One commercial airliner bumped into another Sunday morning at Minneapolis-St. Paul International Airport, an official said.

The incident occurred about 6 a.m. when a Spirit Airlines Airbus A320 heading to Chicago was being backed away from the Concourse E gate and ran into a smaller United Airlines jetliner that was parked, said airport spokesman Patrick Hogan.

Both planes were damaged, but no injuries were reported, Hogan said.

The United Bombardier CRJ700 aircraft had no crew, airport employees or passengers, he said. A United spokeswoman said the plane needed to be repaired., a commercial airlines tracking website, reports that the Spirit flight was canceled. Messages have been left with a Spirit spokesman for information about the incident.

There were delays to other flights in connection with the incident, one passenger at the airport reported.

The Federal Aviation Administration is investigating.
