A heavily armed group of gunmen brutally massacred 10 people in a pool hall in an industrial region of central Mexico recently plagued by drug cartel violence.
According to the regional prosecutor's office, the massacre occurred in the municipality of Tarimoro in Guanajuato state late on Wednesday night.
Nine men were found dead at the scene and another was rushed to hospital where he later died of his injuries.
Diego Sinhue Rodriquez, the governor of Guanajuato, vowed to restore order in the area and condemned what he described as a "cowardly attack".
Guanajuato has seen a heavy spike in gang-related violence recently as a bloody dispute erupted between the Jalisco New Generation cartel and the Santa Rosa de Lima cartel, who fight for control of the lucrative drug trafficking markets in the region.
The Jalisco cartel is said to be "one of the five most dangerous transnational criminal organizations in the world," according to the Department of Justice. Nemesio Oseguera Cervantes "El Mencho", the leader of the Jalisco cartel is believed to be one of the most powerful drug lords in Mexico, and one of the most wanted men in the world.
Since December 2006, Mexico has recorded over 340,000 murders related to drug cartel violence. Many murders in Mexico go unreported, meaning the real figure is likely much higher.
