Demonstrators marched in Iran's restive southeast on Friday amid reports on social media that security forces were surrounding a mosque at the centre of weekly anti-government rallies
Anti-government protests have been taking place across Iran since last September's death in custody of 22-year-old Kurdish Iranian woman Mahsa Amini for flouting hijab policy, which requires women to entirely cover their hair and bodies.
"We swear on our comrades' blood to stand strong until the end," hundreds of demonstrators were seen chanting in a video from the flashpoint city of Zahedan posted by the activist news agency HRANA.
