Reports are coming out of Iran that a large explosion has destroyed much of Iran’s Fordo nuclear facility. Fordo is thought to be Iran’s second largest nuclear facility and plays a key role in Iran’s nuclear weapons development program. The reports have not been corroborated by any official Western source, yet, but it seems clear that a large explosion did in fact take place at Fordo, which is carved into a mountain and is considered to be impregnable to airstrikes and most bunker buster bombs.
