The accounts of civilian deaths among nearly 400,000 purported Iraq war logs released Friday by the WikiLeaks website include deaths unknown or unreported before now -- as many as 15,000 by the count of one independent research group.
The field reports from U.S. forces and intelligence officers also indicate U.S. forces often failed to follow up on credible evidence that Iraqi forces mistreated, tortured and killed their captives as they battled a violent insurgency.
The documents represent the largest leak of secret information in U.S. history.
