Ibrahim Aqil, a senior Hezbollah commander, was killed in an Israeli airstrike on Beirut on Friday. Aqil, who led Hezbollah's elite Radwan Force, had a $7 million US bounty for his role in the 1983 bombings of the US Embassy and Marine barracks in Beirut. He was also involved in the kidnapping of American and European hostages in the 1980s.
