A task force has been sent to “control the disturbances,” officials said.
Several other inmates were injured in Monday’s incidents, according to Brazil’s Globo news website (in Portuguese).
The majority of the victims were discovered at the Antônio Trindade institute near Manaus, while deaths were also reported at the Puraquequara and Provisional Detention Centre facilities in Amazonas state.
