Iranians have been protesting in the streets since the death in custody on 16th September of Mahsa Amini, a 22-year-old woman who was arrested by morality police for the crime of failing to cover every last strand of her hair. Unlike previous protest movements in Iran the momentum of this uprising doesn’t appear to be diminishing. In this film, an Iranian women’s rights activist and The Economist’s Middle East correspondent outline what needs to happen for the protests to achieve their aim of toppling the regime.
