At the present time, ISIS terrorists remain in six areas of Syria.
ISIS militants are in following districts: The Yarmouk Basin (Daraa province); Northwestern Syria (in Idlib, Aleppo and Hama provinces); Southern Damascus; Western Deir Ezzor, east Homs desert; Eastern bank of the middle Euphrates valley region; Eastern Deir Ezzor desert near the Iraqi border.
According to the estimates, a number of ISIS members throughout Syria is as follows: The Yarmouk Basin – from 1,500 to 2,000. Northwestern Syria – at least 1,000. Southern Damascus – from 1,500 to 2,000 (some sources claim as high as 3,000). Western Deir Ezzor, east Homs desert – 200. Eastern bank of the middle Euphrates valley region – from 3,000 to 4,000. Eastern Deir Ezzor desert near the Iraqi border – 1,000.
By this range of estimates it becomes apparent that anywhere between 7,700 and 11,200 ISIS terrorists and their affiliated militants remain to operate in Syria.
