In news from Iraq, the website Iraq Body Count has released a study that estimates that as many as 616 Iraqi civilians were killed in April during the U.S. siege of Fallujah. A total of about 800 Iraqis died in the U.S.-backed attack. Until now no group has attempted to calculate the civilian cost of the siege. Meanwhile at least three people died in Fallujah today in a U.S. bombing that destroyed several houses. Meanwhile the New York Times is reporting a major new U.S.-led attack on Fallujah is imminent. The Times said the offensive will likely be the largest and potentially the riskiest operation in Iraq since the end of major combat.
