A landslide triggered by local residents digging for rumored deposits of gold in an abandoned mine killed at least 21 people and injured another 26 Saturday in southern Colombia, authorities said. Seven of those injured were in serious condition, Cauca provincial Gov. Juan Jose Chaux said in a statement. Chaux said the search for survivors at the mine, located near the town of Suarez, 220 miles (354 kilometers) southwest of Bogota, was suspended Saturday evening because of darkness and bad weather, which made the open pit mine unsafe. It was unclear how many people were missing, but earlier, police Officer Jose Delgado had told The Associated Press that about 50 people may have been in the mine at the time of the landslide. But he added there was no registry or official count of how many people entered the mine.
