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".
The Eastern Star overturned at about 21:30 on Monday evening (13:30 GMT) in the Damazhou section of the Yangtze. It did not send an emergency signal.
The captain - who survived and is now in police custody along with the chief engineer - said it was caught in a cyclone and went down in minutes.
The Eastern Star
- The 76m-long, 2,200 tonne ship was named Dongfangzhixing in Chinese
- It was carrying 405 passengers - mostly elderly tourists but one three-year-old - as well as five travel agency employees and 46 crew members.
- The ship is owned by the Chongqing Eastern Shipping Corporation, and passengers had booked their trip through a travel agency in Shanghai.
- The cruise left the eastern city of Nanjing in April and was travelling to Chongqing in the south-west via the Three Gorges - a journey of at least 1,500km (930 miles).
