Chongqing Tunnel Massacre
This tragedy occurred on June 5, 1941, when people were escaping from the Japanese Bombing of Chongqing in the Second Sino-Japanese War. A crowd of people were trying to make their way to the air raid shelters built by the Chinese government. Tens of thousands of people entered to the Shiba Ti Tunnel bomb shelter and they were locked from the outside to avoid being hit by bombs. The tunnel was designed to only hold 4,000 people, so it was way overcrowded.
There was very poor circulation in the tunnel, and toxic gas and carbon dioxide was filling up the already crowded space. Many people were beginning to suffocate. Crowding and lack of oxygen caused a stampede to get out of the tunnel, crushing the people who were in the only way out. It took 5 days to remove the 992 dead and 4,000 injured.
