The Mexican police have launched a search for the gunmen responsible for Saturday’s gunfight in the town of Villa Unión.
According to police reports, dozens of gunmen drove into the town in the northern Mexican state of Coahuila at about midday local time (18:00 GMT) and started firing at the town hall, where the headquarters of Villa Unión’s police force sits.
About 500 shots were fired in the gunfight between the police and the gunmen believed to be members of a local drug cartel popularly known as Cártel del Noreste (Northeast Cartel).
Twenty-one people, including four police officers and ten gunmen, were killed in the gunfight.
Coahuila Governor Miguel Ángel Riquelme said the gunmen took several locals hostage while retreating from the town.
The police are still pursuing the gunmen who escaped on a dirt road.
