A suicide attack is a deliberate attack in which the perpetrators knowingly sacrifice their own lives as part of the attack. These attacks are often associated with terrorism or military conflicts and are considered a form of murder–suicide. Suicide attacks involving explosives are commonly referred to as suicide bombings. In the context of terrorism, they are also commonly referred to as suicide terrorism. While generally not inherently regulated under international law, suicide attacks in their execution often violate international laws of war, such as prohibitions against perfidy or targeting civilians.
