The Israel Defense Forces (IDF) announced overnight (Saturday to Sunday) that it had completed a large-scale wave of airstrikes in Tehran, targeting infrastructure of Iran's nuclear project and fuel depots.

According to the statement, Israeli Air Force (IAF) fighter jets, guided by intelligence from the IDF Intelligence Directorate, struck multiple targets associated with Iran’s nuclear weapons program. These included the Iranian Ministry of Defense headquarters, the SPND (Organization of Defensive Innovation and Research) headquarters, and additional related targets.

During the night, Iranian sources told The New York Times that Israel had attacked the central fuel terminal in northern Tehran, resulting in a series of explosions. Residents reported that fuel storage tanks exploded one after another, creating a “giant fireball” and smoke visible across northern Tehran.

SPND, whose headquarters was bombed during the night, is the agency responsible for the research and development of military and nuclear weapon technologies. It was formerly headed by Mohsen Fakhrizadeh, dubbed the “father of Iran’s nuclear program,” who was assassinated by the Mossad in 2021.

As part of Operation "Am K’Lavi" (Operation Rising Lion), the Israeli Air Force also bombed the Natanz nuclear facility, Iran’s main uranium enrichment site. According to the Air Force, the Natanz facility suffered “significant damage, though not yet classified as destruction.” The IDF also announced it had targeted nuclear elements related to "reconversion" at the Isfahan conversion facility, though that site has not been destroyed. The Fordow facility was not targeted.

The attack began with strikes on senior Iranian regime officials, top nuclear scientists, command centers, surface-to-surface missile platforms, and air defense systems—aimed at degrading Iran’s air defense network and enabling continued strikes.
