Among the most serious is the charge that Iraqi forces tortured prisoners without restraint from the US authorities. The United Nations has called for an investigation into whether US commanders knew of this: already, the evidence from many of the leaked war logs, in which US troops noted abuses by Iraqi forces, suggests that often they did. So too does the existence of “Frago 242”, an order issued in June 2004, indicating that coalition troops should not investigate any breach of the laws of armed conflict unless it directly involved coalition members.
