Two Miami radio hosts say they have fooled Cuban leader Fidel Castro by
     pretending to be President Hugo Chavez of Venezuela in a prank call.

     The two hosts of the radio programme El Vacilon de la Manana (Morning Joker) spliced
     together clips from a Chavez speech and played them to trick Mr Castro into thinking
     he was talking to the Venezuelan leader.

     Then they revealed themselves and called Mr Castro a killer, reportedly prompting a
     tirade of abuse before Mr Castro hung up.

     The radio hosts, Enrique Santos and Joe Ferrero, played the same joke on Mr Chavez
     in January, using a recording of Mr Castro.

     The two Latin American leaders are allies.

     In the latest prank, the DJs pretended to be an aide phoning Mr Castro to ask about a
     suitcase Mr Chavez allegedly lost when the two men were both in Argentina.

     When they got through to a man who listeners say appeared to be the Cuban president,
     they had a brief conversation then told him he had fallen for their prank.

     It has not been possible to confirm that the victim was Mr Castro himself.

     The radio hosts regularly include a slot called "Fidel's on the phone for you" in which
     they try to fool victims with recordings of the Cuban's voice.

     Miami is home to a large Cuban expatriate population, much of it fiercely anti-Castro.

     The Cuban Government has not commented on the prank.
