Canadian Prime Minister Justin Trudeau doubled down on his explosive charge that “Indian government agents” were behind Khalistani terrorist Hardeep Singh Nijjar’s killing, claiming such “credible allegations” were shared with India weeks ago. Trudeau had first linked Nijjar’s killing to India on Monday, prompting a quick and stern denial by India. Canada has shared no specific information regarding its charges, India said, flagging “politically condoned hate crimes and criminal violence” in that country.The allegation triggered tit-for-tat moves like expelling diplomats that escalated underlying tensions to a major diplomatic crisis between the two countries. India has suspended visa services citing “security threats” to its High Commissions and consulates in Canada.Both India and Canada issued travel advisories and expelled a senior diplomat of the other country, wrapping a week of tensions, multiple rounds of charges and counterattacks. India has asked its citizens living in or travelling to Canada to exercise caution in view of “growing anti-India activities”.
