The head of the UN nuclear watchdog has reported observed construction at Iran’s Pickaxe Mountain. Western intelligence suggests a subterranean site in Natanz is likely being used for the storage of nuclear material. Former US President Donald Trump also acknowledged “a little activity” at Pickaxe, issuing a warning to Tehran against further actions. This development raises concerns about Iran’s nuclear program and potential violations of international agreements. The specific nature of the construction at Pickaxe Mountain remains unclear, but the reports are prompting scrutiny from international observers. The situation is delicate, with both the UN and former US leadership closely monitoring activities in Natanz. Further investigation is needed to determine the purpose and scope of the observed construction.
