A United Nations report has accused Russia of summarily executing 77 civilians who were being held in arbitrary detention during its war in Ukraine. The report also documented more than 900 cases of arbitrary detention of civilians, including children and elderly people, with the vast majority of these cases perpetrated by Russia. The report’s findings were based on 1,136 interviews with victims, witnesses and others, plus 274 site visits and 70 visits to official places of detention run by Ukrainian authorities. The report comes after Russian President Vladimir Putin paid tribute to pilots who he said were killed fighting an aborted mutiny, while thanking Russians for showing patriotic solidarity in the face of the Wagner militia group's march on Moscow.
