Arkansas ? A tornado hit parts of Little Rock and its suburbs Thursday, injuring an unknown number of people while damaging businesses and downing trees and power lines.

The National Weather Service, which said a tornado passed directly over its North Little Rock office, reported injuries at a Benton trailer park. An elderly woman was treated by paramedics outside her Cammack Village home.

Meanwhile, at the North Little Rock airport, the storm destroyed a hangar and left several single-engine planes flipped over onto their wings while others were destroyed.

The National Weather Service said the storm damaged a car dealership and a mobile home park near Benton, southwest of Little Rock, and downed power lines and trees farther southwest on I-30. After hitting Little Rock the storm moved into the city’s northeastern suburbs.
