India, May 8 -- Canada's foreign minister has reiterated the allegation that Indian agents were connected to the killing of pro-Khalistan figure Hardeep Singh Nijjar on June 18 last year, even as India's envoy to the country has described as a "red line" the threat to its territorial integrity posed by Canadian citizens.

Speaking to the media in Ottawa, Canada's Minister of Foreign Affairs Melanie Joly, said, "Canada's position has always been clear. Our job is to protect Canadians and we stand by the allegations that a Canadian was killed on Canadian soil by Indian agents."

That statement came in the context of a question relating to the arrest of three Indian nationals by law enforcement for their alleged involvement in the murder.
