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.
