CIA headquarters shooting Virginia police.

Authorities say a security incident outside CIA headquarters has led to a shooting. Officers with the Fairfax County Police Department in Virginia responded to what they described as a “nonfatal” shooting at the agency’s headquarters in McLean about 4 a.m. Thursday to assist CIA police with traffic control. The FBI says there is no ongoing threat to public safety and declined to respond when asked whether authorities have identified a motive for the incident. CIA headquarters is in McLean, Virginia, just outside Washington.
