At least 18 dead after tornado pummels US Midwest, South

Storms that dropped possibly dozens of tornadoes killed at least 18 people in small towns and big cities across the South and Midwest, tearing a path through the Arkansas capital, collapsing the roof of a packed concert venue in Illinois, and leaving people throughout the region bewildered Saturday by the damage.

Confirmed or suspected tornadoes in at least seven states destroyed homes and businesses, splintered trees, and lay waste to neighbourhoods across a swath of the country home to some 85 million people. The dead included seven in Tennessee's McNairy County, four in the small town of Wynne, Arkansas, and three in Sullivan, Indiana.

Other deaths were reported in Alabama, Illinois and Mississippi, along with one near Little Rock, where the mayor said more than 2,000 buildings were in a tornado's path.

Stunned residents of Wynne, a community of about 80 kilometers west of Memphis, Tennessee, woke Saturday to find the high school's roof shredded and its windows blown out. Huge trees lay on the ground, their stumps reduced to nubs. Broken walls, windows and roofs pocked homes and businesses.
