Military sources said, on Saturday , that the Syrian troops – backed by allied forces – have managed to drive out the US-backed rebels from 9 new bordering outposts , 177 till 185 , in the far eastern Damascus countryside.
The advance comes as part of a wider push waged by the Syrian government forces to secure the stretching desert land along the borders with Jordan.
The recently-recaptured bordering outposts are located to the south of al-Tanf, where the US-led coalition have set up a garrison to train its proxies in Syria .
