A monstrous tornado, carving a track that could rival the longest on record, has ripped across the middle of the US in a stormfront that killed dozens across five states.

“I pray that there will be another rescue. I pray that there will be another one or two,” Kentucky governor Andy Beshear said, as crews sifted through the wreckage of a candle factory in Mayfield, where 110 people were working overnight on Friday when the storm hit.
