BEIRUT (AP) — In a rare public appearance, the leader of the militant Hezbollah group exhorted hundreds of thousands of supporters Monday to keep up the campaign against an anti-Islam video that has unleashed deadly violence and anger at the United States across the Muslim world.

Although the massive, well-organized rally in Beirut was peaceful, protesters in Afghanistan set fires near a U.S. military base, clashed with police in Pakistan, where one demonstrator was killed, and battled with officers outside the U.S. Embassy in Jakarta, Indonesia, the world's most populous Muslim country.

The turmoil surrounding the low-budget video that mocks the Prophet Muhammad showed no sign of ebbing in the week after protesters first swarmed the walls of the U.S. Embassy in Cairo. Four Americans, including the U.S. ambassador to Libya, died amid a demonstration in the eastern Libyan city of Benghazi.
