Crimes committed at the notorious Izoliatsiia detention facility in occupied Donetsk may constitute crimes against humanity, according to a report released by Ukrainian human rights organization Truth Hounds on Monday. The report says the facility became the site of a systematic campaign of unlawful imprisonment, torture, sexual violence and enforced disappearances after armed fighters from the self-proclaimed “Donetsk People’s Republic” (DPR) took control of the complex on June 9, 2014.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. The report is based on 30 survivor testimonies, interviews with institutions, previous human rights investigations, documentary evidence and open-source research. “The available evidence supports the conclusion that these crimes formed part of a widespread or systematic attack against a civilian population and may amount to crimes against humanity,” the report says. From cultural landmark to site of abuse Before Russia’s occupation of parts of eastern Ukraine, Izoliatsiia was one of Donetsk’s best-known contemporary art centers. Truth Hounds said the seizure of the site transformed it from a cultural institution into a detention facility used by occupation authorities to intimidate, punish and repress civilians. Researchers traced the prison’s development from early armed formations in occupied Donetsk to the so-called “Ministry of State Security” under the DPR, identifying links to Russia’s Federal Security Service (FSB) and other Russian officials.
