International Criminal Court (ICC) chief prosecutor Karim Khan Wednesday told reporters during his visit to Bucha that “Ukraine is a crime scene” as the court continues its investigation into alleged war crimes in the country.

The ICC opened its investigation into alleged war crimes committed in Ukraine on March 2 this year, one week after Russia began its invasion of the country. At that point, 39 ICC state parties had referred the situation in Ukraine to the ICC. This included the UK, Canada, France, and Australia. The investigation will also investigate crimes committed in Ukraine since November 21, 2013.

Khan, speaking on his visit to Bucha, said: “Ukraine is a crime scene. We’re here because we have reasonable grounds to believe that crimes within the jurisdiction of the ICC are being committed. We have to pierce the fog of war to get to the truth.”

Despite not being a member of the ICC, the US is reportedly deciding whether or how to assist in the ICC’s investigation. The Biden administration has continuously been very vocal about its desire to hold Putin accountable for Russia’s alleged war crimes in Ukraine.
