Violence erupted on Thursday morning at the El Castillo Penitentiary in the port city of Mazatlan. According to local media, firearms were involved and the sound of gunshots inside the prison can be heard in footage recorded outside the jail's perimeter. Sinaloa's public security secretariat said nine prisoners were killed in the violence as well as one family member. A child was among the dead but it is not clear whether they were an inmate. Meanwhile 16 inmates were taken for medical treatment after being injured in the firefight.

The prison, which houses 1,800 inmates, is now 'under control' according to Mexico's federal security cabinet. Experts say overcrowding, driven in part by the use of pretrial detention – which keeps thousands of people behind bars without a sentence – combined with insufficient prison staff, has fueled corruption and violence inside Mexican jails. Last May, a riot broke out at a prison in Culiacan, the capital of Sinaloa, leaving seven prisoners dead and another injured. Mexico has 276 prisons, including 14 federal penitentiaries and 249 state prisons. The prison population reached 261,388 people as of February, according to official figures.Violence erupted in Sinaloa in September 2024 amid an internal power struggle between two factions of the Sinaloa Cartel, pitting the sons of convicted former drug lord Joaquín 'El Chapo' Guzmán, known as 'Los Chapitos', against followers of another detained former cartel leader, Ismael 'El Mayo' Zambada.The deadly riot on Thursday came as Donald Trump pressures the Mexican government to crack down on cartels.
