At least 15 civilians have been killed as m ilitants unleashed a series of attacks in Shiite-majority areas of the Iraqi capital Baghdad.
The deadliest attack took place in the neighbourhood of al-Amil when a bomber set off his explosives-laden vest in a busy outdoor market, killing seven shoppers and wounding up to 25 others.
Another suicide attacker on foot blew himself up among shoppers in Mashtal, killing five civilians and wounding 15 others.
Three more civilians were killed and 10 were injured in a bomb explosion in a commercial area in the northern Sabi al-Bor area, police added.
No group has immediately claimed responsibility for the attacks. The extremist Islamic State group has claimed similar attacks in the past and, despite a series of battlefield defeats in recent months, the group still controls key areas in Iraq.
The Iraqi government is preparing to launch a major military operation, with air support from the US-led coalition, to retake IS-held Mosul this year.
As it has lost territory, IS has increasingly turned to insurgent-style attacks away from the front lines in an attempt to distract security forces and undermine government efforts to maintain security.
Violence claimed the lives of at least 1,003 Iraqis last month, including 609 civilians, according to the UN Assistance Mission to Iraq, known as UNAMI. At least 1,159 people were wounded in September.
In August, at least 691 Iraqis were killed and another 1,016 were injured.
