Protected persons is a legal term under international humanitarian law and refers to persons who are under specific protection of the 1949 Geneva Conventions, their 1977 Additional Protocols, and customary international humanitarian law during an armed conflict.
Medical personnel during an armed conflict carry out humanitarian work and are "protected persons" under international humanitarian law. Whether military or civilian, they are considered non-combatants and may not be attacked and not be taken as prisoners of war by parties to a conflict. They use a protective sign such as the red cross, red crescent or red crystal.
International humanitarian law
International humanitarian law (IHL), also referred to as the laws of armed conflict, is the law that regulates the conduct of war. It is a branch of international law that seeks to limit the effects of armed conflict by protecting persons who are not participating in hostilities and by restricting and regulating the means and methods of warfare available to combatants.
