As the United States and Iran move closer to what could become a significant peace agreement, fresh intelligence reports suggest that Tehran has taken extensive measures to secure and conceal its stockpile of highly enriched uranium. According to a CNN report citing multiple sources familiar with US intelligence assessments, Iranian authorities have strengthened protection around key nuclear sites by collapsing access tunnels and placing explosive mines near entry points, making access to the material substantially more difficult.
The reported actions come only weeks after US President Donald Trump publicly discussed the possibility of using military means to secure Iran's enriched uranium reserves. Intelligence officials believe the fortifications have significantly increased the complexity of any future effort to recover, inspect, or remove the material. The uranium stockpile is estimated to amount to roughly half a ton of highly enriched uranium, making it one of the most sensitive issues in ongoing negotiations between Washington and Tehran.
The development has introduced an additional challenge to the proposed framework, reportedly under discussion between the two countries. Under the plan, Iran would surrender its stockpile of enriched uranium to the United States, after which the material would be destroyed and removed from Iranian territory. While American officials have indicated that negotiations are progressing and that both sides are moving closer to an agreement, differing public statements from Washington and Tehran continue to create uncertainty regarding the final terms.
Nuclear experts have warned that the new fortifications could make any verification or recovery effort far more complicated than originally anticipated. Extensive excavation work, tunnel clearance operations, and de-mining procedures may be required before inspectors or technical teams can safely reach the stored uranium. Such operations could take considerable time and resources,s even if a formal agreement is signed.
According to the report, some US intelligence officials believe Tehran's decision to further fortify the sites may have been influenced by Trump's public comments regarding the possibility of targeting the uranium stockpile. The concern among experts is that the physical inaccessibility of the material could create future disputes over verification and compliance, even if both sides reach a diplomatic settlement.
Scott Roecker, a former senior official responsible for nuclear material removal at the US National Nuclear Security Administration, said the situation could create significant verification challenges. He explained that if Iran is required to move all of its enriched uranium to a central location for inspection and eventual disposal, the responsibility for retrieving and declaring the entire inventory would rest with Tehran. However, he cautioned that Iran could later argue that portions of the stockpile remain inaccessible due to collapsed tunnels or other obstacles.
Such a scenario could complicate international efforts to independently verify whether all highly enriched uranium has been accounted for. Experts warn that any uncertainty regarding the completeness of Iran's declarations could leave lingering concerns that some material might remain hidden or accessible in the future, potentially undermining confidence in the agreement.
Most of the uranium is believed to be stored within collapsed tunnel networks at the Isfahan nuclear complex in central Iran, while additional quantities are reportedly held at other locations. According to the CNN report, US military planners had examined the possibility of an operation to seize the material earlier this year but ultimately concluded that the risks involved were too high. Since then, Iran has reportedly continued strengthening protective measures around the sites.
The issue comes at a critical moment in the diplomatic process. Earlier on Saturday, Pakistan's Prime Minister Shehbaz Sharif stated that the United States and Iran had agreed on a framework for a peace deal and were preparing for an electronic signing within twenty-four hours, followed by technical-level negotiations. Iranian officials, however, rejected claims that a final agreement had already been reached, saying discussions were still ongoing and that a conclusion could take several more days.
While negotiators appear to be making progress toward a broader settlement, the question of Iran's highly enriched uranium stockpile remains one of the most technically challenging and politically sensitive issues on the table. Even if a peace agreement is ultimately finalised, the practical task of locating, verifying, securing, ng and removing the material may prove to be a lengthy and complex process that extends well beyond the signing of any diplomatic accord.
