He “died in an explosion” which doesn’t tell us much. We’ll probably know more before the day is out:
The FBI listed Imad Mughniyeh as one of its “Most Wanted Terrorists.”
Imad Mughniyeh was suspected by Western intelligence agencies in the 1983 bombing of the U.S. Embassy in Beirut, which killed 63 people, as well as the truck bombing that year of the U.S. Marine barracks there, an attack that killed 241 people and preceded the U.S. military withdrawal from Lebanon, according to a CNN report from 2001.
The FBI listed Mughniyeh as one of its “Most Wanted Terrorists,” blaming him for his role in the June 14, 1985, hijacking of TWA 847, a terrorist episode that captivated television viewers in the United States and around the world for more than two weeks.
Hijackers seized the plane as it traveled from Athens, Greece, to Rome, Italy, and forced it to land at the airport in Beirut, starting a 17-day ordeal during which a U.S. Navy diver, Robert Dean Stethem, was shot and killed.
