Australian David Hicks, known as the "Aussie Taliban", poses for a photograph in Sydney November 6, 2013. Hicks was so desperate to get out of the Guantanamo prison that he pleaded guilty under duress to a charge that was not actually a war crime, his lawyers said in an appeal filed on Tuesday. During his five years at Guantanamo, Hicks was beaten, threatened with deadly violence, sexually assaulted, deprived of sleep for long periods and told that he would never again set foot in his native land, his lawyers said.

Terry Hicks (L) is comforted by his wife Bev after talking to reporters about his son's, David Hicks, appearence before a military commission at the Guantanamo Naval Base August 25, 2004. David Hicks, formally charged on Wednesday with war crimes by a U.S. military tribunal, pleaded not guilty. David, a 29-year-old convert to Islam who was arrested during the U.S.-led war in Afghanistan in late 2001, sat stone-faced through a daylong hearing as his lawyers challenged whether the panel could try him fairly on charges of plotting attacks against America and its allies. He is among the first four suspected al Qaeda fighters held at a remote U.S. naval base at Guantanamo Bay, Cuba, to face criminal charges of conspiring to commit war crimes, and the second to appear before a military tribunal this week for pretrial hearings.
