MOSUL, Iraq -- An Iraqi officer says Iraqi forces discovered sulfur mustard, a chemical warfare agent, in Mosul alongside a cache of Russian surface-to-surface missiles.
Iraqi special forces Brig. Gen. Haider Fadhil said French officials tested the chemical agent this week and confirmed it was sulfur mustard.
Iraqi forces showed journalists a tank of the chemical agent and a warehouse of more than a dozen surface-to-surface rockets bearing Russian inscriptions in eastern Mosul.
Fadhil said the types of rockets found lead him to suspect the Islamic State group was experimenting with the rockets to develop a way to weaponize the chemical agent.
Iraqi and US officials have repeatedly warned of IS efforts to develop chemical weapons. The extremist group has launched attacks using low-grade chemical weapons in Iraq, causing a handful of casualties.
