The Syrian Government continues presenting evidence showing that armed opposition groups use chemical weapons, as it seeks to dismantle a media campaign aimed at unleashing a military invasion.

During a raid on Saturday in a warehouse that belonged to mercenaries in Jobar, the Syrian Arab Army found some barrels containing toxic substances made in Saudi Arabia, in addition to some gas masks and pills to neutralize the effects caused by exposure to such chemicals, local television reported.

During the raid, Syrian soldiers suffered from respiratory problems, throat and eye burning and irritation, dilated pupils, weak pulse, muscular contractions, since extremists had sprayed gases to prevent them from occupying the warehouse.

According to medical sources, such symptoms appear when chemical substances or Sarin gas are inhaled.

An official with the Ministry of Defense, who preferred to remain anonymous, told Prensa Latina that a colonel was killed during the attack, and 50 soldiers were hospitalized, some of them with serious conditions.

A commander in Jobar noted that a stash with explosive devices of up to 300 kilograms was found, as well as raw materials to make bombs, plus grenades, RPG and mortar projectiles and remote controls to activate the explosives.
