welcome to bbc news. my name is mike embley. our top stories: as world leaders meet for a special un summit on climate change, the teenage activist greta thunberg greets them with a furious attack. how dare you?! you have stolen my dreams and my childhood with your empty words. the massive operation to bring thousands of tourists back home after the collapse of thomas cook. defending himself against accusations of abuse of power, donald trump denies pressuring ukraine's president to look into unsubstantiated corruption allegations againstjoe biden. prince harry, meghan and their baby son archie are in south africa for their first overseas

tour as a family. at the united nations in new york, the teenage activist greta thunberg has made a scathing attack on world leaders gathered for a special summit on climate change. around 60 heads of state attended. some very prominent figures stayed away. she accused them of betraying her generation through their inaction on global warming, and said young people would never forgive them if they failed to do more. this from our north america correspondent nick bryant. a sweltering september scorcher in new york city. not much sign of autumn here. and it hasn'tjust been a long summer, but north of the equator, the hottest ever on record. so today, at the riverside headquarters of the united nations, an urgent climate action summit, this global body once more sounding the alarm. the world is losing the race

against climate change. applause in this air—conditioned auditorium, the heat came from the 16—year—old swedish activist greta thunberg, the un hoping to harness what is being called the greta effect — her ability to mobilise the young and to shame the old. and, my, how she did that today. this is all wrong. i shouldn't be up here. i should be back in school on the other side of the ocean. yet you all come to us young people for hope. how dare you?! you have stolen my dreams and my childhood with your empty words. you are failing us. but the young people are starting to understand your betrayal. the eyes of all future generations are upon you, and if you choose to fail us, i say we will never forgive you.

applause and cheering was their applause a form of apology? reporter: mr president. the world's most powerful adult only briefly stopped by. greta thunberg watched from the side, scowling, as he arrived. he didn't address the summit himself. he is withdrawing america from the paris climate change accord. and soon he took the chair at a rival event organised by the white house on religious persecution. other international leaders have come here with new pledges to curb emissions. only nations with aggressive plans were allowed to speak. but even those commitments won't be enough to keep temperatures from rising to dangerous levels. but every world leader today was completely upstaged by a teenager with a furious speech that will echo down the generations. nick bryant, bbc news, new york. the summit closed for the day a short time ago, the un

secretary—general telling delegates he was encouraged and inspired by the pledges of action, particularly from smaller countries who have caused the least damage to the climate. you understand the climate emergency is the fight of our lives, and for our lives. i thank young people around the world for leading the charge, and holding my generation accountable. we have been losing the race against climate crisis, but the world is waking up. pressure is building, momentum is growing, and action by action, the tide is turning. today, in this hall, the world saw clear ambition and concrete initiatives. let's get more on this. our correspondent nada tawfik is at the un in new york. president trump or at least white

house staff must have been aware of the presence of greta thunberg. they organised another event at the un, it seems, specifically to keep the president away from the climate summit. do you get any sense from them that they feel the ground is shifting politically on climate change? i think absolutely, shifting politically on climate change? ithink absolutely, and i think the fact that we did see president trump stopping by the climate action summit unexpectedly really speaks to that. for one, we have seen millions of young activists protesting on this issue. we are seeing here in the united states, even at the summit, you had numerous cities coming forward, showing how they see this as a defining issue of the time that they need to respond to. and so i think president trump, by stopping by the summit, it was almost an acknowledgement there of this being acknowledgement there of this being a big issue. but at the same time, i don't think it is going to change the united states's approach, and certainly we heard from a lot of

environmental groups that the summit did not go far enough. the secretary general afterwards said that some 70 countries had committed to carbon neutrality by 2050, had agreed to up their commitments under the paris climate accord by 2020. but still they said countries hadn't gone far enough. so certainly for greta thunberg and other activists this was just a starting point to more action that they hope to see down the line. there are more events to come at the un on tuesday. what hopes from those? well, we are already seeing that the heightened tensions between iran and the united states is coming up. so for example, president trump today telling reporters that he plans to address iran in his major speech to the un general assembly on tuesday. and that comes, really, after a meeting today by germany, the uk and france

which put the blame for the attacks on the saudi arabian oil fields directly on iran and said that it was now time for tehran to start negotiating a new agreement that dealt with notjust negotiating a new agreement that dealt with not just the negotiating a new agreement that dealt with notjust the nuclear profile but also their ballistic missile programme and regional issues. so this is certainly going to bea issues. so this is certainly going to be a big issue when the uk prime minister, borisjohnson, to be a big issue when the uk prime minister, boris johnson, meets president macro rouhani tomorrow in a bilateral meeting and we will see what the rest of the week brings as world leaders gather to discuss these tensions. let's get some of the day's other news: according to human rights activists, almost 500 people have been detained in egypt in the past few days after protests against government corruption. demonstrations were reported in cairo, alexandria and several other cities on friday night, and in the port city of suez on saturday evening. authorities have not released an official number of arrests. the supreme court in london will rule on tuesday morning on the legality of prime minister borisjohnson‘s decision to suspend parliament. ministers say the five—week

suspension, or prorogation, is not a matter for the courts. mrjohnson‘s opponents argue he went for a longer suspension to limit scrutiny of his brexit policy. families of the 346 passengers who died in two separate crashes of boeing 737 max aircraft are being offered almost $150,000 each. the aircraft maker says families can claim the compensation without waiving their right to sue. boeing's entire fleet of around 500 737 max planes have been grounded since march following crashes in ethiophia and indonesia. thousands of stranded thomas cook passengers will be repatriated on tuesday as the rescue operation continues into its second day. holidaymakers were being brought home amid questions over the multimillion—pound sums received by the bosses of the firm prior to its collapse. it is the largest repatriation to happen in peacetime. let's hear from some of them.

and they've stopped coaches coming in and letting people go home, because they've not paid this money, but i've already paid. yeah, we're absolutely gutted. we've looked forward to this for a long time. still hoping to get on a thomas cook flight. they're still accepting bookings and flights until late last night. ijust had a sixth sense at 2:00am this morning, got up, checked the website, and that's when it hit the fan, basically. what's happened is our thomas cook representative has walked out. we're left in the dark. thomas cook has not paid the hotel yet, and they've warned us that they've not been paid. we're left in the dark. the first we heard about it was waking up this morning for the bus that we were getting into corfu town, near the airport.

marc casto is the vice chair of the american society of travel advisors. he is not in the us at the moment, but manila. what are you making of all of this? it is truly incredible. thomas cook is one of the large global players and the impact around the world is being felt. there is an estimated 600,000 travellers both current and future who will be impacted by this event. yes, and what about this impact around the world? we are used to in the uk travellers having some kind of safety net. that is not necessarily the case elsewhere. that is correct. the operation by the cia is correct. the operation by the cia is repatriating everyone to the united kingdom, but it is only to those people who originated in the united kingdom. for those with a separate profile, it is not affecting them. and we have just discovered that condor airlines will be repatriating people back. but there are other regions as well. we are having some problem with the

sound feed, i hope you can hear me 0k, and perhaps the sound will get better if we stick with it. so essentially people are having to go through their credit card or their travel insurance if they have got it. essentially people need to keep their paperwork. yes, i am sorry about the sound but i hope it improves. yes, travel insurance is the first and foremost avenue of success the first and foremost avenue of success for travellers who are impacted by this. if they have it they should use it and contact the supplier. 0ther they should use it and contact the supplier. other situations are that they can contact the credit card company for at least some form of restitution. that is not a global standard. it does apply for some regions, and others. for instance in the united states we have a credit ca rd the united states we have a credit card billing app that can compensate some people for that. is it likely that people willjust be stranded? many people are being stranded without any recourse to get home and u nfortu nately without any recourse to get home and unfortunately there is no real option for them. they may have no choice but to buy a ticket to get home. and hope to get the money back? hopes to get the money back. hope is a terrible strategy as it comes to this scenario here and if they have any avenue with travel insurance if they have purchased

that, or their credit card may be, but outside of those they may be com pletely but outside of those they may be completely in a terrible spot. are using lessons to be learned from all of this? well, the first and foremost one is, we have mentioned it, iama foremost one is, we have mentioned it, i am a big advocate of travel insurance. both the american society of travel agents as well as my company, flight centre, are always recommending travellers take it because you never know when the inevitable could occur. and we don't wa nt inevitable could occur. and we don't want our holidays to be spoiled by this. so i would strongly recommend that travellers do engage with travel insurance. thank you very much. pleasure, thank you very much. stay with us on bbc news. still to come: more problems for cruise liners as another european city, this time cannes, says it will impose restrictions on the most polluting ships entering the resort. ben johnson, the fastest man on earth is flying home

to canada in disgrace. all the athletes should be clean going into the games. i'm just happy that justice is served. it is a simple fact that this morning these people were in their homes. tonight, those homes have been burned down by serbian soldiers and police. all the taliban positions along here have been strengthened, presumably in case the americans invade. it's no use having a secret service which cannot preserve its own secrets against the world and so the british government has no option but to continue this action even after any adverse judgement in australia. concorde have crossed the atlantic faster than any plane ever before, breaking the record by six minutes. this is bbc news. the latest headlines:

the teenage climate campaigner greta thunberg has told world leaders that her generation will never forgive them if they fail to combat climate change. a huge operation is underway to bring thousands of tourists back to britain after thomas cook collapsed, a process that will take two weeks. let's return to the special climate summit in new york. the un secretary general says the race to stop a climate emergency can still be won. but the teenage climate campaigner greta thunberg was not so optimistic. she accused world leaders letting young people down. the bbc‘s laura trevelyan has more. welcome to the united nations in new york where their teenage climate activists greta thunberg really caused quite a stir when she accused world leaders of stealing her childhood and her dreams by failing to act on climate change.

joining me now to talk about all of this is a 14—year—old timothy. timothy you are an advocate for the united nations children's fund on the environment, thank you for being with us. you're welcome. tell me, what's your reaction to greta thunberg's speech? i'm so proud of her, because i think she delivered a wonderful and inspirational speech, and i think world leaders are more inspired by her speech. what impact is climate change is having on yourfamily? back in 2016, we faced a cyclone which struck fiji, and it was cyclone winston, it destroyed our homes, ourfarms, and it washed away our crops, and also, to our school, it was totally damaged, and some of our, some of the houses in our village were blown away.

timothy, is climate change something that you worry about, because you see the effects all around you ? yeah, climate change is really happening, and that is why i am so worried, and also i am worried about the future generations. we might suffer more than us — they might suffer more than us, because we have less time, so we need to work together to build a better planet for our future generation. timothy, you have been here at the united nations all weekend, you have seen all these world leaders, today there were lots of pledges, but do you feel that the older generation is doing enough on climate change? i hope so, because i have seen that many people from different countries, many leaders

from different countries have gathered together and they have said different speeches, but i want to say that speeches won't solve the problem, but walk the talk is more effective. timothy, thank you forjoining us so much on bbc world news. that's timothy, timothy is just 14 years old, but he lives in fiji and he sees for himself the effects of climate change, so that is the voice of a generation, and the frustration that he and greta thunberg and other teenagers feel on the inaction of climate change, we saw the come right here to the united nations, and they told the grown—ups you need to do better. for much more on the battle to tackle global warming don't forget to check out our website. you'll find an article on the latest scientific research on temperature

and sea—level rises. and even our climate change food calculator , where you can figure out the carbon footprint of your diet. that's at bbc.com/news. a day after admitting that he talked to ukranian president volodymyr zelensky about investigating unsubstantiated corruption allegations against former vice presidentjoe biden and his son president trump has doubled down. arriving at the un he had this to say about the call which has come under such scrutiny. we had a great conversation, the conversation i had was largely they failed. joe biden did what they would like me to do, but he didn't

do it. david willis is our north america correspondent. essentially what he was suggesting was the joe essentially what he was suggesting was thejoe biden should go to the electric chair. the quote was if this happened to a republican, he would be subjected to the electric chair but it's emerged over the weekend, mike, that president trump in the course of that telephone conversation with the ukrainian resident sought to raise the issue with him of investigating his rival, joe biden. at the time of that call, the white house, we now know, was sitting on some $215 million in aid that had been approved by congress but not yet sent to the ukraine. joe biden has said that all amounts to an use of residential power. president trump denies this but is taken to twitter today to question the motives of a whistleblower reported his concerns about the same

conversation it appears to his superiors and he said on twitter, is he on our countries aside, the suggestion being this person could be some sort of traitor. the white house is not ruled out releasing a transcript of the telephone conversation with volodymyr zelensky although there has been strong advice from members of the administration and president trump's aides and supporters not to do so. the white house is thought to be blocking the release of that whistleblower‘s report from getting to congress as is the norm in these circumstances. so much as swirled around president trump, it might well have brought down another president, doesn't seem to touch him. how significant does this seem to be? i think it is quite significant, mike, for the simple reason that the democrats seem to be hardening their approach to this

issue of impeachment. they had been in many cases sitting on defence. certainly the house speaker nancy pelosi feared that launching impeachment proceedings could backfire on the democrats, harm their chances in the elections next year but over the weekend, we saw adam schiff, the house intelligence committee chairman and a man who had previously been opposed, like nancy pelosi, two impeachment proceedings, come out and say he was now in favour. he said the rubicon had been crossed. we also heard from senator elizabeth warren, one of the frontrunners for the democratic presidential nomination saying that congress would be complicit, as she put it, in all this if it failed to investigate. we willjust have to wait and see, democrats are due to meet tomorrow afternoon but it seems as though attitudes are hardening amongst their ranks.

the duke and duchess of sussex have arrived in cape town, at the start of a 10—day tour of southern africa. they are visiting one of the city's townships which has the highest murder rate in the country where meghan spoke out against violence against women , and praised those who had, in her words, stood up for what was right. 0ur royal correspondent nicholas witchell sent this report. they both know this trip needs to be a success after recent missteps and negative headlines. no time to waste, then. harry and meghan dispensed with a red—carpet welcome and came straight to a township. the exuberance of the welcome masks the fact that nyanga township has the highest murder rate in south africa. the couple had come to show their support, for a refuge for women and children. and amid all the hugs and the handholding was the serious message — violence against women is a huge problem here. and meghan marked out her determination to be heard. while i'm here, with my husband, as a member of the royal family,

i want you to know that, for me, i am here with you as a mother, as a wife, as a woman, as a woman of colour, and as your sister. and that, of course, was very much meghan — articulate, passionate and about a subject about which she cares very deeply. it underlined the sussex's determination to do things their way. we're so excited! another small example — although they've brought their son archie with them, there are no current plans to make any appearances as a family. nicholas witchell, bbc news, cape town. the mayor of cannes says he'll impose restrictions on cruise ships coming to the french resort. the new rules mean that passengers from polluting liners may not be able to set foot on land.

it follows a similar ban imposed in the italian port of venice. the bbc‘s tim allman has the story. when you think of cannes, this is probably the sort of thing you have in mind. luxury, wealth and opulence. but some here are worried that along with the glamour there is pollution and increasingly dirty air. 0ne pollution and increasingly dirty air. one possible culprits, the huge cruise liners that visit the city every year. a new is being imposed on the self that they emit. if they are not clean enough, their passengers may not be able to disembark. translation: it's not about being against cruise ships, it's about being against pollution. we will no longer accept two buses and cruise ship passengers on the ground coming from polluting cruise ships. nearly 400,000 such passengers come to cannes each year and some of the ships are older than others but their owners insist they

are sticking to the rules. you at the end of the summer we will go into our maintenance cycles so the ship will be out of service for two 01’ ship will be out of service for two or three week and we will implement the changes to the engines to make them comply with the latest development regulations. venice is another city that's introduced new restrictions on cruise ships. that and was prompted by a liner crashing into appear but environmentalists have long voiced concerns about the pollution and erosion these ships can cause. the band and cannes begins in january 2020 and can cause. the band and cannes begins injanuary 2020 and already beautiful place that may soon be just that little bit cleaner. tim allman, bbc news. there is more beyond bbc website. and you can get in touch with me and most of the team on twitter.

hello once again. while some spots, particularly northern and eastern britain, started monday decently enough, eventually weather fronts piled in from the atlantic. here we are on tuesday, you get the sense we may well be in for something of a repeat performance. in fact, tuesday could be one of the wettest and windiest days that many areas will have seen for quite some time. in the first part of the day, it's the southern half of britain that's likely to see the very worst of the conditions on offer. as i take you on through the morning and on into the afternoon, you'll notice some of those really dark blues and greens gradually work their way ever further towards the north and it will be gradually a fairly slow process as well. that's why we think some spots widely could see 30—40 millimetres of rain, others could get up to 70 millimetres of rain.

some of the gusts, 40, possibly even 50 miles an hour in exposed locations. just to give you a sense of the spread of those gusts, even into the north of scotland, where you don't see the very worst of the rain, it will be a windy day. and then later on we may welljust ramp up some rain and some stronger winds yet again. initially into the south—west, but then widely across the southern counties of both england and wales. and on what is not going to be a particularly cold night given the amount of cloud around on the strength of the wind as well. here we are on wednesday, and once that side of the feature has worked its way off to the near continent, actually wednesday is going to be one of the quieter days of the week. once that wind and rain has cleared away from east anglia and the south—east, then there is a fair amount of dry weather, yes, there will be a spotting of showers in north scotland, not so much wind. you may feel like standing around

in it, but probably not on tuesday. here we are on thursday. if you've seen the forecast in recent days, these forecasts have sped up, it looks like they would hang around for the first part of friday. bar the far north—eastern quarter of scotland, it looks like they clear the eastern shores of the british isles, leaving behind a drier prospect, albiet fairly late in the day for some. and then we may gang up some of those showers to western areas to give the odd longer spell of rain. and all the while, the wind is quite a significant factor on the day on friday. so essentially, it's a day of sunny spells with some showers. but some of those showers ganging together on many fronts to give some longer spells of rain. and again we are darkening out some of these blues so i would be not at all surprised if you heard the odd rumble of thunder in the heaviest of those downpours. the top temperature of the day, 18.

this is bbc news. the headlines: teenage climate campaigner greta thunberg has delivered an angry address at the united nations climate change summit in new york, where she accused world leaders of failing young people. she said that her generation will never forgive them if they fail to combat global warming. a huge two—week—long operation is under way to bring thousands of tourists back to britain after thomas cook collapsed. it comes as the uk government requests an investigation into the travel company's bosses over the firm's closure. there has been growing criticism over executive salaries at the company. donald trump has defended enquiring about his presidential rival joe biden during a call with the ukrainian president volodymyr zelensky. mr trump, though, denied that he tried to press the ukrainian leader into opening an investigation into unsubstantiated corruption allegations against mr biden and his son.
