Dozens of people broke through a police cordon on Wednesday as they marched toward the site of a sunken cruise ship in the Yangtze River to demand news of missing relatives.

Rescuers searched for more than 400 missing people, many of them elderly, but hopes were fading of finding more survivors from the worst shipping disaster in modern Chinese history.

Only 14 people, including the ship's captain, have been found alive since the ship capsized in a tornado on Monday night with 456 people on board. Just 29 bodies have been recovered.
