At least one person was killed and 11 others were wounded when two explosive devices detonated in the northern Iraqi city of Kirkuk on Saturday morning, the city's police said.
The attack targeted a marketplace in the southern part of the city, police said.
Iraq has been engulfed in fighting and political instability in recent months. The United Nations said 2013 was the deadliest year in Iraq since 2008, with almost 8,000 people killed, most of them civilians. On Wednesday, at least 61 people were killed and scores wounded in the latest wave of attacks in the Iraqi capital and across the country.
Fears of all-out sectarian war have increased since violence broke out in Anbar province, where al Qaeda-backed militants and Iraq's security forces have been battling for control of Falluja and Ramadi.
The violence recalls the bloody fighting at the height of the Iraq war that nearly tore the country apart.
