(CBS) On the verge of delivering a weapons declaration that will probably spark confrontation with the United States, Iraq Friday again denied possessing banned arms.

Iraqi Ambassador Mohammed Al-Douri said the declaration would be given to inspectors at 8 p.m. Baghdad time on Saturday and that copies would be sent by courier to U.N. headquarters in New York. A copy would reach the Security Council on Sunday, which is the deadline for Iraq's submission of the declaration.

Al-Douri said the declaration contains "a huge amount of information," some of which would not be made public.

"We said again and again that we have no more destruction weapons at all, everything has been destroyed and we have no intention to do that again," Al-Douri told reporters as the Security Council met to discuss the expected declaration. "If the Americans have this evidence, they have to tell the inspectors in Iraq to go find this evidence," Al-Douri said.

Still, Al-Douri said, "there will be new elements in the report."

The declaration will be handed to the U.N. in Baghdad on Saturday – a day early – but it will take weeks to analyze and months to verify the 13,000 of pages of documents, reports CBS News Correspondent Mark Phillips. It will also have to be translated from Arabic.

The delivery of the Iraqi declaration will open the next chapter in President Bush's drive to disarm Iraq, putting pressure both on the administration and the inspectors to make the next move.

The Bush administration insisted Thursday it has "solid" evidence that Saddam Hussein has weapons of mass destruction.

"The president of the United States and the secretary of defense would not assert as plainly and bluntly as they have that Iraq has weapons of mass destruction if it was not true, and if they did not have a solid basis for saying it," White House spokesman Ari Fleischer said Thursday.

Hans Blix, the chief U.N. weapons inspector, said he would brief the Security Council early next week on the contents of the report before releasing any part of it. Sections that are deemed sensitive would remain confidential.

"All the governments are aware that they should not have access to anything that everyone else does not have access to," Blix said after discussing the handling of the declaration with the 15 council members at a closed-door meeting.

Council diplomats said Russia and other council members were concerned that the declaration might contain "recipes" for chemical and biological weapons, and other information that could lead to the proliferation of weapons of mass destruction.

Al-Douri said the declaration contains "a huge amount of information," some of which would not be made public.

Both the Iraqi envoy and the chief inspector addressed charges by the United States that Saddam Hussein's government is hiding weapons of mass destruction.

"We said again and again that we have no more destruction weapons at all, everything has been destroyed and we have no intention to do that again," the Iraqi envoy said. "If the Americans have this evidence, they have to tell the inspectors in Iraq to go find this evidence."

Blix denied that he was under any pressure from the United States but stressed that Resolution 1441, adopted Nov. 8 to toughen U.N. inspections, asks all 191 U.N. member states to provide information to help inspectors search for banned weapons.

"We want to have recommendations from member governments what we should do," Blix said.

The chief inspector was asked about reports that the United States was pressing for the inspectors to question Iraqi scientists outside the country.

"We are not going to abduct anybody, and we're not serving as a defection agency," Blix said.

Under Resolution 1441, Iraq has until Sunday to submit a full and complete disclosure of its chemical, biological and nuclear programs.

Blix updated the council Friday on the work of his inspection teams so far in Iraq. Inspectors returned to Iraq last month after an absence of of nearly four years. "They have done a good professional job," he said.
