OPCW ordered to pay damages for smearing whistleblower who revealed Douma false flag chemical attack

However, an engineering report conducted by the mission and a toxicology report commissioned from experts in Germany showed that the victims could not have been killed by chlorine gas and that the yellow cylinders that allegedly were dropped by helicopter to deliver the gas were likely placed on the roof and on the bed by hand.

In other words, the engineering and toxicology reports provided evidence that the chemical attack may have been staged by activists linked to the western-backed armed groups fighting the Syrian government and that the 43 victims had been killed in another way, such as by the activists and militants involved in staging the attack.
