A man brandishing an assault rifle, shotgun and handgun opened fire Monday inside a building at the Washington Navy Yard — killing at least four people and wounding at least seven more, including two police officers, authorities said.
SWAT officers swarmed the building, the headquarters of the Naval Sea Systems Command, and a shooter there was killed, sources told NBC News.
More than two hours after the first gunfire, there were reports that tactical teams were entering a second building at the Navy Yard, but there was no hard evidence of a second gunman.
Terrie Durham, who works at the Naval Sea Systems Command building, said the gunman appeared to be wearing dark fatigues. Another worker there, Todd Brundidge, said he heard a fire alarm go off, and later saw the gunman come around the corner.
“He turned our way and started firing, and we ran downstairs to get out of the building,” Brundidge said. “No words. He raised the gun and started firing.”
A naval security guard was among those shot and was hit in both legs, U.S. military officials said. Washington city police told WRC, the NBC affiliate in Washington, that one of their officers was also among those shot. It was not clear how many of the others shot were civilian and how many were military.
