Gunmen attacked a prison in the northern Mexican city of Ciudad Juarez on Sunday, leaving 14 people dead and allowing 24 inmates to escape, the Chihuahua state prosecutors’ office said.
An unknown number of gunmen aboard armored vehicles took part in the attack, and the dead included 10 prison guards and security agents, the office said in a statement.
Some five hours after the dawn incursion began, security forces managed to control the situation, which had also erupted into fighting between inmates within the sprawling state prison, near Mexico’s border with the United States.
Moments before the attack, armed men fired on municipal police along a nearby boulevard, setting off a car chase that ended with the seizure of a vehicle and four men, the statement added.
Later, assailants in a Hummer fired on another group of security agents outside the prison, it said.
Scenes of chaos ensued as relatives of some prisoners waited for New Year’s visits outside the compound.
Inside, some rioting inmates set fire to various objects and clashed with prison guards, local media reported.
Prosecutors said the outbreak at the prison, where inmates from differing criminal bands and drug cartels are housed in separate cellblocks, also left 13 people injured.
Four people were detained, prosecutors said, without specifying if they were inmates or armed assailants.
Details were not available about how the 24 escaped inmates were able to flee.
Prosecutors in the city, which sits across the border from El Paso, Texas, said they were investigating the motive of the attack.
Ciudad Juarez was the scene of years of violent clashes between security forces and the rival Sinaloa and Juarez drug cartels, which have left thousands dead over the past decade.
The prison itself has seen multiple breakouts of fighting and riots, including a bloody March 2009 episode that left 20 dead.
In August 2022, a clash between rival gangs left three prisoners dead.
According to a February 2022 report by the State Human Rights Commission, more than 3,700 people are detained in the prison, above its maximum capacity of 3,135.
Mexican detention centers, particularly those run by the state, suffer from chronic overcrowding and violence, which has worsened in recent years due to conflict between criminal groups.
