The United States and key European countries failed to make any progress with Russia on the scope of UN sanctions that Iran should face for refusing to rein in its nuclear program and suspend uranium enrichment. US Ambassador John Bolton said Wednesday there were still "wide gaps" between the Russians and Europeans, a view echoed by Russian Ambassador Vitaly Churkin. The five veto-wielding Security Council members - the US, Russia, China, Britain and France - and Germany have now held six rounds of closed-door talks here with both camps refusing to budge. "We'll report back again that after the sixth meeting, we are still basically where we have been," Bolton said. Asked whether there had been any progress since the talks began, he said, "Well, we didn't make any progress today - let's leave it at that."
