that's just the old prime minister kept in place so that whatever underfunded state apparatus was there keeps running, to not worsen humanitarian situation. they don't have anything agreed last time i've checked
It's not though. It's the same guy who has been leading the SSG (HTS's civilian government project) in Idlib. It seems HTS is mostly running the show here, which admittedly doesn't make it clear what the other groups have to say about it.
That's the SNA, which is the other major player in Syria. They're supposed to have been involved in the offensive but I'm not hearing much about them getting involved in Damascus politics.
