In military terminology, a black site is a location at which an unacknowledged black project is conducted. Recently, the term has gained notoriety in describing secret prisons operated by the United States Central Intelligence Agency (CIA), generally outside of U.S. territory and legal jurisdiction.[citation needed] It can refer to the facilities that are controlled by the CIA used by the U.S. government in its "War on Terror" to detain alleged unlawful enemy combatants.
