22 die as fans' death sentences spark Egypt unrest
At least 22 people have died in the Egyptian city of Port Said, in clashes sparked by the sentencing to death of 21 local people over football riots.
Supporters of the defendants tried to storm the prison holding them and attacked police stations.
The 21 were sentenced over riots which killed 74 people after a football game at Port Said stadium last February.
Saturday's violence follows a day of unrest on the second anniversary of the uprising that ousted Hosni Mubarak.
Thousands of people took to the streets on Friday to voice their opposition to Islamist President Mohammed Morsy, accusing him of betraying the revolution.
At least seven people were killed and more than 450 wounded in unrest across Egypt.
All 21 defendants sentenced to death on Saturday were fans of Port Said club al-Masry. When the verdicts were announced by a judge in the Cairo court, relatives of victims cheered.
However, the ruling caused supporters of the defendants to go on a rampage in Port Said, Two police officers were shot dead outside the city's prison.
At least another 20 people were killed and about 200 were wounded in further clashes, officials said. Army units were deployed on the city's streets.
Last year's football riots led to the suspension of the league.
They began minutes after the game, when al-Masry fans invaded the pitch, hurling stones and fireworks at visiting supporters from Cairo club al-Ahly.
A section of al-Ahly supporters, known as the "ultras", played a prominent role in the protests against ex-President Mubarak.
Some accused supporters of the toppled leader of instigating the Port Said violence. They also accused police of doing little to prevent the violence.
Seventy-three people, including nine policemen, were tried over the stadium clashes. None are al-Ahly fans.
The judge said he would announce verdicts for the remaining defendants on March 9.
