Baghdad, Iraq - Seven people are killed in bomb attacks in two Shi'ite neighborhoods of Baghdad.
Police say a packed car bomb exploded on a commercial street in Baghdad's eastern Shi'ite district of Al Mashtal, killing at least five people and wounding 17, early Monday.
Around the same time, a bomb in a street cafe in the Al Shuala Shi'ite neighborhood of northern Iraq killed two and wounded ten others. A wave of car bombs and shootings across Iraq killed at least 36 people on Sunday, police sources said.
No group immediately claimed responsibility for the attacks, which appeared coordinated, but Sunni Islamist insurgents, including an al Qaeda affiliate, have been regaining momentum in recent months.
The civil war in neighboring Syria has aggravated sectarian divisions in Iraq, fraying an uneasy government coalition of Shi'ite, Sunni and ethnic Kurdish factions.
About 800 Iraqis were killed in August, according to the United Nations, with more than a third of the deadly attacks happening in Baghdad.
The bloodshed, 18 months after U.S. troops withdrew from Iraq, has stirred concerns about a return to the sectarian slaughter of 2006-7, when the monthly death toll sometimes topped 3,000.
