Iran has officially suspended its cooperation with the United Nations' nuclear watchdog, the International Atomic Energy Agency (IAEA), just days after a ceasefire ended a 12-day conflict marked by Israeli and US strikes on Iranian nuclear facilities.

The decision follows a parliamentary vote on June 25—one day after the ceasefire—which overwhelmingly supported a bill to end cooperation with the IAEA. The legislation was later approved by the Guardian Council and ratified by President Masoud Pezeshkian.

“Iranian President Masoud Pezeshkian promulgated the law suspending cooperation with the International Atomic Energy Agency,” state television confirmed on Wednesday (July 2).

Tehran has sharply criticised the IAEA, accusing it of remaining silent in the face of attacks on its nuclear sites and condemning a June 12 agency resolution that accused Iran of failing to meet its nuclear obligations. Iranian officials argue that the resolution provided justification for the Israeli strikes.

Iran has denied IAEA Director General Rafael Grossi's request to inspect bombed nuclear facilities, with President Pezeshkian recently calling Grossi's actions “destructive.” While Iran insists it has not threatened Grossi or IAEA inspectors, tensions remain high.

State media and hardline publications, including the Kayhan newspaper, have gone as far as accusing Grossi of espionage and calling for severe punishment.

Foreign ministry spokesperson Esmaeil Baqaei said on Monday that the move to end cooperation reflects “the concern and anger of the Iranian public.” Meanwhile, European nations, including France, Germany, and the UK, have expressed alarm over threats against the IAEA chief.
