The forces of al-Assad's regime are withdrawing also from Hama now and "very likely in the next few hours the city Hama will be under the control of Tahrir al-Sham [rebranded regional al-Qaeda] which is affiliated with Turkey's government", according to Aryen TV.
The SDF (YPG, YPJ, etc) reportedly decided to leave Aleppo's airport because they needed to prioritize protecting the many civilians in the neighborhoods defended by them, both previous residents and newcomers.
A view of Aleppo this evening showing smoke rising from the airstrikes. I've only heard of Russia doing airstrikes there now, so presumably all theirs.
I have seen several mass-fatalities out of which some appear to have been civilians, but most appeared to be groups of Turkey's "jihadist" auxiliaries or the rebranded regional al-Qaeda. At least two of that grouping also appear to have tried to attack Şêx Maqsud but were seemingly fatally shot during combat by defenders which seemed to be YPG together with local residents.
