By: Chris Kozak – 22 Jan 2015 – ISW – The Islamic State of Iraq and al-Sham (ISIS) has begun to expand its presence in the Syrian central corridor which stretches from the Jordanian border through Damascus to the central cities of Homs and Hama. The “central corridor” is highly-contested key terrain for both the Syrian regime and its armed opposition, while ISIS presence has generally been limited in the area until recently.
As one major exception, ISIS maintained a notable foothold in several opposition-held areas of Damascus in early 2014 before retreating due to pressure from local rebel groups. A small ISIS contingent, largely overlooked, endured quietly in the southern suburbs of Damascus throughout late 2014. Over the past two months, ISIS has once again escalated its military and public relations activities in this area, threatening to divert both regime and rebel resources away from active fronts in the Damascus area in order to contend with the ISIS threat. This development may provide an indicator of ISIS’s broader expansion plans in western Syria and the potential response of Syrian opposition fighters to this expansion.
