With a judge’s permission, the self-styled mastermind of the Sept. 11 attacks is wearing camouflage at his Guantanamo military tribunal.

Khalid Sheikh Mohammed sported a camouflage vest over a white tunic Wednesday as he sat at his defense table in a heavily guarded courtroom on the U.S. base in Cuba.

Mohammed and one other defendant attended the pretrial motions hearing. Three defendants chose to stay in their cells. The five are charged with planning and aiding the worst terrorist attack on U.S. soil.

His lawyers said previously that Mohammed considers himself a prisoner of war and wanted to wear clothing similar to what he wore as a mujahedeen fighter. The judge in his terrorism trial ruled Tuesday he could wear camouflage. The prison commander had previously forbidden it.
