After chatting and shaking hands with dozens of participants, Francis sat down to dine with them in the Franciscan convent. The guests included 12 refugees who fled war and conflicts in Nigeria, Eritrea, Mali and Syria, which was represented by three Christians who fled the besieged city of Aleppo.
Francis took his papal name from the peace-loving saint who was born in the Umbrian hill town, where Franciscans from the religious order founded by the medieval saint care for the basilica and its renowned artworks.
This year, Christians were invited to pray in the Basilica of St. Francis, while those from other religions will pray in the town that for centuries has drawn admirers of the saint who abandoned family wealth for an austere existence of preaching tolerance.
The closing event gathers all participants in Assisi's main square for speeches by the pope, Orthodox Patriarch Bartholomew I, a representative each from Islam, Judaism and Buddhism, and remarks from a victim of war. Then time was allotted for a moment of silence for victims of war.

From the start of his papacy in 2013, Francis has decried war and conflicts which he says are tantamount to a "Third World War in segments."
He has also pressed for countries and individuals to welcome refugees. As an example, he flew Syrian civil war refugees back to Rome with him after his visit to the Greek island of Lesbos, where thousands of those fleeing fighting and poverty had set foot in Europe after risky journeys in smugglers' boats.
Among those dining with Francis in Assisi was a 23-year-old man from Mali, who survived a voyage on a fishing boat from Libya, where human smugglers are based, to Sicily.
