Powell to offer evidance of Iraq's defiance

US Secretary of State Colin Powell will present photographs of mobile biological weapons and transcripts of overheard Iraqi conversations to convince allies that Saddam Hussein has potent arsenals in defiance of UN disarmament demands, an administration official said.

Mr Powell sifted through classified US intelligence yesterday to choose what he will make public tomorrow to the UN Security Council. He is expected to display the photographs and refer to transcripts, an official told The Associated Press.
