The White House said reports of a mass burial site in the eastern Ukrainian city of Izium are "horrifying" and "repugnant."
John Kirby, the strategic communications adviser at the National Security Council, said the discovery of what Ukrainian officials say is at least 440 graves at the site was "in keeping with the kind of depravity and the brutality with which Russian forces have been prosecuting this war against Ukraine and the Ukrainian people."
Kirby said the United States would continue to “actively support efforts to document war crimes and atrocities that Russian forces commit in Ukraine and assist national and international efforts to identify and hold Russians accountable.”
Ukraine’s Center for Strategic Communications said on Thursday that some of the graves discovered at Izium were “fresh” and that the bodies buried there were “mostly civilians.”
Izium was subject to intense Russian artillery attacks in April, and the city, which sits near the border between the Kharkiv and Donetsk regions, became an important hub for the invading military during five months of occupation.
