The continued presence of United Nations forces in that area would violate the provisions of the Constantinople Convention of 1888 and would constitute a clear infringement of the sovereign rights of Egypt. It goes without saying that the United Nations forces must also withdraw from the demarcation line and from Egyptian territory in general as soon as the Republic of Egypt should consider it necessary.
