(CNN) -- At least 35 people were killed and more than 100 wounded in shootings and explosions across the country on Tuesday, officials with Iraq's interior ministry told CNN.
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.
In northern Mosul, about 400 kilometers (249 miles) north of Baghdad, a bomb exploded in the convoy of army Gen. Mohammed Khamas, killing him instantly. Khamas was the deputy head of army intelligence department in Mosul.
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.
