Twelve people were killed in a shooting at a bar in central Mexico on Saturday, local authorities said.
Police said Saturday's attack took place when an armed group entered the bar in the city of Irapuato in Guanajuato state at around 8 p.m. (0100 GMT) and opened fire on customers and staff.
At least six men and six women were killed, and three others were injured, the municipal government said in a statement, without specifying the attackers' identity or motives.
Security officials were trying to track down the assailants.
The attack is Guanajuato's second mass shooting in less than a month. Guanajuato, a major manufacturing hub and production site for many of the world's top carmakers, has been convulsed in recent years by brutal turf wars between rival drug gangs.
