Iran's President Orders Higher Enrichment of Uranium Iran's President Mahmoud Ahmadinejad has ordered the production of higher-enriched uranium, casting doubt prospects of a nuclear exchange deal with the West. 07 February 2010 Iran Nuclear Iran Nuclear Iran's president has ordered his country's atomic agency to begin producing higher-enriched uranium, a move that casts doubt on the prospects of a nuclear exchange deal with the West. In comments broadcast Sunday on state-run television, Mahmoud Ahmadinejad said he has asked the head of the atomic energy agency Ali Akbar Salehi to begin enriching uranium to 20 percent. The uranium would be used to fuel a research reactor. A day earlier, U.S. Secretary of Defense Robert Gates said he sees no indication that a nuclear deal is close between Iran and a group of world powers, despite claims by Tehran. Under the U.N.-backed proposal, Iran would send its low-enriched uranium abroad in return for higher-grade nuclear fuel. The United States and other nations believe Iran is seeking to build a nuclear weapon, while Iran insists its nuclear program is for peaceful purposes only. During Sunday's speech, President Ahmadinejad also said Iran has the capability to enrich uranium using laser technology. He also blamed world powers for the stalemate over the fuel deal, but said Iran is still open to possible negotiation over the proposal. On Tuesday, the Iranian leader said his government was willing to send uranium abroad for further enrichment. And Iranian Foreign Minister Manouchehr Mottaki told an international security conference that Iran was nearing agreement with world powers on a nuclear fuel exchange. The major players involved in the discussion over Iran's nuclear program are the five members of the U.N. Security Council -- the United States, China, Russia, France and Britain -- plus Germany, a group known as the P5 plus 1. Some information for this report provided by AP, AFP and Reuters. .
