Who was Hardeep Singh Nijjar, the Sikh activist whose killing has divided Canada and India?

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. Nijjar was a prominent member of a movement to create an independent Sikh homeland known as Khalistan, and at the time of his death was organizing an unofficial referendum among the Sikh diaspora with the organization Sikhs For Justice.
