WASHINGTON -- The U.S. has reportedly reached a plea deal with a former Maryland man held at Guantánamo accused of joining al-Qaida and participating in a series of post-Sept. 11 terror plots.

The Washington Post reported Wednesday that Pakistani captive Majid Khan, 31, has reached an agreement with military prosecutors. He would receive a lesser sentence and later be freed in exchange for testifying against other detainees.

The Post cited unidentified U.S. “officials” in its report Wednesday.

Khan’s lawyers and the Pentagon declined comment. But the Pentagon’s own war court website foreshadowed the deal on Tuesday by posting the title of a memo from prosecutors and defense attorneys that was under seal at the Defense Department, “Joint Motion in Regards to Sentencing and Docket Schedule.”

Khan is scheduled to be arranged Feb. 29 at the U.S. base in Cuba, one day after his 32nd birthday. The military has accused him of researching underground U.S. fuel tanks as potential terror targets, acting as a cash courier ahead of an al Qaida affiliate terror attack in Jakarta, Indonesia, and plotting to kill then President Pervez Musharraf of Pakistan.

Khan is a former U.S. resident who graduated from a Baltimore area high school in the 1990s before moving to his native Pakistan. He has been a U.S. captive for nearly a decade.

The Khan case lead prosecutor is civilian Courtney Sullivan, a Justice Department lawyer who specializes in National Security cases.

His defense team includes Army Lt. Col. Jon Jackson, who had earlier defended an alleged co-conspirator in the Sept.11 attacks and also struck a plea deal for Canadian Omar Khadr, still at Guantánamo; Wells Dixon of the Center for Constitutional Rights, who’s represented Khan longest; and Katya Jestin of Jenner and Block, a former federal prosecutor.
