Ahrar Al-Sham

Ahrar al-Sham Harakat Ahrar ash-Sham al-Islamiyya (Arabic: حركة أحرار الشام الإسلامية ‎ Ahrār ash-Shām, meaning "Islamic Movement of the Free Men of the Levant") A coalition of Islamist brigades that "cooperates with the Free Syrian Army and other secular rebel groups; however, it does not maintain ties with the Syrian National Council," and have "their own strict and secretive leadership, receiving the majority of their funding and support from donors in Kuwait." Ahrar al-Sham was a founding and leading member of the Syrian Islamic Front, and was a member of the Turkish-sponsored 2015 Idlib "army of conquest" along with Al-Nusra.

a hardcore Islamist terrorist group active in northern Syria and endorsed by Robert Ford and other war criminals.

One of five core groups clearly implicated by a detailed Human Rights Watch investigation for complicity in the premeditated and blatant masscare of over 200 Alawi civilians in villages of Latakia, on August 4, 2013 - (the others are ISIS, Jabhat al-Nusra, Jaish al-Muhajireen wal-Ansar, and Suqour al-Izz)

Reuters, Oct. 11 reports a sort of denial from the group: "If someone uses a weapon against you, you have to fight them. If they do not, you must not kill them," and that's it. The unstated half could be that the Alawites raised the sword against them (all Sunnis) so the Alawites have to die. That vague statement was from "Ahrar al-Sham's political office in Raqqa." Raqqa was taken over by Islamists in March, 2013, and then taken by Daesh (ISIS) as their capitol in mid-August, just as this Latakia offensive was ending. So if Ahrar al-Sham had its offices there two months later, it suggests they were working with the Islamic State at that time (the Wikipedia entry doesn't mention any alliance or breaking of it, as it does with the other two).

HRW found "three Moroccan fighters from Ahrar al-Sham that were killed in Esterbeh on August 4."

HRW reports "In one of the videos, lieutenant colonel Hussein al-Harmoush, the brigade commander from Harakat Ahrar al-Sham al-Maghdad al-Aswad battalion, is identified by name and seen shooting in the operation." That's either a nickname taken in honor of an FSA Godfather, the late Lt. Col. Hussein Harmoush (external profile) or quite a coincidence.
