Al Qaeda's anthrax program

Washington Post:

In December 2001, as the investigation into the U.S. anthrax attacks was gathering steam, coalition soldiers in Afghanistan uncovered what appeared to be an important clue: a trail of documents chronicling an attempt by al-Qaeda to create its own anthrax weapon.

The documents told of a singular mission by a scientist named Abdur Rauf, an obscure, middle-aged Pakistani with alleged al-Qaeda sympathies and an advanced degree in microbiology.

Using his membership in a prestigious scientific organization to gain access, Rauf traveled through Europe on a quest, officials say, to obtain both anthrax spores and the equipment needed to turn them into highly lethal biological weapons. He reported directly to al-Qaeda's No. 2 commander, Ayman al-Zawahiri, and in one document he appeared to signal a breakthrough.

"I successfully achieved the targets," he wrote cryptically to Zawahiri in a note in 1999.

Precisely what Rauf achieved may never be known with certainty. That's because U.S. officials remain stymied in their nearly five-year quest to bring charges against a man who they say admitted serving as a top consultant to al-Qaeda on anthrax -- a claim that makes him one of a handful of people linked publicly to the group's effort to wage biological warfare against Western targets.

Rauf, 47, has been under scrutiny in Pakistan since he was detained there for questioning in late 2001, according to U.S. and Pakistani officials who agreed to talk about the case for the first time. But officially he remains free, and Pakistan now says it has no grounds for arrest. Last year, in an acknowledgment of the impasse in its four-year joint investigation with Pakistan, the FBI officially put the case on inactive status.

The documents that first revealed Rauf's role were part of a large stack of papers discovered in a house after coalition forces overran an al-Qaeda base in Kandahar, in southern Afghanistan. He emerges from documents and interviews as one of the most intriguing, and in some ways most troubling, figures in an international investigation into al-Qaeda's biological weapons program.

With the evidence against Rauf, some U.S. officials say they are perplexed about why Pakistani authorities have refused to further pursue him, while acknowledging that the case presents both legal and political difficulties for Pakistan.

There is much more in the long story. Not much has been written about an al Qaeda connection to the anthrax attacks, but this promising lead has not resulted in a prosecution. It could be just another failure of the lawfare approach to terrorism. It does not appear that the suspect was put through a coercive examination.
