FBI, DEA thwart terror plot in U.S. involving Iran, officials say
Attorney General Eric Holder, when asked how Iran would be held "accountable" in an alleged plot to assassinate the Saudi ambassador to the United States, said he expected action from the White House, the State Department and Treasury within the next few hours.
A US official expanded more about how the U.S. might hold Iran accountable. The official told CNN's Elise Labott that there are likely to be more sanctions and the U.S. will be taking this up with to the United Nations Security Council and other members of the international community.
