WASHINGTON --
Secretary of State Hillary Rodham Clinton says the U.S. is preparing new penalties against Iranians following the disruption of an alleged plot to assassinate a Saudi diplomat in the U.S.
In an interview with The Associated Press, Clinton said the Treasury Department soon would put more people under sanctions. She also predicted the plot would further isolate Iran.
Attorney General Eric Holder and FBI Director Robert Mueller said the plot to kill the Saudi ambassador was conceived by agents of the Iranian government.
