Imad Mughniyeh was born in 1962 in the Lebanese Shi'ite village of Tayr Dibba to a poor family of olive and lemon harvesters. He moved to Beirut as a child and despite his religious affiliation, he became active in the predominantly Sunni Palestinian al-Fatah movement. In Lebanese Palestinian reports, Mughniyeh was even described as participating in the unit of bodyguards protecting then-PLO chief Yasser Arafat. But after the PLO chairman and his fighters were forced to leave Lebanon following the Israeli invasion in 1982 - just three years after the Islamic Revolution in Iran - Mughniyeh returned to his own religious cohort and joined Hezbollah, "The Party of God," a heavily armed Lebanese faction established and nurtured by Iran.
