According to the official Iranian news agency IRIB, an Iranian was executed on Monday for allegedly spying on US and Israeli intelligence agencies.
Last month, the judiciary said that Mahmoud Mousavi-Majd, who was arrested in 2018, had spied on the former Revolutionary Guard commander Qassem Soleimani. However, the case was not linked to the murder of Soleimani earlier this year.
On January 3, a US drone attack in Iraq killed Soleimani, leader of the Quds Force of the Revolutionary Guard.
Washington had accused Soleimani of carrying out attacks by Iranian-style militias on US forces in the region.
The execution occurs at a time when millions of Iranians have protested on social media to protest the death sentences handed down to three men accused of taking part in protests against the government last November.
Her executions have been suspended, one of her lawyers, Babak Paknia, said on Sunday.
Human rights activists said the sentences for the three men are aimed at intimidating future demonstrators.
Witnesses said security forces fired tear gas last Thursday to disperse protesters in the southwestern city of Behbahan who protested economic problems but also the death sentences against the three men.
The Farsi hashtag "Do Not Run" was tweeted millions of times last week.
