WASHINGTON (AP) – The Pentagon said Monday that it had charged five terror suspects detained at Guantanamo Bay, Cuba, with offenses, and that they would face trial by a military tribunal.

That brings to nine the number of Guantanamo Bay detainees who have been charged with criminal offenses. There are about 500 detainees there, many captured in Afghanistan more than three years ago.

The five whose charges were announced Monday are Ghassan Abdullah al Sharbi and Jabran Said bin al Qahtani of Saudi Arabia; Sufyian Barhoumi of Algeria; Binyam Ahmed Muhammad of Ethiopia and Omar Ahmed Khadr of Canada.

The Canadian is charged with conspiracy to commit murder by an unprivileged belligerent, attempted murder by an unprivileged belligerent and aiding the enemy.

The four others are charged with conspiracy to commit several offenses: attacking civilians, attacking civilian objects, murder by an unprivileged belligerent, destruction of property by an unprivileged belligerent and aiding the enemy.
