GENEVA (Reuters) -The U.N. Human Rights Council will decide on Thursday whether to launch an investigation into possible war crimes by Russian troops in the Kyiv area, a move that Russia said would amount to political score-settling.

       Members were due to vote on a resolution brought by Ukraine and supported by 59 other countries, to order a Commission of Inquiry to investigate events in the regions around Kyiv that were temporarily held by Russian troops.

       "The areas ... which have been under Russian occupation in late February and March have experienced the most gruesome human rights violations on the European continent in decades," Ukraine's First Deputy Minister of Foreign Affairs, Emine Dzhaparova, told the Council.

       As she spoke by video link, she held up a drawing that she said was made by an 11-year-old boy who was raped in front of his mother. "He actually lost the ability to speak after and the only way he communicates is with black lines," she said.

       Reuters was unable to verify Dzhaparova's account of what happened to the boy. A spokesperson for Russia's diplomatic mission did not immediately respond to a request for comment on her account.

       Russia, which has denied carrying out abuses in what it calls its "special military operation" in Ukraine, left its seat at the Geneva-based Council empty in protest.

       "Instead of discussing the true causes that led to the crisis in this country and looking for ways to resolve them, the 'collective West' is organising another political rout to demonize Russia," Moscow's ambassador to the U.N. in Geneva, Gennady Gatilov, said in an emailed statement.

       Chinese ambassador Chen Xu also complained of the "politicization" of the Council, saying the resolution could "add fuel to fire" of tensions surrounding Ukraine.

       Russia says it went into Ukraine on Feb. 24 to disarm the country and rid it of what the Kremlin calls anti-Russian nationalism fomented by the West. Ukraine and the West say Russia launched an unprovoked war of aggression.

       Russia was suspended from the 47-member Council last month over allegations of violations in Ukraine, although Moscow says it quit.

       At the same session on Thursday, the U.N. High Commissioner for Human Rights, Michelle Bachelet, said there were many examples of possible war crimes since the Russian invasion, saying that 1,000 bodies had been recovered so far in the Kyiv region.

       "The scale of unlawful killings, including indicia of summary executions in areas to the north of Kyiv, is shocking," she said.

       The Kremlin has said images of dead bodies on the streets of towns such as Bucha were staged to discredit its forces.

       Dozens of countries spoke in favour of Ukraine's resolution, which would also request Bachelet to provide an update at the council's June session on violations in the Russian-besieged port city of Mariupol.
