The leader of the al-Qaida-affiliated Islamic State of Iraq, Abu Omar al-Baghdadi, has been captured in a raid west of Baghdad, an Iraqi military spokesman said Friday. US officials had no confirmation of the statement by Brig. Gen. Qassim al-Moussawi, spokesman of the Baghdad security operation. Al-Moussawi said al-Baghdadi was captured Friday in a raid in Abu Ghraib on the western outskirts of Baghdad. "One of the terrorists who was arrested with him confessed that the one in our hands is al-Baghdadi," al-Moussawi said.
