Canada has recalled 41 of its diplomats from India after the Indian government threatened to revoke their diplomatic immunity. The move comes as a result of a dispute over the killing of a Sikh separatist in Canada, with Canada alleging that India may have been involved. India has denied the allegation and accused Canada of harbouring separatists. The decision to remove diplomatic immunity is seen as a violation of international law and Geneva Convention on diplomatic relations. India’s action will impact the level of services to citizens of both countries. Tensions between Canada and India have escalated in recent months, with cancelled trade missions and frosty encounters between the leaders of the two countries. The United States is also concerned about the fallout from the allegations, which could impact its relationship with India. The killing of the Sikh separatist is believed to be linked to the Khalistan movement, which seeks an independent Sikh homeland. Canada is home to a large Sikh diaspora, many of whom have ties to Punjab, the Indian state where the movement originated.
