The above demarcation lines were fixed by the Rhodes Armistice Agreements. Article V.2 of the Agreement with Egypt (in similar terms to the other Agreements), provided:

“The Armistice Demarcation Line is not to be construed in any sense as a political or territorial boundary, and is delineated without prejudice to rights, claims and positions of either Party to the Armistice as regards ultimate settlement of the Palestine question.”
