On 10 June 2014, the Islamic State of Iraq and the Levant (ISIL) killed at least 670 Shia prisoners in an attack on Badush prison. ISIL first separated out the Sunni inmates before executing the remaining prisoners.

On 11 March 2017, the Popular Mobilization Forces announced that they had discovered a mass grave containing the remains of 500 prisoners executed by ISIL in the prison. There were 39 Indian construction workers who were executed in the region.

On 13 June 2021, it was reported that Iraqi authorities had removed the remains of 123 people murdered by ISIL during the prison attack from a mass grave to identify them using DNA from relatives.

New International Investigation and Crime Assessment Report In September 2024, UNITAD (the United Nations Office for the Investigation of International Crimes) published a report on “international crimes” committed by the Islamic State of Iraq and the Levant (ISIL) against prisoners at Badush Central Prison. The report stated that approximately 1,000 male prisoners — mostly Shia but including some Sunnis, Yazidis and Christians — were executed at at least six different locations on the same day (June 10, 2014).UNITAD Publishes Findings on International Crimes Committed by ISIL (Da’esh) against Predominantly Shi’a Inmates of Badush Prison Retrieved 27 November 2025Syrian car bomb attack kills 17 Retrieved 27 November 2025

According to UNITAD and in collaboration with Iraqi civil society organizations — as of the time of this report — the remains of over 600 victims have been recovered and examined. This new finding suggests that the executions were likely more widespread than initially estimated (670 to 1,000+) — and also highlights the possibility of “genocidal intent.” This section can be added to the lead of the article or to a separate section such as “Investigations & International findings.”UNITAD Publishes Findings on International Crimes Committed by ISIL (Da’esh) against Predominantly Shi’a Inmates of Badush Prison Retrieved 27 November 2025
