United States and Israeli forces launched airstrikes on Iran's Natanz nuclear enrichment facility early Saturday, marking the latest blow to Tehran's atomic program amid the ongoing war.

Iran's Atomic Energy Organization stated that the attack targeted the Shahid Ahmadi Roshan complex but caused no leakage of radioactive materials and posed no risk to nearby residents. The underground core sections remained intact and secure, according to state media reports. The International Atomic Energy Agency confirmed it had been informed of the strike and detected no increase in off-site radiation levels.

The assault follows initial US-Israeli strikes on Natanz during the war's opening days in late February and early March. On March 1, Israel targeted three entrances to the site—two for personnel and one for vehicles—damaging several buildings, as verified by satellite imagery and IAEA assessments. Iran's ambassador to the IAEA, Reza Najafi, accused the US and Israel of attacking the "peaceful, safeguarded" facility on March 1. The UN nuclear watchdog reported no radiological consequences from those hits.

The 2026 Iran war erupted on February 28 when US and Israeli airstrikes hit multiple Iranian targets, including Natanz, as part of Operations Epic Fury and Roaring Lion. The campaign has assassinated key figures, such as Supreme Leader Ali Khamenei and security chief Ali Larijani, and destroyed over 190 ballistic missile launchers and numerous naval vessels. Iran has retaliated with missile and drone barrages on Israel, US bases, and Gulf states, including today's launches at the Diego Garcia base.

Israeli Defense Minister Israel Katz warned that the intensity of US-Israeli attacks on Iran would "significantly escalate" this week, vowing not to halt until objectives are met. US President Donald Trump indicated consideration of winding down operations but rejected a ceasefire. Iran's new Supreme Leader Mojtaba Khamenei claimed his forces delivered a "dizzying blow" to adversaries.

Casualties have mounted, with Iranian sources reporting over 1,400 deaths and human rights groups estimating up to 5,300, mostly military. The conflict has disrupted the Strait of Hormuz, spiked oil prices above $114 per barrel, and drawn in Hezbollah, with over 1,000 killed in Lebanon. IAEA Director General Rafael Grossi urged restraint to prevent nuclear accidents.

Natanz, 220 kilometers south of Tehran, has long been central to Iran's uranium enrichment, previously targeted in a 2025 Israel-Iran clash. The site mixes above- and below-ground facilities, with the US and Israel aiming to curb Tehran's nuclear advances.
