ISG uncovered information that the Iraqi Intelligence Service (IIS) maintained throughout 1991 to 2003 a set of undeclared covert laboratories to research and test various chemicals and poisons, primarily for intelligence operations. The network of laboratories could have provided an ideal, compartmented platform from which to continue CW agent R&D or small-scale production efforts, but we have no indications this was planned. (See Annex A.) ?ISG has no evidence that IIS Directorate of Criminology (M16) scientists were producing CW or BW agents in these laboratories. However, sources indicate that M16 was planning to produce several CW agents including sulfur mustard, nitrogen mustard, and Sarin. ?Exploitations of IIS laboratories, safe houses, and disposal sites revealed no evidence of CW-related research or production, however many of these sites were either sanitized by the Regime or looted prior to OIF. Interviews with key IIS offi cials within and outside of M16 yielded very little information about the IIS?activities in this area. ?The existence, function, and purpose of the laboratories were never declared to the UN. • The IIS program included the use of human subjects for testing purposes.
