Pope Leo XIV tells a massive crowd of Catholic youths they are a sign that a different world is possible: 'We are with the young people of Gaza. We are with the young people of Ukraine.'

The Chicago-born pope said that a gathering of young faithfuls in Rome was a "sign that a different world is possible."

Leo displayed his fluency in speaking to the kids in Spanish, Italian and English about the dangers of social media, the value of true friendship and the need to have courage to make radical choices like marriage or religious vows.
