A tunnel collapsed in a gold mine in southern Ecuador on Friday, trapping four miners 490 feet (150 meters) underground. Authorities said rescue efforts were under way.
A miner who survived the cave-in told authorities that four of his colleagues remain trapped in the mine, located near the city of Portovelo, about 250 miles (400 kilometers) southwest of the capital, Quito. The mine is operated by the Ecuadorean company Minesadco.
The collapse happened at 3:30 in the morning and blocked a tunnel, trapping the workers at the fifth level of the mine, Deputy Mining Minister Jorge Espinosa said. The condition of the men was unknown.
