At least 2.5 million people attended a giant mass held by Pope Leo XIV in Buenos Aires, Argentina, marking the biggest event of his 12-day trip to South America and one of the most important moments of his papacy.
According to the Vatican, thousands of believers gathered along the streets of the Argentine capital, some of them even spending the night outdoors to secure a seat as close as possible to the Pope.
Large crowds waved Vatican flags and chanted his name as he rode in the open papal vehicle.

During the sermon, Pope Leo XIV expressed joy at the magnificent reception and devotion of the faithful, emphasizing the importance of religion in a region where the influence of the Catholic Church has faced new challenges in recent years.
His visit to Argentina is the first by a Pope since 1987. During his stay, Leo XIV also met with President Javier Milei, whom he asked to show care for the poorest sections of society, at a time when the country is facing economic difficulties and cuts in social spending.
The Pope also raised concern about the difficulties of Argentine families, citing job insecurity, domestic violence, separations and addictions affecting young people.
Before the mass, he also visited a care center for people with disabilities on the outskirts of Buenos Aires, where he emphasized that the progress of a nation is not measured only by economic success, but also by how it treats and includes the most needy people.
Pope Leo XIV is on a tour of Uruguay, Argentina and Peru, which ends on November 17. This visit is considered a special return to Latin America, where he has served for many years as a missionary in Peru.
