NEW YORK  — Publication has been halted for a disputed book about the attack last year on a U.S. mission in Benghazi, Libya.

Threshold Editions announced Friday it has withdrawn Dylan Davies’ “The Embassy House: The Explosive Eyewitness Account of the Libyan Embassy Siege by the Soldier Who Was There” after serious doubts emerged about whether Davies had witnessed the 2012 raid.

“In light of information that has been brought to our attention since the initial publication of ‘The Embassy House,’ we have withdrawn from publication and sale all formats of this book, and are recommending that booksellers do the same,” according to a statement from Threshold spokesperson Jennifer Robinson. “We also are notifying accounts that they may return the book to us.”

Earlier Friday, CBS News said it had been misled by Davies, a source for a “60 Minutes” broadcast on the attack that aired Oct. 27. Davies’ book was written under the pseudonym “Sergeant Morgan Jones.” Co-authored by Damien Lewis, “Embassy House” was published Oct. 29 and ranked No. 4,931 on Amazon.com as of midday Friday. According to Robinson, 35,000 copies are in print.

Threshold is a conservative imprint of Simon & Schuster that has also released books by Dick Cheney, Karl Rove and Glenn Beck.
