(NYT) – Under unusual pressure from Israel and the United States, the United Nations secretary general, Ban Ki-moon, opted not to include either Israel or Hamas on a list of armies and guerrilla groups that kill and maim children in conflicts worldwide, despite the recommendations of one of his senior envoys, diplomats say. The list was part of an annual report of violations of children’s rights, an advance copy of which was circulated to members of the Security Council on Monday morning, that goes into great detail on the actions of Israeli security forces during the 50-day war in the Gaza Strip last year. The report raised what it called “serious concern over the observance of the rules of international humanitarian law concerning the conduct of hostilities.”
