[The] provisions, which are outlined below, are generally recognized as being an expression of customary international law. …
The purpose of international humanitarian law is to protect the victims of war as much as possible. …
It follows from API [1977 Additional Protocol I] that military attacks that do not respect the distinction between civilians and military targets are illegal because of their indiscriminate nature. Such indiscriminate attacks are defined in API Article 51(4).

… According to the rules of international law, the use of weapons in areas with a high concentration of civilians, for example in urban areas, can be described as an indiscriminate attack and thus contravene international law. The degree of risk that the use of a given weapons constitutes an arbitrary attack is closely linked to the issue of the weapon’s precision and technical reliability. The lesser the accuracy and reliability, the more likely it is that the use of a weapon will have the character of an arbitrary attack.
