An accurate count of Iraqi deaths has been difficult to obtain, but one respected group puts its rough estimate at closer to 50,000. And at least one expert was skeptical of the new findings.

"They're almost certainly way too high," said Anthony Cordesman of the Center for Strategic & International Studies in Washington. He criticized the way the estimate was derived and noted that the results were released shortly before the Nov. 7 election.

"This is not analysis, this is politics," Cordesman said.

The work updates an earlier Johns Hopkins study _ that one was released just before the November 2004 presidential election. At the time, the lead researcher, Les Roberts of Hopkins, said the timing was deliberate. Many of the same researchers were involved in the latest estimate.
