Dead at 64, Hezbollah leader Hassan Nasrallah lived a clandestine life on the run

Hezbollah leader Hassan Nasrallah was killed in an Israeli strike on Friday, the Israeli military said, while a source close to Hezbollah said that the Lebanese group had "lost contact" with Nasrallah since Friday evening without confirming his death. Nasrallah was largely responsible for expanding Hezbollah, or Party of God, from a guerrilla faction into Lebanon's most powerful political force.
