Israel Accuses Iran of Hiding Nuclear Equipment in Tunnels
Israel says Iran has moved equipment used to enrich uranium into secret tunnels under a mountain.
This worries Israel and the US because they think Iran might be trying to make nuclear weapons without anyone knowing.
Iran says it's not making weapons, but it won't let inspectors check the tunnels.
The US president has threatened to attack the tunnels.
The tunnels are very deep and hard to destroy.
Israel and the US are worried Iran might be secretly trying to make weapons-grade uranium.
Israel claims Iran moved uranium-enrichment centrifuges to secret tunnels under Pickaxe Mountain.
The transfer happened after Israeli strikes and a US military operation damaged Iran's nuclear facilities in June 2025.
Iran has not allowed inspections of the site, raising concerns about potential secret nuclear activities.
US President Donald Trump has threatened to target Pickaxe Mountain in the ongoing conflict.
The tunnels are over 100 meters deep and could house several nuclear-related facilities.
