Pope Leo XIV, the first American to head the global Catholic Church, pledged on Wednesday to make "every effort" for peace and offered the Vatican as a mediator in global conflicts, saying war was "never inevitable".

Pope Leo XIV has taken over the Vatican’s official social media handles, with a first Instagram post on Tuesday repeating the first words he said to the world as pope: “Peace be with you all!” The @Pontifex – Pope Leo XIV post featured some of the photos that have documented the first days of history’s first American pope.

Pope Leo XIV, the first U.S. pope in history, addressed the crowd at the Vatican Thursday shortly after white smoke billowed from the roof.
