aramco oil refinery. hello and welcome to bbc world news. a day of protest by millions of young people to demand action against climate change is heading towards a finish. from australia to india, europe and the united states, they took to the streets to demand action. their inspiration, teenage activist greta thunberg, told crowds in new york "we will make them hear us. our first report this hour is from the bbc‘s nick bryant. don't let our people die! climate change is not a lie! the protests followed the sun. from the low—lying pacific islands to drought—ridden australia, from the streets of south africa to the brandenburg gate in berlin. the children of the world, the inheritors of our climate change crisis.

what do we want? climate justice! when do we want it? now! young voices speaking with passion and urgency, because theirs is the future that's at stake. considering we have such a short amount of time to turn this issue around, it's vital that young people are at the forefront of this conversation because they will be impacted more than anyone else. what the youth can do is talk about the problem and make noise about it and demand it from the people who can create a change. there is no time. time is up, time is running, and this is our last chance to do something. in westminster, a place more commonly filled with brexit protesters, was thronged of people united in concern for the planet. and there were similar scenes across britain — belfast, bristol, birmingham, smaller towns and rural communities. as yet another demonstration took shape in new york, we spoke to the 16—year—old activist greta thunberg, who's become the insistent voice of this restless generation. did you ever think it could end up

with something like this? my dad woke me up today, and he said, "it is massive, you need to see these pictures." and then i went up, and i just saw these pictures, and i couldn't stop looking, because it was just so overwhelming. and you cannot believe it's real. this is not only my voice, this is the voice of millions of people around the world. but i think it is because we are young, and we are the ones who are going to have to live with this in the future. then she saw for herself on the streets in manhattan the multiplier effect of this movement. in this most global of cities, more than a million kids had been given permission to skip class, to make their voices heard. what do we want? climate justice! when do we want it? now! this extraordinary mobilisation really feels like a milestone moment, a day maybe we'll talk about for decades to come.

the question is whether this climate change activism will translate into climate change action. you're here marching today. what are you planning to do for the rest of the year? i'm going to eat less meat, i'm going to recycle as much as i can. i'm going to everyone around me aware. i'm going to do try and do what is best for me as well as best for the earth. it felt like the white house was in a different century today. donald trump, the president who's taking the united states out of the paris climate change accord, welcoming the australian prime minister, scott morrison, a leader who once proudly brandished a piece of coal in his parliament to emphasise the centrality of fossil fuels to his country's economy. the children are demanding that it's time to put the environment first. to some, this will be a confronting reminder of how successive generations of adults have let down the young. but in this planetary day of action, these children can tell their children that they marched. nick bryant, bbc news, new york.

incredible numbers there. just a short while ago, greta thunberg, who you saw there, has been speaking to protesters in new york. we are not in school today. and this time, we are not alone. we have some adults who are not at work today either. and why? because this is an emergency. our houses on fire —— houseis emergency. our houses on fire —— house is on fire. and it is notjust the young people's house, we all live here. it affects all of us. and we will notjust stand aside and watch, we are united behind the science, and we will do everything in our power to stop this crisis

from getting worse. even if that means skipping school or work, because this is more important. climate protester greta thunberg. friday's protests come ahead next week's un climate change summit in new york, where world leaders will discuss how best to address global warming. here's our science editor, david shukman. a stark reminder of what the protests are all about. for these people on a pacific island, it is a matter of life and death, whether their country can actually survive in future. as the planet heats up, the seas rise, and for millions of people in low—lying communities, the threats are already extreme and are set to become much worse. i saw for myself two

weeks ago how the ice of greenland is melting, adding to the level of the oceans. and scientists fear that more melting will follow. all the time, human activities keep adding to the problem. this is indonesia right now. the fires are immense, like in the amazon, and they release carbon dioxide into the air, and that rises temperatures even faster. the challenge is that the world is on a course towards dangerous levels of warming. the global average temperature has already risen by one degree over the last 150 years or so. and scientists say a 1.5 degrees is the maximum safe level. anything more risks a range of damaging impacts. but we are currently heading towards three degrees rise by the end of the century, and that is even evolve the climate promises made by governments

are kept, if nothing is done, some fear an increase of four degrees would potentially have catastrophic results. so what can be done? well, the un wants more renewable energy like wind turbines. today, the british government approved hundreds more. there will cost far less than expected. in the same way, the price of solar power has fallen, and the un is hoping the summit next week will see new promises to build more installations like this. but hard facts remain. much of the world depends on coal, the dirtiest of the fossil fuels. and moving away from it is difficult. leaders, including president trump support it. there will be a struggle ahead. david shukman, bbc news. and you can find more in—depth coverage of the climate protests around the world on our website. and if you've been wondering whether individual actions and choices can make any difference in the face of climate change, our chief environment correspondent, justin rowlatt, has written a handy guide. just go to bbc.com/news.

almost 300 people were killed when it collapsed unleashing a torrent of mining waste onto a nearby town. us president donald trump has described a whistleblower‘s accusations that he made a promise to a foreign leader as "a political hackjob." some reports allege that mr trump asked ukraine's new president, volodymyr zelensky, to investigate the son of presidential rival joe biden, who previously served on the board of a ukrainian gas company. in return, ukraine would continue to receive us military support. speaking earlier today, president trump said he'd done nothing wrong. i have had conversations with many leaders that were always appropriate. always appropriate, at the highest level, always appropriate. and anything i do, i fight for this country. i fired so strongly for this country. it is just another political hackjob. somebody ought to look intojoe

biden‘s statement, because it was disgraceful when he talked about billions of dollars that he is not giving to a certain country and there is a certain ossicular is taken off the case. —— prosecutor, someone taken off the case. —— prosecutor, someone ought to look into that, but he wouldn't because he's a democrat. i don't know the identity of the whistleblower, but ijust know it's a part is in person, meaning it comes up a part is in person, meaning it comes up from another party. but i did it was a totally appropriate conversation. —— i think it was. aleem maqbool has more on the story from washington. nothing officially is being given at the moment at the moment, even who this foreign media was that —— foreign leader, where this conversation took place. what an intelligence official said in his formal complaint was he listened into a coal donald trump had with a foreign leader in july into a coal donald trump had with a foreign leader injuly and was so troubled by what he heard that this was part of de la aja complaint,

actually. what sources familiar to this complaint have told journalists here is that it was, a conversation between donald trump and the ukrainian president, volodymyr zelensky, where he was suggesting this investigation notjust intojoe biden's son, but intojoe biden himself and the demands thatjoe biden made of ukraine should be investigated. and as you had there, he said ifjoe biden wasn't a democrat, the media here would be making a cry about that being investigated. now, it does appear that there is some truth in the fact that there is some truth in the fact that he did bring upjoe biden with ukraine in the past, there were already suspicions he had been doing that. but that it was essentially admitted by rudy giuliani, the attorney for the president, that he had mentioned an investigation into

joe biden to ukraine, but donald trump is saying there was nothing inappropriate even in that. thank you aleem maqbool. a woman who claims she was abused by britain's prince andrew as a teenager, has given her first television interview about the allegations. virginia roberts giuffre told nbc news in america, that she was "trafficked" to prince andrew, whom she described as "an abuser". her allegations first came to light in court papers lodged against the billionaire businessman jeffrey epstein, who'd been accused of trafficking underage girls. buckingham palace has strongly denied that the duke of york had any form of sexual contact, or relationship with ms roberts. 0ur royal correspondent jonny dymond has more. the prince, the teenager and the socialite. now an adult, for the first time outside a court, virginia roberts alleges she was trafficked to prince andrew. the link is this man — jeffrey epstein, a convicted sex offender, now dead.

this is bbc news. the latest headlines: climate activists of all ages have gathered in new york as a day of action reaches its climax. millions have taken part around the world. one of the events driving fears about climate change has been the fires taking place in the amazon. the brazilian president, jair bolsonaro, is expected to address the issue in a speech to the un general assembly next week. despite government claims the worst is over, fires continue to plague the amazon region of brazil as will grant reports from the state of para. with people turning out across the world in cities for the climate strikes, this is a visual representation of what is motivating them to take to the streets. this area is one part of around 1600 football fields of amazon forest, now just charred football fields of amazon forest, nowjust charred and blackened by the wildfires. and of course after

the wildfires. and of course after the fire rages through this area, the fire rages through this area, the trees simply can't do their basic functions anymore. they can't convert the carbon dioxide to oxygen, they cannot recycle water into the atmosphere and the result, as you can see around me, is environmental destruction on a massive scale. for those who suggest that the crisis in the amazon is over, that this isjust that the crisis in the amazon is over, that this is just one area of more than 111,000 areas of fire currently thought to be raging according to brazil's space research institute and actually there is very little to be done when this is the result of the flames. it was 1600 football fields. such a vast space. what is that in hectares, or... we are blind about

amazon, we are blind. we need to understand what it is. it is a 61% of brazilian territory. it is bigger than europe, the territory, and we have the biggest source of water in the world. we be ——we have a big responsibility. we have to look at the forest, we have to look at the amazon as not only the future, it the present. its the past. well, this marks the fire line between an area that was absolutely destroyed and scorched by the wildfires and pa rt and scorched by the wildfires and part of the forest that wasn't yet reached, that remains green. and the volunteer firefighters have come out to this point using gps equipment because there was still smouldering roots beneath the trees that they wa nt to roots beneath the trees that they want to put out to ensure the fire didn't go any further. it has already consumed a vast swathe of this part of the amazon and that particular group of people are doing

this in their spare time, they are doing it with very few resources and they say that really, in a dry season like this, it is incredibly hot and it is very, very dry, even the smallest spark could set this off again. we have been talking about the amount of climate activists that took to the streets around the world. this is from bogota. this is in one of the squares in bogota, holding the signs. 0ne says trees' lives matters. this is various cities of young people coming out to ask for leaders to make a move on climate change. the school day is well over but the young people are still there and continue to try and garner attention right now.

the war of words is intensifying between the us, saudi arabia and iran, after last week's drone and missile strike on two saudi oil facilities. the iranian foreign minister has tweeted that riyadh wished to fight iran, "to the last american". that's a response to comments by the us secretary of state, mike pompeo, who claimed iran was threatening war. 0ur security correspondent, frank gardner has sent this report from saudi arabia. twisted, burnt and blackened by fire — the aftermath of multiple drone and missile strikes across 19 targets, hitting the very heart of saudi arabia's oil industry. this was the moment last weekend when the attack halved output and sent oil prices soaring. today, the government allowed the media into this normally closed site. it wants the world to see the destruction it's blaming on iran, which denies responsibility. the damage was clearly

spread over a wide area. this is abqaiq, the largest oil processing plant in the world, and it got hit in the early hours of saturday morning. the saudis say they're confident they can restore production by the end of september. what they can't say with any confidence is they can prevent such an attack happening again. repair teams are still working around—the—clock. this isn'tjust about patching up the holes, it's about restoring saudi national pride and prestige in the global economy. over in the saudi capital, riyadh, life goes on as normal, so i asked people what they made of these attacks. "these are just acts of terrorism against saudi arabia from its enemies," said this man, "but we'll guard against it and overcome it. " but this man said he was both angry and afraid. this attack has shocked saudi arabia

and revealed its vulnerabilities. that's perhaps why one week on, it is still no no hurry to retaliate. now, the story of a man who goes to incredible lengths to bring closure to the families of drowning victims. diver keith cormican and his team of volunteers have reunited more than 30 missing bodies with their loved ones. but for mr cormican, it's notjust a profession, his diving holds personal meaning as well. whenever we locate a drowning victim, it is tough to explain. it is very sad and yet we are happy to be able to give that closure to these families. just last week, i was able to recover my 30th drowning victim. that is a lot of families, a lot of people affected by this. the body they discovered out in the water is the body of... the phone rang and my husband pulled over and instantly i knew they found him. being able to help these families when they are in the darkest moment

of their lives, having their loved one in the bottom of the lake. i can't imagine what the families go through. you just have to be ——it has to be horrible to deal with. through. you just have to be ——it has to be horrible to deal withm does give you peace to know that he is going to be out of that lake. in august of 1995, we out for a drowning in our county. the fire department won't really trained in this kind of environment. they were caught ina this kind of environment. they were caught in a current, not breathing. i'm sure we were able to revive the ones does make the one firefighter and the other one they transported to urgent care. the families had to make a decision to get him off life support and that was my brother. it was the following year when i decided to switch gears in my life.

we are not always successful and by far, those of the toughest ones from having to walk away from, not able to find a drowning victim is the worst. we have been able to give that closure so it is very gratifying to give them that. you can reach me on twitter —

i'm @bbcnuala. i would love to hear from you. stay with bbc. hello. friday brought a lot of sunshine to a lot of places across the british isles and i don't think we're going to see a radical change for many areas on saturday. simply because the overall pattern is pretty similar. high pressure in the continent, low pressure in the atlantic, therefore, we are still tapping into this run of south—easterly airs and quite strong winds at times, up from the mediterranean, through the near continent and into the heart of the british isles. that is dry air so we are not seeing an awful of cloud for most us just yet. the exceptions to that, the northern ireland ‘s and later in the day, the first signs of the atlantic front trying to cloud things over in the south—west. an onshore breeze from the north sea will keep the eastern coast down at 16 or 17 but come inland, 20 plus is

widely available. through saturday night and on into sunday, the first signs of the change and the high—pressure drifts further away and income is different from the atlantic. that will set the tone for sunday. before the persistent rain arrives, we will have some quite sharp showers and maybe the odd under storm gradually drifting up the spine of the british isles and then the front makes progress away from the western fringes ever further towards the north and east and to avoid that rain, something quite heavy will have to be that further north and east. still, the temperature in excess of 22— 23 degrees or so towards the east but fresh air is coming in from the atla ntic fresh air is coming in from the atlantic and that sets the tone for the start of next week. monday, not too bad. the rain from sunday gradually eventually clearing away from the far north—eastern corner of scotla nd from the far north—eastern corner of scotland and then a lull in proceedings and then late in the day, more signs of the next belt of wet and windy weather pushing in from the atlantic into the south—western quarter of the british isles. not cold by any means but the

temperature is back on what we have seen at the weekend. and then as we move from monday into tuesday, that area of low pressure becomes pretty resident out towards the western side of the british isles and at times, through the next few days, it will be throwing these belts of cloud and wind and rain across many parts of the british isles. it is all going to be quite mobile so it will rain persistently ——it won't rain persistently anywhere for the whole day but while that rain is around, you will notice it, this is not showers, belts of rain are moving in from the atlantic. there is not a great deal of difference as we go from tuesday into wednesday. low pressure still out towards the west of the british isles, still with these weather fronts working their way in with these weather fronts working theirway in and with these weather fronts working their way in and at times, some really quite strong winds. quite a change on the way.
