At least 522 people have been killed in four months of anti-government protests in Iran, said a report issued on January 15 by the U.S.-based Human Rights Activists News Agency (HRANA). Among the dead are 70 minors and 68 security forces, the agency reported. Nearly 20,000 people had been arrested, 110 on charges that could lead to a death sentence, it said. Four have been executed. Protests were triggered by the death in custody of Mahsa Amini, 22, an Iranian Kurdish woman who was arrested by morality police for allegedly not complying with Islamic dress codes.
