this is bbc news, i'm lewis vaughan jones. our top stories: donald trump under pressure — democrats issue a legal demand to the president's chief of staff mick mulvaney for documents relating to an impeachment inquiry. thousands join unplanned protests in hong kong and defy a government ban on face masks. the duke of sussex is to take two british newspapers to court over the alleged illegal interception of voicemail messages. and the revolutionary technology that's allowed a paralysed man to move again.

hello, and welcome to bbc news. we start with some breaking news, and that is that 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 democrats led enquiry committee said they sent a letter to acting white house chief of staff mick mulvaney demanding evidence relating to allegations that trump pressured ukraine for political favours, and they accused him of defiance, obstruction and cover—up. we can speak to the bbc‘s chris buckler in washington. this is moving quite quickly. we spokejust washington. this is moving quite quickly. we spoke just one hour ago and there was lots to pick through then. now, talk us through what has happened? i said then the talk was about impeachment here in washington as the sun went down. now the sun has gone down and we have a

development from the democrats. these are the chairman of three congressional committees, and they have all written together demanding that the white house releases a number of documents that they requested just under one month ago. in this letter, as you mentioned there, they said they believe the white house has refused to engage with or even response to multiple requests for documents from the committees on a voluntary basis. after nearly a month of stonewalling, it appears clear, and this is their words, that the president has chosen a part of defiance, obstruction and cover—up. very strong words, but it also gives you a sense they are determined to get these documents and push ahead with these impeachment enquiries. now, you have to go back to another letter, but a letter at the start of september, to find out exactly what they want. having looked at it, they want, for example, a transcript of president from's call with ukrainian president, volodymyr zelensky, back onjuly 25. president, volodymyr zelensky, back

on july 25. now, president, volodymyr zelensky, back onjuly 25. now, you will remember that a transcript has been released, and president trump has said time and president trump has said time and time again that he believes that the words in it clear him of any wrongdoing. he has described it has a perfect call. but actually, what has been released as just a rough transcript, and apparently the transcript, and apparently the transcript was put into a secure server transcript was put into a secure server inside the white house, and the suggestion is that the democrats wa nt to the suggestion is that the democrats want to find out everything that was said on this phone call. in terms of the other documents they want, there isa the other documents they want, there is a very wide range of them, which date back to january 20, 2017. some of the other key ones are, they want any records generated or received by any records generated or received by any white house staff in connection with, that refer or relate in any way, to the actual or potential suspension of security assistance to ukraine. and that is because this central allegation against president trump, which he has denied time and time again, is that he in some way tried to say that essentially, they

would stop providing security assistance unless an investigation was launched into his political rival, joe biden. there is also a request for personal documents relating to his attorney rudy giuliani, and potentially there will be lots for democrats to look at as they push ahead with these impeachment enquiries. that is interesting. thank you for talking us interesting. thank you for talking us through that. so we essentially have what was a request for information from the white house is 110w information from the white house is now turned into a demand, just in the last few minutes. 0bviously now turned into a demand, just in the last few minutes. obviously the white house has not responded yet, but what will their response have to be now? well, ultimately, this could end up in a legal battle, if they don't want to hand over these documents. there is certainly a great deal of power, as far as the congressional committees are concerned. they can demand this kind of information. it doesn't necessarily mean we will not see a legal fight over necessarily mean we will not see a legalfight over this, necessarily mean we will not see a legal fight over this, or certainly some delays. but it also gives you the sense that they are determined to push ahead with these inquiries

into impeachment, and this will retain the pressure on president trump, and it is very clear over the last few days that he is, to some extent, feeling that pressure. yes, he has got a new strategy, yes, he is coming out fighting, saying he has every right to demand enquiries into corruption, he has every right to demand that, even from foreign governments, but there is this big question, because ultimately it is against the law in the united states to get something from a foreign government that could interfere with aus government that could interfere with a us election, and of course what he has been asking for, time and time again, from the ukrainian government, is an investigation into joe biden and his son hunter's business dealings, and joe biden, it is worth remembering, is the frontrunner at the moment to be the democratic candidate to face him next yea r‘s democratic candidate to face him next year's presidential election. chris, thank you, a significant development in a day of significant developments. that was chris buckler in washington. well, as the investigation deepens, so do divisions in america.

with the presidential election just over a year away, the battlelines 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. applause. 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 and 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. you're only going to 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. republicans tell us that it all has to do with the left still being unable to accept the election result of 2016. 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.

hong kong's chief executive made her hold 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 a 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. chanting. 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 and rapidly put it to flame. within hours, the numbers

on the street 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. they fired tear gas. 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 authoritarian government, because they are pro—beijing. we are hong kong. we should be given the democracy to rule by 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 a video of a policeman, under attack in the town ofjianlong. 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, tear gas grenades continued to rain down. the streets continued to burn. iraqi officials say at least sixty 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. iraq's most senior shia cleric, ayatollah ali al—sistani, has urged the government to respond to the demands for reform. gareth barlow reports.

buckingham palace has said that prince harry has begun legal action against the owners of the sun, the now defunct news of the world, and the daily mirror, 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, 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 think. i'm not defending phone hacking in any way, shape or form, 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 that it's 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 for things that are outside their control, but it's also a high risk strategy for the editors, who are going to have to give evidence too. the royalfamily is always high profile, but harry has pushed back before. stay with us on bbc world news. still to come, discovering the rhythm of rwanda. one music producer has searched the globe looking for the voices and stories which capture a country's tale.

this is bbc news, the latest headlines: democrats have issued a legal demand to the president ‘s chief of staff 01’ to the president ‘s chief of staff or documents relating to impeachment enquiries. thousands of protesters in hong kong have defied a government plan on facemasks and held unofficial marches. let's stay with that story. the chinese ambassador to the uk, liu xiaoming, has been speaking to the bbc‘s newsnight programme. he was asked if he had confidence in carrie lam's ability to resolve the protests in hong kong. hong kong and the hong kong police are handling the situation. but we know there are paramilitaries in hong kong at the moment and according to reuters they are increasing. no. so my point is that people fear for their lives. they feel this is their only alternative. they want carry lamb gone, they want

an enquiry into police brutality and they want suffrage. will they ever get universal suffrage? the government has reaffirmed commitment to one government —— 102 systems typically repeated this on the eve of chinese national day that we are committed to one country to systems. and hong kong people, hong kong will continue to enjoy a high degree of autonomy. that is a very firm commitment. but the mainly in -- mainland chinese government will never take over in hong kong? that commitment has been made for 50 yea rs commitment has been made for 50 years in the policy will remain for 50 yea rs years in the policy will remain for 50 years and we are committed to it. a frenchman 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 50 feet 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. one 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. now for all record producers, finding new musicians is a constant quest but for ian brennan and his wife marilena delli the hunt has taken them further than most. from prisoners in malawi to genocide survivors in cambodia they have given voice to many who might not otherwise be heard. recently we spoke to ian about their music and his new book silenced by sound.

he sings when we went to rwanda the first time in 2009 we looked for music. that is what we do. we look for over two weeks and we saw hundreds of artists and bands. in the last few days when we were losing her we met adrian. —— losing hope. from 50 yards away i saw him and i knew that this was it. ijust knew it. it was incredible. i asked this was it. ijust knew it. it was incredible. iasked if this was it. ijust knew it. it was incredible. i asked if he had more songs and he said yes. i asked if he had people he played with and he said he would come back tomorrow with someone. we recorded the record right there and then. it was a movie scene, it felt like. the light came down and showed us what we had been looking for. do good with these people. their tour commemorates the 25th anniversary of the 1994

genocide. in 1978 when they were youngsters, children, they were taught music by their brother, who was blind and a gifted musician. he was blind and a gifted musician. he was someone lost in the genocide. following the genocide they gave up on music. they responded with despair. but after a period of mourning they decided instead that they would honour him by going out to find —— found a band and shared this and love through music. we have had the good fortune to be here on tour together for my new book in their forthcoming tour together for my new book in theirforthcoming record. there are many guests on the new record. from

wilco, from my bloodied valentine, but that is not what makes the record good. it just but that is not what makes the record good. itjust makes it even better than it already is. part of the amazing nurse and beauty of the band is adrian ‘s songwriting which is routes writing at its best. true roots writing. because he is from rwanda and does not sing in english he is put in a box of worldmusic. and that is tragic and ultimately theissueis and that is tragic and ultimately the issue is when people are not listened to, when they are not allowed to come to the country, as these guys were, they were denied. they are not cheated, the listeners are cheated. so part of the beauty is his writing on the other part is the harmonies. they sing together in a way that only people who have sung together for ever a way that only people who have sung togetherfor ever can. so a way that only people who have sung together for ever can. so people like the jackson 5 or the everly brothers, the carter family, like the jackson 5 or the everly brothers, the carterfamily, great harmony vocals. it is really

and fog patches, dancing a few spots, through the morning. the listening skills in the east with replaced with cloud as the weather system replaced with cloud as the weather syste m co m es replaced with cloud as the weather system comes in from the atlantic. light rain feeds further east notice heavy rain coming in towards western parts as we go on through the afternoon. this is a look at things at four o'clock. you can pick a temperature near you in the wind speed as well. strengthening south—easterly wind as well and are north—east of scotland is still dry with only spills around into the northern isles but a wetter picture through northern ireland and much of western scotland and some outbreaks of rain with heavy burst into western parts of england and wales. again, patchy rain feeding he is the head of the. that rain will get heavier still as we go on through saturday night and into sunday. some brighter colours showing up on the rainfall forecast. reasonably high rainfall forecast. reasonably high rain totals going into sunday. and that becomes more widespread, pushing further east. it will be a mild night going into sunday morning. the big picture than for
