The news outlet claimed that the files on reported cooperation was leaked to it along with thousands of documents identifying 22,000 Daesh supporters in more than 50 countries, which were handed over by former Free Syrian Army converts to the terrorist group in March.
According to the leaked documents, the authenticity of which "is impossible to verify," control under the recently liberated ancient Syrian city of Palmyra was returned to government forces by the Daesh as part of a series of cooperation agreements.
The British channel claims, citing secret unverified data, that other deals between Damascus and the extremists included the reported trade of oil for fertilizer, as well as the alleged evacuation of some areas controlled by the Daesh before the Syrian army attacked.
The Sky News claimed that all previous materials on the Daesh leaked to the media outlet have proved to be genuine.
According to the newly obtained data, the jihadist group has been training foreign militants to carry out attacks in Western cities for a much longer period of time than known by security services.
Damascus has not yet made any official statements regarding these allegations.
In April, Syrian Prime Minister Wael Nader Halqi told Sputnik that Saudi Arabia, Qatar, Turkey, France and the United Kingdom were attempting to destroy Syria’s infrastructure and economy, and were arming terrorists in the country to prevent the political settlement of the Syrian crisis.
