Win over argentina. Good evening. Donald trumps political opponents have intensified efforts to impeach the president. Three congressional committees have demanded legal documents relating to a telephone call by mr trump in which he asked ukraine to investigate his president ial rival, joe biden. From washington, Chris Buckler reports. What was a request has become a demand. Democrats are piling the pressure on President Trump by issuing a subpoena for a series of documents. They want a full, rather than a rough, transcript of thejuly phone call in which he asked the ukrainian leader, Volodymyr Zelensky, to investigate his political rival and potential president ial candidate, joe biden. And amid all the talk of impeachment, mr trump continues to make unfounded allegations about mr biden, who hopes to challenge him in next years president ial election. Youre pointing out when hes flatlining, where there is no evidence, none, not a scintilla, not one tiny piece. The American People know me, and they know him. Even the people who support him know this man lacks character. Even people who support him know he lies constantly. In a letter, the chairmen of three congressional committees accused mr trump of choosing a path of defiance, obstruction and cover up. In response, the white house accused the democrats of setting up a Kangaroo Court that would only waste time and taxpayers dollars, and President Trumps press secretary insisted that all their inquiries would ultimately show that the president had done nothing wrong. Chris buckler, bbc news, washington. Iran has released a british australian woman and her boyfriend, whod been detained for 3 months on spying charges. Jolie king and her australian partner, mark firkin, had been accused of using a drone to take pictures of military sites. Separately, an iranian student has reportedly been freed in australia, but its unclear if the 2 developments are linked. Australias foreign minister says tehran has dropped all charges against the couple. The yet very long term negotiations, she has been you know contained for some considerable time and has a the iranian leader system and has been convicted and sentenced so as i said in my remarks in each of these cases are unique and different. So we are continuing our discussions with the iranian government. We do not accept the charges upon which she was convicted in the weight seek to have her returned to australia. The mother of a teenager who died in a crash involving the wife of a us diplomat says the government must put pressure on her to return to the uk. Harry dunn, who was 19 and from charlton in northamptonshire, died after the accident near raf croughton in august. The diplomats wife has claimed immunity and travelled to the us. The boys mother, charlotte charles, says she will meet the foreign secretary, dominic raab, in the coming days. Police said they wanted to interview an American Woman in her 40s. As many as eight people have been seriously injured after a double decker bus overturned in devon. The vehicle crashed on the a385 between totnes and paignton at about 11 this morning. Emergency Services Declared a major incident. Police have closed the road in both directions and asked people to avoid the area. Catherine serjeants friend was trapped on the bus she rushed to the scene when she heard about what happened. They are obviously dealing with the most injured people first, my friend was trapped on the bus for 45 minutes but thankfully she was not injured and they had to cut holes in the roof of the bus to get people out and obviously they could not move people who are badly injured so they were trying to get those people out first. The government has indicated it could clarify its new brexit offer after the eu called for fundamental changes. Talks will resume on monday after the eu said the uks proposed alternative to the irish backstop could not be the basis for a legally binding treaty. Borisjohnson has insisted the only options are a new deal or no deal. Our Political CorrespondentSusana Mendonca explained how the deal presented by borisjohnson to the eu fell short of what leaders were looking for. The sense that we got from the European Union is that what is on the table at the moment is not what they are after and borisjohnson has basically said he will want a situation where he had Northern Ireland staying within the Single Market for goods but leaving the whole of the uk and leaving the eu customs union. One of the key challenges and debates around all of this and the reason for the backstop which is this insurance policy to prevent a hard border is about trying to keep an open border between Northern Ireland and the republic of ireland. This plan by borisjohnson, the republic of ireland. This plan by Boris Johnson, the government republic of ireland. This plan by borisjohnson, the government say that you will be able to do border checks and factories and away from the border. But the European Union does not seem particularly convinced of that. So far for the eu, does not seem particularly convinced of that. So farfor the eu, leo varadkar, b irish p. M. Saying ifall short and donald tusk saying he has not convinced and the negotiations with the e diplomats say that that fundamental changes have not happened. We understand that they will clarify changes and by Boris Johnson is also going to be heading to meet eu readers in the coming weeks so certainly there will be an intent to get something that can be put to permanent but essentially if he doesnt manage to get something to print tape proudman, potentially, brexit may not happen or it could leave deal or no deal. John mcdonnell is in colchester today and is the shadow chancellor. Is talking about the need to raise Living Standards and he did not think a deal that placed johnson put forward was actually a real deal. Much like an election stand and it looks like they put forward the proposal that the eu would not acce pt proposal that the eu would not accept and on that basis Boris Johnson will portray himself as some sort of victim either from the eu or parliament and that will be the basis of his election campaign. What we want as a Prime Minister who looks after the long term and our country and make sure we will rule iio country and make sure we will rule no deal at the table completely and goes into negotiations and secures a sensible deal and puts it back to the people with the option to remain. What we want is to bring the country back to my back together again and the best way to do that is that people speak. Trying to get some clarity here, the 19th of october, if he has no deal what happens . Is it saying he will do one thing and he is saying something else. There are in terms of a law brought and, it means on the 19th of october he needs to havee brought and, it means on the 19th of october he needs to have a deal passed through parliament, the parliament agreed to a deal and said ber has to agree with the deal and moment has to agree it is ideally they are willing to accept. If that does not happen he has to write to the European Union to ask for an extension for us to remain in the European Union. Boris johnson extension for us to remain in the European Union. Borisjohnson has said that he will obey the law, that is what the law says and certainly there is a court case at the moment and scotland which is looking at this very issue and in paper is submitted to that court. He says he will obey the law but he is also saying that he will leave the European Union with or without the deal and that is what all the questions are being raised about what does that mean and does that mean that he is looking for some kind of loophole . At least five people have been killed in clashes between protesters and police in the iraqi capital, baghdad. The Iraqi Parliament says more than 90 people have been killed, and almost 4,000 others have been injured in unrest across the country this week. The protests began over unemployment, Poor Public Services and corruption , but demonstrators are now also demanding that the government resign. Prosecutors in paris say the man who worked at Police Headquarters and killed 4 colleagues may have believed in an extreme vision of islam. Reporters were told that the 45 year old computer expert exchanged 33 texts with his wife that were religious in character ahead of the attack. He was shot dead by police after carrying out the stabbings. Much of hong kong is shut down after violent demonstrations led to the suspension of the citys public transport network, many shopping centres, banks and businesses have been unable to open. Thousands of people have taken to the streets today to protest against a newly imposed ban on wearing face masks. Hong kongs leader, carrie lam is warning that she can no longer tolerate rioters destroying the territory. Translation the extreme actions of rioters created a very dark night for hong kong and made Hong Kong Society semi paralysed. Everyone is very worried and concerned or even scared. The government will suppress violence with the greatest determination. I appeal to everyone to support the government in suppressing violence in accordance to the law, condemn violence together, and cut ties with rioters with a firm will. At a News Conference in kuala lumpur, the United Nations high commissionerfor human rights, michelle bachelet, said the ban on Face Coverings should not be used as a way to target or disrupt people taking part in peaceful demonstrations. Bans on Face Covering during assemblies are, in some circumstances, used to target particular groups and improperly curtail their freedom of expression or peaceful assembly. So freedom of peaceful assembly, when we are talking about peaceful assembly, should be enjoyed without restriction to the greatest extent possible. But on the other hand, we cannot accept people who use masks to promote violence. That is also not acceptable. Earlier i spoke to the bbcs asia pacific editor, celia hatton, who gave me her assessment of events in the territory in the past 24 hours. Last night, we saw some of the most violent uprisings to mark the past four months, really. This is really in response to the chief executives announcement that face masks would no longer be allowed, even in peaceful protest. So, we saw relative chaos last night in hong kong. Today, its eerily quiet across the territory. Now, we have seen small protests pop up many ordinary people, moderates, unarmed protesters, turning out to mark their displeasure against the face mask ban. We are also hearing of reports of violence against businesses that are perceived to be owned by mainland Chinese People and so thats another development. But, yes, i mean, we are into month four of these protests and, yes, its the weekend again, this is supposed to be a Holiday Weekend in hong kong, but really this is a city that once prided itself on its efficiency, now the underground system has been shut down for the first time really in memory and you know this is a place that really has been changed. Now you have mentioned a national holiday, everybody was very worried looking to october ist, just explain that significance us to. Well october ist was a really big day in the calendar in mainland china. Thats when the communist party marked 70 years of the peoples republic of china. Now, moving towards that important date, october ist, beijing was preparing for its largest ever military parade, the chinese president gave a big speech. We didnt know watching hong kong, we could see pressure building towards that date, we knew a lot of people were planning protests in hong kong to mark their grief, as many put it, of imposition of chinese rule and it wasnt clear whether the temperature was going to continue to go up after that, tensions were going to continue to rise, or whether things would begin to calm down. But now that we have had this announcement of a face mask ban, we can see that things really havent improved in hong kong. Wheres it all leading to, because we heard carrie lam say she is no longer going to tolerate this, shes still at the helm, beijing is displaying very unusual, it is uncharacteristic calm, restrainr on hong kong. Explain why. I think, if youre expecting to see military tanks, Chinese Military tanks rolling down the streets of hong kong, you know the famous tank man image re enacted on the streets of hong kong, i dont think were going to see that any time soon, if at all. But i dont think beijing is being calm, i think beijing is enacting a lot of measures behind the scenes to really put pressure on the hong kong authorities, the hong kong police, hong kong businesses, to start bringing an end to these protests and i think thats really what we are going to see as time goes on. We have seen the hong kong authorities enact, use an emergency law that hasnt been used since 1967, to put the face mask ban in place, were seeing heightened police tactics. So, even though we havent seen maybe the measures that we thought beijing might bring into place when these protests first started, i do think that beijing is doing a lot of things to try too bring an end to this. Let us go to hong kong. Bonnie leung is a pro democracy campaigner who has organised some of the recent protests. Shejoins me from hong kong via webcam. Thank you for speaking to us here on bbc news. First off, carrie ran a saying that she will no longer tolerate what is going on in the tory tory and we saw the ban on facemasks and how worried are you. Tory tory and we saw the ban on facemasks and how worried are youlj am facemasks and how worried are you. am extremely worried because i am worried about the front line protesters at safety. Carrie lam is once again doing and at her back move and a strategy of bypassing our legislature to impose yet another evil law. By doing so, i believe that she is actually creating some sort of systematic mum to public anger so sort of systematic mum to public anger so it exploded. It is totally counterproductive and she said that the reason that imposing the anti masking law is about resuming public law and order and protecting front line Police Officer safety, that you see is totally counterproductive. The public is more angry and more people are wearing masks, wearing facemasks to protest in the streets. People are forced to be even more radical and protests of the latest evil law so it is totally counterproductive and it is totally counterproductive and it is totally counterproductive and it is not serving the purpose at all. I am trying to get the idea of what people are fighting for because the fight has changed, has in it from the extradition bill. To give you a raise in the uk an idea of why this is so important to you and the protesters, how has life changed since the handover . After the handover, what we used to have is rule of law and freedom. Despite we did not have true democracy. But now because we do not have true democracy the government is totally not being accountable to the people and that is trying rule of law the rules that we have always treasured so rules that we have always treasured so hong kong people are now to conclude freely to seek for protection. Now we see the Police Officer is breaking the law so blata ntly officer is breaking the law so blatantly caught on camera without any legal consequences at all and they are protected by the Police Commissioner and protected by the Hong Kong Government and protected by the government. We see absolute power clap absolutely. So people cannot leave the movement, we have to ta ke cannot leave the movement, we have to take care of that. Talking about power, outside of hong kong and china, what team makeup statements released from foreign leaders on events taking place in hong kong, is that enough for you . We are grateful because hong kong Needs International support and it cannot do it alone but we need foreign leaders to do more, especially the uk because you were one of the signer of the british joint declaration so we hope you can actually declare the. And because asi actually declare the. And because as i said they think they can get away with it from the Police Officers, to beijing governments, they think they can get away with it. That is unfortunately seem to have lost bonnie long speaking to us from hong kong. Apologies for that. We will try to get to her later in the evening here on bbc news. Living on, she thought it was the end of her career but she is making a little bit of history, the first performance by a transgender is seeing her on the opera. Shes appearing in orpheus in the underworld at the English National opera. However, on stage because of her deep baritone voice she continues to play male roles. Our arts correspondent, David Sillito reports. Hi. My name is lucia lucas and i am a professional opera singer. She sings opera. I am not trying to be a pioneer.

Ive done some research on that and for better or worse it doesnt change. And so for th
