Storms kill 20 across US including nine dead in ‘mass casualty event’ in Kentucky

Storms also killed seven in Missouri, spawned tornadoes in Wisconsin and brought a heatwave to Texas

Storm systems sweeping across the midwestern US have left more than 20 dead in Missouri and Kentucky.

Kentucky’s governor, Andy Beshear, said 14 of the dead were in his state. At least nine of those deaths were reported after a tornado sparked what authorities called a mass casualty event in south-eastern Kentucky.
