Deadliest Day: Mass Killings Under Blackout

Under cover of the nationwide internet blackout, security forces carry out mass killings in Tehran, Isfahan, Shiraz, and Kermanshah. Later reporting from Time, The Guardian, and Iran International will estimate between 30,000 and 36,500 killed on January 8-9 combined. January 9 is documented as the single deadliest day, with IRGC and Basij forces using automatic weapons, vehicle-mounted machine guns, and in some reports helicopter gunships against crowds.
