Canada’s allegations against Union home minister Amit Shah are “concerning”, the US said on Wednesday, noting that it would continue to consult Ottawa on the matter.

“The allegations made by the government of Canada are concerning, and we will continue to consult with the Canadian government about those allegations,” state department spokesperson Matthew Miller told reporters at his daily news conference.

Canada’s national security and intelligence adviser Nathalie Drouin and deputy foreign affairs minister David Morrison, members of the national security committee of the Canadian parliament, on Tuesday confirmed leaked Washington Post reports alleging that Shah was behind the campaign of targeting Khalistani separatists in Canada.

Morrison said he had confirmed this to a correspondent of The Post when asked a specific question on whether Shah was involved, against the backdrop of ties hitting an all-time low after Ottawa named six Indian diplomats in Canada as “persons of interest” in Khalistani separatist Hardeep Singh Nijjar’s murder.

Asked about the circumstances in which he provided this information to The Post, Morrison said: “The journalist called me and asked if it was that person (Shah). I confirmed it was that person.” He provided no further details on how Shah was linked to the case.
