Information shared by members of an intelligence-sharing alliance was part of what Canadian Prime Minister Justin Trudeau used to make public allegations of the Indian government's possible involvement in the assassination of a Sikh Canadian, the U.S. ambassador to Canada said.

“There was shared intelligence among ‘Five Eyes’ partners that helped lead Canada to (make) the statements that the prime minister made,” U.S. Ambassador David Cohen told Canadian CTV News network.

CTV News released some of Cohen's comments late Friday, and the network said that it would air the full interview with the U.S. envoy on Sunday. No further details were released about the shared intelligence.
