Remembering the largest Airborne Assault in history, a 97 year old veteran of the battle of arnhem takes to the skies to mark its anniversary. The Us Democratic president ial contender and frontrunner, joe biden, has accused donald trump of an overwhelming abuse of power. It follows reports he tried to pressure ukraine into opening a corruption investigation against mr biden and his son. Leading democrats say if true it could be grounds for impeachment. President trump says its another witch hunt. Our north america correspondent david willis reports. I know trump deserves to be investigated. He is violating a very basic norm of a president. You should be asking him the question, why is he on the phone with a foreign leader, trying to intimidate a foreign leader . If thats what happened, thats what appears happened. You should be looking at trump. Trump is doing this because he knows ill beat him like a drum and is using the abuse of power and every element of the presidency to try to do something to smear me. What this row centres on is a telephone conversation which clearly took place during the summer between President Trump and the new leader of the ukraine, and its been reported that on a number of occasions, possibly as many as eight occasions during the course of the telephone conversation, mr trump urged Volodymyr Zelensky to investigate the son ofjoe biden, who worked for a ukrainian gas company. The former Vice President and the leading contenderfor the former Vice President and the leading contender for the the former Vice President and the leading contenderfor the nomination of president going into the election next year. This conversation is thought to have formed the basis of a whistleblower complaint which went to the intelligence Inspector General a few weeks ago but was suppressed from being released to congress. It is thought that was following pressure from the white house. Now, today on twitter, mr trump dismissed the controversy as fake news, calling it a perfectly fine and routine conversation with the ukrainian leader in which nothing was said that was in any way wrong. But there are reports that mr trump urged the leader of ukraine to meet with his personal lawyer, rudy giuliani, to look into suggestions regarding the activities ofjoe bidens son, hunter biden, who worked for a ukrainian gas company. There are suggestions joe biden, as Vice President of the united states, threatens to withhold International Aid money to ukraine unless a prosecutor who was investigating the gas company that his son worked for was sacked. That really is the very detailed, torturous background to all of this. It is a complicated subject. But it has got President Trump and his democratic rival, joe biden, at loggerheads, both in social media and in interviews with the press. We often see this in politics, dont we, and in us politics especially, when donald trump is involved, this sort of he said, she said merry go round. Do you think there is any chance the house of representatives will do whatjoe biden asks and investigate this . Interestingly, they have subpoenaed the acting National Security adviser to give evidence before them next week. The head of the house intelligence committee, a man called adam schiff, has warned that if this complaint in its entirety is not presented to congress, then he may pursue legal action to enforce that situation. So that backs the white house into something on a corner. President trump of course argues, as i have mentioned, that this is all fake news and that the democrats are spoiling for something on him, following what he sees as the failure to basically nail him with the mueller investigation, the special counsel inquiry into russian meddling in the last election, run by robert muller. Tensions in the gulf are rising once more, in the aftermath of the bombing of a saudi oilfacility. The Saudi Foreign minister has accused iran of being responsible for the attack saying his country will respond with necessary measures. And the united states, an ally of riyadh, has announced it will send troops there. The bbcs Frank Gardner is in saudi arabia and sent this report. Punctured, bombed, and blasted, the graphic aftermath of last weekends missile and drone attack on saudi oilfacilities. The pinpoint attack, quickly blamed by the us on iran, temporarily knocked out half saudi arabias Oil Processing capacity. Iran denies responsibility, but today, this revolutionary guards commander issued a fiery warning against any possible retaliation. Translation a limited aggression will not remain limited. We will punish you. We will follow you. We have shown we will not rest until the aggressor is destroyed. The us has held off military action, instead, slapping sanctions on Irans Central Bank and its sovereign wealth fund. Its also sending additional troops to defend saudi arabia. At a press Conference Today in the saudi capital, the minister of state welcomed this move. In addition to the us, weve also had very Strong Military cooperations from a number of other allies, in particular the united kingdom, and i think that the challenges we are facing now call for enhancing Security Cooperation between the kingdom of saudi arabia and its allies and partners. The saudi government has welcomed the deployment of additional us troops to bolster its air defences. Now is the time, said the minister, for his country to work more closely with the us and britain. Iran, he said, was to blame for all the recent missile attacks on his country. Only days ago, President Trump said the us was locked and loaded, but the saudis called for restraint, and washingtons measures appeared defensive. But with tensions high, it may not take much to change the president s mind. Lets get some of the days other news. The Islamic State group says that it carried out a bomb attack on a bus near the iraqi city of kerbala that killed 12 people. Iraqi police say an explosive device was planted on the bus and detonated at the northern entrance to the city, a major site of pilgrimage for shia muslims. The interior ministry in kazakhstan says 57 people have been arrested in the countrys two main cities after attending opposition protests against chinese influence in the country. Beijing invests heavily in kazakhstans Energy Sector but is accused of under paying its kazakh staff. A 5. 6 magnitude earthquake has struck albania close to the capital tirana. Reports say 50 people are being treated for injuries at the main hospital. The Defence Ministry said it was the most powerful earthquake in 30 years. A sit in is being held in hong kong to mark two months since an attack by pro beijing vigilantes on protestors and commuters left 45 people in hospital. Earlier police fired tear gas on Anti Government protestors when a rally in the district of tuen mun turned violent. Thousands marched from tuen mun park to the government offices there in a demonstration that had been approved by police. The march was initially called in response to pro beijing protestors tearing down colourful Anti Government posters, known as lennon walls afterjohn lennon. Its the 16th consecutive weekend of protests in hong kong. This is the moment that protestors threw molotov cocktails at riot police. You can see the police fired tear gas in attempt to disperse them. Here are the riot police arresting protestors. The police have previously been criticised for their heavy handed approach. And heres a barricade that was set on fire by protestors earlier. Our correspondent Stephen Mcdonell is in hong kong. Todays rally was cleared that is, they had official permission to march. And yet, again, it s turned into one of these street battles. This week, a Senior Police officer told us that they are stretched to the absolute limit. They say theyre handling this crisis, but if there was to be a greater escalation the only way they could deal with that would be to eat into other areas of their police work. As the Police Detained protesters, theres a lot of attention from the local media. This is a speciality case given the Amnesty International report that was released a few days ago, accusing the police of excessive force. Now this is something the officers here deny. But, given that, when they apprehend people, the media are on them. After being cleared out of other areas, protesters have come here to yuen long to mark two months since triad connected gangs ambushed activists and, using home made weapons, bashed them in the train station. Now theyve accused some Police Officers of colluding with those gangs. Thereve also accused some pro beijing the politicians are being linked to the underworld. This is why they want an independent enquiry, which is one of their key demands. And you can hear them calling out now five demands, not one less. Talks will be held in a few hours in a last ditch effort to try to save thomas cook, the uk Tour Operator and one of the wells oldest holiday companies. A previous rescue plan failed. Lenders want the company to find an extra 250 million to secure its future and its approach that it has approached the British Government for a bailout. Around 600,000 holidaymakers government for a bailout. Around 600 , 000 holidaymakers around government for a bailout. Around 600,000 holidaymakers around the world could be stranded if the company collapses. With me is the bbcs simonjones. First of all, can you give us an idea of where these talks are out at the moment . We are expecting talks to ta ke the moment . We are expecting talks to take place in the morning in the city, these are being described as potentially the most important talks that have taken place in the 178 year history of the firm. Now, thomas cook is one of the best known travel firms in the industry. It has around 19 million customers each year. Around 19 million customers each yea r. Lots of around 19 million customers each year. Lots of those are british customers, but also lots of people from germany and scandinavian countries. So we are expecting in the morning, details have not been confirmed by the company itself, but we are expecting some of those with investments in the firm to meet to try to discuss a way forward, because thomas cook is being told it needs to hundred million, around 250 million, just to keep going. Why hasnt got into this financial problem . Well, why hasnt got into this financial problem . Well, partly why hasnt got into this financial problem . Well, partly we talk about a lot in the uk, brexit, so customers not booking holidays because they dont know potentially what is going to happen after the end of october when the uk is scheduled to leave the eu. Also partly the heatwave we saw across europe last year when lots of people simply decided it was lovely atonement they didnt need to go abroad, and also partly being blamed on instability in certain areas like turkey, which is traditionally a popular holiday destination for the firm. So people who are currently travelling and Public Holidays with thomas cook, what is the advice for them . At the moment it is thought there around 600,000 customers who are currently already on thomas cook holidays. They are being told to carry on. If we look at it for british holidaymakers, we think there are around 160,000 british holidaymakers. Now, if they booked a package holiday it is protected by something called a. Atol. That means if the firmware to go under, they would be a scheme where people would be brought back to the uk. So they would be to continue on their authorities holidays, and the Civil Aviation authority under the British Government would delay on flights, essentially with different firms, to get them back. 0ther nationalities have a similar scheme. Lots of german holidaymakers potentially affected by this. They will be a similar scheme operating in germany, so the German Government and of the governments across europe will be looking at similar schemes to enable people to fly back home so they are not left stranded. What about people who have booked with thomas cook but have not travelled yet . It is a very worrying time. We have heard from people who for example have booked weddings abroad for later in the year, people who have booked tickets for the whole of theirfamilies. Very have booked tickets for the whole of their families. Very concerning for them. What they are being told is that if the firm does go under, once again, if it is a package holiday, they will get a refund. But obviously they will have to try to make alternative arrangements if they want to carry on going on the holidays. There is also the issue of people who have not booked a package holiday but have simply booked flights. Now, they are not protected by this atol scheme, or similar schemes in european countries. But people who have booked a flight only are being told they could try to claim that, either from their debit 01 claim that, either from their debit or credit card, or via their holiday insurance, so it is hoped they would not be out of pocket. 0nce insurance, so it is hoped they would not be out of pocket. Once again, it is that uncertainty of having your holiday planned and not really knowing how are going to get there if your first plans are cancelled. So should things go south for thomas cook and the company fails, what is the governments plant in terms of the governments plant in terms of the British Government, to rescue british people . This would be a huge operation, as i said. Around 160,000 british holidaymakers abroad with thomas cook. Now, there has been a figure put on it that it could cost around £600 million, 750 million, to repatriate all the uk citizens, to repatriate all the uk citizens, to bring them back to the uk. It would be the biggest repatriation operation since world war ii, to give you an idea of the scale of it. We would see similar things happening in other countries as well. So this would be a big deal. But plans are being drawn up behind the scenes, because it has been thought by Industry Analysts that this is a very real possibility, but things will go wrong. I spoke to one travel expert and he put it at about 5050, travel expert and he put it at about 50 50, whether or not the company would survive. It all depends on this crucial meeting in the morning with creditors about whether they are prepared to put in more money to the firm to help try to save it. 0therwise the firm to help try to save it. Otherwise we could see one of the biggest names going under. Everyone is going to be keeping an eye on what happens next. Simonjones, thank you very much. Stay with us on bbc news. Still to come what happened when a peaceful climate march in paris was infiltrated by hundreds of anarchists. Ben johnson, the fastest man on earth is flying home to canada in disgrace. All the athletes should be clean going into the games. Im 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. 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. 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 democratic president ial frontrunner, joe biden, has accused donald trump of an overwhelming abuse of power over reports that he tried to put pressure on ukraine to launch an investigation against him. Theres been a day of protests and sporadic clashes in paris, as a Climate Change demonstration was infiltrated by activists associated with anarchist groups and by yellow vest supporters. French Police Responded with tear gas as the radical groups broke shop windows, set up barricades and set fire to bins. More than a hundred people were arrested. The bbcs tim allman reports. From the start there was a big police presence. For what was meant to bea police presence. For what was meant to be a peaceful demonstration. And to be a peaceful demonstration. And to begin with it was. With an almost carnival like atmosphere. Everyone at united in their desire to save the environment. Translation we cant keep on going like this. This is an emergency. We have to take measures in terms of the budget, in terms of the general organisation of the state does make spending, where the environment is to ta ke spending, where the environment is to take priority over everything else. But as the day wore on, the situation became more violent. Chanting. Anarchist groups accused of exploiting the climate notice to make trouble. Soon police were firing tear gas as demonstrators damage shop windows and started fires. One officer appeared to spray the lens of a camera crew as they we re the lens of a camera crew as they were trying to fill an arrest. Organisers eventually told the protesters to stay safe and go home film. Thousands of miles away, on the other side of the atlantic, the action against Climate Change took a different form. A meeting at the united nations, among those invited, greta thunberg, the swedish schoolgirl who has become a symbol of environmental activism. Millions of environmental activism. Millions of people across the globe marched and demanded real climate action, especially young people. We showed that we are united and that we young people are unstoppable. The sentiment shared all around the world. Here a demonstration in indonesia. Climate change is a global problem and it will need a global problem and it will need a global solution. Tim allman, bbc news. The bbcs nada tawfiq has been meeting activists at the un summit that tim mentioned in his report and she gave us this update. The Pacific Island countries are the first was to be feeling the impacts of Climate Change and we needed to bring it out there to show the world of the realities of Climate Change is, how people have started suffering. And it is notjust words and solutions that you can sit and talk about, it is something that needs urgent attention and an urgent implementation declare these issues. What are some of the effects you are already seeing mvg . The first one is the sea level rising. People have already experienced the impacts of that. Small island countries have started experiencing king tide s the rise of the sea levels whereby their homes are being affected did and in fiji already we have three locations that relocations that have taken place. The government has identified about a0 villages that may need to be relocated in the next 510 may need to be relocated in the next 5 10 years to come. May need to be relocated in the next 510 years to come. Very quickly, what responsibility, specifically, the do you think developed countries, the biggest polluters, have to small islands like yours . guess for the bigger countries they are the ones who should be leading by example. So as i said, walk the talk. If you are talking about the Climate Crisis and in cementing it, finding a solution for it, the bigger leaders needs to be the ones should be stepping up first, not just thinking about their economies, but thinking about their people in the country as a whole. Lets get some of the days other news. Chicago police have arrested a 22 year old man after a car was driven into a Shopping Mall in the suburb of schaumberg in the dramatic video posted online shortly after the incident shoppers can be seen fleeing as the car ploughs through the shopping centre. Three people were taken to the hospital for non life threatening injuries. Why the car crashed into the mall in the first place still has not been revealed. This is the moment a meteor lit up the sky in australia. Seen over the states of tasmania and victoria, the meteor produced a vivid light but experts say it may have been as small as a tennis ball. It was the largest airborne operation of the second world war. The battle of arnhem was the failed bid to recapture a key bridge held by the germans in an attempt to bring an early end to the war. More than 1,500 British Service men were killed. 75 years on, theyve been remembering operation Market Garden and those who lost their lives. Jonathan beale has more. Sandy kaufman was preparing to jump into battle 75 years ago. Now aged 97 he is one of the last of the surviving arnhem veterans leaping into the skies again. In 19aa, he was taken prisoner soon after he landed, but today he was being welcomed by applause, rather than enemy fire. Does it bring back memories . Not really, no. Laughter. British and nato troops joined in the drop to remember the bold plan to capture a series of bridges behind german lines. Still, just a fraction of the allied troops that took part in what was the largest Airborne Assault in history. Arnhem is the story of heroic failure. The british never managed to take the bridge. 1,500 were killed and thousands ta ken prisoner. This will probably be one of the last big events witnessed by the ever dwindling band of veterans who landed here 75 years ago. But those they came to liberate say they will never forget the sacrifices they made. 75 years later and we are here with our children, so it is important that they know, where we remember the war and everyone who fought for us, for ourfreedom. I think it is very important. It should be remembered for many, many years. That is why we are here. It wasnt just locals, but also relatives and royalty who came to honour their bravery. Along with a few surviving veterans likejothefferies, who still comes to remember the friends he lost. So many men wiped out. I couldnt believe it. There may be fewer of them with each passing year, but the dutch who they came to liberate, say theyll never be forgotten. Jonathan beale, bbc news, arnhem. Mexicos popocatepetl volcano has been caught on camera erupting in the early hours of saturday the dramatic footage shows a plume of ash and gas rising over a thousand metres into the sky above the snow capped crater. Activity has been ramping up in recent months. The volcano is located 80 kilometres south east of the capital, mexico city. You can reach me on twitter im regedahmadbbc. Hello there. While saturday brought us another warm, dry september day across much of the uk, things are now changing from sunday and through the course of this coming week its a more unsettled picture. Rain or showers at times through the day on sunday and things will start to feel a little bit cooler than they have done recently, too. And the reason for that is that weve got low pressure out towards the north west of the uk. And thats going to be driving in some weather fronts through the day. And weve got further low pressure systems waiting out in the wings for later on in the week. So we start off sunday morning with some heavy showers, particularly across south west england, the midlands, wales, northern ireland, too. Some thunderstorms likely with some of those showers. They drift their way northwards and eastwards across the uk, followed by another band of rain. Some drier and brighter whether working in from the south west in the day. So a bit of sunshine around. And i think northern and eastern scotland probably holding onto the sunshine for a good part of the day. 18 23 degrees, so cooler than it has been, but still reasonably warm for some eastern areas where you do see the sunshine at times. Now that showery rain should start to clear away towards the north and the north east as we move through sunday night and into the early hours of monday morning. There could be some mist and fog patches around first thing monday. And it will be a slightly resonate sunday night compared to this current night. But still frost free around 11 13 degrees. Now heading on into monday, and this next area of low pressure moving in, thats associated with the remnants of ex hurricane humberto, so it will bring some wet and some windy weather eventually to the uk, but nothing unseasonable here. In fact, much of monday looks dry and fine with some sunshine, still a bit cloudy and damp across the north of scotland. Late in the day that is where we see the wind speaking up in the rain arriving across south western england and wales and northern ireland, too. Central and Eastern England should keep the sunshine through much of monday, 20 degrees also here. Typically the high teens for most of us. Certainly cooler than it has been recently. More blue on them up for tuesday. More rain. Some of it could be quite and thundery, too. Also still quite breezy, especially towards the south. But some sunny spells in between the showers, so not a washout on tuesday. But its certainly feeling cooler than it has done recently, with most of us seeing temperatures at 17 18 degrees also on tuesday. And then with low pressure not far away as we look through the rest of the week, plenty of showers symbols on the outlook chart for the Capital Cities of the next five days or so. Showers around, particularly across parts of scotland, and northern ireland, too. Some sunnier spells for the south and east, but an unsettled story for much of the week ahead. Bye bye. This is bbc news, the headlines the democratic president ial frontrunner, joe biden, has accused donald trump of an overwhelming abuse of power. If follows reports that the president tried to pressure ukraine to investigate mr biden and his son. Mr trump insisted his talks with foreign leaders were always appropriate. Saudi arabia has vowed to take appropriate action once the investigation into last weeks attack on its Oil Installations is complete. The Saudi Foreign minister has insisted iranian weapons were used, and has rejected the claim by Houthi Rebels in yemen that they carried out the attack. And commemorations have been held to mark the 75th anniversary of the largest Airborne Assault in history. The battle or arnhem in world war ii saw around 35,000 allied Soldiers Land behind enemy lines
