JFK file release: Mob hits on Castro, threat on Oswald

The CIA mulled mafia hits on Cuban President Fidel Castro. Someone called the FBI threatening to kill Lee Harvey Oswald a day before Oswald's murder. And the US examined sabotaging airplane parts heading to Cuba.

These assertions are some of many unearthed in newly revealed government documents related to the assassination of President John F. Kennedy. 

Following a deadline 25 years in the making, the National Archives on Thursday evening released a horde of JFK files.

President Donald Trump blocked the release of some documents at least temporarily, citing national security concerns, leaving researchers, conspiracy theorists and interested onlookers 52 previously unreleased full documents and thousands in part to sift through.
