GENEVA (Dispatches) -- A UN special rapporteur on Saturday again lashed out at the United States for breaching international law by assassinating top Iranian commander General Qassem Soleimani in a drone attack, warning about the repercussions of unbridled and self-willed use of armed drones. "International law is international. It is not American,” Agnes Callamard, UN special rapporteur on extrajudicial, summary or arbitrary executions, tweeted. She added that her warnings on the "exponential, unregulated use of armed drones,” her assessment of the drone strike against General Soleimani and her calls for actions to prevent further crises are all based on international law.
