Also called "Law of Armed Conflict", as noted in the cited references.

International humanitarian law, the jus in bello, concerns the way wars may be fought. It is distinct from the law governing when wars may be fought (the jus ad bellum of self-defence and the UN Charter). Also known as the 'laws of war', international humanitarian law traces its origins to 1859, when the Swiss businessman Henri Dunant witnessed the aftermath of the Battle of Solferino and initiated a movement that became the International Committee of the Red Cross. Today, the rules of international humanitarian law are found in the 1907 Hague Conventions, the 1949 Geneva Conventions and their two Additional Protocols of 1977, as well as in a parallel body of unwritten customary international law that binds all countries, including those that have not ratified the Conventions and Protocols. A central principle prohibits the direct targeting of civilians, as well as attacks on military targets that could be expected to cause civilian suffering disproportionate to the specific military goals to be acheived.
