PITTSBURGH (KDKA) – Pittsburgh International Airport has reopened and cleared one of its terminals after finding a smoking satchel.

Smoke was initially reported at the airport around 7:30 a.m., near gate D80 Thursday morning.

Firefighters were called to the scene, but by the time they responded, the smoke had dissipated.

Within an hour, firefighters found the source of the smoke in a men’s bathroom plumbing access panel.

Responders found a black satchel and charring around the panel.

Airport officials say the smoke was caused by a cigarette butt that caught fire to some paper towels.

The Allegheny County Bomb Squad and county fire marshals were also called to the scene.

Flights on Delta, American and United airlines were affected and authorities temporarily moved flights from Concourse D to Concourse A.

Concourse D has been reopened the public and airlines as of 11 a.m.
