If you are short on time, or disinclined to leave this page, here are some excerpts from an article about the report, which were published on Sunday, September 8, 2002 by the Sunday Herald (Scotland).

"Reports by the US Senate's committee on banking, housing and urban affairs -- which oversees American exports policy -- reveal that the US, under the successive administrations of Ronald Reagan and George Bush Sr, sold materials including anthrax, VX nerve gas, West Nile fever germs and botulism to Iraq right up until March 1992, as well as germs similar to tuberculosis and pneumonia. Other bacteria sold included brucella melitensis, which damages major organs, and clostridium perfringens, which causes gas gangrene....

The reports show, for example, that on May 2, 1986, two batches of bacillus anthracis -- the micro-organism that causes anthrax -- were shipped to the Iraqi Ministry of Higher Education, along with two batches of the bacterium clostridium botulinum, the agent that causes deadly botulism poisoning....

One batch each of salmonella and E coli were shipped to the Iraqi State Company for Drug Industries on August 31, 1987. Other shipments went from the US to the Iraq Atomic Energy Commission on July 11, 1988; the Department of Biology at the University of Basrah in November 1989; the Department of Microbiology at Baghdad University in June 1985; the Ministry of Health in April 1985 and Officers' City, a military complex in Baghdad, in March and April 1986...The Senate report also makes clear that: 'The United States provided the government of Iraq with 'dual use' licensed materials which assisted in the development of Iraqi chemical, biological and missile-system programs."

This assistance, according to the report, included 'chemical warfare-agent precursors, chemical warfare-agent production facility plans and technical drawings, chemical warfare filling equipment, biological warfare-related materials, missile fabrication equipment and missile system guidance equipment'."
