And yes, the Syrian regime has used them.
These weapons were in fact moved out of Iraq, the cover-up and deception involved Iraqi, Syrian and Russian cooperation. The long convoys spotted by satellite images moving from Iraq into Syria on the eve of the US attack, is not disputed.
Retired U.S. Army Maj. Gen. Paul Vallely says he has confirmation that Syrian forces have used chemical weapons against rebel forces and civilians, and those weapons are likely stockpiles received from Iraq prior to the U.S.-led invasion 10 years ago.
Vallely has met twice in the region with military commanders for the Free Syrian Army, which he describes as the largest and much more moderate faction among the rebels, which also include elements of al-Qaida and the Muslim Brotherhood. He also gets regular reports from a Canadian medical team. Vallely told WND that team is certain that a chlorine gas weapon was used in recent strikes.
“From what I received from the Canadian medical team who works out of Aleppo is that is was chlorine and that what you saw were the reactions on those videos that were put out within the last week,” Vallely said. “The chlorine, the choking, the skin, depending on the density of the chlorine will cause skin irritation. If it’s mixed with other types of gases too, then it could have an even more enhanced effect on the human body, not only breathing but on the skin.”
