HONG KONG — At least six people have been killed and more are missing after a bus plunged into a sinkhole in the city of Xining, in northwestern China.
Video footage circulating on Chinese social media on Monday shows several people waiting to board the bus in Xining, the capital of Qinghai Province, when a traffic sign wobbles and the vehicle begins to sink into the road.
Bystanders rushed to help passengers escape from the sinkhole, which was at least 32 feet in diameter, according to Chinese state media, but they backed away as the bus slipped further into the widening hole.
Rescue crews worked overnight to free trapped passengers. Local business owners said they tried to help by breaking the bus windows to reach passengers.
Officials in Xining said Tuesday morning that 10 people were missing and 15 more injured.
A sinkhole in the southeastern city of Xiamen in December swallowed subway trains. That same month, three people fell into a sinkhole near a subway line under construction in Guangzhou, in southern China.
In 2013, a sinkhole engulfed an entire building complex in Shenzhen, an industrial city on the border with Hong Kong.
