Killing a wounded soldier is a War crime under the Geneva Conventions.

Under Article 85(3)(e) of the 1977 Additional Protocol I, “making a person the object of attack in the knowledge that he is hors de combat” is a grave breach of the Protocol.

“Hors de combat" is a term used in international humanitarian law (IHL ) which describes a soldier who cannot fight due to being sick, wounded, captured or incapacitated. These soldiers are not allowed to be attacked or harmed because they pose no threat.
