COLOMBO, Sri Lanka — Pope Francis brought calls for reconciliation as well as justice in Sri Lanka today at the start of a weeklong Asian tour, saying the island nation can’t fully heal from a quarter-century of ethnic civil war without pursuing the truth about abuses that were committed.

In a show of ethnic coexistence, the pope’s welcoming ceremony featured traditional dancers and drummers from both majority Sinhalese and minority Tamil ethnic groups.

With 40 elephants dressed in colorful costumes lining the airport road behind him, Francis said that finding true peace after so much bloodshed “can only be done by overcoming evil with good, and by cultivating those virtues which foster reconciliation, solidarity and peace.”

He didn’t specifically mention Sri Lanka’s refusal to cooperate with a U.N. investigation into alleged war crimes committed in the final months of the war. But he said, “The process of healing also needs to include the pursuit of truth, not for the sake of opening old wounds, but rather as a necessary means of promoting justice, healing and unity.”

Tamil rebels fought a 25-year civil war to demand an independent Tamil nation after decades of perceived discrimination by governments dominated by the Sinhalese majority. U.N. estimates say 80,000 to 100,000 people were killed during the course of the war, which ended in 2009; other reports suggest the toll could be much higher.

Sri Lanka’s new president, Maithripala Sirisena, has promised to launch a domestic inquiry into wartime abuses, but has also pledged to protect everyone who contributed to the defeat of Tamil Tiger separatists from international legal action.

A 2011 U.N. report said up to 40,000 ethnic Tamil civilians may have been killed in the last months of the civil war, and accused both sides of serious human rights violations. It said the government was suspected of deliberately shelling civilians and hospitals and preventing food and medicine from getting to civilians trapped in the war zone. The rebels were accused of recruiting child soldiers and holding civilians as human shields and firing from among them.
