"The document indicates that 13,000 chemical bombs were dropped by the Iraqi Air Force between 1983 and 1988, while Iraq has declared that 19,500 bombs were consumed during this period. Thus, there is a discrepancy of 6,500 bombs. The amount of chemical agent in these bombs would be in the order of about 1,000 tonnes. In the absence of evidence to the contrary, we must assume that these quantities are now unaccounted for. "
