Iraqi police say a wave of bombings in six Iraqi provinces, including 10 locations in Baghdad, has killed 62 people and wounded dozens more.
Many of the dead in the Iraqi capital were Shia pilgrims gathering for a religious festival.
In Hilla, two car bombs exploded near a restaurant, killing at least 19 people.
There has been a wave of attacks on the Shia community in recent days, as it marks the anniversary of the death of Shia Imam Moussa al-Kadhim.
A man who witnessed one of the attacks in Baghdad said a car bomb had targeted pilgrims and had also hit people who were working in the city.
The restaurant that came under attack in Hilla is said to be frequented by police.
