„This is the biggest prison massacre in our state’s history“

(RIO DE JANEIRO) — At least 60 inmates died during a prison riot in the northern state of Amazonas, including several who were beheaded or dismembered, Brazilian state authorities said Monday.

State public security secretary Sergio Fontes said that in addition to the deaths, some inmates escaped, but he did not say how many. Several prison guards were held hostage.

“This is the biggest prison massacre in our state’s history,” Fontes said during a press conference. The riot began Sunday afternoon and lasted until Monday morning.

Two of the biggest crime gangs of Brazil began fighting last year over control of several prisons and authorities in Amazonas believe that’s the reason behind the first riot of 2017.
