US mediator Amos Hochstein is arriving in Beirut on Thursday afternoon, and he is expected to bring answers regarding the entire file. Sources following the situation told "Al-Anbaa" electronic news that "the issue of border demarcation is not as simple as some talk about, and those who bet on signing the demarcation agreement within this month may be surprised by a delay in deciding it until next month for logistical and political reasons. However, the issue has made significant progress toward being approved for implementation based on a mutual desire from Europe and the US, as well as for Lebanon and Israel," according to Al-Anbaa.
