The United States has expressed deep concern over allegations made by Canadian Prime Minister Justin Trudeau that India was involved in the June 18 murder of Sikh activist and leader Hardeep Singh Nijjar. Secretary of State Antony Blinken has called for both Canada and India to work together to investigate the possible involvement of New Delhi agents in the murder, and the Indian government has denied the allegations. The U.S. is also calling for a full and transparent investigation into the matter.
