Whose Sarin?

“The Hersh story belies common sense and suggests that Turkey was able to manufacture a ton of sarin - no easy feat - and then smuggle that sarin into Syria,” Aaron Stein, an Associate Fellow at RUSI and the nonproliferation program manager at the Center for Economics and Foreign Policy Studies in Istanbul, told Islamist Gate.
“That Sarin is then loaded into volcano rockets that were fired from government controlled areas towards rebel positions. As Dan Kaszeta [security and CBRN specialist] has pointed out, there are close correlations in chemistry (such as hexamine, a possible sarin additive) between the trace evidence found in the field and the inventories disclosed by the OPCW [the Organisation for the Prohibition of Chemical Weapons]".
Stein added that therefore “Hersh’s article is at odds with science and common sense and suggests a deeper misunderstanding of Ankara’s Syria policy.”
