In a statement Saturday, the main opposition National Salvation Front said it holds Morsi responsible for "the excessive use of force by the security forces against protesters." They threatened to boycott upcoming parliamentary elections if Morsi does not meet their demands that include amending articles in the new constitution.
The Brotherhood said in its statement that "misleading" media outlets were to blame for "enflaming the people's hatred for the current regime and urging them to act violently."
Immediately after Saturday's verdict was read live on state TV, two policemen 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.
In other parts of the city, residents tried to storm the governor's office, police stations, the power station and the main court building. Residents occupied one police station in the east of Port Said.
The director of hospitals in Port Said, Dr. Abdel-Raham Farah, said two local soccer players were shot to death as they were apparently on their way to practice. He identified them as Mahmoud Abdel-Halim al-Dizawi, who played for the city's Al-Marikh club, and Tamer al-Fahla, who used to play for the city's main Al-Masry team. Al-Diwazi was shot three times, the doctor said.
The club they were training at is near the prison that residents tried to storm.
The military was deployed in Port Said to try to restore security, but assaults continued into the evening. The army was widely used to keep order by top generals who took over after Hosni Mubarak, but the military has kept a much lower profile since Morsi was elected.
