Obama: Nobel Peace Prize is 'call to action'

President Obama said Friday that he was "surprised and deeply humbled" by the decision of the Norwegian Nobel Committee to award him the 2009 Nobel Peace Prize.

The committee said it honored Obama for his "extraordinary efforts to strengthen international diplomacy and cooperation between peoples."

Obama said he viewed the decision less as a recognition of his own accomplishments and more as "a call to action."

President Obama, speaking Friday, said the award was "an affirmation of American leadership."
