Baghdad on 3 March pledged to submit a report to UN weapons inspectors on the fate of its stocks of anthrax and VX gas in 'about a week,' potentially slowing the US' march towards war. Inspectors say that about 2.4 tonnes of VX gas remain unaccounted for, but Iraq's chief scientific adviser, Amer al-Saadi, said on 2 March that DNA testing would be used to help verify that stockpiles of both chemicals had been destroyed. Head of the inspections team Hans Blix is scheduled to give his next progress report to the UN Security Council on 7 March, based on a draft report presented on 27 February which described Iraqi steps towards disarmament as 'very limited'. Since the criticism, Baghdad has begun destroying its Al-Samoud II missiles as demanded. Both the US and the UK have dismissed moves on co-operation as irrelevant concessions, falling far short of President Saddam Hussein's obligations under Resolution 1441.
