Pakistani police opened fire on rioters who were torching a cinema during a protest against an anti-Islam film Friday, and security forces clashed with demonstrators in several other cities in Pakistan on a holiday declared by the government so people could rally against the video. Thousands of people protested in several other countries, some of them burning American flags and effigies of President Barack Obama. (AP Photo/B.K. Bangash)
