Clinton: Plot a dangerous escalation by Iran

Secretary of State Hillary Rodham Clinton is calling an alleged Iranian plot to kill Saudi Arabia's ambassador to the United States a "dangerous escalation" in Iran's support for terrorism that must draw an international response.

Speaking to a conference in Washington on Wednesday, Clinton said the plot was a "reckless act" that "undermines international norms and the international system" and that Iran must be held accountable for its actions. (AP)
