Tens of thousands of Bahraini anti-government protesters march Friday, March 4, 2011, from the main government house in the capital of Manama, Bahrain, to the Pearl roundabout, where they have set up camp. Also on Friday, thousands of anti-government demonstrators streamed toward headquarters of Bahrain's state television hours after sectarian clashes between Sunnis and the majority Shiites who are leading protests in the strategic Gulf nation.
