1993 CIA headquarters shooting
On January 25, 1993, outside of CIA Headquarters campus (now known as the George Bush Center for Intelligence) in Langley, Virginia, Pakistani national Mir Aimal Kansi shot and killed two CIA employees in their cars as they were waiting at a stoplight and wounded three others. In a prison interview, Kansi said the shooting was politically motivated: "I was real angry with the policy of the U.S. government in the Middle East, particularly toward the Palestinian people." Kansi fled the country and was placed on the FBI Ten Most Wanted Fugitives list, sparking a four-year international law enforcement search.
