The United States is asking for military support from dozens of countries as it prepares for conflict in Iraq. Britain and Canada are among traditional allies who have already agreed to the request for troops and equipment. US President George W Bush urged his Nato colleagues in Europe to join a "coalition of the willing" to take action in Iraq if it defied a United Nations resolution to rid itself of any weapons of mass destruction. But the UN chief weapons inspector Hans Blix - who has held talks in Baghdad under the terms of that resolution - said he was confident that war against Iraq can "still be averted".
