What does the news item say about Amiri? [originaltext] Officials here are sa

Officials here are saying nothing about Amiri’s activities or where he has been since he disappeared while on a religious pilgrimage in Saudi Arabia during June of last year. But they insist that he has been in the United States on his own free will, has not been mistreated, and is free to return to his homeland whenever he wants.
    The comments followed an Iranian announcement that Amiri, a 32-year-old nuclear scientist, had entered the Iranian office in Washington, officially part of the Pakistani embassy, and asked for his immediate return to Iran.
    But Amiri purportedly has given conflicting accounts in videos appearing on the Internet in recent weeks. In one, he allegedly said he was kidnapped by US agents, in another he purportedly said he had escaped from US intelligence, and in a third that he was free and safe and studying in the United States.
    The US broadcast network ABC reported earlier this year that Amiri had defected and provided information on Iran’s nuclear program, which US officials say has a weapons component. Secretary of State Hillary Clinton said Amiri is free to leave the United States, and contrasted his case with three American hikers who have been jailed in Iran since straying into the country from northern Iraq last year.
