In a revolt in a Brazilian prison, two prisoners have been beheaded and another killed by being thrown off a roof. The revolt started over the conditions of life in the jails, as prisoners were demanding better food and medical care in the prison, according to Jairo Ferreira, lawyer for the prison guards' union. The conviction of two inmates would be also linked to the riots. Many rioters raised banners emblazoned with the initials PCC, for a criminal prison gang formed in the 1990s. 80% of the prison would be currently under control of the rioters. Negotiations for better conditions of life are actually under way, 12 hours later.
