At least 22 people have been killed as a powerful storm whipped up tornadoes on its third day across parts of the southern, central and eastern United States. Local media reports, at least five people were killed as tornadoes left a trail of destruction in North Carolina yesterday. One person was killed in Alabama's Marengo County while six more died in Autauga and Washington Counties. Reports of deaths have also come in from several other places in the region. The storm toppled trees and power lines, tore roofs off houses and scattered tractor-trailers across highways. The National Weather Service said in Chicago, two dozen tornadoes were reported in the southern states of Mississippi and Alabama on Friday, a day after 15 twisters struck in Oklahoma, Kansas and Texas.
