US President Barack Obama has won the 2009 Nobel Peace Prize.

The Nobel Committee said he was awarded it for "his extraordinary efforts to strengthen international diplomacy and co-operation between peoples".

There were a record 205 nominations for this year’s prize.

The laureate - chosen by a five-member committee - wins a gold medal, a diploma and 10m Swedish kronor ($1.4m).

U.S. President Barack Obama won the Nobel Peace Prize on Friday for his calls to reduce the world’s stockpile of nuclear weapons and working for world peace.

The first African American to hold the country’s highest office, Obama has called for disarmament and worked to restart the stalled Middle East peace process since taking office in January.
