Young Iranians have taken their protests against the authoritarian regime underground one year on from the death in custody of a 22-year-old woman detained for allegedly wearing the Islamic headscarf incorrectly.
The death of Mahsa Amini on 16 September last year led to the largest wave of popular unrest for years in Iran and a brutal crackdown by security services in response, with hundreds of men, women and children killed and thousands more injured, according to human rights groups.
