At least 13 inmates died in a prison riot in northern Mexico that authorities ended with lethal force, a state security official said late Tuesday.

Spokesman Aldo Fasci said the riot occurred at the state prison in Cadereyta and the death toll could climb because eight people were in critical condition.

Unrest at the prison in Cadereyta in northeastern Nuevo Leon state broke out in the morning and was put down. But it flared again later as inmates started fires that sent up huge columns of black smoke visible from far away.

One prisoner died in that fire. Prisoners then took three guards hostage, and when talks with them went nowhere, security forces were sent in, Fasci told reporters.

Police stormed the prison and inmates threw stones and struck them with iron bars, Fasci added.

Use of non-lethal force proved insufficient as some 250 inmates battled the security forces.

In the evening, "lethal force was used to prevent the killing of the three guards and so far the toll is 13 dead," said Fasci. Another 26 people were injured.

Cadereyta is on the outskirts of Monterrey, the third largest city in Mexico.

Rival gangs that are involved in drug trafficking, human smuggling, fuel theft, kidnapping and extortion have fueled bloody battles in Mexico's overcrowded prisons.

At least nine were killed in a prison fight in the state of Tamaulipas on the U.S. border with Texas and at least 28 inmates were killed in July in a battle in a prison in the Pacific resort of Acapulco.

In 2016, a vicious fight between rival gangs left 49 dead in the Topo Chico jail, also in Nuevo Leon.
