A giant sinkhole opened up and swallowed the front half of a public bus yesterday in China's Qinghai province. According to Vice News, six people were killed and at least sixteen were injured.
The bus was making a stop when the sinkhole opened up. Pedestrians worked to help get people out of the bus and some of them, including one retired police officer, were sucked into the massive sinkhole. Damage to utilities led to an explosion, with a fireball visible in the video below.
The cause of the sinkhole is not yet known.
