Iran yesterday dismissed the UN nuclear watchdog's work as "unprofessional" and "unfair" shortly before the two sides are due to hold talks aimed at resolving a standoff over the origin of uranium particles found at old but undeclared sites in Iran, Reuters reports.
"The statement of the Agency in its report is completely unprofessional, illusory and unfair," Iran's ambassador to the International Atomic Energy Agency (IAEA), Kazem Gharibabadi, said in a statement to a meeting of the IAEA's 35-nation Board of Governors.
Gharibabadi was referring to a passage in an IAEA report last week that said the lack of progress was seriously affecting the IAEA's ability to determine that Iran's programme is entirely peaceful, as Tehran says it is.
Failure to resolve the issue complicates efforts to restart talks aimed at bringing the United States and Iran fully back into the fold of the 2015 nuclear deal, which Washington unilaterally withdrew from in 2018.
Having obtained concessions last weekend from Iran on another issue, keeping some monitoring equipment running, IAEA chief Rafael Grossi is due to meet Iranian nuclear chief Mohammad Eslami in Vienna next week for talks on the particles.
To Iran and allies like Russia, the fact the three sites mainly seem to date back to the early 2000s and there is no indication any of the material present was enriched to a high degree means the world and the IAEA should move on.
The IAEA, however, seeks to account for all nuclear material in a country. The traces suggest some material might still exist and be unaccounted for, meaning it could potentially be used to make nuclear weapons.
"I would like to seriously convey my concerns over the aggrandizing of few insignificant old issues from the (IAEA) secretariat," Gharibabadi said in the text of his statement.
"How is it possible that an insignificant amount of material belonging to two decades ago affect the peaceful nature of the nuclear program of a country, while that country is hosting more than 20 percent of the Agency's inspections at the global level … ?!" he added.
This comes after the IAEA on Tuesday described as "unacceptable" incidents in Iran involving its inspectors, in which diplomats say security staff subjected female inspectors to inappropriate searches that the United States is calling harassment. Iran rejects the claims with it Gharibabadi tweeting: "Security measures at the nuclear facilities in Iran are, reasonably, tightened. The IAEA inspectors have gradually come up with the new rules and regulations."
