There's concern in the U.S. military that the Iraqi government may not be ready for the flood of refugees returning to Baghdad.
Thousands have returned to their homeland in recent weeks, mainly from Syria, largely due to the drop in overall violence and a government promise of money and free transportation.
However, their future back home is uncertain.
A senior aide to the top U.S. commander in Iraq says many of those returning "are probably going to find somebody else living in their house." In fact, many have found their houses occupied by members of a rival Islamic sect or burned to the ground. U.S. military officials say the government of Iraq doesn't have a policy yet for dealing with such things.
