(CNN)Chinese crews have recovered 431 bodies so far from a cruise ship that capsized last week as a search for the missing continues, state media reported Sunday.
The Eastern Star overturned Monday night in the Yangtze River.
Of the 456 people on board, 14 survived and 11 remain missing, Xinhua news agency reported.
But rescuers have had no luck since Tuesday, the last time two people were pulled out of the water alive.
Massive cranes lifted the overturned ship and righted it Friday. The ship is upright once again, looking almost normal with its bottom resting on the water and its deck and cabins clear above it.
After going through the submerged, capsized ship for three days, rescuers can now walk its decks and open spaces. Since it has been lifted, search crews have gone cabin-by-cabin looking for survivors and bodies in every corner.
The rescue and recovery operation involves nearly 150 other ships, 59 machines, 3,400 Chinese troops and 1,700 paramilitary personnel, state news agency Xinhua said.
And as the search continues, questions remain about what happened.
Authorities took the captain and the chief engineer into custody, but have revealed little about what they have said other than that a tornado hit the ship.
It's unclear why the Eastern Star was the only ship on the busy waterway so badly affected by the storm.
In a statement through a lawyer, the ship's operator, Chongqing Eastern Shipping Corp., apologized to the victims' loved ones, saying the company is cooperating with investigators.
"I have been in deep pain since the start of the incident," said Jiang Zhao, a lawyer for Eastern Star's operator. "I felt extremely sorrowful for all people that perished.
