According to reports, Iran has collapsed underground tunnels and laid explosive mines at its nuclear sites to block access to roughly half a ton of highly enriched uranium. The move complicates US-Iran negotiations over removing or destroying the material, as extraction would now require heavy excavation and de-mining.
A new CNN report, citing five U.S. intelligence-linked sources, details that Iran has deliberately collapsed tunnels at facilities storing 60%-enriched uranium and laid mines at site entrances. This dramatic hardening, occurring as of 07:26 Jerusalem when the story broke, physically obstructs access to roughly half a ton of highly enriched material — a development that directly complicates any deal requiring its removal or destruction.
This follows a sequence The Zioneer has tracked since earlier today. At 07:26 Jerusalem, our initial wire noted the Jerusalem Post's confirmation of Iran fortifying its stockpile. By 10:52 Jerusalem, an Israeli assessment reported that most of the 60%-enriched uranium was likely entombed in destroyed tunnels at the Isfahan nuclear site — an assessment that The Zioneer published as an article at 11:14 Jerusalem. The new CNN report, published at 07:26 Jerusalem alongside those earlier versions, describes a broader, deliberate Iranian effort to seal the remaining stockpile across multiple sites.
Attributed context adds urgency. As The Zioneer reported on June 10 at 22:08 Jerusalem, Tehran was internally hesitating over relinquishing its 60%-enriched stockpile. By 07:56 Jerusalem, reports indicated Israeli concern that the emerging U.S.-Iran deal would allow diluted uranium to remain in Iran rather than being removed — a concern Defense Minister Gallant echoed in a pointed English tweet, 'Where's the uranium?', published by The Zioneer on June 12 at 15:30 Jerusalem. The new report aligns with that concern: Iran is physically entrenching its nuclear assets against removal.
What remains unverified is the precise quantity of uranium affected by these measures — roughly half a ton according to the report — and whether all of it is at the 60% enrichment level. The intelligence picture, drawn from a single source report (CNN citing U.S. sources), remains developing; no independent confirmation of the mine-laying or tunnel-collapse claims has emerged.
