Two football players are among 27 people killed in riots in the Egyptian city of Port Said, the area's director of hospitals said.
Violence erupted in Port Said after a judge sentenced 21 people to death in connection with soccer violence that left 74 fans of the Cairo-based Al-Ahly team dead.
Dr Abdel-Raham Farah said Mahmoud Abdel-Halim al-Dizawi, a football player in Port Said's Al-Marikh club, was shot three times and died. He said Tamer al-Fahla, a footballer who used to play for the city's main Al-Masry team, was also shot dead on his way to the Al-Marikh club.
The club is near a prison residents tried to storm on Saturday to free defendants in the football trial. The military has been deployed to try and restore security.
The verdicts follow deadly clashes between police and demonstrators on Friday, the second anniversary of the uprising that overthrew long-time leader Hosni Mubarak. Such cycles of violence, often lasting for weeks and costing dozens of lives, have occurred regularly over the past two years.
Die-hard soccer fans from both teams, known as Ultras, hold the police at least partially responsible for the Port Said deaths and criticise Egypt's president Mohammed Morsi for doing little to reform the force. Al-Ahly Ultras has been at the forefront of protests but anger is also boiling in Port Said, where residents say they have been scapegoated.
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 new agency Mena that two policemen were killed in Friday's protests, bring the death toll on the second anniversary of Egypt's uprising to 11.
Judge Sobhi Abdel-Maguid read out the death sentences. Defendants' lawyers said all those sentenced were fans of the Port Said team, Al-Masry. Executions in Egypt are usually carried out by hanging.
The judge said in his statement, read live on state TV, that he would announce the verdict for the remaining 52 defendants on March 9. Among those on trial are nine security officials, but none have yet been handed sentences, lawyers and security officials say.
Fans of al-Ahly, whose stands were attacked by rival club Al-Masry, had promised more violence if the accused did not receive death sentences. In the days leading up to the verdict, Al-Ahly fans warned of bloodshed and "retribution".
