After Partial Russian Retreat, Chilling Signs of Horrors Against Ukrainians RevealedAlmost 2,000 innocent people have been killed by Russian forces in Bucha, Irpin, Mariupol, Ukraine – some just for speaking Ukrainian or having Ukrainian symbols. VOA’s Eastern Europe Bureau Chief Myroslava Gongadze was granted exclusive access to the scene of a mass graveyard in Izium in the Kharkiv region that contains more than 400 bodies. Most of them apparently died particularly violent deaths, with many victims found with their hands tied behind their backs, ropes around their necks, broken bones, and gunshot wounds. United Nations experts and Ukrainian officials have pointed to new evidence of war crimes in Ukraine.   The head of a U.N.-mandated investigation body said Friday war crimes including rape, torture and the confinement of children have been committed in Russian-occupied areas of Ukraine. "Based on the evidence gathered by the commission, it has concluded that war crimes have been committed in Ukraine," Erik Mose, who heads the Commission of Inquiry on Ukraine, told the U.N. Human Rights Council in Geneva. He did not specify who was to blame, but the commission has focused on areas previously occupied by Russian forces, such as Kyiv, Chernihiv, Kharkiv and Sumy. Investigators from the commission, created by the rights council in March, visited 27 places and interviewed more than 150 victims and witnesses A U.S. envoy told the council, "Numerous sources indicate that Russian authorities have interrogated, detained and forcible deported between 900,000 and 1.6 million Ukrainian citizens." U.S. Ambassador Michele Taylor, U.S. permanent representative to the council, added, "We urge the commissioners to continue to examine the growing evidence of Russia's filtration operations, forced deportations and disappearances.” Russia denies deliberately attacking civilians. Russia was called on to respond to the allegations at the U.N. Human Rights Council meeting, but its seat was left empty. There was no immediate official reaction from Moscow. Mobilization fallout In the meantime, more than 730 people were detained across Russia at protests Saturday against a mobilization order of 300,000 military reservists, a rights group said, three days after President Vladimir Putin ordered Russia's first military call-up since World War II for the conflict in Ukraine. The independent OVD-Info protest monitoring group said it was aware of detentions in 32 different cities, from St. Petersburg to Siberia. Unsanctioned rallies are illegal under Russian law, which also forbids any activity considered to defame the armed forces. Footage from the same protest showed Russian officers carrying men and leading women to police vans. Russia's first public mobilization since World War II—to shore up its faltering invasion of Ukraine—also has triggered a rush for the border by eligible men. Russian referendums Western nations and Ukraine have labeled a “sham” the voting on referendums in Russian-held regions of Ukraine asking residents if they want their regions to be part of Russia. Voting began Friday on Russian referendums aimed at annexing four occupied regions of Ukraine. Some local officials said voters were being intimidated and threatened. In the balloting, scheduled to run from Friday to Tuesday in the provinces of Luhansk, Kherson and the partly Russian-controlled Zaporizhzhia and Donetsk regions, voters are being asked if they want their areas to become part of Russia. Polls also opened in Russia, where refugees and other residents from those areas could vote. The West and Ukraine said the voting is illegal under international law. “Any elections or referenda on the territory of Ukraine can only be announced and conducted by legitimate authorities in compliance with national legislation and international standards,” the Organization for Security and Cooperation in Europe said in a statement. “Therefore, the planned ‘referenda’ will be illegal." Ukrainian officials said people were banned from leaving some occupied areas until the vote was over, armed groups were going to homes to force people to cast ballots, and employees were told they could be fired if they did not participate. Serhiy Haidai, Ukraine's Luhansk governor, said in the town of Starobilsk, the population was banned from leaving and people were being forced out of their homes to vote. "Today, the best thing for the people of Kherson would be not to open their doors," said Yuriy Sobolevsky, the displaced first deputy council chairman of Kherson region. The results of the referendums, expected soon after the voting, are almost certain to support joining Russia. "We are returning home," said the Russian-backed leader of Donetsk, Denis Pushilin. "Donbas is Russia." "All of us have been waiting for a referendum on joining Russia for eight long years," said Leonid Pasechnik, the Russian-backed leader of Luhansk. "We have already become part of Russia. There remains only a small matter – to win [the war]." Ukraine says it will never accept Russian control of any of its territory. The referendums were quickly organized after Ukraine earlier this month recaptured large swaths of the northeast in a counteroffensive. By incorporating the four areas, Moscow could portray attacks to retake them as an attack on Russia itself - potentially even using that to justify a nuclear response. In a televised address this week, Putin said the West is trying to weaken and destroy Russia and that his country will “use all the means at our disposal to protect Russia and our people.” Some information for this report came from The Associated Press and Reuters.
