At least 91 people remained missing Monday after red mud buried 33 buildings in China, NBC News reported.
Heavy rain in the region had saturated the soil, making a large pile of construction waste and mud increasingly unstable. The force ultimately caused it to collapse, NBC News said.
The landslide swamped 450,000 square yards of three industrial parks in the southern city of Shenzhen on Sunday, according to Chinese state media. Low-rise buildings, factories and homes were covered, while gas pipeline exploded.
China’s Xinhua media agency reported that 14 people had been rescued and that 900 others were evacuated Sunday. The mud was believed to be as high as 20 feet in some areas.
