Truth Hounds

Truth Hounds is a Ukrainian human rights organization focused on documenting, investigating, and helping prosecute war crimes and other serious violations of international humanitarian and human rights law. Its work is centered on Ukraine and the wider Eastern European conflict environment, while its evidence and analytical products are also used in international accountability processes. The organization combines field investigation with open-source intelligence, witness interviewing, digital archiving, and cooperation with police, prosecutors, courts, and foreign investigative bodies. Its investigators collect eyewitness accounts and other source material, verify information through methods such as satellite-image analysis and review of publicly available media, and organize the resulting evidence for use in criminal proceedings. The organization has reported conducting more than 260 field missions, recording over 5,000 testimonies, identifying more than 200 suspects in international crimes, and completing 55 in-depth investigations. Truth Hounds has worked on cases and investigations connected with the Kramatorsk rocket strike, the destruction of Mariupol, and the killing of Ukrainian writer Volodymyr Vakulenko. Its research also examines the consequences of armed conflict for human rights, the environment, and economic security. Topics cited in its work include the destruction of the Kakhovka Dam and risks associated with the Zaporizhzhia Nuclear Power Plant. A central part of the organization’s evidence-management approach is IDoc, a database intended to systematize incident information and support the preparation of larger criminal cases. Truth Hounds also provides training and workshops for investigators, lawyers, and human rights defenders, including instruction related to international humanitarian law and investigative methods. Internationally, the organization cooperates with foreign investigators, prosecutors, archives, and accountability initiatives. It has submitted nine reports to the International Criminal Court, including material concerning the persecution of Crimean Tatars and attacks on civilians following Russia’s full-scale invasion of Ukraine on 24 February 2022. In 2023, Truth Hounds received the Andrei Sakharov Freedom Award. In 2025, Russia designated the organization as an “undesirable organization,” a state classification that restricts its activities in Russia and exposes associated activity to legal risk.

Truth Hounds is a Ukrainian human rights organization whose work is devoted to documenting alleged war crimes and supporting criminal accountability. Rather than operating as a conventional commercial brand, it functions as an investigative and advocacy organization whose principal outputs are evidence files, analytical reports, databases, training programs, and cooperation with justice institutions. Its investigative model combines direct field missions with digital and documentary research. Investigators gather eyewitness testimony, preserve relevant records, examine open-source material, and use tools such as satellite imagery and social-media archiving to establish what happened, where events occurred, and who may have been responsible. The organization also works with police and judicial authorities and with foreign investigators and prosecutors pursuing cases under universal-jurisdiction principles. Truth Hounds has reported a substantial body of work since its establishment, including more than 260 field missions, over 5,000 recorded testimonies, more than 200 identified suspects in international crimes, and 55 in-depth investigations. Its cited investigations include the Kramatorsk rocket strike, the destruction of Mariupol, and the killing of writer Volodymyr Vakulenko. The group has also examined the wider effects of armed conflict, including environmental and infrastructure damage associated with the Kakhovka Dam and the Zaporizhzhia Nuclear Power Plant. The organization’s IDoc database is intended to bring incident records and supporting material into a structured system that can be used for large-scale criminal investigations. This reflects Truth Hounds’ emphasis on converting dispersed testimony and public information into organized evidence suitable for lawyers, prosecutors, courts, and other accountability mechanisms. It supplements investigative work with workshops and training for investigators, legal professionals, and human rights defenders on international humanitarian law and investigative methodology. Truth Hounds has extended its work beyond domestic Ukrainian proceedings through international cooperation. It has submitted nine reports to the International Criminal Court, including reports concerning persecution of Crimean Tatars and attacks on civilians after Russia’s full-scale invasion of Ukraine began on 24 February 2022. Recognition came in 2023 when the organization received the Andrei Sakharov Freedom Award. In 2025, Russia designated Truth Hounds as an undesirable organization, a measure reflecting the political and legal pressure placed on organizations documenting alleged abuses connected with Russia’s war against Ukraine.
