The incident occurred shortly after 4 p.m. PDT and involved British Airways flight 2276, which was bound for London’s Gatwick Airport, according to the McCarran International Airport’s Twitter feed.
The Boeing 777 had 159 passengers and 13 crew members aboard at the time.
Photos at one point showed large plumes of smoke rising from the aircraft, though the airport indicated that the fire was put out.
The incident spurred McCarran to close one of its runways, the airport tweeted.
Aerial video showed the aircraft on the tarmac, with several slides coming out of it and fire trucks in the vicinity.
As CNN’s Brian Stelter points out, the emergency evacuation slides don’t deploy until 30 seconds into the video of the incident:
