* The International Criminal Court has a "historic" role to play in bringing justice for crimes committed in the war in Ukraine and ensuring long-term security, President Volodymyr Zelenskiy said on Tuesday after meeting with the ICC's top prosecutor. * The Kremlin said it did not believe a statement by Ukrainian presidential adviser Mykhailo Podolyak that Ukraine does not launch attacks against targets on Russian territory.
