Iraqi Foreign Minister Mr Naji Sabri today described a revised US draft resolution for disarming Iraq as a "humiliation".
"The revised US draft, which is worse [than the initial one], is a humiliation for the United Nations and the international community," Mr Sabri told Qatar's Al-Jazeera television channel.
"The draft is a declaration of war against the United Nations, and not only against Iraq. Its goal consists not only of attacking Iraq but also harming the prestige of the United Nations," Mr Sabri said.
Earlier, the United States has acknowledged it may fail to win Security Council backing for action to disarm Iraq.
The United States introduced its draft resolution on Iraqi disarmament to the full 15-member UN Security Council in a push to move to a vote, possibly next week.
Russia immediately opposed the US text, France raised strong reservations but Britain said it would co-sponsor the draft, aimed at ridding Iraq of weapons of mass destruction.
A Security Council resolution needs nine votes in favour and no veto from its five permanent members - the United States, Britain, France, Russia and China.
The revised US text drops explicit authorisation for military action if Iraq does not comply with UN arms inspections. But it contains an option for war by declaring Iraq in "material breach" of UN resolutions and threatening "serious consequences.
