32. Of particular concern is the use, by combatants on both sides, of violence that placed civilians in harm's way. Much of the fighting during Operation Defensive Shield occurred in areas heavily populated by civilians, in large part because the armed Palestinian groups sought by IDF placed their combatants and installations among civilians. Palestinian groups are alleged to have widely booby-trapped civilian homes, acts targeted at IDF personnel but also putting civilians in danger. IDF is reported to have used bulldozers, tank shelling and rocket firing, at times from helicopters, in populated areas.
53. That the Israeli Defence Forces encountered heavy Palestinian resistance is not in question. Nor is the fact that Palestinian militants in the camp, as elsewhere, adopted methods which constitute breaches of international law that have been and continue to be condemned by the United Nations. Clarity and certainty remain elusive, however, on the policy and facts of the IDF response to that resistance. The Government of Israel maintains that IDF "clearly took all possible measures not to hurt civilian life" but were confronted with "armed terrorists who purposely concealed themselves among the civilian population". However, some human rights groups and Palestinian eyewitnesses assert that IDF soldiers did not take all possible measures to avoid hurting civilians, and even used some as human shields.
57. It is impossible to determine with precision how many civilians were among the Palestinian dead. The Government of Israel estimated during the incursion that there were "only dozens killed in Jenin … and the vast majority of them bore arms and fired upon
forces". Israeli officials informed United Nations personnel that they believed that, of the 52 dead, 38 were armed men and 14 were civilians. The Palestinian Authority has acknowledged that combatants were among the dead, and has named some of them, but has placed no precise estimates on the breakdown. Human rights organizations put the civilian toll closer to 20 — Human Rights Watch documented 22 civilians among the 52 dead, while Physicians for Human Rights noted that "children under the age of 15 years, women and men over the age of 50 years accounted for nearly 38 per cent of all reported fatalities".
