UN Nuclear Inspectors Depart Tehran As Iran Vows To Keep Enriching

A group of inspectors from the United Nations’ nuclear watchdog has finally and formally departed Iran after the country decided to halt its cooperation with the agency, following last month’s surprise bombing raids by Israel and the United States.

The International Atomic Energy Agency (IAEA) confirmed in statement shared on X on Friday that its personnel are returning to the agency’s headquarters in Vienna, Austria. 

Al Jazeera’s Resul Serdar, reporting from Tehran, clarified that it’s as yet unclear just how many IAEA inspectors left the country in this ‘final’ wave of departures.

“The language used doesn’t clarify whether all or only some of the staff departed, but it appears that a number of them are still in Iran,” he said.

IAEA Director-General Rafael Grossi has urged Iran to resume monitoring and verification efforts as soon as possible, saying it is of “crucial importance” that direct dialogue with Tehran continues.

“The inspectors have been housed in Tehran unable to visit Iran’s nuclear sites since Israel attacked the country on June 13,” The Wall Street Journal details. “They were housed at a hotel in the capital but may have later moved to a U.N. location, according to one of the people.”

All of this comes after the Trump White House has threatened the potential for more military action should Iran resume enrichment of uranium, which it has promised to do undeterred. According to more from WSJ:

Their departure makes the prospect of any significant international access to Iran’s nuclear sites extremely unlikely, allowing it to carry out nuclear work unchecked. Iran’s activities are, however, being watched closely by Western and Israeli intelligence agencies, and the IAEA has access to satellite imagery of its sites. It also raises the prospect of a standoff over Iran’s participation in the Non-Proliferation Treaty, which bans it from nuclear weapons and requires regular inspections of its atomic program. 

For decades, Iran has been subject to rigorous inspections of its core nuclear sites. Inspectors would visit its enrichment sites and check its stockpile of enriched uranium every couple of days, ensuring that Iran wasn’t diverting fissile material for a nuclear weapon.

Iran has meanwhile said that while it doesn’t plan to retaliate further against the United States, it will carry on peaceful nuclear energy activities as a matter of national sovereignty. “As long as there is no act of aggression being perpetrated by the United States against us, we will not respond again,“ Deputy Foreign Minister Majid Takht-Ravanchi told NBC News on Thursday.

“Our policy has not changed on enrichment,” Takht-Ravanchi crucially added. “Iran has every right to do enrichment within its territory. The only thing that we have to observe is not to go for militarization.”
