Diplomats from the US, Russia, China, Britain, France and Germany failed on Saturday to settle all their differences over a second UN sanctions resolution against Iran for its failure to halt its nuclear program, Army Radio reported on Saturday night. The failure came after diplomats from the six powerful countries had hammered out language for the new sanctions on Teheran after it refused to suspend its uranium enrichment program. Speaking in Washington on Friday, State Department spokesman Sean McCormack said the United Nations Security Council would likely use the draft language to begin work on a new resolution this week.
