Pope Francis issues toughest condemnation yet of Russia's war.

Without using the word "Russia" in his comments, the leader of the Roman Catholic Church said that the "unacceptable armed aggression" and "massacre" must stop. "Faced with the barbarity of killing of children, of innocents and unarmed civilians, no strategic reasons can hold up," he told 25,000 people in Vatican's St. Peter's Square during his Sunday blessing.
