A group of Syrian rebels and refugees began to leave a border enclave in Lebanon for Syrian territory on Monday (August 14) under a deal worked out with Lebanese and Syrian authorities.

The departure of rebels, from a group called Saraya Ahl al-Sham, will leave an Islamic State enclave as the last militant stronghold straddling the border near the Lebanese town of Arsal, which is home to tens of thousands of refugees.

About 300 rebels from the group as well as about 3,000 refugees left Lebanon under the deal that followed an assault by the Lebanese Shi’ite group Hezbollah on insurgent positions last month.

The transfer involving the rebels and another one early this month of Nusra Front fighters and refugees, are similar to deals struck within Syria in which Damascus has shuttled rebels and civilians to opposition areas.

The Lebanese army is expected soon to assault the Islamic State pocket in the same area.
