Gunmen have shot dead 13 people at a bar in the city of Minatitlan in the Mexican Gulf coast state of Veracruz, authorities say, in one of the worst slayings to hit Mexico since President Andres Manuel Lopez Obrador took office.
The unidentified assailants opened fire on Friday night local time after coming to look for a man at a bar in the southeast of Minatitlan, a spokesman for the government of Veracruz said.
Seven men, five women and a child died in the shooting, which occurred close to Minatitlan's oil refinery, one of six run by state oil firm Petroleos Mexicanos (Pemex). Some media is reporting the child was a one-year-old baby.
Four other people were injured, the state government said in a statement.
The motive for the killings was unclear, the spokesman said.
The man the gunmen were seeking was identified as the owner of a bar in the city, the state government said. The attack took place during a family celebration.
It was not immediately clear if the man owned the bar where the attack occurred, nor whether he was present at the time.
