Ahtisaari wins Nobel Peace Prize
This year's Nobel Peace Prize has been won by peace negotiator Martti Ahtisaari, the Nobel Foundation has announced in Norway's capital, Oslo.
Finland's ex-president has been a UN mediator on Kosovo, helped end the conflict in Indonesia's Aceh province and aided Namibia's independence.
Mr Ahtisaari told Norwegian broadcaster NRK he was "very pleased and grateful" to receive the award.
The laureate wins a gold medal, diploma and 10m Swedish kronor ($1.4m).
The winners were chosen by a secretive five-member Norwegian awards committee from 197 nominations this year.
The Nobel committee commended Mr Ahtisaari, 71, "for his important efforts, on several continents and over more than three decades, to resolve international conflicts".

"He has also made constructive contributions to the resolution of conflicts in Northern Ireland, in Central Asia and on the Horn of Africa," it said.
The committee's Ole Danbolt Mjoes said: "These efforts have contributed to a more peaceful world and to 'fraternity between nations' in Alfred Nobel's spirit."
Mr Ahtisaari, who served as Finnish president from 1994-2000, told NRK he thought his biggest achievement was in Namibia.
"It was absolutely the most important because it took such a long time," he said.
