In this CNN story about the deaths in the Chinook crash (back up to 16 today):
The deaths bring the number of U.S. troop fatalities in Iraq to 384, including 245 since President Bush declared an end to major combat on May 1.
There is no reliable source for Iraqi civilian or combatant casualty figures, either during the period of major combat or after May 1. The Associated Press reported an estimated 3,240 civilian Iraqi deaths between March 20 and April 20, but the AP reported that the figure was based on records of only half of Iraq's hospitals and the actual number was thought to be significantly higher.
I don't remember any CNN stories mentioning Iraqi death tolls since the "end of major combat operations".
