NEW DELHI (Reuters) -India on Wednesday urged its nationals in Canada, especially students, to exercise "utmost caution" as ties deteriorate after each nation expelled one of the other's diplomats in an escalating row over the murder of a Sikh separatist leader.

Tension has grown since Prime Minister Justin Trudeau said on Monday Canada was investigating "credible allegations" about the potential involvement of Indian government agents in the murder of Hardeep Singh Nijjar in British Columbia in June.
