Iranian state media confirmed Tuesday that Ali Larijani, secretary of Iran’s Supreme National Security Council, is dead, hours after Israel said he and another senior official were killed in overnight airstrikes.

“Ali Larijani, Secretary of the Supreme National Security Council, has been martyred,” the Fars News Agency reported on social media.

Iran’s Islamic Revolutionary Guard Corps (IRGC) also confirmed that Gholamreza Soleimani, the commander of the IRGC’s internal security militia known as Basij, has been killed in the strikes.

Larijani is the second most senior Iranian official to be assassinated since Ayatollah Ali Khamenei was killed in targeted strikes on his compound on the first day of the joint U.S.-Israeli campaign.

The U.S. and Israel launched what they described as a pre-emptive strike against Iran on February 28, claiming that Tehran was developing a nuclear weapon and posed a threat—an allegation Iran has denied. In response, Iran launched counterattacks, firing missiles and drones at Israel, as well as at U.S. assets and other targets across the Middle East.
