Iran said on Sunday it had ended voluntary implementation of a protocol allowing snap U.N. inspections of its nuclear sites and halted its suspension of uranium enrichment, after it was reported to the U.N. Security Council. "Iran has stopped all voluntary measures it had undertaken in the past two-and-a-half to three years," Foreign Minister Manouchehr Mottaki told a news conference. "We have no commitment to the Additional Protocol any more and our activities will continue based on the NPT (nuclear Non-Proliferation Treaty)," he was quoted as saying by Reuters.
