Iran has carried out a further execution in connection with the January mass protests, according to the Misan news site, which is linked to the judiciary.
Record numbers of people have been executed in connection with the mass protests, monitors say.
Misan reported the man was detained in January near the city of Karaj in northern Iran. He was accused of acting on behalf of Israel, the US and hostile groups, and of working to undermine Iranian national interests and security.
The demonstrations at the start of the year began in response to the nation’s economic crisis and quickly developed into mass protests against the authoritarian leadership. The state responded with a violent crackdown in which thousands of protesters were killed.
Execution over protests as recently as Thursday
The authorities said they had seized a firearm during the man’s arrest, which he allegedly fired during the protests, Misan reported, noting the man denied the charges.
Sunday’s execution comes just days after another on Thursday when another man was put to death likewise in connection with the protests.
Human rights groups have long slammed Iran for its use of the death penalty, accusing the authorities of using the executions as a tool of intimidation. Many face general charges such as espionage, endangering national security or blasphemy.
At least 2,159 people were executed in Iran last year – the highest figure recorded since 1981, according to the human rights organization Amnesty International.
