The confirmed civilian death toll has surpassed 7,000 people in Ukraine since Russia's military invasion nearly one year ago, with more than 11,000 injured, although the UN High Commissioner for Human Rights said on January 16 it believes the number is actually higher. "Most of the civilian casualties recorded were caused by the use of explosive weapons with wide-area effects, including shelling from heavy artillery, multiple-launch rocket systems, missiles, and air strikes," it said in a report. It added that actual figures were "considerably higher," as information from locations with intense hostilities is difficult to verify.
