In a statement, Minister Jassem al-Jaff said his ministry has no database of the number of missing refugees, citing the huge number of refugees and camps, which makes it difficult to track missing persons.
He said Iraq could use the help of the International Commission on Missing Persons to assist displaced families who had lost members over the past period.
He made the statement meeting with Lena Larsson, head of the commission’s program in Iraq, who, according to the ministry’s statement, expressed readiness for help.
Iraq authorities declared victory over IS in December 2017, and say more than half of refugees have been repatriated.
Security and relie teams have frequently declared the discovery of numerous mass graves containing the remains of civilians and security personnel executed by Islamic State militants over the past three years.
