Russian President Vladimir Putin said on Wednesday that reports of an assassination plot against him in Iran were an attempt to “wreck” his landmark visit here this week.

European governments are deeply divided over imposition of new sanctions against Iran, in what could undermine a new US effort to mobilize allies to act outside of the United Nations, according to European officials.

  U.S. President George W. Bush warned on Wednesday that if Iran develops nuclear weapons, the result could be a new world war.
