The hunt for the london tube bomber led this afternoon to this Surrey Council estate, and a mauve terraced 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. Im really scared. The couple who live in the house being searched by police, ron and pennyjones, are well known for fostering teenagers, including refugees. They were even given mbes by the queen. Shes fostered generations and generations of children. You know, and ive never known anyone more dedicated to the community, and helping people. Itjust shows you, doesnt it . Maybe shes, after all these years, a little 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 8 00am 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, were 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 bags 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 todays 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.

Lets go to bangladesh now, where the government is planning to build a giant camp for the 400,000 ethnic rohingyas who have fled from neighbouring myanmar. The government says it will also impose restrictions on the movement of the rohingyas, in order to prevent them from settling in other parts of the country. 0ur South East Asia correspondent Jonathan Head has the latest from coxs bazar. When they first started crossing the border, three weeks ago, bangladesh said it would send the fleeing rohingyas back. With 400,000 already here from previous outbreaks of violence, the government believed it could not take any more. But the unprecedented surge in numbers of rohingyas has forced bangladesh to reconsider. It now wants to build a vast camp, adjoining an existing one, in which it hopes to accommodate all 400,000 of the new arrivals. The police say they will also enforce restrictions, barring the rohingyas from moving elsewhere. There are questions, though, over how fast this can happen. The displaced rohingyas are in desperate need of the most basic aid. They are, in many cases, sleeping in the open, with no sanitation or water supplies. Until now, the Un Refugee Agency has been restricted to the relatively small numbers, around 70,000, living in official camps. Un officials hope that the government will now consider a wider role for various un agencies, so that a full scale relief effort can be organised. Jonathan head, bbc news, coxs bazaar. The United Nations has called for an investigation into the killing of burundian refugees in the east of the democratic republic of congo. The un force in congo says the Congolese Security forces shot dead 37 refugees and injured 117 others. It said one soldier was killed in the incident, which began when the refugees protested against the expulsion of four burundians from the country. Andrew plant reports. The bodies of burundian refugees, apparently killed when Security Forces opened fire. Officials in the democratic republic of congo say the refugees were attempting to break into a secure compound. This camp, just a few mails from the border of burundi, now home to thousands who fled outbreaks of violence in their country, which erupted there more than two years ago. Translation the Security Forces in the democratic republic of congo threatened to kill us, in case we did not want to return home to burundi. Justice must be done. Many more have been injured in the violence at the camp. Basic medical care given at the side of the road. Opponents of burundis president , pierre nkurunziza, say his move to stay in office for a third term in 2015 was illegal. The clashes that followed caused tens of thousands to flee, opposition rallies crushed, with rumours of abductions and torture. In france, regular demonstrations are taking place to try to draw International Attention to burundi, and a situation that many say could escalate into civil war. Translation there are people dying every day it burundi, and they close their eyes. So perhaps were there to move them a little, perhaps to open their eyes, they are trying to close. Its very, very hard. The government says the People Killed were members of an armed group who had attacked an office of the National Intelligence agency. The Un Refugee Agency has called for a full investigation, and has sent medical teams to help treat more than 100 who have been injured. A demonstration has been held in central barcelona in support of over 700 catalan mayors who backed a referendum on regional independence. The leaders have been summoned by spains public prosecutor, and will be arrested if they dont answer the summons. Here is our europe regional editor danny aeberhard. We will vote the chant from 700 mayors and their supporters, gathered inside the gothic courtyard of catalonias palace of government. They have come to the administrative heart of old barcelona. There, they were met by crowds waving the Pro Independence flag, and were received by both the citys own mayor and the regions president. Those in madrids sights hammered home messages of defiance. Translation were sure that we wont be cowed. We wont remain still. Well do everything necessary so that our people, the people we see every day, can exercise democracy and can vote. Long live catalonia. The spanish governments dilemma how to stop a referendum that polls suggest a clear majority of catalans want, even as they indicate that the odds are against independence. Prime minister Mariano Rajoy has vowed to thwart what he has called an intolerable act of disobedience. But come down too heavily, and it risks playing into the hands of the secessionists. The dilemma for the catalan authorities how to stage such a referendum, in the face of madrids implacable opposition. This goes beyond legal threats and efforts to seize election materials. Madrid looks set to take control of the regions finances next week. The referendum is planned fori 0ctober, two weeks away. So far, neither side is backing down. Lets take a look at some of the other stories making the news police in the us fired tear gas and rubber bullets during clashes with protesters in st louis earlier on saturday, after a white former policeman was acquitted of murdering a black suspect. A peaceful rally over fridays not guilty verdict turned violent after police confronted a group of demonstrators. More than 1,000 people have demonstrated in the tunisian capital, tunis, against a controversial amnesty bill that was approved by parliament on wednesday.

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 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 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, and a registrar, and myself, as a cardiologist. We scanned the area to see who was affected. We found the truck driver. He was ok, but his legs was stuck in the car itself. And then we went to see the other people. There was 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 cars, it was clear 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 tonight, the motorway is expected to remain shut in both directions for several hours. Jon kay, bbc news, south gloucestershire. Passengers have reacted with fury after rya nair announced it was cancelling up to 50 flights a day for the next six weeks. The airline says it needs to improve punctuality and deal with a backlog of staff leave. The move could affect nearly 300,000 passengers. Our Business Correspondent joe lynam reports. It is europes busiest airline, but it is grounding hundreds of its own planes. In doing so, it is 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 cant get through to anyone at ryanair, we cant get through to a manager. Live chat doesnt work, the app doesnt work. If you do ring ryanair on customer services, all you get is, were 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 out. 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 thats still only 2 of the airlines entire flight schedule. But passengers set to fly with ryanair in the coming weeks simply dont 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 therefore, were 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 is a massive administrative foul up. All their cabin crew and pilots are taking their holiday before the end of the year. So, what could you get back if youre affected . Well, 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 youre stranded, and it should offer to pay for a flight with a rival airline if it cant get you on another flight to your final destination. All this means that these cancellations could cost ryanairs enigmatic boss, michael 0leary, up to £100 million. It is difficult to put a price, though, on damage to the airlines reputation. Joe lynam, bbc news. Earlier i spoke seth kaplan, manager of commercial aviation Magazine Airline weekly. I asked him how damaging this was to ryanair and the Budget Airline industry. Well, its very damaging to both, to ryanair in particular, as well as the industry. There was a time, for most of rya nairs history, where it was like, as long as it was cheap, that was all that had to be. It thumbed its nose in the face of customers. But this has changed. To expand its market, it needed to appeal to people who want something more than just a cheap fare. Its been touting itself as being friendlier to customers. And, although this has always been a no frills airline, it always had a rather good operational reputation. That was one thing that it always did rather well it was on time. So once its punctuality stars to be affected, this is indeed quite damaging. One can begin to understand, possibly, the change in the laws about when cabin crew and pilots needing to take their leave, and that has caused disruption. Perhaps one can understand different things. But to announce and give passengers so little time, what was the reason for that, do you think . Clearly, they were trying to piece things together. They must have felt that they had a solution, or were close to one, before realising the numbers dont add up. It is not unprecedented in the history of commercial airlines. I can think of other examples Legacy Airlines like ba, where they realised they didnt have enough time left. But ryanair sort of almost didnt have a lot of goodwill built up with its customers. They were trying to change that. But for them, more than most right now, they have invested so much in trying to change the reality, and then it takes some time for perception to catch up to the reality. Ryanair are a successful airline. This will create an existential problem for ryanair. It will be fine, financially, but not the news they want. This is bbc news, the headlines this hour police have arrested an 18 year old man on suspicion of a terror offence following fridays bombing on a london tube train. Bangladesh is imposing wide ranging restrictions on the movement of more than 400,000 Rohingya Muslim refugees who have fled myanmar in recent weeks. The bbc understands that the Prime Minister does not plan to sack borisjohnson after a newspaper article which some senior politicians say exposes a split at the top of the party. In the article, the foreign secretary set out his vision of what he called britains glorious future after it leaves the eu, just six days before theresa may is due to give a speech on her blueprint for brexit. 0ur Political Correspondent alex forsyth says its a significant intervention by boris johnson. This is a long and in depth article on which borisjohnson is making the case for a bold and thriving brexit. Controversially, he repeats the claim that the brexit will free up £350 million a week. Despite that being discredited widely. He makes no mention of a transition deal. Many are seeing this as a direct challenge to theresa mays authority, which is causing some anger in the tory party. But those close to borisjohnson say it isnt about that at all, he is making the case for a positive wrecks it and he has tweeted to say he is behind the pm. But he knows this will play out well with tori brexiteers, and this comesjust well with tori brexiteers, and this comes just 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 is a this is just as much about borisjohnsons political future as it is for the countrys future. The british super model kate moss has been heckled by hundreds of anti fur protesters outside a fashion show in london.

Paraathlete steve brown, a former wheelchair rugby captain, has been to meet a fellow athlete whos determined not to let a life changing injury hold him back. 0bviously that was the vehicle was in petroleum. I was found 20 or 30 feet away, face down. Im still here, still moving. Stuart robinson graduated from the raf one day after his 18th birthday. He proudly served his 18th birthday. He proudly served his country in Northern Ireland, iraq and afghanistan. However, his life was changed forever when his vehicle drove over an improvised explosive device, or ied, while on a routine patrol in helmand province, in 2013. My only overriding memory of that whole time was the fact that because i could still see i was still alive. And that moment that your wife and yourself locked eyes, that must have been quite a moment for her as much as for you . She knew that when she saw me for the first time in hospital that despite the injuries and the number of limbs i was missing at the time, she knew it was missing at the time, she knew it was me. I was walking about when i got out of hospital, trying things and ive used the Invictus Games as and ive used the Invictus Games as a massive tool to get on the road. It isa a massive tool to get on the road. It is a process i know well. After i was injured 13 years ago, i was introduced to wheelchair rugby and eventually captained gb paralympic tea m eventually captained Gb Paralympic Team at london 2012. Its crazy to think that you watched me play in 2012 as captain. And now you are there, Invictus Games captain, going onto your second as well. There, Invictus Games captain, going onto your second as welllj there, Invictus Games captain, going onto your second as well. I know. Like i said, it was great to watch you guys play and i think maybe subconsciously it might have kickstarted that fire within the play the sport and obviously just difficult circumstances led to actually playing it. More than 300 people applied to join the uk squad. Thats the biggest number since prince harry founded the games in 2014. I think 2014 was a really exciting opportunity. We had no idea what it would be, what the outcomes would be and how it would grow and i think what weve seen over the last three years is that the public appetite for what we are doing and such an interest from the people and really positive recovery impact. Stuart was part of the team that won bronze last year in orlando and now he has the chance to serve his country again and he wants to do even better. Steve brown there. In australia, a koala has been released back into the wild after enduring a 16km nightmare, clinging onto the axle of a four wheel drive vehicle. Incredibly, she was unharmed, as tom donkin reports. How much can a koala bear . Well, quite a lot, it seems. This koala in the southern australian city of adelaide held on for dear life to the axle of the moving car for 16 frightening kilometres. The curious marsupial had snuck behind the wheel of a parked car, which took off with her still inside. It was only when the driver heard the panicked cries of the inadvertent stowaway that it was discovered. I have never seen anything like that and it is absolutely incredible. She was crying a little bit, she was shaken. Certainly in shock. But i rushed her straight to the vet. Rescuers had to remove the wheel of the four wheel drive to free the animal. Luckily, apart from some burnt fur, no real harm was done. After a period of rest, she was taken far away from traffic and back to the trees. Happy to put the brakes on her driving days. China is a country that is advancing at an extraordinary pace. It has one of the largest economies in the world and its taking an ever greater role on the global stage.

The organisers hope this sort of innovation can help transform the economy. 0ne kung fu robot at a time. The weather now, with sarah keith lucas. Hello there. The second half of the weekend should bring us a decent day across most parts of the country. It could be quite a chilly start to the day on sunday, with some mistiness around. Later on, sunshine. A few showers, but not as many showers as on saturday and not as heavy as they were, either. Low pressure still sitting to the east of the uk. Higher pressure moving in from the south west from the atlantic. That leaves us with a cool northerly breeze, particularly eastern scotland and north east england as well. Most of the showers on sunday morning will be concentrated across southern england. Across much of the rest of the country, quieter. Some heavy showers towards the channel isles. There could be a rumble of thunder. Inland, most places dry with clear spells. One or two patches of mist first thing across england and wales. Perhaps the chance of an isolated shower for north east england. For much of Northern Ireland and scotland, a dry and bright start. But a chilly start. But things will warm up relatively quickly once the sun gets going. A cool breeze across parts of eastern scotland and north east england, which could dry in a few isolated showers. Most places staying dry for a good part of the day. But during sunday afternoon, a rash of showers developing. They will be hit and miss, so for many parts of the country, you will avoid the showers altogether, particularly further north and west. But we could see one or two showers towards the east. If you do catch one, it should pass through relatively quickly. During sunday evening then, any of those isolated showers will largely fade away, leaving us with a mainly dry night. But you will notice that breeze continuing in the east coast of england, drawing in one or two showers across the north sea. With clear skies and light winds elsewhere, a cold night. By first thing monday, temperatures will be a few above freezing in some rural areas, so a cool start to the working week. Monday, low pressure in east and High Pressure in the west. So thatll bring largely dry weather across the country on monday. But with that northerly breeze feeding in once again, that could bring a few showers to eastern scotland and england. Further inland, one or two isolated rogue showers popping up. Most of us avoiding them. Many of us, the weather will be dry and bright. Temperatures 17 or 18 degrees in the south, but cool for newcastle and aberdeen. Into tuesday and wednesday, a bit of rain for the middle of the week, but the temperatures are on the rise. This is bbc news. The Headlines Police in britain say they are hunting for more potential suspects after an 18 year old man was arrested, suspected of planting a bombing device on a train on friday.
