It is one of history’s most enduring mysteries and has kept conspiracy theorists buzzing for half a century: did Fidel Castro have a hand in the assassination of President John F Kennedy?
Officially, the Cuban dictator was cleared of involvement in the shooting of his fiercest adversary. The inquiry into the murder concluded that Lee Harvey Oswald, a communist sympathiser, acted alone.
Now a retired CIA officer claims to have proof that Castro knew the murder was about to happen – an allegation certain to refuel speculation before next year’s 50th anniversary of a pivotal moment of the 20th century.
