Pope Leo called for an end to the war in Yemen On Sunday, Pope Leo XIV, in his first public speech from the window overlooking St. Peter's Square in the Vatican after his latest surgery, called on the international community to act to stop the violence in Yemen. The leader of the world's Catholics expressed his concern especially about the humanitarian situation in the city of Taiz in southwestern Yemen. From the bottom of my heart, I want to stop the hostilities so that the people of Yemen and all the nations of the region can live in peace.
