At least one person has been killed as fans of rival football teams take to the streets in Egypt, angered by verdicts over last year's deadly stadium riots in Port Said. Fans of the Cairo club Al-Ahly, angered by the acquittal of seven police officers, set fire to a police officers' club and the football federation's headquarters in the capital. Hundreds of people also took to the streets in Port Said to protest against a Cairo court's upholding of the death sentences of 21 fans accused of sparking the riots that left 74 people - most of them Al-Ahly supporters - dead. Al Jazeera's Sherine Tadros reports from Cairo.
