An hour-long cartel versus cops gun battle left 14 dead and a Mexican town looking like a bullet-pocked war zone on Sunday.

Four of those who died were cops after a truck convoy carrying suspected cartel members rolled into a town in Coahuila state, officials said.

Photos from Villa Union, a town of 3,000 residents about an hour drive southwest of Eagle Pass, Texas, show the front, side, and back of the town’s municipal building strafed by gunfire.

Another photo shows a bullet-damaged, partially-wrecked pickup truck with Texas plates. On the truck’s driver’s side door can be seen the letters C. D. N. — which stands in Spanish for Cartel of the Northeast.

It was unclear what may have prompted the armed group to storm the town.

Security forces will remain in the town for several days to restore a sense of calm, the governor said.

“These groups won’t be allowed to enter state territory,” the government of Coahuila said in a statement.
