Survivor 'could hear people screaming for help'

After 10 hours of floating in a life jacket down the Yangtze River, Zhang Hui was finally rescued.

But many others who were on board the cruise ship Eastern Star had no chance to put on life jackets because the ship capsized so quickly, Zhang said.

The ship, heading from Nanjing to Chongqing with456people on board - including five tour agency staff members and a crew of 46 - cap-sized at 9:28 pm on Monday when it reportedly encountered a tornado in central China's Hubei province.
