Iran's moves to speed up nuclear programme troubles West

Iran has begun installing advanced centrifuges at its main uranium enrichment plant, the UN nuclear watchdog said on Thursday, a defiant step that will worry Western powers ahead of a resumption of talks with Tehran next week.
In a confidential report, the International Atomic Energy Agency (IAEA) said 180 so-called IR-2m centrifuges and empty centrifuge casings had been put in place at the facility near the town of Natanz in central Iran. They were not yet operating.
If launched successfully, such machines could enable Iran to
speed up significantly its accumulation of material that the West fears could be used to devise a nuclear weapon. Iran says it is refining uranium only for peaceful energy purposes.
Iran’s installation of new-generation centrifuges would be “yet another provocative step,” US State Department spokeswoman Victoria Nuland said in Washington.
White House spokesman Jay Carney warned Iran that it would face further pressure and isolation if it failed to address international concerns about its nuclear programme in the Feb. 26 talks with world powers in the Kazakh city of Almaty.
