Hopes are fading of any more survivors being found inside a cruise ship which capsized on China's Yangtze River.

The Eastern Star, with 456 mostly elderly people on board, overturned in bad weather on Monday night.

Eighteen people are now confirmed to have died, says state media, and 14 have been rescued - some had been trapped in air pockets inside the hull.

Officials say they will keep looking for survivors, but it could be China's worst maritime disaster in decades.

"As long as there's even a little hope, we will give it 100% and will absolutely not give up," Transport Minister Yang Chuantang said on Tuesday. But he said rescuers were in "a race against time".
