WASHINGTON (Reuters) – 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.
Investigators remain divided over whether there was a spy within the Central Intelligence Agency who betrayed the sources or whether the Chinese hacked the CIA’s covert communications system, the newspaper reported, citing current and former U.S. officials.
The Chinese killed at least a dozen people providing information to the CIA from 2010 through 2012, dismantling a network that was years in the making, the newspaper reported.
The breach was considered particularly damaging, with the number of assets lost rivaling those in the Soviet Union and Russia who perished after information passed to Moscow by spies Aldrich Ames and Robert Hanssen, the report said. Ames was active as a spy in the 1980s and Hanssen from 1979 to 2001.
