[JURIST] Venezuela delivered evidence [press release] to the US State Department Friday related to Cuban exile Luis Posada Carriles [BBC profile] who is sought by Caracas for allegedly blowing up a Cuban plane as part of a terrorist attack in 1976. The Venezuelan Embassy [official website] in Washington said the documents show "probable cause" that Posada was the mastermind behind the bombing and include an admission by a former employee of Posada, who says he placed a bomb in a toilet of the Cuban plane. Posada was a former CIA agent who vehemently opposes Cuban President Fidel Castro [Wikipedia profile] and escaped from a Venezuelan prison in 1985. He was detained in Miami last month and will go before a US judge in Texas Monday on charges that he illegally entered the US [JURIST report]. Venezuelan President Hugo Chavez [BBC profile] is demanding that Posada be handed over to Venezuela for the bombing trial, which the US has previously refused [JURIST report], while also threatening to reevaluate the country's relationship with the US as Venezuela's biggest importer of oil.
