Khalid Sheik Mohammed, the self-proclaimed mastermind of the Sept. 11, 2001, terrorist attacks, will be tried in a military commission at Guantanamo Bay prison, according to reports.

The Washington Post’s Peter Finn reports:

Khalid Sheik Mohammed and four-co-defendants accused of planning the Sept. 11, 2001 attacks will be prosecuted in a military commission, a decision that reverses the Obama administration’s long-held goal of bringing the men to trial in federal court as part of its overall strategy of closing the military detention center at Guantanamo Bay, Cuba.

CBS News, citing an anonymous source, reported that U.S. Attorney General Eric H. Holder Jr. would announce the plan Monday afternoon. Citing U.S. officials they did not name, Reuters and the Associated Press also reported that Mohammed will be tried at Guantanamo Bay prison.

The announcement marks a reversal from the Obama administration’s earlier goals of trying Mohammed in civilian court and closing the military prison in Cuba.

In November, Holder announced that Mohammed and four other alleged Sept. 11 attack plotters would be tried in New York City, but the plan was abandoned after overwhelming public disapproval.

The decision comes nearly a month after President Obama signed an executive order creating a formal system of indefinite detention for those heled at the U.S. military prison.
