The Prosecutor of the International Criminal Court in The Hague, Karim Khan, said that after the appeal of 39 member states, the court is launching a full-scale investigation into crimes related to Russia's military aggression against Ukraine.

In a statement released by the ICC, Khan notes that he has already "notified the ICC Presidency a few moments ago of my decision to immediately proceed with active investigations in the Situation."

"In its preliminary examination of the Situation in Ukraine, my Office had already found a reasonable basis to believe crimes within the jurisdiction of the Court had been committed, and had identified potential cases that would be admissible... Our work in the collection of evidence has now commenced," Khan said.

Earlier, British Prime Minister Boris Johnson announced that 38 countries have filed the largest appeal to the ICC due to Russia's invasion of Ukraine.

Press Secretary of the President of the Russian Federation Dmitry Peskov said earlier that Moscow rejected allegations of war crimes in Ukraine, and the Russian Federation was not a member of the ICC.
