It's still brutal in Iraq. U.S. soldiers are still dying -- and there's still no end in sight:
Six U.S. soldiers were killed on Wednesday when a house rigged with explosives blew up north of Baghdad during a new U.S.-Iraqi offensive targeting al Qaeda guerrillas in Iraq, the U.S. military said.
It was one of the highest daily death tolls for U.S. troops in Iraq for months and followed the deaths of three soldiers in the operation a day earlier. More than 3,900 U.S. soldiers have been killed in Iraq since the U.S.-led invasion in 2003.
