WASHINGTON - The Pentagon announced Monday that war crime charges carrying a life sentence have been brought against an Iraqi held at the Guantanamo Bay prison. Abd al-Hadi al-Iraqi is accused of "perfidy" for having allegedly worked with late Al-Qaeda leader Osama bin Laden to attack US and coalition forces as well as civilians in Afghanistan and Iraq. He is also said to have served as an intermediary between Al-Qaeda and other extremist groups like the Taliban. Iraqi faces life in prison if convicted by a military commission tribunal.
