A series of attacks across Iraq have killed 17 people, including four Shiite militiamen and a Sunni tribal chief, officials said.
The deadliest attack happened when a car bomb went off on a commercial street in Baghdad's mainly Shiite Zafaraniyah district, killing seven people and wounding 15 others. Several shops were damaged.
Earlier, a roadside bomb targeted a Shiite militiamen convoy, killing four fighters and wounding seven in the area of Iskandariyah, just south of Baghdad.
Shiite militiamen have joined with Iraq's armed forces in their battle against the extremist Islamic State (IS) group, which has seized large swaths of land in the country's north and west.
Another bomb went off near an outdoor market in Baghdad's Shiite district of Obeidi, killing three shoppers and wounding 12, police said.
In northern Iraq, residents said Islamic State fighters killed Maiser al Waqaa, a Sunni tribal chief, along with two brothers in the village of al Houd, just south of Mosul.
They said al Waqaa ran in parliamentary elections earlier this year but failed to win a seat.
Sunni militants captured Mosul, Iraq's second largest city, and overran much of northern Iraq in June. The IS group has carved out a self-styled caliphate straddling the Iraqi-Syrian border.
Medical officials confirmed the casualties from all attacks.
