In Columbia, at least four people have died and 18 are missing after a mudslide swept through the town of Corinto in Colombia's south-west Cauca province. Emergency workers said the La Paila river burst its banks and swept mud, boulders and branches through the town's centre. <br/><br/>Residents have been evacuated as the risk of further mudslides remains high because the river bed is blocked by debris. President Juan Manuel Santos said firefighters had been deployed to help residents of the affected area.
