we ask those inside the trump administration what the make—up today ‘s speech. —— what to make of today's speech. good evening and welcome to bbc news. 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 put at risk. he said that pyongyang's desire for nuclear weapons threatened the world, and he mocked its leader, kimjong—un, as a "rocket man" 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 editorjon 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 had 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, forfamily, 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. what will stand out from this address will be his comments

on north korea, but there is no simple military solution. well, thank you very much... at a lunch after his outspoken address, the president gave the un a qualified endorsement. and let's give this as a toast to the potential, the great, great potential, of the united nations. thank you all for being here. thank you very much. 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. dozens of people are reported to have died in a major earthquake 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 lunchtime, 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. and already, rescue work is underway. it is not clear how many people may be trapped. this was not even the epicentre. seismologists say that was 70 miles to the south—east, in neighbouring 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, 19 september will be remembered in mexico city for not

one, but two disasters. let's find out what is happening on the ground there. daniel lieberson is in mexico city for us now, and we can talk to him by webcam. just take us through what you experienced when the quake hit. well, it was rather sudden. i was on the 26th floor at the hilton, the second highest building here in mexico city. it was impossible to stand up, everything... we fell down. glass fell, machines fell. it was chaotic. the ironic thing is that, about two hours before, we had a drill for earthquakes. i think people were more prepared than they would have been otherwise. it was very scary. a lot of people coming down, people in wheelchairs, people who couldn't walk, taking them down the escalators, or the stairs. and there were a lot of broken pipes, a lot of slippery areas. the police we re lot of slippery areas. the police were great, a lot of medical

attention. we were taken across the street to a park, and everything went as smoothly as could be done, i imagine. right, 0k, went as smoothly as could be done, i imagine. right, ok, so the irony than that you actually went through an earthquake drill just for this happened. have you had a sense of any of the damaged that has taken place, that has happened in mexico city? have you got a sense of what has happened at? yes, we heard that there is at least five people dead in mexico city, 42 pm. morelos, i know the earthquake was in puebla. but there are have been some people trapped, a couple of buildings have come down. you trapped, a couple of buildings have come down. you were trapped, a couple of buildings have come down. you were high up, in a big building, basically, and the point about mexico city is that it is obviously prone to earthquakes, and all kinds of after—shocks. the buildings, most of them, should be earthquake proof, shouldn't they?” think you are right. it should be earthquake proof, but what seems to

happen, unfortunately, in mexico and other countries, is sometimes the standards are not met for various reasons. at this hotel stood a good shake, andi reasons. at this hotel stood a good shake, and i imagine it will in the future. it supposedly had better technology than most of the other hotels, that is why i stayed here. all right, daniel, stay safe. and thank you very much forjoining us from mexico city after that earthquake, and we understand that around a0 people are thought to have died asa around a0 people are thought to have died as a result of that earthquake. 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 i60mph. maria is now heading towards puerto rico and the british virgin islands, from where our correspondent jeremy cooke reports. 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, 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. .. right until the last minute today, these shattered communities have

been doing their best to prepare. if irma was a knockout punch, what is predicted next feels like a low blow. i'm homeless... for francine, it is all too much. all the shelters are full. and 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 over. the trees, that act like a barricade to the strong winds, all the leaves are gone. some of the trees have fallen. and the trees hold the hillsides. so, if we have a lot of rain, we're going to have some erosion, and potential mudslides. so 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 stomp will pass well south of the british virgin islands. that may mean this sort of rain and flooding, but not further catastrophic damage. jeremy cooke, bbc news, on the british virgin islands. 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, who was a3 and from london, was last heard from a week ago.

brazilian police have made an arrest in connection with the death. in a major speech, myanmar‘s leader, aung san suu kyi, has insisted her government has made every effort to bring peace to rakhine state, where hundreds of thousands of rohingya muslims have fled their homes. in recent weeks, a00,000 rohingya muslims have arrived in neighbouring bangladesh as a result of what the un has called ethnic cleansing. 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 7:00am 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 7:15am train from sunbury station, travelling with the morning commuters from surrey into central london, arriving at wimbledon station at 7:a6am. there, still apparently carrying the highly unstable explosive, it is thought he used the disabled lifts to change onto the london underground system,

apparently spending 20 minutes in the station toilet before, sometime after 8:00am, 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 8:20am, 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. that is a summary of the news. newsday is coming up at midnight. now on bbc news, it is time for newsnight, with emily maitliss. rocket man's on a suicide mission, says trump, as he taunts the north korean leader at the un. yes, the president "united nations", but it was those he saw

as america's enemies. he denounced iran, venezuela, and syria in one go. but it was this threat to kim jong—un that drew a gasp around the world. 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. we'll ask those in his administration and a former australian prime minister what the world is making of an extraordinary speech. boris at bay. the foreign secretary is cornered, and insists he's singing the same song as theresa may on brexit. are you as one? are the two of you as one now? a nest of singing birds. tonight, the first indications of what will be in friday's
