At least 10 people were killed and 35 wounded in a car bomb attack on a busy square in Baghdad's sprawling Sadr City district, police and medical sources stated.
There was no immediate claim of responsibility for Monday's attack but the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group regularly targets civilian areas in the heavily fortified capital.
Three bombs killed 29 people across the city on Saturday. An attack near the southern city of Najaf on Sunday left seven policemen dead.
US-backed Iraqi forces are currently fighting to push ISIL fighters from the northern city of Mosul, the armed group's last major stronghold in the country, but are facing fierce resistance.
Since the offensive began on October 17, elite forces have retaken a quarter of the city in the biggest ground operation in Iraq since the 2003 US-led invasion that toppled Saddam Hussein.
Prime Minister Haider al-Abadi has said the group would be driven out of the country by April.
