In November 2019, WikiLeaks released an email from an unnamed investigator from the Organisation for the Prohibition of Chemical Weapons (OPCW) team investigating the 2018 chemical attack in Douma (Syria). The investigator accused the OPCW of covering up discrepancies. Robert Fisk said that documents released by WikiLeaks indicated that the OPCW "suppressed or failed to publish, or simply preferred to ignore, the conclusions of up to 20 other members of its staff who became so upset at what they regarded as the misleading conclusions of the final report that they officially sought to have it changed in order to represent the truth". The head of OPCW, Fernando Arias, described the leak as containing "subjective views" and stood by the original conclusions.
