Judge Sobhi Abdel-Maguid read out the death sentences related to the Feb. 1 riot in Port Said that killed 74 fans of the Cairo-based Al-Ahly team. 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 Saturday 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 were handed sentences Saturday, lawyers and security officials say.
Fans of al-Ahly, whose stands were attacked by rival club Al-Masry in the Feb. 1 incident in Port Said, 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". Hundreds of Al-Ahly fans gathered outside the Cairo sports club in anticipation of the verdict, chanting against the police and the government.
Before the judge could read out the names of the 21, families erupted in screams of "Allahu Akbar!" Arabic for God is great, with their hands in the air and waving pictures of the deceased. One man fainted while others hugged one another. The judge smacked the bench several times to try and contain reaction in the courtroom.
"This was necessary," said Nour al-Sabah, whose 17 year-old son Ahmed Zakaria died in the melee. "Now I want to see the guys when they are executed with my own eyes, just as they saw the murder of my son."
The verdict is not expected to calm tensions between the two rival teams. The judge is expected to make public his reasons for the death sentences March 9, when the remaining 52 defendants receive their sentences.
