Officials said 29 people were killed and 107 wounded in 11 car bomb explosions in nine different parts of Baghdad. Most of killed and wounded were civilians, officials said.

In Falluja, about 60 kilometers (37 miles) west of Baghdad, five people were killed and 12 others were wounded when gunmen attacked al-Tahadi police station in southern Falluja.

Iraq has seen a sharp increase in friction between its Shiite and Sunni populations since April, when Iraqi security forces raided a site used by Sunni protesters to demonstrate against the Shiite-led government. Sunnis have felt politically marginalized under Shiite President Nuri al-Maliki, whose government fears it is being targeted by Sunni Islamists involved in fighting in neighboring Syria.

More than 800 Iraqis were killed and 2,030 wounded in violence and acts of terrorism in August, the United Nations said.
