 Five things you need to know about the rules of war. Civilians must be protected. It is illegal to target civilians and civilian objects, things like homes, schools and hospitals. The sick and wounded must be cared for regardless of whose side they're on, like soldiers, the shipwrecked, civilians and medical staff. Detainees are also protected under international humanitarian law. This includes protection from acts of violence and intimidation and special protection is given to prisoners of war. All those who've died must be treated with dignity. Under international humanitarian law, warring parties must facilitate the return of the dead to their loved ones. Humanitarian aid, like food, water and medicine, must be able to reach people. So parties to a conflict must facilitate humanitarian access. And most importantly, the rules of war must be applied without discrimination, regardless of a person's race, sex, nationality, political opinion or religion.
