  In the early hours of 13 June 2025, the IDF attacked dozens of Iranian nuclear facilities, military bases and infrastructure installations, and key military commanders, including some targets, Israeli officials said, that were not anticipated by Tehran. By 06:30 IDT, the Israeli Air Force (IAF) had launched five waves of air strikes, using more than 200 fighter jets to drop more than 330 munitions on about 100 targets. The fighter jets included multiple F-35I Adir fighters, the Israeli variant of the American F-35 Lightning II stealth strike fighter. The F-35I's were reportedly modified with low-observable conformal fuel tanks to enable them to have the range and endurance to conduct operations over Iran without compromising stealthy characteristics or requiring mid-air refueling. Israeli targets included the Natanz Nuclear Facility and other infrastructure of Iran's nuclear program. No nuclear accidents occurred as a result of the airstrikes, as operational nuclear reactors, such as the Bushehr Nuclear Power Plant and the Tehran Research Reactor, were not attacked. Although damaged nuclear centrifuges can release low-level radiation and industrial chemicals that can threaten on-site personnel, they can neither trigger nuclear explosions nor cause large-scale contamination of an area.
  
  Meanwhile, the Mossad sabotaged Iran's air defense systems and missile infrastructure. An Israeli official said the Mossad had smuggled precision weapons and established a covert drone base near Tehran, which were used to disable air defenses, securing air superiority for Israeli aircraft.
  
  Around 03:00 local time, Israeli Defense Minister Israel Katz declared a nationwide state of emergency, warning of an imminent missile and drone retaliation. Warning sirens were activated across Israel in anticipation of a possible Iranian counterattack, though Iran would launch no ballistic missiles until the following evening. Katz further described Israel's attack on Iran as a "preemptive strike". According to the IDF, the action was prompted by intelligence indicating Iran had amassed enough enriched uranium that they would be able to further enrich it to weapons grade in an amount sufficient for 15 nuclear weapons in a matter of days. However, estimates of the time required to make an actual weapon varied from 7 to 12 months at the time of the IDF's statement.
  
  Explosions were reported across Tehran, including near military bases and in neighborhoods housing senior commanders. Eyewitnesses described enormous flames and repeated blasts. Fars News Agency, which is linked to the IRGC, reported that multiple homes were struck in Shahrak-e Mahallati, a neighborhood in eastern Tehran where high-ranking Iranian military officers and their families reside. The attack reportedly set on fire the IRGC headquarters in Tehran. Some residential complexes were hit during the attack, including ones that housed Iranian officers and officials. Reportedly, the strength of the explosions caused some buildings to collapse.
  
  Blasts were reported at the Natanz Nuclear Facility, in Isfahan province, where one of Iran's most critical nuclear facilities is located. Iranian state TV confirmed "loud explosions" near the site, which houses two enrichment plants: the large underground Fuel Enrichment Plant (FEP) and the Pilot Fuel Enrichment Plant (PFEP) above ground. Nuclear sites at Khondab and Khorramabad were also targeted.
