Apparently, no less that SIX Americans and 2 Britons have been detained in Iraq on suspicion of participating in paramilitary attacks on American forces. Officials of the US occupation forces are withholding details of their identities so far. I will update as more information becomes available. For some reason the major news websites are not running this yet.
UPDATE: The eight prisoners have been classified as security detainees and are being held at Abu Ghraib prison, about 20km west of Baghdad. Obviously they are being interrogated and until that is done (a process that could last days), no details about their identities will be released.
