Nearly a month after Canadian Prime Minister Justin Trudeau levelled allegations of a potential link between Indian government agents and the death of terrorist Hardeep Singh Nijjar, Australia's domestic intelligence chief has said he has "no reason to dispute" Canada's claims. 

The remarks by Mike Burgess, Director of the Australian Security Intelligence Organisation (ASIO), in California, on the sidelines of a historic public gathering of Five Eyes intelligence partners, came after he was asked for his assessment of Canada's allegations. 

India had rejected the accusations as "absurd" and expelled a senior Canadian diplomat in response.

"No reason to dispute what the Canadian government has said in this matter," ABC News quoted Burgess as saying. 

"There's no doubt any allegation of any country being accused of carrying out an execution of a citizen in that country, it's a serious allegation, and something that we don't do and something that nations should not do," he added.

The report also quoted a source and stated Burgess was briefed on the matter before last month's G20 summit in New Delhi.

India and Canada are in the midst of a diplomatic row that erupted following Canadian Prime Minister Justin Trudeau's allegation linking Indian agents to Nijjar's killing on June 18.

Nijjar, whom India designated a terrorist in 2020, was shot dead by two masked gunmen in British Columbia.
