(BBC) A Cuban special investigator is testifying in the perjury trial of a former CIA agent in Texas.
The evidence is a rare example of cooperation between the US and Cuba.
In all, two security officers and a medical examiner from Cuba are expected to testify in the US government case against Cuban native Luis Posada Carriles.
He spent a lifetime using violence to destabilize communist political systems throughout Latin America, backed by Washington.
Mr Posada, 82, is not on trial for the bombings, including that of a Cuban airline off Barbados in 1976 – only for lying about them at his immigration hearings.
He remains a hated figure in Cuba, where authorities have been more than willing to cooperate in the case against him.
Cuba and Venezuela would like to try him for a number of attacks but a US judge has ruled Mr Posada can’t be sent to either country for fear he could be tortured.
