White House deputy national security adviser Jon Finer led a U.S. delegation to New Delhi on Monday where he noted the formation of an investigative panel by India to probe an unsuccessful plot to assassinate a Sikh separatist on U.S. soil.

"Mr. Finer acknowledged India's establishment of a Committee of Enquiry to investigate lethal plotting in the United States and the importance of holding accountable anyone found responsible," the White House said in a statement on Monday.

Last week, the U.S. Justice Department alleged that an Indian government official directed an unsuccessful plot to assassinate a Sikh separatist on U.S. soil, while it announced charges against a man accused of orchestrating the attempted murder.
