Iran’s permanent mission to international organizations in Vienna has sharply criticized IAEA Director General Rafael Grossi for applying a clear double standard in his response to attacks on nuclear facilities.

In a statement posted on its X account on Monday, the Iranian mission noted that the phrase “STRONGLY CONDEMNS” is readily used in some cases but was never applied when Iran’s safeguarded peaceful nuclear sites were bombed.

The Iranian delegation highlighted Grossi’s strong condemnation of a drone attack that killed a staff member at Ukraine’s Zaporizhzhia nuclear power plant.

The mission wrote: “It is impressive that the phrase ‘STRONGLY CONDEMNS’ can be used by Grossi. But why is it not applied consistently in all situations?”

Referring to the June 2025 US and Israeli strikes on Iranian nuclear facilities under IAEA safeguards, an act the Agency itself has described as unprecedented in its history, the statement continued: “When US and Israeli regime bombs struck Iran’s safeguarded peaceful nuclear facilities… or the Iranian nuclear personnel were assassinated, they were never condemned. In those situations, DG apparently considered condemnation to fall outside his ‘purview’ and ‘work’.”

The mission described the disparity as “selective outrage,” stating that it “isn’t a pillar of nuclear safety and safeguards. It’s a pillar of a résumé.”

It added that “institutional duty is not optional” and that “professionalism requires consistency.”

Earlier this month, Iran's Vienna mission had slammed the Grossi for repeatedly expressing concern over Iran’s stockpile of uranium enriched to 60 percent while remaining silent on the illegal bombing of facilities that were under continuous IAEA safeguards.

Iranian officials have stressed that the Agency’s own reports never recorded the diversion of even a single gram of nuclear material, and that the NPT sets no ceiling on enrichment levels.

Iran has long argued that the US-Israeli attacks, which also targeted nuclear scientists and personnel, constituted grave violations of the UN Charter, the IAEA Statute, and fundamental nuclear safety principles.

Tehran has repeatedly called on Grossi to fulfill his legal and professional obligations by condemning such acts, warning that selective silence undermines the credibility of the non-proliferation regime and the Agency’s claimed impartiality.

Following the unprovoked Israeli and US aggression against Iran's nuclear facilities,  Iranian officials have repeatedly criticized the IAEA’s failure to respond consistently to attacks on safeguarded facilities.
