The US withdrawal from Syria includes the withdrawal from the remote US military base at al-Tanf, and that's got some of the rebel factions in the southeastern area around the base wondering what comes next.

Reporters say that many of the rebels are openly saying that they intend to lay down their arms and surrender as soon as the US leaves al-Tanf, and try to join into one of the Syrian government's reconciliation offer.

On the other hand, commanders from the US-backed Mahavir al-Saura brigade are looking for life after the US by issuing a demand for Syria to grant them safe passage for 6,000 fighters into the rebel-held northern Syria area around Idlib.
