TEHRAN, Iran - Iran ended all voluntary cooperation with the U.N. nuclear watchdog on Sunday but said it was open to a proposal to enrich Iranian uranium in Russia, reversing its earlier response to being reported to the Security Council over fears it wants to produce nuclear arms. Foreign Minister Manouchehr Mottaki said Iran had implemented the president's orders to resume uranium enrichment and bar snap inspections by the International Atomic Energy Agency of its nuclear facilities — voluntary measures it allowed in recent years in a gesture to build trust.
