An Iranian teenage girl injured weeks ago in a mysterious incident on Tehran’s Metro while not wearing a headscarf has died, state media reported Saturday.

The death of Armita Geravand comes after her being in a coma for weeks in Tehran and after the one-year anniversary of the death of 22-year-old Mahsa Amini which sparked nationwide protests at the time.

Geravand’s Oct. 1 injury and now her death threaten to reignite that popular anger, particularly as women in Tehran and elsewhere still defy Iran’s mandatory headscarf, or hijab, law as a sign of their discontent with Iran’s theocracy.
