ORLANDO, Fla. (AP) - Passengers have been evacuated from an Allegiant Air jet at Orlando-Sanford International Airport after the plane's right engine caught fire.

The Federal Aviation Administration says Flight 700 was still at the gate Friday morning when the fire occurred. It was quickly extinguished and there were no reports of injuries.

Passengers were evacuated using the jetway.

The MD-80 aircraft was scheduled to depart to Roanoke, Va. An Allegiant Air spokeswoman said 142 passengers were onboard and will be placed on the next flight.

The cause of the fire remains under investigation.
