Blix's March 7 presentation to the UN SC is [link|http://www.un.org/Depts/unmovic/SC7asdelivered.htm|here]. It says:
There is a significant Iraqi effort underway to clarify a major source of uncertainty as to the quantities of biological and chemical weapons, which were unilaterally destroyed in 1991. A part of this effort concerns a disposal site, which was deemed too dangerous for full investigation in the past. It is now being re-excavated. To date, Iraq has unearthed eight complete bombs comprising two liquid-filled intact R-400 bombs and six other complete bombs. Bomb fragments were also found. Samples have been taken. The investigation of the destruction site could, in the best case, allow the determination of the number of bombs destroyed at that site. It should be followed by a serious and credible effort to determine the separate issue of how many R-400 type bombs were produced. In this, as in other matters, inspection work is moving on and may yield results.
Iraq proposed an investigation using advanced technology to quantify the amount of unilaterally destroyed anthrax dumped at a site. However, even if the use of advanced technology could quantify the amount of anthrax, said to be dumped at the site, the results would still be open to interpretation. Defining the quantity of anthrax destroyed must, of course, be followed by efforts to establish what quantity was actually produced.
Cheers,
Scott.
