WASHINGTON — American forces in Iraq are chasing down leads from captured Iraqis and documents on possible chemical and biological weapons sites, but as of Monday they had not confirmed the presence of any weapons of mass destruction, a senior administration official said.
A suspicious plant captured by American troops was still being evaluated, according to the official, who spoke on condition of anonymity.
The official said no significant information has been obtained to date from captured Iraqis, but he expects that to change as time passes.
U.S. officials are questioning two captured Iraqi generals about chemical and biological weapons, an American commander in the region said Sunday. The military also is following up on a cache of documents found by commandos in western Iraq, the Pentagon's top general said.
U.S. Central Command, which oversees the war in Iraq, said that troops were examining several "sites of interest" but that it was premature to call the plant in Najaf a chemical weapons factory.
Finding deadly chemical or biological weapons would be a coup for the United States, which says its invasion of Iraq is meant to rid Iraq of such weapons.
International opposition to the war, led by France and Germany, has focused on the view that United Nations inspectors should have been given more time to verify Iraq's claims to be free of weapons of mass destruction.
Iraq claims it destroyed all of its chemical and biological weapons and ended its nuclear weapons program shortly after the 1991 Persian Gulf War. U.N. weapons inspectors say those claims are highly suspect — and the United States says they are blatant lies.
American special operations forces found documents in western Iraq that could lead to banned weapons facilities, Air Force Gen. Richard Myers, chairman of the Joint Chiefs of Staff, said Sunday.
Myers said U.S. commandos found the papers along with a cache of millions of rounds of ammunition after a firefight Saturday, and the discovery "might save thousands of lives if we can find out exactly where and what they have."
"I just know that they have some papers that they want to exploit as quickly as possible, and we're going to do that, of course," Myers said.
U.S. Army troops on Sunday secured a 100-acre site in Najaf that could be a chemicals factory that may have made chemical weapons, U.S. officials said. The find, first reported by a journalist from the Jerusalem Post traveling with the Army, could be the first hard evidence of chemical weapons discovered during the war.
Asked at a news conference in Qatar on Sunday about reports of the chemical plant, Lt. Gen. John Abizaid of the U.S. Central Command declined comment.
"We have an Iraqi general officer, two Iraqi general officers that we have taken prisoner, and they are providing us with information," Abizaid said.
American officials are focusing on the most senior officers among the more than 2,000 captured Iraqi troops in the hunt for chemical and biological weapons. Most of the Iraqi captives are mere foot soldiers who would not know anything about the banned weapons — making the two generals probably the most valuable prisoners in U.S. custody.
Any Iraqis seized in the raids that yielded the documents Myers discussed also would be important prisoners, said Daniel Goure, a military analyst at the Lexington Institute, a Washington-area think tank.
Finding weapons of mass destruction could take a long time, military officials said, since Iraq probably worked hard to hide them.
"You shouldn't think it's going to happen tomorrow," Abizaid said.
