Iranian security forces launched a massive crackdown on nationwide protests that had spread to all 31 provinces, killing thousands in what became the deadliest massacre in modern Iranian history. Some observers described it as "Iran's Babi Yar" given its tremendous scale. Supreme Leader Ali Khamenei ordered forces "to crush the protests by any means necessary," with Ali Larijani, Secretary of the Supreme National Security Council, identified as the mastermind of the massacres.
Death toll estimates ranged from 3,117 to over 36,500, with Time reporting 30,304 protest-related deaths registered in civilian hospitals on January 8-9 alone. According to doctors inside the country cited by The Sunday Times, at least 16,500 protesters were killed and 330,000 injured. Hospitals in Tehran and Shiraz were overwhelmed by injured protesters, many with gunshot wounds.
The protests began December 28, 2025, initially over inflation, food prices, and currency depreciation, but quickly evolved into demands for regime change. By January 9, millions had taken to the streets in Iran's largest protests since the 2022 Mahsa Amini uprising. Iranian authorities imposed an internet blackout on January 8 to hide the scale of atrocities.
Trump warned on January 4 that the U.S. could intervene if Iranian authorities escalated violence, saying Iran would be "hit very hard." Khamenei acknowledged "thousands of people" had been killed, blaming Trump and calling all protesters "terrorists affiliated with the US and Israeli governments." The UN Human Rights Council ordered an urgent investigation into what officials called the deadliest crackdown since the 1979 revolution.
