Some senior administration officials suspect that Saddam Hussein's followers have penetrated the coalition headquarters in Baghdad and passed information to guerrilla fighters. \
A defense official told The Washington Times the suspicion at this point is not based on conclusive evidence, but on supposition.
The source said some senior officials believe it is too much of a coincidence that Saddam loyalists know where and when to attack Army convoys. At times, attackers also seem to know the planned route of low-flying helicopters, more than 10 of which have been shot down since May.
