What is the difference between War Crimes and Crimes Against Humanity?

War crimes are serious violations of the customary and treaty laws concerning international humanitarian law. These are now considered infractions that employ personal responsibility. It may be explained as the breach of established protocols and arrangements and the violation of rules and methods during a war.
Violence toward civilians is considered war crimes.

Crimes against humanity include any crime which threatens the integrity of groups of people as a whole. It involves the humiliation or shame of one or more human beings. These crimes can be a part of the norm, as in a part of government policy. The purposeful destruction of humans based on their culture, race, religion, or political beliefs also encompasses crimes against humanity. A specific example of this is the Holocaust.

A war crime is any form of measure that accounts for a breach of the laws governing war and which in turn influence individual criminal accountability. Crimes against humanity are also specific measures that are aimed mainly as part of a universally committed attack fashioned against any part of the human population. Some of the factors which differentiate war crimes from crimes against humanity include: War crimes that can only occur in the process of armed conflict; meanwhile, crimes against humanity can both happen during wars and serene moments. Also, a crime against humanity can either be aimed at citizens of any state even the state's own citizens, if they also partake in the attack, many war crimes are aimed specifically at both citizens and rival troops. However, virtually all of the basic offenses which would normally validate crimes against humanity can also validate a war crime provided that all other factors are constant, but the converse is not always so.
