From the [1] Pakistan Tribune, "4 Day Operation Ended in Western Iraq"

U.S. and Iraqi forces have ended a four-day operation, Spear, aimed at clearing insurgent bases and training camps in western Iraq.

Military officials say forces killed some 50 fighters and discovered more than a dozen car bombs in and around the town of Karabilah during the campaign.

U.S. officials also say a roadside bomb killed an American soldier in a separate incident in western Iraq.

Meantime, a top U.S. military commander, General John Vines, says some U.S. forces may begin leaving the country after elections scheduled for later this year.
