The United States could pull out of a landmark nuclear deal with India if New Delhi supports Iran's position at an upcoming meeting at the International Atomic Energy Agency, the US ambassador was quoted as saying Wednesday. Ambassador David Mulford said the impact of India's refusal to vote for a proposal to refer Iran to the UN Security Council would be "devastating" to US Congress members, Press Trust of India reported. Under the nuclear pact, signed in July, Washington is to share civilian nuclear technology and supply nuclear fuel to India in return for New Delhi allowing international inspections of its civilian atomic facilities and other concessions. The IAEA, which will hold an emergency board session on Feb. 2, can refer Iran to the U.N. Security Council for pursuing a nuclear program. European countries believe they have enough votes to haul Iran before the council, but they are seeking support from Russia, China and key developing nations such as India.
