the foreign secretary borisjohnson revives his contested claim that brexit could free up more money for the nhs. good evening and welcome to bbc news. detectives investigating the bomb attack on the london underground say they are keeping "an open mind" on whether more than one person was responsible for the bombing, despite arresting an 18—year—old man. 30 people were injured when it detonated yesterday at parsons green station. the man was taken into custody this morning in the port area of dover. the police believe the attack was motivated by islamist extremism. police have been searching a property in the surrey town of sunbury—on—thames. earlier this evening, they gave this update on the investigation. the metropolitan police

and its partners across the counter terrorism network have been working around the clock throughout the night to identify and locate and arrest those responsible for this cowardly crime. at approximately 7:50am this morning local police officers in kent arrested an 18—year—old man in the departure area of dover. he was arrested on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism. he's now been transferred to custody at a police station in london. officers from kent police had to partially evacuate the port of dover at around 11:1i0am this morning. and this was to enable them to search the premises as a precautionary measure. that work is now complete and they have recovered a number of items during that search. a short while later, again around 1:40pm, with the assistance of surrey police, met police officers also evacuated a house in sunbury on thames.

as a precautionary measure, we evacuated the surrounding buildings and set up cordons within a 100 metre radius. i want to reassure that community that our experts are quickly and thoroughly searching that address and we are working to ensure that it is safe. once this is done, a detailed search will take place, but i'd like to thank residents in sunbury and people travelling in and out of the port of dover this morning, for their patience and understanding while officers carry out this precautionary, but important work. deputy assistant commissioner neil basu of the metropolitan police giving that update there. in a moment we'lljoinjane hill and viewers on bbc one for a full summary of the evening's news. an 18—year—old man is arrested, suspected of planting the bomb on the london underground that left 30 people injured. he was taken into custody in the departure area of the port of dover,

which was partially evacuated. it is a very significant arrest. if there are other people responsible, it's ourjob to find them. that is part of the reason why we remain at critical at the moment. armed police are searching a house in surrey that's linked to the suspect. it's the home of a couple who provide foster care. she has fostered generations and generations of children. i've never known anyone more dedicated to the community and helping people. we'll have the latest on a fast—moving investigation. also tonight... four people have been killed, after a lorry crashed through the central reservation on the m5. a woman and two children are critically injured. ryanair cancels thousands of flights over the coming weeks, leaving some passengers stranded abroad. what a shot. and the west indies sets england a tough target in tonight's t—20

cricket match in durham. the police have described the arrest of an 18—year—old man in connection with the london underground bomb attack as very significant. he's suspected of planting the device, which detonated yesterday on a train at parsons green station, injuring 30 people. the teenager was taken into custody this morning, in the departure area at dover. this evening, police are continuing to search a house, linked to the suspect, in sunbury—on—thames. it's the home of an elderly couple who provide foster care. our home affairs correspondent daniel sandford is in sunbury. a significant section of this estate

had to be cleared of its residents this afternoon after heavily armed counterterrorism officers arrived to search one of the houses. some residents believe they heard a drone before the raid began. tonight, the house at the heart of the operation is still being pored over by forensic specialists. the hunt for the london tube bomber led this afternoon to this surrey council estate, and a mauve terrace house. fearing an explosion during their search, counterterrorism officers evacuated residents from several streets around the property. there could be a bomb down there, and they were telling me i could go into my house, even though there could be a bomb. i'm really scared. the couple living in the house being searched by the police, ron and pennyjones, are well—known for fostering teenagers, including refugees. they were even given mbes by the queen. she has fostered generations and generations of children.

i've never known anyone more dedicated to the community and helping people. itjust shows you, doesn't it, maybe after all these years she's a bit too trusting. even the best people can be made a fool of. the house was raided after police arrested an 18—year—old man in the departure area of the port of dover just before 8am this morning. the port also had to be partially evacuated. it was an arrest senior detectives described as very significant, and was the first sign of a major breakthrough. at this stage we are keeping an open mind around whether more than one person is responsible for the attack. and we are still pursuing numerous lines of enquiry numerous lines of enquiry and at great pace. it seems that the improvised explosive device at parsons green station, a bomb in a bucket, had failed to go off properly. that bag is on fire. but it produced a sheet of flame in the carriage. 30 people ended up in casualty, and three were still in chelsea and

westminster hospital this morning. but despite today's arrest, the official terrorism threat assessment in the uk is still at its highest level, with armed officers patrolling stations and busy venues like premier league football games. the threat level remains at critical, and there will be further investigations in part of the operation later today. we urge the public to remain vigilant but not alarmed, and we hope to come back with more news in due course. this has clearly been a good day for officers investigating the parsons green tube bomb, but they are not yet completely confident that the immediate threat is over. studio: daniel, how much do we know about the man arrested today? in terms of official information, very little. the police simply say they have arrested an 18—year—old man. from information that can be

gleaned from residents around the estate gives us some clues as to his likely identity. the elderly couple, penny and ron jones, likely identity. the elderly couple, penny and ronjones, who likely identity. the elderly couple, penny and ron jones, who fostered so many children here on this estate, was known to foster children from areas like the middle east and africa. residents here say there had been a couple of foster boys that have been living with them recently, one of whom had been in quite a bit of trouble, had perhaps been arrested in the parsons green area a week or two ago. the suggestion is that he was reported missing by penny and ron jones that he was reported missing by penny and ronjones on friday morning. that is the link, that this person who might have been reported missing by penny and ronjones, could have been the same man arrested in dover on suspicion of putting the bomb on the train. it's been quite as accessible 36 hours for the metropolitan police, having started with a smouldering failed bomb and some cctv images, they seem

to have their main suspect in custody, but we still have the threat level at critical, suggesting the police are not yet completely satisfied that they have all the people involved in this bombing in custody. daniel sandford in surrey. four people have been killed, and a woman and two children are critically ill in hospital, after an accident on the m5 motorway in gloucestershire. a lorry crashed through the central reservation, colliding with at least two cars. the motorway between almondsbury and falfield remains closed in both directions. jon kay has sent this report. horrific and harrowing — the words from police tonight to describe the m5 crash. the motorway was busy when the lorry smashed through the central reservation into three lanes of oncoming traffic, hitting at least two other vehicles before ending up in a ditch. as well as the four people who died this afternoon, a woman and two children have life—threatening injuries. the lorry driver was taken to hospital as a precaution.

eyewitnesses have told us that as soon as the accident had happened, people abandoned their cars on the carriageway and ran to the scene to help out, with those who were medically trained offering first aid to the injured. there was a senior gp, myself as a cardiologist. we scanned the area to see who was affected. we found the truck driver, who was ok, but someone was trapped in the car itself. and then we went to see the other people. there were two fatalities at least in the first car. there was loads of cars on the right—hand side, loads of people helping out, but itjust looked like, when we got out of our car, it was clear that it was standing still.

itjust looked like pandemonium, but loads of people helping out. loads of blues and twos came down. they were amazing. police praised the courage of those who helped and have asked for patience while they investigate and clear the scene. the m5 is the main route between the midlands and the south—west of england, and the crash has led to long delays and diversions. although a small amount of traffic has been allowed past the night, the motorway is expected to remain shut in both directions for several hours. jon kay, bbc news, south gloucestershire. ryanair is facing a wave of complaints after announcing it is cancelling up to 50 flights a day for the next six weeks. the move could affect hundreds of thousands of people. some passengers who've already flown abroad with ryanair, have been informed by text that their flight back to the uk has been cancelled. our business correspondent joe lynam reports. it's europe's busiest airline, but it's grounding hundreds of its own planes. in doing so, it's ruining holidays for thousands of its own customers, some of whom are now stranded overseas. carrie—ann woodgate is in poland

and was e—mailed by ryanair. the next flight out of here is next thursday. we can't get through to anyone at ryanair, we can't get through to a manager, live chat doesn't work, the app doesn't work. if you do ring ryanair on customer services, all you get is, "we're having a very large volume of calls." you betcha! others have had to cancel their holidays. they text me the evening before the morning i was supposed to fly, so, yeah, pretty disappointed. lost a holiday out of it, and lost some money as well. ryanair says that air traffic control issues and weather, as well as a surge in pilots and cabin crew taking their holidays, is forcing it to ground up to 50 flights a day until the end of october. but that's still only 2% of the airline's entire flight schedule. but passengers set to fly with ryanair in the coming weeks simply don't know whether their flight will actually take off. it could be cancelled right up to the moment they arrive in the airport. the spin that ryanair is putting on this is saying, we want to make our timekeeping better, so we're putting more planes on the ground in case

something goes wrong. i must say, from the passengers' perspective, someone like me who has got a booking on ryanair in the next few weeks, that looks like total tosh. basically, it's a massive administrative foul up. all their cabin crew and pilots are taking their holidays before the end of the year. so, what could you get back if you're affected? eu rules say you are entitled to a new flight or full compensation if your flight is cancelled. the airline also has to cover your food and accommodation if you're stranded, and it should offer to pay for a flight with a rival airline if it can't get you on another flight to your final destination. all this means that these cancellations could cost ryanair‘s enigmatic boss michael 0'leary up to £100 million. it's difficult to put a price, though, on damage to the airline's reputation. joe lynam, bbc news. borisjohnson has renewed the controversial claim that britain will save £350 million a week, by leaving the eu, which could be spent on the nhs.

the foreign secretary set out his vision of what he called britain's "glorious future" after brexit, in a newspaper article. labour and the liberal democrats said government divisions had been laid bare, and accused mrjohnson of plotting a challenge to theresa may's leadership. 0ur political correspondence alex forsyth is with me. why is he saying it now? this is a significant intervention, a long and in—depth article in which borisjohnson makes the case for a bold and thriving brexit. most controversially he does repeat the claim that leaving the eu will free up £350 million per week, despite that figure being widely discredited. 0n the brexit bill he says the uk must settle its accounts but shouldn't pay to access to the customs union and single market. he makes no mention of a transition deal. many are seeing this as a direct challenge to theresa may's authority and it's causing some anger in the tory party. but those close to borisjohnson say it's not about that at all, he's just making

the case for a positive brexit. he's tweeted to say he's behind the prime minister, but he knows it will play out well with tory brexiteers, those who think the current leadership lacks vision, and it comes less than a week before the prime minister is due to give a big speech of her own on brexit. so there are plenty who think this isjust on brexit. so there are plenty who think this is just as much about boris johnson's think this is just as much about borisjohnson‘s political future as it is about the future of the country. alex forsyth, thank you. in syria, russian troops have taken control of the eastern city of deir al—zour, forcing out so—called islamic state. the city had been held by is for three years. it's in retreat as president assad regains territory with his allies. the bbc‘s steve rosenberg is the first british journalist to enter deir al—zour since is was driven out. on a russian military helicopter, we are heading east across syria. we are escorted by two gunships in case we come under attack. eventually, we arrive in deir al—zour, a city only starting to recoverfrom a nightmare.

for three years, this part of town was cut off from the rest of the world, surrounded by is fighters. well, with the help of russian air power, the syrian army broke that siege just a few days ago. now people here tell us that is militants have been pushed back around three miles. but security is still a concern. russian special forces accompany us to the market. the syrian soldiers here, well, they're a little more relaxed. supplying the city with food and drink and medicine is easier now. during the siege, deir al—zour had to rely on humanitarian aid by air. thanks to god, thanks to the syrian army and the russian army, this man says, syria is victorious. there is still fighting in deir al—zour, but the syrian army has reclaimed much territory

in and around the city. this oil—rich region was the heart of islamic state's economy. defeating is here would be a major victory for president assad. life may be returning to this city, but there's still danger here. steve rosenberg, bbc news, deir al—zour. now with all the sport, here's john watson at the bbc sport centre. england and west indies are contesting a one—off twenty20 cricket match in durham. the big hitting chris gayle, one of the great limited overs batsmen, has pulled in the crowds at chester—le—street. adam wild reports. the english cricketing summer may well be coming to an end, but in darkening durham, there was little warmth still to be found. but nobody likes of this form of the game quite likes of this form of the game quite like chris gayle. when he arrives fashionably late in the season, everybody takes notice. these west

indies players were not involved in a recent test series. still, it didn't take long to show they had arrived now. chris gayle scoring quickly, yes, but rarely hurried. here it cost him. run out, a big moment for england. 0thers followed his lead. those september skies were attempting target. the west indies 176 was the worry. it wasn't eased any when jason roy fell on the first ball. alex hales fared far better, battering a3. that was enough to offer england hope but it appeared fleeting. key players now coming and, crucially, going. a late night in durham with england left with plenty to do. adam wilde, bbc news. play still underway, england requiring 2a from 5 balls for victory. i suggest looking away now if you don't want to know the premier

league results. former england manager roy hodgson suffered a defeat on his return to football. his crystal palace side lost 1—0 to southampton becoming the first top flight team to lose their opening five league matches without scoring a goal. sergio aguero grabbed a hat—trick as manchester city a hat—trick as manchester city beat watford 6—0, to move to the top of the table. they've scored a total of 15 goals in their past three matches. newcastle moved into the top four with their third successive league win, beating stoke 2—1. philippe coutinho made his first start of the season but couldn't prevent liverpool from being held at home to burnley. the remaining matches also finished in draws. celtic moved clear at the top of the scottish premiership with a a—0 win over ross county. second placed aberdeen were held at home to bottom of the table kilmarnock. while there were wins for dundee and hearts. and the 3—1 favourite capri, ridden by ryan moore, has won the world's oldest classic, the st leger. the grey battled down the straight ahead of crystal 0cean and stradivarius to give trainer aiden 0'brien his fifth triumph in the race. the victory means jockey ryan moore has now won all five of the british classics.

and lewis hamilton says he needs a miracle if he's to limit the damage to his title chances as he starts from fifth on the grid for tomorrow's singapore grand prix. rival sebastien vettel is on pole. you can read more on that on the bbc sport website. that's all the sport. that's all from me. goodnight. good evening. saturday was a mixed sort of day. we had some long spells of sunshine but equally some pretty heavy showers and the hello. this is bbc news. north korea's leader kimjong un has said his goal is to match the military power of the united states. his comments come after the united nations security council described the latest missile test overjapan as highly provocative. washington has again warned pyongyang of possible military action. but russia and china say diplomacy is the only solution. stephen mcdonnell reports from seoul. north korea has released footage which it says is of its latest ballistic missile test,

the day after it was carried out. also images of an elated kim jong un, present at the site. the country's state media has quoted their leader as saying "this was to achieve equilibrium force, so that the us would not even talk about a military move against his regime". across the pacific, washington is considering its next move. we've been kicking the can down the road and we're out of road. so for those who have said and been commenting about the lack of a military option, there is a military option. it's not what we would prefer to do. we call on all nations to do everything we can to address this global problem, short of war. when the us administration talks about everyone, that really means china.

yet beijing says it's the americans who are not upholding their end of the un sanctions bargain. translation: the un resolution also calls for reopening dialogue and resolving the issue through consulations. the resolutions should be implemented fully. meanwhile, with no solution in sight, the public in south korea and japan are left wondering what their futures might hold. in both countries, it's not only the hawks who are considering if they are being adequately protected from a nuclear armed neighbour. here in seoul, not surprisingly, the current crisis is dominating politics. there's an opposition party petition being circulated, in an attempt to create ten million south korean signatures calling for the reintroduction of tactical nuclear weapons here. the government says this willjust inflame the situation here. and increase this threat to the country's citizens. and just one hour's drive

away, north korea says it is close to reaching full nuclear capability. a koala has been rescued after it crawled into the wheel arch of a vehicle and went on a ten mile journey. the female was found clinging to the axle of a a—wheel drive after the driver stopped and heard her cries. the wheel had to be taken off to free the animal, but it was uninjured and after a few days of resting and feeding in captivity, it was released into the forest. there she goes. not too troubled, hopefully. time for a look at the weather with sarah keith lucas. good evening. saturday was a fairly mixed sort of day. we had some long spells of sunshine but pretty heavy showers and that combination of sunshine and showers meant there was plenty of rainbows around.

this was earlier on in royal leamington spa in warwickshire. we've got those clear spells and still a few heavy showers, certainly over the next few hours. but our weather is really dominated by the fact low pressure is sitting out to the east at the moment. high pressure in the south—west. that leaves us with this northerly flow of air. so fairly cool conditions developing tonight. not particularly windy. and as the showers fade we will see them continuing in the south and south—west. clear spells across many parts of the country but light winds and clear skies, that means quite chilly conditions. during the early hours of sunday in our towns and cities, temperatures still around eight to 11 degrees. but it will be colder than that in the countryside, a touch of frost across parts of scotland, northern england and northern ireland. after that, a fresh start to tomorrow with a bit of mist around and it will be an improved day. fewer showers than we saw on saturday and more in the way of sunshine. so you could wake up to quite a chill in the air first thing with mist patches. still showers during sunday morning, particularly around the south coast, the channel islands, the south east. they should ease away but then more

widely across england and wales, seeing the odd rogue shower popping up through the afternoon. but many avoiding them, particularly in scotland and northern ireland, mostly dry here. we could see temperatures up to 18, possibly 19 degrees in sheltered spots. not a bad day. many of those isolated showers tend to fade away into the evening hours so we end sunday on a mostly dry note. but we've still got the low pressure sitting out towards the east and higher pressure further west, so a northerly flow to the air as we move through into monday. and that means particularly around the east coast where we draw in the breeze, there will be one or two showers. but most places having a largely dry day monday with some long spells of sunshine. and in the relatively light winds away from the east coast, it should feel relatively generally pleasant around 15 to 17 degrees. a touch cooler for the likes of newcastle, up towards aberdeen as well.

tuesday, mostly dry, bit of a breeze in the east. just one or two showers but most staying dry with those temperatures up to around 1518 degrees. bye for now.
