An estimated one million Roman Catholics gathered at Ndolo Airport in the Democratic Republic of the Congo’s capital of Kinshasa on February 1, as Pope Francis celebrated Mass after arriving in the country the day before, according to Vatican News.

Footage by Gianluca Teseo shows crowds singing, dancing, and waving flags in Kinshasa.

Addressing conflict in the country, Francis said, “For all of you in this country who call yourselves Christians but engage in violence, the Lord is telling you: ‘Lay down your arms, embrace mercy.’”
