A car bomb killed six civilians and wounded 14 other people in the Shaab district of northern Baghdad today, police said.
One woman was among the dead, and three policemen were wounded in the attack, which targeted a police patrol.
The bombing comes at what has otherwise been a relative lull in violence in the Iraqi capital.
Violence in Iraq has dropped to four-year lows, which US officials credit to a surge in US troops last year, a rebellion by Sunni Arab tribal leaders against al-Qaeda and a ceasefire by anti-American Shia cleric Moqtada al-Sadr.
