Protest came before a screening of Holy Spider Photo: Courtesy of Cannes Film Festival
Around 12 women in black attire raised fists and released billows of black smoke as well as unfurling a long scroll of women’s names, believed to be rape victims. Pictures appeared quickly on social media.
The film deals with a journalist who travels to the Iranian city of Mashhad to probe a serial killer Saeed Hanajei, who has been murdering sex workers.
Based on a true story the man said he was on a holy mission to cleanse the streets of sin, according to the film makers.
No group has so far claimed responsibility for the actions. Security personnel allowed the protest to continue but it ended before the film team arrived.
