A massacre in a bar left 11 people dead on Sunday, authorities in Mexico have said.
The bodies of scene men and four women were found in the bar in the early hours of Sunday morning in the city of Jaral de Progreso, the attorney general's office of the state of Guanajuato said.
Another woman was also found with gunshot injuries.
It comes as the country grapples with a record homicide rate despite the government's pledge to stop gang violence.
Guanajuato, a major car-making hub, has become a recurring scene of criminal violence in Mexico.
It has been ravaged by a turf war between the local Santa Rosa de Lima gang and the powerful Jalisco New Generation Cartel.
In July, gunmen killed 24 people at a drug rehabilitation center in Guanajuato.
It marked one of the worst mass slayings since President Andres Manuel Lopez Obrador took office pledging to reduce record levels of violence.
