CAIRO (AP) - Hundreds of Egyptian protesters have marched on a building belonging to the internal security service in Alexandria, and a medic says officers inside fired on the crowd, injuring three demonstrators.
Military forces arrived and dispersed the crowd of around 1,000 people after a tense standoff. The state news agency says protesters set four police cars on fire.
The demonstrators who forced out President Hosni Mubarak last month are demanding that Egypt's State Security Agency be dissolved. Its agents are blamed for some of the worst human rights violations during Mubarak's rule.
The confrontation contrasted with celebrations earlier Friday in Cairo to mark the announcement of a new prime minister.
