britain takes advantage of all opportunities brexit provides. mexico has been hit by a powerful earthquake. dozens of people have died. many buildings have collapsed. more devastation in the caribbean. we report on the path of hurricane maria, which has already hit the islands of guadeloupe and martinique. after the terror attack in london, a third man has been arrested in newport, south wales. and in tonight's football, england's women coast past russia in their opening world cup qualifier. coming up in sportsday on bbc news, i'll have details of a century forjonny bairstow as england ease to victory over the west indies in the first one day international at old trafford. good evening. president trump, in his first address to the general assembly of the united nations, has threatened north korea with destruction, if america or its allies are threatened. he said that pyongyang's desire for nuclear weapons threatened the world, and he mocked its leader, kim jong—un, as a "rocketman" on a suicide mission. president trump also took aim at the iranian leadership, describing it as a corrupt dictatorship that exported violence. our north america editor, jon sopel, reports from new york. donald trump is used to being the centre of attention, but rarely has the global community waited with such bated breath to hearfrom him at his first address to the un general assembly, the isolationist "america first" president at the very embodiment of multilateralism and multinationalism. he was more conciliatory, but he was still donald trump. as president of the united states, i will always put america first, just like you, as the leaders of your countries, will always, and should always, put your countries first. he'd come to hug his friends and wallop us enemies, and none more so than north korea and their leader kim jong—un, or rocket man, as he called him. in the assembly, north korea's two allocated seats stood conspicuously empty. the united states has great strength and patience, but if it is forced to defend itself or its allies, we will have no choice but to totally destroy north korea. rocket man is on a suicide mission for himself and for his regime. the united states is ready, willing and able, but hopefully, this will not be necessary. on the iran nuclear deal, he hinted that america could still walk away from it. "you haven't heard the last of this," he warned. but he ended up with a rallying cry for strong sovereign nations working together. we will fight together, sacrifice together, and stand together for peace, forfreedom, forjustice, for family, for humanity, and for the almighty god who made us all. thank you, god bless you, god bless the nations of the world, and god bless the united states of america. thank you very much. what will stand out from this address will be his comments on north korea, but there is no simple military solution. at a lunch after his outspoken address, the president gave the un a qualified endorsement. let's give this as a toast to the potential, the great, great potential of the united nations. thank you all for being here. whatever its perceived shortcomings, the best way to make progress with pyongyang and on other issues will still be via this body, and the president seems to know it. let's go live to new york and jon is there for us. we heard the strong words and you underlined it in your report, but the question is: has anything changed really, in terms of the president's policy and his options? yeah, i mean, you're right, the words were very strong indeed. when have we ever heard a president of the united states threatening to destroy another country, as donald trump did in his speech? when have we ever heard a president summoning his inner elton john we ever heard a president summoning his inner eltonjohn and calling another leader rocket man? i think it was the odd conjunction of those two things, one, the most serious threat you can make against another nation and the other, almost a flippant, nation and the other, almost a flippa nt, playground comment flippant, playground comment calling him rocket man. what will reassure people is that donald trump seems to think that the path to getting progress is through the united nations and if he wants to influence china, which is still the key to the crisis in north korea, then that is best done as well through the un. it's interesting, i spoke to a couple of very senior un officials at lunch time, as they were leaving. they felt quietly reassured by what they'd heard from donald trump, that it was nothing like as bad as they feared it could have been. but maybe that just tells us feared it could have been. but maybe thatjust tells us more about expectations. jon, again, thanks very much. let's talk about the situation in mexico tonight. dozens of people are reported to have died in two major earthquakes in mexico. buildings have collapsed, fires have broken out, and the mayor of mexico city says people are trapped inside some collapsed structures. our correspondentjames cook has the latest. mexico city is one of the most densely packed places on earth. more than 20 million people live in this metropolis. any powerful earthquake here is especially devastating. the huge tremor struck around lunch time, prompting panic. these mobile phone pictures show what appear to be columns of dust from collapsed buildings. fires have been reported. and people are being urged not to smoke because of the danger from gas lea ks. smoke because of the danger from gas leaks. already, smoke because of the danger from gas lea ks. already, rescue smoke because of the danger from gas leaks. already, rescue work is under way. it's not clear how many people may be trapped. this was not even the epicentre. that was 70 miles to the epicentre. that was 70 miles to the south—east in puebla province. these distressing pictures appear to show buildings collapsing in the aftermath of the quake. many people had fled into the streets, but not everyone. this damage happened on the anniversary of the devastating 1985 earthquake. this morning, many residents had taken part in an emergency drill preparing for exactly this event. now the 19th september will be remembered in mexico city for not one, but two disasters. james cook with the latest on the earthquake in mexico. the foreign secretary, borisjohnson, has dismissed claims that he's considering resigning because of differences within government about the brexit process. mrjohnson — who's attending the un general assembly in new york with the prime minister — described the cabinet as a "nest of singing birds". later this week, theresa may will set out the government's latest thinking on brexit in a speech in florence, where some expect her to tackle the issue of whether the uk would pay for continued access to the eu single market for a transitional period. 0ur deputy political editor, jon pienaar, reports from new york. there is flash photography in this report. you're not going to walk, you're just going to run? no, no, no. guess who we saw back from jogging. boris johnson didn't look much like britain's foreign secretary, gossip or no gossip, he wasn't planning to quit thejob in a or no gossip, he wasn't planning to quit the job in a row over brexit or so he said. we're going to deliver a fantastic brexit. we're working together. the key thing is to make sure that britain can take sarong of the opportunities that brexit provides. are you as one, are the two of you as one? nest of singing birds. theresa may would love to be sure of that. she's got enough on her plate, here at the un, meeting the secretary—general and a diary full of leaders, while planning her next move on brexit. and trying to sound confident, that won't be derailed by ministers splitting or quitting. the government is absolutely clear and the cabinet is clear and boris and the cabinet are clear and boris and the cabinet are clear that we have one focus in what we're doing on the european... you believe he's not about to walk? we are very clear that we have one focus and we're all working together to achieve that aim, which is the best possible deal for the united kingdom in leaving the european union. the prime minister's diary is always a nightmare. there was the south korean leader to meet, president erdogan too and leading business people. brexit, the issue hanging in the air, more so ahead of her big speech in florence on friday, potentially a make or break moment for cabinet unity and eu negotiations, especially if she promises tens of billions to brussels after brexit. no more clues on that today though. she was just getting on with it or trying to. you knew thisjob getting on with it or trying to. you knew this job was going to be tough. you can't have known quite how tough. any regrets? i'm doing what i a lwa ys tough. any regrets? i'm doing what i always do, what i've done throughout my life which is getting on with the job in hand. i think that's what the british people want their prime minister to do. theresa may still ticking off her list of people to see and later, she could bejoined by borisjohnson, see and later, she could bejoined by boris johnson, at see and later, she could bejoined by borisjohnson, at a commonwealth reception. he's due to join by borisjohnson, at a commonwealth reception. he's due tojoin her again for her speech in italy, which will be unveiled to cabinet ministers a day in advance. a lot depends on his verdict. parts of the caribbean — already devastated by hurricane irma — are in the path of a second powerful storm. at least one person has died as hurricane maria hit the island of guadeloupe, and there are reports of extensive damage to dominica, where there were torrential rain and winds of more than 160 mph. hurricane maria is heading towards puerto rico as well as the british virgin islands, where we can join our correspondent, jeremy cooke. she is a mighty force of nature, barrelling in from the atlantic. hurricane maria hit guadeloupe hard, the french authorities talking of extremely violent winds, ordering people to stay indoors. in martinique too, high winds and heavy rain as the hurricane eye passed within 30 miles. widespread flooding. but perhaps the worst so far has been dominica, conditions so bad that hardly any pictures have emerged.. an unverified video posted while the lights went off. the church roof, blown in. my neighbour's roof, gone. even the prime minister could not escape the storm, posting on facebook: here in the british virgin islands, if irma was the knockout punch, what's predicted next feels like a low blow. for francine it's all too much. all the shelters are full. this is the devastation, you notice i have on different shoes. i can't find any clothes. you notice how i'm dressed. we really need help here, because a lot of people are suffering. the harsh reality here is that all the tons of debris can't be fixed down or made safe before the next hurricane is due to hit. adding to the problems here, the drains are clogged with debris, more flooding seems inevitable. there's a lot of loose debris all overment the trees act like a barricade to the strong winds, all the leaves are gone. some of the trees have fallen. the trees on the hillsides, so if we have a lot of rain, we will have some erosion and potential mudslides. that's a big concern. everyone here is doing all they can to prepare. more than 20,000 british citizens facing their second potentially devastating hurricane in as many weeks. indications that hurricane maria is making landfall here on the british virgin islands. what we don't know, of course, is the strength of the winds, which we will face here in the coming hours. the hope is that the eye of the storm will pass well south of the british virgin islands, that may mean this sort of rain and flooding, but not further catastrophic damage. that was the situation in the british virgin islands. let's go to puerto rico. to be honest with you, it isa puerto rico. to be honest with you, it is a strange combination of expectation and nervousness here in san juan. there's a expectation and nervousness here in sanjuan. there's a lot of last minute preparations going on, with people boarding up their homes and businesses. people have been buying water, bottles of water, buying fuel for their generators and so on. schools are closed. businesses are closed. the streets are now empty. that nervousness i mention is because hurricane maria comes quick on the heels of hurricane irma. people here are thankful they avoided the worst of irma a week ago, but are unlikely, they fear, to avoid it twice. there's over one,500 rivers in puerto rico. it's worrying times as maria gets closer and the hours tick away for what will be the biggest storm to hit here in almost 100 years. is a brief look at some of the day's other other news stories. the number of people who died in the grenfell tower fire injune may be slightly lower than originally thought, according to police. initial estimates suggested around 80 people had been killed. detectives say the investigation may also consider individual charges as well as corporate manslaughter. a british woman who disappeared in brazil during a solo kayak expedition along the amazon has died. emma kelty, from london, was last heard from a week ago. the scottish and welsh governments have published amendments to key brexit legislation at westminster. they say it's aimed at preventing the uk government from taking control of devolved policy areas when powers are returned from the european union. scotland yard said tonight that a 25—year—old man has been arrested in newport, in south wales, in connection with the parsons green terror attack. and the bbc has learned that an 18—year—old arrested on suspicion of carrying out the attack had been previously referred to a government counter—extremism programme. detectives have been granted more time to question him and another man. the suspected bomber left the train at the stop before parsons green, where the bomb material caught fire. our home affairs correspondent daniel sandford has the story. still a major crime scene, the mauve terraced house in sunbury—on—thames where an 18—year—old man had lived with his foster parents. a young man who the bbc has confirmed had been referred to a counter—extremism programme, a young man neighbours rarely saw. i've never seen him enter or exit. even when the police were there, i never saw him. last friday, a man was seen in the street at the rear of the house at around seven in the morning and was recorded on multiple cctv cameras heading towards the nearest railway station. in his right hand, what seems to be the bomb which, if it had been correctly made, could have killed many passengers. he seems to have taken the 7.15 train from sunbury station, travelling with the morning commuters from surrey into central london, arriving at wimbledon station at 7116. there, still apparently carrying the highly unstable explosive, it's thought he used the disabled lifts to change onto the london underground system, apparently spending 20 minutes in the station toilet before sometime after eight o'clock boarding a district line train. detectives now believe that the suspected bomber left the district line train here at putney bridge station, the last stop before parsons green and just 90 seconds' travel time away. but police are less sure what he did next, and they could do with the public‘s help. at 8.20 at parsons green station, the bomb in a bucket produced a sheet of flame, but didn't detonate. the attempt to add to the death toll in this year of terror had failed. daniel sandford, bbc news. the uk has suspended its cooperation with the army in myanmar because of the humanitarian crisis affecting rohingya muslims. but the country's leader, aung san suu kyi, said today that her government did not fear international scrutiny of its handling of the crisis. it was her first public address since violence in rakhine province has sent 400,000 rohingya muslims fleeing into neighbouring bangladesh in what the un has called ethnic cleansing. in a moment, we'll have a report from jonathan head, who's been talking to rohingya refugees in bangladesh, but first, jonah fisher was in naypidaw, the capital of myanmar, to listen to aung san suu kyi's speech. myanmar‘s nobel laureate arrived for her speech, a once unthinkable question hanging in the air. ms suu kyi, have you become an apologist for ethnic cleansing? there was no reply. that's aung san suu kyi's style these days. in the last three weeks, 400,000 rohingya muslims have fled her country, and she's said very little. ms suu kyi, do human rights still matter to you? this televised address to diplomats was ms suu kyi's chance to state her case to the world. we feel deeply for the suffering of all the people who are caught up in the conflict. those who have had to flee their homes are many, notjust muslims and rakhines, but also small minority groups. this was ms suu kyi giving the "both sides" defence. 0verwhelmingly, the victims in this crisis have been the rohingya. as to who was responsible for burning villages, she refused to point the finger. and then, to many people's surprise, there was this. we are concerned to hear that numbers of muslims are fleeing across the border to bangladesh. we want to find out why this exodus is happening. we would like to talk to those who have fled, as well as to those who have stayed. this speech will not satisfy ms suu kyi's many critics. a generous reading of it is that she is badly out of touch. but the idea that she put forward, that she doesn't know why hundreds of thousands of rohingya have fled into bangladesh, well, that simply beggars belief. ultimately, ms suu kyi doesn't control the burmese army, but its generals seem quietly pleased that it's her taking the flak. what will it take to stop the abuses? why have so many people fled and why aren't your soldiers stopping the burning of villages? interpreter translates question. translation: this is their strategic plot. the rohingya were the ones who started attacking security forces. then they ran away. they knew what they did, then got worried about it and ran away. aung san suu kyi has made her choice. her relationship with the military and the stability of the government comes before the rohingya and what's left of her international reputation. this is what aung san suu kyi did not talk about in her speech today. it's a rohingya village being burned down by rakhine buddhists, in the presence of the police. i filmed this 12 days ago, two days after the date that ms suu kyi says all military clearance operations had stopped. as i watched those burning buildings over in rakhine state in that village, i wondered what had become of the inhabitants, looking at the clothing strewn on the path. now i'm over on the bangladesh side of the border and we've met up with a man called abdul majeed. he's brought his family here from that village to build a home in a new bamboo and plastic sheeting community that's sprung up just behind these rice fields. abdul majeed took me up to his new home, where a village is being hacked out of the muddy hillside. so many rohingyas have arrived over the past two weeks that there is no room in the existing camps. these people are paying a local farmer for their tiny plots of land. abdul majeed shares this patch of ground with his wife and five children, their only shelter flapping sheets of plastic that blow off during the monsoon storms. i showed him what i had filmed of his village being torched. he recognised the madrasah, and a tea shop in the marketplace. he had been reluctant to leave, he said, but they had been shot at by the burmese army for more than an hour. translation: even if they gave us a sackful of money, we wouldn't choose to stay here. if they didn't shoot us in myanmar and there was peace, we would go back right away. we are not happy here. we are not here for the food, but only to save our lives. aside from some clothing, this is all abdul majid's family has left, burmese currency worth about 70p. the plight of other recently arrived rohinyas is scarcely any better. they are making do in conditions that defy description, bare existence in the mud and trees and nothing else. jonathan head, bbc news, cox's bazar, bangladesh. the home office is investigating allegations that the security firm gas provided inaccurate information about two immigration removal centres. it follows an undercover bbc panorama investigation which exposed abuse and self—harm at the brick house under. documents seen by the bbc also suggest the company was making significant profits from running the centres. gas says it has never deliberately given false information to the home office. a stretch of the m1 motorway was closed today as police investigated a suspicious object. detectives say the object, which was found under a bridge, did not turn out to be explosive, but did appear to be chemical in nature. thousands of drivers were stuck there for hours. in his first speech to the liberal democrat conference as leader, sir vince cable has said he is proud to describe himself as a brexit saboteur. he said britain would be poorer and weaker after withdrawing from the eu, and he wanted the party to lead the fight against leaving. he also called for wealth taxes and suggested a crackdown on property speculators to ease housing problems. our political correspondent eleanor garnier reports from bournemouth. after two dismal election results, the liberal democrats need a revamp. vince cable's not exactly a fresh face on the political scene, but the 7a—year—old says this is the time for grown—ups in all parties to join forces and prevent brexit becoming a disaster. his promise, a referendum once negotiations with the eu have finished. this is not a call for a rerun. it is not a call for a second referendum on brexit. this is a call for a first referendum on the facts. the lib dems should lead the fight against brexit, he said. but we should not be consumed by brexit to the exclusion of everything else. we're not a single—issue party, we're not ukip in reverse. he said returning to government was his aim. and my role as your leader is to be a credible potential prime minister. applause. sir vince called for major public spending on infrastructure, a penny rise in income tax to fund the health service, and government backed house—building to help young people onto the property ladder. we've got to end the stranglehold of oligarchs and speculators in our housing market. i want to see fierce tax penalties on the acquisition of property for investment purposes by overseas residents. at the last election, opposing brexit didn't attract voters in the way the liberal democrats had hoped. in this speech today, vince cable's trying to show that he's prepared to grapple with the broader issues facing the country, and he hopes that his past experience in government will add credibility to that message. vince cable is sounding ambitious — what do lib dem members make of it? vince cable says he could be the next prime minister — it's not going to happen, is it? not with that attitude, i don't think so. i think absolutely going forward, he could be, and i think we all truly believe in liberal values and that's exactly why we're here. macron became president, so, you know, anything can happen. are things volatile enough to get vince cable into number ten? why not? why not indeed ? now, this veteran politician must show that he can deliver results. vicki young, bbc news, bournemouth. football, and england's women dominated their opening world cup qualifier against russia tonight. mark sampson's side scored six goals to sweep away the group's second seeds to take their first step towards the tournament in france 2019. katie gornall was watching the action. england's first steps on the road to the world cup, and their manager is under the spotlight. mark sampson has been accused of discrimination by two former players and although cleared of any wrongdoing, it's all taken a toll. on the pitch, england presented a united front. russia we re presented a united front. russia were expected to be their toughest opponent in this group, and yet samsung's side dominated from the start. it was manchester city's nikita paris who settle the early nerves. a goal scored and a statement made. a very significant moment. with fran kirby pulling the strings at number ten, the lionesses we re strings at number ten, the lionesses were purring. this was now a lesson in the art of finishing, as lucy brahms put them a—0 up before half—time. the english tide kept coming and russia had no way of turning it back. 6—0 the final score, a result and a performance that will be welcomed by one man in particular. it was a difficult time, but it's a difficult time for eve ryo ne but it's a difficult time for everyone involved. this is a serious situation and everyone is aware of that. we tried our best to be as respectful as we can, but it's about the football and the players have focused on that. northern ireland's world cup qualifier failed to deliver the same positivity after they were beaten by the republic of ireland was not a dipping shot from megan campbell completing a deserved 2-0 megan campbell completing a deserved 2—0 win for the visitors. so it difficult night for northern ireland, who already face a battle to qualify for their group. in contrast to that resounding win for england earlier. on the pitch, it's all gone like clockwork, but off it, there will be tougher challenges ahead for mark sampson, with senior executives from the fa set to face a parliamentary inquiry next month, looking at potential holes in the two investigations that cleared sampson of alleged bullying and harassment of chelsea striker any aluko. katie gornall, thank you. newsnight is coming up on bbc two. as trump threatens north korea with total destruction, we ask those inside the trump administration what to make a debate's speech. join me on bbc two. and there will be more coverage of the earthquake in mexico throughout the earthquake in mexico throughout the night on the bbc news channel. here on bbc one, it's time for the news where you are. good evening, i'm alpa patel. a former head teacher from london who had been kayaking
