Accused al Qaeda operative Ali al-Marri is seen in this photograph taken in January 2009 at a U.S. Navy brig in Charleston, South Carolina. Al-Marri, who was held in isolation in the U.S. Navy brig for six years, pleaded not guilty to terrorism charges in an appearance in federal court on March 23, 2009. Ali al-Marri, a 43-year-old with dual citizenship in Qatar and Saudi Arabia, was originally arrested in Peoria in December 2001 in an investigation of the Sept. 11 hijacked plane attacks, and in 2003 was branded an "enemy combatant" and kept in isolation in a military prison.
