace, isolate and support system. but the key is to get it at a rate that people that you can open things up and businesses can open it with confidence and reasonable confidence and reasonable confidence that they are not going to be closed down again what we have at the moment u nfortu nately what we have at the moment unfortunately in england is more of a sort of yoga strategy which has been sometimes called this rather unkindly back a mould strategy. but the problem with this is because you're are

value, the famous r value, if you keep it hovering around one in many parts of the country, as we are doing, than it does not take much for it to go above that and for us to have to go into these more extreme lockdown conditions or restrictions in a way that makes it really hard for businesses and i feel for them actually because it's awful. they either expect to be able to open up and they find they ca nt to open up and they find they cant or they have opened up and now they are thinking we may have to close down again. let's get some of the day's other news. thousands of people have taken to the streets in germanys capital, berlin, to protest against the country's coronavirus restrictions. demonstrators say the measures, including wearing face masks, violate their rights and freedoms. germany has been less badly affected by the pandemic than other european countries, but cases are starting to rise again. unemployment benefits brought in to support americans who've lost their jobs during the coronavirus pandemic have expired, with congress unable to reach consensus on a new relief package. it means payments of $600

a week to millions of people ended overnight. the top democrats in congress have now resumed talks with the white house to try to reach an extension deal. there's an increasing number of new coronavirus cases in tokyo. 472 were confirmed on saturday, the second day in a row that the number of cases in japan's capital rose by more than 400. tokyo's governor has warned that the city could declare its own state of emergency, but the central government says there is still no need to do that. a former british government minister and current conservative mp is reported to have been arrested after he was accused of rape, sexual assault and coercive control. scotland yard say a man was taken into custody at a police station in east london on saturday and has been released on bail. the conservative party said it "takes all allegations of this

nature extremely seriously". the allegations against the conservative mp appear in the sunday times newspaper. the headlines on bbc news — president trump says he'll ban tiktok, the chinese—owned video—sharing app, in the us, calling it a threat to americans. across europe, several governments express concern about a resurgence in the number of coronavirus cases. classified documents from inside the british military raise fresh questions as to whether uk special forces in afghanistan may have tried to cover up the killing of civilians. the previously secret material was disclosed as part of a court case following a panorama investigation last year, which highlighed allegations that british forces had a policy of deliberately killing fighting—aged males even when they didn't pose a threat. the ministry of defence has denied such a policy existed.

0ur defence correspondent jonathan beale reports. this is how elite troops target the taliban — controversial night raids with the aim to kill or capture enemy fighters. this shows afghan commandos on a mission with american support. but it was the same tactics used by british special forces during their time in helmand. last year, bbc panorama heard allegations the sas had killed unarmed civilians, with testimony from survivors of a raid in 2011 who said the british shot family members when they posed no threat. we've blurred their faces to protect their identity. translation: they tied his hands in front of me. if you've tied someone's hands, how can they fight? lawyers representing one of the afghan families are now challenging the ministry of defence here at the high court. they're trying to find out whether there was a proper

investigation or whether there might have been a cover—up. and they've just forced the mod to release these highly sensitive documents, which show that there were serious concerns about the raid within the british military. in heavily redacted e—mails sent soon after the raid, one british officer asks... another soldier replies with reports that two of the afghans were shot reaching for weapons. he says... while another e—mail highlights the anger of an afghan officer, who suggests... 0ne mp says the documents warrant a fresh investigation. it's deeply alarming, it's deeply serious and the government needs to come clean. if that doesn't merit some kind of inquiry, because at the end of the day,

you're talking about war crimes, potential war crimes, then i don't know what does. the british military‘s own report into the raid, released to the court, says the four men killed were all armed and that one was a known taliban commander who'd been targeting coalition forces. in a statement, the mod said... the mod recently closed down the unit investigating allegations of potential war crimes in afghanistan. but these documents, at the very least, highlight concerns about its transparency and the secrecy surrounding britain's special forces. jonathan beale, bbc news. sri lankans are heading to the polls on wednesday in an election that will have far—ranging impacts on sri lanka's politics, rule of law and foreign policy. the election has been delayed
