Prison riot in Mexico's Sinaloa state leaves 10 dead

A prison riot in Mexico's violence-ridden state of Sinaloa on Thursday resulted in the deaths of nine inmates and one visitor, with 16 other inmates injured, the state's security office said.

Prosecutors will investigate what caused the incident, and the prison is now under control, the office said in a statement.

In a separate incident on August 3, 2025, a prison riot at the Tuxpan Social Reintegration Center in Veracruz state left seven inmates dead and eleven injured. That unrest reportedly began after inmates asked authorities for protection against threats from inmates associated with the criminal group Grupo Sombra. Conflicts between cartels and organized crime groups are often replicated in Mexico's overcrowded prisons.
