The Turkish, Russian and Iranian governments had agreed on talks in Astana in Kazakhstan between delegations from "moderate" militant groups in Syria and the Syrian government. Ahrar al Sham, which ideologically borders between al-Qaeda and the "moderates", was also invited. It declined to take part in solidarity with the not invited designated terrorist group Jaish Fateh al-Sham (the former Nusra Front aka al-Qaeda in Syria).

Russia had suggested the talks with the intent of separating the "moderate" Takfiris under Turkish control from the designated "terrorist" Takfiris. The talks had no immediate results but still achieved their purpose. Shortly after the talks began al-Qaeda attacked Ahrar al Sham. After some on and off fighting al-Qaeda started yesterday to attack all "moderate" Takfiri groups in Idleb and Aleppo governate.

I was wrong. Ahrar did not fight with al-Qaeda, al-Qaeda did not attack it. As far as one can tell they coordinated their actions for the purpose of eliminating smaller "rebel" groups under the disguise of Takfiri infighting.
