U.S. teams test for chemical, biological arms in Afghanistan

WASHINGTON -- U.S. teams are searching and taking samples from sites in Afghanistan where the al-Qaida terrorist network may have been building chemical or biological weapons, a top Pentagon official says.

Marine Corps Gen. Peter Pace said U.S. forces have visited some, but not all, areas where al-Qaida may have been making such weapons of mass destruction. Results of tests from those sites have not come back yet, Pace said Wednesday.

"That one place where the only vial that had English on it said 'anthrax' kind of gives you pause," said Pace, vice chairman of the Joint Chiefs of Staff. "We are going to have the analysis, and don't have that yet."

Sept. 11 attacks suspect Osama bin Laden, al-Qaida's leader, has said his group has chemical, biological and even nuclear weapons. U.S. officials have said al-Qaida probably has crude chemical or biological weapons but not a nuclear bomb.

U.S. planes have bombed sites that officials believe could have been used to produce chemical or germ weapons. U.S. airstrikes hit a laboratory in Kabul that worked with anthrax, for example. Scientists at the lab say they only made anthrax vaccines for livestock.

Bombing's success

Two journalists killed in Afghanistan on Monday had reported finding what they believed were glass vials of deadly sarin nerve gas at an abandoned al-Qaida camp southwest of Jalalabad, an eastern city near the border with Pakistan.

At other sites abandoned by the Taliban or al-Qaida, reporters have found guides to making chemical and biological weapons.

Defense Secretary Donald H. Rumsfeld visited special operations troops at Fort Bragg, N.C., Wednesday to thank them for their service. Special forces in Afghanistan have helped guide bombs to targets and given anti-Taliban forces advice and supplies.

"The success of the targeting has just improved so dramatically" since special forces landed in Afghanistan, Rumsfeld told the soldiers: "The air war enabled the ground war to succeed."
