Brazilian authorities said that the inmates responsible for the killings of 60 rivals at two prisons in the Amazon region will be transferred to high-security federal institutions in addition to being prosecuted. Many of those slain were beheaded or dismembered in the worst bloodshed at a prison of the South American country since 1992.

Amazonas state public security secretary Sergio Fontes said the transfers will begin as soon as investigations into the incidents are finished. He said there was a link between the killing of 56 inmates in a penitentiary in Manaus, the state capital, and four deaths in a smaller prison.
