The United States has joined European Union leaders in warning Iran that it faces consequences if the country fails to prove its nuclear program is peaceful.
White House spokesman Robert Gibbs issued a statement Friday saying the U.S. remains committed to finding a diplomatic solution to the standoff. But Gibbs says if Iran continues to fail to bring its nuclear program into full United Nations compliance, there will be "credible" consequences.
The statement echoes that of EU leaders earlier Friday who called for additional actions to be taken against Iran for its refusal to halt nuclear activities and its "apparent lack of interest in pursuing negotiations" on the issue.
Western countries suspect Iran is trying to build atomic weapons - a charge Tehran denies.In Iraq, U.S. Defense Secretary Robert Gates saidthat he expects "significant" new sanctions to be imposed on Iran, unless it changes course and follows through on agreements made in October.
