Two bombs exploded near Sunni mosques in the Iraqi capital as worshippers left after Friday prayers, killing at least six people, as one more died in another attack, officials said.
The bombs -- one near a mosque in the Dura area and the second in Jihad -- also wounded at least 22 people.
The blasts were the latest in a series of sectarian attacks in the city, coming a week after two bomb explosions in a Sunni mosque north of the capital killed 18 people.
Last Saturday, bombings targeting Shiite mourners in Baghdad killed 73 people, while an attack on a Sunni funeral killed 12 the next day.
And another bombing against Sunni mourners in Baghdad killed 15 on Monday.
There are persistent fears of a return to the all-out Sunni-Shiite violence that peaked in 2006-2007 and killed tens of thousands of people.
The UN Refugee Agency said this week it was "increasingly concerned about the situation in Iraq, where recent waves of sectarian violence threaten to spark new internal displacement of Iraqis fleeing bombings and other attacks".
Some 5,000 Iraqis have been displaced this year, joining more than 1.13 million who had previously fled or been forced from their homes, it said.
Also on Friday, a bomb exploded near a policeman's house in the northern province of Nineveh, killing his mother.
The latest violence brings the death toll to more than 720 people in September and more than 4,550 this year, according to AFP figures based on security and medical sources.
