Ukrainian officials said they have asked the International Criminal Court (ICC) to visit the mass graves seen in Bucha, a suburb northwest of Kyiv, so experts can gather evidence of possible Russian war crimes.
The request comes as Kyiv's mayor, Vitali Klitschko, said the discovery of the graves - made as Ukrainian troops recaptured territory and Russian forces pulled back from towns they had seized in the war's earliest days - could "only be described as genocide."
