Euronews reported the information.According to the latest investigation, Ukrainian children forcibly deported by Russian troops have been taken to at least 210 institutions in Russia and the temporarily occupied territory of Ukraine since February 2022. The HRL team at the Yale School of Public Health, which led the investigation, said the actual number is likely higher.According to the latest findings, Russia is “operating a potentially unprecedented system of large-scale reeducation, military training, and dormitory facilities capable of holding tens of thousands of children from Ukraine for long periods of time.”The HRL investigation uncovered logistical and operational capabilities aimed at "russification" of children taken from their home communities in Ukraine. In this study, HRL identifies eight types of facilities, ranging from summer camps and sanatoriums to a military base and, in one case, a monastery.Children were held in these locations for varying lengths of time: some have gone temporarily and returned home, while other groups of children were held indefinitely.Among the Ukrainian children placed in this Russian network of facilities are those who were taken from Ukrainian state institutions and other care facilities for children without guardians and/or children with physical disabilities.The HRL team says its investigation also found children who had been forcibly separated from their parents in frontline areas since 2022, and children who had been taken directly from their parents by Russian-affiliated officials in filtration camps set up in and around Mariupol in early spring 2022.The 210 locations documented by HRL in its research are part of a network facilitating the transfer of Ukrainian children, covering the temporarily occupied territories of Ukraine and Russia's Black Sea regions to the Pacific coast.According to the investigation, the places of deportation include universities in city centers and remote camps in Siberia. Russia has been deporting, “re-educating,” militarizing, and forcibly detaining children from Ukraine since at least 2014 in the temporarily occupied territories of Crimea, Luhansk, and Donetsk regions.HRL has confirmed that the Russian government directly controls more than half of the locations identified in this report.On May 1, Ukraine launched the Register of Deported or Forcibly Displaced Children, a tool that collects, summarizes, and processes information about Ukrainian children illegally taken to Russia.
