You did write the comment however…

BBC again forgot to mention that Hamas is literally producing weapons in these facilities and thus making them legitimate military targets as by the Geneva conventions. The color of the smoke alone is usually enough to prove that, black smoke means there are weapons or large amounts of fast burning chemicals (resources for weapons like gunpowder or ammonium fertilizer) white smoke means no such things (a miss)

And no, a school doesn’t store large amounts of these chemicals normally, also a evacuation order was given before.
