Khalid Sheikh Mohammed, the accused chief plotter of the Sept. 11, 2001, terrorist attacks, returned to court today after voluntarily skipping yesterday’s hearing at the U.S. Navy base in Guantanamo Bay, Cuba.

Mohammed for the first time wore a military-style camouflage vest, a day after the military judge ruled that such attire would be permitted as long as it’s not a part of any U.S. military uniform.

Mohammed’s attorney yesterday argued for the right to wear such clothing, saying it resembles what the defendant wore as a member of the Mujuahadeen force in Afghanistan when it was under Soviet occupation. Prosecutors opposed the measure, saying camouflage could pose a security threat if it could be confused with a U.S. military uniform.
