CIA admits to losing dozens of informants around the world: NYT
Leading counterintelligence officials issued a memo to all of the CIA’s global stations saying that a concerning number of U.S. informants were being captured and executed.

The CIA’s counterintelligence mission center investigated dozens of incidents in the last few years that involved killings, arrests or compromises of foreign informants. In an unusual move, the message sent via a top secret cable included the specific number of agents killed by other intelligence agencies, according to The New York Times.
