NEW DELHI (Reuters) - Trade talks between India and Canada have taken a hit as tension rises after Prime Minister Justin Trudeau said authorities were investigating "credible allegations" linking New Delhi's agents to the murder of a Sikh separatist leader.

On Tuesday, New Delhi dismissed the allegations as "absurd", and asked Canada instead to crack down on anti-India elements operating in its territory.
