BAGHDAD (CNN) -- A series of car bombings across Iraq on Monday killed at least 25 people and wounded more than 170 others, police said.
The 24 attacks took place in Baghdad, Kirkuk, Baquba, Tuz Khurmato and Hilla.
Two of the bombings pummeled a checkpoint near Baghdad's international airport.
Most of the attacks in Baghdad targeted Shiite areas, police told CNN. Al Qaeda in Iraq, made up of Sunni extremists, has claimed responsibility for many attacks in recent months.
Attacks elsewhere hit security checkpoints, Shiite areas and political offices.
With provincial elections scheduled to take place in five days, ongoing attacks have politicians anxious that violence could skew the outcome. Iraqis fearing attacks targeting polling centers could stay at home and abstain from voting.
