"An Iranian nuclear scientist, who Tehran claims was kidnapped by U.S. agents, arrived in his homeland early Thursday, state-run media reported. Shahram Amiri arrived at Tehran's Imam Khomeini Airport and was greeted by Deputy Foreign Minister Hassan Qashqavi, according to the Islamic Republic News Agency. Upon arrival, Amiri, who is a researcher from Tehran's Malek Ashtar University, repeated his claim that he was kidnapped by U.S. intelligence agents while on a religious pilgrimage to Saudi Arabia in June 2009. ""I was abducted in Medina ... Then I was transferred to an unknown location in Saudi Arabia,"" Amiri told Press TV. ""They injected anesthetic drugs into me. They took me to the United States on a military plane. ""During my stay in the first two months, I was subjected to heavy psychological and mental tortures by CIA interrogators,"" he said. ""Other kinds of pressure too. They told me if I don't cooperate with them, they will hand me over to Israel and there are hidden prisons in Israel and there will be no trace of you any more."""
