Pope leads secret mission to rescue Ukrainian children from Russia.

Pope Francis has announced a secret peace "mission" to bring home Ukrainian children who were taken to Russia during the war. The Vatican has already helped mediate some prisoner exchanges and is willing to do "all that is humanly possible" to reunite families. The International Criminal Court has 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. Russia has denied any wrongdoing, contending the children were moved for their safety. Ukrainian officials have said at least 20,000 children have been taken to Russia, but the actual figure could be much higher.
