Pictures are real, It’s a ex Syrian Arab Army ammunition depot being hit and exploding, a large number of secondary explosions of all the weapons stored there caused such a huge blast. Rockets stored there cooking off and flying in all directions probably caused the civilian casualties, there were multiple videos of rockets flying and impacting far from the initial blast. Ammunition stored at a large depot like that can cook off for hours or even days afterwards.
I did a write up on it here, finding the potential facility struck on Google maps
I’d imagine that would cause the exact opposite reaction. When has this kind of thing ever broken morale? In pretty much every post WW2 conflict, all this kind of bombing does is strengthen hatred for the enemy.
