Speaking purely as SLF, surely not entering Damascus FIR is the only option?
Scuds are being fired, there is significant air activity involving Migs that are bombed up. They, and choppers, are occasionally being shot down by SAMs. There is shaky mobile footage of a landing plane at Damascus (I think) sustaining what seems to be an RPG hit.
I would have thought that anyone with any sense would stay well clear!
