(CBS News) POMONA, N.J. - Firefighters are battling a two-alarm blaze at a Federal Aviation Administration technical building which prompted the temporary closure of Atlantic City International Airport.
Officials tell CBS News that the fire began at about 12:10 p.m. in building 316, possibly on the roof where construction crews were working. The flames quickly spread to the adjoining headquarters building.
The airport was temporarily closed for precautionary measures.
National security correspondent Bob Orr reports that FAA emergency crews responded, as did fire and rescue crews from the adjacent Airport, and at 1:45 p.m. the fire was reported to be "nearly under control."
Orr says the airport has reopened and is operating normally.
The cause of the fire has not been established and it's unclear how much damage has been done. It was described as "a large fire," and pictures on Twitter seem to verify that.
Employees have been evacuated and there are no reports of injuries, but officials caution that these are preliminary reports.
The FAA center in Atlantic City is used for research, development and testing for FAA security systems. The Federal Air Marshals also have a training center on the campus.
