On 15 September 2022, following the recapture of Izium by Ukrainian forces during the 2022 Kharkiv counteroffensive, investigators discovered several mass graves in a wooded area near the city. One site alone contained at least 440 bodies, marked mostly with simple wooden crosses and numbers rather than names. The Ukrainian government has stated it believes more than 1,000 civilian residents were killed during the battle for and subsequent occupation of Izium.
According to Ukrainian investigators, 447 bodies were exhumed from one of the sites, comprising 414 civilians (215 women, 194 men, and 5 children) and 22 servicemen, with the remaining bodies' gender undetermined as of 23 September 2022. Officials reported that most of the dead showed signs of violent death, and at least 30 bodies bore evidence of torture and summary execution, including ropes around necks, bound hands, broken limbs, and genital amputation. Some deaths were attributed to artillery shelling and lack of access to healthcare during the occupation rather than direct violence.
Identification and recovery efforts were aided by the head of the local funeral home, who said he had been instructed by occupying forces to mark graves only with numbers while privately recording names and corresponding numbers in a journal. Local firefighters assisted in exhuming remains, observing a moment of silence before examining bodies for identifying features and transporting them to a morgue for forensic examination.
Survivors interviewed said Russian forces had targeted specific individuals using pre-existing lists identifying military personnel, families of military members, and veterans of the Donbas conflict that began in 2014. Witnesses also described public strip searches used to terrorize residents during the selection of victims. One local resident, identified as Tamara Volodymyrivna, said she had been permitted to bury some territorial defense members and soldiers but was barred from burying the majority of Ukrainian military casualties and did not know where their bodies were located.
Kharkiv regional governor Oleh Synyehubov stated that 99 percent of exhumed bodies showed signs of violent death, including individuals found with hands tied behind their backs and one person buried with a rope around his neck, describing these as signs of torture and execution, and noting that children were also among the dead.
The United Nations announced plans to send monitors to Izium, and the investigation was supported by International Criminal Court experts. Ukrainian President Volodymyr Zelenskyy compared the discovery to the Bucha massacre; on 26 September 2022 he said two additional mass graves containing "hundreds of people" had been found. Russia denied the allegations, with pro-Russian social media accounts calling the findings a "Western fabrication" and Kremlin spokesman Dmitry Peskov describing both the Izium and Bucha findings as "lies." Western officials and foreign governments, including the United States, France, and Spain, condemned the reported atrocities and called for accountability and adherence to international humanitarian law.
