At least three persons have been injured after a shooting Wednesday at the gates of the National Security Agency in Fort Meade, Maryland in the suburbs of Washington.

The details of the shooting, which unfolded this morning, are still unclear, but aerial footage showed a black SUV with airbags deployed, apparently after crashing into concrete barriers. A law enforcement dog could be seen searching the car, and one person was reportedly led away in handcuffs.

The NSA said in a tweet that “the situation is under control and there’s no ongoing security or safety threat.” The agency has not responded to a request for more information.

The NSA said the situation was under control.

“The president has been briefed on the shooting at Ft. Meade,” the White House said in a statement. “Our thoughts and prayers are with everyone that has been affected.”

The NSA is the secretive intelligence organisation responsible for global US electronic eavesdropping.
