Chinese authorities are working quickly to reach survivors still trapped under a passenger ship that capsized -- or turned over -- in the Yangtze River late Monday. More than 450 passengers and crew were on board the ship when it went down. Most of the passengers were elderly Chinese tourists.

Only 15 people are known to have gotten out alive. More than 400 passengers are still missing. The People’s Daily website reported late Tuesday three bodies were found 50 kilometers from the wreckage site.
