Iran Installs 6,000 New Centrifuges

TEHRAN, Iran -- Iran has begun installing 6,000 new centrifuges at its uranium enrichment plant in Natanz, President Mahmoud Ahmadinejad said Tuesday, a move Western nations condemned as defiance of United Nations demands for Iran to halt enrichment.

French Foreign Minister Bernard Kouchner called the move "dangerous" and said UN sanctions against Iran should be increased.

"If that continues we must reinforce sanctions, but we also must continue dialogue," Kouchner said. "I fear that we will have to continue ... toward sanctions if we do not encounter responses from the Iranians."

Iran already has about 3,000 centrifuges operating at its underground nuclear facility in Natanz, and the UN has passed three sets of sanctions against Iran for its refusal to suspend uranium enrichment. Tehran insists its nuclear program is focused on the peaceful production of energy, not the development of weapons as claimed by the United
