Severe weather leaves several dead in parts of U.S.

ST. LOUIS (AP) — Storm systems sweeping across parts of the U.S. Midwest and South have left at least 23 people dead, many of them in Kentucky, where what appeared to be a devastating tornado crumbled buildings and flipped over a car on an interstate.

In Kentucky, some 18 people were killed by severe weather, and the death toll is likely to rise, according to Gov. Andy Beshear. Local authorities in Laurel County, in the state's southeast, said nine people were killed after a tornado touched down.
