The Kremlin commented on the claims and said that it considers US' threats against Syrian legitimate leadership to be "unacceptable." Damascus also denied the information.
"In any case, it is Washington that looks very unsavory in this story: they either know about the upcoming attack and are not trying to prevent it, but knowingly put the uncomfortable Syrian leader in the wrong for that… Or the United States is preparing its own preemptive strike on Syrian troops and appeals to the topic that is already ‘famous’ on a global level and will definitely justify any preventive action," the chairman of the upper house of the Russian parliament's international affairs committee said, commenting on the statement of the White House.
Damascus has repeatedly denied any involvement in the incident and said that the Syrian government doesn't possess chemical weapons as the full destruction of Damascus’ chemical weapons stockpile had been confirmed by the Organization for the Prohibition of Chemical Weapons (OPCW) in January 2016.
In an interview with Sputnik on April 21, Assad characterized the alleged chemical attack in Khan Sheikhoun as a provocation to justify the US strike on Ash Sha’irat. The Syrian leader also warned of the possibility of the new provocations similar to the one in Khan Sheikhoun.
