ISW is issuing a correction to the map published on July 10,
2017. The three corrections are circled as changes on this version. ISW removed
ISIS’s control zone in eastern Qalamoun, northeast of Damascus. ISIS retreated
from this zone on 25 MAY 2017. ISW expanded ISIS’s control zone east of Tel
Afar, west of Mosul. ISIS held this terrain from 2014 onward, which ISW had
under-represented historically. ISW refined an estimate for ISIS’s support
zones in Idlib province. ISIS re-infiltrated Idlib province in 2015, in
conjunction with its loss of critical border crossings in Aleppo and Raqqa
provinces. Hayat Tahrir al-Sham and other al-Qaeda linked groups are presently
attempting to disrupt ISIS’s operations in Idlib.
