The Syrian army is on the way to liberate the ISIS besieged city of some 100,000 and garrison of Deir Ezzor in the east of the country. The U.S. has trained a few thousand "New Syrian Army" insurgents in Jordan and is reportedly prepared to march these and its own forces from Jordan through the east-Syrian desert all the way up to Raqqa and Deir Ezzor. About a year ago it occupied the al-Tanf (al-Tanaf) border station which consists of only a few buildings in the mid of the desert. The station between Syria and Iraq near the Jordan border triangle was previously held by a small ISIS group.
A U.S. move from the south up towards the Euphrates would cut off the Syrian government from the whole south-east of the country and from its people in Deir Ezzor. While that area is sparsely populated it also has medium size oil and gas fields and is the land connection to the Syrian allies in Iraq.
With the western part of the country relatively quiet, the Syrian government and its allies decided to finally retake the south-eastern provinces from ISIS. They want to lift the ISIS siege on Deir Ezzor and close the border between Syria and Iraq with its own forces. The move will also block any potential U.S. invasion from the south by retaking the road to al-Tanf and the Syrian-Iraqi border (red arrows). The sovereign Syrian state will not give up half of the country to an illegal occupation by ISIS or the U.S. At the same time as the eastern operations are running consolidation and clearing operations against ISIS in the middle and west of the countries will take place (green arrows).
Yesterday a small battalion size force (~2-300 men) of the regular Syrian army, Syrian National Defense Organization volunteers and Iraqi Popular Mobilization Forces (PMF/PMU of the Kata'ib al-Imam Ali) marched on the road from the west towards al-Tanf.
