Leo welcomed by Recep Tayyip Erdoğan as he begins six-day itinerary that will also include visit to Lebanon

A new world war is being fought “piecemeal” and is endangering the future of humanity, Pope Leo has warned, as he arrived in Turkey for his first foreign trip since becoming head of the Catholic church.

Speaking in Ankara, where he was welcomed on Thursday by the Turkish president, Recep Tayyip Erdoğan, Leo said the world was experiencing “a heightened level of conflict on the global level, fuelled by prevailing strategies of economic and military power”.
