The Israel Defense Forces say they delivered a decisive blow to Iran by destroying a covert nuclear-weapons development site this week.
IDF Chief Spokesman Brig.-Gen. Effie Defrin publicly identified the facility as Min Zadai on the northeastern outskirts of Tehran.
Israeli intelligence tracked nuclear scientists who were attempting to travel clandestinely to that location, the IDF said.
By monitoring those movements, the IDF says it uncovered dangerous activity that could have allowed Tehran to revive key components needed for a nuclear bomb.
Israeli officials stressed that uranium enrichment alone does not produce a deliverable weapon without the development of additional weapons components.

The announcement underscores Israel’s long-standing position that Iran’s nuclear program extends beyond civilian energy claims and into weapons research.
The IDF added that since the start of the current war, the Israeli Air Force has destroyed roughly 300 Iranian missile launchers, significantly degrading Tehran’s ability to retaliate.
The latest strike follows Israel’s sweeping bombing campaign in June 2025 when dozens of Iranian sites connected to weapons development were destroyed.
That offensive, launched during the 12 Day War, was widely seen as crippling the weapons-design side of Iran’s nuclear program.
Defrin’s remarks represent the first time the IDF has publicly addressed what it says are Iranian efforts to rebuild portions of that weapons infrastructure since the June conflict.
