“In the past, ISIL has used drones in Iraq and Syria for general intelligence-gathering, as spotters for mortar firing, and even for filming propaganda videos. Soldiers have regularly spotted these drones over army positions on the outskirts of Mosul, prompting bursts of gunfire skywards. But there is a fresh threat, Saadi said: ISIL has begun to use the drones themselves as weapons. ‘They also use a new tactic, where the drone itself has a bomb attached to it,’ he explained.”
