DUBAI: Lebanon expects a written offer from US mediator Amos Hochstein concerning the demarcation of a maritime border with Israel by the end of the week, Lebanon’s presidency tweeted on Monday. Lebanon’s deputy speaker of parliament Elias Bou Saab met with Hochstein last week during a visit to New York and briefed President Michel Aoun on the outcome, the presidency added. Hochstein has been shuttling between Lebanon and Israel — enemy states with a history of conflict — in a bid to forge a compromise over the maritime boundary that would allow both to explore for offshore energy reserves. A deal would defuse one potential source of conflict between Israel and the heavily armed, Iran-backed Lebanese group Hezbollah, which has warned against any Israeli exploration and extraction in the disputed waters.
