Iranian security forces used excessive and unlawful lethal force against protesters in the western city of Sanandaj, the capital of Iran's Kurdistan Province, in October and November, Human Rights Watch (HRW) said on December 21, urging the United Nations to investigate such abuses. “The Iranian authorities have unleashed alarming violence against protesters in Sanandaj since September,” said HRW's Tara Sepehri Far. The protests were triggered by the September death of 22-year-old Iranian Kurdish woman Mahsa Amini in police custody.
