A car bomb exploded near an Iraqi army patrol on Thursday in the capital Baghdad, killing four people and wounding 10, an Interior Ministry source said.
Soldiers, civilians and members of the government-backed Sahwa militia of Sunni ex-insurgents were among the casualties in the Amiriya district of the Iraqi capital, the source said.
Overall violence in Iraq has dropped sharply since the height of sectarian war in 2006-07.
Iraq's new parliament is due to convene on Monday.
Iraqi security forces and members of the Sahwa militia appear to be bearing the brunt of the violence. The Sahwa, or Sons of Iraq, are former Sunni fighters who switched sides to fight al Qaeda.
