A huge sink swallowed a bus and pedestrians in northwest China, causing an explosion, killing six people and leaving four others missing, state media said Tuesday.
The images showed people at a bus stop moving away from the collapse of the road when the vehicle, which stood out in the air, sank to the ground.
Several people disappeared into the sink as it spread, including what appeared to be a child. The incident also caused an explosion inside the hole, the video showed.
Sinks are not unknown in China, where they are often attributed to construction sites and the country’s rapid pace of development.
The incident occurred around 5.30 p.m. (local time) on Monday in Xining, the capital of Qinghai Province, state television channel CCTV said.
A search and rescue operation that involved more than 1000 people and 30 vehicles was underway, according to the official Xinhua news agency. An investigation into the cause has been opened.
The video images published by the state broadcaster CGTN showed a person who was rescued from the well by rescue workers.
The collapse left a hole of 80 square meters in the street in front of a hospital.
The 16 injured were taken to the hospital and are in stable condition, Xinhua added, citing a local emergency management official.
An earlier report indicated that 10 people were missing, but Xinhua said four were missing.
In 2016, at least three people fell into a large sink in the central province of Henan, which swallowed a section of the road and passersby.
An initial investigation showed that the collapse could have been caused by buried water pipes beneath the road that broke due to the rain.
In 2013, five people died when a 10-meter wide sump opened at the doors of an industrial estate in Shenzhen.
