At least 70 people killed as tornadoes rip through US Midwest

The governor of Kentucky says he fears 70 to 100 people may have been killed and many more injured, after a devastating series of tornadoes ripped through the Midwest and parts of the South.

At least 18 tornadoes were reported across several states, with an emergency declared in Kentucky after a factory there collapsed, killing dozens inside.

Tornado damage and deaths were also reported in Arkansas, Tennessee, Missouri and Illinois where workers were trapped in an Amazon warehouse after it was hit.
