Widespread protests continue to erupt in Iran following the Sept. 16 death of Mahsa Amini, a 22-year-old woman who was beaten fatally by Iran’s morality police after being arrested on charges of wearing clothing that violated a strict Islamic dress code.

The protests, which swiftly spread from Amini’s hometown to more than 80 cities, now pose the biggest challenge to the clerical regime’s harsh repression since the 2009 wave of protests sparked by the rigged reelection of Mahmoud Ahmadinejad, then Iran’s president.
