Rescuers in mexico are desperately searching for survivors after a huge earthquake caused widespread damage in the capital mexico city and the surrounding areas. More than 200 people have been killed including more than 20 children who died when their Primary School collapsed. 30 children are still missing, and the death toll is expected to rise. The epicentre of the earthquake was in puebla state, about 75 miles from the capital. It has also caused casualties in the surrounding areas. The earthquake struck on the same day of mexicos worst ever quake in 1985, which killed 10,000 people. A warning there are some distressing images in this report from daniela relph. The desperate search for life. Until lunchtime yesterday, this was a thriving Primary School. Now, it is a mass of concrete and rubble. The mexican president visited the sites to see the rescue teams. Dozens of schoolchildren are still missing. Looking on, family and friends, just waiting. Translation it is sad to see this, because we hope to find people. There are many who have been trapped here and not many who have been taken out alive. Translation i am just rich. I want them to get the children out. By wants to see something. There is sometimes hope when it all seems bleak. Finding a gap in the wall of the collapsed school. Inside, a young boy and girl. Pulled after hours trapped in their own classrooms. Mexico city, one of the most densely populated cities in the world. Now, in places, crushed and flattens, such was the power of the earthquake. Here, the moment it hit. The smoke rising from damaged buildings. Many of those who lived through it recorded what happened, and the aftermath. This is my building. It collapsed. Got to the point and then everything came around. And. Everything is gone ina around. And. Everything is gone in a shopping centre, as its glass roof begins to collapse, this woman got out of the wayjust in time. And here, a dog found by rescue teams, a moment of the mizzen as they their search for those still trapped. The list of what is still needed on the ground is long. Here, asking for antibiotics, bandages, food, as well as water. But despite the ruins, mexico city was not the epicentre of this quake. That was 75 miles away, where the damage and loss of life could be far worse. We can speak now to caitlin grey, who teaches at an academy in mexico city. Thank you for being with us. Tell us where you were and what you we re tell us where you were and what you were doing when the earthquake struck. Hello. I was were doing when the earthquake struck. Hello. Iwas walking in were doing when the earthquake struck. Hello. I was walking in the library at school, and given how close the earthquake was to the city, the Early Warning system did not go off in time. The ground was shaking and students reacted faster than me, i was quite panicked. We evacuated to the library, the front door, very quickly after that. And what was the damage to the school, we re what was the damage to the school, were there any casualties . There we re were there any casualties . There were no casualties in the school, thankfully, but one of the walls of a classroom did crumble and break on the evacuation route, so we were lucky that no one was hurt by that. Mexico has had quite a lot of earthquakes in the past. Some have been out solidly devastating. This one looks to have been very serious with a very high death toll. Did you know straightaway this was another earthquake . Yes. From the reactions of the students at the school, they have already been the through the situation a few times in their lives, their faces and their reactions told me this was a serious and there would be a lot of damage on this one. And in other parts of the city of mexico city, clearly, there have been catastrophic damage and eight height death toll it seems, and one merry school in particular, a number of students have been killed. It is really devastating. We left our apartment and hour ago to come out to one of the areas near us. A line of people we re the areas near us. A line of people were passing by, we are trying to help where we can, they are getting from a to b. There was a Warning System in mexico city. Did you get a for warning that his quake was about to strike . No, not at all. There was not time for it to be triggered because we were so not time for it to be triggered because we were so close to the epicentre. There was an earthquake drill that morning to commemorate the anniversary of the big quake, so it is quite a big coincidence that it is quite a big coincidence that it happened again on the same day. Indeed. Thank you very much, stay safe. A british teacher in mexico city. Joining me now to explain more about the impact of this earthquake is dr laura gregory, an independent Research Fellow at the university of leeds who specialises in earthquake geology. The magnitude has been devastating in its impact even though it is not the highest magnitude. Yes, it is a huge earthquake, so while it is much smaller than the earthquake that happened just over a week ago, it is about 30 times smaller than the one that happened earlier, a 7. 1 is massive. If it was much more shallow, luckily it was a bit deep, but if it was a really shallow earthquake the damage would be even worse. 7. 1 can kill tens of thousands of people if they happen in the wrong ways. We were speaking to our guest to is a teacher there, just talking about the fact that there have been a lot of earthquakes in mexico, they are prone to them, and have ta ken in mexico, they are prone to them, and have taken precautions against earthquakes. Yes, especially after the event in 1985, 32 years ago to the event in 1985, 32 years ago to the day. The rolling codes change dramatically, particularly in mexico city. There is an Early Warning system and that did go off in parts of the city, but it sounds like not where she was, and that is actually not a common occurrence to have an Early Warning system, but because mexico city itself is so susceptible to sean strong shaking, it is particularly relevant for them to have that Early Warning system, and it seems like they are doing drills frequently which can help people in an earthquake, because if you practice how to rob and cover and how to deal with immediate shaking, your instincts kick in and you react immediately and that can really save lives. What about the buildings . Some appear to have completely collapsed. Our earthquake proof are willing in mexico city, do you think . Most of the newer buildings will have been built to quite a high standard. I know there are possibly a few problems with people not quite keeping to that code, but it seems to be pretty good in general. As far asi to be pretty good in general. As far as i can tell, a lot of the buildings that have collapsed our either older buildings or ones that we have what we call soft stories, where there have been some modifications within the story of the building, so they have put a lot of glass wall, creates a real cri n of a real cri n of a real are story, 3 li story £5; 7 32223 sffim§zez§ffifl¥ 52525555232. 7 ~ 7 f eeee efefhezezefiefr 52555533 . 7 ~ 7 f are eeee efeeaezezefefr eeeeieee. ~ 7 ~ 7 f are particularly susceptible the tag; of shaking that they to the kind of shaking that they experience. Just read the, why is mexico so prone to earthquakes question what is the geology of it . It isa question what is the geology of it . It is a susceptible taste. There is a plate that is beneath the american plate, which is to the west of mexico city, in the ocean, the oceanic plate, and where this earthquake happens, that plate is kind of stuck to the north american plate, which is where mexico city sits, and it is back and then it sta rts sits, and it is back and then it starts to bend down deep into the earth, and that bending is where this earthquake happened. It is a strange earthquake for this type of geological setting, so normally we expect there to be a lot of what we call subduction earthquakes on that sort of plate interface, and we think this would happen within a plate where it is kind of bending and starting to go down, but that collision is moving very quickly and that quick rate means that you get more earthquakes. Thank you very much indeed for being with us from the university of leeds, and a specialist in earthquake geology.

Hurricane maria is battering puerto rico, as it continues its destructive path across the caribbean. Its brought with it winds of more than 150 miles per hour. The authorities there say the devastation is expected to be massive. The most powerful storm to strike puerto rico and almost 100 years. The message to the three 3. 5 Million People who live on the island is clear, you must take shelter, you are in danger. We have that experience an event of this magnitude in our modern history. Although it looks like a direct hit, major damage to puerto rico is inevitable, i asked for americas prayers. Hundreds of shelters have been set up by the authorities, and officials feel that fear that the damage left by hurricane erma earlier this month could be extrapolated upon by maria. Take a look at what is happening to puerto rico, just one after the other, but i think we are doing a greatjob. The island of dominica was badly hit earlier in the week. This footage from the air has finally revealed the scale of the damage. Local amateur radio operators say that more than 90 of buildings have been hit. And this was the scene and one loop after maria struck. The clean up will not be quick and it will be costly. Those who manage to get some of the last flights out of the path of the storm to the us mainland consider themselves the lucky one. Init waited on the Royal Caribbean cruise ship that took us to san juan. Caribbean cruise ship that took us to sanjuan. Eye is evacuated. I made it out of puerto rico just before the bad news coming from hurricane maria. The British Overseas Territories are fearing the worst again and the government insists it is ready after criticism it was slow to react to hurricane erma. We have shelter, we have been on it from day one, and we are providing support to people that have lost everything. People across puerto rico are nowjust trying to write out the storm as best they can. But it is moving slowly, and further islands. They also will feel its force soon. Lets hear more about this hurricane. Our weather presenter chris fawkes is here. How did he two hurricanes compare, maria and pam two . Yesterday, we had. React went to a top rated hurricane and at 15 hours, which is an incredible development. It made its second landfall earlier this morning at about 1130 hour time. At this stage, the winds were gusting at about 190 mph. This stage, the winds were gusting atabout190 mph. It this stage, the winds were gusting at about 190 mph. It is working and at about 190 mph. It is working and a northwestern direction and starting to lose some of its intensity. Still a category four hurricane. What is different compared to have two, it stayed offshore, and that is where the stronger the winds were. There was a massive power cuts that the days for it to be restored. This storm is going straight across the island and almost taking the longest track could across puerto rico. This is a very populous part of the island, 3 Million People are in the way of harm, and he storm is tracking over some of the most densely parted areas. The storm is losing some of its peak intensity and it will cause cancer topic damage. Caused catastrophic damage. It is going to get close to the Dominican Republic before spitting up Dominican Republic before spitting up and there is a bit of uncertainty about how strong it will be, but thenit about how strong it will be, but then it looks like it will curve northwards, and will not head into florida, unlike camp three macro, which caused so much devastation. Unlike irma. On the line is Francisco Fernandez who is in sanjuan, the capital of puerto rico. Tell us exactly where you are at taking shelter and what your situation is at the moment. Thank you for having me. Right now we are hunkered down in a closet. There is a little window we can look out of. It is like an attic and you can see it is completely barren. The only thing standing, ironically, the palm trees, but they are built for this. It is like waterfalls from the top floor down to the bottom. We are hoping the funding bill received a little. Hoping the funding bill received a little. The flooding will recede. Communication has been spotty, and we have seen solar panels and shingles flying off of roofs. There isa shingles flying off of roofs. There is a construction site near our house, it is gone, all of it. Right now, we are hoping for the best and waiting to start the process of what will be rebuilding. In terms of the last hurricane, irma puerto rico escape the worst of that, but you have seemed to take in a direct hit with this latest hurricane, maria. It came through the eastside in the south, and last heard it was moving over to the north coast, but it has been terrible, across the island, com pletely been terrible, across the island, completely cut us in half. Irma whats not as bad. The capital got. It was nothing, to this. Stay safe. Francisco, who is sheltering from the hurricane there in puerto rico.

Yes. If ever the United States described iran. There is going to be similar rhetoric. The president of iran has described the speech that donald trump gave as ugly. Speech that donald trump gave as ugly, ignorant, absurd and hateful, specifically saying that the United States, by violating International Agreements, if we think and ability in the world, and crucially, he insisted, all americans should not pull out of the deal that was agreed in the International Community in 2015 to curb the Nuclear Programme for the return of nuclear sanctions. This is what the president said. Translation it would be a great pity if this treaty was to be destroyed by rogue newcomers to the world of politics, the world would have lost a great opportunity, but such were checked behaviour will not impede the course of iran in progress and advancement. There was also a warning and there, the president said that if the americans did withdraw from the agreements, and he said that iran would respond resolutely and decisively. Theresa may was also at the United Nations. What are we expecting from her . She has had a busy day and has been meeting a lot of world leaders.

She is going to be getting back into a familiar theme of saying that Internet Companies, google, facebook and the like, they need to do more to restrict the amount of extremists terrorist supporting content that is on their sites to stop the familiar theme, but one i think she hopes will be given extra focus because of recent terror attacks. We are also told that she is going to be talking about un reform, which has been one of the themes of this week, to say, is there more that this institution can do . I think she is going to add her toppings to that debate. Her opinion to that debate. Thank you.

Nearly a quarter of 14 year old girls in the uk have felt symptoms of depression, according to a study. It looked at data from more than 10,000 young people. Our health correspondent, dominic hughes, reports. Down and lonely and a little bit hopeless. I couldnt see a future. This is how Catherine Perrin describes her 14 year old self, struggling with anxiety and depression, and desperately trying to hold her life together. You have to pretend youre ok every day. The only reason you have to do that is because you dont really know why you are sad and its easier than making an excuse. But you get caught in a web of lies and eventually someone finds you out. Then it makes your situation worse. Now a long term study shows a significant number of teens are also struggling with Mental Health issues. At age 11, parents of boys and girls reported that 12 had experienced emotional problems. But at 1a, when the children ask themselves, nearly a quarter of girls reported feeling depressed. Among boys, one in ten said they had felt down. The numbers of people experiencing depression is increasing. One of the authors of the report says this issue needs to be faced. Problems you express as an adolescent predict later in life. When these people become adults they are more likely to suffer from Mental Health problems. In terms of public health, this is a big issue and we need to look into it. Opening up about how you are feeling can be hard at the best of times. But for these 14 year olds, social media seems to be an added source of pressure. Everyone takes pictures of themselves, posting them on instagram. You have to be dressed nicely for all your pictures. It is an artificial version of you. They are pushing you towards stress. She says she is going to get top grades, so you have to keep that up. These young people born since the turn of the century are the smartphone generation. There is a concern the prevalence of social media on those smartphones is adding to the pressure these teenagers already get from friends, family and school. Dominic hughes, bbc news. Lets go back to that news from mexico of the earthquake and over 200 people have lost their lives in that devastating earthquake. It toppled dozens of buildings in mexico city making people homeless and leaving millions more without power. One Primary School collapsed and at least 20 children at that Primary School have been killed. Joining us via webcam is silvia novoa, National Director of world vision mexico, which has been helping with rescue efforts in mexico city. Talk to us about how devastating this earthquake is going to be from mexico . This is one of the most devastating earthquakes in 1985. We have 39 buildings down in different parts of the city. In the south of the city also. But there are more than 500 buildings that have been evacuated because after the earthquake, some of the buildings will have to be torn down afterwards. We have 600 volunteers who are organising the help of the people is sending. We have warehouses and we are organising it and distributing it throughout the shelters because families are around the buildings waiting for their families to be rescued from the debris. There is a lot of things to do, there is a lot of need around. The information is coming out slowly from the authorities to the organisations that are helping. It isa organisations that are helping. It is a devastating earthquake and in 24 is a devastating earthquake and in 2a hours we have counted more than 200 people are dead and a few more are still trapped in the buildings that have collapsed. We are looking at pictures of buildings that have collapsed and the huge rescue teams trying to find survivors. But the death toll so far of 200 that you mention, do you fear the death toll will rise significantly . You mentioned the other earthquake in 1985, that killed thousands, didnt it . The earthquake in 1985 was 8. 1 on the richter scale. This one was a little bit less than that, 7. 2, or Something Like that. After 1985, the legislation for buildings was changed, but all the New Buildings in mexico city are ok. The problem was the Old Buildings built with the previous legislation, that not only damaged at that time and be more or less recovered them, but now with this new earthquake, most of them are now damaged or collapsed. We feel there is a lot of people still trapped in those buildings, in these 39 buildings that are collapsed. The government, the army are the ones rescuing from the debris and organisations are helping by taking stones out of the area, hand by hand. We are bringing medicine, food and water, and also bringing generators because all around the area, it is completely dark at night. There are many families waiting around, waiting to find theirfamilies. Waiting around, waiting to find their families. Silvia, ithink waiting around, waiting to find their families. Silvia, i think you weigh yourself helping to pull rubble away from collapsed buildings, tell us what that was like, you are doing that right into the early hours of the morning . M is very interesting to see all those buildings down. There are huge amounts of stones. You have to ta ke amounts of stones. You have to take them out to try to rescue people. The president of mexico has ordered that no big machines can enter until at least 72 hours after the earthquake. So it is the time they feel they can rescue people alive, so they dont want to go with big machines. The stones have to be removed hand by hand. So we are doing long lines of people and passing stones hand by hand. Thank you so much for being with us. Sylvia was, as i said, helping to clear rubble from the ruins of collapsed buildings through the night and we are seeing pictures of the school that collapsed in mexico city, where it is feared 20 pupils at least, may have died. A school which completely collapsed, really. It is one of hundreds of buildings to stride by the earthquake of 7. 1 magnitude. It is feared the death toll from that particular Primary School, Young Children there, may well rise. 30 children also missing and a number of adults, presumably teachers, also killed in the school, but at least 20 School Pupils killed in that school in mexico city. One tragedy among many tragedies in the appalling disaster, this latest earthquake to hit mexico, 7. 1. Some of the other stories making bbc news at 5. 00.

The two companies have been in negotiations since last year, when tata halted the sale of its uk business. The new business is expected to employee 118,000 people, but there will be 4,000 job losses across europe. The business secretary greg clarke, is cautiously optimistic over the deal. It isa it is a step in the right direction, a very positive step. When you consider that just a very positive step. When you consider thatjust over a year ago, it was being thought that the port talbot works in particular, might have too close. Then this announcement secures the future of port talbot and the other tata steel making sites right across the uk. It is a good step forward.

They are of said its bombing strikes have been launched. This report from Jonathan Beale contains pictures you may find disturbing. This is where they have been running the Bombing Campaign against a group known as Islamic State for the last three years. The sprawling Us Military Base in the qatari desert. Hidden away in a reinforced concrete bunker is the nerve centre. From here, they watch live feeds from dozens here, they watch live feeds from d oze ns of here, they watch live feeds from dozens of Coalition Warplanes flying over iraq and syria round the clock.

The defence secretary says the mission is far from over. He travelled to the region to thank the troops and to tell them they were making a difference back home. What we have been faced with over the last three yea rs been faced with over the last three years is specific attack planning from cities like mosul against targets in western europe and against targets in britain. It was essential we take action to deal with that. The uks contribution might be helping in the fight against is in iraq and syria, but the attacks on britain have shown the attacks on britain have shown the ideology has spread and it will be defeating with just bombs and bullets. Theresa may will use a speech at the United Nations in new york to urge Internet Companies to take stronger action against online extremism. She is expected to challenge them to take down terrorist material within one to two hours of it first appearing. Joining me now from Dartmouth College in New Hampshire is dr hany farid Senior Advisor to the counter extremism project an International Policy organisation formed to combat the growing threat from extremist ideologies. How important do you think the internet is and do you think the Prime Minister is onto something . think she is right and it is long overdue. We have seen abuses from early 2000 ranging from child pornography, drug dealing, arms trade and extremism. For the most part, the internet and social Media Companies have said, we dont know what to do so we will do anything. But i think the time is overdue, we had to realise there are real implications to the bad behaviour online and we have a real aggressive stance. What contents are you worried about . A lot of things, child pornography, child sex trade, incredible numbers of Young Children who are being exploited and traumatised for years to come. The domestic and International Terrorist site, radicalisation, recruitment and the equipping of terrorists who are then going out and committing the types of crimes we are seeing around the world. These are not a bstra ct around the world. These are not abstract ideas, its not people saying things we dont like or disagree with, it is people conspiring and training people to go out and commit horrific crimes with very real world consequences. It is not an abstract idea any more, we have to get a handle on this. Not an abstract idea any more, we have to get a handle on thism looks like the big Internet Companies are beginning to respond, but have they been a bit slow, a bit tardy . No question they have been slow and no question they are starting to respond, but there is no question the response is not volu nta ry. Question the response is not voluntary. They are responding because of pressure from theresa may, the eu and capitol hill in the states. Where in not for the threat of legislation or civil and criminal penalties, i dont think you would see any movement on that front. We have to understand these companies will act in their own interests and their own financial interests. Thats fine, but then we as political bodies and as the public, have two call on them to rein in the abuses because they will not do it on their own. You are right they have started moving, it is too slow and not aggressive and not. They are doing the bare minimum they need to doing the bare minimum they need to do in order to emanate the tabla criticism that is being discussed. Thank you for your time. Our security correspondent Gordon Corera joins me. Bea be a bit more specific as to what theresa may is asking them to do . They are talking about getting this extremist content of the platforms within two hours because it is within two hours because it is within that period the links are shared which means it spreads further or to stop it getting uploaded in the first place. That is what the British Government really wa nts, what the British Government really wants, is for the Tech Companies to develop systems which spot the actors who are trying to put up this material and block them from putting up material and block them from putting up the material, or quarantining the material to check it, so it doesnt emerge in the first place, rather than just taking it down once it is already up there at whatever pace they manage. The companies have started to use Artificial Intelligence and Machine Learning to spot this material and share information between them. You have to differentiate between someone posting a video which has a bit of isis propaganda, but is actually a news video about isis propaganda or which features of the material and differentiate between the two things. There are technical challenges for the Tech Companies are doing this, but the governments view is, you are the companies, good at finding solutions, do it. They are also rich, well resourced so no shortage of funds to develop these things . The Tech Companies make money of this material. It isnt just a neutral platform that allows this to be spread, they selling advertising acrostic, using the data from the who upload it to internalise that money and then is advertise it. If they are making money from it, they have a responsibility to police it and rather than passively wait for the British Police to report to the companies there is something which breaches their guidelines. The government wants the companies themselves, if you like, to do that policing. Gordon, thank you very much.
