The paper says it has obtained three videos that show how Russian paratroopers rounded up and killed at least eight Ukrainian men in Bucha on March 4, in what appears to be a war crime.
The videos, filmed by a security camera and a witness in a nearby house, provide clear evidence that the men were in the custody of Russian troops minutes before being executed, The New York Times reported.
The United Nations Human Rights Council this month voted to set up an investigation into possible war crimes by Russian troops in Ukraine.
Members on May 12 passed a resolution by an overwhelming majority to order an inquiry into events in Ukraine's Kyiv region and other areas that were temporarily held by Russian troops earlier this year.
The UN High Commissioner for Human Rights, Michelle Bachelet, was quoted as saying at the time that there were many examples of possible Russian war crimes in Ukraine.
"The scale of unlawful killings, including indicia of summary executions in areas to the north of Kyiv, is shocking," Bachelet said, as quoted by the Reuters news agency.
Meanwhile, Ukrainian Deputy Foreign Minister Emine Dzhaparova told the UN Human Rights Council that areas that were under Russian occupation in late February and March "experienced the most gruesome human rights violations on the European continent in decades," according to Reuters.
A Polish deputy justice minister told an international conference in Lithuania earlier this month that Poland had collected more than 1,000 witness statements on Russian atrocities in Ukraine.
