TEHRAN, Aug 20 (SPA) - Iran said on Sunday it would not suspend uranium enrichment, ruling out the main demand in a package of proposals backed by six nations aimed at resolving its nuclear standoff with the West. Iran has so far shown no sign it will accept the offer made in June by the United States, Russia, China, France, Britain and Germany, but Tehran has said it would give its formal response by Tuesday, Aug. 22. "We are not going to suspend (enrichment). The issue was that everything should come out of negotiations, but suspension of uranium enrichment is not on our agenda," Foreign Ministry spokesman Hamid Reza Asefi told a weekly news conference. "As the proposal has had several dimensions, our answer will be multi-dimensional too," Asefi was quoted as saying by Reuters.--SPA www.spa.gov.sa/383894
