Obama marks end of Iraq war at U.S. base

U.S. President Barack Obama was among those marking the end of the war in Iraq at a special ceremony Tuesday.

The president was joined by vice president Joe Biden at Joint Base Andrews in Maryland toparticipate in a ceremony welcoming home U.S. troops from Iraq, and marking the end of the war.

The last U.S. combat troops rolled out of Iraq across the border into neighboring Kuwait at daybreak on Dec. 18, ending nearly nine years of war.

During the war, nearly 4,500 Americans were killed, about 32,000 were wounded and hundreds of billions of dollars were spent.
