Summary

A violent incident at El Castillo Penitentiary in Mazatlán, Sinaloa, Mexico, on October 8, 2026, resulted in 10 deaths—nine inmates and one visiting minor—and 16 injured inmates. The incident occurred during family visiting hours. Gunshots were heard inside the prison in footage recorded outside the facility's perimeter, and an armoured vehicle and ambulances were witnessed arriving at the scene by an AFP reporter. Multiple reports indicate inmates used firearms during the violence, though authorities have not provided details on what triggered the incident or how weapons entered the facility. The cause remains under investigation. Security forces, including military personnel, National Guard troops, naval forces, and state security officers, were deployed and restored control of the facility. Prison visits were subsequently suspended as a precaution. The prison, which houses 1,800 inmates, is now under control.
