It comes as social media videos appear to show crowds gathered near the capital’s Azadi Square and chanting: “Do not brand me a seditionist. You are the insurgent and oppressor”.
Iran claims to have executed a prisoner seized amid current anti-government demonstrations – the first known execution connected to the upheaval.
People are said to have gathered overnight in Tehran’s Azadi Square, where the execution took place on Thursday.
The prisoner has been named Mohsen Shekari by the country’s judiciary-run news service, Mizan.
According to the semi-official Tasnim news agency, he was accused of wounding a security guard with a machete in Tehran and obstructing a street.
Amnesty International has criticized what it calls “fake trials aimed to scare people who participated in Iran’s popular revolt”
State media released a video of a purported confession by Shekari, in which he appears with a bruise on his right face.
He admitted using a knife to strike a member of the Basij militia and blocking a route with his motorcycle and a companion.
According to rights groups, Shekari was tortured and coerced into confessing his crime.
According to the organization, Iranian authorities are pursuing the death penalty for at least 21 individuals.
The death was criticized by the foreign secretary of the United Kingdom, James Cleverly, who expressed “outrage.”
He wrote on Twitter, “The international community cannot ignore the heinous violence done by the Iranian dictatorship against its people.”
Following the execution of Mahsa Amini, demonstrators continue to take to the streets in defiance of the government and the threat of the security forces.
The Kurdish-Iranian woman, age 22, passed while in the custody of Iran’s morality police.
Social media videos appear to show a throng yelling “Do not brand me a seditionist. You are the insurgent and oppressor “gathering in Tehran on Wednesday evening.
As people celebrated and chanted by the side of the road, the arch of the Azadi Tower Museum is seen in the distance.
According to the activist news agency HRANA, the regime’s response to the protests has been savage repression that has resulted in the deaths of at least 475 protestors.
Academics have criticized Iran’s allegations that its foreign opponents and Kurdish separatists are to blame for the uprising.
This Monday, the sister of Supreme Leader Ayatollah Ali Khamenei denounced the crackdown and demanded that the Revolutionary Guards lay down their arms.
