In the absence of Iraq's acknowledgement of resolution 715 (1991), which delayed long-term monitoring efforts across the whole spectrum of Iraqi missile-related activities, interim monitoring of the Ibn Al Haytham Centre was initiated by the UN Special Commission to track Iraqi ballistic missile programmes to ensure that no proscribed activity was taking place. The first interim monitoring team, IMT1a, was sent into Iraq on 25 January 1993, where it spent eight weeks investigating the work of the Ibn Al Haytham Center. The focus of the IMT1a mission was in the area of liquid propulsion systems and related technologies.
Based upon the results of IMT1a, the Commission dispatched to Iraq a new team of interim monitors, IMT1b, to relieve IMT1a on 27 March 1993. The purpose of the team was mainly to investigate and assess Iraq's capabilities to produce solid propellant missile systems and to establish the relationships between the various facilities involved in such activities within the Military Industrialization Corporation. It conducted its activities over a 52-day period 27 March to 17 May 1993, centred around 2 facilities: the Al Rasheed Factory, comprising the 3 plants, and the Al Qa'qaa' Establishment. In addition, the team visited the Ibn Al Haytham Research Center, the focus of the previous monitoring team's activities, and other sites related to missile research and development in and around Baghdad.Iraq continues to expand the missile production facility at Ibn Al Haytham -- currently used to support its authorized missile programs. Two new fabrication buildings at the facility are spacious enough to house the construction of large ballistic missiles. Baghdad's claim that the buildings at Ibn al Haytham are intended to be computer and administrative facilities is inconsistent with the facility's inherent size and capacity.
