BEIJING (AP) -- Chinese state media say a large landslide has trapped 83 workers in a gold mining area in Tibet.
China Central Television cited a local official as saying the landslide on Friday covered around 4 square kilometers (1.5 square miles) in the Maizhokunggar county of Lhasa, the regional capital.
The official Xinhua News Agency says the workers were from a subsidiary of the China National Gold Group Corp.
The reports said the landslide was caused by a "natural disaster" but did not provide specifics.
They said rescue efforts were under way Friday night.
County officials reached by phone confirmed the landslide but had no further details. Calls to the company's general phone line rang unanswered.
