Iran fortifies underground complex near nuclear site, satellite images show

AI Summary

medium article 3 min

Satellite images reveal Iran is fortifying an underground complex near its Natanz nuclear facility at Mount Kolang Gaz La, also known as Pickaxe Mountain. Analyzed by ISIS, the images show strengthened tunnel entrances with fresh concrete and reinforced structures. This activity occurs amidst heightened tensions and ongoing talks between Iranian and US officials, with the US threatening potential military action. Experts speculate the facility could be for protecting uranium enrichment activities or key equipment, but its exact purpose remains unclear. While Iran insists its nuclear program is peaceful, the construction raises concerns about potential sensitive activities, particularly given the facility's size and protective mountain location. The facility is likely not yet operational based on the presence of construction machinery.
