According to recent reports, Israeli intelligence says Iran moved thousands of fission devices to a secret underground site in Pickaxe Mountain near Natanz, as reported by sources. This happened in 2025. The centrifuges join others earlier hidden in tunnels across the Alborz mountains. Israel provided these details to The Wall Street Journal. The International Atomic Energy Agency has not made any statement yet. US and Israeli leaders currently weigh potential military steps after Donald Trump said in 2024 that Iran’s nuclear program could press America to act.
