The plea came after former Romanian President Ion Iliescu revealed on Tuesday that he had approved CIA requests to set up at least one secret prison in Romania, where prisoners were subject to torture. Iliescu admitted that he deeply regretted that decision.
"We still believe that the authorities have an obligation to conduct an effective investigation, which they have not done so far," Maria-Nicoleta Andreescu said.
Andreescu also said that no conclusions should be made before the investigation is completed despite the gravity of former President Iliescu's revelations.
She stressed that Poland, Lithuania and now Romania are all known to have hosted US secret detention facilities used by the CIA in the so-called War on Terror, initiated by the United States following the September 11, 2011 attacks.
