Pope Francis (L) greets Supreme Patriarch and Catholicos of All Armenians, Karekin II during an Armenian-Rite mass marking 100 years since the mass killings of Armenians under the Ottoman Empire, on April 12, 2015 at St Peter's basilica in Vatican. Pope Francis uttered the word "genocide" on Sunday to describe the mass murder of Armenians 100 years ago, sparking fury from Turkey which slammed the term as "far from historical reality".
