According to Al Jazeera, US President Donald Trump has again threatened to strike Iran's "Pickaxe Mountain" (locally known as Kuh-e Kolang Gaz La), stating that the US still has "one or two (nuclear) sites to deal with" and that the site could be handled "very quickly." The mountain, with an elevation of 1,600 meters, is near Iran's heavily damaged Natanz uranium enrichment facility and contains two deeply buried tunnel complexes. Some Western analysts believe the site may be used to build an undeclared uranium enrichment plant, potentially located too deep for even the most powerful US bunker-buster bombs to reach. The Institute for Science and International Security, after monitoring satellite images, assessed that the facility is still under construction and not yet operational. Trump also praised the ongoing indirect negotiations with Tehran.
