Bahrain on Edge
Tens of thousands of Bahraini anti-government protesters converge Friday, March 4, 2011, on the Pearl roundabout in Manama, Bahrain, after marching from the main government house and past the financial district calling for the government to fall. 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.
