Gunmen who have not been identified yet opened fire at a bar in Mexico on Saturday evening. 

12 were killed in the violence in Irapuato, Mexico, according to Reuters, including six women and six men. In addition, three people were also injured. 

The authorities, in a statement, said that security officials were working to track down and identify the gunmen. Given that the victims were customers, the motive behind the shooting is still unknown. 

This would mark the second mass shooting in Guanajuato state in less than a month.
