Indiscriminate attacks and weapons

As a principle of international humanitarian law, armed focres are obliged to make a distinction between:

combatants and non-combatants
military objects and civilian objects

Attacks may only be targeted at combatants and military objectives. Any wilful breach of this principle will constitute a war crime. Therefore, it is prohibited to:

launch indiscrimnate attacks that do not or cannot distinct between combatants, military objects and civilians or civilian objects
use methods or means of warfare that by their nature are incapable of distinguishing between civilians, civilian objects and combatants and military objects
