Unknown gunmen took five or so shots at the Pentagon this morning—two of which struck windows, but failed to penetrate the reinforced glass. The gunshots were fired around 4:50 a.m. on the south side of the building. Police shut down parts of I-395 as they searched for the gunmen, who are still at large. Over the weekend, several rounds were fired at the National Museum of the Marine Corps and Heritage Center. It’s unknown if the incidents are connected.
