A group of 40 to 60 insurgents attacked the Abu Ghraib prison in Iraq late Saturday in a well-coordinated assault that inflicted 18 American casualties, U.S. military officials told NBC News.

The officials, who spoke on condition of anonymity, could not immediately provide a breakdown on the number of dead or wounded.
