"U.S. and Iraqi officials said U.S. special forces captured the head of the ISIS unit trying to develop chemical weapons in a raid last month in northern Iraq.
The U.S.-led coalition said the chemicals ISIS has so far used include chlorine and a low-grade sulfur mustard which is not very potent. "It's a legitimate threat. It's not a high threat. We're not, frankly, losing too much sleep over it," U.S. Army Col. Steve Warren told reporters Friday.
The coalition began targeting ISIS' chemical weapons infrastructure with airstrikes and special operations raids two months ago, Iraqi intelligence officials and a Western security official in Baghdad told the AP.
Airstrikes are targeting laboratories and equipment, and further special forces raids targeting chemical weapons experts are planned, the officials said. "
So.... IS has and is using chlorine and mustard gas in Iraq. Well ... pilgrims, if you can make those chemical agents, you can make Sarin nerve gas like the weapon used by someone at Ghouta in the east Damascus suburbs in 2013. At the time one of the arguments voiced for assignment of guilt in the Ghouta attack was that the insurgents could not possibly have such weapons because they lacked the ability to manufacture them. As I wrote at the time it is not very difficult to make such chemical weapons. The industrial processes are simple and the ingredients are widely available on the international markets for the making of such things as insecticides. IS is not Nusra or some of the other jihadi groups who were at Damascus in 2013 but the implication for what may have happened at Ghouta should be clear. pl
