The heavily guarded mysterious Fordow bunker is built into the side of a mountain near the city of Qom, around 60 miles of Tehran. It was first made public in 2009, according to officials

Only the U.S. military has the 30,000-pound bomb capable of reaching the facility and the bomber that can carry it.

Hidden away in a mountainside south of Tehran is an enrichment plant that is vital to Iran’s nuclear ambitions - and Israel’s attempts to dismantle them.
