Al-Ahly Ultras in particular have been at the forefront of protests. But anger also is boiling in Port Said, where residents say they have been unfairly scapegoated.
Immediately after the verdict, two police were shot dead outside Port Said's main prison when angry relatives tried to storm the facility to free the defendants. Police fired tear gas and rubber bullets, as well as live rounds, at the crowd outside the prison, killing 14, security officials said. Hundreds were wounded. They spoke on condition of anonymity in line with regulations.
Security officials said the military is being deployed to Port Said — the second such deployment in less than 24 hours. The army was widely used to keep order by top generals who took over after Mubarak, but the military has kept a much lower profile since Morsi was elected as president in June.
Morsi cancelled a scheduled trip to Ethiopia Saturday and instead met for the first time with top generals as part of the newly-formed National Defense Council.
The military was also deployed overnight in the city of Suez after eight people died in clashes between security forces and protesters opposed to Morsi. Another protester was killed in Ismailiya, and security officials told the state news agency MENA that two policemen were killed in Friday's protests, bringing the death toll on the second anniversary of Egypt's uprising to 11.
