Violence between fans of Port Said home team Al-Masry and Cairo's Al-Ahly broke out on Wednesday, marking one of the deadliest incidents in football history and erupting at the end of a match that saw Al-Masry win 3-1.
Witnesses said Al-Masry fans invaded the pitch, throwing rocks, bottles and fireworks at away supporters, causing chaos and panic as players and fans fled.
