Heavy fighting broke out in northern Mexico after the security forces seized one of the sons of jailed drug kingpin Joaquín "El Chapo" Guzmán.

Fighting raged for several hours after Ovidio Guzmán López was found during a routine patrol in the city of Culiacán.

Footage showed heavily-armed men firing on police, with cars, bodies and burning barricades strewn in the road.

Police withdrew without Mr Guzmán in their custody to avoid further violence, officials said.
