Police respond to 'ongoing security incident' outside CIA Headquarters in Langley, Virginia

Agents from the FBI have shot a man outside the front gates to the CIA in Langley, Virginia, following a standoff on Monday evening.

Police had originally been called to the headquarters of the agency to deal with what was being described as a ‘security incident.’

The threat by an intruder, was being dealt with by the spy agency’s guard force but then the FBI was also summoned to the scene. 

Initially, security personnel were said to be negotiating with the suspect while they remained in their vehicle, but the standoff then ended with FBI agents shooting the man.

The FBI ‘joined our law enforcement partners at the scene to assist in addressing the situation’, a statement read. 

Agents from the bureau came on scene following a report of suspicious vehicles in the area. 

The person attempted to drive into the CIA grounds without any ID and was quickly stopped by armed guards, who control the opening and closure of access gates to the complex. 

The main CIA buildings are set well back from the nearby roadway. 

Officers from the Fairfax County Police were on site managing traffic around the heavily guarded main entrance to the agency, about 10 miles from Washington D.C.

One law enforcement source told NBC News that CIA security officers were negotiating with the person who remained in their vehicle throughout. 

‘In coordination with our local law enforcement partners, we are addressing a security situation just outside the secure perimeter of CIA Headquarters by our main gate. 

‘Our compound remains secured, and our Security Protective Officers working the incident are the only Agency personnel directly involved’, an agency spokeswoman said earlier on.

The CIA has been the target of attacks in the past.

In 1993, a Pakistani man killed two CIA employees and wounded three others as they sat in their cars outside the main entrance.  

Mir Aimal Kasi was on the run for four years before he was arrested, brought back to the U.S. tried and convicted. He was executed in 2002.

Other high profile sites around the nation’s capital are often on high alert.

In April, a U.S. Capitol police officer was killed and a second was injured after a suspect rammed a barrier.
