Iran to execute man accused of giving nuclear secrets to CIA
Amir Rahimpour, an Iranian national, was found guilty of transmitting information regarding Iran's nuclear programme to the US intelligence agency.
The judiciary spokesman, Gholam Hossein Ismaili, said Iran's Supreme Court upheld a death sentence against Rahimpour.
"Amir Rahimpour, who was a CIA spy and got big pay out and tried to present part of Iran's nuclear information to the American intelligence service, had been tried and sentenced to death and recently the supreme court [sic] upheld his sentence and you will see it carried out soon," Ismaili told the semi-official FARS news agency.
Ismaili did not provide additional details on Rahimpour's death sentence.
The spokesman's announcement is the latest in a series of hostile interactions between Iran and the US.
Last year, Iran claimed to have dismantled a large-scale CIA cyber-espionage network, which resulted in the arrests of several US operatives in different countries.
Prosecutors later sought the death penalty against the suspects. Many of the defendants were dual citizens, but Iran only recognises national passports.
After the announcement of the alleged spy ring bust, US President Donald Trump dismissed Iran's claims as "totally false".
According to Iran's Human Rights Activists News Agency, Rahimpour is being held in Tehran's infamous Evin prison since last fall.
Evin is notorious for housing political prisoners and human rights abuses
According to the semi-official Iranian Students' News Agency, Ismaili also announced two other detainees - both Iranian charity workers - were sentenced to between ten and five years in prison for alleged espionage on behalf of the CIA. Their names were not announced.
He did not specify whether the prosecuted detainees, including Rahimpour, were apprehended as part of the alleged CIA bust.
