The United States is investigating a leak of classified documents related to Israeli military plans. The documents in the unauthorized release assess Israel’s plans to attack Iran. They note that Israel continues to move military assets in place to conduct a military strike in response to Iran’s ballistic missile attack earlier this month. It was not initially known if the documents were leaked or hacked. The information appeared entirely gathered through the use of satellite image analysis. A U-S official told The Associated Press that the top secret documents appear to be legitimate.
