At least six people have died and dozens more are missing after an open-pit coalmine collapsed in Inner Mongolia, an autonomous region in north China.
One of the walls of the mine caved in at about 1pm local time on Wednesday, burying workers in tonnes of rocks and sand. Another collapse occurred five hours later, forcing the rescue operation to halt. The search resumed on Thursday morning, with fireengines, SUVs, bulldozers and rescue dogs being mobilised from across the province.
