The Group of Eight called on Iran Friday to immediately halt post-election violence but refrained from calling into question the legitimacy of President Mahmoud Ahmedinejad's re-election. The leading powers were divided over how to respond to the crisis in Iran with Russia warning against isolating Tehran with a toughly-worded condemnation that risked derailing talks on its nuclear drive. In a compromise declaration, G8 foreign ministers backed off from harsh criticism and called for the crisis to be settled "soon" through peaceful means. "We want violence to stop immediately," Italian Foreign Minister Franco Frattini told a news conference after releasing the declaration from the G8: Britain, Canada, France, Germany, Italy, Japan, Russia and the United States.
