Up to 100 people may have been killed as tornadoes and storms hit several US states, toppling buildings and trapping people inside.
Elsewhere, at least five people were confirmed to have died, and emergency crews in Illinois are responding to reports of injuries at an Amazon warehouse after the roof collapsed.
Kentucky’s Governor Andy Beshear said the state had “experienced some of the worst tornado damage we’ve seen in a long time.”
He said: “We believe our death toll from this event will exceed 50 Kentuckians and probably end up closer to 70 or 100 lost lives.”
Mr Beshear said four tornadoes had torn through the state.
He said the community of Mayfield had been devastated, with a roof collapse at a candle factory resulting in “mass casualties”.
Almost 60,000 people had been left without power, he added.
Mr Beshear said he had also declared a state of emergency.
