Iran has reportedly taken extraordinary measures to secure its stockpile of highly enriched uranium, according to a CNN report citing sources familiar with U.S. intelligence. The report claims Tehran collapsed tunnels leading to key nuclear material and placed explosive mines around access points to prevent potential seizure attempts. Most of the uranium is believed to be stored deep underground at the Isfahan nuclear complex. The developments come as President Donald Trump pushes for an agreement that could see Iran surrender and remove its enriched uranium stockpile as part of a broader diplomatic settlement.
