NEW DELHI—Hardeep Singh Nijjar, a Sikh independence advocate whose killing two months ago is at the center of a widening breach between India and Canada, was called a human rights activist by Sikh organizations and a terrorist by India’s government.
Canadian Prime Minister Justin Trudeau said Monday that his government was investigating “credible allegations that agents of the Indian state were linked to the killing of a Canadian citizen” after Nijjar was gunned down on June 18 outside a Sikh cultural center in Surrey, British Columbia.
