BAGHDAD, Iraq (CNN) - Tuesday marked the deadline for American troops to pull out of Iraq's towns and cities - a long-anticipated date that has been met by street festivals in Baghdad.
Celebrations were tempered, however, by fears of renewed violence as insurgents seek to use the date to stage new attacks.
At least 30 people, including women and children, were killed and 45 wounded Tuesday in a bombing in northern Iraq, a local police official said.
The blast took place in a busy commercial area in a predominantly Kurdish part of Kirkuk, destroying 20 shops and houses, the official said. Kirkuk is about 235 miles north of Baghdad.
