Someone fired shots at the Pentagon early Tuesday, hitting the building and causing minor damage, defense officials said.
Police who protect the massive Defense Department headquarters in Washington, D.C., temporarily locked down some road and pedestrian entrances to the building after a civilian reported he may have heard shots at about 5 a.m. on the south side of the facility.
A sweep of the area and facility found that some shots had hit the building, said Marine Col. Dave Lapan, a Pentagon spokesman. He didn't know how many or from what kind of weapon.
Roads and pedestrian entrances leading to the Pentagon were reopened a little after 5:30 a.m., but part of nearby highway 395 was closed temporarily later for part of the investigation.
A dozen police also were seen at around 9 a.m. walking side-by-side in a line as they combed through a grassy area on the south side of the building.
Lapan said there were no injuries, but he did not elaborate on whether there were any suspects.
