3 children among 6 killed in latest "massacre" of family wiped out by hitmen in Mexico

A family of six, including three children, were killed Friday by gunmen in the southern Mexico border state of Chiapas in a town marred by cartel-backed militia violence.

Julio Pérez, the mayor of the Chiapas town of Pantelho, said the killings happened there Friday, and called it "a massacre." Two warring militia groups suspected of being backed by drug cartels have been battling for control of the town.

In a brief statement, the state prosecutor's office said three suspects were arrested but neither the victims nor the detainees have been identified.
