China killed or imprisoned 18 to 20 CIA sources from 2010 to 2012, hobbling U.S. spying operations in a massive intelligence breach whose origin has not been identified, the New York Times reported on Saturday. According to three of the officials, one was shot in front of his colleagues in the courtyard of a government building — a message to others who might have been working for the C.I.A.
Former United States officials report that 18–20 Central Intelligence Agency sources were killed or imprisoned by the Government of China between 2010 and 2012, which significantly hampered the United States Intelligence Community.
