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. Were really scared.

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. And, you know, 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 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.

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 bbc were the first on the ground on the island of barbuda as a Mass Evacuation was taking place. Heres laura bicker with a specially extended report were not coping. Were definitely not coping. Where can we live reand what can we do . My whole life is here, so. Describe the night here. What happened . Well, it started off with the wind. It wasnt, like, life threatening. It started picking up and then it came in, the wind picked up harder and harder. At the time, i was sleeping and my brothers woke me up, the windows blew open, and hes trying to pull in the roof and i was holding him, we were fighting the wind. The roof came off. Then my bedroom came off. We went in the living room. We had all of this boarded up. The British Virgin islands look like they have been hit by the blast wave of a bomb. 0n the biggest island, houses have been ripped apart. Contents scattered for miles. We had to leave. The wind picked us up. In the moment it was like your life was on the line. She had her arm around a post after the roof came off. The walls were caving in. She had her other arm around a child. She said the wind just pulled a child out of her hands and that was the last they saw of the child. The night was restless. You couldnt get to sleep. You were up all night. Everything just started to decay and just crumble. What have you eaten in the last few days . Nothing. Hardling anything, cause you cant cook, so you have to have a biscuit, tea or water, or whatever. What do you do now . I have no idea. Everyone now with homeless. No one has anywhere to go. Everyone is in the same situation and no one can help each other because Everybody Needs help. The objective this morning is to make sure we get every single resident off barbuda. We now have a mandatory evacuation in place. Im going there to urge the residence, those who are defiant, to vacate the island. We cannot afford a situation in which barbuda is hit by yet another hurricane, jose, in these conditions. Dont worry. We will get you off the island to safety. You will be taken care of. Can it land . Dont worry, youll be ok. The sheer horrifying scale of the devastation means barely a building can be salvaged. That means the whole island will have to be rebuilt and the government has admitted it simply does not have the money. Were hoping governments and International Partners will step up to assist us. Have you got enough food, water . No. Everybody is fighting and stealing. A lots going on now. People are breaking into peoples homes and taking what they have. Its a state of emergencies. Yelling when it came to the opening of this supermarket just an hour ago, we witnessed shocking scenes. People were waiting for up to eight hours in 35 degree weather. They are looking for basic supplies such as water, any canned goods. When it comes to the local ministers, they told me it is simply not true that people are hungry. But i have been here on this island for the last five days and that is not what they are telling me. I have seen real stress, real determination, but now what i am seeing is real desperation. We need water and food. We need electricity. Have you had enough help . I dont think so. You can go down there for a bit. We are fine. We are under control. But theresjust we did not expect this mess today. We onlyjust got out of our house today. As we were filming, a local government minister approached. We have lots of food arriving tonight. For this market and other markets and lots of food arriving every day this week. We are trying to make some phone calls. How have things been for you . Really difficult. There is no food or water. Weve heard some people are bringing help. But we havent seen anything. They are organising the logistics and while that happens, people are suffering. The food, a week ago it was already finished. We have more children. It is tough. We have been told not to walk too far up this street because the number of serious criminals are still on the loose from the damaged prison. Something else for the government to deal with. When you walk around this neighbourhood you get a real sense its not just about rebuilding lives and homes, its about rebuilding trust. Hi. Is this where you live . I live right around the corner. You dont want to see my house. Whats happened to it . Its completely decimated. I am feeling hungry. Is it acceptable that seven days after the hurricane there is limited access to food and water . Youve got huge amounts of both coming in today. Today is seven days after the hurricane. People have not had water for seven days. I can tell you that the uk has made a huge effort. I have just talked to the premier, who says they have enough for two months here. We are intensifying the effort. I think most people would say the uk has made an absolutely stunning effort to get support to this island, to help bring law and order, after what has been an unprecedented natural catastrophe. This was the bar here. First i have to get it cleared up. First, clean it up. A lot of work. Do you think you have got the money to do it . No, but ive got the. White sands is one of the most exclusive beaches on the British Virgin islands. Every decimated building you see was a bar, a restaurant, someones main income. Theyll need to be rebuilt if this islands to survive. How many people have you been feeding . 50150. It has basically been a Community Effort to build this shelter. The experts will give us the ability to rebuild in a way that we want, because in many ways we did what we could in terms of building. The fact that theyve built something this substantial is due to them. But if we as a Community Come together we can have a community shelter, which we by the way dont have as of now. Have you got the determination to do this . Do we have the determination . you ask a very simple question no, we have the determination. This is not only determination, it is a challenge. We have so much potential. I mean, look at these kids. These kids they have gone through a traumatic experience but theyre not as traumatised as you would expect. I think when everyone who needs to leave or would like to leave gets off the island, which will happen pretty soon,
