A passenger jet with 178 people on board has caught fire after developing an engine fault and being forced to divert to Denver.
The American Airlines flight 1006, on a Boeing 737-800, was travelling from Colorado Springs to Dallas Fort Worth when the crew reported engine vibrations, said the Federal Aviation Administration (FAA).
The aircraft diverted to Denver, Colorado and landed safely around 5.15pm (23.15pm UK time).
Images on social media show flames and smoke pouring from one of the engines, along with passengers standing on one of the wings.
The FAA said it would investigate the engine fire, which happened after the aircraft landed at Denver and was taxiing to the gate.
American Airlines said all 172 passengers and six crew on board had been able to exit the plane. Denver International Airport confirmed on X that 12 people were taken to hospital for minor injuries.
The plane is 13 years old, according to flight tracking website FlightRadar24 and is equipped with two CFM56 engines manufactured by CFM International, a joint venture between GE and Safran.
