Head of the UN weapons inspections team Hans Blix concluded two days of talks with Iraqi leaders on 9 February saying that there had been indications of a willingness to improve co-operation, but 'no breakthrough'. Two signs he highlighted were the provision of documents relating to weapons programmes, and private interviews with Iraqi scientists - although he described the quality of these meeting so far as a 'mixed bag'. A agreement to allow U2 surveillance planes to fly over Iraq had not yet been reached, but Iraqi Presidential adviser Amar al-Saadi told a news conference that an answer would be given before 14 February, when Blix presents his second report to the UN Security Council.
