But I found this on BBC:
Hamish de Bretton-Gordon, a former commanding officer of the British Armed Forces Joint Chemical Biological Radiological Nuclear (CBRN) Regiment, said Russia's assertion that the strikes had hit rebel chemical weapons were "pretty fanciful".
"Axiomatically, if you blow up Sarin, you destroy it," he told the BBC.
Experts say the explosion resulting from an air strike on a chemical weapons facility would most likely incinerate any agents. Sarin and other nerve agents are also usually stocked in a "binary manner", which means they are kept as two distinct chemical precursors that are combined just before use, either manually or automatically inside a weapon when launched.
"It's very clear it's a Sarin attack," Mr de Bretton-Gordon added. "The view that it's an al-Qaeda or rebel stockpile of Sarin that's been blown up in an explosion, I think is completely unsustainable and completely untrue."
