Hundreds of thousands of mourners and world leaders, including US President Donald Trump, gathered in St. Peter's Square for the funeral of Pope Francis, the Catholic Church's first Latin American leader. The funeral was marked by an outpouring of support for the Argentine pontiff, who was known for his compassion and efforts to make the Church more inclusive. More than 50 heads of state were in attendance, including Trump, who met with world leaders before the ceremony. The funeral was followed by a slow drive through the streets of Rome, and marks the beginning of nine days of official Vatican mourning for Francis.
