Orlando Bosch Ávila (18 August 1926 – 27 April 2011) was a Cuban exile, former Central Intelligence Agency-backed operative, and head of Coordination of United Revolutionary Organizations, which the FBI has described as "an anti-Castro terrorist umbrella organization". Former U.S. Attorney General Dick Thornburgh called Bosch an "unrepentant terrorist". He was accused of taking part in Operation Condor and several terrorist attacks, including bombing of a Cuban civilian airliner on 6 October 1976 in which all 73 people on board were killed, including many young members of a Cuban fencing team and five North Koreans. The bombing is alleged to have been plotted at a 1976 meeting in Washington, D.C. attended by Bosch, Luis Posada Carriles, and DINA agent Michael Townley. At the same meeting, the assassination of Chilean former minister Orlando Letelier is alleged to have been plotted. Bosch was given safe haven within the US in 1990 by President George H. W. Bush, who in 1976 as head of the CIA had declined an offer by Costa Rica to extradite Bosch.
Bosch was born on 18 August 1926 in the village of Potrerillo, 150 miles east of Havana. "Bosch's father was first a policeman in Potrerillo and later a successful restaurant owner in the same village. His mother was a teacher." In 1946 Bosch enrolled in the University of Havana medical school, where he first met Fidel Castro; Bosch was president of the medical school student body while Castro was head of the law school student body. After graduating, Bosch moved to Toledo, Ohio for a paediatric internship.
