Iran's new uranium bunkers
IRAN has begun uranium enrichment at a new underground site built to withstand possible airstrikes, a leading hard-line newspaper has reported.
The operations at the facility south of Tehran, reported yesterday by the Kayhan daily newspaper, are small in comparison to Iran's main enrichment site.
But the centrifuges at the underground labs are considered more efficient and are shielded from aerial surveillance and protected against airstrikes by up to 300ft of mountain rock.
Uranium enrichment is at the core of the international standoff over Iran's nuclear program. The US and its allies fear Iran could use its enrichment facilities to develop material for warheads.
Iran -- which claims it only seeks nuclear reactors for energy and research -- has sharply increased its threats and military posturing against stronger pressures, including US sanctions targeting Iran's Central Bank.
