CAIRO (AP) -- Egyptian security officials say a senior police officer and a policeman were shot dead in the Mediterranean city of Port Said after a judge sentenced 21 people to death in connection to one of the world's deadliest incidents of soccer violence.
Officials say that the police were killed when relatives tried to break into the Port Said prison to free the 73 defendants in the case held there.
At least 75 people were wounded in Saturday's violence outside the prison. Port Said residents also cut off the main road leading to the city.
Officials spoke anonymously in line with regulations.
The violence comes after a judge sentenced fans of Port Said's Al-Masry team to death for taking part in the Feb. 1, 2012, soccer violence, which killed 74 fans of Cairo's Al-Ahly club.
