An immigration hearing is under way for a Cuban exile and former U.S. Central Intelligence Agency (CIA) operative wanted for murder by Venezuela.

The case of Luis Posada Carriles began Monday in El Paso, Texas, where his lawyers are expected to argue against his deportation to Venezuela. Posada Carriles is accused of plotting the 1976 bombing of a Cuban jetliner in which 73 people were killed. He denies involvement.

Lawyers for the 77-year-old man, who was trained by the CIA in the 1960s, argue he could face torture if sent to Venezuela.

Venezuelan authorities say there is no evidence that their government would torture Posada Carriles, and say that the United States is wrongfully protecting an aggravated felon.
