Iraqi officials say car bombings have killed at least five people, the day after a wave of violence left at least 50 people dead across the country.
The deadliest bombing Tuesday hit Aziziyah, about 75 kilometers south of the capital, Baghdad. That blast killed at least four people and wounded 15 others.
North of Baghdad, another explosion killed at least one soldier.
There was no immediate claim of responsibility for the attacks, which come as Iraqis prepare to vote in provincial elections on Saturday. The vote is the first in Iraq since U.S. troops withdrew from the country in December 2011.
The election has already been postponed by several months in Anbar and Ninevah provinces because of security threats.
