Iran has accused the US of violating international law and the Nuclear Non-Proliferation Treaty (NPT) following overnight airstrikes on three of its key nuclear facilities. However, Tehran says preliminary inspections have found no signs of radioactive contamination.

In a statement issued early on Sunday, the Atomic Energy Organization of Iran (AEOI) confirmed that US strikes targeted its nuclear sites at Fordow, Natanz, and Isfahan. The operation, conducted in coordination with Israel, was condemned by the Iranian authorities as an illegal and “brutal” act.

“This act of aggression was carried out under the shadow of international indifference, and with the apparent support or silence of the International Atomic Energy Agency,” the AEOI said.

Iran’s Center for the National Nuclear Safety System reported that emergency inspections had been completed at all three locations. “No signs of contamination have been recorded,” the agency said, adding that there is “no danger to residents living near the affected sites.”

Iran vowed that its nuclear program will not be derailed. “We will not allow this national industry – built through the sacrifices of our nuclear martyrs – to be stopped by evil conspiracies,” the AEOI said, promising legal action over the strikes.

Washington has not formally responded to the accusations of NPT violations. President Donald Trump, who confirmed US involvement in the attacks, warned Iran against retaliating, saying further strikes would follow any response.

The strikes mark a dramatic escalation in the already volatile tensions between Iran and Israel. The Israel Defense Forces (IDF) described the joint offensive as targeting Iran’s missile and nuclear infrastructure.

Iranian officials maintain that its nuclear program is entirely peaceful and under the oversight of international inspectors. The International Atomic Energy Agency has not reported any current evidence of an Iranian nuclear weapons program.

The incident has sparked fears of further regional instability, with Iran accusing the US of undermining global non-proliferation norms. As of Sunday afternoon, Tehran had not announced any military response.
