February 24, 2026 marks four years since Russia’s full-scale invasion of Ukraine. ICJI joins our partners in the Atrocity Crimes Advisory Group for Ukraine (ACA) in strongly condemning the flagrant and on-going violations of international law committed by Russian personnel, and reaffirming our unwavering commitment to supporting Ukrainian authorities in their investigations and prosecutions of atrocity crimes that meet the highest international standards.

“The laws of war exist for a reason: because even in armed conflict, there is conduct that violates the human conscience and is therefore prohibited,” said Amb. (Ret.) Clint Williamson, Lead Coordinator of ACA and Senior Director for International Justice at Georgetown University Law Center. “What we have witnessed during these last four years is blatant disregard for international law by Russian personnel. This is first and foremost a tragedy for the people of Ukraine. But it is not their burden to bear alone. There is an important role for international justice actors to play, and ACA is committed to leveraging its deep expertise to assist Ukrainian prosecutors in ensuring that perpetrators of these terrible crimes are held accountable for their actions.”

Over the past four years, Ukraine has recorded nearly 217,000 reports of atrocity and aggression-related crimes, including torture; sexual violence; forced deportations of children to Russia; mass killings; targeting of civilians and civilian infrastructure, such as residential buildings, hospitals and schools; and destruction of cultural heritage.
