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.
