Iran's protests may have subsided, but women have found new ways to defy the country's regime.

A young woman walks down a street in Tehran, her hair uncovered, her jeans ripped, a bit of midriff exposed to the hot Iranian sun. An unmarried couple walk hand in hand. A woman holds her head high when asked by Iran's once-feared morality police to put a hijab on, and tells them: "Screw you!"

These acts of bold rebellion - described to me by several people in Tehran over the past month - would have been almost unthinkable to Iranians this time last year. But that was before the death in the morality police's custody of 22-year-old Mahsa Amini, who had been accused of not wearing her hijab [veil] properly.

The mass protests that shook Iran after her death subsided after a few months in the face of a brutal crackdown, but the anger that fuelled them has not been extinguished. Women have just had to find new ways to defy the regime.

A Western diplomat in Tehran estimates that across the country, an average of about 20% of women are now breaking the laws of the Islamic Republic by going out on to the streets without the veil.
