Last week, five people were killed and 17 injured in a bomb blast outside an ice-cream shop in Baghdad.
Also on Monday, Iraq's deputy oil minister was wounded in a bomb attack outside his house, security officials told the AFP news agency.
The bomb detonated as Saheb Salman Qutub was about to leave his home in Baghdad's northern Ataifiyah neighbourhood, they said.
"He [Qutub] escaped the assassination attempt by improvised explosive device close to his house on Monday morning," an Iraqi oil ministry statement said.
Qutb received treatment for minor injuries at a nearby hospital and was later discharged, the ministry said.
His driver was more seriously wounded and was admitted to hospital.
