ISIL recently has used devices filled with chemical agents against Kurdish forces and civilians in both Iraq and Syria, a joint investigation by two independent organizations has found. The findings build on previous reporting that ISIL (the Islamic State in Iraq and the Levant) has begun to adapt both suicide bombs and improvised explosive devices (IEDs) to include chlorine and other chemicals and may seek to exploit the use of chemicals as it develops new weapons, CNN reported. The two U.K.-based groups -- Conflict Armament Research (CAR) and Sahan Research -- sent teams to investigate allegations that ISIL used chemical munitions on three occasions last month. Two of the incidents occurred in Hasakah province in northern Syria, where ISIL is locked in battle with the Kurdish YPG group. The third involved a 120 mm mortar that landed near Kurdish positions at the Mosul Dam in northern Iraq but failed to explode. CAR said this was "the first documented use by (ISIL) forces of projectile-delivered chemical agents against Kurdish forces and civilian targets."
