The United Nations has this introduction to the subject of mines and disarmament:
Landmines come in two varieties: anti-personnel and anti-vehicle mines. Both have caused great suffering in the past decades. Anti-personnel landmines are prohibited under the Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on Their Destruction (or Mine Ban Convention), adopted in 1997. More than 150 countries have joined this treaty. Its positive impact includes a marked reduction of casualties, an increased number of mine-free States, destroyed stockpiles and improved assistance to victims.
The question becomes if land-mines are prohibited, aren’t drones aloft (loitering munitions that explode on some trigger mechanism) simply air-mines and thus also prohibited already?
