A Wall Street Journal report, citing unnamed US and Israeli officials, says Iran has transferred nuclear centrifuges to a site referred to as Pickaxe Mountain. The officials’ assessment, as described in the report, is that the transfer occurred last autumn. The report links the move to the period after a June 2025 conflict, when a reported 12-day exchange involved US and Israeli strikes on several of Iran’s nuclear facilities. According to the account, Israeli intelligence tracks the relocation and has reached the conclusion that centrifuge-related activity was moved to the new location months after those strikes. The report does not provide additional technical specifics about the number or model of centrifuges involved, or the exact timing down to specific dates. It also does not state whether Iran publicly acknowledged the move. The claims are presented as the views of US and Israeli officials referenced by the Journal, and they relate to ongoing concerns about Iran’s nuclear program and how it may be structured or safeguarded after military actions.
