Hans Blix and Mohamed ElBaradei presented several reports to the UN detailing Iraq's level of compliance with Resolution 1441. On 27 January 2003 Chief UN Weapons Inspector Blix addressed the UN Security Council and stated "Iraq appears not to have come to a genuine acceptance–not even today–of the disarmament, which was demanded of it and which it needs to carry out to win the confidence of the world and to live in peace." Blix went on to state that the Iraqi regime had allegedly misplaced "1,000 tonnes" of VX nerve agent—one of the most toxic ever developed.
