A more thorough explanation:

Humanitarian law is a type of international law that deals with how wars are fought and how people are treated during armed conflicts. It includes rules about the use of weapons, treatment of prisoners of war, and protection of civilians.

For example, the Geneva Conventions and their protocols outline specific rules for how prisoners of war should be treated, such as providing them with medical care and allowing them to communicate with their families. These rules are in place to ensure that even in times of war, people are treated with dignity and respect.

Another example of humanitarian law is the prohibition of certain weapons, such as chemical and biological weapons, that cause unnecessary suffering and harm to civilians.

Overall, humanitarian law aims to minimize the impact of war on human life and liberty, and to ensure that even in times of conflict, people are treated with humanity and compassion.
