Indigenous groups in Canada are calling for a nationwide search for mass graves at residential school sites after the discovery of the remains of more than 200 children at one former school last week shocked the country. The Guardian quotes the chief of the Assembly of First Nations as saying that while it is not new to find graves at former residential schools, it’s always crushing to have that chapter’s wounds exposed. The Federation of Sovereign Indigenous Nations, which has compiled a list of initial sites where it hopes to complete radar ground searches, says finding the children’s remains and giving them proper burials was important to help First Nations communities and families find closure.
