Iran protests: how far can they go?
On an early autumn day in Tehran, the morality police arrested in a city park a 22-year-old Iranian woman who was in the capital on a family visit, bundled her into a van and drove her to the police station.
The detention of Mahsa Amini on September 13 set in motion a chain of events that one month on has left Iran’s clerical leadership under supreme leader Ayatollah Ali Khamenei, 83, facing one of its biggest challenges since the 1979 Islamic Revolution but whose final outcome remains far from certain.
