AMSTERDAM, Feb 6 (Reuters) - An investigation commissioned by the global chemical weapons watchdog has found that two former employees leaked confidential information, it said on Thursday, a breach which fuelled a Russian-backed theory that a deadly attack in Syria was staged.
More than 40 people were killed on April 7, 2018, in the town of Douma on the outskirts of Damascus that was then held by rebels but besieged by pro-government forces.
The attack triggered missile strikes by the United States, Britain and France a week later against Syrian government targets, the biggest Western military action against the Damascus authorities during the nine-year-old war.
Douma has been the source of deep division among member countries of the Organisation for the Prohibition of Chemical Weapons (OPCW), with Western powers and Russia locked in political wrangling.
The government of Syrian President Bashar al-Assad and its military backer Russia deny using chemical weapons and accuse insurgents of staging the attack to implicate Syrian forces.
The “deliberate and premeditated breaches of confidentiality ... are considered to be serious,” said an OPCW statement setting out the results of the investigation, which it said was carried out by “independent, professional investigators, from outside the organisation”.
The OPCW did not name the two individuals.
The two, hailed as whistle-blowers by Russian and Syrian supporters, declined to take part in the OPCW-commissioned inquiry, the agency said. The study was based on interviews with 29 witnesses between July 2019 and February 2020.
Amid months of criticism, the OPCW has consistently stood by its findings in a March 1, 2019, report that a banned toxic chemical containing chlorine was likely used in Douma.
The Fact-Finding Mission that produced the 2019 report had not been mandated to identify perpetrators, which is the task of an ongoing study by a newly-formed OPCW team.
The OPCW asked outside experts to investigate how a document written by a former weapons inspector ended up on several websites last May. The inspector, who helped the OPCW team collect samples on a visit to Douma, wrote that two cylinders found at the scene were most likely placed there rather than being dropped from the air.
OPCW chief Fernando Arias told OPCW states in comments published on Thursday that the two individuals are “not whistle-blowers. They are individuals who could not accept that their views were not backed by evidence.”
Arias added that most of the analytical work on Douma took place after they had already left the agency.
A joint United Nations-OPCW mission has concluded in a series of reports that Syrian government forces used banned sarin nerve gas and chlorine in the civil war, while Islamic State insurgents carried out an attack with mustard gas. (Reporting by Anthony Deutsch)
