Canada's investigation into alleged Indian involvement in the assassination of a Sikh separatist in Vancouver last year is a "political compulsion", New Delhi's foreign minister said after three Indian citizens were arrested over the killing.
Canadian police on Friday arrested the trio for the murder of Hardeep Singh Nijjar, saying they were investigating their links to the Indian government, "if any".
The killing sent diplomatic relations between Ottawa and New Delhi into a tailspin last autumn after Prime Minister Justin Trudeau said there were "credible allegations" linking Indian intelligence to the crime.
India vehemently rejected the allegations as "absurd", halting the processing of visas for a time and forcing Canada to significantly reduce its diplomatic presence in the country.
"It is their political compulsion in Canada to blame India," the Press Trust of India news agency quoted external affairs minister S. Jaishankar as saying on Saturday.
Thousands of people were killed in the 1980s during a separatist insurgency aimed at creating a Sikh homeland known as Khalistan, which was put down by security forces.
The movement has largely petered out within India, but in the Sikh diaspora -- whose largest community is in Canada, with around 770,000 people -- it retains support among a vocal minority.
New Delhi has sought to persuade Ottawa not to grant Sikh separatists visas or political legitimacy, Jaishankar said, since they are "causing problems for them (Canada), for us and also for our relationship".
He added that Canada does not "share any evidence with us in certain cases, police agencies also do not cooperate with us".
Nijjar immigrated to Canada in 1997 and acquired citizenship 18 years later. He was wanted by Indian authorities for alleged terrorism and conspiracy to commit murder.
The three arrested Indian nationals, all in their twenties, were charged with first degree murder and conspiracy.
They were accused of being the shooter, driver and lookout in his killing last June.
The Canadian police said they were aware that "others may have played a role" in the murder.
In November, the US Justice Department charged an Indian citizen living in the Czech Republic with plotting a similar assassination attempt on another Sikh separatist leader on American soil.
A Washington Post investigation reported last week that Indian foreign intelligence officials were involved in the plot, a claim rejected by New Delhi.
Canada PM hails 'rule of law' after arrests in Sikh separatist murder
Prime Minister Justin Trudeau on Saturday acknowledged fear in Canada's Sikh community but underscored the "rule of law" after three arrests in connection with last year's killing of a Sikh separatist in Vancouver.
Police arrested three men on Friday for the murder of Hardeep Singh Nijjar, which triggered a diplomatic rift between Canada and India last fall after Trudeau suggested Indian government involvement in the homicide.
Speaking Saturday at a gala in Toronto to celebrate Sikh heritage and culture, Trudeau acknowledged that many in Canada's Sikh community are "feeling uneasy, and perhaps even frightened right now," but urged faith in the justice system.
"Let us remain calm and us remain steadfast in our commitment to our democratic principles and our system of justice," he said.
Trudeau said the arrests were "important because Canada is a rule of law country with a strong and independent justice system, as well as a fundamental commitment to protecting all its citizens."
Three Indian nationals, two aged 22 and one aged 28, were arrested Friday on first-degree murder and conspiracy charges.
They are accused of being the shooter, driver and lookout on the day Nijjar was killed.
Police said they were still investigating the ties of the suspects, "if any, to the Indian government," and whether others may have been involved.
Nijjar -- who immigrated to Canada in 1997 and became a citizen in 2015 -- advocated for a separate Sikh state, known as Khalistan, carved out of India.
He was wanted by Indian authorities for alleged terrorism and conspiracy to commit murder.
On June 18, 2023, he was shot dead by masked assailants in the parking lot of the Sikh temple he led in suburban Vancouver.
Trudeau announced several months later that Canada had "credible allegations" linking Indian intelligence to the killing and expelled an Indian official, touching off a diplomatic tit-for-tat with New Delhi.
India dismissed the allegations as "absurd" and responded furiously, briefly curbing visas for Canadians and forcing Ottawa to withdraw diplomats.
In November, the US Justice Department charged an Indian citizen living in the Czech Republic with allegedly plotting a similar assassination attempt on American soil.
