Recurring pro-Kremlin narrative seeking to absolve the Assad regime of responsibility for chemical attacks perpetrated in the course of the Syrian civil war, as well as to undermine the credibility and independence of the OPCW. They claim that the Douma chemical attacks were staged by Western actors in order to justify military action against the Assad regime.
The internal OPCW e-mail message published by Wikileaks sent on 22 June 2018 by an unidentified member of OPCW’s Fact-Finding Mission (FFM), does not accuse the OPCW management of deliberately manipulating and suppressing evidence gathered by the FFM in order to blame the Assad government for the Douma attack and to justify Western military intervention against Syria.
For example, the management's draft said that chlorine or another reactive chlorine-containing chemical was "likely" to have been released from two cylinders found at the scene. The email argues, instead, that while the cylinders might have been the sources of the suspected chemical there was "insufficient evidence to affirm this".
The e-mail message actually refers to a draft OPCW interim report, not to the final report published in March 2019. The interim report published in July 2018 was basically a progress report which described the FFM’s activities until that date. The final OPCW report accepts the points made by the FFM member in the internal e-mail.
OPCW’s director Fernando Arias stated that the organisation stands by the final findings published in a March 2019 report. “While some of these diverging views continue to circulate in certain public discussion forums, I would like to reiterate that I stand by the independent, professional conclusions,” Arias mentioned.
