BEIRUT -- Hezbollah's leader has made a rare public appearance at a rally in Beirut denouncing an anti-Islam film that has provoked a week of unrest in Muslim countries worldwide.

Hassan Nasrallah does not usually appear in public for fear of assassination. He called for Monday's protests in Beirut, saying the U.S. must be held accountable for the film because it was produced in America.

He is speaking to a crowd of tens of thousands of supporters.
