There were signs of torture when bodies were found at a mass burial site in a city that was recently reclaimed from the Russians.
Mass graves were found in the area of Izium after it was regained from Russian forces, according to the defense ministry.
The largest burial site in the region contained over 400 graves.
According to the Associated Press, the bodies unearthed from the area had "traces of a violent death, but also of torture."
The gruesome discovery was just the beginning, according to Enin.
We carefully documented all the war crimes that took place. According to the AP, Enin said in an interview that the best crimes can only be exposed over time.
Some of the first bodies that were exhumed had rope around their neck, according to the head of the prosecutor's office in Kharkiv.
Some of the bodies were bound behind their backs.
Most of the people found were civilians, according to Ukrainian officials.
Serhii Bolvinov said that some of the dead Ukrainians were killed from shelling.
Sky News quoted Bolvinov as saying that some died because of the airstrikes.
Ukrainian President Volodymyr Zelenskyy said that Russia leaves death everywhere after calling out the Ukrainian cities of Mariupol and Bucha.
Zelenskyy said that Russia must be held responsible for that.
In the last few days, Ukrainian forces have reclaimed thousands of square miles of territory from Russians in a stunning counteroffensive.
