And it’ll cause more injuries than deaths.
That is the entire problem with chemical weapons. They injure people badly.
That’s why chemical weapons are banned while bombs aren’t.
That’s actually not the problem with chemical weapons. Chemical weapons are banned due to their indiscriminate nature (being blown by the wind) and really the fact that it causes slow deaths over years. It’s that it’s tantamount to torture (which is also banned).
Blowing people’s limbs off is considered A-OK as long as it’s not done with land mines.
And land mines are only banned because, checks notes, their indiscriminate nature (being walked on by children)
That and they just stay there active, decades after the conflict. There are still minefields from decades old conflicts that kill/injure people today.
