But he returned to Iran in 2010 and received a hero’s welcome before being arrested. A U.S. official said in 2010 that Washington had received “useful information” from Amiri. Iran had accused the CIA of kidnapping Amiri. U.S. officials said Amiri had been free to come and go as he pleased, and that he may have returned because of pressures on his family in Iran. Amiri had denied this, saying “my family had no problems”. In a video aired by Iranian state TV in 2010, Amiri said he had fled from U.S. agents. Iran, the United States and five other world powers reached a landmark deal last year, under which Iran agreed to limit its nuclear program in such a way as to ensure it cannot develop nuclear weapons in exchange for a lifting of economic sanctions.
