The Islamist rebel groups operating in western Syria have taken quite the hit over the last 24 hours, as several field reports have revealed the heavy losses sustained to their leadership inside the provinces of Aleppo, Damascus, Latakia, and Hama.

According to a military source in the Aleppo Governorate, the Syrian Arab Army (SAA) killed the following Islamist rebel officers in the last 24 hours: Abu ‘Ali Al-Na’imi (Harakat Ahrar Al-Sham), Abu Mu’az Al-Shami (Jabhat Al-Nusra), Saleh Sindah (Jaysh Al-Islam), Uqaba Abu Ahmad (Liwaa ‘Umar Al-Farouq), Abu ‘Abdo Saqr (Jaysh Al-Islam), Abu Ahmad Khalil (Liwaa ‘Umar Al-Farouq), and Ashraf Jami’ah Al-Muhayr (Harakat Ahrar Al-Sham).

In addition to the heavy losses to their leadership, the Islamist rebel groups have also sustained significant losses to their military personnel, as social media activists from Islamist factions like “Jaysh Al-Islam” (Army of Islam) revealed images of their fighters mourning the death of 80 of their recently killed members.

Overall, in the month of October, Al-Masdar News was able to account for 56 field commanders from the Islamist rebel groups and the Islamic State of Iraq and Al-Sham (ISIS) that have been reportedly killed by the Syrian Arab Army and/or the National Defense Forces (NDF).

While none of these field commanders hold a very high ranking title in their organizations, they were still militants that led military operations against the Syrian Arab Army and their allies inside the country.
