Henry Kissinger 'cancelled warning against political assassinations'

Henry Kissinger cancelled a warning against carrying out international political assassinations just days before a former Chilean ambassador was killed in Washington, according to a newly released State Department cable.

The declassified document revived questions about Mr Kissinger's role in curbing the secret programme of international assassinations by South American dictators known as Operation Condor.

According to the National Security Archive, a research organisation that uncovered the document, the cable ended efforts by US diplomats to warn the governments of Chile, Uruguay and Argentina against involvement in the covert plan, which targeted political opponents at home and overseas.
