The U.S. takes very seriously the allegations against an Indian government official who is accused of directing an unsuccessful plot to assassinate a Sikh separatist on U.S. soil, White House national security spokesman John Kirby said on Thursday.

Federal prosecutors in Manhattan said Nikhil Gupta, 52, worked with the Indian government employee, whose responsibilities included security and intelligence, on the plot to assassinate the New York City resident who advocated for a sovereign Sikh state in northern India.
