The death toll from a collapsed mine waste reservoir in Xiangfen county, Shanxi province rose to 128 on Wednesday as angry residents suggested that it was a man-made rather than a natural disaster, Reuters reported. Rescuers continued their search for the dozens of victims still missing after a deluge of sludge from the waste reservoir swept through a market and submerged buildings. Excavators were used to dig through the mud blanketing fields and houses for several kilometers below the Tashan mine. Police kept friends and relatives looking for news of their loved ones away from the search site as tensions rose, with people accusing the mine operators of negligence and local officials of cold-hearted incompetence. Earlier state media reports suggested the reservoir may have been filled beyond capacity. The mine owner is said to have been arrested and several government officials sacked over the disaster.
