Mexican drug cartel attack death toll rises to 21

Mexican officials say security forces have killed seven more members of the gang that attacked a town near the US border, taking the death toll to at least 21.

The Coahuila state government says police are still chasing remnants of the presumed drug cartel force that attacked the town of Villa Union on Saturday.

The governor reported at least 14 people had died by that afternoon, four of them police.

He also said then that several municipal workers were missing. It’s not known if they have yet been found.

The government said the gang fought an hour-long battle with security forces before fleeing along paths into rugged terrain.

The town is about 12 miles from the site of a 2011 cartel massacre in which officials said 70 died.
