Pope Leo XIV on Sunday used his Angelus address in St Peter’s Square to issue an appeal for peace and moral responsibility as world leaders grapple with the escalation in the Middle East following coordinated airstrikes by the United States and Israel against Iran.

The Holy Father’s words came as global attention focused on the intensifying conflict that began on Saturday with a major joint offensive dubbed “Operation Lion’s Roar”, when US and Israeli forces launched a series of air and missile strikes targeting strategic sites across Iran, including facilities in Tehran and other cities. The operation has triggered fierce retaliation from Tehran, widening hostilities across the region.
