Sept. 8, 2015: Firefighters stand by a plane that caught fire at McCarren International Airport in Las Vegas.

At least two people were injured after an engine on a London-bound British Airways jet caught fire on a  Las Vegas airport runway Tuesday.

McCarren Airport said the incident involved British Airways flight 2276, which was headed to London’s Gatwick Airport.

Federal Aviation Administration spokesman Ian Gregor says the plane's left engine caught fire Tuesday afternoon while it was preparing for take off. A plume of black smoke could be seen billowing into the sky but firefighters quickly doused the aircraft with fire retardant.

McCarran International Airport spokesman Chris Jones says the 159 passengers and 13 crew members on the British Airways flight had gotten off the plane. The airport reported on its official Twitter account that two passengers were taken to a hospital for minor injuries.

The airport said one runway was taken out of service following the fire. Flight operations continue on the airport’s other three runways.

Clark County Deputy Fire Chief Jon Klassen says the cause of the fire isn't clear yet. He says it didn't appear to breach the cabin.

The Boeing 777-200 was bound for Gatwick Airport near London.
