More than a dozen people were killed in a gunfight between armed civilians and the Mexican security sources near the U.S. border in northern Mexico, according to local media on Sunday.  

An hour-long gun battle took place in Villa Union, a town in Coahuila state, Miguel Angel Riquelme, the state governor told local media.

The mayor said 14 people were killed, including four police officers in the initial confrontation, and several municipal workers were missing.

The armed assailants are thought to be alleged members of the Cartel of the Northeast, a gang involved in drug trafficking.
