I did however find: Alleged crimes committed in the context of situation in Ukraine since 21 November 2013
On 28 February 2022, the ICC Prosecutor announced he would seek authorisation to open an investigation into the Situation in Ukraine, on the basis of the Office's earlier conclusions arising from its preliminary examination, and encompassing any new alleged crimes falling within the jurisdiction of the Court.
On 2 March 2022, the Prosecutor announced he had proceeded to open an investigation into the Situation in Ukraine on the basis of the referrals received. In accordance with the overall jurisdictional parameters conferred through these referrals, and without prejudice to the focus of the investigation, the scope of the situation encompasses any past and present allegations of war crimes, crimes against humanity or genocide committed on any part of the territory of Ukraine by any person from 21 November 2013 onwards.
