welcome to bbc news. president under pressure, democrats issue a legal demand to the white house for documents relating to an impeachment inquiry. hundreds of protesters join unoffical rallies in hong kong, defying a government ban on face masks. the white house has been ordered to hand over documents relating to the impeachment investigation of president trump. a statement from the heads of the democratic—led inquiry committee said they sent a letter

to the acting white house chief of staff, mick mulvaney, demanding evidence related to allegations that mr trump pressured ukraine for political favours. they accused the president of defiance, obstruction, and cover—up. i asked our washington correspondent, chris buckler, what more we know about the subpoena. there had been a request for information, that has now become a demand. and it is intended to put extra pressure on president trump and the white house. and alongside this subpoena demanding all of these documents has come a letter from the chairmen of three congressional committees. leading democrats who, as you mentioned there, say that up to this point, they believe the white house has refused to engage with or even respond to multiple requests for documents from their committees on a voluntary basis. as a result, they are now issuing these subpoenas. and they say after nearly a month of stonewalling, it appears clear that the president has chosen the path of defiance, obstruction, and cover—up. those are very strong words, and gives you a sense of the battle

lines being drawn in washington as these impeachment inquiries continue. beyond that, we also have some idea of what they are looking for here. because what they requested back in september was a whole range of different things, including the full transcript, as opposed to a rough transcript that had been released, of what president trump exactly asked his ukrainian counterpart, president zelensky, back injuly. they want to know the full details of that conversation. they also want to note for example of any and all records connected to anything that was about the actual or potential suspension of security assistance to ukraine. and, of course, this is all about president trump asking president zelensky to investigate his political rival joe biden, and this suggestion that potentially the white house had tried to put pressure on by suspending military aid. of course, that is firmly denied by the white house. and, in fact, we have a statement from the white house press secretary this evening that says, "this subpoena changes nothing.

"it is just more document requests, wasted time, and taxpayer dollars "that will ultimately show that the president "did nothing wrong." now, chris, it seems like events are always moving thick and fast. it comes off the back of an already busy day, these revelations of text messages between american diplomats. yeah, and you get the idea that the democrats are pushing to try and investigate every avenue they can. and these text messages came after one of those impeachment inquiries involving those three congressional committees. now, one of the text messages has particularly caught their attention, and it is again about that question of suspending military aid, which america was involved with before that conversation between the presidents. and one of them, a senior us diplomat in ukraine bill taylor, said, "as i said on the phone, i think it is crazy to withhold "security assistance for help with a political campaign." and we should say there was a text message back from another diplomat saying, "i think you are incorrect

"about president trump's intentions, the president has been crystal clear "no quid pro quos of any kind." and that is the message that is coming now from the white house. president trump said it wasn't a case of, "you do this for us, and we will give you that." he says that wasn't the case. and he is continuing to say he has the right to investigate corruption and push for others to investigate corruption as a president of the united states. but at the same time, it should also be said that he has shown absolutely no evidence of wrongdoing by eitherjoe biden or his son hunter who had business interests in ukraine. chris interests in ukraine. look like they're taking us through chris look like they're taking us through very fast—moving events. doctors in the united states have confirmed that the us senator and left—wing presidential contender, bernie sanders, had a heart attack on tuesday. mr sanders was released from hospital in las vegas on friday, and issued a statement saying he was feeling great. the 78—year—old suspended his campaign after having an operation on his heart, during which stents were successfully inserted.

hong kong's entire metro system has been shut down following violent demonstrations by thousands of protesters, who defied a newly—imposed ban on wearing face masks in public. it's the first time the whole network has been closed since the unrest began four months ago. demonstrators lit fires outside several stations, and attacked businesses and banks linked to china. police responded with live ammunition and tear gas. rupert wingfield hayes reports from hong kong. hong kong's chief executive made her whole cabinet stand with her and face the cameras together, visually declaring their support for the dramatic step she was about to take. we believe that the new law will create a deterrent effect against masked violent protesters and rioters. and will assist the police in its law enforcement. the objective of this regulation is to end violence and restore order

and i believe this is now the broad consensus of hong kong people. that is certainly not what it looked like on the streets outside. in hong kong's central business district, news of the facemask ban brought angry office workers onto the streets in their hundreds. they tore down a giant banner celebrating communist china's 70th anniversary. rapidly put it to flame. within hours, the numbers on the streets had swelled from hundreds to thousands. carrie lam has told the people of hong kong, "if you come out "on the streets tomorrow wearing masks, you will be a criminal." well, this is their response, they are furious, and they are challenging her and her government to do their worst. this young woman did not want to show her face, butjust listen to her anger. we are not afraid of this unlawful

act, and we will tell the government that we will not surrender because of their suppression. and also the government because they are pro—beijing. we are hong kong, we should be given the democracy to rule, the rule of law. attacks on police by masked protesters, like this one on tuesday, is the reason the government says it has been forced to bring in the facemask ban. but tonight, it seems to be making the violence even worse. this is video of a policeman under attack in a town. the officer has fired his gun. now the protesters respond with petrol bombs. as the midnight deadline passed and the new facemask law came into effect, the tear gas grenades continued to rain down. the streets continued to burn. rupert wingfield hayes, bbc news in hong kong. let's get some of

the day's other news. anti—terror police have taken over an investigation into a knife attack at the police headquarters in paris on thursday. four police employees were killed by a worker — who was shot dead at the scene. the european commission says britain's latest proposals an agreement". meanwhile, uk government papers submitted to a scottish court suggest that prime minister boris johnson will ask for a delay to brexit. buckingham palace says prince harry has begun legal action against the owners of the sun and the daily mirror newspapers, in relation to alleged phone—hacking. it's not yet clear when the prince's allegations date from, but in a phone—hacking criminal trial in 2011, he was named, along with prince william, as a victim. his move follows the announcement earlier this week that his wife meghan was taking a separate legal action against the mail on sunday.

our royal correspondent, johnny dymond, reports. all smiles at the end of a high—profile tour. but in the works, a legal bombshell. harry is suing two of the biggest newspaper groups in britain. mirror group newspapers, publishers of the daily mirror, and news group newspapers, which publishes the sun, and the now closed news of the world, are the defendants. the case: allegations of harry's calls being hacked in the early 2000s. the news of the world closed down as a result of phone—hacking revelations. its owner paid out huge sums to celebrities, as has mirror group newspapers. i think it's because prince harry has declared a one—man war against the tabloid press, an ill—advised one. i am not defending phone hacking in any shape orform. but the timing is so significant,

and i know there is division between senior royals and their advisers over the wisdom of what he has done. the news comes just two days after it was revealed that meghan is taking legal action against another newspaper — the mail on sunday — for publishing a letter she wrote to her father. as that was announced, harry launched an angry and deeply personal attack on the tabloid press, and what he said was its ruthless campaign against his wife. royals rarely reach for a lawyer or a writ, and the reason is it is such a high—risk strategy. they can be cross—examined, they can also have disclosure go to places that they don't really want. so it is a very high—risk strategy. things are outside their control. it is also a high—risk strategy for the editors who are going to have to give evidence too. the royal family is always high profile, but harry has pushed back before.

the metropolitan police has issued an apology after its investigation into an alleged vip paedophile ring was heavily criticised by a review. it said officers were too quick to believe accusations by carl beech, who was later jailed for lying. he's now serving an 18—year prison sentence. our home affairs correspondent, june kelly, reports. among the many figures carve each named was lord bramall. also lord britain who had served as home secretary. the ex conservative mp laura proctor. and the x prime minister edward heath. and edward jana. in police interviews, kyle beach claimed these men were part of a high profile paedophile network in

the 70s and 80s who sexually abused and tortured boys. he even said he had witnessed three boys being murdered by the group, one hit by a car. it was in october 2012 that carl beech first made limited abuse claims to wiltshire police, there was no action. injuly 2014, carl beech met labour mp tom watson after he made wider claims online. by december that year, scotland yard we re december that year, scotland yard were investigating describing carl beech's claims as credible and true. thisjudge was beech's claims as credible and true. this judge was brought in to review the scotland yard enquiry. his findings detail one of the most damaging episodes in the modern history of the metropolitan police. but today, the force refused to do any interviews, instead there was this statement. i am deeply deeply

sorry for the mistakes that we made, and for the ongoing pain these m ista kes and for the ongoing pain these mistakes have caused. i promise we will do everything we can to to prevent it happening again. steve rod house was the officer who headed the investigation known as operation midland. now in a topjob outside the metropolitan police, he is castigated on a number of fronts in today's report. this includes sanctioning the phrase credible and true to describe the allegations from carl beech, then known by the pseudonym nick. thejudge says in his review... the police team are described as being under pressure from tom watson, a campaign on child abuse. 0ne detective describes the politician as a priority. the review says...

harvey proctor had and his job because he was under suspicion. today, he said tom watson should resign as deputy labour leader and be expelled from the party.|j resign as deputy labour leader and be expelled from the party. i have co nte m pt be expelled from the party. i have contempt for carl beech. it is matched with my icy contempt for tom watson, and the labour party should immediately disassociate themselves from mr watson. what has operation midland done to you?|j from mr watson. what has operation midland done to you? i have no money, no resources, i cannot plan my future, i am not sure money, no resources, i cannot plan my future, iam not sure i money, no resources, i cannot plan my future, i am not sure i have a future. tom watson insists the review contains multiple inaccuracies. can i get your reaction please? are you going to resign? but there was no further comment for the cameras today.

another of the falsely accused, lord britain, died during the police investigation. never knowing that he had been exonerated. 0fficers investigation. never knowing that he had been exonerated. officers are accused of unlawfully obtaining wa rra nts to accused of unlawfully obtaining warrants to search suspects' homes. today's review criticises the contact some journalists, including the bbc, had with carl beech. 0verall, the bbc, had with carl beech. overall, this case has raised questions about the competence of the country's largest police force and its independence in the face of political pressure. june kelly, bbc news. this is bbc news, the headlines... democrats have issued a legal demand to president trump's chief of staff for documents relating to an impeachment inquiry. thousands of protestors in hong kong have defied a government ban on face masks and held unofficial marches and rallies.

iraqi officials say at least 60 people have died during four days of anti—government protests. nearly 200 have been injured. many of the deaths occurred on friday, including those of at least two policemen. in central baghdad, gunfire erupted as the security forces confronted a group of demonstrators. gareth barlow reports. funerals for some of those killed during iraq's protests. increasing anger against the government is proving deadly. the violence in majority shia regions is the worst in recent years. for days, crowds have defied the authorities and curfews to challenge corruption and unemployment, which is at 16% among young people. over one fifth of iraqis live on less than $2 a day. the government hasn't stood up for me. i am only living with the help of god. no housing, no salaries, and i am

a graduate with five languages. this is a country of nepotism. the poor have no link to the parties. who speaks on behalf of all those people? as the violence attracts international concern, the influential cleric and political figure muqtada al—sadr called for fresh elections. the government promised reform. tomorrow, the parliament will meet, and these committees will start work. we won't wait long to approve these reforms which will come from the council of the government and from the parliamentary committees. we will remove the government from office, this man said, even with our last breath. but with such determination, and such a dire economy, can the government make the required reforms? gareth barlow, bbc news. let's get more now on brexit.

the government has acknowledged for the first time that borisjohnson will send a letter to the eu asking for a brexit delay, if no deal has been reached by the 19th of october. the details were included in papers submitted to the court of session in edinburgh, where campaigners are seeking a legal ruling to ensure the prime minister complies with the an act passed by mps last month to prevent a no—deal brexit. 0ur scotland correspondent, lorna gordon, said that given everything else that we know, this is something of a surprise. the prime minister has previously said he would rather be dead in a ditch than ask for an extension to the brexit deadline. he has also said he will obey the law. but here at the court of session today, we learned two things, really, we learnt that the government will write a letter is required by the benn act, asking for an extension to the brexit deadline if no deal is in place by october the 19th. we also learnt that it will be the prime minister

who writes that letter. clea r? well, not exactly. because as this was going on, borisjohnson was tweeting on social media saying new deal or no deal, but no delay. downing street was also briefing that the country is not prevented from leaving at the end of october, adding that the government will make its true position on the delay — is making its true position on delay known privately in europe, and that this will become public very soon. well, those who brought this case to the court here argued in court today that their position is that borisjohnson is not an honest man. they pointed to some of his contradictory statements over the past few weeks, saying that these are why they think the court needs to issue a legally binding order to compel the prime minister to comply with and not frustrate the benn act. we expect the judge here to issue his decision on monday. we expect another court case to follow very shortly thereafter.

well, as the investigation deepens, so do divisions in america. with the presidential election just over a year away, the battle lines between democrats and republicans are drawn, and the stakes couldn't be higher. aleem maqbool reports from california on how both sides are reacting to recent events. there are many on the left in america hopeful donald trump could be removed from office. at a town hall meeting in california, democrats gathered to hearjohn dean, the whistle—blower who helped bring down president richard nixon. this president is making richard nixon look like a choir boy. the idea of donald trump's impeachment appears to be galvanising grassroots democrats. calling another world leader and asking them to interfere with our election, it is disloyal, it's unpatriotic. it makes me worried

and angry for our democracy. for me and i think all the other people here today, my neighbours and friends, we really want to see impeachment move forward. you have to wonder why the leftist dems are pushing so hard to impeach. the media forgets that they have been screaming for impeachment since the election... the impeachment issue appears to be energising those on the right as well. this is a meeting of trump supporters in beverly hills, angry about the impeachment inquiry. i think most people don't think it's absolutely an attack on donald trump, it is really an attack on the people who voted for donald trump. i am kind of sad because i think it is not authentic and at the end of the day i love my country, and i would like impeachment to be reserved for the most serious of situations. the guest speaker at this conservative gathering was an activist and street artist on the far right.

he is a trump supporter on the extremist fringes who thinks the impeachment inquiry will only help the president. it is going to enrage the right. you're only going to infuriate the right. bring more voters out. if you think for one second someone is going to say, "oh, my god, "donald trump is colluding with ukrainians," it is not going to happen. democrats say impeachment is simply about the president having committed a crime. many republicans tell us that it all has to do with the left still being unable to accept the election result of 2016. aleem maqbool, bbc news, in los angeles. the award—winning american actress diahann carroll has died at the age of 84. she starred in the 1960s tv showjulia, the first us sitcom to feature a black woman in the lead role. she was also the first black woman

to win a tony for best actress in 1962 for the broadway musical no strings. in the 1980s, she went on to play the scheming dominique deveroh in tv hit, dynasty. a french man has been able to move all four of his paralysed limbs using an exoskeleton suit controlled by his mind. the 30—year—old was paralysed from the neck down after falling 15 metres in a night club four years ago. he said using the exoskeleton made him feel like being "the first man on the moon." here's our medical correspondent, fergus walsh. this is mind controlling machine. thibault, who was paralysed in all four limbs, is sending instructions to his exoskeleton suit using brain signals. the movements may bejerky, but it is a significant technological achievement. the study in the journal lancet neurology explains how thibault had surgery to place two

5cm implants on the outer membrane of his brain, above the areas which control movement. electrodes read his brain activity then beam messages to a computer which converts them into instructions for the exoskeleton. thibault practised by learning to control an avatar in a computer game, and then gradually mastered increasingly complex movements. this is a brain—computer interface... scientists at imperial college london are pioneering uk research into implants. they've praised the french exoskeleton study as ground—breaking. this is a very important and significant step. usually it has been demonstrated through a movement ofjust a single limb, and in this case they have demonstrated all four limbs simultaneously, although the complete exoskeleton was still attached to the ceiling,

so many other elements are missing, such as balance. any device implanted in the body carries the risk of infection, but the potential benefits are huge. the technology that merges brain, body, and machine is moving at a rapid pace. as well as paralysis, there are potential applications for implants in the fields of epilepsy, even depression. 0ne team here at imperial is even working on a gut implant to suppress appetite to control obesity. the exoskeleton can't yet be used outside the lab, and the technology is so expensive it will be out of reach of most of those with spinal—cord injuries. but, as a proof of concept, it is an impressive step forward. fergus walsh, bbc news. let's get the latest weather

prospects now with nick miller. hello, as one weather system clears, another comes in from the atlantic. it doesn'tjust sum up the weekend weather across the uk, but pretty much the next seven to ten days out there. here is the next weather system coming in. as we go on through saturday into sunday, here is the next one that will come in on monday. so more rain to come this weekend, not a wash—out though. there will be some drier, brighter skies either side of an area of rain that will be quite heavy at times as it spreads its way eastwards. now, this is how we start on saturday morning, quite chilly across the eastern side of the uk where we have had clear skies overnight. there may be a touch of frost in the coldest parts of north—east scotland, and where it has been clear, there could be some mist and fog patches, perhaps dense in a few spots, gradually clearing during the morning. any early sunny spells in the east replaced with increasing cloud as that weather system comes in from the atlantic, initially some quite light rain further east but notice how there is some heavier rain coming in toward western parts as we go on through the afternoon. here is a look at things at 4pm, you can pick out a temperature

near you, the wind speeds as well. there will be a strengthening south—easterly wind. you will also see that the far north—east of scotland is still dry, still some sunny spells around into the northern isles, but a wetter picture through northern ireland, much of western scotland and some outbreaks of rain with some heavier bursts into western parts of england and wales. and again some patchy rain feeding east ahead of that with thickening cloud. and that rain will get heavier still as we go on through saturday night and into sunday. in fact, some brighter colours showing up on the rainfall forecast here. so there will be some reasonably high rain totals going into sunday as that turns more widespread, slowly pushing further east on what will be a mild night going into sunday morning. so the big picture then for part two of the weekend shows that frontal system with the rain, heavy at times, right across us and in no hurry to clear away eastwards on sunday. although behind it where it does clear, a little ridge of high pressure briefly coming in, before that next system as it turns wet and windy again on monday. this is how sunday is looking, and the yellow triangles indicating

where the met office has yellow warnings for rain. parts of scotland, the eastern side of england. there could be 15 to 30 millimetres, maybe a bit more in the wet spots, the risk of some flooding and some travel disruption in a few places. and this weather system just easing a bit on through sunday afternoon but still giving outbreaks of rain here. most likely to break out into brighter skies on sunday in northern ireland, wales, and south west england. now, i mentioned that next weather system coming in on monday, there will be more to come next week. it will often be windy, wet at times. not all the time, there will be some occasional sunshine as well, but basically autumn — full throttle.

this is bbc news, the headlines... the white house has been

ordered to hand over documents relating to the impeachment investigation of president trump. the heads of the democratic—led inquiry committee said they sent a letter to the acting white house chief of staff demanding evidence related to allegations that trump pressured ukraine for political favours. thousands of protestors in hong kong have defied a ban on face masks and held rallies demanding political reforms. earlier police fired tear gas at protesters who'd attacked buildings, including chinese banks. the territory's entire metro network was shut down — the first time since the unrest began four months ago. prince harry has begun legal action against the publishers of two newspapers for alleged phone hacking. this comes just days after his wife, meghan, announced she was suing another newspaper for publishing one of her letters. it is 3:30am.
