At least 35 people have been killed in the worst unrest in Iran for years. Protests have spread throughout the country after 22-year-old Mahsa Amini was arrested by Iran's morality police for allegedly breaking headscarf rules. Masha Amini eventually died whilst in police custody. Her death resulted in a series of large-scale protests across the country and garnered international attention. The Clerical regime has been in power for four decades and has constantly faced uprisings as it tried to maintain a grip on power. Are we seeing the end of the clerical regime, or will this just be another footnote in Iran's long history?
