The ambassador (Hassan Kazemi Qomi) says the recent release of two Iranians from Iraqi custody is not an indication of any impeding deal to free the Americans.
The diplomat tells The Associated Press the fate of the Americans is in the hands of Iran's judiciary.
The detained Americans were arrested along the Iraqi border last July. Iran has accused them of espionage. But their families say the three were hiking in northern Iraq's Kurdish region, and if they strayed into Iran, it was unintentional.
