At least 30 Egyptians died on Sunday after police attacked Zamalek football fans at the Air Force stadium in New Cairo.
Fans said they were waiting to go in through a tiny gate when they were teargassed. This led to a stampede, followed by security forces repeatedly attacking people.
Many of the victims were teenagers.
Football fans played a role in the Egyptian revolution and are hated by the authorities.
Incredibly the game went ahead regardless and only one player refused to appear.
