The pope, speaking in a heavy and measured voice, made the comments in a phone call broadcast on the Italian Bishop's Conference TG2000 on Saturday.
Asked if there can be a religious justification for such attacks, Francis responded: "Religious and human. This is not human."
I am deeply saddened by the terrorist attacks in Paris. Please join me in prayer for the victims and their families. #PrayersForParis— Pope Francis (@Pontifex) November 14, 2015
Francis says he was "close to the much-beloved people of France, I am close to the relatives of the victims and I pray for all of them."
