A major fuel fire broke out at Miami International Airport late Wednesday night, with fire crews summoned from around the area to fight the flames.

The fire, on the east side of the airport, was graded a second alarm blaze, with smoke and flames visible from nearby roads.

Miami-Dade Fire Rescue spokesman Capt. Eric Baum says the fire was reported around 11 p.m. Wednesday and was brought under control around 1 a.m. Thursday. He says there were no injuries and investigators are now working to determine the fire's cause.

Miami-Dade Fire Rescue dispatch supervisor Eric Dellacatena said about 50 units were called to the scene.

Baum told The Miami Herald that it was “an extremely dangerous operation” that required significant manpower to extinguish.

The fire wasn't near any runways or terminals. Airport spokesman Greg Chin says one flight was delayed for about 45 minutes because of the fire.

Chin says there may be flight delays at the airport Thursday as they work to restore normal fueling operations. He says fueling capacity is expected to be at 40 percent for morning flights.
