The confirmed death toll from Friday's devastating tornado outbreak rose significantly Monday. Kentucky Governor Andy Beshear announced at least 64 people were killed in his state, which he said suffered "the worst tornado event" in its history.

The governor said it may take weeks before the final death toll would be known. Dozens of people remain unaccounted for. The severe weather and tornadoes affected seven other states, killing at least 12 additional people.

In Kentucky, at least eight people were killed in a candle factory in Mayfield, where more than 100 workers were inside when a tornado struck.
