FACTBOX - Nobel peace prize winner Martti Ahtisaari

(Reuters) - Martti Ahtisaari, the 71-year-old former Finnish president, won the Nobel Peace Prize on Friday for his work in peace negotiating.

Here are some key facts on Ahtisaari:

* THE AWARD:

-- The prize committee said that Ahtisaari won this year's prize for his efforts on several continents and over more than three decades to resolve international conflicts. These efforts have contributed to a more peaceful world and to "fraternity between nations" in Alfred Nobel's spirit.

-- In early October, Ahtisaari also received the UNESCO's Felix Houphouet-Boigny Peace Prize for his lifetime contribution to world peace.

* WHAT HE HAS DONE RECENTLY:

-- Until March last year Ahtisaari mediated Serb-Albanian talks on Kosovo as the EU's envoy.

-- Acting as point man for the European Union, in 1999 Ahtisaari persuaded then Yugoslav President Slobodan Milosevic to accept NATO's terms for ending the Kosovo air campaign. The work earned him a Nobel Peace Prize nomination.

-- He had bowed out of national politics in 2000 to work with international organisations promoting peace and crisis resolution, accepting projects in Northern Ireland, Israel and the Horn of Africa.
