Yet another deadly prison riot is reported from Brazil. This time, rival gangs clashed for control of a pavilion at Alcaçuz State Penitentiary, in the northeastern state of Rio Grande do Norte. The riot began early Jan. 14; police surrounded the prison that night, but waited until noon the next day to enter due to reports that rebel inmates had armed themselves. At press time, the state’s military police and elite Special Operations Batallion are trying to negotiate the surrender of the inmates, according to Brazilian news blog Plus55. The state government has confirmed at least 10 deaths, but the number is expected to rise—Reuters already puts it as high as 30. Some of the victims are said to have been decapitated.
