this is bbc news. i'm martine croxall. the headlines at 11. police say the terror threat level remains "critical", after they arrest a man at the port of dover in connection with yesterday's attack at parsons green. it's a very significant arrest. if there are other people responsible it's ourjob to find them — and that is part of the reason why we are remaining 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's fostered generations and generations of children and i've never known anyone more dedicated to the community and helping people. four people have been killed, after a lorry crashed through the central reservation on the m5. a woman and two children are in a life—threatening condition. also in the next hour, some passengers are left stranded abroad after ryanair implements a programme of flight cancellations. the airline says it plans to axe up to 50 services a day for the next six weeks to clear a backlog of staff leave. and we'll be talking a look

at tomorrow's front pages, including the observer which focuses on the investigation into the bomb attack on the london underground. good evening and welcome to bbc news. the police have described the arrest of an 18—year—old man in connection with the london tube attack as very significant. they say they are keeping "an open mind" on whether more than one person was responsible for the bombing. the 18—year—old is 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. police have been searching 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 reports from sunbury on thames 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 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. daniel sandford, bbc news, sunbury—on—thames. four people have been killed, and a woman and two children are critically ill in hospital, after an accident on the m5 in south gloucestershire. a lorry crashed through the central reservation, colliding with at least two ca rs. 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 his legs 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 o'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 reviewed the controversial claim that the uk will save £350 million a week by leaving the eu, which could be spend 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. our political correspondent alex forsyth says it is a significant intervention by borisjohnson. this is a long and in—depth article on which borisjohnson is making the case for a bold and thriving brexit. co ntroversially case for a bold and thriving brexit. controversially he repeats the claim that leaving the eu will free up 350 million a week. on the brexit till he says the uk must settle its accou nts he says the uk must settle its accounts but should not pay for access to the customs union and

single market. he makes no mention of the transition deal. many see this as a direct challenge to theresa may, and that causes anger in the tory party. but those close to borisjohnson say in the tory party. but those close to boris johnson say that in the tory party. but those close to borisjohnson say that is not the case at all and he is just making the case for a positive brexit. he knows this will pay our well with tori brexiteers, those who think the current leadership lacks vision, and this comes less than a week before the prime minister is due to give a big speech of her own on brexit. there are plenty who think this is just as much about borisjohnson‘s political future, as it just as much about borisjohnson‘s politicalfuture, as it is just as much about borisjohnson‘s political future, as it is about the future of the country. the united nations says more than 400,000 refugees are now known to have arrived in bangladesh from neighbouring myanmar in the last three weeks. bangladesh, which is struggling to cope with the influx, has said it will build a massive camp to house the refugees — and plans restrictions to prevent them settling in other parts of the country. in syria, russian troops have taken control of the eastern city of deir al—zor, forcing out so—called islamic state fighters. the city had been held by islamic state for three years.

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. north korea's leader kimjong—un has said his goal is to match the military power of the united states. his comments come after

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 collect 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. we'll have a full paper review at 11:30 but first, let's have a quick look at some of the front pages. the observer leads on the news that an eighteen—year—old man is being questioned by counter—terrorism police in connection with the parsons green attack the mail on sunday reports that theresa may's allies have accused boris johnson of treachery after he staged an open revolt over her plans for a ‘soft‘ brexit. the sunday telegraph claims that cabinet ministers, michael gove and priti patel have thrown their weight behind the foreign secretary's vision for brexit.
