Iranian Leaders Were Caught Off Guard by Hamas Attack on Israel

Iranian Leaders Were Caught Off Guard by Hamas Attack on Israel.

The United States has collected multiple pieces of intelligence that show that key Iranian leaders were surprised by the Hamas attack in Israel, information that has fueled U.S. doubts that Iran played a direct role in planning the assault, according to several American officials.

These key Iranian officials did not know the attack was coming, according to the intelligence. The United States, Israel and key regional allies have not found evidence that Iran directly helped plan the attack, according to the U.S. officials and another official in the Middle East.

While they would not identify the Iranian officials who expressed surprise at the attack, the U.S. officials said they were people who typically would be aware of operations involving the Quds Force, Iran's paramilitary arm that supports and works with proxy forces.

U.S. officials said the intelligence investigation was continuing and could turn up evidence that Iran or other states were directly involved in the Hamas operation. Senior officials said they were keeping an open mind, reviewing old intelligence reports and looking for new information.

Iran has provided large numbers of weapons and support to Hamas over many years. U.S. officials have made clear that they believe this makes Tehran broadly complicit in the attack. But that was a different issue than direct knowledge and involvement, they said.

Morgan Muir, a senior U.S. intelligence official, told members of Congress in a briefing on Tuesday that there was no direct link between Iran and the Hamas attack, U.S. officials said. Mr. Muir provided few details but told lawmakers that U.S. agencies had intelligence contradicting assertions that Iran had helped plan the attack.

The United States and its allies regularly track and monitor meetings between Quds Force leaders and their proxies and allies, including Hamas. But officials say there is no evidence that those meetings were used to plan the attack in Israel. While officials concede that there could have been other secret meetings that Western intelligence did not track, for now they have found no evidence of such meetings.

The U.S. officials spoke on the condition of anonymity to discuss the intelligence and requested that The New York Times not report the means of collection to protect sources and methods.

Jake Sullivan, the national security adviser, said on Tuesday that agencies had not collected intelligence about direct Iranian involvement in the attack.

Officials said Mr. Sullivan’s remarks reflected the intelligence collected so far, which did not point to direct involvement by Iran.

“We have said since the beginning: Iran is complicit in this attack in a broad sense because they have provided the lion’s share of the funding for the military arm of Hamas,” he said. “They have provided training, they have provided capabilities.”
