Iran’s department of judiciary has announced that the death sentence for a person convicted of spying for the U.S. Central Intelligence Agency (CIA) has been confirmed.

Iran’s official government news agency IRNA quoted Gholam-Hossein Esmaili, the spokesman of the Judiciary on February 4 that Amir Rahimpour who was “unmasked, tried and convicted of passing on “nuclear information” to the CIA had received the death penalty ad the sentence was confirmed.

The spokesman added that Rahimpour had received large sums of money, while cooperating with the U.S. spy agency, but he did not disclose any more details about the case.

Iran’s judicial system often works in secret without due process of law on issues of national security, even when dissidents are accused of security-related crimes. This is the first time officials in Iran make a reference to Rahimpour’s case.

The only reference to the case came last year from HRANA, an Iranian human rights group based abroad. A news release by the group said at the time that a suspect with a graduate degree in electric engineering was being kept in Tehran’s Evin prison, accused of cooperation with the United States.

Esmaili also told reporters that two other individuals have been tried on charges of cooperating with the CIA and sentenced to ten and five years each, but refused to disclose their identities.
