The US has claimed that both sarin and chlorine were used by Syria in an attack that killed dozens of civilians in Douma, an attack America, France and Britain said led them to carry out retaliatory air strikes, but which which the Syrian government denies having a role in.
On Friday night, barely an hour after the multi-nation attacks on three Syrian targets allegedly linked to the production, use and storage of chemical weapons were completed, US Defence Secretary Jim Mattis said the US was certain one deadly compound was used and that there may have been more than one. “We are not clear on that yet. We know at least one chemical agent was used,” he said.
Yet on Saturday, an unidentified US official told the media the US had now assessed that sarin and chlorine were used in the attack in the Damascus suburb of Douma.
