This is the best summary I could come up with:
The report in the Financial Times says U.S. prosecutors have filed a sealed indictment in the case and are debating whether or not to make it public amid Canada's own ongoing investigation into the killing of Hardeep Singh Nijjar in Surrey, B.C.
These allegations threaten to rattle India-U.S. relations at a sensitive geopolitical moment: Washington, embroiled in a rivalry with China, is keen to cultivate ties with India.
It said the target was Gurpatwant Singh Pannun, an American and Canadian citizen who is general counsel for the separatist group Sikhs for Justice.
The paper reports that the U.S. began informing allies about the thwarted plot to kill Pannum after the assassination in Canada, of Nijjar, in June.
It says the U.S. shared details of the case with a wider group of allies after Prime Minister Justin Trudeau went public with his concerns in September.
The paper said Pannum further angered Indian officials this month by issuing a video in which he warned Sikhs not to fly on Air India because it would be "life threatening".
