One woman recounted how she was given white burial shroud to wrap herself up in and then told to lay on the ground and smear her mouth with toothpaste,

The reports about the attack and the publication of the footage by the White Helmets prompted missile strikes by France, the United Kingdom and the United States on alleged chemical weapons production facilities in Damascus.

At least 40 members of the White Helmets organization have admitted during recent interviews that they staged chemical attacks in Syria to provoke retaliation against President Bashar Assad, Foundation for the Study of Democracy Director Maxim Grigoriev said on Thursday as he unveiled the results of a new study at the UN.Grigoriev said.The foundation conducted a fact-finding mission in Syria and located both White Helmets members and dozens of other people who participated in the staged attacks, Grigoriev said."Those people told us in detail how they had to participate in the staging for few dollars to buy some food for their families," he said.Grigoriev said.Another recalled being told to "close his eyes" as he was filmed being taken to a medical center by members of the White Helmets.Grigoriev said.A White Helmets member in Douma told the investigators that local children were given candies as rewards for their participation in the staged videos.The OPCW's conclusions relied on falsified facts and untrustworthy or unidentified sources, he noted.In March, the OPCW issued its final report on the investigation regarding the incident of alleged use of toxic chemicals as a weapon in Duma, Syria, in April 2018, which identified chlorine as "most likely" chemical agent used in the attack.Grigoriev said.The Foundation for the Study of Democracy interviewed 15 witnesses at the site of the Douma attack, 40 members of the White Helmets who admitted faking attacks, and more than 25 others who saw the White Helmets stage the attacks. It also analyzed photographs and videos of the incident.The White Helmets, also known as Syria Civil Defence (SCD), operates in parts of rebel-controlled Syria and Turkey and claims to be a group of volunteer rescue workers.The Syrian and Russian governments have accused the White Helmets of staging several provocations involving chemical weapons to justify potential foreign interventions and the presence of foreign forces in Syria, as well as carry arms and support terrorist groups.The OPCW investigation was launched after the White Helmets group published a video of the reported attack in Douma, which is located in the Damascus neighborhood of Eastern Ghouta. The video showed local residents, both adults and children, being treated in the hospital after the alleged attack.The Russian Foreign Ministry has said that the claims about the alleged use of toxic chemicals by the Syrian government were aimed at justifying external military action.
