President Barack Obama won the 2009 Nobel Peace Prize on Friday in a stunning decision designed to build momentum behind his initiatives to reduce nuclear arms, ease tensions with the Muslim world and stress diplomacy and cooperation rather than unilateralism.

Obama said he was surprised and deeply humbled by the honor, and planned to travel to Oslo to accept the prize, which he said he does not see "as a recognition of my own accomplishments," but rather as a recognition of goals he has set for the United States and the world.

"I do not feel that I deserve to be in the company of so many transformative figures that have been honored by this prize," Obama said.
