Many Indigenous leaders from across the Prairies are calling for a search for more mass graves following news of 215 bodies discovered at the site of a former residential school in Kamloops, B.C.

In Saskatchewan, where the country's last residential school closed in 1996, the Federation of Sovereign Indigenous Nations called for ground radar searches at multiple sites where they say they've been informed of potential mass graves.

Manitoba NDP Leader Wab Kinew says in a statement that as the son of a residential school survivor and the father of a child the same age as the youngest victims found in B.C, the news hit home hard.

Kinew called for a commitment from every level of government to search the sites of all other residential schools, in order to know the truth.
