Pope Francis leads secret peace mission in Ukraine.

Pope Francis revealed that a secret peace "mission" in Russia's war in Ukraine was underway, and the Vatican is willing to help facilitate the return of Ukrainian children taken to Russia during the war. The Holy See had already helped mediate some prisoner exchanges and would do "all that is humanly possible" to reunite families. The International Criminal Court issued an arrest warrant for Russian President Vladimir Putin and Russia's children's commissioner, accusing them of war crimes for abducting children from Ukraine.
