can italian giantsjuventus secure good evening. tensions between the west and russia over an alleged chemical attack near damascus at the weekend have intensified, with president trump warning moscow to get ready for missile strikes against syria. in return, russia has been urging washington not to take military action, and senior figures are

our north america editor jon sopel is at the white house for us tonight. jon? the white house briefing hasjust ended, clive, and not for the first time you had the president's press secretary walking back one of his tweets, while donald trump said the missiles were becoming my sentiments marred, sarah sanders said all options are open and no final decisions have been taken. after that bellicose tweet from the president, one of his allies in the senate, rand paul, said promising war by tweet insults not only the constitution but every soldier who puts their life on the line. 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, we point to declarations made by president 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 are 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 one 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.

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 heard from both sides is, frankly, more akin to two heavyweight boxers trash talking at the way in before a boat. but leaving the words to one side there are wider strategic questions. what is american policy now toward syria? does it support regime change? does it want further involvement or to pull out? we are none the wiser on those questions. jon sopel, bbc news, washington.

our deputy politcal editor jon pienaar is at westminster. this cabinet meeting to be convened at number ten tomorrow carries added significance? yes, senior ministers will meet tomorrow in downing street for the special cabinet meeting and we can expect a formal final decisions there. i think it is already clear tonight that the prime minister is poised to see britain involved in military action. she as good as said so military action. she as good as said so tonight when she spoke about the need to prevent and deter another chemical attack. today the prime minister has worked hard to keep up with donald trump. those tweets landed with quite a third in whitehall. how the —— says it was that parliament will be delicate. labour leaderjeremy corbyn says any military action should require parliamentary approval in advance, but well posted senior sources say the prime minister is perfectly prepared to contemplate taking action and doing so without prior approval. she believes action is

urgently needed to prevent another possible chemical attack. although you would not expected to say this, she is reluctant to as donald trump to hang on while she seeks the approval at westminster. you may think that the prime minister generally as a cautious leader, and she is, but events seem to be moving under their own momentum, and rather quickly. thank you, john pienaar. so what's the reaction in moscow to all this? steve rosenberg is there. what is the latest response from the kremlin? moscow has made its position crystal clear. it has belted out in today's edition of the russian government paper which said that russia reserves the right to shoot down planes and sink ships acting aggressively in syria. that sounds like a direct warning to the united states and allies not to launch a military strike on syria. are the russians bluffing ? military strike on syria. are the russians bluffing? is this simply

bluster, empty sabre rattling? possibly, but to dismiss it as such is very risky. we're talking high—stakes is very risky. we're talking high—sta kes geopolitical poker. russia is a nuclear power which has been pursuing an increasingly aggressive foreign policy, and relations with the west have grown increasingly strained. one more thing i would add, neither moscow nor washington wants the war in syria to move into a war between russia and the united states, but the problem is when you have a surfeit of rhetoric and sabre rattling, as there is on both sides, and you add the deficit of trust, it isa and you add the deficit of trust, it is a very dangerous combination. thank you, steve rosenberg in moscow. our middle east editor jeremy bowen is here. jeremy, looking at the map behind us, we have the us, the uk and france lined up against syria, russia and iran in a region where syria, a country at war for seven years, has neighbours ranging from turkey, israel and lebanon. the stakes are high, but what is your assessment of where this will end?

it is an incredibly high set of sta kes it is an incredibly high set of stakes because, and this is a phrase i have used quite a lot of times of my reporting about this, it has become in the last few years a mini world war in syria. lots of countries involved, different and clashing interests. in such a highly militarised environment the risks of something going wrong, some kind of escalation, will always be there. what the americans, british and french want to try to do, they talked about this a lot at the un yesterday, to stop the normalisation, as they see it, of the use of chemical weapons, to restore deterrence and red lines so people think very hard before they are used. that means they need to work out just what level of are used. that means they need to work outjust what level of response they do, the kind of military operation they might want to embark upon, which does not then set of all

those other risks we saw on the map, which will be the nub of it and will be very difficult. what they have to be very difficult. what they have to be aware of, and i think the military is very aware of, it is not like a video game where you can go effortlessly up to the next level, it is always difficult and dangerous and dirty, especially in a country as militarised as syria. jeremy, many thanks. 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 lawmakers 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, let me 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 the 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 and half billion dollars an hour, not bad when you move to silicon valley. —— 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 giant 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 rather than washington. that should worry zuckerberg most. but he'll sleep easier tonight. amol rajan reporting there. scotland yard says the investigation into the murder of stephen lawrence is unlikely to progress further without new information. the black teenager was stabbed

by a group of white youths in south east london in 1993. two men are serving life sentences for his killing, but there have been no other prosecutions. stephen's father, neville lawrence, told the bbc he would accept the inquiry being scaled back, but believed it should not be completely closed. yulia skripal, who was poisoned by a nerve agent in salisbury in march, 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, is with me now. frank, is it clear that yulia skripal pepped this statement it does seem quite strange? that is the first question i put to government officials in whitehall because of course we have no access, nobody does, to yulia skripal. she is in a secret, secure location. somewhere, presumably a country house, under

police protection. probably armed police protection. probably armed police protection. probably armed police protection. but i've been assured that the decision that is went into the wording of this were 100% went into the wording of this were ioo% hers. they are significant. ‘s absolutely unequivocal in this statement shech says, "i do not wish to be contacted by the media, not by the russian embassy and not by her cousin victoria." that's significant because her cousin victoria is in russia. russia media aired a surprise telephone conversation between the two of them, and it's very significant that she says victoria does not speak for me or for my father. she says she's still recovering. her father for my father. she says she's still recovering. herfather is not for my father. she says she's still recovering. her father is not at all. her life has been turned upside down by this. she hasn't yet decided where she will go from here, but for now she's refused russian consular access. the russian embassy responded saying it's access. the russian embassy responded saying its beginning to look more and more liked a forced detention. the russian embassy does

not accept she is speaking of her own mind and being forced to say this stuff and kept apart. that is not what british government officials are saying. 0k, frank thank you, frank gardner. 200 people on board a military aircraft have died, after the plane crashed in algeria. state television is reporting 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. voters will go to the polls injuly for mexico's presidential elections and one of the key campaign issues is security. for more than a decade, successive governments have been battling powerful drug syndicates, and while there's been some success in capturing or killing cartel leaders, deaths linked to traffiking and organised crime have rocketed in recent years. in 2017 there were close to 30,000 homicides. so far this year there's been

an average of 71 murders every day. cameraman darren conway and i went to the beach resort of acapulco, in guerrero state, one of the worst affected by all the violence. there we talked to paramedics on the front line. a warning, this report contains some distressing and graphic scenes. there's also some flash photography. this is the story of a country at war with itself, and the innocent who are on the front line. for mariella chamayo and her husband jorge, an evening out with their son is a welcome escape from mexico's bullets and brutality. but their work means the violence is never far away. a security camera captures the scene at a convenience store in downtown acapulco. so far, so ordinary. two children are playing on the floor. suddenly a man enters,

pursued by another, who wants to kill him. he's wrestled outside, to the relief of staff. then they dive for cover. he's been shot. imagine the terror of the shop workers as the assassin tries to finish him off. but his pistol jams. reloaded, the gunman returns. he dies 30 minutes later. first on the scene is paramedic mariella chamayo, but unable to save another victim of mexico's gang wars. she's worked acapulco's streets for almost a decade. along with her husband jorge, mariella's on her way

to another gang land hit. we follow behind. shot and dumped, the indignity of it all. and on hand, the military. but seemingly powerless to stop the carnage as drugs and organised crime fuel mexico's brutal gang wars. last year three times as many people were killed in mexico

than in afghanistan, almost 30,000, and already in the first two months of this year there have been 6,612 gang killings. another call‘s come in. another victim awaits. siren the pictures will help in the investigation. but will the killer ever be found?

it's unlikely. it's an ugly scene and the strain of all the killing is beginning to wear mariella down. back at base, a bit of down time, a little lunch and a moment of reflection. but moments of peace are fleeting for those picking up the pieces of mexico's gang violence. a man's been shot in the chest. mariella reaches the scene just after the police arrived. but before she can examine the body, the dead man's family turn up and realise the worst.

aware our cameras are rolling, their grief is profound. another name then to be added to the hundreds killed so far this year in acapulco. nano sanchez, he was 56, dead before mariella had a chance to save him. it's what everyone wants. but ordinary people here, like mariella, feel impotent, overwhelmed. stuck in the middle of a war on drugs that mexico and its politicians seem to be losing. the continuing problems there of mexico's war on drugs. nearly 2,000 jobs are at risk in greater manchester

after the online retailer, shop direct, said it would close three warehouses in the area. the firm which owns the fashion website very, as well as littlewoods, says it's shifting operations to an automated warehouse in the east midlands. a pint of milk delivered to the doorstep was a staple for most families until the 1980s. but after decades of decline, dairies are reporting an increase in glass bottle deliveries. it's all to do with consumers wanting to protect the environment amid greater awareness of plastic waste. our business and consumer correspondent, nina warhurst, has more. all is quiet in the village of marske in redcar. arriving at eileen‘s, ian has the birds and his bottles keeping him company. a milkman for 28 years, ian has witnessed a steady decline in doorstep deliveries. we've seen some redundancies, good friends lost theirjobs, but it seems to be picking up again.

keeping you busy, then? keeping me busy, exactly, yeah. that's good. gladly, yeah. since january, ian's dairy has been delivering 4,000 more glass milk bottles a week. and out of 20 dairies we spoke to, 17 said they'd also seen a rise. this is the first year that we've actually seen an increase in sales and production, and i think it's more on the back of everybody being more aware of the environmental impact that plastics have, as opposed to glass returns. not bad news for you, either. no, definitely not. the morning clink on the doorstep became a post—war staple and by the late ‘70s, 90% of britain's milk was delivered to homes. but despite popular advertising, then came deregulation and the rise of the supermarket, triggering a decline to just 3% of the current market. but it survived. eileen likes knowing that her bottles are reused, and she likes her milkman.

so how long have you known ian? over 12 years. 12 years?! in the winter, it was brilliant. poor ian, i was opening the door and it was deep snow, the bottles were just plonked in. ah, poor soul! a pint of eileen‘s milk costs 65p, so four of them is more than £2.50. but less than half a mile up the road is a major supermarket, where the same volume of milk costs less than half the price, so eileen‘s next door neighbours aren't that keen to convert. living near the sea, jill's been horrified by images of plastic waste, and yet... does that tempt you to move to glass? i'd like to think i would, but, no, iwouldn‘t. it's cheaper, and that's the bottom line. the waste charity wrap told us that because of the environmental impact of cleaning and delivering, a glass bottle must be used 20 times to beat plastic. ian's bottles are used around 50 times, so he's hoping more customers will see them as the green option

for the white stuff. nina warhurst, bbc news, redcar. gillian ayres, one of britain's leading abstract painters of the last 60 years, has died at the age of 88. she was at the forefront of the british contemporary art scene from the 1950s and became known for paintings filled with vibrant shapes and colours. she was nominated for the turner prize in 1989 and 15 of her works are held in the tate modern collection. in tonight's champions league football, real madrid booked their place in the competition's semi—finals in dramatic fashion. commentator: here comes ronaldo. and he scores, of course he scores! the home team needed this cristiano ronaldo penalty —

in injury time — to secure victory. juventus had scored three times to pull the tie level on the night. but with the match heading for extra time, ronaldo's strike finally took real through. scotland has secured it's best ever medal tally at an overseas commonwealth games, reaching 32 so far, on australia's gold coast. in the diving, england's jack law won the one meter springboard, defending the title he won in glasgow four years ago. meanwhile, eight athletes from the cameroon team have gone missing, with organisers saying anyone overstaying their visa will be deported. natalie pirks now reports on a memorable day for scotland's athletes. nestled amongst the ubiquitous aussie yellow, the saltire has been a regular sight on the gold coast. today, some sharp shooting edged scotland ever closer to their games medal target. first, with linda pearson's bronze in the women's double trap. in the men's competition, 21—year—old scot, david mcmath, was showing nerves of steel. commentator: if he hits this pier, he will be the commonwealth games champion.

never in doubt. tim kneale took the silver for the isle of man's first medal of the games, it clearly meant a lot. to kind of wear the three legs of man and to be here representing the island is... yeah, it's something special. special too for scotland, mcmath's gold took them to the magic number of 30 medals. flower of scotland so it's official, these are scotland's greatest ever away games, and a lot of it is down to just one man. duncan scott wrote his name into the record books here, his haul of six is the most medals for a scottish athlete at one games. his gold in the 100 metre freestyle was a particular highlight. i can't really sum it up in words, to be honest. you know, it's pretty special and it's something that i didn't think i'd be able to achieve. yeah, i mean, i don't really know what to say, to be honest. his family did the talking for him, they had to set up crowdfunding to get here.

my mum and dad are out here watching. you know, they've got the biggest banner in the stands. their support out there was amazing. you know, it made the home crowd for the aussies not feel like such a home crowd.
