Iran starts moving uranium centrifuges to underground bunker in Fordo, near Qom

From Reuters:

Iran has started moving the machines that enrich uranium for nuclear fuel from its main atomic complex in the central city of Natanz to an underground bunker near the holy city of Qom, its top nuclear official was quoted as saying on Monday...

Iran announced in June that it would shift its production of higher-grade uranium to the underground site at Fordow, in defiance of international calls on Tehran to halt uranium enrichment which some countries say is aimed at developing nuclear bombs...

Iran only disclosed the existence of Fordow to the U.N. nuclear watchdog in September 2009 after learning that Western intelligence agencies had detected the mountain site.

Moving sensitive nuclear work to the underground bunker could offer greater protection against any attacks...
