PIEDRAS NEGRAS, Mexico (AP) — Mexican authorities say gunmen rampaged through a town in the northern border state of Chihuahua, killing at least six people, including a child.

State prosecutors say the attack happened late Friday in the town of Guadalupe y Calvo. They say six bodies were found in three different neighborhoods. A house also was burned.

In the Mexican border state of Coahuila, officials say seven suspected organized crime members died during two clashes with the military early Saturday.

Four were killed when marines fought with an armed group before dawn in the town of Morelos. Three others died minutes later in a battle between army special forces soldiers and gunmen 37 miles to the north (60 kilometers) in the border town of Piedras Negras, which is next to Eagle Pass, Texas.
