US authorities may sue a former American special forces member who has written a first-hand account of the raid that killed Osama bin Laden.
The Pentagon's top lawyer has informed the former US Navy Seal that he has violated agreements not to divulge military secrets.
He signed two non-disclosure forms with the Navy in 2007, the Pentagon said.
The book No Easy Day which was written under the pseudonym Mark Owen, is due to be released next week, the BBC reports.
It has been reported that the book contradicts the official story of the May 2011 raid.
It was not reviewed ahead of publication by the Pentagon, CIA or the White House and officials had warned that criminal charges could result from the improper disclosure of secret information.
