US investigating release of classified docs on Israel's preparations for possible Iran strike

The United States is investigating the unauthorized release of classified documents describing Israel's preparations for a possible attack against Iran, The Associated Press reported.

The documents, attributed to the U.S. Geospatial Intelligence Agency and National Security Agency, note that Israel was still moving military assets in place to conduct a military strike in response to Iran's blistering ballistic missile attack on Oct. 1. They were sharable within the "Five Eyes," which are the U.S., Great Britain, Canada, New Zealand and Australia.

The documents, which are marked top secret, were posted to the Telegram messaging app last week and first reported by CNN and Axios. The AP first reported Sunday about the U.S. investigation into the unauthorized release, citing three U.S. officials. The AP said a fourth U.S. official, who also spoke on condition of anonymity, indicated that the documents appeared to be legitimate. 

House Speaker Mike Johnson, R-La., also confirmed the investigation in an appearance on CNN. 

"The leak is very concerning. There's some serious allegations being made, there's an investigation underway, and I'll get a briefing on that in a couple of hours," Johnson said Sunday on CNN's "State of the Union." "There's a classified level briefing and then another. But we're following it closely."

The investigation is also examining how the documents were obtained - including whether it was an intentional leak by a member of the U.S. intelligence community or by another method, like a hack - and whether any other intelligence information was compromised, one of the officials told the AP, adding that officials are working to determine who had access to the documents before they were posted.
