A supporter of Lebanon's Hezbollah group holds pictures of Hezbollah chief Hassan Nasrallah (L), Syrian President Bashar al-Assad (R) and slain Hezbollah commander Imad Mughnieh (bottom-C) during a rally in southern Beirut to denounce a film mocking Islam on September 17, 2012. Hezbollah chief Hassan Nasrallah, who made a rare public appearance at the rally, has called for a week of protests across the country over the low-budget, US-made film, describing it as the "worst attack ever on Islam."
