World leaders deeply concerned' over Canada's allegations of India link in death of Khalistani activist

World leaders have expressed 'deep concerns' after Canadian Prime Minister Justin Trudeau made allegations regarding the Indian government’s involvement in the fatal shooting of Khalistan Tiger Force chief Hardeep Singh Nijjar in Canada.

The White House is "deeply concerned" about the accusations, said a spokesman for the National Security Council, Adrienne Watson, according to CNN.

“We remain in regular contact with our Canadian partners. It is critical that Canada’s investigation proceed and the perpetrators be brought to justice,” Watson said.

No one has been arrested by Canadian authorities in relation to Nijjar's killing. However, in an update in August, police said they were looking into three individuals and provided a description of a potential getaway car while pleading with the public for assistance, CNN reported.

The claims have "deeply concerned" Australia as well, according to a spokesperson for Penny Wong, the foreign minister of Australia.

“We are closely engaged with partners on developments. We have conveyed our concerns at senior levels to India,” a statement shared with CNN said.
