Iran is pointed out by Israel and western allies as responsible for the July 29 attack on a ship with Israeli ties off the coast of Oman. The attack on the oil tanker Mercer Street killed two foreign crewmen, a British citizen and a Romanian citizen. The vessel is partially owned by a company belonging to an Israeli businessman.

The use of suicide drones by Iran is not new. In January Iran’s paramilitary Revolutionary Guard conducted a drill that saw suicide drones crash into targets and explode.

Bomb-carrying drones are sometimes referred to as “loitering munitions.” The drone flies to a destination, likely programmed before its flight, and either explodes in the air over the target or on impact against it.
