A parking garage fire at Newark Liberty International Airport damaged at least 17 vehicles Thursday morning.

Authorities say the fire began shortly before 7 a.m. Thursday on the rooftop of the garage for the airport's Terminal C.

The fire sent flames and heavy black smoke spewing into the air. The Newark Fire Department says the fire was brought under control shortly before 8 a.m.

The Port Authority of New York and New Jersey, which operates the airport, says other airport operations weren't affected.

Returning passengers who parked in the deck were told that they needed to be driven up the ramp to get to their vehicles for their own safety. Frigid temperatures Thursday created icy conditions due to the water from the firefighting effort.

The Newark Fire Department is investigating the cause of the blaze. No injuries have been reported.
