Dozens of Zamalek's ultras fans chant against the interior ministry and former interior minister Habib el Adly during a peaceful march from the Cairo district of Shobra to Tahrir Square on September 9th.
Hundreds of ultras from Egypt's top two football clubs - Ahly and Zamalek - took part in Friday's protest. This followed clashes days earlier between Ahly fans and police after a cup match in which supporters say they were attacked by police after chanting against the interior ministry and deposed president Hosni Mubarak.
