War crimes refer to serious violations of international humanitarian law committed during times of war. These acts include, but are not limited to, murder, torture, rape, and the intentional targeting of civilians or civilian property. War criminals can be individuals, such as soldiers or military leaders, who commit these atrocities, or even entire organizations that order or condone them. The international community considers war crimes to be serious offenses, and perpetrators may face prosecution and punishment in accordance with relevant laws and treaties.
