Venezuela is putting pressure on the United States to extradite a Cuban exile accused of a 1976 airliner bombing that killed 73 people.
Venezuela wants to try Luis Posada Carriles (77) for the attack that killed 73 people when the Cuban airliner exploded after departing from Caracas.
US immigration authorities detained him on Tuesday in Miami, where he was living while awaiting a decision on his request for US political asylum.
Vice President Jose Vicente Rangel said the US government would be accused of having a double-standard when it comes to fighting terrorism if it refuses to surrender him to Venezuelan authorities.
"It would be condemned around the world," Rangel said. "It seems that for some there is a good terrorism and a bad terrorism."
Since escaping from a Venezuelan prison in 1985, Posada - who at one point was on the CIA payroll - has spent most of the time moving stealthily from country to country.
Mr Rangel said if extradited, Posada would face justice in Venezuela and would not be sent to Cuba.
US officials have said they would not hand over those suspected of crimes to any country that would then turn them over to the government of Fidel Castro, Chavez's close ally.
But Castro has repeatedly ruled out trying to extradite Posada, saying he should be tried in Venezuela or by an international court.
Mr Rangel called the idea that Posada could be sent to Cuba "an excuse, a subterfuge, that they [the Americans] are using precisely in order to not approve the extradition."
Posada, a naturalised Venezuelan citizen, escaped from a Venezuelan prison in 1985 while awaiting a prosecutor's appeal of his second acquittal in the Cubana Airlines bombing.
Posada has denied involvement in the bombing, but recently declassified CIA and FBI documents quoted informants linking him to planning meetings for the bombing. US documents indicate he was on the CIA's payroll until months before the 1976 bombing.
