The remains of nine more Native American children who died at a notorious government-run boarding school in Pennsylvania over a century ago were disinterred from a small Army cemetery and returned to families, authorities said Wednesday.

The remains were buried on the grounds of the Carlisle Barracks, home of the U.S. Army War College. The children attended the former Carlisle Indian Industrial School, where thousands of Indigenous children were taken from their families and forced to assimilate to white society as a matter of U.S. policy.
