The Egyptian authorities say at least 73 people have died and more than 1,000 injured in northeast Egypt in clashes between rival football fans. The violence in the city of Port Said began when fans invaded the pitch after the home team al-Masry won a rare 3-1 victory against the visiting Cairo-based team al-Ahly. The deputy health minister described it as the biggest disaster in Egypt's football history. Jon Leyne, who's in Cairo, watched live coverage of the clashes.
