Tornadoes devastate Oklahoma

A series of powerful tornadoes has ripped through northern Oklahoma, leveling homes and injuring at least a dozen people.

Emergency crews are conducting door-to-door searches in hard-hit communities near Enid, where roofs were torn from buildings and utility poles were snapped by the storm.

At least six twisters were confirmed during the multi-day severe weather outbreak that has threatened millions across the Heartland.

Residents reported terrifying scenes as they sought shelter in basements while the storms destroyed entire neighborhoods.
