a policeman is critically ill in hospital, after what's described as a "frenzied" machete attack in east london. it happened during a routine vehicle stop, with the officer, stabbed several times. what it shows to me is the vital importance of investing in policing. that's why we're putting another 20,000 officers out on the street. a 50—year—old man has been arrested. we'll be live at the scene. also this lunchtime... a dramatic rise in women and girls carrying knives in england, up 73% in five years. scientists warn food production must be sustainable. cutting down on meat and dairy will help tackle global warming. torrential rain leaves five trains stuck on the main edinburgh to glasgow line, after the drainage

system is overwelmed. and a new footbridge connecting two halves of a medieval fortress at the legendary site of king arthur's castle. and coming up on bbc news: the transfer deadline is fast approaching. arsenal have agreed an £8 million deal with chelsea to bring in defender david luiz. good afternoon and welcome to the bbc news at one. detectives have described a machete attack on a policeman in east london overnight as "frenzied, unprovoked and shocking". the patrol officer was stabbed several times during a routine vehicle stop of a van in the leyton area. scotland yard says he was "seriously injured" but will recover. a man in his 50s has been arrested.

andy moore is at the scene in east london for us. we have an update from the met police and they say he is stable in hospital. he was due to have an operation on his hand this morning. 0ne eyewitness said when he first saw the police officer lying on the ground behind me, lying motionless, being treated by his fellow colleagues, actually thought that police officer was dead. it should have been a routine stop, but it turned into what police described as a "frenzied, two minute long attack". after a brief police pursuit, a large white van was pulled over. the driver, in his 50s, became aggressive and pulled out a machete. we could see the van and the officer was there. he just got attacked and obviously me and the missus were standing

here, talking about it. we felt really sorry, not only because it was a person lying on the floor, but on top of it because it was a police officer, like the person who is actually responsible for our safety and stuff on the streets. as the police investigation began, the officer was being treated in hospitalfor his injuries. a wound to his head required stitches. he was due to undergo an operation for the injuries to his hands, sustained in trying to fend off his attacker. police say the incident was filmed on a body worn cameras but they are still seeking witnesses. the members of the public over there — i would urge you to come forward. while we've got a man in custody, we need to get to the bottom of why this happened and the fuller picture of what happened just before and then during the attack. the prime minister has paid tribute to the bravery of the police officer. what this underscores, for me, is the bravery of our police people, who actually go towards danger to keep us safe. 0ur sympathies are obviously with the officer and his family.

i think you've got to give officers the confidence that they need, that when they ask somebody coming towards them, who may be carrying a knife, which is a danger to them and to everybody around them, that they have to have the power and the confidence to do that emotionally challenging thing and do stop and search. a man has been arrested on suspicion of grievous bodily harm. police say it's not being treated as a terrorist attack. and some more information we have just had from the police. the man arrested we now know is 56 years old and the second police officer in that patrol car who actually made the arrest, she was a female policewoman. thank you, andy. andy moor in east london. there has been a dramatic rise, in the number of women and girls caught carrying knives in england. figures obtained by bbc news, show a 73% increase in offences over the end past five years, with nearly 6000 cases recorded. youth workers say some women end up carrying weapons for gangs,

because they're less likely to be stopped by the police. sarah corker reports. the first thing i would go do is run for a knife. i would go for a knife — threaten, cut. as a teenager, carrying a knife as part of everyday life and louise ann. then, in her 20s, it was a way to protect herself in abusive relationships. i remember, i used to have knives in my backpack. i used it to threaten people. give me what you've got, take it off of them. i used to sleep with a knife under my bed, because i started to get quite paranoid. i remember my boyfriend bought me this...he actually bought me knives. data shows women carrying knives is on the rise. in the west midlands, these weapons were found hidden in a designer handbag. women are often overlooked or ignored when it comes to tackling britain's problem with knife crime.

it's framed as a male problem. but figures obtained by the bbc show that, on average, one woman is caught carrying a knife here in the north of england every single day. in england, there's been a 73% increase in knife possession cases involving women in the last five years. since 2014, there's been more than 5,800 cases of women caught carrying knives. around a quarter of those involved girls under the age of 18. we have got girls that stab. youth workers say some women willingly carry knives to rob people, while others are vulnerable and exploited by men. they're wanting to belong. they're yearning for that so much that it doesn't matter what they go through in order to do it. so, knife, gun, drugs — there the couriers for it, you know? is it because they're less likely, they think, to get searched by police? well, they're not going to get stopped by police.

across england and wales, seven forces, including south yorkshire police, have been given extra powers to tackle violent crime. police! specialist officers target known trouble spots and have a more visible community presence. i don't think it's any more nuanced for women than it is for men. it's about vulnerable young people getting drawn into the fringes of organised crime. but others say part of the problem is the perception that women don't commit knife crimes and there is need for more policies targeted specifically at women. because they don't end up in the criminaljustice system in the same way as boys, the focus is not there. so, i think we need to be looking at our youth offending teams, the services that we're providing for young people, to make sure we're actually addressing the issues that are causing young girls to get involved, as well as the majority who are young boys. women carrying knives has often been described as a hidden problem,

but with the numbers increasing, the pressure is now on police and politicians to tackle it. sarah corker, bbc news. climate scientists are warning that high consumption of meat and dairy produce around the world is fuelling global warming. researchers say intensive farming releases carbon into the atmosphere, helping to raise temperatures. now, the united nation's intergovernmental panel on climate change says more people could be fed using less land, if there was a cut in meat consumption and a switch to plant—based diets. our environment alanyst, roger harrabin reports. this alpine landscape was once covered by forest. the trees sucked carbon dioxide from the atmosphere and regulated the climate. then, humans cleared some of the land for food. but cattle burp methane, and that strongly heats the atmosphere.

this sort of low—intensity grazing may produce protein from poor soil, and it does have some environmental benefits, but it still creates more greenhouse gases than growing plant protein. scientists meeting here in the alps are not saying we've all got to go vegan to protect the climate. they are saying that we do need to cut down on red meat and dairy produce, and shift on towards eating more vegetables. and that message may not go down very well here, in a region that is so heavily dependent on cheese and meat. we need to do what we can on the land, but actually it is important to maintain food production and so there will always be some emissions on land. so, in fact, we have to do as much as we can with the energy and industry and other sectors, as well. we have to do everything now really, if we're going to have any chance of avoiding the worst impacts of climate change. debate here has been fraught because the way we use the land is so complex. among the experts‘ recommendations

are: on biofuels, limiting the area used to grow trees to be burned to make electricity. this could conflict with feeding the world. 0n deforestation, working harder to protect the trees that protect us from climate heating. 0n desertification, finding ways to feed people that don't involve degrading the soil through overgrazing. then, there is the way we eat. in the west, we over consume meat and dairy. that is bad for our health, it is bad for climate, it is bad for water, it is bad for land degradation. if we were able to adjust that consumption in the west, of meat and dairy, then we could have significant benefits for the climate, but also for our health. scientists also want to stop food being discarded, because wasting food means the greenhouse gases created to produce fertilisers to grow the crops have been for nothing. a charity in geneva redistributes waste food. here they are taking stale bread and turning it into new cookies.

this avoids having to produce fresh flour to make the cookies. here is a positive sign, these peat moors in the north of england were previously drained, so animals can graze. when peat is exposed to the air, it is of greenhouse gases. so now they are blocking up the channels to succeed peat again. one of the easier options in what the scientists say have become an increasingly desperate attempt to stop the front —— planet overheating. roger harrabin, bbc news. a teenager is to face trial next year accused of throwing a six—year—old boy from a viewing platform at the tate modern gallery in london. the 17—year—old appeared this morning at the old bailey, accused of attempted murder. 0ur correspondent, danjohnson, was in court. what more happened in court? this was a relatively short procedural hearing here at the old bailey this morning. the 17—year—old, who can't be named for legal reasons because of his age, appeared here wearing a

light blue polo shirt. he only spoke to confirm his name, his date of birth and the fact that his nationality is british. he hasn't yet indicated whether he intends to plead guilty or not to the charge of attempted murder and his defence tea m attempted murder and his defence team had said that they want a psychiatrist to assess whether he is actually fit to make that play or not. so there will be a report, a background check done on him now. he is accused of throwing the six—year—old french boy of the viewing platform at the tate modern on sunday in what is described as an unprovoked attack. there were representatives here in court today from the french consulate, we believe on behalf of the french boy's family. they were in london on holiday essentially, when this happened on sunday afternoon. the teenager was told he will be held in youth custody until the next hearing, another procedural hearing which is expected in november. and if we get to a trial in this case, thatis if we get to a trial in this case, that is expected to be in february of next year. 0k, thank you. dan

johnson at the old bailey. borisjohnson has responded to questions about what he would do if he lost a vote of confidence in the house of commons, by insisting that mps should get on and deliver brexit. 0ur political correspondent jonathan blake is in westminster. so, what has the prime minister been saying? very little that he hasn't said before but with mps away on their summer before but with mps away on their summer break, the government appearing to intensify preparations for a possible no—deal brexit and no sign ofany for a possible no—deal brexit and no sign of any movement in brexit negotiations with the eu, there are big questions hanging in the air here at westminster. namely, how will mps intent on preventing the uk leaving the eu leaving without a deal go about doing that? and if and whenjeremy deal go about doing that? and if and when jeremy corbyn deal go about doing that? and if and whenjeremy corbyn tries to deal go about doing that? and if and when jeremy corbyn tries to false deal go about doing that? and if and whenjeremy corbyn tries to false a vote of no confidence in the government and boris johnson vote of no confidence in the government and borisjohnson were to lose that, what with the prime minister then do? resign immediately oi’ minister then do? resign immediately or sit it out for a two—week period which would be triggered before a

general election becomes necessary and attempt to schedule that that after the brexit deadline? these questions were put to borisjohnson ona questions were put to borisjohnson on a visit to oxford earlier this morning and he didn't really want to engagement had something of a warning for mps. we are going to leave the european union on october 315t, which is what the people of this country voted for. it's what mps voted for and it's what i think the parliamentarians in this country should get on and do, thank you. you're not concerned about disregarding the will of parliament? i think that mps should get on and deliver on what they have promised over and over and over again to the people of this country, they will deliver on the mandate of 2016 and leave the eu on october 315t. thank you. afamiliar a familiar message from the prime minister there. mps may be away on their summer holidays but as one said to me this morning, whatsapp is a wonderful thing and they like and there is a stand—off between the government and parliamentarians keen

to avoid a no—deal brexit as something of a game of poker, with neither side wanting to reveal their hand. sooner or later, though, they will have to put their hands on the table and decide what they want to do. i think in september we will be heading for another showdown in parliament. jonathan blake at westminster, thank you. more people than ever before attended accident and emergency departments in england last month. new figures also show record numbers of patients waiting for routine operations. 0ur health editor, hugh pym, is here. a&e attendances seem to be going up and up. yes, in a week when boris johnson has announced a series of initiatives on the nhs, today serves asa initiatives on the nhs, today serves as a bit ofa initiatives on the nhs, today serves as a bit of a reality check on the state of the service in england and the amount of pressure it is under. with a&e attendances, that's the numbers going through the front door of units in england, 2.27 million in

july, a record number up 4% on the same month last year. service chiefs are saying the heatwave was partly to blame for that increase injuly but lots of underlying factors as well. sometimes it's because people have lost faith with social care or gp services and end up in hospital which is not a good sign. and waiting targets are not being hit as well. yes, waits for routine nonemergency surgery such 3s a well. yes, waits for routine nonemergency surgery such as a hip replacement, so the figures forjune we re replacement, so the figures forjune were out today showing 4.4 million people overall waiting for routine operations. that's the highest number since these records began in 2007 and the numbers waiting more than 18 weeks has risen quite a lot as well. so that is a reflection of as well. so that is a reflection of a number of factors. sometimes hospitals don't have enough beds because of urgent cases coming in, enough beds to set aside for people needing routine surgery. the doctor's' pension tax row which

meant some doctors didn't want to do extra shift has affected things as well, but an example of the immense pressure on the nhs remains under. hugh pym, thank you. our top story this lunchtime: police have described a machete attack on an officer in east london late last night as "frenzied". a man in his fifties has been arrested. and fans of the beatles have been gathering in london to mark 50 years since one of the most iconic photos in pop music was taken. coming up on bbc news... the transfer deadline is approaching. tottenham look set to miss out on a big money signing, paulo dybala, but who else could be on the move? details on the way. india's prime minister, narendra modi, is scheduled to address the nation today as tensions rise over the disputed region of kashmir. it follows delhi's decision, to remove the territory's special status, revoking it's autonomy. in retaliation, pakistan has

suspended all bilateral trade with india. kashmir is claimed by both countries, and has proved a flashpoint for the nuclear armed neighbours over several decades. at present they both control part of the territory, with the indian administered region now in lock down, with hundreds of troops on the streets. naomi grimley reports. communications have been caught in india administered kashmir —— have been cut. at these images show how tensions have risen in the days since new delhi revoked this region's special constitutional status. the security services patrol the area, enforcing curfews in the eerie quiet. but stones and masonry scattered across the street are a tell—tale sign that angry protesters are making their voices heard when

they can. this was already one of they can. this was already one of the world's most militarised areas, and now since the sudden influx of more indian troops, things are at breaking point. translation: people of kashmir are angry, they are like a volcano which will erupt and india is unaware of the consequences. as well as anger there is uncertainty. this train station is rammed with migrant labourers who have got out of the kashmir valley, fearing serious violence is on the way. we have come from the kashmir valley, we don't have any money and my wallet is empty. we don't know how we will travel further as they are asking for tickets. the situation is very bad, a curfew is being imposed. our work has been disrupted. in the hindu part of this region, day—to—day life is continuing. later today the indian prime minister will

make a television address, arguing kashmir‘s status had to change to ensure the region kept pace with the rest of india on issues such as women's rights. but many kashmir people feel it is part of a hindu nationalist plan to change the demographics of the country's only muslim majority state. the un says it fears what might happen next in this already volatile area. we are seeing again blanket telecommunications restrictions, perhaps more blanket than we have ever seen before. the reported arbitrary detention of political leaders and restrictions on peaceful assembly. these restrictions will prevent the people of indian administered kashmir and their elected representatives from participating fully in democratic debate about the future status of kashmir. all of this when kashmir

has already witnessed decades of violence and insurgency, trapped between the rival territorial claims of two nuclear powers. naomi grimley, bbc news. police believe the search teams plan to play a recording of one of her family members on speakers to try to locate nora quorin, who disappeared 0h locate nora quorin, who disappeared on sunday in southern malaysia. british airways says it's now fixed the it glitch which caused more than 100 flights to be cancelled yesterday, and more than 200 others delayed. 0ur correspondent jon donnison is here. with all the british families trying to get away over the next few days for the summer holidays, this has been fixed now? it has, a horrendous day for thousands of customers

yesterday but today much better. we have had a statement from ba saying they are operating a normal schedule with some knock—on disruption. i have been looking at the departure boards for the main airport in london this morning. some delays, some cancellations, but pretty normal, nothing as bad as yesterday. the bad news is we have possible strikes coming up. ryanair pilots have announced two weekends of strikes coming up later this month and there is also the threat of strike action from ba and easyjet pilots and ground staff at heathrow and gatwick. all of this happening, as you say, at the busiest time of the year. thank you. engineers for network rail scotland, are trying to clear floodwater from the main edinburgh to glasgow line, after five trains became stuck last night. it happened after the drainage system was overwhelmed by torrential rain. katie hunter has more. wading through water on scotland's

busiest railway line. trains haven't been travelling here since last night. some passengers travelling between edinburgh and glasgow were stuck as the water level started to rise. rail replacement buses have been running from lithgow all day. i'm heading to london on the 12 o'clock train so slightly worried i might not manage to make it but they have assured me i will and if i don't i can get on the next train down. flash flooding caused trouble 0h down. flash flooding caused trouble on the roads too, but it is the rail network that has been worst affected. engineers have been at this tunnel all day trying to clear the water but progress has been slow. we have got teams on site really quickly and a series of pumps, pumping out the water. at one stage our water was two feet above the running rail so that is a really challenging volume of water in a

difficult place to access. we also have the fire brigade on hand to bring support and that water is starting to fall quickly now so we are hopeful we will be able to get in and inspect the track soon to make sure it is safe to reopen. higher capacity pumps are being brought in to try to clear the water, but scotrail says it is too soon to know when the line will be able to reopen. katie hunter, bbc news. fans of the beatles have been gathering in london to mark 50 years since one of the most iconic photographs of the band was taken. the picture showsjohn lennon leading the group over a zebra crossing outside the abbey road studios in north london, where most of their songs were recorded. the image is now one of the most famous in pop. lizo mzimba reports from abbey road. for half a century, fans from all over the world, fans of all ages have come here to recreate and, in

their own way, feel a connection to perhaps the most famous band ever. their own way, feel a connection to perhaps the most famous band everlj have come from belgium and i am here for thursday at abbey road because it is the last beatles recording. we are coming from mexico and it is special because we are fans of the beatles and we are excited to be here in london. we like the music.|j come from uruguay and the beatles are special and i like the music. 0ver are special and i like the music. over the years, abbey road studios became almost synonymous with the band, who recorded so much of their music there. they were the most famous band in the world but even they may have underestimated the impact those short few minutes would have, as they emerged from the studios there, came out on the road and at exactly 11:35am walked backwards and forwards over the

crossing while the photographer took six quick shots. the fifth was chosen and entered music history. the abbey road album is particularly special to the fans as it represents the last studio recording sessions to involve all four of the beatles together. half a century on, things we re together. half a century on, things were a little busier than that day in1969, were a little busier than that day in 1969, the police eventually having to intervene to control the fa ns having to intervene to control the fans blocking the road. and almost 50 yea rs fans blocking the road. and almost 50 years to the minute since the famous shot was taken, four members ofa famous shot was taken, four members of a tribute band recreated what has become an image that encapsulates what the beatles meant to so many. lizo mzimba, bbc news, abbey road. a footbridge connecting two halves of a medieval fortress at the legendary site of king arthur's castle is opening this weekend. hundreds of years ago, a narrow land crossing at tintagel castle in cornwall collapsed into the sea, leaving visitors with a steep climb if they wanted

to explore the site. the new bridge will reconnect the ruins, for anyone brave enough to walk the crossing. fiona lamdin has been to see it — and a warning, her report contains flash photography. for centuries, tintagel castle has been split in half, divided by the sea. but, for the first time since the middle ages, the island and the mainland have been reunited with a new footbridge. people can actually walk from the original entrance, through the mainland courtyard, across this bridge over into the island ward, where the great hall lies. it's about creating a sense of wonderfor people, and also for people to be able to understand the actual castle better. because they can actually progress through it, as our ancestors did. it's taken nine months to build the 70—metre bridge, using 47 tonnes of steel and 40,000 cornish slate tiles.

but it's actually not a new concept. if you go back to the 15th century, the castle was still one — joined by a narrow neck of land, before it eroded and fell into the sea. it's one of the most important places in britain for that period after the romans. there was a myth that this is where arthur was conceived, so it's very closely connected with arthurian legend. that's probably why richard, who was earl of cornwall in the 13th century, decided to build this later castle on this site. we're finding incredible stuff on this site. 0ver100 buildings — it was bigger than london, as far as we know, at the time. for the last 100 years, the only way of getting from the island to the mainland was this way — let's go. it's a 57—metre drop down to the sea. well, i've counted them. there's 272 steps and,

i can tell you, the last few are pretty steep. she exhales. i think it looks absolutely an amazing achievement, and i think it fits in really well with the landscape, actually. it'll be a lot more easier for the children. i mean, it's a lot safer, as well. if i brought my elderly mother along, then, yeah, definitely the bridge! this landscape has been without its crossing for hundreds of years. the earth and rock now replaced by steel, reuniting a divided castle. fiona lamdin, bbc news. you need a nice clear day to walk a bridge at that height! time for a look at the weather. here's ben rich. not to be recommended over the next few days, some extremely windy weather on the way.

this balloon festival got going early, organisers had an ascent earlier than planned this morning to make the most of the calm weather because that is not going to last. 0ver because that is not going to last. over the next few days expect some disruption. spells of heavy rain, gales in the forecast too and your local bbc radio station will keep you up—to—date. you can see on the satellite picture this beautiful swirl of cloud but it is an unusually deep area of pressure for the time of year and it is heading our way. at the moment we have the calm before the storm. some showers out there across scotland, northern england, northern ireland but many places dry with sunshine. but cloud gathering down to the south, and as we go through tonight we will see outbreaks of very heavy, for —— persistent, perhaps thundery rain moving into scotland by the end of the night, the wind is picking up as well. this is how we start off tomorrow. fine and dry across the
