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

The president had not been mentioned as among front-runners for the prize, and the roomful of reporters gasped when Thorbjorn Jagland, chairman of the Nobel committee, uttered Obama's name.

The president, who was awakened to be told he had won, said he was humbled to be selected, according to an administration official.

The Nobel committee recognized Obama's efforts to solve complex global problems including working toward a world free of nuclear weapons.
