At least 17 workers have been buried by a rockfall while working to repair a railway line in southwest China.
Rescue teams have so far recovered the bodies of four workers who died in Ganluo County, Sichuan Province, the official Xinhua news agency reported.
Hundreds of rescuers are searching for the remaining missing workers with the help of drones and other equipment.
The cause of the landslide is unknown, and the workers were repairing the railway damaged in the previous landslide on that section.
