A string of car and roadside bombings across Iraq on Sunday killed at least 44 people and wounded more than 140 others, police officials told CNN.
The deadliest attack occurred in Kut when two car bombs exploded in a busy commercial street. Seventeen people were killed and 49 others wounded, according to police officials in the city, which is about 100 miles south of Baghdad.
Among the other worst attacks:
-- In the Sunni neighborhood al-Amriya in Baghdad, two bombs exploded at shops killing nine people and wounding 21 others. Other deadly attacks were also carried out in other parts of Baghdad.
-- In the Shiite city of Diwaniya, two car bombs exploded in an outdoor market, killing eight people and wounding 17 others. Diwaniya is about 118 miles south of Baghdad
-- In Samara, a Sunni town north of Baghdad, two bombs exploded in a busy market, leaving four dead and 11 others wounded.
Other attacks were carried out throughout Iraq, including the southern city of Basra near the Persian Gulf.
So far in 2013, more than 6,000 people have been killed in Iraq. Almost 1,000 of those deaths came in September.
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. The raid killed dozens and wounded more than 200.
