The investigation into the leak of Israeli preparations for a possible attack on Iran continues

The FBI confirmed the investigation Tuesday and said the Defense Department and intelligence community were assisting, but had no further comment in a prepared statement issued Tuesday.

The National Security Agency and the National Geospatial-Intelligence Agency produced the two documents, which were dated October 15 and 16.

National Security Council spokesman John Kirby confirmed Monday that the documents had been released and said there was no information to suggest that additional documents were compromised or might be released.

Federal investigators suspect that someone with internal access to the documents leaked them, rather than someone obtaining them online through cyber espionage.

Published on Friday on a Telegram account called the Middle East Spectator, they cover in a document how Israel moves its ammunition and Israeli Air Force exercises involving air-to-surface missiles.

A Sky News Arabic report published on Tuesday named a senior aide in Defense Secretary Lloyd Austin's office as the source of the leaked documents, but Pentagon officials denied she was interested in the investigation.

Ariane Tabatabai is an Iranian-American and Chief of Staff to the Assistant Secretary of Defense for Special Operations. It is not the subject of interest in the allegations of leaked classified documents, a Pentagon official said Tuesday.

“To my knowledge, this official is not a subject of interest,” Air Force press secretary Maj. Gen. Pat Ryder told media Tuesday afternoon.

Ryder said the FBI is investigating the “alleged loss” of classified documents and is working with the Defense Department and intelligence officials.

Tabatabai is the Curriculum Director and Visiting Professor of Security Studies at the Edmund A. Walsh School of Foreign Service at Georgetown University.
