Kenyan riot police stand guard as supporters of the opposition for the Orange Democratic Movement (ODM) protest in the streets of the capital Nairobi March 7, 2006. Thousands of Kenyan opposition demonstrators took to the streets in Nairobi on Tuesday to protest against an unprecedented police raid on a major media group last week and call for the government's ouster. Brandishing banners, about 2,000 protesters called for the resignations of President Mwai Kibaki and Internal Security Minister John Michuki, who defended the raid saying it was a matter of state security.
