Eleven were migrant workers who were killed when a landslide buried the tent they were sleeping in at an iron mine in northern Shanxi province, Xinhua reported. Only one person survived.

All the victims were men aged from 25 to 45.

Seven workers at an oilfield in northwest Gansu province were also killed Thursday by a mudslide caused by heavy rain, the Lanzhou Morning Post said.

Fifteen other workers were injured and two were missing.

Rescuers in central China's Hunan province meanwhile found the remains of 25 farmers killed in a flash flood on June 25, Xinhua said. Two others remained missing.
