Daesh Areas of Influence – May 2017 Update
Between March 1st and May 31st, Daesh lost further territory in Iraq, as well as in Syria. The group have now lost 70% of the territory they controlled in Iraq in August 2014, and 51% in Syria, as they are continually defeated on the battlefield.
Key Daesh battlefield losses in the period March 1st – May 31st were to Iraqi forces in the Ninawa Governorate, the majority of which were in Western Mosul, and in the region near the Iraq-Syria border. In Syria, Daesh lost additional territory in Ar Raqqa, the Damascus countryside, Dayr-az-Zawr, Halab and Homs provinces. The majority of these loses were in Ar Raqqa and Dayr az Zawr, as the Syrian Democratic Forces and Syrian Arab Coalition isolated Raqqa city.
The map (above) depicts ISIS areas of influence, including its net territorial losses—39,500 to 40,500 square kilometers, or about 70 percent of the territory it had dominated in Iraq and 22,500 to 23,500 square kilometers, or about 51 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 estimates are subject to change because of the dynamic nature of the conflict.
