Key Daesh battlefield losses in September were to Iraqi forces in Al Anbar Governorate, as well as outside Al Hawijah. In Syria the majority of losses were in Ar Raqqa, Hamah and Homs provinces, as the Syrian Democratic Forces and Syrian Arab Coalition made progress in Raqqa city (which was liberated on the 20th October), and pro-regime forces conducted operations in western Deir Ezzor.
The map (above, and below with key) depicts Daesh areas of influence, including its net territorial losses—44,500 to 45,500 square kilometers, or about 79 percent of the territory it had dominated in Iraq and 33,500 to 34,500 square kilometers, or about 76 percent of the territory it dominated in Syria—since August 2014. Daesh probably has a presence and freedom of movement in much of the unpopulated areas depicted on the map, but we cannot determine its level of influence in these areas. Our area figures are subject to change because of the dynamic nature of the conflict.
