More than 500 people have reportedly been killed during ongoing protests in Iran, according to an independent rights group. The demonstrations, sparked by economic grievances, have escalated into a significant challenge to the country's leadership, with widespread crackdowns and a nationwide blackout. Iranian authorities have threatened severe punishments for protesters, while the president accused foreign-linked 'terrorists' of inciting violence but also expressed willingness to address citizens' concerns. Tensions have risen internationally, with the United States and Israel discussing possible intervention and Iranian officials warning of retaliation against foreign attacks.
