The move is aimed at "preventing resistance against the hijab law," police say. A growing number of Iranian women have removed their veils since the death of a 22-year-old Kurdish woman in the custody of the moral police.

Videos of veilless women resisting morality policing have flooded social media. Under Iran's Islamic sharia law, women are required to cover their hair and wear long, loose-fitting clothes to disguise their figure. The Interior Ministry said on March 30 that there would be no turning back on the issue.
