"On a tactical level, the liberation of Palmyra and the expected advance on Sukhanah greatly reduced ISIS’ ability to threaten key government supply lines, especially along the M5 highway and the road to Aleppo.
The pro-government forces have also launched an operation to seize the town of Quraytayn which is located south from the Tiyas Crossroads. The Syrian forces have already taken Hazm al-Gharbiyat and been advancing on the western gates. Quraytayn is also an important logistical potion, liberation of which will increase the SAA’s freedom of operation in the province.
In a separate development, the SAA and Hezbollah units have liberated the Air Defence Base at the village of Bala al-Kadim and the nearby Zahir Farm pushing Al-Nusra militants from this area in East Ghouta.
How, the Syrian forces control with fire Haush Jarabo which is the only way for the pocket. This makes very difficult for Jaish al-Islam, Jabhat al-Nusra and the Free Syrian Army to retreat from the pocket. If Haush Jarabo is seized by the pro-government forces, the strategic situation will become hopeless for the militants encircled there." southfront
Watch the South Front briefing.
Interestingly, the Syrian Marine Regiment which had been deployed from north Lattakia to reinforce the attack on Palmyra/Tadmur has returned to north Lattakia and are just to the west of Jisr ash-Shugur. That would indicate that the R+6 command is confident that forces on the Palmyra-Deir az-Zor axis are sufficient and that these mobile forces well supplied with air support will be enough in what will be essentially a pursuit. Some stiff resistance should be expected at places like Sukhna but IMO IS morale is not good and they are likely to keep running if pushed hard. I would expect a linkup with the isolated Deir az-Zor force and then a change of the axes of advance to a northern direction and Raqqa. The now functioning airfield at Palmyra will be a big logistical help in keeping all this moving. The return of the Syrian Marines to the north probably presages a renewal of the advance to capture Jisr ash-Shugur.
The pocket in east Ghouta is nearly closed and this will form a death trap for a lot of rebels.
All of this is rapidly weakening IS and the other rebel forces and a general collapse is coming, even in Iraq. pl
