Oh, right..next you'll be claiming the UK etc did the original chemical attack in Douma.
(Lavrov??? This is the bloke who says the UK is trying to destroy the Skripal evidence..?? Having sent samples to 5 OPCW labs..?? And btw all that Lavrov claimed so far is that there were TRACES of BZ. what's a trace? ...1ppm ?? )
Until the Swiss lab speaks publicly in detail, it's a case of "Really Sergey?"
