At least 26 people have been killed in a clash of armed groups in northern Mexico, authorities said.
Chihuahua state prosecutors' spokesman Felix Gonzalez says members the La Linea gang and a faction of the Sinaloa cartel were involved in the incident.
Mr Gonzalez told Milenio television that the gunfight occurred early on Wednesday morning in the town of Las Varas, about 185 miles north-west of the state capital.
He said investigators were still at the remote scene.
Mexico is experiencing its highest murder total in at least 20 years as splintered drug cartels battle for territory.
