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 bbcs nick bryant. Dont 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 thats at stake. Considering we have such a short amount of time to turn this issue around, its 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, whos 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, its massive, you need to see these pictures. And then i went up, and i just saw these pictures, and i couldnt stop looking, because it was just so overwhelming. And you cannot believe its 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 well talk about for decades to come. The question is whether this Climate Change activism will translate into Climate Change action. Youre here marching today. What are you planning to do for the rest of the year . Im going to eat less meat, im going to try and recycle as much as i can. Im going to everyone around me aware. Im 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 whos 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 countrys economy. The children are demanding that its 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. 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 house is on fire. And it is notjust the young peoples 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. Rising sea levels attributed to Global Warming are threatening entire communities along west africas shoreline. An estimated 5 Million People live along ghanas atlantic coast. The Coastal Region is a significant contributor to the countrys economy. Many homes in the eastern volta region have been destroyed by tidal waves in recent years. The bbcs thomas naadi reports from the keto district where 100 homes have been washed away. This village is in southern ghana. This village is in southern ghana. This unique location has made it home to the Destructive Force of tidal waves. This was the village into thousand and i6. Tidal waves. This was the village into thousand and 16. The region was originally five kilometres away from the sea for decades, before the destructive impact of the ocean. Three years ago, it was a very vibrant fishing village. Now look at it. Everything is completely gone. Tidal waves have taken parts of the village with it into the sea. Many have lost their property, and all of their belongings. Celestino and her family still live here. Translation we need help. We dont have a place to sleep, and when it comes to relocation, we are afraid because we will leave ourjobs. These waves lapping the shores are washing away the sea sand, chipping the coastline. It is a long process, but Global Warming is accelerating this. Residence here tell me they fear losing everything. We are afraid. What are we going to eat . This is a mega challenge facing challenges on the west african coast. Communities living around the coast. Communities living around the coast will lose a lot, their cultural values, and they will need to relocate citizens from these coastal areas. It is a problem that is not happening only to them, it is happening all over the world. Authorities in ghana have installed levies as sea defence. The immediate plan is to protect the coastline through the sea defence project. The medium to Long Term Plan will be relocation, to send them away from the area. That is why the immediate challenges we are facing in terms of levies and relocation and finding an alternative livelihood for them. The disappearance of this village is a strong indication that if nothing can stop the waves, it wont be long before surrounding towns are entirely wiped off the map stop thomas naadi, bbc news in southern ghana.

In a rare sign of dissent in egypt, small groups of protesters have gathered near Tahrir Square in cairo, to shout Anti Government slogans.

Officers said the two firms had worked with falsified documents that said the dam in minas gerais state was stable. Almost 300 people were killed when it collapsed. Us President Donald Trump has described a whistleblowers accusations that he made a promise to a foreign leader as a political hackjob. Some reports allege that mr trump asked ukraines new president , volodymyr zelensky, to investigate the son of president ial rival joe biden, who previously served on the board of a ukrainian gas company. Mr biden is calling on the white house to release the full transcript of the call, but speaking earlier today, President Trump said hed done nothing wrong. I have had conversations with many leaders that were always appropriate. I think scott can tell you that. Always appropriate, at the highest level, always appropriate. And anything i do, i fight for this country. I fight so strongly for this country. Its just another political hackjob. Somebody ought to look intojoe bidens statement, because it was disgraceful, where he talked about billions of dollars that he is not giving to a certain country unless a certain prosecutor is taken off the case. Someone ought to look into that, but he wouldnt because hes a democrat. I dont know the identity of the whistleblower, but ijust know its a partisan person, meaning they come from another party. But what can say was it was a totally appropriate conversation. Lets get some more details from aleem maqbool. Nothing officially is being given at the moment at the moment, even who this foreign leader was, where this conversation took place. What an intelligence official had said in his formal complaint was he listened into a call that donald trump had with a foreign leader injuly and was so troubled by what he heard. This was part of a larger 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 bidens son, but intojoe biden himself and the demands thatjoe biden made of ukraine should be investigated. And as you heard there, he said ifjoe biden wasnt 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 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, who is an attorney for the president , that he had mentioned an investigation intojoe biden to ukraine, but donald trump is saying there was nothing inappropriate even in that. Thanks, aleem maqbool. Stay with us on bbc news, still to come 3 million said they were interested in attending, so why did so few actually make it through to area 51. Thenjohnson, the then johnson, the fastest man thenjohnson, the fastest man on earth heads home to canada in disgrace. Then johnson. I am happy thatjustice 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. Its 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.

The United States is to send troops and Missile Defence systems to saudi arabia and the united arab emirates, in response to last weeks attack on saudi arabias oilfacilities. Washington has blamed iran for the attack although the iranians insist they were not involved. A us spokesman said President Trump had given his approval in response to requests for the support. Our security correspondent, Frank Gardner has been shown around one of the refineries that was severely damaged by missiles and drones. Twisted, burnt and blackened by fire the aftermath of multiple drone and missile strikes across 19 targets, hitting the very heart of saudi arabias 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 its 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 theyre confident they can restore production by the end of september. What they cant say with any confidence is they can prevent such an attack happening again. Repair teams are still working around the clock. This isntjust about patching up the holes, its 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 well 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. Thats perhaps why one week on, it is still no no hurry to retaliate. One of the consequences of Donald Trumps hardline policy on migrants has been to leave thousands of people stranded on the mexican side of the us border. Thats raised concerns about their safety but american Officials Say the wellbeing of migrants is mexicos responsibility. The bbcs Stephanie Hegarty reports from the town of matamoros.

They were detained for seven days. Here on the mexican side in matamoros, hundreds of people are camping out. There is nothing here, no shower facilities, no toilets. The reason why the people we spoke to say they are staying here is because they are afraid to go further into mexico. This is one of the most dangerous states in the country. Gangs rule the towns along the border, fuelled bya the towns along the border, fuelled by a roaring drug trade for the us. All of these shootings happened in the state within a week of our visit to the border. And the gangs treat migrants asa to the border. And the gangs treat migrants as a cash cow. This woman came from honduras with her husband and her three year old son. They were kidnapped as soon as they arrived at the border.

You might remember us telling you about a planned raid on area 51. More than three Million People signed up online pledging to storm the top secret airbase where the Us Government is supposed to be hiding extra terrestrials. So how did it all pan out . The bbcs tim allman will tell us. As invasions go, alien or otherwise, this was a little underwhelming. For those who bothered to turn up, the hunt for little green man is always worthwhile. Dozens of people standing outside of a government base. Why would you want to miss that, it is a once in a lifetime experience will stop it is like halloween but we are just annoying people. We clicked that we would be going just for the fun of it but as it got more popular we decided hey, why not, go down and make a fun trip of it so we go down, were going camping and going to check out the base as much as we can from here. Miles of barbed wire circle the facility in nevada. What actually happens here is hush hush but it is believed to be a test site for experimental aircraft. Others, though, remain convinced the truth is still out there. If you witnessed it, you will believe. There is stuff out there that is incredible, that you wouldnt believe unless you saw it for yourself. Im a believer that there are aliens. One person was briefly detained for urinating near the main gate but the whole event was reasonably good natu red. The main gate but the whole event was reasonably good natured. Then invasion over, much like et, they all went home. Tim allman, bbc news. What a night out you can reach me on twitter im bbcnuala. Hello. Friday brought a lot of sunshine to a lot of places across the British Isles and i dont think were 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 of us just at the moment. 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 about 15, i6, 17 but come inland, 20 plus is widely available. Through saturday night and on into sunday, the first signs of the change in that the High Pressure drifts further away and in comes the front 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, some of it 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 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 that 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. Its all going to be quite mobile so it wont rain persistently anywhere for the whole day but while that rain is around, you will notice it, this is not showers, thisis belts of rain moving in from the atlantic. And 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 and at times, some really quite strong winds. Quite a change on the way.
