Iran on Tuesday announced that its Supreme court has passed a death sentence for an Iranian man convicted of spying for the CIA, with Iranian state media alleging that he had shared details of the Islamic Republic's nuclear program with America's Central Intelligence Agency.
Two other alleged spies were given 15-year prison terms but none of their identities has been revealed.
"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 upheld his sentence and you will see it carried out soon," Judiciary spokesman Gholamhossein Esmaili was quoted by the semi-official Fars news agency as saying.
Tensions between Washington and Tehran are especially high at the moment over the assassination of Iranian General Qassem Soleimani, with subsequent attacks on US embassies and outposts in Iraq.
Last summer, Iran said it caught a spy ring of 17 individuals, sentencing some of them to death.
