CAIRO - Rock-throwing protesters fought riot police through clouds of teargas to within meters of Egypt's Interior Ministry on a second day of clashes triggered by the deaths of 74 people in the country's worst soccer disaster.A demonstrator and an army officer were reported dead in Cairo and in the city of Suez two people were killed as police used live rounds to hold back crowds trying to break into a police station and fought in front of the state security headquarters, witnesses and the ambulance authority said.Most of those killed in the Port Said football stadium on Wednesday night were crushed in a stampede and the government declared three days of mourning, but protesters hold the military-led authorities responsible.It was country's deadliest incident since an uprising ousted Hosni Mubarak almost a year ago and it gave fresh impetus to regular street protests against Egypt's ruling generals."We will stay until we get our rights. Did you see what happened in Port Said?" said 22-year-old Abu Hanafy, who arrived from work on Thursday evening and decided to join the protest.The ministry in Cairo, an object of hatred for football fans who say lax policing was to blame for the stadium disaster, has been hemmed in by the street battles since Thursday.Thousands were still battling riot police there and more protesters were expected to gather in the center of the capital for a "Friday of Anger" declared by 28 youth activist groups and political parties.A Reuters witness heard firing and found gun pellets on the ground. A core of demonstrators had heaved aside a concrete barrier blocking a main road near the ministry overnight to get closer to the building."We pulled it down with our bare hands," said Abdul-Ghani Mohamed, a 32-year-old construction worker. "We are the sons of the pharaohs."Ambulances had to intervene overnight to extract riot police whose truck took a wrong turn into a street full of protesters.Police fired round after round of teargas but the wind picked up on Friday afternoon to waft the fumes back to the police lines, leading the rioting protesters, some of whom waved soccer team flags, to cry "God is Greatest."Some of the demonstrators, mostly men in their late teens and 20s, goaded the security forces defending the neat five-story ministry building, shouting "The army, the police - one filthy hand."Close to 400 people have been hurt in the confrontations since Thursday, the Health Ministry said, many of them by inhaling teargas.An army lieutenant was killed by a security vehicle that ran over him by mistake, Health Ministry officials said.Rocks thrown by protesters were strewn across streets that two months ago witnessed violent clashes between police and activists who see the Interior Ministry as an unreformed vestige of Mubarak's rule.Hardcore football fans known as "ultras," who often clash with the police and were at the forefront of the uprising against Mubarak, vowed to continue their protests."The crimes committed against the revolutionary forces will not stop the revolution or scare the revolutionaries," said a pamphlet printed in the name of the ultras.In Suez, witnesses said fighting broke out at a local police station in the early hours of Friday. "We received two corpses of protesters shot dead by live ammunition," said a doctor at a morgue.Many shops in Suez were wrecked and the facade of the Suez Canal Bank was destroyed.Police cordoned off the Suez state security headquarters and a Justice Ministry compound with razor wire and seven burned-out vehicles lay nearby. Roads were strewn with glass.The soccer stadium deaths have heaped new criticism on the military council that has governed Egypt since Mubarak stepped down. Critics regard the generals as part of his administration and an obstacle to change.The army leadership, in turn, has presented itself as the guardian of the "Jan. 25 revolution" and promised to hand power to an elected president by the end of June.
