Iraq will unleash thousands of suicide attackers against the United States if U.S. troops invade, a senior Iraqi official was quoted today as saying.

Vice President Taha Yassin Ramadan said in an interview with a German magazine that Iraq's ability to withstand U.S. military might was "unlimited" and that U.S. ground troops would face tough resistance.

"We have no long-range missiles or bomber squadrons, but we will deploy thousands of suicide attackers," Ramadan told the weekly Der Spiegel. "These are our new weapons, and they will be used not only in Iraq."

Other Arab countries would help defend Iraq in case of war, inflaming the entire Middle East, he said. "This part of the world will become a sea of resistance and danger for the Americans."

Ramadan reiterated Iraq's insistence that it no longer has weapons of mass destruction and said his country is not working on an atomic bomb.

U.N. inspectors "can dig around wherever they want, but they won't find anything because there simply isn't anything there anymore," he said.

Despite such denials, German intelligence officials believe Iraq has truck-borne labs for making chemical or biological weapons, another German magazine reported.

Reports of mobile labs for biological weapons have surfaced in the past. Defense Secretary Donald H. Rumsfeld said last year that Iraq had the technology to make them, and other U.S. officials and former U.N. weapons inspectors have said that Saddam Hussein's government has probably developed them.
