This article examines international crimes committed on the territory of Ukraine since February 24, 2022. Ukraine faces explicit acts of aggression, with a multitude of war crimes—including murder, sexual violence, and deliberate attacks on civilian property and infrastructure—being perpetrated within its borders. Additionally, there are indications of genocidal intent. Urgent attention is required to investigate the violations of international humanitarian law. Further, the article identifies the main causes of war crimes committed by the military: military errors or failures, the use of civilians as “human shields,” insufficient discipline, inadequate inculcation of legal norms related to international humanitarian law and Just War Theory within military ranks, and the use of targeted terror aimed at crushing the enemy’s will to resist. The author examines the interrelation of war crimes and information warfare in light of the importance of discerning truth amidst a sea of disinformation and cover-up. Finally, he explores national and international mechanisms for bringing perpetrators of crimes to justice, as well as seeking compensation for the damage they caused.
