In 2005 ten captured Al-Qaida terrorists stood trial in Jordan for attempting to explode roughly 20 tons of chemical weapons. Authorities captured the weapons coming into Jordan through Syria. It was the largest WMD cache ever captured for a planned massacre.
In September the Obama Administration admitted that the US had lost track of some of Syria’s chemical weapons. Secretary of Defense Leon Panetta told reporters that they are not sure if the opposition obtained the WMD or how much they may have obtained.
