Iran has carried out its second public execution in response to a nearly three-month wave of anti-government demonstrations.
Majid Reza Rahnavard was hanged in Mashhad, according to the country’s judiciary.
He was found guilty of stabbing and killing two security personnel.
Last Thursday, the first execution linked to the protests took place, with Mohsen Shekari being hanged, prompting widespread condemnation.
At the time, UK Foreign Secretary James Cleverly warned that the world could not “turn a blind eye to the abhorrent violence committed by the Iranian regime against its own people.”
The current protests are in response to the death of Mahsa Amini, a 22-year-old woman who was arrested by the country’s morality police in September and died in custody.
She was held for allegedly wearing her hijab, or headscarf, “improperly”.
The unrest, which began in the capital Tehran where Ms Amini died, has spread to some 160 cities in all of Iran’s 31 provinces.
It is considered one of the most serious challenges to the Islamic Republic since the 1979 revolution.
