The US ​and Israel ‌launched an attack ​on ​the Natanz uranium-enrichment ⁠facility ​on ​Saturday morning, Iran's Tasnim ​news ​agency said, as the war in the Middle East entered its fourth week.

No radioactive ‌leaks ⁠occurred and residents near ​the ​site ⁠were not ​at ​risk, ⁠Tasnim added.

The UN's nuclear watchdog, International Atomic Energy Agency (IAEA) reported that there was "no increase in off-site radiation levels" and that it is looking into the report.

IAEA reiterated its "call for military restraint to avoid any risk of a nuclear accident".

Natanz, the country's main enrichment site, was hit in the first week of the war and several buildings appeared damaged, according to satellite images. The United Nations' nuclear watchdog had said that "no radiological consequence" was expected from that earlier strike.

The nuclear facility, located nearly 220km southeast of Tehran, had been targeted by Israeli airstrikes in the 12-day war between Iran and Israel in June 2025, and by the US.

The 3-week-old war has shown no signs of abating, with Israel saying Iran continued to fire missiles at it early Saturday, while Saudi Arabia said it downed 20 drones in just a couple of hours in the country's eastern region, which is home to major oil installations.

The attacks came a day after Israeli airstrikes hit in Tehran as Iranians celebrated the Persian New Year, known as Nowruz, a normally festive holiday that has been muted by the war, reported Associated Press.

The US and Israel have offered shifting rationales for the war, from hoping to foment an uprising that topples Iran's leadership to eliminating its nuclear and missile programs. There have been no public signs of any such uprising and no end to the war in sight.

On social media, Trump said, "We are getting very close to meeting our objectives as we consider winding down our great Military efforts in the Middle East."

That seemed at odds with his administration's move to bolster its firepower in the region and request another $200 billion from Congress to fund the war.

The US is deploying three more amphibious assault ships and roughly 2,500 additional Marines to the Middle East, an official told The Associated Press. Two other US officials confirmed that ships were deploying, without saying where they were headed. All three spoke on condition of anonymity to discuss sensitive military operations.

The mixed messages from the US came after another climb in oil prices plunged the US stock market, and was followed by a Trump administration announcement it was lifting sanctions on Iranian oil already loaded on ships, a move aimed at wrangling soaring fuel prices.

Meanwhile, Iran fired two intermediate-range ballistic missiles at the Diego Garcia US-UK military base in the middle of the Indian Ocean, according to several US officials.

Neither of the missiles struck the base, but the move marks Iran's first time using such missiles to reach beyond the Middle East. 

Iran has threatened to target officials and military commanders from the US and Israel, and that it would attack recreational and tourist sites worldwide if it had to.

"We are watching your cowardly officials and commanders, pilots and wicked soldiers," armed forces spokesman Abolfazl Shekarchi said, quoted by state TV.

"From now on, based on the information we have on you, the promenades, resorts and tourist and entertainment centres in the world will not be safe for you either".

The latest developments are an incidation that the war does not show any signs of de-escalating, with attacks continuing across the region.
