British bombers attack Nuremberg

A suicide attack (also known by a wide variety of other names, see below) is a deliberate attack in which the perpetrators intentionally end their own lives as part of the attack. These attacks are a form of murder–suicide that is often associated with terrorism or war. When the attackers are labelled as terrorists, the attacks are sometimes referred to as an act of suicide terrorism. Military use of suicide is not directly regulated by international law, but suicide attacks sometimes violate prohibitions against perfidy or targeting civilians. Suicide attacks have occurred in various contexts, ranging from military campaigns—such as the Japanese kamikaze pilots during World War II (1944–1945)—to more contemporary Islamic terrorist campaigns—including the September 11 attacks in 2001.
