Rescue workers in Chile have suspended their attempt to reach 34 miners trapped underground after a cave-in blocked search crews.
No contact has been made with the miners since a tunnel collapsed on Thursday at the San Esteban mine, near the city of Copiapo in northern Chile.
The miners were working at a depth of around 450m (1,475ft) and officials hope they took refuge in a shelter.
Major mining accidents are uncommon in Chile, the world’s top copper producer.
Three teams were attempting to reach the trapped miners using a ventilation shaft.
