ST. LOUIS — St. Louis’ main airport was closed for business Saturday while crews cleaned up after an apparent tornado tore through a terminal, causing several injuries and sending people scurrying for shelter as plated glass shattered around them.

Friday evening’s storm at Lambert-St. Louis International Airport ripped away a large section of the main terminal’s roof, forcing the airport to close indefinitely and diverting incoming flights to other cities.

Elsewhere around St. Louis, residents in suburbs were waking to damaged homes, fallen trees and downed power lines — the remains of a fierce line of storms that moved through central and eastern Missouri.

Only four people with minor injuries were taken to the hospital from Lambert, while an unspecified number of others were treated at the scene for cuts blamed on flying glass.

“We’re fortunate we didn’t have larger (numbers) of injuries,” said airport director Rhonda Hamm-Niebruegge.

The airport’s main terminal sustained the most damage. Hamm-Niebruegge said roughly half of that structure’s windows were blown out, sending glass and rain into that building. Elsewhere on the property, trees were toppled and power lines downed, further limiting access to the airport even hours after the storm left its destruction.
