Hardeep Singh Nijjar, 45, was shot dead outside a Sikh temple in Surrey, a Vancouver suburb with a large Sikh population. He was a Canadian citizen who campaigned for the creation of an independent Sikh territory called “Khalistan”, carved out of India.

A Canadian trade official said Canada had suspended negotiations on a proposed trade treaty with India, an unexpected move that came about three months after the two countries announced plans to strike a first pact in 2023.

Prime Minister Narendra Modi expresses serious concerns over Sikh separatist protests in Canada to Prime Minister Trudeau on the sidelines of the G20 summit in New Delhi.

Trudeau told Parliament that Canada was “actively pursuing credible allegations” linking Indian government agents to Nijjar’s killing.

India rejects Trudeau’s claim, calling it “absurd.” Each country expels a diplomat in a tit-for-tat move, with Canada expelling the country’s top Indian intelligence officer while India expels its Canadian counterpart.

India suspends the issuance of new visas to Canadians and asks Ottawa to reduce its diplomatic presence in India. India starts issuing visas again two months later

Canada has withdrawn 41 diplomats from India over a dispute over Nijjar’s killing, Foreign Affairs Minister Mélanie Joly said.

Tens of thousands of Sikhs gather in Surrey, British Columbia, at the same gurdwara, a Sikh place of worship, where Nijjar was killed to vote in an unofficial referendum on the creation of an independent Sikh state .

A senior Biden administration official said U.S. authorities foiled a plot to kill Gurpatwant Singh Pannun, a Sikh separatist, in New York and issued a warning to India over concerns that New York’s government Delhi was involved.

India says it will investigate US concerns linking it to the foiled murder plot in New York.

The White House is calling a Washington Post report that an Indian intelligence officer was directly involved in both Nijjar’s killing and the foiled plot to kill Pannun in the United States a serious matter. India’s foreign ministry said the report contained “unwarranted and baseless imputations.”

Canadian police are charging three people in connection with Nijjar’s murder, according to a source directly familiar with the matter.

Canadian police arrest and charge fourth man in connection with Nijjar’s murder.

Canada expels six Indian diplomats, including the high commissioner, linking them to Nijjar’s murder. India expels six Canadian diplomats in retaliation, rejects allegations and accuses Trudeau of pursuing a “political agenda.”

U.S. and Indian officials met to discuss an investigation into the foiled assassination plot against Pannun, the State Department said, adding that Washington was pleased with India’s cooperation.

The United States accuses a former Indian government official of leading a foiled plot to assassinate Pannun in New York.

A former Indian official indicted by the United States rejects the allegations, his family says.
