Iran’s President has vowed to take action against protesters after more than a week of anti-government demonstrations.
President Ebrahim Raisi pledged to “deal decisively” with the protests, which have now spread to most of Iran’s 31 provinces.
Officials say some 35 people have been killed since protests broke out over the death of a woman in police custody.
Mahsa Amini died after being detained for allegedly breaking headscarf rules.
Officers reportedly beat Ms Amini’s head with a baton and banged her head against one of their vehicles. The police have said there is no evidence of any mistreatment and that she suffered “sudden heart failure”.
Videos circulating on social media have captured violent unrest in dozens of cities across the country, with some showing security forces firing what appeared to be live ammunition on protesters in the north-western cities of Piranshahr, Mahabad and Urmia.
Amnesty International has warned that evidence it gathered pointed to “a harrowing pattern of Iranian security forces deliberately and unlawfully firing live ammunition at protesters”.
