man at dover in connection with yesterday's bombing of a london underground train. armed police and military personnel are being deployed at key locations across the uk, following the raising of the terror threat level to critical — the highest possible alert. in the past half hour, there have been reports of an armed police operation at sunbury on thames in surrey, by officers investigating the parsons green attack. the two locations are around 11 miles apart by road. earlier an 18—year—old man was arrested in dover and detained on suspicion of being a terrorist. the home secretary has described the arrest as very significant. 0ur correspondent robert hall is at new scotland yard. plenty of investments? yes, when

senior officers came out this morning and made a brief statement about that arrest in dover, they also used the words that the public should expect further police activity and that indeed has happened in the last hour or so. we began getting reports from local residents initially of this police operation in sunbury. it's, i suppose, to people who don't know the area, it's a suburb of london. it's close to the river thames. certainly accessible to the district line, which runs through parsons green which is where that device was planted yesterday. my colleague has been looking at events and the developing situation. can you bring us developing situation. can you bring us up to speed. i know it's very fluid. but broadly speaking, what do we know about what's happening there? we know that armed counterterror police have been on the scene since i. counterterror police have been on the scene since 1. 30pm. sunbury on

thames is a residential area, a few miles south of heathrow airport. they say they began evacuating the address at i. they say they began evacuating the address at 1. 40pm, they say they began evacuating the address ati. 40pm, it's they say they began evacuating the address at 1. 40pm, it's a precautionary measure following the arrest this morning. we understand approximately 80 officers involved, significant. surrey police are helping with the operation. 400 people have been evacuated from the local area. there's a 100—metre cordon in place. the initialfocus in parsons green, then to the port of dover, now a third location where this very fast moving operation is centred as counterterror officers evacuate a large area and investigate what may be at this residential address. we saw this yesterday with the train when they began to move what they believed to began to move what they believed to be the device itself from the train. they had to evacuate an area there. there's a concern with public safety. they have to be really careful. absolutely. who knows what they might find, what intelligence they might find, what intelligence they might find, what intelligence they might have gathered either from they might have gathered either from

the discovery of the device or having questioned this 18—year—old they arrested this morning in this address in sunbury, in the south pa rt address in sunbury, in the south part of london not a million miles away from where we saw this device being planted. we are looking at early pictures now of i believe police on the scene. i believe initially from people in the area at the time. just one thing which we have heard. police sources are telling us that they believe that the person that they arrested in dover was the person that planted that bomb. of course, that presumably is as a result or they may have drawn that conclusion from the evidence that they've been looking at overnight and through yesterday. yeah, they might have seen what has been found since they evacuated a few hours ago and got into this residential address. they will gain lots of information from that address and speak together person they are questioning, this 18—year—old arrested at the port of dover this morning. we also know the device that was removed from the train has been, that was removed

late last night, that's been investigated by fron sick officers for nearly —— investigated by forensic officers for nearly 24 hours. thank you very much indeed. sticking with that arrest, it happened in dover. initially by kent police. the individual concerned was held in a police station there. was due and may already have been brought up to london to be held in a london police station to be spoken to by counter—terrorism officers. so we don't yet know whether that operation has happened. but we expect that possibly to be part of a police statement later on this afternoon. 0ne police statement later on this afternoon. one other small update relating to casualties, we now have a figure of 30 casualties that went to hospital yesterday. some of them by ambulance. some of them took themselves to casualty for treatment, all but three have now been released from hospital. just three people still receiving treatment. it has been a fast moving day. i referred to it at the top of this report. so let'sjust

day. i referred to it at the top of this report. so let's just go day. i referred to it at the top of this report. so let'sjust go back day. i referred to it at the top of this report. so let's just go back a little, look at what's been happening with the help of my colleague daniel sandford. the port of dover this morning, where an 18—year—old man was arrested by kent police on suspicion of terrorism. an arrest detectives described as "significa nt, " and which is directly linked to the investigation into yesterday's explosion on a west london tube train. the arrest is the first obvious breakthrough. nobody died when the improvised explosive device produced a wall of flame in the carriage. that bags on fire... the home—made bomb in a bucket, which detectives believe is linked to islamist terrorism, appears to have failed to detonate fully, but 30 people ended up in casualty. three of them are still being treated at chelsea and westminster hospital, and last night the uk moved to its highest terrorism threat level — critical — and soldiers were deployed to do some of the work of armed police officers. we have authorised 0peration temperer, which is the initial

deployment of a number of troops. they will be deployed to key sites in the uk to free up armed police. and so you will see more armed police on the streets, up to between 500 and 1,000 depending on how the police wish to deploy them. at euston this morning the change in threat level was immediately obvious, with more armed officers patrolling the station. there are seven premier league football matches today and there will be higher security at all of them and at all big public events. we have our go critical plan. we've ta ken we've taken a series of measures in london today and yesterday. we have more police on the streets. we have more police on the streets. we have more unarmed police and more armed police. the public should feel utterly reassured by that. i've been out and about today. the public seem to be very positive about the number of officers that we have here. the bbc understands detectives have good cctv images of the person suspected of planting yesterday's bomb. officers say they are pleased with the investigation‘s progress. london's mayor siddique khan said that the city will never be

intimidated by terrorism, and we will always defeat those who seek to destroy our way of life. daniel sandford, bbc news. away from the actual investigation, the government's emergency cobra committee has been meeting to be brought up to date with developments, to be given a feel for it, and also to reach a decision on whether or not to maintain the current critical state of alert, thatis current critical state of alert, that is an imminent threat remaining a possibility. that meeting lasted 45 minutes. our political correspondent was there when it broke up and this is what she told me earlier. we know that the meeting of the cobra emergency committee has now ended. it was taking place here at the cabinet office in whitehall. it's the second meeting since the explosion and today, it was chaired by the home secretary, amber rudd. theresa may, who chaired the meeting yesterday, in the immediate aftermath of the explosion is now

backin aftermath of the explosion is now back in her constituency. though she is being kept updated on developments. because of the significant movement in the investigation this morning, there will have been some discussion about that progress in the investigation and of course consideration of the threat level, raised to its highest level last night, when the suspected bomber, the person who planted the bomber, the person who planted the bomb on the train was believed to be at large. of course, we've had this arrest. we don't know if that is the end of the story. there will have been discussions about the threat level and whether that should be reduced again back to the level it was yesterday, one below the critical, which meant an attack could be imminent. we are expecting to hearan could be imminent. we are expecting to hear an update further about what was said in the emergency committee meeting this afternoon from the home secretary, amber rudd later today. ijust want secretary, amber rudd later today. i just want to bring us secretary, amber rudd later today. ijust want to bring us a bit of context, bit of an outside look at

what is going on. we can speak to dal babu, who is a former chief superintendent of the metropolitan police. can you hear me? i can, yes. obviously, things are moving very quickly. i expect you've been listening to what's been happening in the last hour or so. there were references earlier for the public to expect further police operations. this really is moving quite quickly. that's right. i think yesterday we saw the assistant commissioner in charge ever counter—terrorism being very reluctant to give any details and clearly there was a reason for that, because they had significant amount of intelligence which they plan to act on and we'd been told that the raid on the address in surrey was done at i that the raid on the address in surrey was done ati pot that the raid on the address in surrey was done at i pot 30. that the raid on the address in surrey was done ati pot 30. so —— surrey was done at1 pot 30. so —— 1.30. surrey was done at1 pot 30. so —— 1. 30. that would have taken planning beforehand. what we will see now is the police will throw all the resources they have, that are necessary , the resources they have, that are necessary, working with all the forces, so kent, i suspect surrey‘s

been involved in the arrest, all these places will have significant amounts of resources that will be at the disposal of the counter—terrorism officers. i think mark rowley yesterday was reluctant to give details. he kept on saying it's not helpful to discuss things in detail. we see why today. we should be re—assured how quickly the metropolitan police and the counter terrorism command has acted and made the arrest and is continuing to do so with the search. what it shows, as we move to critical, and the fact we've had to rely on the army, it does show the impact of having a 20% reduction in policing. i think that's one of the things we will have to — once this particular crisis is over — we will have to revisit and see what the impact is of reducing the number of police around the country and also reducing the number of armed officers as well. you mention operation temerer there. i wanted to come to that. at

there. i wanted to come to that. at the moment, any way, we're still at critical. cobra has taken the decision to keep us there. presuming there will be a reluctance to drop that level down. it's relatively early. it could run for several days. until they're sure where they are with the two phases of the operation we've seen today, would you expect it to remain at its current level? yeah, i think you're right. the operation is the immediate response. what normally happens and certainly the history of when it's raised from severe to critical, it remains there for a few days and is brought back down. you're looking at enhanced activity. the difference between severe and critical is an attack is likely to an attack is imminent. yesterday we didn't know who was in the cell, whether it's a lone individual, a group of individuals. i think we should have reassurance that significant arrest has been made. a search has been made. normally, if you go by past history of the four

previous occasions, it stays at critical for a previous occasions, it stays at criticalfor a short previous occasions, it stays at critical for a short time, because you need to have additional resources to respond to critical. i think we'll see what we have. one of the concerns i would have around this is that we're bringing in army and the army will be armed, but not used to working with the public directly. whereas the armed officers, i was a gold commander when i was in the police and we had very, very experienced firearms officers who were very, very good at dealing with very complex situations. in fact, dealing with very complex situations. infact, of dealing with very complex situations. in fact, of the couple of hundred firearms operations i was geld on, i never had a police officer fire geld on, i never had a police officerfire a geld on, i never had a police officer fire a weapon, though two of my officers unfortunately were shot in one of the operations. i think the fact that the police officers didn't fire is an investigation of their professionalism. we should be very, very reassured that we have top quality police officers who are working on this, both in the counter

terrorism command and in the metropolitan police and the arrest, the good work done by kent officers as well in making sure that one individual has been detained and pending the investigation. just to go finally back, if i may, to events in sunbury. we don't know any great detail, as you appreciate. we know that there's a significant cordon. we know they're taking a great deal of care about safety. in the same way that cctv, all those details available from the public, they will be looking for all sorts of tiny details here which will tell them presumably whether they‘ re at details here which will tell them presumably whether they're at end of a trail or part way down it. absolutely. it's very unclear. if you look at the previous attacks we've had, we've had lone wolf attacks. we've had attacks with small cells. this is unclear. they will be interrogating telephones, computers, speaking to neighbours. they will look at cctv around that ira. there will be a —— area. there

will be a huge amount of work going on in the background. and in conjunction with m15 and if necessary , conjunction with m15 and if necessary, mi6. that intelligence work will be going round. it will be an intelligence gathering exercise. they'll look at what actions they need to take. # i feel very, they'll look at what actions they need to take. # ifeel very, very reassuring when i hear cresida dick talking this morning about london being a safe place. i felt reassured yesterday when mark rowley was talking about the work they're prepared to do and the fact that he's going to put a huge amount of resources to make sure we catch the culprits. thank you so mouch for talking to me. i said you're on a webcam, but i'm told you're actually in broadcasting house. thank you for that insight. what about the latest from sunbury? it isa what about the latest from sunbury? it is a fast moving situation. dan, you've been following things have we

moved further forward and could you sum upfor moved further forward and could you sum up for people who are just joining us what's going on there? we've seen the initial phase of the investigation at parsons green. then the focus turned to the port of dover. now in this third phase today where counterterror police are now evacuating and raiding essentially a property in sunbury on thames, residential property in what looks to be like a council estate type area, a few miles south of heathrow airport. they have put in a 100—metre cordon. they've evacuated people from the area. they've sent in 60 officers to ensure that whatever they find is made safe and that no—one gets hurt as a result. this operation is ramming up. they —— ramping up. they say it's a precautionary measure following the arrest of the 18—year—old this morning. there will be all the intelligence they've gained from the

device itself, from cctv, from speaking to this person and now, being able to see if this is the property that person was from, what they can find there and what evidence there might be that connects this person to the events of yesterday. thank you very much. i know you're going to keep an eye on things. it is a worrying time, for london, worrying time now for the people on sunbury on thames. cresida dick has been out and about today to offer reassurance. she's been talking to the way the capital should respond to what's been going on and the efforts that her officers are making to ensure that people do feel safe in the current circumstances. yesterday's event was absolutely appalling. horrendous. my thoughts and everybody‘s are with those people who are injured. we had an excellent response. i went to the scene last night. i'm really proud of everybody who coordinated that response. it must have been awful

for everybody on that train. especially those who are badly injured. it's a fast moving investigation. we've got the full weight of the counterterrorist police network. we have our collea g u es police network. we have our colleagues in the intelligence agencies and government helping in every way they possibly can. we're making very considerable progress, you will have seen the announcement ofan you will have seen the announcement of an arrest earlier on in relation to this. we will continue to work as ha rd to this. we will continue to work as hard as we can to make sure that we reduce the threat in this country and that we know exactly who it was who did this, whether there's anybody else involved and try to reduce the risk as fast as we possibly can. the threat level remains at critical. we've seen high visibility today from your officers, lots of sniffer dogs around. this will go on for some time. the threat level is set by thejoint for some time. the threat level is set by the joint terrorism analysis centre. they're independent and they will co nsta ntly centre. they're independent and they will constantly review what is going

on in terms of intelligence and investigation. at the moment, it is at critical. that started last night. that means that we've take an series of measures in london, where i've been today and yesterday, we have more complees on the streets. we have more unarmed police and we have more armed police. the public should feel utterly reassured by that. i've been out and about today. the public seem positive about the number of officers we have here. there's a series of measures to take for the time we are at critical, which means that a threat, sorry, an attack may be imminent.. that is it from scotland yard for now. we are told that we can expect a statement here either in written or spoken form some time in the not too zat future. my colleague dan here is watching events in sunbury. we will come back to you with more when we can. borisjohnson has renewed

the controversial claim that britain will save £350 million a week by leaving the eu, which could be spend on the nhs. the foreign secretary was setting 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. she is due to make a major speech on brexit on friday. kimjong un kim jong un has said kimjong un has said his goal is 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. there are images of an elated kim

jong un present at the launch site. the country's state media has quoted their leader as saying this was to achieve equilibrium of force, so that the united states 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 commenting about the lack of a military option, there is a military option. now it's not what we would prefer option. now it's not what we would p refer to option. now it's not what we would prefer to do. what we have to do acall on all nations, call on eve ryo ne acall on all nations, call on everyone to do everything we can to address this global problem short of war. when the us addmph trinidad and tobago talks 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 re—opening dialogue and resolving the issue through consultation. the resolution should be implemented fully. meanwhile, with no solution in sight, the public in south korea and japan are left wondering what their future might hold. in both countries it's not only the hawks who are considering if they're being adequately protected from a nuclear armed neighbour. (here in seoul, the current crisis is dominating politics. there's an opposition party petition being circulated in an attempt to collect 10 million south korean signatures calling for the re—introduction of tactical nuclear weapons here. the government says it will inflame the situation

and increase the threat to this country's citizens. just an hour's drive away, north korea says it's now very close to achieving full nuclear missile capability. europe's biggest airline, ryanair, has said it's cancelling up to 50 flights a day for the next six weeks, to try to improve punctuality. the move is expected to affect nearly 300,000 passengers, who will be offered alternative flights or refunds. the airline says it needs to have more planes available on standby. some passengers have already been affected. leo belchetz from hackney in london got in touch to tell us about his experience. we're here on holiday in italy. my fiance and i. yeah, basicallyjust received a text out of the blue from ryanair to check our e—mails about our flight cancellation. when we checked the e—mail, gave no indication why

the flight had been cancelled. the information it gave us was that we could rebook through ryanair or apply for a refund. we went to look to rebook through ryanair, there were no seats available until the weekend. our flight was due to depart on tuesday. obviously we need to get back for work on wednesday. so that's unsuitable. the refund is unsuitable because flights with any other airlines cost a lot more than what we would have got back for our refund. we tried contacting ryanair through their web chat, but that's not working on the website. then when you ring them up, you get cut off after saying that the call volumes are too high to take your call. they refer you to the web chat, which isn't working or to rebooking or to rebooking options, which as i said are unsuitable.

in syria, russian troops have taken control of the eastern city of darzor, forcing out the group that calls itself islamic state. it's been held by is for the past three years. russia's presence in syria has helped president assad to keep power despite the country's civil war. the bbc‘s steve rosenberg is the first british journalist to have enter darezor after the militant islamist group 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 reclaim 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.
