Resolution 1441 stated that Iraq was in material breach of the ceasefire terms presented under the terms of Resolution 687. Iraq's breaches related not only to weapons of mass destruction (WMD), but also the known construction of prohibited types of missiles, the purchase and import of prohibited armaments, and the continuing refusal of Iraq to compensate Kuwait for the widespread looting conducted by its troops during the 1990–1991 invasion and occupation. It also stated that "...false statements or omissions in the declarations submitted by Iraq pursuant to this resolution and failure by Iraq at any time to comply with, and cooperate fully in the implementation of, this resolution shall constitute a further material breach of Iraq's obligations."
