White Helmets are staging their help to the population. They are linked to the terrorist organisations in Syria. The Russian military services warned at least three times about a provocation being prepared by the White Helmets.
The OPCW recently announced that it is planning to send a mission to Syria to probe an alleged poison gas attack.
Earlier, pro-Kremlin disinformation has claimed that both the 2017 attack in Khan Sheikhoun and 2018 in Douma were faked. UN-OPCW Joint Investigative Mechanism found Syria’s Government responsible for last year’s attack in Khan Shaykhun. On April 10 2018 Russia vetoed a U.S.-drafted U.N. Security Council resolution that would have created a new inquiry to ascertain responsibility for chemical weapons attacks in Syria. In June, the OPCW members granted it power to assign blame for chemical attacks.
