The head of the United Nations’ nuclear watchdog said this week that the interim US-Iran Peace Agreement grants international inspectors access to Tehran’s nuclear sites, a claim that has reignited friction between Washington and Iran just as both sides attempt to stabilize a fragile ceasefire following months of conflict.
Rafael Grossi, Director General of the International Atomic Energy Agency, told reporters in Tokyo that the memorandum of understanding signed by the US and Iran explicitly places the nuclear component of the deal under IAEA supervision. “In order to supervise, we need to inspect. There is no other way,” Grossi said, adding that technical groundwork for renewed inspections has already begun.
His comments came shortly after former President Trump claimed that Iran had “fully and completely” agreed to allow nuclear inspectors back into the country, an assertion Tehran has firmly denied. Iranian officials maintain that any decision on inspections will only be finalized once a comprehensive agreement is reached, not under the terms of the current interim arrangement.
The US and Iran signed their fourteen point interim agreement last week in an effort to end a war that has stretched on for nearly four months. Under its terms, both nations agreed to halt hostilities, including the proxy conflict between Israel and Hezbollah in Lebanon, and to reopen the Strait of Hormuz toll free for at least sixty days. The strait, one of the world’s most critical oil shipping corridors, had been a flashpoint throughout the conflict after vessels came under attack in the Gulf.
The agreement also calls for Iran to dilute its stockpile of highly enriched uranium in exchange for the US lifting sanctions on Iranian oil exports. Both sides were given a sixty day window to negotiate the finer details of a lasting settlement.
Despite the signed memorandum, the two governments have offered contradictory accounts of what was actually agreed regarding nuclear oversight. Iranian deputy foreign minister Kazem Gharibabadi pushed back directly on Grossi, saying inspection matters “will be reviewed and decided only within the framework of a final agreement,” and accused Washington of using “media hype” to pressure Tehran.
Grossi acknowledged the discrepancy, describing it as a “war of words” between the two capitals, but insisted the written memorandum, not public statements, would govern what happens next.
Since Israel’s twelve day war on Iran in 2025, the IAEA has been barred from visiting Iran’s uranium enrichment facilities, the sites considered most sensitive to nonproliferation concerns. Inspectors have been permitted limited access to other facilities, including the Bushehr nuclear power plant, but without entry to the enrichment sites, the agency says it cannot verify the true status of Iran’s uranium stockpile or inspect the centrifuge cascades used to enrich it.
Iran is the only country in the world known to have enriched uranium to 60 percent purity without an acknowledged weapons program, a level well above what is needed for civilian energy use. Nonproliferation analysts have warned that Tehran’s stockpile, believed sufficient for as many as ten nuclear weapons if further enriched, may have been relocated to undeclared locations during the conflict, making renewed and unrestricted access a central demand for the international community.
The dispute echoes long running tensions over Iran’s nuclear ambitions that date back to the 2015 Joint Comprehensive Plan of Action, the Obama era nuclear deal that Trump withdrew from during his first term, calling it inadequate.
Technical level talks between US and Iranian negotiators are expected to resume at the Bürgenstock resort in Switzerland, with Pakistan continuing to serve as a key mediator between the two sides. US Secretary of State Marco Rubio has also been touring the Gulf region, beginning with meetings in Abu Dhabi, as Washington works to keep regional partners aligned behind the ceasefire.
The truce remains precarious. Lebanon saw renewed fighting between Israeli forces and Iran backed Hezbollah militants this week, and Iran briefly moved to close the Strait of Hormuz again amid the violence, though the situation did not escalate further. For now, both Washington and Tehran appear committed to the sixty day negotiating window, even as they continue to spar publicly over what exactly they agreed to sign.
