AlQa'dah 29, 1436, Sep 13, 2015, SPA -- A disturbance at an Oklahoma prison left three inmates dead and five injured, months after several prisoners were hurt during a large brawl at the facility. The disturbance Saturday lasted about 40 minutes and was contained to one housing pod at the Cimarron Correctional Facility in Cushing, said Steve Owen, a spokesman for Corrections Corporation of America, the Tennessee-based company that owns and operates the prison. No staff members were injured in the incident, which he said staff quelled around 4:40 p.m. The inmates who were hurt were taken to hospitals. It's not clear what caused their injuries, AP reported.
