On September 10, the Syrian Arab Army (SAA) and its allies captured 4 new border posts (173, 174, 175, 176) on the Syrian-Jordanian border in the southeastern Damascus countryside according to the Hezbollah media wing in Syria.
Furthermore, the SAA captured Rajm al-Matitah and Qabr al-Khatib near the Jordanian border in the southeastern Damascus countryside.
Meanwhile, Russian warplanes carried out airstrikes on positions of the US-backed Free Syrian Army (FSA) groups of Jaysh Usud al-Sharqiya and Ahmad al-Abdo Forces near the Jordanian border.
The SAA will likely continue its advance along the border until it reaches its final target 50km south of the US-led collation base in al-Tanaf near the Iraqi border.
On September 9, Jaysh Usud al-Sharqiya fighters targeted a position of the SAA on the Syrian-Jordanian border with a Bulgarian-made Fagot Anti-Tank Guided Missile (ATGM).
These missiles were supplied by the US to the FSA groups in Syria. ISIS had used the same type of the missile – distinguished by the white color of the missile container – in the eastern Aleppo countryside.
It’s possible that ISIS has bought some of these missiles from the US-backed FSA groups in al-Tanaf base. On September 1, a defector from the FSA told the Russian “Russia 24” TV channel that FSA groups in al-Tanaf base were indeed selling US-supplied weapons to ISIS.
