United Nations weapons inspectors say Iraq appears to be making new efforts to co-operate with UN teams searching for banned weapons. Chief inspector Hans Blix was speaking after Baghdad allowed one of its scientists to be interviewed alone for the first time. But he warned that he wanted to see a lot more co-operation when he visits Iraq this weekend. Blix and fellow chief inspector Mohamed ElBaradei are due to present a key report on Iraqi co-operation to the UN Security Council on 14 February, triggering what many believe could be a countdown to war. Suggestions of Iraqi concessions were denounced in advance by President George W Bush, who said he expected new attempts by Baghdad to delay and confuse the situation.
