U.S. army through its joint task command in Jordan has demanded allied rebel groups fighting SAA in Syrian desert to withdraw to Jordan, saying this move will facilitate the achievement of de-escalation zone agreement as their defeat is inevitable.

In an audio message, the U.S. army asked Ahmed Abdo Martyrs Forces and Osoud al Sharqiya to enter the Jordanian territories within 48 hours as regime forces and allied Shia militias make rapid advances in the desert, also known as Badia.

The key rebel groups in Badia said last week that regional and International powers are pressing on them to end the fight and to launch attacks on ISIS instead.
