Pope Francis said in an interview published on Tuesday that he asked for a meeting in Moscow with Russian President Vladimir Putin to try to stop the war in Ukraine but had not received a reply.
The pope also told Italy's Corriere Della Sera newspaper that Patriarch Kirill of the Russian Orthodox Church, who has given the war his full-throated backing, "cannot become Putin's altar boy".
Francis, who made an unprecedented visit to the Russian embassy when the war started, told the newspaper that about three weeks into the conflict, he asked the Vatican's top diplomat to send a message to Putin.
He said the message was "that I was willing to go to Moscow. Certainly, it was necessary for the Kremlin leader to allow an opening. We have not yet received a response and we are still insisting".
He added: "I fear that Putin cannot, and does not, want to have this meeting at this time. But how can you not stop so much brutality?"
Before the interview, Francis, 85, had not specifically mentioned Russia or Putin publicly since the start of the conflict on Feb. 24.
