For a committed coalition of Ukrainian and international organizations dedicated to collecting and preserving evidence of human rights violations, the documentation of Russian war crimes began in that first wave of invasion and occupation in 2014. Ukrainian human rights groups and the UN Human Rights Monitoring Mission have been documenting serious human rights abuses since Russia’s original invasion. Dmytro Koval, a human rights legal expert and Associate Professor at the National University of Kyiv-Mohyla Academy who works with Truth Hounds, says new limitations on investigations in the active war zone mean investigators are focusing more on collecting open source information to provide leads to pursue interviews with witnesses.
