The intentional and pre-meditated use of lethal force, by a State or organized armed group  against a specific individual outside their physical custody. Targeted killings occur both within and outside of armed conflicts. Under IHL, they are problematic as, oftentimes, those targeted are geographically far removed from hostilities, and/or not necessarily directly participating in hostilities at the time they are targeted. In the context of the war on terror, targeted killings against suspected terrorists, including “unlawful combatants”, have occurred regularly. Drones are frequently relied on to undertake such killings.
