this is bbc news, with the latest headlines for viewers in the uk and around the world. a warning for scientists working

on a covid vaccine — russian spies are trying to steal your work. at a time where the world is coming together, we're all trying to find a vaccine that both our people and people around the world can benefit from. to have the russian government engaged in that endeavour i think needs calling out, and i think the world should know it. a british schoolgirl who ran off to join the islamic state group, wins a legal battle to return home to fight to retain her citizenship. as temperatures rise around the world, a warning from scientists about the dangers of heat stress for the human body. and another grim coronavirus milestone: brazil confirms the number of infections has passed the two million mark, as the president tests positive again. hello, and welcome if you're

watching in the uk or around the world. do stay with us for the latest news and analysis from here and across the globe. i'm rajini vaidyanathan. britain, the us, and canada have jointly accused russian hackers of trying to steal information from labs trying to make a coronavirus vaccine. britain is also accusing russian "actors" of trying to interfere in last year's general election. russia has denied all the claims. our security correspondent gordon corera has more. today, the government lashed out at russia's spies, accusing them directly of trying to steal vital uk research on the coronavirus pandemic. given that the world is trying to come together to find a vaccine for our own people, british people in the uk, but also for people around the world, i'm afraid it's pretty egregious behaviour and it deserves and it should be called out in the way we're doing today. oxford university has been leading the world in developing a vaccine. i understand it's one of the labs whose computer systems have been

targeted. british intelligence says it's seen hackers trying to steal data from universities, labs and pharmaceutical companies. but its cyber security chief told me it's been trying to defend them. we're working flat out to protect vaccine research because it's so important to the nation right now. with our canadian and american partners, we've seen russian spies, who go by the name of cozy bear and the dukes, try to hack into the networks, undertaking some of our vital research. so, we've been able to detect it. this was russian tv news last night, saying their vaccine, developed jointly with the defence ministry, was nearly ready. the british government is not saying it has confirmation that the russians have actually obtained sensitive data. trials here are under way and it is clear, though, that many countries are racing to find a vaccine, both for national prestige and to avoid being reliant on others when it's ready. these cyber attacks on labs are said

to have been carried out by a group called cozy bear, part of the russian intelligence services. but today, we learned about another operation allegedly linked to russia. this one involved a more shadowy group called secondary infektion, whose exact identity is less clear. it's alleged to have spread information online to interfere with last year's general election. applause. during the campaign, labour presented a leaked document, arguing it showed the nhs was on the table in us—uk trade talks, but today, the government said it believed that the russian group was involved in spreading the document. the russian foreign ministry today mocked the allegations as confusing and contradictory, but russia has been long accused of trying to meddle, and according to the analyst who uncovered secondary infektion‘s work, the group's aim has been to sow division. it's the kind of thing where you can

see they're trying to drive wedges between different countries which are critical of the kremlin. and it's interesting that when they did the initial leaks of the trade documents themselves, they didn't actually focus on the nhs. the way they presented the leaks was much more, here's another case of the americans bullying the british. mr corbyn, do you have anything to say about russian disruption? in a statement today, jeremy corbyn said the claim was an attempt to divert attention from a long—overdue parliamentary report on russia expected next week. today's claims are a reminder that even during a global health crisis, hackers and spies remain active, and also that tensions between russia and the uk have not gone away. gordon corera, bbc news. on the line now from ottawa — dave masson, from the cyber—security firm darktrace. it's very good to have you with us, dave. you've written the us and canada where you are

accusing russian hackers of trying to steal information. how would they have come to these claims? you work in this field, how would they have drawn that conclusion? they've obviously amassed a lot of intelligence and evidence over a period of time since covid—19 first broke out that's now become serious enough for them to actually combine together this unprecedented statement. it's very unusual for any nation state to point the finger at another one. the prime minister wouldn't do so about a month ago when he spoke... but canada, the uk and the usa have felt that what's going on and the damage that may well been done was so serious that they had to come out and make this very public global statement. in that report we saw from our correspondent gordon, he talked about who these hacking groups might be. he talked about cosy bear and secondary infektion as some of them.

they sound like cuddly names, but they certainly don't sound like they are cuddly and what they are doing. what do you know about these groups? there's another one called fancy bear, they are tied to the g argue, the intelligence service. they actually said that apt29, also known as the dukes, are working with the russian intelligence services. it is their boldest term to wipe out... so you're saying this goes right to the heart of the kremlin? it goes right to the heart of what drives russia's national interests. they consider these attacks to be in their national interest, and in this case, the usa and canada into covid—i9 research. i was reading that canada had warned that by medical facilities could be vulnerable a few

months ago. can you tell us more about that? back in march our equivalent of the ncsc warned canada that there was potential for attacks on biomedical research into covid—i9. that has come to light, we've had biomedical research data attacked, we've had universities given grants to carry out research on covid—i9, so the warning has turned out to be true. dave, thank you very much. also here in the uk, the court of appeal has ruled that one of three london schoolgirls who ran away to join the islamic state group at the age of 15 should be allowed to come back to the uk to challenge a decision to strip her of her british nationality. shamima begum, who's now 20, is unable to leave syria after her citizenship was revoked last year. the case has provoked a lot of discussion here in the uk about how to deal with britons who chose to support is. anthony glees is professor of security and intelligence studies at the

university of buckingham. he discussed the decision with dal babu, a former chief superintendent of the metropolitan police, who acted as an intermediary between the begum family and counter terror police. i was brought in as an intermediary to try to build a relationship between the families and the police. because the families discovered that the authorities were aware that these girls were being groomed. in fact, girls from the school — one girl had gone, another girl was taken off the plane — attempted to go. even at that point, the authorities had decided not to inform the families. now the families were very angry because they felt if they had been told what was happening, then they could have stopped the girls going. so i think we need to look at this in the whole of 15—year—old children who are being groomed on the internet by passing theirfamilies. and remember, these are 15—year—old children. they turned up in syria, a war—torn country —

no sane person would ever consider going there. and within days, they were married off to men almost twice their own age. it was sexual abuse, it was abuse of young children. two of the girls we believe have died, and shamima begum is the only surviving one. she has lost three children, and we also have not had a serious case review. normally when there is a failure in safeguarding, the local authority would have a serious case review. she has had one appeal, which she lost unanimously. the first tribunal said that the home secretary was entirely entitled to strip her of her british citizenship in order to prevent her from coming back to the united kingdom — either because she was a danger to herself, or because she could be an iconic figure to other people in the united kingdom. and when, last year, she was interviewed by the bbc and others, they all found that she expressed absolutely no contrition for what she had

done, no contrition for supporting a regime that enslaved yazidi women, that carried out beheadings — jihadi john carried out at least four beheadings himself. utter brutality. it was her choice to do it, there's no sign that she feels what she did was in any way wrong, and i think many british people will not only have sympathy for priti patel's wish to keep her out of the united kingdom, but will actually think that this woman who went off to support a regime who wished to destroy all the values that make britain, the united kingdom the country that is — she went off to fight for a regime that opposed each and every one of these values. she now comes throwing herself on the mercy of british taxpayers

and british courts — that she herself reviled — in order to get back to the united kingdom. the reality of the situation is that we have responsibilities to safeguard children. it doesn't matter what colour they are or what their identity — if they are born in this country, we have that responsibility. and we should take that responsibility. we can't dump our problems on other people. and there is a danger if these individuals are not dealt with appropriately — and if it means arrest, that it will be arrest for this individual — then what happens is they live dangerously and it makes the whole world more unsafe. let's get some of the day's other news... in the united states, the fbi has begun an investigation into the hacking of high profile twitter accounts, as part of an apparent bitcoin scam. among its victims were elon musk, barack obama, kanye west, and bill gates. twitter said the attack took place after employees with access to internal systems were successfully targeted. the flood fighting effort has

continued in southern china. soldiers are racing against time to reinforce river banks with sandbags while residents flee high risk zones. since the flood season began injune, 33 rivers in china have reached their highest levels in history. at least mi people have died in the floods. in spain, real madrid have won their first la liga title in three years with a game to spare as they beat villarreal at an empty alfredo di stefano stadium. they now have unassailable seven—point lead over second—placed barcelona. zinedine zidane's side have won all ten of their matches since spanish football restarted in june. scientists have warned that rising global temperatures will increase the risk of people suffering "heat stress". this is more thanjust feeling a bit hot. when the body can't cool down, it can lead to a range of serious health problems. it's already a big problem for those who work outside in hot countries. but medical staff have experienced

similar problems wearing ppe during the coronavirus pandemic. our science editor david shukman has this report. in the tropical heat of singapore, the medics are dripping with sweat, literally. they're caring for patients with covid—i9 but there's no air conditioning and the personal protective equipment makes them even hotter. the risk is that hospital staffjust keep working but then collapse from what's called heat stress, where the bodyjust can't cope. heat stress can happen when there's a combination of two different factors. the first is a high temperature and the hotter it gets, the more the body tries to protect itself by sweating. the evaporation on the surface of the skin helps to

keep the body cool. but, if at the same time there's a high level of humidity, with a lot of moisture in the air, well, then that process of the sweat evaporating can't take place, cooling doesn't happen, the body becomes overheated. that can lead to anything from dizziness to fatigue, to failure of the kidneys. this device measures that combination of heat and humidity and the worry is that as climate change makes the world hotter, working conditions for many will become even tougher. this matters for millions of people, especially in developing countries. from brick makers in india, risking their health out in the open to earn a living... ..to construction workers in the already sweltering gulf. scientists say that heat stress could become the next big threat after the coronavirus. i see this pandemic almost like a full dress rehearsal for what is to

come. this climate change, global warming, will be a bigger monster and we really need coordinated efforts across nations to prepare what is to come. luckily, there are ways to help. resting in shade is the most obvious solution for people working out of doors, along with fans to keep the air moving and having plenty of water. researchers have found that simple steps make a real difference. if you can take a complete break, sit down and rest, take on some cold water and be seated in the shade with some air flowing through and allow yourself some recovery during that work day, we are seeing that have a significant impact in the health of the workers that we're working with. back in singapore, the hospital lays on semi—frozen drinks to help the staff cool down. many other employers don't think about the impact of heat

on their workers but there's growing evidence that they'll need to as global temperatures rise. david shukman, bbc news. stay with us on bbc news. still to come: what does a new study analysing millions of tweets reveal about our emotions during the coronavirus pandemic? after months of talks and missed deadlines, a deal has been struck to keep greece within the eurozone. the immediate prospect of greece going bust, in the worst crisis to hit the eurozone, has been averted. emergency services across central europe are stepping up their efforts to contain the worst floods this century. nearly 100 people have been killed. broadway is traditionally called "the great white way" by americans. but tonight, it's completely blacked out. it's a timely reminder to all americans of the problems that the energy crisis has brought to them. leaders meet in paris

for a summit on pollution, inflation and third—world debt. this morning, theyjoined the revolution celebrations for a show of military might on the champs—elysees. wildlife officials in australia have been coping with a penguin problem. fairy penguins have been staggering ashore and collapsing after gorging themselves on their favourite food, pilchards. some had eaten so much, they could barely stand. this is bbc news, the latest headlines... the us, canada, and britain have accused russian intelligence mounting a campaign of cyber attacks against organisations trying to develop a coronavirus vaccine. the british schoolgirl who ran off to join the islamic state group, wins a legal battle to return home to fight the removal of her citizenship. within the past few minutes, brazil

has reached another grim milestone in the coronavirus pandemic. the health ministry has just confirmed that the number of confirmed cases has surged past the two million mark. it's now the worst—hit country in the world, after the us. and the brazilian president jair bolsonaro, is among those who've tested positive for the virus. despite that, he's encouraging the country to re—open and return to normality. our south america reporter katy watson reports from sao paulo. in these frightening times, moments of comfort are everything. for two months now, this man has been in intensive care. he only has one working lung, it's unclear if he'll survive. dr andre asks if he's experiencing pain. all he can do is blink to say "yes". these are intense times for everyone. andre works on shift with his wife, dr fernanda.

they live this crisis together 21w. even here, brazil's top infectious diseases hospital, coronavirus has floored them. it was the first hospital to fill up in sao paulo and every day they are turning more people away. it's not physical, it's psychological. sometimes we fail and we have to deal with the family pain and theyjust couldn't see those patients, they are not here for them when they are dying. it's the loneliness that they feel, even if they are sedated. ifeel safe here, more than outside. really? it's a comment that says a lot. the president has shunned social distancing and regularly refused to wear masks, despite them being mandatory. the death toll keeps climbing and even now that he has the virus he is supportive of shops and restaurants reopening. there is little love forjair bolsonaro on this ward.

i think he was the worst thing that we can have in this moment. he was, he is in fact, irresponsible. he is a person without empathy and he said, "it's not my problem." so is it my problem? in the midst of grief politics doesn't matter, but everyone is affected. grave—diggers tell me that their work has tripled. no longer do they have hearses bringing in a body, they have vans bringing in five. people often say that this virus isn't visible, but the suffering here is so easy to see. i meet ada nielsen in latin america's largest cemetery. he is exhuming bodies today. with burials rising, space is at a premium, so those whose loved ones died more than three and a half years ago are

being asked to collect their bones. "the only thing a grave—digger is afraid of is getting covid, he says — he has been in the job for 25 years. his hours are long and it has got personal. his uncle was buried here just a few weeks ago, a childhood friend was also lost to covid—i9. ada nielsen says hisjob nowadays is also that of a counsellor, telling families to stay home and stay safe. "if people here understood the point of quarantine, we wouldn't be so busy," he says, "things would be different." for those who have passed, little chance to rest in peace in these challenging times. katie watson, bbc news, sao paulo. how've you been feeling during the coronavirus pandemic? even if you've had no physical symptoms of covid—i9, you may well have been through the wringer psychologically over the past six months,

as lockdowns have come and gone. a new study analysing millions of tweets from around the world has been mapping our emotions. and it's discovered that many of us have progressed from fear to anger. professor may lwin from nanyang technological university led the study and joins me now. very good to have you with us. tell us very good to have you with us. tell us about this study, what exactly we re us about this study, what exactly were you looking at, and what conclusions did you draw? well, you know, a lot of scholars have been finding negative emotions across what we call the whole info dimmick environment, with postings on social media. so we looked at tweets over a relatively long period, from january until the end of april. and we were looking at these negative

emotions in particular, and we were finding that this was really, you know, surfacing on different dimensions of negative emotions. so in particular, we know thatjust in the early months of this pandemic, as expected, we were finding a lot of fear. so tweets and posts pertaining to terror, worry about yourself, yourfamily and to terror, worry about yourself, your family and friends. but as the months progressed, the level of fear has subsided, and the amount of posts has also gone down on that fear dimension. and we have a lot more posts and feelings that pertain to anger surfacing. and this has been a really wild swing to because by april, it was catching up to fear. and right now, with the latest data that we have up until the end

ofjune, it shows that feelings of angen ofjune, it shows that feelings of anger, in particular relating to isolation, and then also components of xenophobia and so on, have been surfacing on social media. you just looked at twitter, so how representative do you think this might be, and which countries did you look at? was a global study? tell us more about the scale of this. you know, we looked at over 7 million original posts — or rather, the people who post on twitter. and we are of course is not representative of the whole globe, but we did had representation from 170 countries. and two different levels, the language representation was good with the exception of the

number of countries where the postings tended to be in their own language. so we do feel that in terms of the overall emotions in the global trends, this was pretty representative. and you did mention that you found a theme of xenophobia, as well, and some of those tweets. what more did you find on that very briefly? well, i think as expected, we did find these different trends, like i said, of fear and anger rising. then over time, there were a lot of components of sadness, as well. but there was a lot of... we have to stop you there, but thank you very much forjoining us. but thank you very much forjoining us. sorry, we are coming to the end of the programme. we will have the headlines in a few moments followed by the papers.

hello again, some place to stay cloudy. there was more sunshine it was warmer as well. temperatures reaching 22 celsius in hampshire during the afternoon. the temperatures weren't far behind, actually in the northeast of scotland, held by over eight hours of sunshine. let me set the scene for you, because at the moment we still have warm and humid air across the uk. that weather brings some patchy rain and drizzle to the north, cooler, fresher air is that cloud of band and patchy rain move southwards. england and wales still dry early in the morning. quite warm and humid start to the day. that cloud and mostly light rain will continue to trickle southwards across scotland, northern ireland, eventually into northern england and later into north wales. to the north across northern scotland, it will brighten up. there will be some sunshine. not quite as warm as it was on thursday, but still 20—21. further south, a rain band across england and wales, some sunny spells, turning out to be quite warm.

26 or even 27 in the southeast of england. now that weather front bringing that cloud and rain will continue to move southwards overnight and into the start of the weekend. it's a painfully slow process, mind you, and we'll see that rain moving away from much of northern england as it heads into wales, through the midlands, perhaps lincolnshire and eventually the southwest of england. the rain does tend to die out in most places. still dry towards the southeast, quite warm here. temperatures perhaps 2a degrees or so, and further north, we've got that cooler air moving down, and temperatures will continue to drop away a little bit. for the second half of the weekend, we see that weather front continuing down towards the southeast. as it arrives here on saturday night, the rain could turn steadier and heavier. once that rain clears away, we're all getting into that cooler and fresher air from the northwest. still some rain to begin with on sunday morning across east anglia and the southeast. once that clears away, we'll have some sunny spells. a few showers around, mostly towards the northwest of scotland. many places will be dry in the afternoon, but the air is cooler

and fresher everywhere. we've got temperatures typically 16—20 celsius. that's a little below par for this time of the year, and we'll keep those sort of temperatures for the early part of next week. maybe one or two showers around, but many places, i think, will be dry. we will find some spells of sunshine at times. goodbye.
