ST. LOUIS -- Part of St. Louis Lambert International Airport was evacuated for two hours after the roof caught fire.
No one was injured. Firefighters are working to determine what caused Sunday's blaze.
Officials evacuated the area near where the fire happened. Terminal 1 was closed for about two hours, but Terminal 2 continued operating. Several flights were delayed.
Airport officials say the fire was between the top copper layer of the roof and the structure underneath.
Airport director Rhonda Hamm-Niebruegge praised the efforts of firefighters who had to battle the fire in snowy conditions on a sloped roof.
