Hooded gunmen kill 13 in Mexico

Gunmen stormed a rural town in southern Mexico and killed 13 people in an attack that is believed to be drug-related.

Hooded assailants in several cars killed nine police officers at a checkpoint in San Vicente Camalote, a town in southern Oaxaca state, local officiall Netolin Chavez said.

The gunmen then burst into the ranch killing four, Mr Chavez said. He said investigators believe the Tuesday's attack was related to drugs, but he had no other details.

State police were sent to patrol the town.

Oaxaca, a Pacific coast state with ancient Zapotec ruins and pristine beaches, is considered a drug trafficking corridor, although violence has not risen to the levels plaguing Mexico's northern border region.
