Nations Cup to hold silence after Egypt deaths
Seventy four people died and at least 1,000 were injured when supporters invaded the pitch at a match in Port Said on Wednesday.
Most of the deaths were among people trampled in the crush of the panicking crowd while others fell or were thrown from terraces.
"African football is in a state of mourning," said Issa Hayatou, president of the Cairo-based Confederation of African Football (CAF) in a message of condolence to the Egyptian Football Association.
The quarter-finals of the Africa Cup of Nations are played in Equatorial Guinea and Gabon on Saturday and Sunday.
Egypt, who won the last three tournaments, failed to qualify for this year's edition.
