UPDATE: IAEA chief confirms nuclear inspectors will visit Iranian sites despite Iran's denials, marking critical development in US-Iran deal implementation.
The head of the International Atomic Energy Agency signaled Wednesday that inspectors will visit Iranian nuclear enrichment sites, providing the clearest confirmation yet of a key component in the interim U.S.-Iran deal. IAEA chief Rafael Mariano Grossi told reporters that a Memorandum of Understanding signed by both presidents explicitly states nuclear activities will be supervised by the agency, and that inspections "are going to happen" whether in days or weeks.
The confirmation comes after days of contradictory statements from U.S. and Iranian officials. On Tuesday, Iran's Foreign Ministry spokesperson said UN inspectors were not scheduled to examine nuclear sites bombed by the U.S. last year, directly contradicting Vice President JD Vance's claims that discussions with inspectors could begin immediately. President Trump insisted Iran had "fully and completely agreed" to inspections, warning that without such agreement, negotiations would end.
The inspections are critical for verifying Iran's uranium stockpile, which is believed to contain enough highly enriched material to potentially build up to 10 nuclear weapons if Iran chose to pursue them. Since Israel's 12-day war on Iran in 2025, the IAEA has been blocked from visiting enrichment sites. Iran is the only country in the world to have uranium enriched up to 60% purity without an acknowledged weapons program. The interim deal calls for Iran to dilute its stockpile from highly enriched levels, with both sides given 60 days to hammer out broader agreements.
Editor’s rationale — High institutional impact from major US-Iran nuclear negotiations with potential structural changes to sanctions regime and international inspections; nationwide and global economic implications through oil markets and Strait of Hormuz access; durable long-term relevance given 60-day timeline toward final deal; primary sources (Trump, Vance, Iranian officials) but conflicting claims undermine certainty on core commitment details.
