Inside a concrete room to my left, I could see more than 50 others being made to stand in uncomfortable positions  on their toes with their hands pressed behind their heads. Some were covered in blood, and police with batons patrolled the rows, tapping some detainees on the shoulders with their sticks. There was no screaming, just the sound of boots pacing on the concrete floor.
