Egypt has declared three days of mourning for the more than 70 people who died at a football stadium amid violent clashes between rival supporters in the northern city of Port Said.

Angry members of parliament denounced the lack of security at the match and gathered for an emergency session on Thursday, a day after violence erupted following an upset victory by home team al-Masry over Cairo's top club, al-Ahly.
