German President Joachim Gauck (2nd R) greets Metropolitian Augoustinos of the Greek Metropolitanate of Central Europe (L) German Cardinal Reinhard Marx (L) Bishop Heinrich Bedford-Strohm (3rd L) and Diradur Sradaryan, priest of the Armenian Apostolic Church (R) after making a speech during an Ecumenical service marking the 100th anniversary of the mass killings of 1.5 million Armenians by Ottoman Turkish forces, at the cathedral in Berlin April 23, 2015. Gauck on Thursday condemned the massacre of 1.5 million Armenians by Ottoman Turkish forces a century ago as "genocide", a term that the Berlin government had long rejected. He used the word in a speech to mark the 100th anniversary of what most Western scholars and two dozen governments regard as a genocide against an Armenian population that flourished in what is now modern Turkey. Turkey vehemently denies the charge. REUTERS/Fabrizio Bensch
