TUNIS: Police and fans were injured in clashes during the Tunis derby between arch-rivals Club Africain and Esperance Sportive de Tunis on Sunday, the interior ministry said Monday. Police used tear gas following confrontations with Club Africain supporters at the Rades Olympic stadium, in the suburbs of Tunis. “More than 10 police and security agents were injured,” the interior ministry said. “A group of people involved in the violence have been arrested.” CA president Slim Riahi blamed ‘provocation’ by security staff towards supporters. Interior Ministry spokesman Yasser Mesbah insisted security officials ‘had been targeted’ by violent fans, with his office publishing photos of ripped up seats and bottles strewn across the pitch. “We have a problem of morals and mentality,” said Sports Minister Majdouline Cherni.
