Passengers on an American Airlines flight were evacuated onto the tarmac of a Colorado airport as a fire broke out on the plane, sending smoke billowing into the air.

No injuries were reported in the incident.

Footage of the evacuation online showed passengers huddled on the wing of the commercial airliner, some holding bags, with flames burning near the bottom of the plane.

The US Federal Aviation Administration (FAA) said passengers used inflatable slides to reach the ground safely. The agency said it would investigate the cause of the incident.
