Earlier in the week, the Pope decried a "barbarous" missile strike on a Ukrainian mall that left 18 dead, saying that he carries "dear and martyred Ukraine" in his heart every day. 

The Pope's comments this week mark a more forceful condemnation of Russia's actions since Putin invaded Ukraine on Feb. 24.
