ST. LOUIS (AP) — Storm systems sweeping across the Midwest have left at least 21 dead, including nine people killed after a tornado sparked what authorities called a mass casualty event in southeastern Kentucky.

In Kentucky, some 14 people have been killed by severe weather — including a devastating tornado — in Kentucky, and the death toll is likely to rise, according to Gov. Andy Beshear.

“Kentucky, we’re starting today with the tough news that we lost at least 14 of our people to last night’s storms, but sadly, this number is expected to grow as we receive more information. Please pray for all of our affected families,” Beshear said Saturday in a post on social media platform X.

Earlier, authorities in Laurel County said nine people were killed after a tornado touched down in southeastern Kentucky.

Kentucky authorities said there were also severe injuries when a twister tore across Laurel County late Friday, causing structures to crumble and even flipping over a car on I-75.
