A shooting erupted Wednesday outside the headquarters of the US National Security Agency, in the suburbs of Washington, with three persons injured.
NBC News aired aerial images of what appeared to be police surrounding a man on the ground in handcuffs outside the NSA facility in Fort Meade, Maryland.
The NIA is the secretive intelligence organisation responsible for global US electronic eavesdropping.
The local ABC affiliate reported that three persons were injured and a suspect was arrested.
A black SUV appeared to have crashed into a concrete barrier surrounding the site, and bullet holes were visible in the vehicle’s front windows.
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.”
