By the territorys chief executive, carrie lam, to use Emergency Powers to ban the face coverings frequently worn by pro democracy demonstrators. Gareth barlow has the latest. Hong kongers resist, that was the call as protesters formed human chains, as they defied a ban on facemasks while demonstrating. Everyone knows carrie lam is messing up hong kong. This is why she is pushing through with the emergency law. We all expect the next step to be imposing a curfew. This is a tool, a way to suppress hong kong people. Carrie lam has not learnt from this and has not done anything to appease us. She is just constantly suppressing us. Throughout the city, shops and transport hubs remain closed after a spike in violence. In a televised address, hong kongs chief executive carrie lam pledged to quash the violence. Fellow citizens, hong kong had a very dark night last night because of the extreme acts of the rioters. Today, the city is semi paralysed. Everyone is worried or even afraid. The government will act with the utmost determination to curb violence. Months of protests have paralysed hong kong hand have proven a stern test of the laws that provide greater freedoms compared to mainland china. Business groups are pressuring the government to end the protests but the authorities new tactics may trigger more violence rather than stop it. Gareth barlow, bbc news. Us secretary of state mike pompeo has dismissed questions about president trumps attempts to push ukraine and china to investigate democratic rival joe biden as a silly gotcha game. Democrats leading the impeachment inquiry into the us president have issued a legal order demanding the white house hand over more documents on its dealings with ukraine. Chris buckler reports from washington. No matter where americas commander in chief goes there is no escape from the talk of impeachment or the many questions about his request for a Foreign Government to investigate one of his political rivals. Requests for documents from the white house have become demands with a subpoena issued by the democrats alongside a strongly worded letter that accuses the president of choosing a path of defiance, obstruction and cover up. Among the many records they want is a full, rather than a rough transcript, showing exactly what mr trump said to the ukrainian president in a phone call during the summer. That is when he controversially tried to pressure for volodymyr zelensky, into launching an inquiry into the potential president ial candidate joe biden and his son, hunter, who had business dealings in the country. On a visit to greece, the us secretary of state could not hide his frustration at this latest attempt by congress to put pressure on the president. This is what is wrong when the world doesnt focus on the things that are right, the things that matter, the things that impact real peoples lives and instead you get caught up in some silly gotcha game. But democrats have still to decide on whether to hold a formal vote to impeach the president. Some people say why are you doing this, he is not worth it. To divide the country this way. I said, well, he may not be but our constitution is worth it, our democracy is worth it. The battle lines are being drawn in washington and congress is preparing for yet another bitter fight with this white house. Chris butler, bbc news, washington. Lets look at some other stories in brief. A north korean negotiator says Nuclear Talks with the United States have broken down, blaming washington. The Us State Department says north koreas comments dont reflect the content or spirit of the talks, which lasted for more than eight hours in sweden. An attacker, who killed four people at the Police Headquarters in paris, adhered to a radical version of islam. Anti terrorist prosecutors said Michael Harpon had converted to islam 10 years ago and recently showed signs of radicalisation. At least four men, all believed to be homeless, have been bludgeoned to death while they were asleep in new york. A fifth person is critically ill. A suspect is in custody. A british australian woman and her australian boyfriend say theyre relieved to be home after more than three months in an iranianjail. Its reported thatjolie king and mark firkin were freed as part of an exchange, as James Landale reports. The views here are just epic. Jolie king and mark firkin were travelling the world, recounting their adventures to thousands of followers on social media. It has honestlyjust blown us away. But three months ago, the british australian woman and her australian boyfriend were arrested in iran, allegedly for flying their drone without a permit near military installations. Yet more foreigners detained in tehrans jails. Yeah, so weve been driving for a couple of kilometres now. But after what the Australian Authorities describe as sensitive negotiations, the couple from perth have been released and have returned home. Forjolie and for mark, the ordeal they have been through is now over. They are being united with their loved ones, which is a source of great relief and joy to everyone. I can tell you that theyre in good health and in good spirits. Later it emerged that australia had released an iranian student, Reza Dehbashi kivi, who had been arrested in 2018 for allegedly sending us made military equipment to iran. This prompted speculation both countries had negotiated a Prisoner Exchange something the Australian Authorities refused to comment on. They said they were still trying to secure the release of another british australian an academic called kylie moore gilbert, who has been held in iran for almost a year, charged with spying. Todays release will prompt questions about why the British Government has yet to secure the freedom of Nazanin Zaghari ratcliffe, the british iranian mother detained in iran, despite denying accusations of spying. The Foreign Office wouldnt comment tonight but the cases are different. Iran has a much more hostile relationship with britain than australia. Mrs Zaghari Ratcliffe is considered by tehran to be iranian and its thought she has greater diplomatic value to iran in its confrontation with the west. And unless that changes, mrs Zaghari Ratcliffe looks set to remain injail and now without any visits from her five year old daughter, gabriella, who she is sending home to start school in the uk.

Borisjohnson has urged the eu to show its willing to compromise with the uk on a brexit deal. Writing in two sunday newspapers, the Prime Minister appeals to the eu to begin serious negotiations. But europes chief brexit negotiator, michel barnier, has said he couldnt advance talks based on the current wishes of the remaining 27 eu leaders. At least five people have been killed in the latest clashes between Anti Government protesters and the Security Forces in iraq. Hundreds of demonstrators took to the streets of the capital, baghdad, despite a heavy security presence and an appeal for calm from political and religious leaders. Our middle east editor sebastian usher reports. Despite heavy security, young iraqi protesters have come out onto the streets for the fifth night in a row. Once again, the Police Responded with force, firing tear gas into the crowd in an effort to keep them away from the main squares. Hundreds have been injured in the days of protest, raising the prospect of a wider and more dangerous confrontation. The demonstrations are fuelled by anger and frustration at the politicians failure to tackle rampant unemployment some two years after the Islamic State group was declared defeated. One of the demonstrators lamented the governments inability to provide him with even the lowliest job. I have a masters degree, but the government would not even hire me as a street sweeper. All of these young people are treated unfairly. Others railed at the culture of corruption that has seen the infrastructure of iraqi cities crumble. For now, the demonstrators remain without any clear leadership while their demands cut across sectarian lines. The government seems to have been taken by surprise by the fury on the streets. An effort to hold an emergency session in parliament to tackle the crisis had to be abandoned after key political blocs stayed away. The Security Forces may be able to contain the protests by force, but the anger of the demonstrators is increasingly directed at the Political Class as a whole, which so far has shown no sign of having a plan to deal with the underlying causes of the unrest. Sebastian usher, bbc news. This is bbc news, the headlines. Thereve been more protests in hong kong, as demonstrators defied a ban on face masks. Hong kongs leader has accused them of destroying the territory. The mother of a british teenager, killed in a crash involving a us diplomats wife, says the uk must put pressure on her to return to face justice. More now on our main story. The situation in hong kong. The situation has been getting worse. Victoria hoy is associate professor at Notre Dame University shes from hong kong and has researched the political situation there. Shejoins us now from indiana. Thank you so much for your time. First of all, what is your view on how the Hong Kong Government has treated the protesters, especially this facemask ban . The facemask ban has increased the tensions that have been going on for some time and then on october the ist everything actually basically reached another milestone because an 18 year old was shot with a live round. Fortunately he was not killed because the bullet went through between his long and his heart. But it has intention and two days later you have the facemask and and people are even more furious. These are Emergency Powers that carrie lam, the chief executive, has used in terms of banning the facemasks. How much further will she go . What you think we are going to see in the next coming weeks and months . People are very worried and also the establishment forces have been talking about also cancelling the upcoming District Council elections scheduled in november. And because of the immense public sentiment and currently the District Councils are dominated by pro beijing forces. People are talking about the government provoke in protest of ireland so they have an excuse to not just impose an ireland so they have an excuse to notjust impose an emergency but cancel the elections. If that happens then all the legal channels are completely raised then it is just going to basically set up even more. Just going to basically set up even more. You are busy think that the Hong Kong Government has gone about this in the wrong way. What can they do, given the protesters are quite angry and we have seen it go on for so angry and we have seen it go on for so long . Well, people have been really angry about Police Brutality which has also escalated a lot since june. So anywhere in the world where the Police Arrest even a murder on the Police Arrest even a murder on the spot we dont really beat that quy the spot we dont really beat that guy with a button to the point that the guy has internal bleeding and you dont break that persons knows and deny them access to their family for more than ten hours. In the Detention Centre they get further bone fractures. So this is what is going on in hong kong. The shooting of these two teenagers in the last few days, tensions. There is one easy way out because protesters have been calling for an independent investigation. If the government could do that that would really quieten things down. In terms of carrie lam and her actions, surely china is perhaps telling her what is a cce pta ble china is perhaps telling her what is acceptable and what isnt and that is what limits her actions. Is that the case . This is exactly why people are the case . This is exactly why people a re really the case . This is exactly why people are really upset. For them, they are not going home. Brutality. What kind of teenagers really want to risk having your brain and internal bleeding and bones broken . They think it is the end of hong kong. That basically carrie lam has no power and that this is beijings ruling from behind the scenes. And if they dont go home then the crackdown is going to be even more severe. Victoria, thank you very much for your insights. Six elephants have fallen to their deaths in thailand while trying to save each other from a notorious waterfall. A warning this report contains some upsetting images. Vince soodin reports. Motionless, still, and lifeless, the bodies of six elephants lie dead at the bottom of a waterfall known as hells abyss. Among them is the body of a three year old calf. The discovery was made in thailands Khao Yai National park, when rangers heard two surviving elephants crying close to the heartbreaking scene. It is feared the adult elephants died too when they tried to rescue the infant. The elephants were trying to cross the river. One of the smaller elephants might have slipped, and the adults were swept away by the current when they tried to rescue. A rescue mission was launched to save surviving elephants trapped on rocks above the churning waters. Rescuers threw food laced with supplements to boost their energy and give them the strength to climb back up into the forest. At the moment, the elephants are taking a break. They are quite tired from trying to cross over from the other side. They are just resting by standing still, because they have used up a lot of energy wading through the water. The waterfall, which claimed the lives of eight elephants in 1992, was closed to tourists as the operation took place. Now six more of the selfless, majestic beasts have fallen victim to hells abyss.

The competitive world of publishing has seen many titles come and go, but one monthly magazine has Just Launched its 500th edition after almost half a century. Gay times is now europes longest running lg bt publication and ben hunte has been looking at how its changed through the decades. Glossy magazines fill the shelves, but this one, which looks like coffee table art, started 47 years ago as a monthly voice for gay activists. Here in the national lgbt archives in east london, you will find a treasure trove of queer history. Almost half a century later, some of the pages still feel relevant today. One of the things we have seen within this magazine, within the first edition, is media watch. Can you just talk me through what media watch was . It was basically a look at what was being said in the National Media about the Lgbt Community at the time. Loonies who want a sense of family life. And even more relevant, save the children from sad, sordid sex lessons. Reading some of the headlines here, they arent too dissimilar to headlines that we actually see today. Of course, predominantly targeted at what was called the Gay Community then, but within lgbtq communities, some of these headlines being targeted towards people with a trans experience now, quite often in well known media titles. Today, the 500th edition has changed quite a bit. The magazine has diversified, and so has the business model. The magazine now really only represents a tenth of the gay times organisation. We work much more with the community and content channels across social and digital platforms, were the biggest lgbtq partner on instagram. In a woke world full of specialist publications, competition to represent communities, and make more money, is getting tougher. But activists say the platforms are more important than ever. Ben hunte, bbc news. Five years ago, lucia lucas thought her career was at an end, but now shes made history as the first transgender singer to perform with the English National opera in london. She transitioned in 2014, but continues to play male characters due to her deep baritone voice. Shes been speaking to our arts correspondent, david sillito. Hi. My name is lucia lucas and i am a professional opera singer. She sings opera. I am not trying to be a pioneer. I am trying to see how far i can get this to go and how long i can stay in the business because i hope that people in the future wont have the difficulties that i have had. Lucia lucas. It has been more than five years since she decided the time had come to be her true self. The director of the opera at the time said. Just one question what happens to your voice . I said it doesnt change. Ive done some research on that and for better or worse it doesnt change. And so with that baritone voice she makes the journey each evening from she to he. Tonight, a debut for English National opera. Ladies and gentlemen, you have 15 minutes. There you go. Thanks. On stage you play male roles. Is that uncomfortable . No, not really. It actually, in a certain way, justifies the difficulty that i had as a child because i knew that i was not team boy. Because youve always been acting. Ive always been acting but now ijust do it on stage. If it had been a choice of singing or being yourself . Be myself. 100 . I never envisioned that i could do both at the same time. You thought it would be the end of your career . Yeah, of course. Five years on, rather than ending her career, it has blossomed. Transitional hormones havent affected that extraordinary voice and tonight, a debut on the london opera stage, another barrier broken. David sillito, bbc news. A stunning operatic voice. Lets get the weather now with matt taylor. Hello. After a thoroughly wet night across many parts of the uk, there could be a lot of surface water, a lot of big puddles around if you are about to head out onto the roads on sunday morning. The greatest concern parts of central southern scotland, northern and eastern england, where the rain will be at its heaviest and most persistent first thing. And of course, with the ground saturated, that flooding could be a little bit worse. So be prepared for some travel disruption. This is the culprit, a weather front which has been pushing its way eastwards overnight. Ahead of it, some stronger winds, strong winds developing in its wake. But a lot more in the way of dry, clearer weather to the south and west later on. But lets focus on the rain band for the morning. It is going to be across much of scotland. Heaviest and most persistent through central and eastern areas, particularly towards those eastern coasts where there will be a gusty wind. Maybe turning a little bit more showery towards western scotland. Wet weather to the east of the pennines too. And the heaviest and most persistent rain will be down those eastern counties towards lincolnshire and east anglia. Some of the rain will have eased for the east midlands and the south east, but dont let your guard down. Some of that rain may return later on. West of that, a blustery day. The strongest winds to the south west and south wales. A few showers drifting through western scotland, north west england, north wales, and the midlands throughout. But here, generally a lot more in the way of drier and brighter weather compared with what we saw on saturday. A bright day towards the north east. But the north east to the south west, there windy conditions. And temperatures at the levels they should be for the time of year. They will feel cooler down those eastern coasts with the wind off the sea. Still some rain for a time as we go into sunday evening across central and eastern parts. That will fade away. Drier with some mist and fog forming. And then, later in the night, more wet and windy weather arrives back into the west. That will lift temperatures up into the start of monday morning rush hour. A little bit cooler, but at least drier to the east of the country. As we start monday, this is the chart. A big area of low pressure to the south of iceland. It doesnt look great, does it . And these weather fronts will bring persistent rain to start the day in western areas. Strong to gale force winds. They could become severe gale force in the north west of scotland. Outbreaks of rain, heavy and persistent in the morning. Turning a bit lighter and more fragmented as it heads eastward into the afternoon. So some eastern areas not quite as wet. But again, given the rain we have had, there could be some other minor flooding issues. Brighter weather to finish the day in the west, even though it still remains pretty windy in places. And a rather cool day too. And it sets us up for a really changeable autumn week. This is the jet stream pattern. A fairly vigorous one charging across the atlantic in this rough snaking pattern. On each little dip in thejet stream, we will see a subsequent area of low pressure. One after the other after the other. So it does mean wherever you are across the uk, rain will feature in many parts through this coming week. So never be too far away from those waterproofs. Bye for now. This is bbc news. The headlines. Most of hong kongs metro system remains shut after a day which saw
