JIANLI, China - Chinese officials and rescuers bowed in mourning towards a battered cruise ship which capsized during a storm in the Yangtze River, as the death toll from the disaster reached 431 on Sunday, with 11 still missing.

Only 14 survivors, one of them the captain, have been found after the ship carrying 456 overturned in a freak tornado on Monday night in Jianli in Hubei province. Most of the passengers were elderly tourists.

The four-storied ship was righted and raised on Friday, allowing rescuers onto it to clear away debris, break down cabin doors and look for the remaining missing. The river is being swept to as far away as Shanghai looking for the missing.

Government spokesman Hu Kaihong told reporters that DNA tests were being carried out to identify the bodies. Local police have collected DNA samples from 412 bodies, according to Guo Tangying, deputy head of the Hubei provincial police department.

Sunday marks seven days since the Eastern Star went down, and according to Chinese tradition this a key date on which to mourn the dead.

State television showed hundreds of rescue workers and government officials standing on the deck of a barge facing the Eastern Star during a three-minute silent tribute to the victims at around 9 am Sunday. They removed their hats and bowed their heads, as surrounding boats sounded their horns.

Families members will also gather near the river for ceremonies.
