Chicago (CBS) -- On a day of national celebration, there was a bloody stain to Iraq's takeover of security. There was carnage on the streets after a car bomb exploded in a crowded outdoor market in Kirkuk. At least 30 people died. However, this time, U.S. soldiers did not respond because the Iraqis are now in charge of security.

CBS 2's Anne State reports that some native Iraqis in Chicago are predicting even more violence: a civil war involving the Sunni, Shia and Kurds.
