Iran has no diplomatic relations with the United States and U.S. interests in Tehran are handled by the Swiss embassy.
Shahram Amiri, a university researcher working for Iran’s Atomic Energy Organisation, disappeared during a pilgrimage to Saudi Arabia a year ago and Tehran accused Riyadh of handing him over to the United States, a charge Saudi Arabia has denied.
Iran’s state television showed on Monday a video of what it said was Amiri. In the footage Amiri said he had been kidnapped and taken to the United States where he was “tortured”.
