these are some of the main stories, in mexico, magnitude 7.1 earthquake, these are some of the early pictures, we welcome back to the story in a couple of moments. donald trump is saying he is prepared to destroy north korea... rocket man is ona destroy north korea... rocket man is on a suicide mission for himself. and for his regime. all saints eg has broken her silence on the revenge of muslims crisis, but she has not satisfied her critics, she did not speak to the bbc either, but her speech has apparently been popular inside myanmar. —— aung san suu kyi. the bbc science editor will explain some potentially better news in the fight to slow climate change. turning back to the powerful earthquake in mexico, 7.1, there are reports that

up mexico, 7.1, there are reports that up to 20 buildings may have partially collapsed, and some people could be caught in the rubble, also reports that there are fires. this is some of the wire copy coming through the newsroom. this is run writers, quoting local officials, at least four dead. 0ther writers, quoting local officials, at least four dead. other local officials put the figure at five. as i was saying a few minutes ago, we have reported thousands out on the streets of mexico city because they have been forced to step outside for fear of the safety of their building. 0urfocus has been mexico city, but actually, the epicentre is a town about 50 kilometres to the south, about 25 minutes ago we played a video recorded by the bbc mundo reporter, who is in mexico city, hejoins us mundo reporter, who is in mexico city, he joins us live. mundo reporter, who is in mexico city, hejoins us live. juan, how

are you, i know that something fell on your head from one of the buildings. ed beard of the roof, from the bbc bureau, he in mexico city. —— a bit of the roof. i was running quite quickly downstairs, and into the streets. —— here in mexico city. i was not sure i was going to make it, luckily, i am still here. and many people, thousands of people, went into the streets after this quite heavy and prolonged shaking. 0n streets after this quite heavy and prolonged shaking. on an especially poignant day, this is the 32nd anniversary of one of the greatest days —— worst days in mexican history, when an earthquake left 10,000 people dead. i have been without phone signal for the last couple of hours. i have heard reports of victims. i understand

dust has spread across the city, and rescu e rs dust has spread across the city, and rescuers are underway, to find people trapped. and this process is taking place, less than two weeks, another earthquake left almost 100 people dead in southern mexico. i was there, covering the aftermath for a few days and experienced some after—shocks but nothing like the ones we have seen after—shocks but nothing like the ones we have seen here today, and as isaid, ones we have seen here today, and as i said, sent thousands of people into the street ‘s, obviously, in shock, nervous, crying, trying to reach their relatives over the phones, but the lines were down. ——

streets. it has been a very special moment for the last couple of hours, as you can understand. sounds terrifying. described the moment the earthquake struck, for us. why was in my office... i was in my office, i was preparing to do an interview ona i was preparing to do an interview on a different subject, not the anniversary of the earthquake or anything like that. and it started shaking the whole building. i have to say. 0ur shaking the whole building. i have to say. our office is in a part of the city were normally, the earthquakes are felt more strongly. sol earthquakes are felt more strongly. soiam earthquakes are felt more strongly. so i am quite used to it but it was nothing compared to what i had felt before. this was something special, i had to evacuate. i managed to grab

my phone, grab my computer, and ran downstairs. a piece of the roof struck me on the head. it was quite tense. as i was going downstairs, i started to see how the building, the walls, started to crack. it was quite stressful. i can imagine it was. thank you for speaking with us, i hope you and your colleagues and eve ryo ne i hope you and your colleagues and everyone else in the building is ok. thank you for bringing us up to date. also, as he was saying, and as i was saying, unfortunately, the death toll is starting to rise, we are seeing now, the governor of the central mexican state of morale loss is saying that 42 people have died,

we only had five confirmed deaths, 110w we only had five confirmed deaths, now the figure has been putjust in one state in mexico at a2. —— morelos. unfortunately that figure is likely to rise further. as and when we get information we will bring it to you. for a moment we will turn back to donald trump, delivering his maiden speech to the un general assembly, nothing was off—limits, very critical of north korea, iran and venezuela, in case you did not see what he said, it was extraordinary, i will let laura described it, she is live from new york. i'm not we have ever heard language like it, she called him the rocket man... i mean, he called him the rocket man. he said that he was on a suicide mission, he called kimjong—un " rocket mission, he called kimjong—un "rocket man", mission, he called kimjong—un " rocket man", he mission, he called kimjong—un "rocket man", he said that he would totally destroy north korea if it did not stop on this part of nuclear tests. it was quite something to

come to the united nations, the heart of diplomacy, trying to avoid conflict, and essentially, as one do dramatic source said jimmy, threatening conflict against another member state, although north korea has been incredibly provocative and donald trump said he hoped that it would not be necessary, he thanked russia and china for their role in placing tough sanctions on north korea. —— as one diplomatic source saidjimmy. the korea. —— as one diplomatic source said jimmy. the array nuclear deal, it has stopped work on its programme in return for having punishing sanctions lifted against it, donald trump said that deal was in paris meant and he hinted he will not recertify it when he gets the opportunity in the middle of 0ctober, which could lead to the unravelling. quite the day here at the united nations. the weather, matching the slightly stormy atmosphere inside. i guess one of the things this teaches us is even though there has been a lot of churn

inside the white house, steve bannon in particular leaving, donald trump very much the same man who campaigned to give president last year —— campaign to be the president last year. he said, i put america first, you should put your country's first, you should put your country's first as well, this had echoes of his inaugural speech, when he talked about the forgotten people left behind by globalisation, he made a passing reference to that today. what people inside the building are committed to globalisation, multilateralism and all of those other things, what those people are concerned about is the emphasis on sovereignty. chinese and the russians are always talking about sovereignty inside the united nations and it means, we do what we wa nt nations and it means, we do what we want and you cannot tell us what to do and there is no global order relating to human rights and all the rest of it. it is how the speech will be read outside. no mention of russian aggression, a passing reference to ukraine. and yet the

nato secretary—general told me that russia is one of the biggest threats. facing the order. vintage donald trump here at the united nations. we will speak with you tomorrow. if you want more information on the stories we cover on outside source, go to the bbc news website. you will get the latest on the mexico earthquake, the dramatic fallout from donald trump's un speech and if you want to see it, clips of aung san suu kyi's speech on the red tinge of muslims. —— 0utside source. mentioning aung san suu kyi, let's talk about her now, she has spoken out on the issues around the range of muslims crisis, these are some of

the things that she has said. —— around the ringed muslims. —— rohingya muslims. miss suu kyi, have you become an apologist for ethnic cleansing? 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? "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." clearly not aung san suu kyi making

a speech, it wasjonah trying to speak with aung san suu kyi, but he did manage to speak with a very seniorfigure within the did manage to speak with a very senior figure within the burmese army. you can find the bbc reality check article online, looking at some of these claims. jonathan is on the border between bangladesh and myanmar. we asked him to assess the speech. it was a real sense of unreality. all the things she talked about, deep—rooted problems, in racking state, reconciliation, long time development, that is all well and good, but there was no acknowledgement of the scale of what her own armed forces have done in rakhine state. the un has called it ethnic cleansing, anybody who has seen ethnic cleansing, anybody who has seen it would call it that, a deliberate strategy of wiping out muslim villages and driving people

are across—the—board. a00,000 people in the space of three weeks, that does not happen for no reason, every single one has given the same account, the villages were attacked by military, told to leave, chased out, other abuses took place, in some places they have been shot, carrying very little. no acknowledgement of that in the speech by aung san suu kyi. the statement that military operations finished on september five... statement that military operations finished on septemberfive... i heard gunfire when i was in rakhine state on the 7th of september, i saw villages being burned, we watched people doing it under the noses of the burmese authorities. we have seen the burmese authorities. we have seen columns of smoke, across the river, just two days ago, clearly villages are still being burned. fishy in denial, has she cut herself off from reality? this is some of what aung san suu kyihas this is some of what aung san suu kyi has said, we can do that now. this is part of the speech before we hear from this is part of the speech before we hearfrom bbc this is part of the speech before we hear from bbc birmingham this is part of the speech before we hearfrom bbc birmingham ‘s. —— bbc

burmese. we feel deeply for the suffering of all the people who have been caught up in the conflict. those who have had to flee their homes are many, notjust muslims and rakhines, but also small minority groups. 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 those who have stayed. many of aung san suu kyi's international critics were not impressed by that speech. we want to see how it has gone down inside myanmar. the speech, everybody was expecting her to try to distance herself from the military. that is what people were expecting inside

the country. however, when she gave the country. however, when she gave the speech, we all heard this speech, she was rather conciliatory, she was trying to say what she has done as a government and the challenges and also she hardly touched on the a00,000 people who have fled to bangladesh. she did not say much about the military operations that took place in rakhine state, remember, when the un secretary—general made the comment on bbc hard talk, specifically said that aung san suu kyi must try to stop the military operations rakhine state in. but that was never touched. —— military operations in rakhine state. domestically, she had full support from the people, people we re very full support from the people, people were very happy. domestic league people were happy with how confident she was, they we re with how confident she was, they were happy and pleased and happy that she gave a speech in english

because this is a message to the international community, international community, international community, international community should listen to her, because they have been very critical of the rohingya muslims fleeing to bangladesh and their conflicts in rakhine state and she was very quiet about it in the beginning of the crisis. would it have been tenable if she had come out and been critical of the bernie ‘s military, would it have been tenable for her to remain in her role? does she have enough power to issue that kind of criticism? one thing she has is enough support from the people, the full nation was overwhelmingly supporting her. whatever she says, they will support her. however, whether she has enough power to speak out about the military operations in rakhine state, she, as a state councillor, one has to remember, she is not prime minister, she is not president

of the country. so she has very limited power. the world is surprised, one last question, there isa surprised, one last question, there is a lot of outrage outside of myanmar, at the moment but from what you are telling me, there is not much outrage inside myanmar. on the contrary, in myanmar, people are overwhelmed. the way she is conducting these affairs, and... there is very much a kind of sentiment inside the country, there is an anti—muslim sentiment, they do not like the un coming in to try to find out what is happening in rakhine state, they do not want the un fact—finding mission to come in to burma, to try to find out the ground situation in rakhine state, they do not trust the foreigners, they do not trust the foreigners, they trust her, they think that she

can manage these problems, that the country is facing now. from one story of huge significance to another one that is potentially a huge significance, the paris climate agreement, its goal is to hold the global temperature to under 2 degrees above preindustrial levels but the aspiration is to limit the temperature to 1.5 degrees above the industrial levels. next i will show you this paper, it is by nature geoscience, dense affair, it says more ambitious target well, most people would think this will never happen, it says it is not chasing a geophysical impossibility. it may not be out of reach. that's the question, what has changed? we have some help from the bbc science editor. to their surprise, in some years,

these projections are running a bit hot, over estimating the amount of warming you get for a given amount of greenhouse gas pumped into the atmosphere. 2015, two years ago, the world should have been, according to the models, a third of a degree warmer than it actually was. if you ta ke warmer than it actually was. if you take that and project forward, maybe the world has a bit longer in which to tackle climate change. bearing in mind the urgent warnings about getting on with it as soon as possible. according to this study, a little bit longer to tackle it.|j wonder if this is an unhelpful message, given that a lot of countries are under pressure to improve on these accords. there is massive pressure on governments around the world to do more to meet the pledges and go beyond the existing pledges, to act on climate change. if you are sceptical about the need to act on climate change, if you are sceptical about the robust science, that says you do

need to do something about it, you will look at this and think, well, we can take the pressure off, what is the big fuss about. i have the paper here, dense piece of work, it makes clear that the case for acting on climate change is as urgent as ever. more broadly, does this place a question mark about the science, are enough scientists looking at this in the first place to get it right? their question but we are dealing with cutting edge science, science evolves, we think of science as having eureka moment, archimedes coming to a great conclusion, we also think of it being definitive, telling us something absolutely and exactly and it can do that, we know the earth is not flat, it is round. but with climate science, very complicated, 1 million factors at work governing the relationship between oceans and air. biomass, all of that, key

factors. modelling all of that, getting it right in these computer simulations is very difficult and the scientists are the first to admit, they are on a journey, getting better and better, it means, ta ke getting better and better, it means, take a couple of steps forward, one step back, they are not going to get it right all the time and they are open about that. if you are a critic you say they never get it right at all but if you are a realist, you will understand, they are doing their best one step at a time. what about the hurricanes, viewers have been looking at them thinking, can we talk about climate change, should we talk about climate change, should we be talking about climate change, can't believe you have not been asked this question?” can't believe you have not been asked this question? i have tried to find a useful answer, it is a very violent year for hurricanes, hurricane season, that region always gets them. nothing exceptional about the fact we are seeing so many hurricanes, but we are looking like it'll be one of the most violent yea rs record it'll be one of the most violent years record in the atlantic area.

clearly, some climate influences. the basic cooking ingredient for a hurricane is warm water, above 26 degrees. we have had abnormally high temperatures in that part of the world, this year. climate projections say that would be a trend, more warm water, more of the basic starting gas, if you like, to get a hurricane going. what's of other factors at work. sea—level rise, going up three millimetres a year, a big storm surge... add a little bit to how it will overtop defences, that could be critical, but can you say, these hurricanes are the result of climate change? no, scientists do not attempt to do that. hurricanes are a natural phenomenon. 0ur baby made more serious? are they likely to become more severe? probably, yes, is what the scientists are saying. —— are they being made more serious. new research on animals and which ones are more likely to become extinct than

others, the biggest and the smallest of them are in the greatest danger. too hot, too cold, right in the middle is good, with extinction, in terms of size, you better off being in the middle, if you are very big 01’ in the middle, if you are very big or very small, you are in trouble. scientists put all this information on body mass into giant database, 27,000 vertebrates, notjust mammals, reptiles, birds, fish, etc, and they were surprised to find this link, because with large animals it is of the spot with small animals, it seems they too are at greater risk of extinction. with the big animals, fume and hunting, trapping, fishing, affecting things like rhinos and elephants. —— human hunting. human influence. with small animals, quite different, that tends to be loss of habitat. rings like

tiny bats that are very adapted to life in caves, they go out during the night and they hunt, if their forests are logged, then that will have a big impact. a handful of species a year is thought to be a natural rate but we are well above that. hundreds of times, hundreds of times bigger than that. scientists are talking about the sixth mass extinction, which we are currently back to the lead story before we end the programme, earthquake in mexico, 7.1, reports that up to 20 buildings have partially collapsed in mexico city. much of the focus is on mexico city. much of the focus is on mexico city but we understand the epicentres was 50 kilometres south. some of the latest news copy coming through the bbc newsroom, both from bbc journalist and other sources, like reuters and ap, and we will show you the latest pictures that we have. the governor in the state of morale is is saying that a2 people

have died, and that is in central mexico. the same governor has said that at least five dead. —— morelos. that figure has clearly gone up and the figures coming in are evolving. the mexican president, has said that 27 buildings have collapsed in mexico city, that is the latest figure. we spoke without colleague, at bbc mundo, he was hit on the head by something that fell from the roof of the bbc bureau. he is ok but he described thousands coming onto streets because of concerns. writers have confirmed, thousands of people out on the streets of mexico city. we will get more and more information in the coming hours, and you will get it from bbc news. another nightmare weather situation playing out in the caribbean, in com plete playing out in the caribbean, in complete contrast, our weather on

tuesday was settled thanks to a ridge of high pressure. scenes like this across the uk. getting the final cutting here as well, taking advantage of what was a fine day, good sunny spells, importantly, a drier day. none of the big showers around. things will change for some of us during wednesday, this atla ntic of us during wednesday, this atlantic weather system will start to move in. the core of the low— pressure to move in. the core of the low—pressure misses us, to the north, weather fronts low—pressure misses us, to the north, weatherfronts moving, outbreaks of rain for some of us, ahead of it, bringing milder air in across the uk, where it stays dry, it will feel warmer. contrast between dry and wet, for northern ireland, rain turns heavy. into scotland, a little more patchy, in the east, and some rain into the western counties. south—west of england, mostly cold, into devon. for the rest of england and wales, staying dry during daylight hours, sunny spells, and feeling warmer. the weather front is in no hurry to

move the weather front is in no hurry to m ove a ci’oss the weather front is in no hurry to move across the uk, in fact, as we go through wednesday night into thursday, the rain will turn heavier, wet start across much of south—west england, wales, north—west england, south—west scotla nd north—west england, south—west scotland on thursday morning, as it gradually edges further east, ahead of it, behind it it brightens up, but it will feel cooler once again. a lot of us in fine weather once again. succeeding in western parts of the uk, some gales in its brochure. the area of low pressure going into the weekend, nothing to fear from that, most of the energy from this moving north, towards icelander and greenland, we are getting the trailing weather fronts coming in. on saturday, we will notice the weather front increasing cloud in the west and strengthening wind as well, becoming quite blowy here, much of the uk will stay dry.

saturday night and into sunday, weakening weather fronts moving east, noticed the deep area of low pressure, far north, missed us. weakening weather front will go through. some outbreaks of rain, east, and wherever you break out into some sunshine, south—westerly flow, it will feel quite warm. milder than it has been. into next week, a battle underway, between the jet stream, low—pressure systems into the atlantic but coming up against high—pressure in scandinavia. the western side of the uk, some influence from the weather systems coming in, occasional cloud, rain and wind, eastern parts of the uk will stay fine under the influence of high—pressure full. east west split setting up for much of next week. not a wash—out across western parts but closer to low—pressure, some spells of wind and rain, eastern areas, staying

largely fine and the warmest weather asa largely fine and the warmest weather as a result. all of this, warmer, milder air, then we have had recently. indication that things will turn widely unsettled, if not into the following weekend, we will keep you updated. that is something we will watch very closely. tonight at ten: president trump delivers a stark warning to north korea, in his first address to the united nations. he entered the general assembly, which had just heard a warning that the world could be sleepwalking into a war. the speech proved highly divisive, with harsh words for the iranian leadership, but most of his anger was directed at pyongyang's nuclear programme. the united states has great strength and patience, but if it's forced to defend itself of his allies, we will have no choice but to totally destroy north korea. we'll have reaction from the un in new york, where the prime minister and foreign secretary have also

spent most of the day. borisjohnson had boris johnson had to borisjohnson had to deny reports that he's prepared to resign over the government's approach to brexit.
