A ping pong table for detainees sits in the middlle of a court yard at Camp Delta at Guantanamo Naval Base August 23, 2004 in Guantanamo, Cuba. Four suspected al Qaeda fighters will be formally charged with war crimes this week as the U.S. military opens the first legal hearings for foreign prisoners captured during the war in Afghanistan and held at a remote U.S. Navy base in Cuba. [Beginning on Tuesday, the prisoners from Australia, Sudan and Yemen will appear separately, unshackled and in civilian clothing before a panel of five U.S. officers who will read the charges against them at the arraignments, officials at the Guantanamo base said on Sunday.]
