Violence at a soccer match triggered intensified political protests in Egypt raging now into their fifth day. A match on February 1, 2012 in Port Said, Egypt between rival clubs Al-Masry of Port Said and visiting Al-Ahly of Cairo ended with home supporters charging onto the pitch and chasing visiting fans. That confrontation turned bloody when the visiting fans were unable to get out of the stadium, and 74 died from attacks and from injuries sustained in a panicked stampede. Al-Ahly's fans had played a prominent role in defending protests in Cairo's Tahrir Square that eventually toppled leader Hosni Mubarak, and for this reason opponents of Egypt's military rulers assert that police at the stadium allowed the violence to happen, or even encouraged it. Protests continue to grow over the lack of police protection for the fans after three official days of mourning for the victims. Gathered here are photographs of the initial confrontation between fans and the resulting protests from the past several days. -- Lane Turner ( 25 photos total
