Hello and welcome. 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 favors. They accused the president of defiance, obstruction and cover up. Our correspondent Chris Buckler is in washington. Chris, good to see you. Can you give us chris, good to see you. Can you give usa chris, good to see you. Can you give us a sense of the latest on this subpoena . Yeah, there have been a request for information and it has now become a demand and it is intended to put extra pressure on President Trump and the white house. Alongside the subpoena demanding all of these documents has come a letter from the chairman of three congressional committees. Leading democrats who, as you mention there, up democrats who, as you mention there, up until this point believe the white house has refused to engage with or even respond to multiple requests from documents from their committees on regular basis. As a result they are now issuing the subpoenas. As almost a month of stonewalling it appears that president has chosen. There are strong words and give you a sense that the battle lines have been drawn in washington as these impeachment enquiries 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 as opposed to a rough transcript that has been released of what President Trump exactly asked his ukrainian counterpart. Back in july. They want to know the full details of that conversation, they also want to know 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 zelinsky to investigate his political rivaljoe biden and this suggestion are potentially the white house had pressure on bite suspending military aid. That is firmly denied by the white house and we have a statement from the white house in this subpoena changes nothing, it is more document request, a waste of time and taxpayer dollars that will ultimately show that the president did nothing wrong. It feels that events a re did nothing wrong. It feels that events are always moving thick and fast. It comes off an already busy day, these revelations of text m essa 9 es 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 enquiry might. One of the Text Messages is been particular caught their attention and it is again about that question of suspending military aid, which america was involved with before that conversation between the president s. One diplomat said as i said on the phone i think it is crazy to withhold Security Assistance for help with a political campaign. We should say there was a text m essa g e campaign. We should say there was a text message back from another diplomat saying i believe you are incorrect about President Trumps intentions. The president has been crystal clear, no quid pro quo is of any kind. President trump said it wasnt a case of you do this for us and we will give you that. He said that wasnt the case. And he is continuing to say he has a right to investigate corruption and push for others to investigate corruption as the president of the United States. But at the same time, it should also be stated that he has shown absolutely no evidence of wrongdoing by Eitherjoe Biden or his son in a business interests in ukraine. Thank you for catching us up on all of those events of the day.

Hong kongs 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. Its 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 kongs 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 kongs 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 chinas 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 continue to burn. Rupert Wingfield Hayes, bbc news, in hong kong.

The former assistant of Robert De Niro is suing the actor for what she claims are years of gender discrimination and harassment.

In response, mr de niros lawyer said the allegations were beyond absurd. 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 iraqs 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 i6 among young people. Over a fifth of iraqis live on less than 2 a day. The government hasnt 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 wont 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 are such a dire economy, kind the government make the required reforms . Gareth barlow, bbc news. David mack is the former Us Ambassador to the United Arab Emirates and is now at the middle east institute in washington. It isa it is a wealthy country with an educated population, why are there so many problems . I think we have to see this in terms of very High Expectations after the overthrow of Saddam Hussein in 2003. That have not been met by either the Us Occupation and a few allies including the united kingdom, or by the succession of freely elected iraqi governments since then. Governments have faced similar outbreaks of dissent in the past, essentially, iraqis believe that democracy ought to bring more than just free media and elections. It ought to bring improved government services, clean water, electricity, better education, Better Health care and it ought to bring a lot more jobs for the increasing number of educated iraqis who are not able to find meaningfuljobs. Educated iraqis who are not able to find meaningful jobs. Despite educated iraqis who are not able to find meaningfuljobs. Despite the fa ct find meaningfuljobs. Despite the fact that iraq is a wealthy country, it has rapidly increasing Oil Production and it certainly looks to a lot of the iraqi people as if somebody is siphoning off that wealth. And they blame corrupt government officials. What responsibility does the United States have, or potentially Oil Companies that purchase iraqs oil, to come in and try and stop some of that corruption . Well, the United States has a lot of responsibility for mishandling the period when it was an occupying power and had the majority of the outside influence over the iraqi political system. It was not well handled and there is a lot of blame for that. That is certainly genuine and felt by iraqis. But since about, i would say, 2008, 2009, the predominant outside influence in iraq has been iran. And the parties that have been in control of the government are sheer religious parties, many of whom reflect considerable iranians influence. And so right now there is a lot of blame by the population of the Political Parties, their own iraqi Political Parties of iranians influence and of neglect by the United States and the rest of the international community. David, a very complicated picture you have ended there. Thank you very much. Stay with us on bbc news, still to come.

Thousands of protestors in hong kong have defied a government ban on face masks and held unofficial marches and rallies. 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. Its not yet clear when the princes 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 harrys 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 its 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 dont 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. 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. Heres 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. Theyve 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 cant 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. A new sculpture by the american artist jeff koons has been unveiled in paris. The bouquet of tulips was intended as a gift to the city in memory of the victims of 2015 terror attacks. But theres been a lot of criticism of the design with opponents saying its inappropriate, and the connection to the attacks isnt obvious. There was also a three year dispute over its location after it was feared the sculpture would interrupt views of the eiffel tower. Well, we can now speak to hrag vartanian, who is an art critic and editor in chief of the art publication hyperallergic, he joins us from new york. Thank you for your time. There were a lot of complaints about this sculpture. Can you take us through some of the main ones . People were really confused because there wasnt a public process to this sculpture. Try and understand why the victims themselves were not consulted or asked. People were wondering why it was placed near the art museum as opposed to the site of the attack. And there is a lot of confusion about this process. And now that it has been unveiled, i dont think a lot of those questions have been a nswered lot of those questions have been answered the people. The issues were raised in a 2016, i believe, when this sculpture was announced. It is extraordinary that some of them havent been dealt with or addressed. Absolutely. It is really kind of peculiar why this would happen quite this way. And when we interviewed one of the survivors of the attack, they were really perplexed why nobody was consulted. And what this process is. I think a lot of people feel that this is a very top down approach this monument, especially a monument which is supposed to speak to peoples pain. And such a communal, there was such a sense of community after the attacks, so people really hope that it would reflect that. There was also criticism ofjeff koons himself, wasnt there . There seemed to be this idea that it was being generous, but people had to manufacture, and i was millions of dollars are spent on the sculpture. So people were kind of wondering why it was done this way. And people considered jeff koonss sculpture. It seemed strange because he spoke about his own experience and his own issues that he has dealt with, Different Things like 9 11 in new york. But he wasnt really talking about the specificity of this incident. And people were hoping that that would be the case. Incident. And people were hoping that that would be the casem should be said, i have read that some victims have said nice things about the sculpture. But if there is about the sculpture. But if there is a long history of sculptures that get kind of negative feedback. What tends to happen . Did i get placed, or do theyjust kind of continue to exist . I think they tend to sort of exist . I think they tend to sort of exist and take on personas. In this case, we will find out whether it becomes some kind of instagram hit, or it becomes a place where people rally during times of mourning. These are things that we are going to discover in the coming weeks and yea rs. To discover in the coming weeks and years. That is something we will have to discover as time goes on. We simply dont know. But the other thing is people may be very upset after a while. And who knows what the upkeep of these things can be. Especially if there is vandalism or damage. So we will have to wait. We are going to have to wait. Hrag vartanian, art critic, thank you so much for your time. Vartanian, art critic, thank you so much foryourtime. Chatting vartanian, art critic, thank you so much for your time. Chatting about that you sculpture in veiled unveiled in paris to commemorate the victims of the 2015 terror attacks.

Stay with us. Hello, as one weather system clears, another comes in from the atlantic. It doesntjust 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 part 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 front comes in from the atlantic, 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 apm, 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.
