A gunman shot at least seven people, including two police officers, on Monday at a Navy facility in Washington, authorities said. Naval officials said that the gunman was on the loose.

A naval security guard was among those shot and was seriously wounded, 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 five others shot were civilian and how many were military.

Tim Hogan, a spokesman for Rep. Steven Horsford of Nevada, posted photos to his Twitter account of people tending to at least one person down on a street corner.

The Navy said on its Twitter feed that three shots were fired at 8:20 a.m. ET at the headquarters of the Naval Sea Systems Command, part of the Washington Navy Yard. Almost an hour later, the Navy still characterized the shooter as “active.” SWAT teams swarmed the Naval Sea Systems Command building and were hunting for the gunman.
