From the National Security Archives at George Washington University:

Washington D.C. May 18, 2005 - The National Security Archive today posted additional documents that show that the CIA had concrete advance intelligence, as early as June 1976, on plans by Cuban exile terrorist groups to bomb a Cubana airliner. The Archive also posted another document that shows that the FBI's attache in Caracas had multiple contacts with one of the Venezuelans who placed the bomb on the plane, and provided him with a visa to the U.S. five days before the bombing, despite suspicions that he was engaged in terrorist activities at the direction of Luis Posada Carriles.
