Canadian Prime Minister Justin Trudeau says his government is investigating "credible allegations" that Indian agents may have been involved in the slaying of an exiled Sikh leader in June near Vancouver.
Trudeau told a parliamentary committee on Monday that the government is "actively pursuing" evidence of a link between India and the killing of Hardeep Singh Nijjar, a Canadian citizen.
"The involvement of any foreign government in the murder of a Canadian citizen on Canadian soil is an unacceptable violation of our sovereignty," Trudeau said.
He called "in the strongest possible terms" on the Indian government to cooperate in clearing up the matter.
Nijjar, whom India had declared a wanted terrorist, was gunned down on June 18 in Surrey, a suburb of Vancouver that is home to one of the largest Sikh populations in Canada.
Nijjar advocated for the creation of an independent Sikh state to be carved out of parts of northern India. India accused Nijjar of carrying out terrorist attacks in India, a charge he denied.
Tensions between India and Canada have been simmering over the unsolved slaying, and Indian unhappiness over how Ottawa has handled right-wing Sikh separatists.
