Toronto, June 3 (TIWN) As Canadians fear discovery of more graves of indigenous children after the remains of 215 kids were found from the grounds of a former native school, the UN has called for an "exhaustive investigation" into the tragedy.

The discovery of the remains at the former Indian residential school in Kamloops in British Columbia led to calls on Tuesday for officially designating it as "genocide". 
 
Indian-origin Opposition leader Jagmeet Singh of the New Democratic Party said these schools were started with the aim of a "genocide" of indigenous people.
 
"These residential schools were not schools; they were institutions designed to eradicate and eliminate Indigenous people. They were institutions that were designed to perpetuate a genocide," he said.
 
Angry indigenous leaders wanted the Pope to apologise as Catholic missionaries ran these schools with government support.
 
Canada's first Prime Minister Sir John Macdonald too came under attack as he started these schools in 1883 and ordered Indigenous kids forcibly removed from their "savage" parents and placed in these schools.
