MINNEAPOLIS -- Officials say a Delta Air Lines plane clipped wings with a smaller jet as the two were preparing to take off from Minneapolis-St. Paul International Airport.

An airport spokesman says no one was hurt in Wednesday night's incident, which happened shortly after 8 p.m.

The Delta Boeing 757 was bound for Los Angeles. The smaller Embraer jet, flown by the Delta feeder Compass Airlines, was bound for Louisville, Kentucky. Both returned to their gates with wing damage.

The cause of the collision wasn't immediately known.

Federal Aviation Administration spokesman Tony Molinaro says the planes collided as the Delta flight was taxiing for departure and the Compass flight was pushing back from the gate. The FAA is investigating.

Delta released a statement saying it is also investigating.
