Biden 'deeply concerned' over leaked intel on Israeli plans to retaliate against Iran: White House

President Joe Biden is deeply concerned about the unauthorized release of classified documents detailing Israel’s plans for a potential retaliatory attack on Iran.

The top-secret documents dated October 15 and 16 were posted on Telegram by the “Middle East Spectator” account and began circulating online last Friday. These documents were marked for viewing by only the US and its “Five Eyes” allies (Australia, Canada, New Zealand, and the UK.

The administration was still not certain if the classified information that became publicly disclosed was leaked or hacked, White House national security spokesman John Kirby said on Monday.

Kirby added that administration officials don’t have any indication at this point of ”additional documents like this finding their way into the public domain.” He added the Pentagon is investing the matter.

“We’re deeply concerned and the president remains deeply concerned about any leakage of classified information into the public domain. That is not supposed to happen and it’s unacceptable when it does,” Kirby said.

The documents are attributed to the National Geospatial-Intelligence Agency and National Security Agency, and 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.
