Nearly half of the foreign detainees held in Iraq are Saudi citizens and lists of their names were given to Saudi officials during a recent visit by an Iraqi delegation, national security adviser Mouwaffak al-Rubaie said in remarks aired Monday. Al-Rubaie's comments to Al-Arabiya television were made during a three-day visit last week to Saudi Arabia in which he met senior officials, including Interior Minister Prince Nayef. "The Iraqi government says that nearly half of the foreigners in Iraqi prisoners are from Saudi Arabia. Hundreds of them are in Camp Bucca and other prisons controlled by coalition forces," al-Rubaie said. He did not give a total figure of Saudi detainees. In Iraq, the US Army is holding thousands of prisoners at Camp Cropper near Baghdad airport and in Camp Bucca in the southern desert.
