The attack took place in El Mirador, a mountain community in central Puebla state, a region that has been relatively spared from the drug violence plaguing other parts of Mexico.
"We can confirm 11 deaths: five women, four men and two girls. Two other minors were badly wounded and taken to the hospital," said Vicente Lopez de la Vega, the mayor of the town of Coxcatlan, which oversees El Mirador.
A Puebla state government official, who spoke on condition of anonymity because they were not autorized to speak publicly, confirmed the massacre.
While drug violence is uncommon in Puebla, it has seen a spate of mob lynchings of crime suspects.
