UN Investigator: Drone Killing of Top Iranian General Unlawful Lisa Schlein GENEVA - A U.S. drone strike that killed Iran's top general, Qassem Soleimani, at Baghdad International Airport in January is a violation under international law, according to U.N. report Thursday. Investigator Agnes Callamard said more than 100 nations have an active military drone inventory and about a dozen allegedly have deployed armed drones for the use of force, such as targeted killings. The uncontrolled proliferation of armed drones poses a threat to international peace, she added, and the U.S. killing of Soleimani has elevated the dangers. She noted the U.S. carried out its attack without first obtaining Iraq's consent, thereby violating Iraq's territorial integrity. .
