quarter—final against colombia, keira walsh speaks to us about her injury and quick recovery at the women's world cup. good evening. "we go to great lengths to hide what we do, even from our children." the words of a serving officer in the police service of northern ireland, where there is shock and anger about the safety of staff — after details such as the name, role and work location of every individual were accidentally published online. more than 300 police officers were murdered in northern ireland during the 30 years of violence known as the troubles, and officers fear that republican paramilitaries might use the details to plot new attacks against them. the psni has apologised and blamed "human error" for the leak. and tonight a second data breach involving the theft of a laptop and documents has emerged. our ireland correspondent chris page reports. police everywhere deal with danger. in this part of the uk, the risks are especially stark. members of the police service of northern ireland take particular steps to protect their identities. but yesterday information appeared online about all 10,000 staff, both officers and civilians. they're absolutely horrified that their personal details have been shared in this way. telling you the length of service they have. they haven't told their family what they do and now it's all out there and they are really frightened, actually. the bbc has spoken to the two serving officers. one told us: another said: this local councillor, who left the police two years ago, is familiar with the threat. anyone who has an officer's name in mind to target want to know two things — they want to know where they live and where they work. and essentially what has happened is that this breach of their person data has done half thejob for them. during the conflict known as the troubles, more than 300 police officers were killed. attacks are much more rare now. however, officers still face challenges which come with community divisions. earlier this year, paramilitaries tried to murder a detective. john caldwell was shot by the new ira, a dissident republican organisation which is opposed to the peace process. the political leaders say the security situation makes the data breach all the more concerns. well, what we need to do now is get to the bottom of it, find out how it happened, why it happened and there needs to be accountability in terms of that. what i want to see now is a robust response from the senior- command of the psni to deal| with this very serious security breach and to reassurei their officers and staff. what is known so far is that the problem came about after a routine request for data under freedom of information laws. but the police also released a huge exel spread sheet by mistake, containing the personal information. late this afternoon, the police said they were investigating another breach. injuly, documents and a computer were stolen from a car, including the names of 200 workers. well it is understood the chief constable simon byrne has cut short his holiday and he will be questioned tomorrow by politicians in a meeting of policing board. it isjust in a meeting of policing board. it is just a few months since the official terrorism threat was raised after the murder ofjohn caldwell and members of the security services are aware they are potential targets and regularly have to check under their cars for bombs. it is also the reason we don't know officers' faces in our reports. what the thousands of people affected by these breaches will be looking for is a full assessments of the security implications. thank you. 41 people have died after their small boat capsized as they were trying to make the crossing from sfax in tunisia to italy. four survivors were rescued by a merchant vessel and then handed over to the italian coastguard. the shipwreck took place near the island of lampedusa, which has become a gateway for people seeking safety and a better life in europe. i'm joined now by our diplomatic correspondent, caroline hawley. what more do we know about what happened? well what we know is from those four survivors that there were 45 migrants and they were heading from sfax to italy. they left last thursday. a few hours into their journey the boat was hit by a wave and capsized. most on board didn't have life jackets. you can see how small and crowded the boat is. so the survivors were picked up. two men, one woman, unaccompanied 13—year—old. they apparently survived by holding on to life jackets and the inner tubes of tires. had they not survived, we wouldn't have known about this, because the un said some boats just sink without trace. the reason we

deal with the large numbers of people trying to reach their shores. the eu signed an agreement with tunisia to stop smuggling and return migrants, the uk is putting people on barges s. the un says there must be more legal and safe routes for people to claim asylum in europe and the uk. ., ~ _, 11 people have died in a fire at a french holiday lodging where young people with learning disabilities 11 people have died in a fire at a french holiday lodging where young people with learning disabilities were staying. the cause of the fire in the town of wintzenheim, near the border with germany, is not yet clear. 17 people were evacuated from the building, and at least one person has been taken to hospital. france's prime minister visited the site and spoke to rescue workers. translation: this is obviously a terrible tragedy and i would i like to express my deepest sympathy and solidarity with the families who have suffered so much. it's something that affects us all at the height of summer in alsace. it's still too early to draw any conclusions. an investigation is under way and will shed full light on the matter. hundreds of firefighters have been tackling a series of wildfires in portugal. although the country often suffers summer fires, these come amid a ferocious heatwave with temperatures reaching 46.4 degrees celsius this week. it's the latest in a series of fires to affect europe and the wider world this summer. last month, on the greek island of rhodes, thousands of tourists had to flee their hotels as wildfires ravaged the holiday hotspot. during a heatwave in southern europe, fire on la palma, in the spanish canary islands, forced thousands from their homes. and smoke from wildfires in canada drifted down as far as new york, where the sky turned orange. back in portugal, the fire in the area around odemira has mostly been put out, but authorities are on high alert for it spreading. our correspondentjenny hill sent this report from the affected region. scorched earth still smouldering. the fires consumed 40 square miles of land. here, flames swept up the valley, right up to the southern town of odemira. on the outskirts, destruction, but somehow the community itself was spared. they have been battling the fire for five days now. it's difficult, dangerous work. earlier the authorities announced it was under control, but the fire is still burning and the wind is shifting — too soon to say it's over. for those who live here, traumatic times. translation: it was horrible, there was fire _ translation: it was

see it on the sky — enormous flames and lots of smoke. thanks to the efforts we kept the fire out of this vineyard. it is perhaps too soon to assess the damage done. there is a really strong smell here, it is not just the smoke, it is eucalyptus and pine — those are the trees that line this landscape and they have been consumed by the fire. after three heatwaves the ground is now extremely cry and extremely vulnerable. and with temperatures set to stay high, uneasy days lie ahead. jenny hill, bbc news. well, more than a thousand firefighters remain at the scene and aircraft are at work, about 10, we have seen them fetching and dumping water on the area. it has been a day of encouraging news and the temperature is cooling here as evening falls, but they're concerned about the night and worried that the changing winds which restart the fire. i had a chat with a firefighter who said to me, we feel better about the situation, but it is not time to relax yet. thank you. so what 5 the science behind wildfires that we are now seeing all over the world and how are rising temperatures impacting the size and location of theses fires? our environment correspondent matt mcgrath has more details. from siberia to spain, across parts of china and the us, severe wildfires have raged this year as never before. in many locations around the world this year, lives have been lost as fierce flames have turned homes, hotels and businesses into ash and cinders. scientists can't directly link these fires to climate change. often, the spark of ignition comes from a human hand or a natural event like lightning. but scientists are clear that rising temperatures are increasing the conditions in which these fires can thrive. the number of fire weather days, classed as times when vegetation can burn most easily and fires can burn most fiercely, are increasing significantly. this can be seen most clearly in the mediterranean region, where fires driven by heat and wind are turning forests into dark, barren landscapes. in the mediterranean, we're not only seeing one of the fastest rates of temperature increase around the world, we're also seeing a phenomenon that leads to more fuel accumulation. a lot of rural areas are now depopulated, and that means they are not tended any more. we have less grazing and therefore more vegetation growth. that makes the landscape even more flammable. closer to home, all parts of the uk are expected to become more susceptible to wildfire as the climate changes. here in south wales, they've already seen over 800 wildfires this year, including here on rhigos mountain. there's been a change for us now. where we used to have fires around the easter holidays, that time, those fires were milder. now what we're moving into is summerfires. they're becoming a big problem for us. the fuel dries out, the ground dries out. we're having long periods of no rain, and the fires become a lot harder for us to put out. forest fires also pose another challenge. they release huge amounts of carbon back into the atmosphere. in canada, co2 emissions from wildfires from january to july were more than double the previous record for a whole year. all that extra carbon boosts warming, driving heatwaves and droughts, and likely exposing millions more people around the world to this growing threat of wildfires. matt mcgrath, bbc news. a wonky building in south staffordshire which was a lopsided landmark for many years and which was destroyed in a fire at the weekend has become the centre of a major controversy. the 18th—century crooked house pub, which got its name and appearance from subsidence due to mining, was gutted by fire on saturday night. on monday afternoon — it was bulldozed — by whom, no—one knows. council officials say the demolition was unacceptable and possibly unlawful. let'sjoin our midlands correspondent, phil mackie, who is there for us now. yes, lots of questions still to be answered, as you hinted there. it's always been a bit of a tourist attraction here. it has become even more of a magnet for visitors over the past couple of days as locals gather to reminisce about the place that they loved. for many of them, this has been a familiar sight throughout their lives. this is all that remains of a much loved landmark. a week ago, what they used to claim was the world's wonkiest pub was still standing. in march, the pub�*s owners put it up for sale and locals started a petition calling for it to be kept as a pub. onjuly 27th, the pub�*s facebook page said it had been sold to a private buyer for alternative use. the fire broke out on saturday night. the building was gutted and an investigation was launched to determine its cause. firefighters confirmed they hadn't been able to access the site easily after a mound of soil had been used to block the road. on monday afternoon, footage emerged showing what remained of the building being demolished by a mechanical digger. people had been coming to see the crooked house for decades. the crooked house, where even teetotallers can feel tipsy. and it could be a mind—blowing experience. i sort of grew up coming here on my bike as a kid. paul turner first came here as a little boy, and as soon as he heard it was up for sale, launched the petition to save it. to look at this when just a few days ago, it was a pub that could just be used without very much work at all, is absolutely devastating. if it was started deliberately, the fire investigation dog may be able to help work out how. but for the hundreds who gathered here to address their anger at the pub�*s demise, there are also questions about why the pub was completely demolished, even when some of it was still standing. the local council's launched its own investigation. we have never given permission to the owners to demolish this pub. what was the reaction, then, when you saw it happen? what have you said to them? we did give them permission to demolish or remove the first floor that was unstable, to make it safe. which has meant what happened in the final days of the crooked house has led to increasing anger. phil mackie, bbc news,

facing legal action over claims that they under—reported the pollution they cause and overcharged customers. the law firm bringing the claims says customers could be in line for around £40 each in compensation, though the process could take years. the water industry has dismissed the accusations as "without merit". ben king reports. a rising tide of anger about sewage in seas and rivers is spreading across the country, now followed by legal action. every water company has an agreement with the two regulators, the environment agency and ofwat, and it's our contention that they have been underreporting the extent of the spills of sewage that they have created because by underreporting, they are seen as hitting their targets. and if they hit their targets, they are allowed to charge their customers more for their services. every bill payer will be part of the case unless they opt out. professor roberts and lawyers leigh day plan to bring similar cases across against five more water films including thames, united utilities, anglian, yorkshire and northumbrian. severn trent says, "this is a highly speculative claim with no merit which we strongly refute. should pollutions ever occur, they are always reported to the environment agency. any claim to the country is wholly and completely wrong". this is the river sowe, not far from severn trent's coventry ho. now, the environment agency is investigating the water industry and injune, it said that it had found widespread of sewage breaches at all the companies it looked at. even the big companies have been doing it quite a lot, putting all the toxic waste back into the rivers. it's terrible, it needs something being done about it anyway. i think it's disgusting, polluting the rivers and what's happening to our wildlife. we really need to do something about it. it could take years, but if professor roberts' claims succeed, customers could get compensation of around £40 each. but it's notjust about money. she hopes it will force water companies to clean up their act. ben king, bbc news, coventry. our top story this evening. police officers in northern ireland speak of fear for their safety after their personal details are published by mistake. still to come, we hear why the names of thousands of people who were adopted as children have been removed from a genealogy website. also this evening: the woman who stopped fostering after being prevented from staying in touch with the children she cared for. worth about £60 million in total. it's commonly thought that the rise of social media has increased problems with mental health — but a new study challenges that. the research done by the oxford internet institute looked at the rise of facebook and how well—being was affected in 72 countries. here's our technology editor, zoe kleinman. if you're one of facebook�*s 3 billion global users and you have sat scrolling through your timeline on the social media app, you may have found yourself wondering whether it is doing you any good. you're not alone. now researchers at oxford have tried to quantify its effects globally. in the largest study of its kind, facebook gave researchers 12 years of data showing how much it had grown across more than 70 countries, and comparing that to surveys on how well—being has changed in those countries. the big, and possibly surprising conclusion — there is no evidence that facebook�*s both is linked to widespread psychological harm. quite the opposite, in fact. it didn't look like there was a connection between negative impacts on positive _ connection between negative impacts on positive health and facebook. we found _ on positive health and facebook. we found some —— we found some evidence of the _ found some —— we

findings are too broadbrush to be useful, as it wouldn't have revealed whether smaller groups of vulnerable people experienced harm, orfactored in whether some types of content were more harmful than others. it also looks at only one social network, facebook. there has been an explosion of other social media sites over the past decade, and it doesn't include those. what everybody agrees on is that more research is needed. the report authors say that more tech companies should open up their data to independent research so that we can find out once and for how our of social media really affects our mental health.— mental health. zoe kleinman reporting- — the scottish comedian hardeep singh kohli, who has presented programmes for the bbc and other broadcasters, has been arrested and charged in connection with "non—recent" sexual offences. the 54—year—old has been released and is due to appear in court at a later date. his arrest follows an investigation by the times newspaper, which said several women had raised concerns about his behaviour. now, we've already heard about the serious concerns raised by the data breach in northern ireland — there's been another in scotland, where the names of thousands of people who were adopted were publicly available through the scotland's people genealogy website. details covering decades of adoptions dating back as far as 1909 were there — but they've now been removed by the site's operators after an adoptive mother complained they could endanger her child. our scotland correspondent david cowan reports. the scotland's people website allows the public to trawl the website for their ancestors. a search of all databases holds a vast collection of entries. but now thousands have had to be removed after an adoptive mother found details of her child. the information included the first name he was given at birth, his new surname and a reference to the adoption register. to protect the child's identity, the mother's words are spoken by an

traditionally, walking less than 5000 steps a day is considered the said entry and bad for your health. but actually, less than half that, just under 2500 steps a day still helps reduce the risk of dying from heart disease. and just under 4000 steps a day still helps reduce the risk of dying from all causes. and every single extra step helps. so the question is how much more? well, every extra 500 steps, there is a 7% reduction in the risk of dying from heart disease. every extra 1000 steps is associated with a 15% reduction in the risk of dying from all causes. forand reduction in the risk of dying from all causes. for and abdul, that is good news. they are aiming high and taking the family up this mountain in preparation for ben nevis. i don't count my steps. i get off a stop earlier and i walk. myjob involves a lot of walking and going up involves a lot of walking and going up and down stairs, but i don't count the steps.— up and down stairs, but i don't count the steps. this study looked at over 200,000 _ count the steps. this study looked at over 200,000 people - count the steps. this study looked at over 200,000 people of - count the steps. this study looked at over 200,000 people of all - count the steps. this study looked l at over 200,000 people of all ages and genders across the world. and it finds that doing more of this benefits every walk of life. hywel griffith, bbc news, near bannau brycheiniog national park. now, the stuff of nightmares — a texas woman was attacked by a hawk and a snake at the same time! it happened after the hawk — which eats snakes — accidentally dropped it on her. 64—year—old peggyjones was mowing her lawn — and must have had the shock of her life when the passing hawk dropped a wriggling serpent. the snake wrapped itself around her arm and began striking her face as the bird sunk its talons deep into herflesh. it was like, i couldn't believe what was happening. it was starting to tear at my face and it was striking my glasses. and it kept on and i couldn't get rid of the snake. it was like i went into survival mode. that is so grotesque! louise, take the image away, please. i thought the end were supposed to be a nice story and now i am going to tell you about the extreme heat which has been building in spain for the last couple of days. in andalusia this morning, we saw a high of 44 celsius. we are tapping into some of that heat today, but tomorrow the heat will bill further. we were seen widespread temperatures in the mid to high 20s. and we haven't had temperatures like that for quite some time. so we have got high pressure with us for at least a day or two, but things will change. through the night, we keep some clear skies inland. close to the coast, some patchy mist and coastal fog, particularly down to the south—west. some of that might be stubborn to clear away. increasingly humid as well, so a very mild night and i'll start to tomorrow. you will notice it when you are stepping out first thing. there should be lots of sunshine, particularly inland across england and wales. hopefully, some of that low cloud and mist the lift across the west. we will
