good afternoon and welcome to the bbc news at one. just days before the new school year, ministers have been defending their decision to order more than 100 schools in england to shut some of their buildings because of concerns about materials used in their construction. the government says new evidence emerged over the summer about a type of concrete that is prone to collapse. it means some pupils will have to be taught in different locations or online while safety work is done. at least 12 schools in scotland are also known to be affected, while schools in wales and northern ireland are to be surveyed. this report from our education reporter vanessa clarke. it's just days until the start of the new term, and this school in bradford is more is one of more than 100 across england that has been told it has to close some classrooms, where faulty concrete has been found. parents say that the school is working really hard to move students to different areas on site, but it is a worry. it is a little bit concerning that it's so close to going back to school. but these things happen, don't they? i'd rather my child not be in school, than the school fall down around him! the concrete known as raac is lightweight, and was used in many public buildings, mostly between the 50s and the 90s. it is usually found in roofs, and in some walls and floors. it is weaker than traditional concrete, and experts say that it has a life span of 30 years. many public buildings like hospitals and schools are affected. ministers say that they are now taking a more cautious approach, following recent cases where raac failed. what we learnt over the summer was that there are a number of cases in schools but also in non—school buildings and in england and outside england, where raac that we previously thought was safe or low risk actually has failed, so we took swift action to change the guidance yesterday. the problem was first highlighted five years ago. some are questioning why this announcement has been made so close to students returning to schools. we have been talking to the government for quite some time about this. it would be useful to know a bit earlier than we have done, a few days before children are due to go back, teachers will go back, in most cases before that, so it's important that we do get on with that but it would be nice to know in advance about that. however, local government is very resilient these matters, as our our education colleagues, as well. we will make this work as fast as we possibly can. this is one of at least a dozen schools in scotland that are affected. some in northern ireland and in wales are also being checked. structural surveys of hundreds of schools, colleges and nurseries in england with suspected raac are continuing, and more could soon be added to the growing list. vanessa clarke, bbc news. well, this type of concrete was common in construction from the 1950s to 1990s and is found in various public buildings, not only schools. our home affairs correspondent tom symonds is with me. how have we reached this point today? how have we reached this point toda ? , , , ' how have we reached this point toda ? , , , , , how have we reached this point toda?, today? yes, this stuff is called reinforced _ today? yes, this stuff is called reinforced autoclaved - today? yes, this stuff is called reinforced autoclaved aerated| reinforced autoclaved aerated concrete. these holes are a bit bigger because we zoomed in. you might think of it as being a bit like that chocolate bar a lot of people will know. as you say, it was used in lots of public buildings in post—war building work. and this is potentially going to affect potentially going to affect potentially courts, other public buildings, housing, potentially, ministry of defence buildings, a whole range but i think what this is really about is whether this problem is being managed properly. just to give you a little bit of history, in the late 90s, building research found that there could be a problem with this sort of stuff because the water that can get into these holes could cause corrosion especially to the reinforcing beams. the decision was taken, the advice was, it was essential to consider maintenance and inspection regimes but there was no obvious safety hazard at that point. the problem is time is past, this stuff has got older, climate change, more rain, more variation in temperatures, having an impact, and more building around removes these panels are used in, and it's simply become problem. now, a key statement made by the local government association in its advice is that it was thought you could inspect these panels and then tell if they were going to fail, but two recent failures in schools suggested that that can no longer be relied upon so i think that's what's happened here. as you start to inspect more and more building thinking you've got a problem, you find more and more problems and as a result, schools are being closed. 0ne problems and as a result, schools are being closed. one final thing to say is that the nhs seems to have got onto this problem a bit quicker than the department for education. hospital building programmes have prioritised getting rid of raac from hospitals and that's probably because hospitals have a much more organised system of building maintenance.— organised system of building maintenance. ., ~ , ., ., ., 0ur political correspondent, leila nathoo, joins me. is this shaping up to be very costly for government? i is this shaping up to be very costly for government?— for government? i think the government _ for government? i think the government is _ for government? i think the government is certainly - for government? i think the l government is certainly under pressure on this, the opposition parties, labourand lib pressure on this, the opposition parties, labour and lib dems are accusing ministers of dragging their feet on this issue, not taking it seriously, and not having a full handle on the scale of the problem. labour say their shadow education secretary has raised the safety of school buildings more than 150 times in parliament they claim so it's been a long—running issue. they are calling for the government to publish this list of the skills that have been issued with this new guidance, and ministers say they won't do that yet await for parents to informed and for the remedial work to be repaired. but we do understand there were three specific cases over the summer that because the department for education to change their guidance to schools, two of those cases were not in england, one of those cases came to the department's attention in late july, and there was a third case that occurred last week that is still being investigated in an educational setting in england, so they do say it appears there has been a specific case which has been the trigger for this new guidance where raac which was considered previously to be said, was now found to be a higher risk. it is also understood that there is a cross governmental working group on raac, so other departments have been contacted by the department for education, given this new information that came to light, but other departments including the department of health had their own programmes under way and at the moment it doesn't look like any other department is taking a new course of action given what the department for education has done. thank you. there are no rail services across large parts of england again today because train drivers are on strike, as part of their long—running pay dispute. members of the aslef union at more than a dozen rail companies are taking part and they'll refuse to work overtime tomorrow, when up to 20,000 workers from the rmt union stage separate industrial action. also, today is the last day of the public consultation about proposals to close hundreds of ticket offices around the country. people have until midnight to send in their comments. here's our business correspondent marc ashdown. deserted platforms, trains going nowhere. another 24—hour walk—out by train drivers in this long—running dispute. for passengers across the north of england especially, it's been a frustrating morning. i'm late for my patients actually. i'm a doctor. i'm supposed to see patients at nine o'clock. i think obviously they are doing it for a reason, but then they don't realise how it affects people's lifestyles and work. i thought there was an essential service from stockport - to manchester but there wasn't, so there's literally _ no trains running. so i need to get into work. yeah, not ideal. around 12,000 members of the aslef union have been taking part in industrial action for more than a year. they rejected a pay offer of 4% last year and the same again this year. with no fresh talks planned, a resolution looks as far away as ever. i'm normally an eternal optimist and i flippantly said about a year ago i hope to resolve this before i retire. i go in two—and—a—bit years and i don't know. you don't hope to see this resolved before you retire? i want it resolved but i don't see any light at the end of the tunnel. meanwhile, campaigners marched on downing street yesterday to protest at plans which could see almost 1,000 ticket offices across england closed for good. train operators are under pressure from the government to cut costs. the industry says ticket buying habits have changed, so staff could be better deployed on other tasks. half a million people have been submitting their views in a consultation which closes today. because we don't travel regularly, if the ticket office was closed, and we did want to travel that might be a problem. i only buy tickets online. i do tend to use the e—ticket, but i can see people that do, | like my mum does, for instance. she doesn't do online. generally, ijust buy them from the machine but it will affect other people. unions fear fewer offices could eventually lead to job losses and concerns have also been raised around waiting rooms, toilet facilities and accessibility for disabled passengers, or those who need help buying tickets. this whole process is designed to address those issues individually at individual stations rather than just being a national referendum about ticket offices. it's unlikely to improve the mood as we head into another weekend of disruption. tomorrow, 20,000 members of the rmt union are set to stage their latest 24—hour walk—out, while aslef members will refuse to work overtime. the government says no final decision has been made on ticket offices and insisted the pay offers to both unions are reasonable and should be put to members for a vote. marc ashdown, bbc news. 0ur correspondent, tim muffett is at euston station for us. how would you assess what people are saying to you, what the mood is about all of this? the saying to you, what the mood is about all of this?— saying to you, what the mood is about all of this? the mood here is re about all of this? the mood here is pretty downbeat- — about all of this? the mood here is pretty downbeat. it _ about all of this? the mood here is pretty downbeat. it stopped - about all of this? the mood here isj pretty downbeat. it stopped raining and the sun is, but that's about as good as it gets. london 0verground services are still running from euston but nothing else is and all morning, passengers have been arriving here expecting to travel and a number of people have been telling me they are surprised to find out the trains are not running so a lot of criticism that this strike action hasn't been publicised enough. now nick whelan from the aslef union was here on the picket line earlier and i spoke to him and he says his union are in this for the long haul. the offer from the rail delivery group and the governmentjust simply doesn't rail delivery group and the government just simply doesn't take into account the effects of inflation. the department for transport says the offer is fair and reasonable and that it is frustrated by the dire situation on the railway this weekend. today, the strike by us left and tomorrow an overtime ban from aslef plus strike action by the rmt. it's going to be the end of the school summer holidays, football fans wanting to see again, as well, and if you are intending to take a train in england this weekend, we've said it before, we'll say it again, but please do check before you travel. there is a very good chance your train will not be running. thank you. two members of the far—right proud boys group in the us have been given long prison sentences for their role in the storming of the capitol building in washington dc. joe biggs, a leading figure in the proud boys, who are strong supporters of donald trump, was given 17 years. zachary rehl received 15 years. both men cried in court as they expressed regret for their actions on

annual decline since 2009, according to the nationwide building society. our business editor simonjack is here with more details. thanks, jane. house prices falling at a faster pace than we have seen for a decade. as you said, house prices are 5.3% lower compared to august last year in the biggest annual decline since 2009, according to nationwide one of the uk's biggest lenders. that means thatani2the average house prices in the uk peaked is now just over 259,000 pounds — a fall of nearly 15,000 since house prices peaked in august last year. so why is this happening? well this graph tells us most of the story as you can see, the cost of mortgages has rocketed — as the bank of england has raised interest rates to combat soaring inflation. an important note — these prices don't include cash buyers — who don't have to borrow money — and make up a surprisingly high 30% of property buyers. so where do we go from here? nationwide says it doesn't expect a crash — because unemployment is low and wages are rising and interest rate rises are expected to slow from now on as inflation pressures ease, but with rates expected to stay higher for longer — the housing market will remain under pressure. thank you, simon jack. in pakistan, several members of the family of a man who british police want to question about the death of his daughter say they've been illegally detained. the body of sara sharif was found at a property in woking in surrey on august 10th. police in pakistan have been searching for the ten year old's father, his partner and his brother but have

without correct reason to do so. that has happened twice, it happened last week when the police came out and promised they would not arrest arfan sharif and two is pakistan —based brothers, but we have not yet heard from the police, they have been given until monday to provide their response. meanwhile, of course, there is three from the uk still have not been found. we know that the search is

first time. noo—noouri is now on the books of warner music, and has released herfirst song, dominoes. our technology reporter shiona mccallum has been finding out about the implications of the deal. meet noo—noouri, she is a virtual character and instagrammed influencer, who has worked with big fashion brands. her appearance has been created using 2d graphics and motion capture and now this avatar has a record deal backed by a major label. oh, my god. this is amazing. it was accelerating my pulse, when i got the e—mail from warner music central europe, is writing me, and they were asking me, are you interested in music, and i was like, well, what a question! # start a chain reaction...# her voice has been created with the help of artificial intelligence. they pitched it higher, of course, they make it more female, but they didn't want to create, like, a human voice, we wanted to have it a bit like technology, a bit tech—voicey. so, the base, the original voice of her, is my voice. and, to make the sound, they got a singer involved, too. here comes the moment where we use ai technology. the voice from the singer. we needed to know when he was singing high, when he was singing low, when he was singing slower, when he got more speed, when he got more pressure. warner is releasing noo—noouri's first single. whenever it comes to appearances in metaverses, in gaming, when you want to experiment with motion capture technology and so on, noo—noouri is a perfect fit, here. she can appear in different places at the same time. you can change her style in a minute, we can make noo—noouri fly if we want because it is natural to her, because she is already a digital character, so, there are more opportunities than with human artists in that respect. al was only a small step in the creation of this song. producers and songwriters all over the globe contributed. like any new technology, ai brings with it immense opportunity but also raises profound challenges for the creative community. it is about understanding that transparency. it is about knowing what data and what content ais have been trained on, it is about ensuring there is adequate labelling so that we know whether or not a piece of music is al generated. but also there are questions about personality rights. at the moment in the uk, personality rights aren't really properly protected. you can essentially generate an ai version of someone, of a pop star or a singer, and that they wouldn't have any rights about how that is used, so, looking at how we can ensure the regulatory and legal framework around ai, so that it is used in a way that can enable human creativity creativity not erode it, is absolutely critical to our position in the music industry. clearly, the use of ai is becoming more mainstream, but now that it's officially will it ever get to number one? # watch them fall, domi—dominoes...# shiona mccallum, bbc news, berlin. one of the world's rarest turtles is settling into her new home after she was found washed up and freezing cold on a beach in north wales. tally, as she's become known, is thought to have been swept 4,000 miles across the atlantic by strong currents. now she's back in warmer climes after a major rescue back home in texas and straight back in the water. tally can truly be described as a well—travelled turtle and an extremely lucky one, too. alive today, thanks to the kindness of strangers. this is her incredible story. it was two years ago that the turtle was found washed up in north wales, named tally after talacre beach, where she was spotted by a dog walker. my dog was making a bit of a fuss over what i thought was a pile of seaweed and then walked over and obviously saw that it was a turtle. initially thought that it was dead — unfortunately but still thought it's a bit weird for a turtle to be in wales on talacre beach. i don't see many turtles walking the dog usually. the experts at anglesey sea zoo were called in to try to nurse tally back to health, but there was no guarantee she would survive. she'd normally live in water temperatures of 2a degrees, so the eight degrees of the sea off wales meant her body had started shutting down. but day—by—day, she grew stronger. she got her appetite back. eventually, it was determined she was well enough to go home. tally is a kemp's ridley turtle, a critically—endangered species mainly found in the gulf of mexico. but young turtles can sometimes be swept across the atlantic that's how tally ended up on the beach in talacre. but her 4,000—mile journey home all the way to texas was a military operation. the raf helped transfer tally from anglesey to heathrow for her onward flight. a rescue charity described the mission as the furthest and most complex they have ever been involved in, 22 hours of travel in total, but months in the planning. she was accompanied on her journey by her rescuers. when you first got her in the pre—release thank you would not know that she had been on this enormous journey. she swam straight off, really enjoying being back in sea water, and she had her medical examinations and tests and had the all clear so we are waiting on blood test results. tally�*s immediate home is now houston zoo, but the plan later this month is to release her back into the sea in the gulf of mexico. it's hoped she will help ensure the survival of her species and she'll be fitted with a tracking device, meaning we may not have heard the last of tally�*s amazing travels. now to a football league with a difference because in scotland's warriors premier league, every player is overweight. they have to be, to be allowed to take part. the idea has been a success in helping people get fit, both physically and mentally, and make friends. tricia brown reports from the final match of the season. there's no name engraved on this trophy, because here at townhead park in cumnock, it's the very first time it'll be held high by the winning team of the warriors premier league — a football league with a difference. we have a specific player criteria forjoining, so anybodyjoining the league has to have a 38 waist round the belly or above the belly button, bmi of over 30 and you need to be 18 or over. 0riginally it was an overweight men's league, but we're pleased to see that there's actually women joining the league next year as well. in one of our new teams so, it's actuallyjust an overweight footballers' league now. for the players here today, the chance to get back on the pitch was something many never thought they'd have. maybe because of their age or the size, not being able to find the club that they'll get regular game time and play football. having that buzz again about being back in matchday squads and having games, even myself and shaun, games as friendlies, going along and just coaching the guys and supporting them, i think it's made a massive difference. it isa but but it's more mental health side. mental health fitness, which is kind of like you said, got me back in a good environment with a good bunch of people. and it's this camaraderie which is so crucial to many of the players. go for it! coming out of covid it was really difficult for for me personally, i felt the social aspect, really went, especially like working from home and stuff, you know, you go to the office, you're collaborating with people, you're talking to people all day. whereas if you're in the house, you're kind of left to your own devices and you know, mates, for whatever reason, you know, you just kind of as you get older, people's circumstances change, you go your separate ways. so, socially, for me, it's been incredible. everybody in the team's got different issues of their own. and when you get on the park, everybody forgets about their issues and you just become a team, play for each other, after a hard—fought match, it's the ayr eagles who triumph over the corstorphine goliaths with a 3—1win. but it's clear that for these players, it's the taking part that's just as important as seeing their name on that trophy. yaaaaasss! tricia brown, bbc news. now, what were most of us doing at the age of 13? bly twoomey will be competing for great britain at the european para table tennis championships which begin in sheffield next week. what's more, she'll be playing doubles with the reigning world champion, who's told us she could become the best paralympic player in history. 0ur sports correspondent andy swiss has been to see bly in training. going for european glory atjust 13, bly toomey proving age is no barrier to brilliance. bly, who has cerebral palsy, only began playing two years ago at her local club in brighton, but in may she won her first international medal. and to her friends and teachers back at school, she's already a star. they do assemblies about me and they... whenever i walk pass them, they're like, "oh, you're the table tennis person" and stuff like that. i practice four hours a day, five hours a day. i'm so happy because i'm a young age, so i didn't think i would be representing great britain now. what's more, she's playing doubles with the world champion. when will bayley was welcomed home from the last paralympics, he spotted bly�*s talent. well done. they began training together at brighton and now they�* re competing together. bailey, at 35, a mere 22 years her senior. it does make me feel very old, but i couldn't be more proud. i thought i was competitive and i am fiercely competitive. she's another level. i saw him on telly. i saw he won a gold medal, but when he went to the club i was so happy because i could finally meet him. she had so much energy. when i saw her she just wanted to play and she wanted to play me. she was hitting the ball past me. so it's like she's the boss of the doubles and i'm walking around going, "0k, bly, i'll do that, i'll do that, you know." so it's great to play with her. she's obviously incredibly talented, butjust how far do you think she can go? she'll be the best ever, best paralympic player we've ever seen. i'm proud to say i've won six paralympic medals, been to three finals in a row. you're going to do more than i've ever done. how does that sound to you, bly? yeah, it's very motivational. i've always dreamed to get to the paralympics and to get gold, it'll be just so much. just 13 then, but already mixing with the best. british sport could have a new smash hit. andy swiss, bbc news, sheffield. fantastic. good luck to her. time for a look at the weather. here's ben rich. 0ne one thing that has not been a smash hit has been the weather over the summer. it was the hottestjune on record but then july turned cool and wet and august was unsettled. meteorological speaking the first day of september is the first day of autumn and the weather is changing, turning drier, warmer and sunnier. we have quite a lot of
