Pope Francis, speaking after warning Russian President Vladimir Putin about the possible use of nuclear weapons, said that even thinking about such an act would be "madness." This was reported by the CNN agency.

 The pope discussed his trip to Kazakhstan with people during an audience in St. Peter's Square and praised the Central Asian country for giving up nuclear weapons after gaining independence in 1991.

 "It was courageous. While in this tragic war some people think nuclear weapons are just madness, this country first said no to nuclear weapons," Pope Francis said, without naming either Russia or Putin.

 Francis also told those present about the conversation he had on Tuesday with Cardinal Konrad Krajewski, the head of his charitable organization that delivers aid to Ukraine.

 Vatican media reported that Krajewski came under fire while delivering humanitarian aid to Zaporizhzhya. Krajewski also visited mass burials in Izyum.

 "He (Kraevsky) told me about the pain of these people, the savage actions, the horror, the tortured bodies they find. Let's unite with these people, so noble and tortured," he said.
