Canadian authorities have charged a fourth Indian national in connection with the 2023 murder of Hardeep Singh Nijjar, a prominent Sikh leader in Vancouver. Amandeep Singh, 22, was arrested and charged with first-degree murder and conspiracy to commit murder, adding to the ongoing investigation that has strained relations between Canada and India. Nijjar, who advocated for a separate Sikh state known as Khalistan, was shot dead in June 2023, sparking allegations of Indian intelligence involvement.
