Iran Blocks IAEA Access to Bombed Nuclear Sites as Fighting Resumes

Iran’s parliament speaker has told UN nuclear inspectors they will not gain access to the enrichment facilities struck by the United States and Israel — a direct challenge to a core pillar of the June memorandum of understanding that briefly halted the war, and a problem that has grown more acute as the ceasefire collapsed and airstrikes resumed for a seventh consecutive night on Friday.

“Under this law, no access whatsoever will be granted to sites that have been bombed and damaged,” Parliament Speaker Mohammad Bagher Qalibaf said in early July. He specified that IAEA inspectors remain entitled only to the Bushehr Nuclear Power Plant and the Tehran Research Reactor — neither of which is a primary enrichment facility.

The International Atomic Energy Agency is pressing back. Director-General Rafael Grossi has given what Euronews described as his clearest public signal yet that inspections will happen, calling for a “very strong system of verification” and full access to Iran’s enrichment infrastructure — which he described as the key objective of the preliminary ceasefire framework. “Those inspections are going to happen,” Grossi said in late June.

What is at stake

The IAEA has reported a significant deterioration in its situational awareness following US and Israeli strikes that began February 28. The agency told the UN Security Council it has lost continuity of knowledge across all of Iran’s declared nuclear facilities. Iran’s stockpile — assessed as enough highly enriched uranium to produce around 10 nuclear explosive devices — is believed to be largely buried under the rubble of the three main enrichment sites that were bombed.

The practical problem is that nobody outside Iran can currently verify whether that material was destroyed in the strikes, moved before them, or remains intact in some portion. An analysis by the Institute for Science and International Security of the IAEA’s June safeguards report found that Iran is formally in breach of its safeguards agreement.

The MOU dispute

The June memorandum of understanding committed the United States and Iran to “negotiating and achieving” a deal — covering Iran’s nuclear program and US and UN sanctions — within a maximum of 60 days, with the final agreement to be endorsed by a binding UN Security Council resolution. Washington has insisted that nuclear inspections were “fully agreed on” in the MOU and subsequent talks. Tehran has countered that discussions on the topic remain “limited for now,” according to CNBC’s reporting on the deal terms.

That gap was a source of friction even before the ceasefire formally collapsed. When US strikes resumed — entering a seventh consecutive night as of Friday, now targeting bridges and civilian port infrastructure in southern Iran and drawing fresh IRGC counter-strikes against US bases across six Gulf states — the inspection standoff lost diplomatic momentum but gained strategic urgency.

Any future ceasefire will require resolving the verification question as a precondition for sanctions relief. A deal that does not include verified access to the bombed sites would leave the United States unable to confirm whether Iran’s weapons-usable material was destroyed or relocated — exactly the ambiguity that makes a nuclear agreement unenforceable.

Iran’s legal position

Tehran’s legal framing rests on domestic legislation that conditions cooperation with the IAEA on reciprocal steps by Western governments. Qalibaf invoked that statute directly. Iranian officials have separately argued that granting access to bombed sites would expose sensitive military and intelligence information to an agency whose member states include the United States and Israel.

Grossi acknowledged the legal and political complications but declined to set a deadline, saying only that the inspections would happen “as part of the deal” — a deal that does not currently exist.

What comes next

The IAEA’s ability to verify Iran’s nuclear status depends on physical access to sites Iran’s legislature has formally placed off limits. As the Strait of Hormuz shipping crisis deepens and both sides absorb another exchange of strikes and counter-strikes, the nuclear file has moved from the front of the diplomatic agenda to its foundation — the question that will determine whether any eventual agreement carries real weight.

Three markers worth watching:

1. Whether Grossi sets a specific deadline for access or escalates to a formal Board of Governors referral, which would trigger additional UN Security Council consideration.
2. Whether a US-Iran back channel produces a framework for phased inspection access as a confidence-building measure ahead of a full deal.
3. Whether commercial satellite imagery gives the IAEA or independent analysts an independent read on the physical condition of Iran’s bombed enrichment infrastructure — and whether that shapes the negotiating position of either side.
