Pope Leo XIV surprised a huge crowd of more than 100,000 young Catholics when he unexpectedly showed up at a 2025 Jubilee welcoming ceremony.

The Pope emerged in St. Peter’s Square riding his popemobile at the end of an evening Mass that kicked off the Jubilee of Youth, a weeklong celebration for young Catholics, and which marks the first big youth event of his pontificate, reports the Associated Press (AP).

An estimated 120,000 young pilgrims who were packed into the square, upon sighting the Pope, "erupted in shocked cheers and chants", as the pontiff looped around the square and went up and down the boulevard leading to it on Tuesday, 29 July.
