GUIYANG, China – At least 21 people were confirmed dead and several others injured when the bus they boarded plunged into a river Saturday night in Guizhou Province, southwest China, authorities confirmed on Sunday.

Initial investigation showed that the bus suddenly swerved off a mountain road and plunged directly onto a dry riverbed in Nayong County, Bijie City, according to rescuers who responded at the site.
