Pentagon entrances were locked down early Tuesday after a report of possible shots fired near the building.
Major Chris Perrine, a Pentagon spokesman, says a civilian reported he may have heard shots at about 5 a.m. EDT on the south side of the massive Defense Department headquarters.
Perrine says police authorities did a sweep of the area and didn't find anything. The roads and pedestrian entrances leading to the Pentagon were reopened a little after 5:30.
