SALE, Morocco - Moroccan authorities used tear gas and truncheons on Monday to put down a prison protest by accused Islamists who climbed on a roof demanding pardon or review of their cases, human rights activists said. Around 150 people took part in the protest at Zaki prison in Sale, northeast of the capital Rabat. At least 30 were injured including one who fell from the roof, said Binothmane Reda, a member of a coordination committee for ex-Islamist detainees. The prisoners' grievances include detailed allegations of torture and arbitrary treatment. The government says it treats detainees in strict accordance with the law.
