An American student who was imprisoned in Saudi Arabia for the last 20 months was returned to the United States and accused by the Justice Department on Tuesday of plotting with members of Al Qaeda in 2003 to assassinate President Bush. In an indictment unsealed in federal court in Alexandria, Va., the student, a 23-year-old American citizen named Ahmed Omar Abu Ali, is charged with providing material support for terrorism. Mr. Abu Ali is accused of training with Al Qaeda overseas and wanting to "become a planner of terrorist operations" like Mohammed Atta or Khalid Shaikh Mohammed, two Qaeda leaders central to the Sept. 11, 2001, attacks.The indictment's accusations rely mainly on the testimony of several unnamed co-conspirators. While American officials said they took the threat seriously, the indictment suggests that any plot to assassinate Mr. Bush did not move beyond the discussion stages among extremists in Saudi Arabia, and Mr. Abu Ali was not charged under the federal statute on assassinations.
Friends of Mr. Abu Ali and defense lawyers denied that he was part of any terrorist plot and accused the Justice Department of an overzealous prosecution. They said that Mr. Abu Ali, a valedictorian at an Islamic high school in suburban Washington, was the victim of torture at the hands of the Saudis after his arrest there in June 2003, an assertion that a federal judge in Washington appeared to validate in a recent ruling in a lawsuit brought by Mr. Abu Ali's family to force his release.
