Iran seals uranium cache, plants explosives amid fears of US operation

Iran has sealed a cache of near-bomb-grade uranium by collapsing tunnels and placing explosive mines at entrances amid fears that the US was planning to seize the material as part of an operation. The move is seen as a last-ditch effort to protect its nuclear program from potential intervention by foreign powers. Iranian authorities have been working to conceal the site, which is believed to contain highly enriched uranium, in recent days. The situation raises concerns about the stability and security of Iran's nuclear facilities.
