While TRUMP purportedly “obliterated” Iran’s infamous Fordow facility, concerns linger that the nuclear program persists within another clandestine mountain stronghold.

Iranian officials have claimed the key enriched uranium was carted out of Fordow before the bombs fell – and Pickaxe Mountain could be its new home.

Pickaxe is a summit within the mountainous region encircling Natanz, which is another one of Iran’s nuclear sites targeted by the US and Israel, located about 90 miles south of Fordow.

The site is still under construction, but has been secretly expanded and reinforced over the past four years.

The peak is over 5,000ft high – taller than any mountain in the UK – and the site is thought to be buried 328ft down.

The chief of the UN’s nuclear watchdog remarked last year: “It is evident that significant and numerous activities connected to the program are occurring in this location.”

When asked what was going on beneath Pickaxe, Iran responded: “It’s none of your business.”

Satellite images show tunnels feeding into the mountain and leading to a deep-buried operation.

Experts say it could be more secure than any of the facilities struck by the US and Israel.

America’s bunker-buster bombs were the only weapons capable of reaching Fordow – but even those might prove ineffective against Pickaxe.

In the days before Trump’s stealth bombing raid over the weekend, a train of lorries was pictured lining up outside Fordow.

And in the aftermath, Iran has claimed that it moved the key nuclear material.

It’s believed there was 400kg of uranium enriched to 60 percent at the plant which, if still intact, could sustain Iran’s ambitions to build nuclear weapons.

Sima Shine, with decades of experience in the military establishment, said Tehran had “hundreds if not thousands” of advanced centrifuges capable of producing weapons-grade uranium.

And Pickaxe could be the perfect new hiding spot.

Rafael Grossi, head of the International Atomic Energy Agency (IAEA), said it cannot be ruled out that there is further, undeclared material hidden beneath the towers of rock.

Grossi renewed his demands that Iran let inspectors in to “account for” the stockpiles of uranium.

Trump claimed that other Iranian sites had been “obliterated” by the US airstrikes over the weekend.

An Iranian official insisted that “contrary to the claims of the lying US president, the Fordow nuclear facility has not been seriously damaged, and most of what was damaged was only on the ground, which can be restored”.

And the extent of the damage is debated after an intelligence report was leaked on Tuesday night.

The assessment claims that Iran’s nuclear programme was set back by just a few months by the US bombs.

Sources told CBS that the stash of uranium had not been eliminated.

The White House was furious and slammed the “flat-out wrong” assessment leaked by “a low-level loser in the intelligence community”.

America deployed its heaviest weapons against Fordow – 14-ton GBU-57 Massive Ordnance Penetrators.

The monster explosives burrow 60 metres into the ground before detonating.
