The Blue Line is a border demarcation between Lebanon and Israel published by the United Nations on 7 June 2000 for the purposes of determining whether Israel had fully withdrawn from Lebanon. At the same time, an extension, expressly not to be called the Blue Line nor considered the legally demarcated international boundary according to the UN, identified the Israeli withdrawal line between Lebanon and the Israeli-controlled Golan Heights.
