Al Arabiya, 5 March 2016 - A border crossing with Iraq was seized by Syrian rebel fighters from ISIS militants on Friday.
According to the Britain-based war monitor, the Syrian Observatory for Human Rights, the al-Tanf border crossing has been controlled by ISIS since May last year.
Prior to that, it had been under the control of Syrian government forces and had been the last border crossing with Iraq that was under their control, according to Reuters news agency,
ISIS, which controls a swathe of territory spreading from Iraq into central Syria, still controls the Bukamal Syria-Iraq border crossing near Deir al Zour.
The Observatory said the rebel fighters who took the crossing crossed into Syria from Jordan.
The crossing is a 240 km drive from Palmyra, also known as Tadmur, which has been under ISIS control since the middle of last year.
