CIA conspired with mafia to kill Castro

The disclosure is contained in a 702-page CIA dossier known as the "Family Jewels" compiled at the behest of then agency director James Schlesinger in 1973. According to a memo written at the time, the purpose of the dossier was to identify all current and past CIA activities that "conflict with the provisions of the National Security Act of 1947" - and were, in other words, illegal.

The dossier covers operations including domestic surveillance, kidnapping, infiltration of anti-war movements, and the bugging of leading journalists.
But its detailed information on assassination attempts against foreign leaders is likely to attract most attention.
