Foreign Ministry spokesman Esmaeil Baghaei told Al Jazeera that Grossi’s earlier remarks had paved the way for acts of aggression by the United States and the Israeli regime against Iran in June.
He said the IAEA chief should avoid expressing unfounded opinions about Iran’s nuclear activities.
Grossi said on Wednesday that the agency had recently detected renewed movement at Iran’s nuclear sites, while acknowledging that the country did not appear to be actively enriching uranium.
He added that despite limited access to Iranian nuclear sites, inspectors had not seen any satellite evidence suggesting Tehran had increased uranium enrichment beyond levels recorded before the 12-day war with Israel in June.
In a confidential report to the IAEA Board of Governors on May 31, 2025, Grossi claimed that Iran had not reported activities at three undeclared locations and raised concerns over its uranium stockpile enriched up to 60% purity.
The Atomic Energy Organization of Iran (AEOI) said in response that including irrelevant issues in the report contradicted the agency’s professionalism, objectivity, and impartiality.
“Sixty-percent uranium enrichment is not prohibited under the [Nuclear Non-Proliferation Treaty] NPT, and Iran’s 60% enrichment and stockpiles are fully under the agency’s monitoring and verification,” the AEOI said.
It added that all of Iran’s nuclear materials and activities had been fully declared to and verified by the IAEA.
On June 13, Israel launched an unprovoked war against Iran, killing senior military commanders, nuclear scientists, and civilians.
More than a week later, the United States entered the war, bombing three Iranian nuclear sites in a grave violation of the UN Charter, international law, and the NPT.
Prior to the unprovoked war, Iran had warned the IAEA against politically motivated actions that could undermine its cooperation with the UN nuclear watchdog.
Iranian officials say Grossi’s report on Tehran’s nuclear program paved the way for Israel’s aggression on the Islamic Republic.
In late June, Iran’s Constitutional Council approved a parliamentary bill to suspend cooperation with the IAEA.
The bill cites violations of Iran’s sovereignty and attacks on its nuclear facilities and vital interests, mandating the government to halt all cooperation with the agency.
Iranian President Masoud Pezeshkian told European Council President António Costa on July 9 that Tehran would resume cooperation with the IAEA if double standards on its nuclear program were abandoned.
