Bahrain prison riot

"The guards tended to be from Jordan, Pakistan or Yemen and were exclusively Sunni Muslims who would insult the mostly-Shia inmates and their religion, he said. "They treated us like animals and they would [use] sectarian terms when they called to us," he said. Once the riot was quelled, the prisoners were put in a circle and forced to sing songs praising Bahrain's King Hamad bin Isa Al Khalifa and disparaging their own protest movement leaders. They were regularly beaten by the guards, Johar said, forced to sleep outside and deprived of food and toilet facilities for two days." (thanks Amir)
