In September 2007, United Nations special envoy to the Horn of Africa, Kjell Magne Bondevik, warned that war could resume between Ethiopia and Eritrea over their border conflict. In November, Eritrea accepted the border line demarcated by the international boundary commission, which was rejected by Ethiopia. In January 2008 the UN extended the mandate of peacekeepers on Ethiopia-Eritrea border for six months, and UN Security Council demanded Eritrea lift fuel restrictions imposed on UN peacekeepers at the Eritrea-Ethiopia border area. Eritrea declined, saying troops must leave border, and in February the UN began pulling out the 1,700-strong peacekeeper force due to lack of fuel supplies following Eritrean government restrictions. In April, UN Secretary-General Ban Ki Moon warned of the likelihood of new war between Ethiopia and Eritrea if peacekeeping mission is withdrawn completely, and outlines options for the future of the UN mission in the two countries. In May, Eritrea called on UN to terminate the peacekeeping mission., BBC News, 19 June 2008
