From the New York Times:

A panel of six military officers convicted a former driver for Osama bin Laden of a war crime Tuesday, completing the first military commission trial here and the first conducted by the United States since the end of World War II.

The military commission conviction of the former driver, Salim Ahmed Hamdan, a Yemeni who was part of a select group of drivers and bodyguards for Mr. bin Laden until 2001, was a long-sought, if some what qualified, victory for the Bush administration, which has been working to begin military commission trials at the isolated naval base here for nearly seven years.

The commission acquitted Mr. Hamdan of a conspiracy charge, arguably the more serious of two charges he faced, but convicted him of a separate charge of providing material support for terrorism.
