Grieving Iraq family sees no end to "rivers of blood"

BAGHDAD (Reuters) - Adel Abed Hammed was a skinny 31-year-old so withdrawn he sometimes went days without talking to anybody and would let only his mother touch him. 

Mentally ill since childhood, he used to wander the streets of Baghdad alone. One day he chanced on some American soldiers who shot him dead after he took fright at a bullet fired over his head.
