Pope Leo XIV, the first American leader of the Catholic Church, previously known as Robert Francis Prevost, gave his first Sunday blessing as pope and called for peace in the Ukraine-Russia conflict and a ceasefire in Gaza.

The newly elected pope followed in his predecessor's footsteps, calling for ceasefires in Ukraine, Gaza, India, Pakistan and Kashmir.

I, too, address the world’s great powers by repeating the ever-present call ‘never again war,’” Leo said from St. Peter’s Basilica.
