this is the w.'s live from berlin a british military lab says it cannot prove the nerve agent used to attack former double agent screwball and his daughter came from our shop on that undermines the u.k. foreign minister who told the view news last month the evidence was in this beautiful they were upset because a girl called my office to go first so i said are you sure and he said that in the dark. so as an international watchdog meets to discuss the attack we ask how certain we can be about the origin of the chemical weapons also coming up drawing

up a blueprint for post-war syria turkey russia and iran discussed the war torn countries future and tips for attached china slaps punitive measures on more than one hundred american products including soybeans and cars is beijing's looking answer in kind after the u.s. government imposed tariffs on chinese imports the trade spat between the economic superpowers is escalating stupid markets. thanks very much for your company everyone the global chemical weapons watchdog is holding a special meeting to discuss the poison attack on a former russian double agents in britain moscow has demanded a joint investigation into the attack a move britain has denounced as quote perverse smile in an interview with you that we use isn't and so in them so. british foreign secretary boris johnson said there

was no doubt in his mind that russia is to blame you argue that their source of north edge and novacek is russia how did you manage to find that out so quickly that was driven by says samples of the case when i look at the the evidence we the people from porton down the the border they have the samples you do and they they they were absolutely categorical and i asked the guy was so i said are you sure and he said they don't now and so there is little doubt in boris johnson's mind about the provenance of the nerve agent but chemical weapons experts have failed to back up the foreign secretaries assertions and that is complicated an already murky situation this is porton down the lab in britain at the center of the investigation into the poisoning of the screen. despite the british

government's confidence the head of the lab says they cannot confirm the nerve agents origin it's our job to provide eight you know the scientific evidence that identifies court the particular narrow feature is what identify that it was from this family and that is military could eat their feature but it's not our job to see where actually was money for the russians meanwhile called for a meeting of the organization for the prohibition of chemical weapons in the hague to address the u.k.'s accusations moscow continues to deny involvement and has claimed officials in the west may have staged the poisoning. got this meat even in the script case of a grotesque provocation crudely can cut to by u.s. and british security services some european governments are not following london and washington blindly. but instead choosing to carefully make sense of what happened. it was about solutions germany is not one of

those european governments they are standing by britain's version of events or analysis remains the same great britain is explain to us in great detail why russia's responsibility is very probable and why there is no plausible alternative explanation and we agree with great britain's assessment yulia is now reported to be recovering from the attack sergei her father is still in critical condition and relations between the west and russia are now at their lowest point since the cold war. and a key logan is in london for us to talk about awkward how are british authorities dealing with these discrepancies yes this comes at a pretty bad time the u.k. government which is already under pressure about the missiles brain incidents the government has been out today trying to explain the context of these comments

explained hold down is simply a lab where the scientists made the evaluation that this was not a top of agent that it did was originally produced in russia where they didn't say the precise source was russia but unfortunately or as johnson as we've heard there has been on the record in the past saying exactly that and there was also a foreign office tweet which indicated the sane porton down had said that the agency came from the net as you can from russia a foreign office has since delete it is tweet or what is will leave us that you've publicly confused that's the sure it also plays into russia's hands because what has been all along that there was no clear evidence that innovation didn't come from russia right and russia didn't skip a beat seized on the fightings of findings of this report demanded a still to mount an apology in the meantime got the o.p.c. w the global chemical weapons watch talk to grant its request for an emergency meeting what's at stake here kitty for the u k. that's why then notice the meeting

taking place in the hague behind closed doors already u.k. and russia are all of russia wants a joint investigation the u.k. says no way on they say they absolutely would not allow it and the u.k. is standing by its position it says the evidence is too overwhelming and it's interesting to see that the e.u. and other countries other international countries are still standing by the u.k. so if you the british government is pretty confident that there is an art information and evidence out there to back its claims or minus again kitty what is the government's evidence that establishes a clear link to moscow and why don't they just make it public. this is the big question and this is what a lot of people are asking now asking for more detail the government says it's not just about what the scientists at porton down lab continued it's it's also about intelligence sources it's about historical context for example the latino vote it's about the police and expressed

a geisha which is extremely detailed and of course ongoing still it's as if all it if have compiled a bigger picture showing that base must have come from russia is never agents it says that this knowledge help was originally produced in russia it was stockpiled in russia it says there is simply no other explanation as to where it came from but as a concrete evidence that they're holding back on it maybe it's because they want to protect their intelligence or sources but the problem is that it's still adding to the conspiracy there is the confusion and it's adding weight to russia's argument could be logan reporting from london thank you. want to tell you now about some of the other stories making news around the world. a woman in what has shot and injured three people at the you tube headquarters in northern california before fatally shooting herself police have identified the suspect as in a scene of activists blogger who accused you tube of censoring her videos where he say they are still investigating a motive. a dutch lawyer with russian ties has become the first person to be

sentenced in the u.s. special council's russia probe alexandre serrano was handed a thirty day jail term and ordered to pay a twenty thousand dollars fine he admitted lying to robert muller's investigators about his contacts with an official in donald trump's campaign. italy's president said you must not allow has launched formal consultations aimed at creating a coalition government after last month's inconclusive elections the populist five star movement emerged as the largest single party while an alliance of center right and far right parties took the most seats neither group gained enough votes to govern alone. the leaders of iran turkey and russia have met for a summit on finding a political solution to the syria conflict presidents are rich of type one hosted russian leader vladimir putin and iranian counterpart hasn't met rouhani for talks

in the turkish capital. the three nations have emerged as the power brokers of syria's nearly a year long protracted civil war in addition to peace they're looking to bolster their influence in the country all three nations have large but also competing interests in the outcome of the syria conflict. you know we use the dorian jones is an encore covering the trial lateral summit dorian fill us in what's come out of this meeting. well the message coming from the three leaders even though they're all opposing sides in the syrian civil war is a corporation who works with. corporation will continue to deepen the claim that success in the creation of these deep conflict zones in syria which is where syrian rebels and their families are being slowly moved to they say that this has been successful and it will continue throughout syria they also said that this will revive serviceability in the country and will allow the return of syrian refugees

are not a priority the leaders say is out of this meeting and that will be particularly welcomed by turkey which hosts around three million syrian refugees and there is specially growing unease among the turkish public over that presence beyond that there was a message to the u.s. they say made it clear that they don't believe the u.s. should be involved in syria they said they don't want foreign powers interfering in syria they play much of a conflict on that interference that is a thinly veiled reference to the u.s. and opel so a warning to turkey a serious large kurdish minority because with them saying that they are all the leaders are committed to the syria's territorial integrity every sphere that because the syrian kurdish militia controlling a third of syria they could ultimately secede from the country all leaders have commit themselves to prevent our right well i want to pick up on that point so the three leaders asserting their support for syria sovereignty territorial integrity as you've just been reporting and the right of the syrian people to shape their own future yet these are three major stakeholders with boots on the ground planes in

the air vying for influence in syria how do they square that circle. well known confronted them on that at the press conference and all the questions came from carefully selected journalists from their countries but yes you're right there does appear to be a great deal of hypocrisy there but the fact is increasingly describing themselves as a government to move to syria and that is a common statement coming from all of the leaders they believe because they have invested a large amount of treasure and soldiers on the ground and that they have these direct links to syria they claim that allows them to take this role and at the end of the day they say they believe because they are the main players they are involved in backing the key parties in this only they can bring peace and a solution to syria all right you referenced in your previous answer the role of the u.s. which has been condemned by these three leaders president trump was not part of this summit in ankara he made that surprise announcement yesterday that he wants

any u.s. involvement to be diminished in syria has there been any reaction to that surprise announcement. one of the iranian president hassan rouhani malk the united states saying that they keep changing their minds over syria in a fight i was alluding to the point of despite comments of wanting to withdraw from syria there are polls of the pentagon are increasing their military presence in syria backing a syrian kurdish militia but ultimately there is growing alliance between these tea parties is deemed aimed at pushing america out of syria and not ultimately will be a major headache to washington and possibly brings a looming confrontation between american backed syrian kurdish militia and turkish military forces with the turkish president vowing to remove them all from syria dorian jones reporting from ankara on that trilateral summit thank you. and staying with president trying to tweet of the day comes from who else but mr

trump himself it reads we are not in a trade war with china and funnily enough the year two economic superpowers are locked in a tent for tat clash not a day goes by now without one side upping the stakes this time especially. china has launched rockets and built high speed trains the chinese economy has been booming so much that it can counter the u.s. threat of punitive tariffs china is not about to take the trade dispute with the us lying down we will take corresponding measures of equal intensity against u.s. products according to chinese foreign trade laws which will be announced in the near future we have the confidence and ability to respond to any protectionist measures. the tit for tat is now in full effect beijing plans to match washington's fifty billion dollars in tariffs with tariffs of its own and the u.s. move disregards the nature of mutual benefit in economic and trade cooperation it

disregards the two countries industries and the interests of consumers and is neither conducive to chinese new american national interests e.g. . more than one hundred u.s. goods are affected by the terrorists they include soybeans cars and beef that will make those products more expensive for chinese consumers for american producers it will mean fewer exports to china a major market the trade dispute has now entered the next phase. all right and before i let you go and remind you of our main headlines this hour. britain has dismissed an appeal from russia to join its investigation into the poisoning of a double agent and his daughter and salisbury chemical weapons experts have failed to back claims by the british government that the nerve agent used in the attack came from russia. the leaders of turkey iran and russia say it's important to prepare the ground for the return of syrians displaced by
