Death toll in latest Egypt clashes climbs to 12 CAIRO (AP) - Egyptian security forces on Saturday fired tear gas from armored trucks at protesters demanding an end to military rule, as anger over a deadly soccer riot fueled a third day of clashes that have killed at least 12 people. The violence followed a melee and stampede after a soccer match Wednesday in the Mediterranean city of Port Said in which 74 people died in the world's worst soccer violence in 15 years. Protesters accuse the security forces of failing to prevent the bloodshed. After two days of running street battles, clashes broke out again in downtown Cairo Saturday as protesters marched on the Interior Ministry. Security forces fired volleys of tear gas at rock-throwing protesters calling for the army to relinquish power and the execution of Egypt's military ruler. The ministry has been a frequent target for the protesters because it is responsible for the widely distrusted police. In parliament, lawmakers on the national security committee held an emergency meeting to discuss the latest bout of violence, and proposed rebuilding a concrete wall in front of the Interior Ministry to prevent protesters from reaching the building, the state-run Al-Ahram newspaper reported. It said the committee also recommended asking parliament to authorize "shooting anyone who tries to encroach the wall." The proposal, which has not been approved yet, immediately sparked an outcry among demonstrators and activists. Rights groups and several newly elected members of parliament have called on the country's military leader, Field Marshal Hussein Tantawi, who served as President Hosni Mubarak's defense minister for 20 years and took power after Mubarak's ouster last February, to immediately transfer power to a civilian administration. Some protesters Saturday urged for an end to the violence and called on people to leave the Interior Ministry area. "If you love Egypt, return to the (Tahrir) square," chanted protesters along the side streets of the ministry on Saturday. Police then cordoned off several streets with lines of riot police and barbed wire, pushing protesters further back from the building's headquarters. In the port city of Suez, protesters set up cordons outside the police headquarters to ban people from protesting around it and keep the calm after three days of violence there. On Friday, security forces in Suez opened fire on a crowd of several thousand outside the police headquarters. A total of seven people were killed, a police official said Saturday. The Health Ministry said Saturday that 2,500 people have been injured since the violence began on Thursday. There have been accusations that plainclothes officers took part in the soccer riot, and some have alleged that riot police intentionally allowed the melee in Port Said to happen to retaliate against die-hard soccer fans of the visiting team Al-Ahly, known as Ultras, who played a key role in clashes with security forces during the uprising that toppled Mubarak. Survivors have said police stood by doing nothing as Al-Masry fans attacked Al-Ahly supporters, stabbing them, undressing them and throwing them off bleachers. Others died from the stampede down a narrow corridor after the stadium's gate, which was locked from the outside, was forced open by the crowd. Prime Minister Kamal el-Ganzouri said he sacked the Egyptian Soccer Federation's board on Thursday and referred its members for questioning by prosecutors about the violence. To keep in line with international soccer federation guidelines, which do not give el-Ganzouri the right to dissolve the board, its eight members formally submitted their resignations on Saturday. The country's leading religious figure, Sheik Ahmed el-Tayeb of Al-Azhar mosque canceled Saturday's celebrations marking the birth of the Prophet Muhammad in light of the violence.
