welcome to bbc news. theresa may has called a special cabinet meeting tomorrow to discuss the government's response to the suspected chemical weapons attack in syria. sources have told the bbc that the prime minister is prepared tojoin the us in military action without seeking pa rliament‘s approval first. president trump has warned russia to ‘get ready‘ for missile strikes against syria. president putin said he hoped that common sense would prevail in international relations. our north america editor jon sopel reports. they're getting out of harm's way. from surviving the hell of eastern ghouta and the alleged chemical weapons attack, these refugees have buses to take them away, but to a still uncertain future. translation: we lived through very difficult times in eastern ghouta, especially the final three days in douma, when the regime carried

out its attacks on civilian neighbourhoods and used chlorine gas, which caused suffocation among civilians. and it's notjust refugees. according to many accounts, syrian soldiers are on the move as well, temporarily abandoning barracks ahead of any us—led attack. the threat of military action brought this warning from one of russia's most senior diplomats in the region. translation: if there is a strike by the americans, then we point to the declarations made by president vladimir putin and the russian military leadership that the missiles will be downed, and even the sources from which the missiles were fired. but those comments have the effect of goading the president, and this incendiary tweet. and at the defence department, they're preparing for all eventualities. we're still assessing the intelligence, ourselves and our allies, we're still working on this.

we stand ready to provide military options if they're appropriate as the president determines. although a slightly more conciliatory tone later from the president, when he said... a year ago, the us military launched a one—off cruise missile attack on a syrian airfield. it seems as though the us is preparing for something more extensive and more sustained this time, and with other nations involved. the ayes to the right, 272, the noes to the left, 285. five years ago, when barack obama was president, plans for military action by the us fell apart after the british parliament voted against such a move. but it looks as though this time around, theresa may is giving her american counterpart the nod there'll be no such impediments. all the indications are that the syrian regime was responsible, and we will be working with our closest allies on how we can ensure that those

responsible are held to account, and how we can prevent and deter the humanitarian catastrophe coming from the use of chemical weapons in the future. the strident language we're hearing from both sides is, frankly, more akin to two heavyweight boxers trash talking ar the weigh—in before a bout. but leaving the words to one side, there are the wider strategic questions. what is american policy now toward syria? does it support regime change? does it want further involvement or to pull out? on those questions, we're none the wiser. jon sopel, bbc news, washington. our deputy political editor john pienaar has more on the cabinet meeting tomorrow. it is already clear tonight that the prime minister is poised to see

britain involved in military action. she has good said so today when she spoke about the need to prevent and deter another chemical attack. today, the prime minister has been working hard to keep up with donald trump. those tweets landed with quite a thud in whitehall. the labour leader, jeremy corbyn, has been saying today that any military action should require parliamentary approval in advance. but one thing we are being told is that the prime minister is perfectly prepared to contemplate taking action in doing so contemplate taking action in doing so without getting that prior approval. she believes that action is urgently needed to prevent another possible chemical attack. she is also reluctant to ask donald trump to hold while she thinks that approval here in westminster. you may think of the prime minister, generally, as being a cautious leader and she is. defence now seem to be moving along under their own momentum and quickly. yulia skripal who was poisoned by a nerve agent in salisbury last month,

has released a statement rejecting help from moscow. the russian citizen was discharged two days ago from the hospital where herfather, a former spy, is still being treated. our security correspondent frank gardner has more details. we have no access, nobody does, to yulia skripal. she is in a secret and secure location, presumably some sort of country house, under police protection, probably armed police protection. i have been assured that the decisions went into the wording of this were 100% hers did it they are significant. she is unequivocal ina are significant. she is unequivocal in a statement. she says that she does not wish to be contacted by the media, by the russian embassy and not by her cousin, victoria. her cousin is in russia and in that was a surprise telephone conversation between the two of them. it is quite significant that she's says victoria

does not speak for her nor for her father. she says she is still recovering and her father is not well. her life has been turned upside down by this and she is yet to decide where she is to go from here but for now she has refused russian consular access. the russian embassy has responded already and said that it is beginning to look more and more like a forced detention. the russian embassy does not accept that yulia skripal is speaking her own mind, they think she has been forced to say this stuff and being kept apart. that is not what british government officials are saying. the founder of facebook, mark zuckerberg, has revealed he was among the millions of users, whose data was shared with the british firm cambridge analytica. he made the disclosure during his second day of questioning by law makers in washington. he also rejected claims that users don't have enough control over their data, on the world's largest social media network. here's our media editor amol rajan. seconds out, round two. mark zuckerberg's second testimony in as many days promised to make

amends for the first. yesterday, meandering questions and blatant ignorance about how facebook actually works led to a poor show by congress. today had to be better, and there were flash points. let me ask you. is it true that facebook offered to provide what i guess you refer to as dedicated campaign embeds to both of the presidential campaigns? congressman, i can quickly respond to the first point... were there embeds? were there embeds in the two campaigns? congressman... yes or no? time and again, the rigid structure inhibited lawmakers. with just four minutes each, they often overlapped and failed to pin him down. where does privacy rank as a corporate value for facebook? congresswoman, giving people control of their information and how they want to set their privacy is foundational to the whole service. it's not just an add—on feature or something we have to comply with.

the reality is, if you have a photo... if you just think about this in your day—to—day life... no, i can't let you filibuster right now. the attacks grew more pointed and personal. the 33—year—old billionaire was accused repeatedly of being, in effect, a spy. you're collecting medical data, correct, on people that on are on the internet whether they are facebook users or not, right? congresswoman, yes, we collected some data... and you're collecting, you watch where we go. facebook also gathers the data about where we travel. isn't that correct? congresswoman, everyone has control over how that works. i'm going to get to that, but yes, you are. would you just acknowledge that yes, facebook is? that's the business you're in, gathering data and aggregating the data? congresswoman, i disagree with that characterisation. then came a revelation. was your data included in the data sold to the malicious third parties? your personal data?

yes. it was. for now, the significance of any mistakes zuckerberg made remains unclear. through nearly ten hours of grilling, he kept his composure. i don't suppose you want to hang around for another round of questions? just kidding. zuckerberg's interrogation generated over $17 billion for shareholders. that's around one and a half billion dollars an hour, not bad, even for silicon valley. the past 48 hours were a missed opportunity for american lawmakers that showed why global governance for the tech giants is so hard. regulators are inherently parochial, whereas the companies are international. and frankly, there is often a generation gap that is between politicians and the precocious entrepreneurs of silicon valley. gridlock in congress means new data laws coming from brussels next month rather than washington. that should worry zuckerberg most. but he'll sleep easier tonight. amol rajan reporting there. more than 200 people on board a military aircraft have died, after the plane crashed in algeria. state television said that it came

down shortly after take—off, near the capital algiers. there are reports some people were killed on the ground. sophie long reports. the burnt—out fuselage of the ilyushin military transport plane that had been carrying more than 250 people. it had been bound for bechar, a town in south—west algeria close to the border with morocco. but shortly after take—off, something caused it to plummet and to crash into a field. translation: we heard a big explosion, and my neighbour and i drove here. there was very heavy smoke, then we realised it was an aeroplane accident. when we arrived at the spot itself, we found piles of bodies. it's a disaster, an absolute disaster. among those who lost their lives were the plane's ten crew. most of the passengers were military personnel. but algeria's defence ministry said some of the soldiers' families had been travelling with them. there have been no reports of any survivors.

algeria's army chief has ordered an urgent investigation to find out what happened, what caused this military plane to crash with such catastrophic consequences. sophie long, bbc news. the uk's biggest supermarket, tesco, has announced a big rise in its full—year profits, reporting a pre—tax profit of £1.3 billion pounds. it says figures have been boosted by the sale of fresh food. the retailer has completed a three—year reform programme, after a series of disappointing results. a memorial service has taken place in south africa for the anti—apartheid campaigner winnie mandela, who died earlier this month at the age of 81. the service, which was open to all south africans, attracted thousands of people to orlando stadium in soweto. winnie mandela was one of the leaders in the fight against white minority rule, when her husband nelson mandela was in prison. a state funeral will be held on saturday. now on bbc news it's time for newsnight with evan davies.

1989. the berlin wall came down, the eastern bloc collapsed, the cold war ended. russia and the world were meant to live in peace. today, with one tweet — "get ready russia, because the missiles will be coming," president trump buried any last doubt. a new cold war has descended. whether it's the skripals, election meddling or events in syria — relations with russia are at centre of a lot going on in the world. we'll look at how this is playing out in regard to syria. as american warships steam towards the mediterranean, we'll assess the possibility of confrontation with russia in syria. and we'll examine what might be happening. what we're really talking about is a patchwork of factions with vladimir putin at its centre. the question is, is he always in control? one of mr putin's old associates

is with us, to explain what's going in the court of the president. also tonight: you can have an anti—abortion vigil, but not at the door of an abortion clinic, according to one london council. is that a restriction that should catch on? and how nineteenth century mathematician ada lovelace was a pioneer of computer science. hello. relations have been getting bad for a while, but we reached a jaw—dropping moment today — a russian ambassador arguing that his country would shoot down missiles aimed at syria, and even retaliate against launch sites if there was an attack. then president trump retorted on twitter, "get ready russia because they'll be coming! nice and new and smart". it sounds rather like the way social

media is said to have amplified gang conflict in london, apparently contributing to the rise in knife attacks. except this is russia and america. it was only back in 2009 that a then new president obama wanted to press the reset button on the relationship with russia. then president trump promised "we're going to have a great relationship with putin and russia." well, not quite. all news leads to russia: the skripals, facebook and fake news, and above all, syria. and it's syria which is forcing a choice on the us and its allies, on how to deal with putin and his. mark urban is with me. mark, on syria, where are we this evening? well we had that tweet this morning, get ready, russia, the missiles on the way. civilian targets, we assume he meant. the white house press briefing this evening, doubt has been cast the president is still looking at options,
