Navy Yard Shooting: A History of the Yard
An active shooting is underway at Washington D.C.'s Navy Yard Monday morning. At least one police officer and three others are confirmed as shot, according to the MPD. The Navy confirmed that an active shooter was inside the Naval Sea Systems Command Headquarters building at 8:20 AM, and a shelter in place order was issued for personnel.
Much of Washington D.C. has been shut down as the search for the shooter goes on. Schools and businesses in the area are on lockdown. All flights have been grounded at Ronald Reagan National Airport, according to CNN.
The White House says that President Obama has been briefed "several times" this morning about the situation.
We'll continue to update this post as more comes in.
Here's what you need to know about the Yard itself:
The Naval Sea Systems Command is the largest of the Navy's commands, with a fiscal year budget of almost $30 billion. About 3,000 people work in the headquarters.
The Navy Yard, which is a national historic landmark, was for decades known as a "ceremonial gateway" to D.C.
Purchased in 1798, the Washington Navy Yard was established in October 1799 and built under the direction of the first secretary of the Navy.
The yard has a firm place in U.S. history: In 1865, the Lincoln assassination conspirators were brought there after they were captured; including the body of John Wilkes Booth.
The Navy Yard was ordered burned as the British marched on Washington during the War of 1812 to prevent its capture.
Weapons designed and built at the yard were used in every U.S. war until the 1960s.
