Scientist with ties to terrorist group goes free

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.

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.
