Canadian Prime Minister Justin Trudeau -- amid escalating tension with India -- has said he is not looking to "provoke" India or "escalate" tension, but wants New Delhi to take the killing of a Sikh separatist with "utmost seriousness". Justin Trudeau had earlier alleged the involvement of "agents of the Indian government" in the killing of Sikh separatist Hardeep Singh Nijjar, which took place in June. It had raised eyebrows and the US had said it was "deeply concerned" about the allegations.
