CHICAGO (AP) — Authorities say an American Airlines plane caught fire and passengers evacuated on the runway at Chicago’s O’Hare International Airport.

Federal Aviation Administration spokesman Tony Molinaro says American Airlines Flight 383 departed Chicago for Miami on Friday afternoon when it blew a tire and damaged an engine. Molinaro says the pilot aborted the takeoff and everyone evacuated.

Television reports showed a large plume of black smoke coming from the Boeing 767, which appeared to be damaged at the rear. Evacuation chutes extended from the plane.

Chicago fire officials said on the department’s Twitter account that there was an extra-alarm emergency response at the airport for an “aircraft down.”

As many as nine people were injured, according to unconfirmed reporting on WMAQ-TV. Medical authorities are still trying to access the severity and cause of the injuries.
