Iran captured 17 spies working for the US Central Intelligence Agency (CIA) and some have been sentenced to death, Iranian media reported on Monday (July 22).
Iranian state television published images it said showed the CIA officers who were in touch with the suspected spies.
There was no immediate comment on the Iranian allegations by the CIA or U.S. officials.
Iran announced in June that it had broken up an alleged CIA spy ring but it was unclear whether Monday's announcement was linked to the same case.
The announcement comes after three months of spiraling confrontation between Iran and the West that began when new tighter US sanctions took effect in May.
