Protesters stormed the U.S. consulate and set the building ablaze in Libya Tuesday, killing one American and injuring another. In Cairo, demonstrators took to the U.S. Embassy, tearing down the American flag and replacing it with a black flag emblazoned with Islamic symbols. The demonstrations are thought to be in response to a movie produced in the U.S. that protesters say insults the Prophet Muhammad, though it's not clear yet exactly which film sparked the outrage. American director Sam Bacile has claimed credit, telling reporters, "I am the first one to put on the screen someone who is [portraying] Muhammad. It makes them mad."
