Only one of the 12 trapped miners found in a US coal mine on Wednesday has survived, reports from the US say.
CNN said only one man - critically ill and rushed to hospital - had been found alive by rescuers, just hours after news all had been found safe.
CNN named the survivor as 26-year-old Randal McCloy.
Relatives had celebrated in churches after reports that the rescue attempts had found all 12 men alive in an air pocket in the mine.
"Everybody is stunned," said Sam Lands, the brother-in-law of Martin Bennet, who had been in the mine.
"I thought I was going to pass out. I couldn't believe it. We've been lied to all along. We need answers."
West Virginia Governer Joe Manchin had earlier praised news of the men's rescue from the Sago mine a "miracle".
Earlier, rescuers had found the body of a 13th miner left in a mine cart some 3000 metres inside the mine.
The men had been trapped in the mine after an explosion on Monday. The cause of the blast is not yet known.
