Iran strengthens storage and defense of highly enriched uranium stockpile, lays landmines and causes tunnel collapse

According to CNN, five sources familiar with US intelligence have revealed that Iran has recently strengthened its efforts to stockpile highly enriched uranium, including causing tunnels to collapse and laying landmines at the entrance. A month ago, US President Trump publicly hinted that he may order the US military to seize the batch of nuclear materials. Currently, the removal of Iran's highly enriched uranium stockpile requires heavy excavation equipment and mine clearance work.
