Ana Montes who is among the best-known Cold War spies caught by the US has been released from prison after more than 20 years in custody.
The 65-year-old spent almost two decades spying for Cuba while employed as an analyst at the Defence Intelligence Agency.
After her arrest in 2001, officials said she had almost entirely exposed US intelligence operations on the island.
Michelle Van Cleave, who was head of counter-intelligence under President George W Bush, told Congress in 2012 that Montes had compromised everything - virtually everything - that they knew about Cuba and how they operated in Cuba.
