Pope Francis is greeted by Turkish President Recep Tayyip Erdogan (L), Turkish Prime Minister Ahmet Davutoglu (3rd-R) and other officials upon his arrival for a meeting at the presidential palace in Ankara on November 28, 2014. Pope Francis arrived in Turkey for his first visit to the overwhelmingly Muslim but officially secular state, in a challenging trip aimed at building bridges with Islam and supporting the embattled Christian minorities of the Middle East.
