Iranian rights activists have urged women to publicly remove their veils on "National Day of Hijab and Chastity" on Tuesday, risking arrest for defying the Islamic dress code as the country's hardline rulers crack down on "immoral behaviour".
Under Iran's Islamic Sharia law, imposed after the 1979 revolution, women are obliged to cover their hair and wear long, loose-fitting clothes to disguise their figures. Violators face public rebuke, fines or arrest.
