At least 500 industrial workers were evacuated following an explosion in a gas pipeline in San Miguel Xoxtla, a town in the central Mexican state of Puebla, but no one was injured in the blast, emergency management officials said.
A pipeline belonging to state-owned oil giant Petroleos Mexicanos, or Pemex, exploded Saturday morning, Puebla state emergency management office director Jesus Morales said.
The pipeline runs along the side of a highway that connects the town to Mexico City, Morales said.
Army troops and police brought the fire under control and investigators are trying to determine what caused the explosion . . .
