The Nobel Peace prize is being announced in Oslo today. Widely tipped to receive the top award is former Finnish president Martti Ahtisaari for his role in securing a peace accord in Indonesia’s Aceh province which ended three decades of conflict. Ahtisaari, who is renowned for his peace work around the world, is currently the UN special envoy for the future of Kosovo. Another possible candidate is the former foreign minister of Australia Gareth Evans. He heads a Brussels-based think-tank which conducts research and works to prevent conflict around the world. Evans was one of the architects of a peace accord in Cambodia. Last year’s prize went to the International Atomic Energy Agency and its Egyptian chief Mohamed El Baradei.
