On the same day, indications came from Baghdad that Iraq was taking heed of Blix’s warning. Weapons inspectors held their first private interview – with a biologist who volunteered to undergo questioning – and UN sources said that the government was close to agreeing to the use of the surveillance planes. Blix is to visit Baghdad on 8 February to discuss the more proactive co-operation he has demanded. However, the US was quick to dismiss the Iraqi moves: President Bush said that Saddam Hussein was bound to ‘start another empty round of concessions,’ in response to increasing international pressure. Iraq has promised a detailed rebuttal of Powell’s accusations ahead of the 14 February report to the UN by Blix and head of the International Atomic Energy Agency (IAEA) Mohamed el-Baradei.
