We literally have videos of these going off in public spaces. The explosions were weak enough that people literally inches away were unharmed. The only way to be seriously injured is to be holding it in your hands or against your body.

You cannot seriously call it an attack "on civilians" - you especially cannot say that it's in pursuit of a non-military goal when it kicked off a literal military operation by crippling Hezbollah communications and (literally crippling) hundreds/thousands of their fighters before a land invasion of the southern border areas of Lebanon. And in any case, all war is politics.
