The government has described the protests as a plot by Iran's enemies including the United States, accusing armed dissidents - among others - of violence in which at least 20 members of the security forces have been reported killed.In Sanandaj, capital of the northwestern Kurdistan province, one man lay dead in his car while a woman screamed "shameless", according to Hengaw, which said the man had been shot by security forces after he honked his horn as a sign of protest.But videos on social media showed what appeared to be the largest protests in the past three weeks in many Tehran neighbourhoods, including a crowd packing streets in the lower-income southern neighbourhood of Nazi Abad.The Norway-based Iran Human Rights said at least 185 people had been killed in the protests, with the highest number of killings in the restive Sistan-Baluchistan province in the southeast.As state TV showed footage of Ayatollah Khamenei on its main evening news, the broadcast was briefly interrupted in an apparent hack with his image, surrounded by flames, next to pictures of Amini and three other women allegedly killed during the protests."
