At least 18 people died in Kentucky, seven in Missouri and two in Virginia, authorities say, as severe weather including tornadoes and hail sweeps the U.S.

Kentucky Gov. Andy Beshear announced Saturday that 18 of the deaths came in his state, and 10 others were hospitalized in critical condition after a severe storm system swept across part of the U.S. Midwest and South.

An unstable spring weather system spawned tornadoes overnight in the U.S. Midwest and Ohio River Valley, killing at least 25 people in Kentucky and Missouri and causing widespread damage to homes and property,
