Newsweek article link
I can't find a direct link to the original Newsweek article cited above, but this Common Dreams page appears to reproduce it in its entirety.
Hussein Kamel, the highest-ranking Iraqi official ever to defect from Saddam Hussein’s inner circle, told CIA and British intelligence officers and U.N. inspectors in the summer of 1995 that after the gulf war, Iraq destroyed all its chemical and biological weapons stocks and the missiles to deliver them.
