The Russian Center for Syrian Reconciliation says the "fake footage of chemical attacks" is expected to be delivered to various TV channels and Western journalists before the end of the day Tuesday.
Russia's Sputnik News indicates based on official Moscow sources:
According to the information received from inhabitants of Idlib province, militants are now filming a staged provocation in the city of Jisr al-Shugur, where "chemical weapons" are depicted as being used by the Syrian army against civilians. The film crews of several Middle Eastern TV channels arrived in Jisr al-Shugur in the morning, as well as the regional affiliate of one of the main American television news networks", the Reconciliation Center said.
Jisr al-Shugur is a key al-Qaeda held town in Idlib Province, specifically under the control of Hayat Tahrir al-Sham (formerly Nusrah Front, or al-Qaeda). There have been international journalists inside Jisr al-Shugur over the past weeks.
