Police in Iraq say that at least 11 people have been killed in two separate explosions in the capital Baghdad.
Seven people died and a number of others were wounded in one blast, which occurred in a car park in east Baghdad.
The bomb was hidden under a car at a bus station. Police say four people were killed in a second attack, a roadside bomb in northern Baghdad.
Violence has dropped since security forces gained the upper hand against insurgents, but attacks still occur.
Iraqi security officials have been quoted saying insurgents are resorting to using smaller bombs and planting them in vehicles.
At least one woman was among the dead in the first attack in the Shia-dominated area of Mashtal in eastern Baghdad.
Elsewhere, the US military said two civilians died in a road accident involving US troops near the city of Tikrit, north of Baghdad.
Iraqi police said a Humvee vehicle hit four Iraqis as they were hanging a banner in the middle of a road.
