The Egyptian police say 11 officers were hurt when angry Tunisian football fans ripped out stadium seats, threw them about and hurled fireworks into the pitch during a tense weekend match between Al-Ahly and visiting Esperance of Tunisia.
A police report released on Monday says the disturbance took place during the first leg of an African Champions League semifinal played Sunday evening in Cairo. The host Al-Ahly won 2-1.
The police say dozens of Tunisians were arrested after policemen rushed into the stands to stop the fans from rioting.
Egyptian TV carried live footage of half-naked Tunisian fans beating up and kicking the policemen.
Egypt and north African countries have a history of football matches soured by fan violence.
