Seemingly every afternoon in Iran's capital, police vans rush to major Tehran squares and intersections to search for women with loose headscarves and those who dare not to wear them at all.

The renewed crackdown comes not quite two years since mass protests over the death Mahsa Amini after she was detained for not wearing a scarf to the authorities' liking. A United Nations panel has found that the 22-year-old died as a result of "physical violence" wrought upon her by the state.
