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.
The Washington police chief said there could be as many as two other shooters at large. She said officers were on the lookout for two men, one white and one black, both in military-style uniforms.
President Barack Obama said the rampage targeted patriots, military and civilian alike, "men and women who were going to work, doing their job, protecting all of us."
Terrie Durham, who works at the Naval Sea Systems Command building, said she saw a gunman who 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."
