The overwhelming majority of cases of unlawful killings and injuries in Israel and the Occupied Territories have been committed by the IDF using excessive force. In particular, the IDF have used US-supplied helicopters in punitive rocket attacks where there was no imminent danger to life. Israel has also used helicopter gunships to carry out extrajudicial executions and to fire at targets that resulted in the killing of civilians, including children. ... Hamas and Islamic Jihad have frequently placed bombs in public places, usually within Israel, in order to kill and maim large numbers of Israeli civilians in a random manner. Both organizations have fostered a cult of martyrdom and frequently use suicide bombers.
