The "Report on the Alleged Use of Chemical Weapons in the Ghouta Area of Damascus on 21 August 2013" concludes that "chemical weapons were used on a relatively large scale, resulting in numerous casualties, particularly among civilians and including many children." On December 12, 2013, the final report on the investigation was released.

109. The United Nations Mission collected clear and convincing evid ence that chemical weapons were used also against civilians, including children, on a relatively large scale in the Ghouta area of Damascus on 21 August 2013.

  • Impacted and exploded surface-to-surface ro ckets, capable to carry a chemical payload, were found to contain Sarin;
  • Close to the rocket impact sites, in the area where patients were affected, the environment was found to be contaminated by Sarin;
  • The epidemiology of over fifty interviews given by survivors and health care workers provided ample corroboration of the medical and scientific results;
  • A number of patients/survi vors were clearly diagnosed as intoxicated by an organophosphorous compound;
  • Blood and urine samples from the same patients were found positive for Sarin and Sarin signature.
