Where Did Iraq Fail With U.N.?

March 18, 2003 -- Iraq has failed to abide by all of the terms of U.N. Resolution 1441, which gave Iraq a final opportunity to disarm, according to U.S. officials. Here's a summary of key remaining issues where Iraq has not complied with the resolution.

Account for almost 4 tons of VX nerve gas allegedly produced and unilaterally destroyed, detail the weaponization of VX, and account for some 600 tons of ingredients used in the manufacture of VX, which Iraq also claims to have destroyed.

Account for at least 7,000 liters of anthrax and 4 tons of growth media used in the production of anthrax.

Account for at least 50 Scud warheads, including 25 filled with biological agent.

Account for 300-350 R-400 aerial bombs, including 157 filled with biological warfare agents which it claims were destroyed in 1991.

Account for 2,000 aerial bombs which could be filled with chemical or biological agent and some 450 mustard gas-filled bombs.

Turn over a drop-tank prototype used to deliver chemical or biological weapons agents from aircraft; fully disclose the extent of their production.

On remaining Scud missiles in Iraq:

The United Nations Special Commission (UNSCOM) accounted for all but 2 of Iraq's 819 Scud-B missiles imported from the former Soviet Union. However, Iraq claims that 14 of these were used as targets in a missile interception project. UNMOVIC has raised questions about that claim.

Iraq may retain indigenously produced Scud engines, a "significant quantity" of liquid propellant, and components used in missile guidance and control.
