apparently an F16 was hit (but not downed) over Gaza, which points to a MANPAD that has lighter warhead as a bigger medium-range missile would >90% take it down in that case, but airlines don't want to risk especially after this in Ukraine.
I don't know where Hamas could even find medium-range SAM but Assad, as much as he doesn't like Hamas, would like to take down several israeli planes so he could have proliferated them a SAM or two, nothing is impossible today.
