U.S. and Israeli officials have long accused Mughniyeh of being directly and personally involved in terrorist attacks which has resulted in many suicide bombings , murders , kidnappings , and assassinations . It began with the Beirut barracks bombing and US embassy bombings , both of which took place in 1983 and killed over 350 , as well as the kidnapping of dozens of foreigners in Lebanon in the 1980s . He was indicted in Argentina for his alleged role in the 1992 Israeli embassy attack in Buenos Aires . The highest-profile attacks for which it is claimed he is responsible took place in the early 1980s , shortly after the founding of Hezbollah , when Mughniyah was in his early twenties . U.S. intelligence officials have accused him of killing more United States citizens than any other man prior to the September 11 attacks , and the bombings and kidnappings he is alleged to have organized are credited with all but eliminating and completely removing the US military presence in Lebanon in the 1980s
