A day after 83 workers were buried following a massive landslide in a gold mining area in Tibet's regional capital Lhasa, over 1,000 rescue workers are braving difficult terrain to search for the survivors.

A State News agency reported that Police personnel, firefighters and medical staff are working together at the high-altitude site to carry out rescue operations. About 200 large vehicles and equipment, 15 sniffer dogs and 15 life-detector machines are being used in the rescue.

The victims were workers from Tibet Huatailong Mining Development Company Limited, a subsidiary of the China National Gold Group Corporation located about 68 km from provincial capital of Lhasa. An official from the regional fire department, said, the rescue will be difficult due to the size of the affected area.

Chinese President Xi Jinping and Premier Li Keqiang have ordered top efforts to rescue the buried workers.
